 Land Use Code Text Amendments – Entertainment Buffer
 City of Portland, Applicant

 Submitted to: Portland Planning Board Prepared by:
 Workshop Date: March 10, 2026 Kevin Kraft, Director
 Date Prepared: March 4, 2026 Matt Grooms, Deputy Director

I. INTRODUCTION
Review a proposed text amendment to Articles 3 (Definitions) and 6 (Uses) of the Land Use Code, co-
sponsored by Councilor Pelletier and Councilor Ali (Attachment A). The amendment would establish a
minimum 750-foot buffer requirement between large theaters and performance halls.

The Planning Board’s role is to review the proposed amendments for consistency with the Comprehensive
Plan and to provide a recommendation to the City Council to adopt, adopt with recommended
amendments, or reject the amendments. This recommendation must be supported by findings of fact and
an assessment of whether the proposal aligns with City policy and advances the goals and objectives of the
Comprehensive Plan. The City Council has the final authority to review and adopt any proposed changes to
the Land Use Code.

A legal advertisement for this workshop was published in the Portland Press Herald on February 26 and
February 27, 2026.

II. BACKGROUND
In response to community concerns raised during review of a Major Site Plan application for the proposed
3,300-capacity Portland Music Hall at 244 Cumberland Avenue, the City Council voted 6–3 on August 11,
2025 (Councilors Ali, Phillips, and Mayor Dion opposed) to enact a 180-day moratorium on theaters and
performance halls with capacities exceeding 2,000. The moratorium was made retroactive to applications
received on or after December 1, 2024 (Order 9-25/26). On February 23, 2026, the City Council voted to
extend the moratorium.

In response to the moratorium, on November 18, 2025, the Housing & Economic Development Committee
(HEDC) reviewed and discussed a proposed text amendment to the Land Use Code, introduced by
Councilor Pelletier and Councilor Ali. The amendment proposed to eliminate the existing 100-foot buffer
for businesses holding an entertainment license and replace it with a 750-foot buffer for large
entertainment businesses, which the amendment defined as venues with seating capacities of 1,000 or
more within the B-3 and Waterfront Central zones.

On February 3, 2026, the HEDC reviewed and discussed a refined text amendment co-sponsored by
Councilors Pelletier and Ali. The amendment would modify the existing Theater or Performance Hall use by
creating two categories: Theater or Performance Hall (Small) and Theater or Performance Hall (Large). It
would also prohibit Large Theaters or Performance Halls from being located within 750 feet of another
Large Theater or Performance Hall within the B-3 and Waterfront Central zones.

During deliberations on the proposal, HEDC members Phillips, Sykes, and Michniewicz expressed general


 1

 Page 3
opposition to the proposed 750-foot buffer. Councilor Michniewicz suggested considering a 250-foot
buffer due to concerns that entrances to large venues located near one another could create conflicts
when multiple venues are emptying at the same time and recommended that a 250-foot buffer be
considered. Ultimately, the committee voted 4-0 to forward the proposed amendments to the Planning
Board for review. However, the HEDC’s vote was solely to move the amendments forward for
consideration and did not constitute an endorsement of either a 250-foot or 750-foot buffer.

Adoption of Entertainment Sector Benefits for Large Venues
Since the enactment of the moratorium in August 2025, the HEDC reviewed a separate proposal on
October 21, 2025, to amend Chapter 4 of the City Code (Amusements) by establishing an Entertainment
Sector Benefits Agreement requirement for large venues. On November 18, 2025, the HEDC voted 4–0 to
recommend City Council approval of the amendment. On January 5, 2026, the City Council voted 8-0
(Councilor Ali absent) to pass Order 107-25/26, creating a new Large Capacity Entertainment License for
venues with capacities of 2,000 or more, and requiring licensees to enter into an Entertainment Sector
Benefits Agreement, providing financial or in-kind contributions equal to 1.0%–2.0% of the base ticket price
to support Portland’s local entertainment ecosystem. This ordinance became effective on February 5,
2026.

Existing 100-foot Entertainment License Buffer
In 2007, the City Council, guided by the Mayor’s Old Port Task Force and the Public Safety Committee,
created the existing Downtown Entertainment Overlay Zone, which included a 100-foot buffer between
establishments with alcohol service and entertainment licenses to address the impacts of a high
concentration of bars in the Old Port, many of which remained open late into the evening. The Task Force
concluded that the dispersal requirement effectively prevented the clustering of bars and entertainment
venues with music and dance licenses, which had been associated with public safety concerns, and
determined that a 100-foot separation from main entrances provided sufficient distance to mitigate these
impacts. This 100-foot dispersal requirement is codified in Section 6.8.4 of the Land Use Code for
businesses with entertainment licenses in the B-3 and Waterfront Central Zones and remains in effect.

III. PROPOSED TEXT AMENDMENTS
As outlined in Councilor Pelletier’s January 30, 2026 memo to the HEDC Committee (Attachment C), the
goal of the proposed amendments is to address concerns regarding the spacing of large venues in
downtown Portland. Establishing a buffer is intended to mitigate traffic impacts associated with patrons
arriving at and departing from multiple venues simultaneously.

The proposed amendments (Attachment A), co-sponsored by Councilor Pelletier and Councilor Ali, would
modify the existing Theater or Performance Hall use by creating two use categories, Theater or
Performance Hall (Small) and Theater or Performance Hall (Large), that would be defined in Article 3
Definitions:

 • Theater or Performance Hall (Small): An establishment with a total occupancy of fewer than
 1,000 persons devoted to showing motion pictures or hosting dramatic, musical, or live
 performances.

 • Theater or Performance Hall (Large): An establishment with a total occupancy of 1,000 or more
 persons devoted to showing motion pictures or hosting dramatic, musical, or live performances.

 Page 4
The 1,000-person threshold is derived from the Councilors’ original proposal. Theaters and Performance
Halls would continue to be permitted in the B-3 and Waterfront Central Zones (WCZ), as outlined in Table
6-C. However, Large Theaters and Performance Halls would be subject to supplemental use standards in
Section 6.4.42, which would prohibit such venues from locating within 750 feet of the primary entrance(s)
of another Large Theater or Performance Hall.

Under this approach, the 750-foot buffer would apply only between Large Theaters and Performance Halls.
It would not restrict proximity between small theaters and performance halls, nor would it apply to larger
venues such as stadiums or arenas, as currently drafted.

250 Foot Buffer Proposal
During the February 3, 2026 HEDC meeting, Councilor Michniewicz requested that staff explore a 250-foot
buffer. The intent of establishing a 250-foot separation would be to address concerns about two primary
entrances being located in close proximity and to mitigate impacts associated with patrons exiting venues
and entering the sidewalk/street network simultaneously.

IV. ANALYSIS
Staff evaluated the proposed amendments by reviewing current and historic policy guidance, regulatory
standards, and best practices in land-use planning, as well as analyzing parking conditions, the economic
activity of the arts and cultural sector, and regulations from other cities.

Policy and Regulatory Background
Portland’s adopted comprehensive policy framework, including Portland’s Comprehensive Plan, Portland’s
Plan 2030, One Climate Future, the Downtown Vision Plan, and the Portland Peninsula Transit Study, works
in concert with established regulatory tools such as the Land Use Code, Site Plan Ordinance, Traffic
Movement Permit (TMP) requirements, and impact fees to manage land use, transportation, site access,
and parking impacts. Together, these policies and regulations provide sufficient flexibility and oversight to
evaluate individual proposals on a case-by case basis while supporting the City’s long-standing goals and
commitment for encouraging compact, infill development, multimodal accessibility, and downtown
economic vitality.

Over the past decade, City policymakers have deliberately pursued policies that reflect a modern, 21st-
century approach to growth and sustainability. Long-range transportation planning has focused on creating
a more integrated, multimodal network through public transit enhancements, sidewalk and streetscape
improvements, bikeway planning, and targeted investments in the underlying street network. At the same
time, the City has worked to ensure that its land use framework is closely aligned with transportation planning.
The consistent direction of City policymaking over several decades demonstrates a shared commitment to
guiding Portland’s growth in a sustainable manner, prioritizing a transportation system that serves all users,
not solely automobiles and single-occupancy vehicles, and ensuring density, mixed-use development, and key
destinations are aligned with the public transit network. This commitment is increasingly reflected in
Portland’s built environment today.

For example, in 1991 the City adopted the Downtown Vision Plan. As Maine’s largest city and Northern New
England’s primary urban center, Portland’s Downtown serves as a vital hub for commerce, culture, and civic
life. In regards to transportation planning, the Downtown Vision Plan emphasized the need to reduce reliance
on single-occupancy vehicles and minimize on-site parking. It advocated for a more pedestrian-oriented
downtown, supported by transit, shuttle lots, carpools, biking, and walking. While acknowledging that



 3

 Page 5
reversing decades of car-centric development would take time, the plan called for a transitional approach,
warning that continued auto-dependence could result in increased congestion, pollution, and diminished
urban livability. Key transportation strategies outlined in the plan included limiting private on-site parking,
encouraging employer participation in transit programs, and enhancing the role of public transit within a
walkable, vibrant downtown core. This early policy direction laid the foundation for the City’s ongoing efforts
to create a more sustainable, accessible, and multimodal transportation system, and to support land use
regulation that encourages a shift away from car-centric development.

In 2009, the City approved the Portland Peninsula Transit Study, a study intended to advance transportation
strategies supporting the livability and sustainability of the Portland Peninsula, recognized as one of the most
vibrant and walkable small urban areas in the nation and the heart of the region. Building on prior policy
direction, the study emphasized the need to integrate land use, infrastructure, and transportation planning
to strengthen walking, biking, and transit options. The study acknowledged that while investments in
pedestrian, bicycle, and transit infrastructure are critical, meaningful reductions in single-occupancy vehicle
trips would also require addressing the financial incentives and convenience that favor driving. It highlighted
that many cities have chosen to accept some loss in auto-oriented conveniences in order to improve safety,
reduce emissions, and prioritize multimodal transportation. The plan reinforced the City’s long-standing
commitment to sustainable transportation and again set forth goals including reducing single-occupancy
vehicle trips, shifting away from auto-oriented infrastructure toward support for alternative modes, and
managing, rather than expanding, the existing parking supply.

Key policy recommendations included:
 ● Traffic Policy:
 ○ Shift from an auto-oriented infrastructure to promotion of other modes;
 ○ Shift investment strategy from support for new lanes of asphalt to transit;
 ○ No longer designing streets solely to accommodate peak-hour traffic;
 ○ Accepting traffic delays as normal in an urban environment
 ● Transit Policy:
 ○ Encourage development of transit to reduce the growth of traffic to and within the
 peninsula;
 ○ Provide convenient, frequent, attractive, reliable, and safe transit options;
 ○ Invest in transit over new vehicular travel lanes of asphalt
 ● Parking Policy:
 ○ Encourage new initiatives to decrease the growth of traffic volumes;
 ○ Manage the parking supply rather than continue to expand it;
 ○ Use parking impact fees to support transit;
 ○ Develop shared parking
 ● Pedestrian & Bike Policy:
 ○ Encourage walking and biking, along with transit “share the street”

In 2017, the City adopted Portland’s Plan 2030, the Comprehensive Plan for the City of Portland. As a
foundational policy document, it establishes the framework that guides zoning, the Land Use Code, and other
adopted regulations. The Plan outlines goals and strategies aimed at reducing reliance on automobiles
through compact, walkable, and multimodal development, strategically managed parking, and reinforcement



 4

 Page 6
of the city center, recognizing that Downtown Portland remains the region’s cultural, civic, and economic
hub.

Its transportation and land use policies emphasize that by managing growth in automobile traffic, the City
can expand transportation choices and foster a more accessible and sustainable urban environment.
Additionally, the Comprehensive Plan’s economic policy framework acknowledges that Portland hosts an
increasingly diverse economy, including the financial and service sectors, a thriving local food scene, a port
engaged in international trade, a regional healthcare hub, and a flourishing arts and culture community. The
Plan outlines the following goals relevant when considering the proposed amendments:
 • Promote an economic climate that increases job opportunities and overall economic well-being
 (State Goal).
 • Create economic prosperity by growing Portland’s tax and employment base (Local Goal).
 • Value innovation and creativity as cornerstones of the local economy and central to Portland’s
 uniqueness and diversity (Local Goal).
 • Support sustainable growth in educational, medical, and cultural institutions (Local Goal).
 • Target areas for job growth by ensuring new employment can be accommodated in priority growth
 areas across the city and by evaluating zoning and infrastructure conditions in downtown,
 neighborhood nodes, and along transit corridors to support employment and housing growth.
 • Emphasize arts and culture by leveraging them as defining elements of Portland’s quality of place,
 supporting cultural institutions and arts spaces, and ensuring access to arts and culture for all
 residents.

The Plan’s, Future Land Use Framework further emphasizes areas most critical to the City’s continued growth
and highlights the goal to “Reinforce the Center.” The Plan affirms that Downtown Portland remains central
to the region’s arts and cultural, economic, and civic vitality and embraces the principle that downtown
should continue to serve as a primary locus of activity for the broader region. Downtown is therefore
identified as a priority growth node for continued enhancement and investment.

Portland’s Plan 2030 laid the foundation for further studies and policy development, including One Climate
Future, approved in 2021. One Climate Future continued to move the City toward the goal of sustainable
growth. This adopted policy document included specific goals and strategies to support implementation of
the higher-level direction in Portland’s Plan 2030. These goals and strategies again focused on mode shift,
aiming to decrease private vehicle use and focused on expanding public transportation systems, biking
accessibility, complete streets, and transit-oriented development (TOD) in an effort to make it easier to travel
between destinations without a car and to reduce greenhouse gas emissions.

A key action item identified in One Climate Future was to shift away from policies that promote increased
parking demand and supply, and instead advance strategies that strengthen multimodal transportation
options. To achieve this, the plan called for eliminating parking minimums in commercial areas and along
designated transit corridors, and for establishing parking maximums. This was accomplished in 2024 through
ReCode, when parking minimums were eliminated citywide and replaced with parking maximums.
Furthermore, by encouraging lower-density, car-oriented development, excessive parking also undermines
public transit efficiency and creates streetscapes that discourage walking and biking. This reinforces car
dependency, increases greenhouse gas emissions, and perpetuates demand for more parking, directly
conflicting with the goals of One Climate Future.

In recent years, the City and region have continued to advance their multimodal transportation goals. In 2023,


 5

 Page 7
the Gorham-Westbrook-Portland Bus Rapid Transit (BRT) Study was completed to assess the feasibility
and potential benefits of a rapid transit connection linking the three communities. The study identified a
preferred alignment, running along Main Street, Brighton Avenue, and Congress Street through downtown
Portland, as the most direct and effective corridor. This route would connect major destinations, including
USM Gorham, Gorham Village, Downtown Westbrook, Rock Row, USM Portland, Maine Medical Center,
Downtown Portland, and the Eastern Waterfront, with high-frequency bus service.

On April 14, 2025, the City Council adopted the Greater Portland Council of Governments’ (GPCOG) Regional
Vision Zero Action Plan. By doing so, the City formally endorsed the initiative’s core objective: eliminating
all traffic-related fatalities and serious injuries by 2045. The GPCOG Vision Zero plan emphasizes reducing
reliance on single-occupancy vehicles and promoting greater use of public transit as a critical step toward
safer, more equitable mobility. Directly aligned with advancing Vision Zero, the City Council in 2025 adopted
an update to the City’s 2012 Complete Streets Policy to ensure it continues to reflect the community’s vision
for a safer, more multimodal city that serves all users, regardless of age or ability.

Policy & Regulatory Considerations:

 • Portland’s Plan 2030 identifies downtown as the region’s center for arts, culture, and commerce.
 Theaters and performance halls contribute to this role as components of the city’s cultural and
 economic activity. Existing and former venues, including the State Theatre, Merrill Auditorium, Cross
 Insurance Arena, Blue, Portland House of Music, and Port City Music Hall (Closed), demonstrate that
 such uses have operated successfully in the downtown area.
 • Economic development activity in downtown Portland may create opportunities for arts and cultural
 venues that generate visitor activity, support employment, and contribute to the local tax base.
 Permitting theaters and performance halls downtown is consistent with broader goals related to
 encouraging foot traffic, supporting mixed-use development patterns, and reinforcing downtown’s
 role as a center for arts, culture, and commerce. Such venues may also influence overall downtown
 activity levels and have spillover effects on nearby businesses.
 • Theaters and performance halls subject to site plan review must be designed to address potential
 impacts on vehicular and pedestrian circulation, noise, and adjacent streets. These projects are
 reviewed and regulated in accordance with the City’s Site Plan Ordinance and the State’s Traffic
 Movement Permit (TMP) requirements.
 • One Climate Future prioritizes shifting travel away from single-occupancy vehicles. Downtown
 venues may support this objective by providing locations that are accessible by walking, public transit,
 and other alternative modes of transportation.
 • The Gorham–Westbrook–Portland BRT study identifies Congress Street through downtown as a key
 corridor connecting Portland with Gorham Village and downtown Westbrook, with the potential to
 enhance high-frequency bus service at both the local and regional levels.
 • Updates to the Vision Zero and Complete Streets policies emphasize the City’s commitment to a
 street network that accommodates all users and modes, with a focus on reducing reliance on single-
 occupancy vehicles and supporting alternative modes of travel, including public transit, walking, and
 biking.

Parking Capacity & Utilization
While parking has been a frequent topic of conversation for several decades, in 2017 the City
commissioned a study covering much of the downtown and nearby waterfront areas, which found that
there are enough parking spaces to accommodate roughly one space for every four residents of Portland.


 6

 Page 8
The study showed that peak utilization typically occurs on weekday afternoons in the summer, when
businesses and offices are open, with demand tapering off by early afternoon and continuing into the
evening. More recent studies and analyses have yielded similar findings.

Parking Study for Downtown, the Old Port, and the Eastern Waterfront (2017)
In 2017, the City commissioned a parking study covering the downtown, central waterfront, eastern
waterfront, and a ¼-mile buffer surrounding these areas (Attachment D). The primary objectives were to
collect data on parking supply and demand during both weekdays and weekends and to identify any areas of
deficiency.




Figure 1: 2017 Parking Study – Study Area Map

The study identified a total supply of nearly 16,000 parking spaces (on-street, surface lot, structured parking)
within the study area, or roughly one space for every four residents of the City of Portland (~25% of Portland’s
entire population). Of these, over 11,000 spaces were located within the core downtown area. The analysis
found that peak parking demand occurs on weekday afternoons during the summer, when office and
businesses are open and visitors are abundant, and demand exceeds the system’s effective capacity 1, though
not its total capacity (Figure 2). On these peak weekdays, utilization begins to decline starting around 2:30
PM and continues to remain low, below the system’s effective capacity, into the evening hours. In contrast,
weekend peak demand during the summer season was significantly lower in general, reaching only 71% of
effective capacity (Figure 3).



1
  Effective Capacity: The effective capacity is a concept in parking analysis that refers to the occupancy level at which
parking users begin to have difficulty finding open spaces and vehicle circulation to access parking begins to exhibit
signs of congestion including queuing. The effective capacity is also thought of as the threshold when a parking
supply begins to be perceived by users to be full.



 7

 Page 9
The study documented a strong preference for on-street parking, which was at or above effective capacity
during weekday and Saturday evenings, despite the fact that substantial capacity remained in nearby surface
lots and parking garages during those same periods. The study also highlighted that individual streets varied,
and some high-demand streets, such as Commercial Street, Middle Street, and Exchange Street, exhibited
higher occupancy rates than the overall sample within the study area.

The 2017 study also included a land-use-based analysis of parking demand. Using ITE parking generation
factors, which are based on generalized national data and are often characterized as conservative in urban
contexts, the study concluded that evening and weekend events at a sold-out Cross Insurance Arena, with a
seating capacity of approximately 6,700, appeared to be adequately supported by existing parking in
Downtown Portland. The study indicated approximately 5,000 spaces would be available during the peak
period of a sold-out weekday event (Figure 4) and approximately 2,000 spaces would be available during the
peak period of a sold-out Saturday event (Figure 5).

Rather than recommending the construction of additional parking facilities, the study concluded that the City
should focus on more efficient management of the existing supply. Recommendations included encouraging
greater use of underutilized surface lots and structured parking facilities, particularly during peak demand
periods.

Current parking occupancy data
As of today, parking capacity in the area remains similar to past levels. The City of Portland Parking Division
conducted a parking lot occupancy assessment of parking lots and garages open to the general public within
both a ¼ mile of the proposed Live Nation Portland Music Hall, and ½ mile of the proposed venue on a
Thursday, Friday, and Saturday in May of 2025. Each lot was counted at least twice, and in some cases, up to
four times, over the three-day period with all counts occurring after 5:00 PM.

The results showed that of the approximately 2,700 parking spaces within a ¼-mile radius of the proposed
Live Nation Portland Music Hall, the average utilization rate between 5:30 PM and 8:00 PM was 19% (Table 1).
For parking spaces located between ¼ and ½ mile from the venue, utilization after 5:00 PM averaged 18%
(Table 2). These findings suggest that roughly 80% of the parking supply remained available during those
times, indicating sufficient existing capacity to support the proposed venue and other uses. These findings
are consistent with the 2017 study and reflect a broader trend of reduced parking demand, particularly during
evening hours. With utilization below 20% and available capacity at approximately 80%, these numbers
indicate that parking capacity remains within the existing supply, aligning with the recommendations of both
the 2009 Portland Peninsula Study and the 2017 study, which advised the City to focus on managing the
existing parking supply rather than expanding it.

Portland Music Hall Traffic Movement Permit (TMP) Parking Analysis

Given that the proposed music venue includes no on-site parking, in accordance with zoning requirements,
the project’s Traffic Movement Permit (TMP) included an analysis of existing parking to understand trip
distribution within the surrounding area. The applicant provided a map of available off-street parking facilities,
including garages and lots, identifying the total number of spaces within four-tenths of a mile of the site
(Figure 6). These facilities were documented in the March 2025 City of Portland Parking Division’s Annual
Parking Survey. Based on distance to the venue, current hours of operation, and capacity, the applicant
identified five lots and garages as the most likely parking destinations for music hall patrons (Figure 7). Those
five facilities alone account for approximately 2,800 total parking spaces.

Additionally, as part of the Portland Music Hall Major Site Plan Application, the applicant’s Transportation
Demand Management (TDM) Plan highlights the venue’s central Downtown location and centers its
strategies on access to and from the site on modal split and vehicle occupancy. The TDM materials estimate
a total of 1,385 one-way vehicle trips, including both attendees and employees. The projected mode share is
82% vehicles, 2% transit, and 16% walking or biking. The applicant’s TDM submission also sets a target to
reduce personal vehicle use by 10%, aiming for a modal split of 72% vehicles instead of 82%, which would
further decrease parking demand. In summary, when comparing the estimated parking demand to the
effective parking capacity downtown, there is sufficient parking available to accommodate demand, even
under the more conservative 82% vehicle mode share.

Parking Capacity & Utilization Considerations
 • Parking utilization studies indicate that the peninsula benefits from a strong transportation
 network, including access to multiple bus routes and a walkable street grid. Establishing a 750-foot
 buffer between Large Theaters and Performance Halls may result in some new venues locating in
 areas with reduced accessibility, walkability, or transit options, which could influence travel mode
 choices and parking demand.
 • Expanding the buffer from 100 feet to 750 feet would reduce the number of potential locations for
 new venues in the central downtown area. Other sites within the B-3 Downtown Business zone




 12

 Page 14
 would remain available, and venues in these areas may continue to rely on the same parking
 facilities and traffic patterns.
 • The B-3 Downtown zone includes numerous hotels. Visitors staying downtown to attend a show at
 a theater or performance hall could rely on walking, public transit, or taxi/rideshare services due to
 the close proximity of these uses.
 • Several existing venues operate without on-site parking and continue to function under current
 conditions. New venues could potentially be accommodated through a combination of nearby
 public parking facilities, transit access, walkability, bicycle infrastructure, and visitors lodging within
 the city.
 • One Climate Future identifies a key action to shift away from policies that increase parking demand
 and supply, and to advance strategies supporting multimodal transportation. The plan reinforces
 the City’s long-standing commitment to sustainable transportation and outlines goals such as
 reducing single-occupancy vehicle trips, prioritizing alternative modes over auto-oriented
 infrastructure, and managing rather than expanding the existing parking supply.
 • Does the proposed text amendment align with the Comprehensive Plan and advance the goals and
 objectives outlined in One Climate Future as it relates to parking?
 • Are existing regulatory procedures sufficient to address the concerns identified in the stated
 purpose of the proposed text amendment?

Creative Economy (Theaters & Performance Halls Downtown)
As outlined in Creative Portland’s Local Economy Report for FY2025 (July 1, 2024–June 30, 2025), sustaining
the arts community and promoting Portland’s cultural life are central economic development priorities.
Portland is home to more than 150 arts and cultural organizations that contribute significantly to the City’s
vibrancy and creative identity. The report emphasizes that the arts function as a key economic driver,
powering the creative economy and playing an important role in workforce recruitment and retention.

These findings are reinforced by the October 2023 Arts & Economic Prosperity study, which concluded that
Portland’s nonprofit arts and culture industry generated $86 million in economic activity in 2022. This
included $58.2 million in spending by nonprofit arts and cultural organizations and $27.8 million in event-
related spending by audiences. Collectively, this activity supported 1,872 jobs and generated $20.7 million in
local, state, and federal government revenue.

Within Portland, many venues operate on the peninsula, defined as east of I-295. The B-3 zone, which
encompasses downtown and the Arts District, is home to many of the City’s theaters and performance halls
with varying capacities. Existing zoning regulations permit theater and performance hall uses by right, a
framework that has allowed Portland’s creative economy to grow organically. This flexibility has supported
the continued evolution of Portland’s arts and culture sector and fostered a diverse and dynamic venue
landscape (Table 3). Furthermore, many of these venues operate without dedicated on-site parking,
loading areas, or designated on-site tour bus parking.

When on-street space or street closure is needed for buses or tour buses, venue operators apply for a
Street Occupancy Permit, which is reviewed and issued by the Department of Public Works (DPW). For
larger events, whether sporting events or performances at theaters and other venues, venue operators are
responsible for securing and funding any required police details to support with crowd control and




 13

management. Requests are submitted through the Police Department’s website, which facilitates the
coordination of services such as traffic control and pedestrian crossings before and after events.

From a professional sports perspective, Portland was named the #1 Minor League Sports Market in the
country in 2024 by Sports Business Journal. The city is home to several teams that draw visitors from
Portland and across the region and beyond. The Portland Sea Dogs, the Double-A affiliate of the Boston
Red Sox, welcomed 366,442 fans during the 2025 season, including 25 sold-out games. The Maine Celtics,
the NBA G League affiliate of the Boston Celtics, recorded total regular-season attendance of 54,052 during
the 2024–2025 season. The Maine Mariners, affiliated with the Boston Bruins (NHL), averaged 4,521 fans per
game over the same period. In 2025, the Maine Hearts of Pine launched their inaugural United Soccer
League (USL) season, drawing sold-out crowds at Fitzpatrick Stadium. The team set a USL single-game
attendance record of 6,440 and averaged 5,811 fans across 14 home matches. Additionally, for the 2026
season, the Hearts of Pine have sold out both season tickets and single-game tickets for all home games.

National Case Studies
To inform discussion of potential amendments related to theaters and performance halls, staff reviewed a
range of jurisdictions to understand how other communities regulate and permit theaters, live
performance venues, and similar assembly uses. The selected jurisdictions reflect a mix of regional
comparators and cities with active cultural and entertainment environments, including nearby New England
communities, mid-sized cities with vibrant downtowns, and larger cities with established entertainment

 • Mid-Sized Cities with Active Downtown Cultural Scenes: Cleveland, OH; Buffalo, NY; Asheville,
 NC; Provo, UT; Greenville, SC.
 • Larger Cities with Established Entertainment Economies: New York, NY; Austin, TX; Boston, MA;
 Portland, OR; Nashville, TN; Seattle, WA

A summary of this review is provided in Attachment B.

Creative Economy Considerations
 • Portland’s Plan 2030, identifies the creative economy as an important component of the city’s
 overall development framework and emphasizes maintaining downtown as the regional center for
 arts and culture. The plan notes that arts and cultural activities contribute to Portland’s quality of
 place and calls for supporting cultural institutions and spaces.
 • The plan emphasizes that economic development should support growth in Portland’s tax base and
 employment, with new opportunities directed toward priority growth areas across the city.
 Downtown Portland serves as a regional hub, where arts and cultural spaces can contribute to
 economic activity and employment.
 • The October 2023 Arts & Economic Prosperity study reported that Portland’s nonprofit arts and
 culture industry generated $86 million in economic activity in 2022. This included $58.2 million in
 spending by nonprofit arts and cultural organizations and $27.8 million in event-related spending by
 audiences. Collectively, this activity supported 1,872 jobs and generated $20.7 million in local, state,
 and federal government revenue.
 • Nationally, cities regulate arts and entertainment venues differently, with many encouraging such
 venues to locate in mixed-use or downtown areas.
 • Portland’s B-3 Downtown Business zone currently includes a 100-foot buffer, established in 2007
 with the Downtown Entertainment Overlay Zone (DEOZ) to address public safety concerns related
 to late-night bars, particularly near Wharf Street. Seated, ticketed performance venues differ from
 these establishments in that they generally provide greater oversight, crowd management, and
 operational control. Consideration may be given to whether expanding the buffer beyond 100 feet
 would further mitigate potential crowd or traffic-related impacts.
 • The City has a variety of venues of different sizes, including professional sporting facilities with
 capacities exceeding 6,000. Seated, ticketed venues have a limited history of complaints or public
 safety concerns, in contrast to the bars in the Old Port that prompted the original buffer. Site
 access, circulation, and traffic impacts are addressed through existing regulations and the City’s
 development review process, which provide ongoing oversight and require mitigation measures as
 needed.
 • Restrictions on venues may influence development patterns by encouraging new venues to locate
 in neighboring communities, potentially affecting local economic activity, tax revenue, and
 employment, while Portland venues continue to compete for patrons. Downtown Portland, as
 Maine’s most walkable and transit-accessible area, provides the greatest opportunity for attendees
 to access venues using alternative modes of transportation, supporting the City’s multimodal




 15

 mobility goals and, consistent with One Climate Future, helping to reduce greenhouse gas
 emissions from vehicle trips.

V. PUBLIC COMMENTS
During the February 3, 2026, HEDC committee meeting, public testimony opposing the proposal raised
concerns about singling out a specific project, noted that the proposed music hall complies with all zoning
requirements without requesting any variances, and emphasized the importance of supporting downtown
economic development and the role of such venues in maintaining a vibrant downtown, while suggesting
that a buffer would not be appropriate.

Testimony in support of establishing a buffer focused on parking and life-safety concerns, including
emergency access and site circulation. Staff note that Portland hosts several major sporting venues,
theaters, and performance halls that operate successfully in dense urban areas. Life-safety access and
crowd evacuation are addressed through required emergency and evacuation plans, which are reviewed by
the Fire Department as a condition of occupancy permits. For larger events, tenants are responsible for
arranging and funding any necessary police details, coordinated through the Police Department to manage
traffic and pedestrian safety. Site access and circulation are also regulated through the City’s Site Plan
Ordinance and are outside the scope of zoning considerations.

VI. NEXT STEPS
The purpose of this Planning Board workshop is to introduce the proposal, provide background context,
and allow the Board to ask questions, deliberate, and offer direction to staff. The Board in reviewing the
proposal should consider if the proposed text amendment advances the goals and objectives of the
comprehensive plan or other relevant policy documents.

Following the workshop, a public hearing on the proposed amendments will be scheduled, at which the
Board will evaluate the proposal for consistency with the Comprehensive Plan and adopted citywide
policies and make a recommendation to adopt, adopt with amendments, or reject it.

Planning & Urban Development Department
RE: Performance Hall Regulations - Case Studies Addendum



I. OVERVIEW
To inform discussion of potential amendments related to performance venue regulation, staff reviewed a
range of peer jurisdictions to understand how other communities permit and regulate theaters, live
performance venues, and similar assembly uses.

This review is based on outreach to peer planners and a review of relevant zoning and regulatory
frameworks, providing both ordinance-level context and insight into how performance venues are
regulated in practice.

II. SELECTION OF PEER COMMUNITIES
Peer communities were selected to reflect a mix of regional comparators and cities with active cultural and
entertainment environments, including nearby New England municipalities, mid-sized cities with vibrant
downtowns, and larger cities with established entertainment economies or strong live music identities. This
range was intended to provide a balanced perspective across different governance scales and mobility
contexts, including cities with robust public transportation systems as well as more auto-oriented
communities, with some peers offering direct comparability to Portland and others illustrating how
performance venues are regulated in larger or more specialized cultural settings.

III. CASE STUDIES
The jurisdiction names below are hyperlinked to each community’s publicly available zoning or land
development ordinance for reference.

A. Regional and Comparable New England Cities

1. Worcester, MA
 Worcester regulates theaters and performance venues primarily through broad zoning permissions,
 with limited use-specific standards embedded in the zoning code. Theaters and concert halls are
 generally allowed in non-residential districts, including downtown, and the City does not impose
 spacing requirements or venue-specific overlays.

 Many of Worcester’s larger venues are located in historic or publicly supported facilities, and zoning
 has historically played a limited role in shaping their location. Downtown districts containing venues do
 not require off-street parking, and logistical considerations such as loading, crowd management, and
 traffic circulation are typically addressed through site design, transportation planning, and event
 coordination rather than zoning regulations.

 As residential development has increased downtown, the city has begun to face more concerns about
 noise, parking demand, and crowd activity, but these issues are not currently addressed through
 targeted zoning tools.




 Page 62
Planning Board Workshop – Performance Hall Regulations Case Study March 10, 2026



2. Burlington, VT
 Burlington regulates performance venues through a combination of zoning permissions and
 discretionary review, with performing arts centers subject to conditional use review in certain districts,
 which allows the city to evaluate potential impacts, such as traffic, noise, and neighborhood
 compatibility, on a case-by-case basis.

 Peer outreach also highlighted recent regulatory changes in specific districts. For example, a prior size
 limitation on performing arts centers in a mixed industrial district was recently removed in connection
 with the potential relocation of a major regional venue. Planner input also noted that venue operations
 in some locations may be influenced by Vermont’s Act 250 permitting process, which can impose
 event-related conditions at the state level.

3. Portsmouth, NH
 Portsmouth regulates performance venues through zoning standards that differentiate between indoor
 and outdoor facilities. Performance facilities are generally permitted by right in mixed-use and
 downtown districts, with indoor venues required to maintain a minimum distance of 200 feet from any
 residential or mixed-residential district, and outdoor venues required to maintain a minimum distance
 of 500 feet. Additionally, indoor facilities are limited to operating hours of 8:00 AM to 11:00 PM, while
 outdoor facilities may operate between 4:00 PM and 11:00 PM.

 It was noted that downtown venues typically do not require off-street parking and that relatively few
 ongoing operational conflicts have been reported related to venue activity.

4. Providence, RI
 Providence regulates theaters and performance venues through a combination of zoning permissions
 and cultural policy initiatives centered in its downtown. Based on a review of their local ordinances,
 performance venues are located primarily within the downtown district, which has long functioned as
 the city’s primary arts and entertainment hub.

 Zoning allows performance venues within downtown mixed-use districts, with discretionary review
 applied in some cases, depending on scale and context. The city has historically supported clustering of
 venues through broader policy initiatives, including public investment in historic theaters and incentives
 intended to reinforce downtown as a cultural destination.

 Providence’s regulatory framework extends beyond zoning. In addition to land use controls, the city has
 explored operational and policy tools related to venue activity, including discussions of ticket
 surcharges for larger venues and continued public investment in arts and entertainment infrastructure.

B. Mid-Sized Cities with Active Downtown Cultural Scenes

1. Cleveland, OH
 Cleveland regulates theaters and performance venues through zoning permissions in downtown and
 commercial districts. Based on a review of the City’s ordinances, performance venues are permitted in
 a range of commercial and downtown districts, including areas that contain established cultural
 destinations such as Playhouse Square.



 2


 Page 63
Planning Board Workshop – Performance Hall Regulations Case Study March 10, 2026



 The City also applies an Entertainment Overlay District in select areas. The overlay supplements the
 underlying zoning districts by allowing a defined set of entertainment and nightlife uses, including
 theaters, nightclubs, and similar venues, within designated areas intended to accommodate
 concentrated entertainment activity. The overlay also includes provisions governing the concentration
 of adult entertainment uses within these districts.

2. Madison, WI
 Madison has a diverse range of performing arts venues. These include newer large performing arts halls
 (three theaters of varying sizes, with the largest at approximately 2,200 seats) located directly across
 from a historic 1,800-seat theater, as well as a separate 2,500-seat venue. The city also includes a
 historic 1,000-seat theater near a former church converted into a 700-person standing-room music
 hall in a neighborhood commercial district.

 In addition to performing arts venues, Madison is home to major sporting facilities, including the
 approximately 17,000-seat Kohl Center, which hosts University of Wisconsin hockey and basketball
 games as well as major concerts and events, and Camp Randall Stadium, an approximately 76,000-seat
 outdoor stadium that hosts University of Wisconsin football games and large-scale concerts.

 Theaters, assembly halls, and concert halls are permitted uses in multiple downtown zoning districts.
 The City does not impose density or spacing requirements for these venues. Site access, circulation,
 and loading are addressed through the site plan review process.

3. Buffalo, NY
 Buffalo regulates entertainment uses through a combination of base zoning permissions and a targeted
 downtown overlay. Based on a review of the City’s ordinance, the underlying zoning districts establish
 where entertainment uses such as theaters, performance venues, and similar assembly uses are
 permitted.

 The City also applies the Downtown Entertainment Review Overlay (N-DER) in portions of downtown
 with concentrated nightlife activity. Within the overlay area, the underlying zoning permissions remain
 in effect; however, certain late-night entertainment activities may be subject to additional review and
 permitting requirements. These provisions are intended to address potential operational and public
 safety considerations associated with higher-intensity nightlife activity, including events where alcohol
 is served, and large crowds may be present. As structured, the overlay functions as a targeted layer
 applied on top of the underlying zoning districts within designated downtown areas.

4. Asheville, NC
 Asheville regulates performance venues through a combination of zoning permissions and operational
 regulations. Peer input indicates that performance venues are permitted in higher-intensity commercial
 districts, including the central business district, and the zoning ordinance does not include spacing
 requirements between venues.

 Much of the regulatory framework identified through peer outreach is operational rather than zoning-
 based. Asheville’s noise ordinance plays a significant role in managing venue impacts, with larger or
 louder venues requiring a sound exceedance permit that establishes limits on decibel levels, hours of
 operation, and the number of permitted events.

5. Provo, UT
 Provo regulates theaters and performance venues through its base zoning framework rather than
 through a dedicated entertainment overlay or venue-spacing standard.

 Under Provo’s zoning code (Title 14), land uses are organized by defined categories and permitted
 within specific zoning districts through district use tables. Theaters and similar assembly-oriented uses
 are regulated through those use tables, which establish where the use is permitted outright and where
 additional land use review may be required.

 In addition to determining where such uses may locate, zoning establishes applicable development
 standards, including building height, setbacks, lot coverage, and off-street parking requirements tied to
 use category. Where discretionary review is required, the City may evaluate compatibility
 considerations such as traffic circulation and impacts on surrounding properties. The code does not
 establish venue-to-venue spacing requirements between entertainment uses. Operational matters,
 including occupancy limits and alcohol service, are governed outside zoning through building and
 licensing regulations.

6. Greenville, SC
 Based on peer input, Greenville recently adopted an Entertainment District Overlay focused on a four-
 block area of downtown where a high concentration of bars and nightclubs had developed. The
 Planning Commission recommended approval of the overlay in November 2025, and City Council
 approved it at the end of the year. The overlay applies within a defined geographic area and
 supplements the underlying zoning regulations in that portion of downtown in response to the
 concentration of late-night uses.

 In addition to zoning, Greenville utilizes a cross-departmental review body currently referred to as the
 Technical Advisory Committee, which is being renamed the Staff Technical Advisory Team (STAT). This
 team includes representatives from police, fire, building codes, planning, parks and recreation, and
 business licensing. The team reviews late-night, indoor, and outdoor entertainment uses and evaluates
 business plans and operational logistics such as hours of operation, loading and unloading, staffing
 plans, security plans, and the relationship between food and alcohol service. This process functions as
 an operational review mechanism separate from base zoning permissions.

 With respect to large-scale venues, including the Bon Secours Wellness Arena and a proposed outdoor
 amphitheater in the downtown area, the City has considered engaging third-party acoustic engineering
 review to evaluate noise levels and identify mitigation strategies.

C. Larger Cities with Established Entertainment Economies

1. New York City, NY
 New York City regulates performance venues primarily through zoning permissions that vary by district
 and use category. Based on peer outreach, the Zoning Resolution generally does not include spacing
 requirements between venues, meaning that if a use is permitted in a zoning district, it may locate near
 similar uses.

 Theaters are broadly permitted as-of-right in many commercial and manufacturing districts. The zoning
 framework distinguishes between traditional theaters and larger assembly uses, with larger venues

 4

Planning Board Workshop – Performance Hall Regulations Case Study March 10, 2026



 more likely to require additional review or special permits depending on scale. New York City also
 employs specialized zoning tools in the Theater Subdistrict, such as restricting the demolition of
 theaters and provides floor area bonuses for new theater space. Parking requirements vary by district
 density, with no parking required in higher-density areas and capacity-based ratios applied in lower-
 density districts.

2. Austin, TX
 Austin regulates theaters and performance venues through zoning permissions and targeted incentive
 programs. Based upon a review of the City’s ordinances, the zoning code distinguishes between
 theaters and performance venues and allows these uses in central districts, including downtown.

 Austin also incorporates live music into its development bonus framework. Through density bonus
 programs, projects may receive additional development capacity in exchange for incorporating and
 maintaining live music venues. These programs include requirements related to long-term operation,
 soundproofing, and continued use of the space as a live music venue.

3. Boston, MA
 Boston regulates theaters and performance venues through district-based zoning permissions
 supplemented by project-level review and licensing requirements. Based upon a review of the City’s
 ordinances, entertainment and cultural uses are permitted or conditionally allowed in certain mixed-use
 and commercial districts, with larger venues subject to additional development review depending on
 scale.

 Boston does not include spacing requirements between venues in zoning. Instead, venue activity is
 addressed through a combination of zoning permissions, project-level review, and separate licensing
 and noise regulations. Major venues are concentrated in areas such as the Theater District, where
 multiple performance spaces are located within a compact downtown setting.

4. Portland, OR
 Portland regulates theaters and performance venues through its use-category framework in Title 33 of
 the Planning and Zoning Code. The code does not define “music halls” or “concert venues” as
 standalone uses, but instead classifies entertainment uses within broader categories.

 Under Chapter 33.920, theaters are classified as part of the Retail Sales and Service use category. Larger
 facilities drawing substantial event attendance are categorized as Major Event Entertainment, which
 includes uses such as stadiums, arenas, coliseums, auditoriums, exhibition and meeting areas, and
 fairgrounds. This classification determines how the use is treated for zoning purposes.

 Whether a performance venue is permitted depends on the underlying zoning district. Title 33 use
 tables establish where these uses are allowed outright and where conditional use review is required.
 Zoning also regulates development standards applicable to such uses, including building height,
 setbacks, and off-street parking requirements where applicable.

 Portland does not impose minimum spacing requirements between entertainment venues. Operational
 aspects of venue activity, including sound levels, hours of operation, occupancy, and alcohol service,
 are regulated outside the zoning code through separate noise, building, and licensing frameworks.


 5

Planning Board Workshop – Performance Hall Regulations Case Study March 10, 2026



5. Nashville, TN
 Nashville regulates theaters and related entertainment uses through its zoning district framework,
 which assigns specific uses to zoning districts and establishes development standards applicable to
 those uses. In the Metro Zoning District Land Use Table, “Theater” is listed under “Recreation and
 Entertainment Uses,” and the table identifies the zoning districts in which that use is permitted. Outside
 downtown, the underlying zoning designation determines whether a theater is permitted outright or is
 subject to additional land-use review.

 Zoning also regulates physical development standards applicable to theater uses. These standards
 include requirements related to building height, setbacks, lot coverage, and off-street parking. Parking
 requirements are tied to use category and are typically calculated based on the nature or scale of the
 use. In areas governed by the Downtown Code, parking standards may be reduced or structured
 differently than in conventional zoning districts.

 Within the downtown area, theaters and other entertainment uses are regulated under a separately
 adopted Downtown Code rather than the standard zoning district land use table. The Downtown Code
 establishes district-specific standards that govern building form, site design, and development intensity
 in the central business district.

 Where a theater requires discretionary land-use approval in a particular zoning district, the review
 process allows the City to evaluate site-specific impacts, such as traffic circulation and compatibility
 with surrounding uses, and to impose conditions where appropriate. However, Nashville’s zoning code
 does not establish minimum spacing requirements between performance venues. Operational aspects
 of venue activity, including sound levels, hours of operation, alcohol service, and crowd management,
 are generally regulated through separate building, licensing, and public safety frameworks rather than
 through zoning separation requirements.

6. Seattle, WA
 Seattle regulates theaters and performance venues through defined use categories within its Land Use
 Code and through development standards applicable within specific zoning districts.

 The City’s zoning framework distinguishes among several theater- and assembly-related uses under the
 broader category of “Theaters and spectator sports facilities.” Subcategories include motion picture
 theaters, performing arts theaters, lecture and meeting halls, and spectator sports facilities. These
 defined use types are incorporated into the zoning code and are treated as distinct land use categories
 for regulatory purposes.

 Whether a theater or performance venue is permitted depends on the underlying zoning district. In
 commercial and downtown zones, theater and spectator-related uses are generally permitted, subject
 to the development standards applicable to the district. In other zones, discretionary review may be
 required depending on the classification of the use and the zoning designation.

 Seattle’s zoning code regulates several physical and site-related aspects of theater development. These
 include building height, bulk, setbacks, and floor area limitations based on the applicable zone. The
 code also establishes use-specific off-street parking requirements for certain theater and assembly
 categories, with parking ratios tied to the type of use. In higher-density urban centers and downtown
 districts, parking requirements may be reduced or modified.

 6


 Page 67
Planning Board Workshop – Performance Hall Regulations Case Study March 10, 2026




 Where discretionary land use review is required, the City may evaluate site-specific impacts such as
 traffic circulation, pedestrian access, and compatibility with surrounding uses and may impose
 conditions as part of the approval process. However, Seattle’s zoning code does not establish minimum
 spacing requirements between entertainment venues.

 Operational aspects of performance venues, including sound levels, hours of operation, and alcohol
 service, are regulated outside the Land Use Code through separate municipal noise regulations,
 building and fire codes, and state licensing requirements.

IV. OBSERVATIONS
Across the peer communities reviewed, performance venues are typically permitted within downtown,
commercial, or mixed-use zoning districts and are generally treated as compatible with higher-intensity
urban environments. In both mid-sized and larger cities, theaters and performance halls are regulated
primarily through use classification and district-based permissions that determine where such uses may
locate and whether discretionary land use review is required.

None of the jurisdictions reviewed rely on citywide minimum spacing requirements between performance
venues as a zoning mechanism. Instead, communities regulate entertainment uses through zoning-based
development standards, discretionary review in certain districts, targeted overlay provisions in areas
experiencing concentrated nightlife activity, and operational regulations addressing noise, occupancy,
alcohol service, and event management.

In larger cities with established entertainment economies, zoning frameworks distinguish among different
types of assembly and entertainment uses and regulate them through district standards and, in some cases,
downtown-specific zoning codes. In these jurisdictions, venue clustering in central areas is generally
managed through development standards and operational regulation rather than through spatial separation
between entertainment uses.

One peer community, Portsmouth, NH, applies compatibility standards that include buffers between
certain performance facilities and residential zoning districts. This approach differs from venue-to-venue
spacing and instead focuses on separation between entertainment uses and nearby residential areas.

HEDC Agenda Item #2: Review and recommendation of proposed Amendments to
Chapter 14 Land Use Code regarding the Buffer Zone for Large Performance Halls with
occupancy of 1,000 or more persons.

HEDC Meeting on February 3, 2026


This amendment to the land use code is intended to address widespread constituent concerns
regarding the spacing of large entertainment venues in our downtown area. This amendment
increases the buffer zone on the peninsula (zones B-3 and WCZ) for large entertainment venues–
defined as those with a capacity of over 1000 people – to 750 feet. In doing so, the hope is to
mitigate traffic snarls that are bound to arise from thousands of people arriving to and leaving
from multiple venues at the same time.

As Portland’s density increases, the choices we make today will be felt for generations to come,
and I believe that we as leaders must proactively ensure that we are using the power given to us
by our constituents to ensure that we are building a city that makes sense.

A. Executive Summary

Currently in the City of Portland, challenges associated with parking are among the most pressing and frequent issues
brought to the City by constituents. This study quantifies the present state of parking supply and demand in a study area
consisting of Downtown, the Old Port, the Central Waterfront, and the Eastern Waterfront. With continued
development expected in the next 10 years, the study also projects future parking supply and demand given approved
and likely development. The study area is show in Figure A1 below outlined in green, a one quarter mile buffer around
the study area is outlined in red.




 Figure A1: The Project Study Area

The study addresses five tasks: Task 1) Existing Supply and Demand analysis, Task 2) Projected Future Parking Supply and
Demand, Task 3) Strategy Recommendations, and Task 4) Implementation and Funding. Each task is described here with
a summary of the key results.

 Waterfront

Task 1: Existing Supply and Demand Analysis

An inventory of on-street, surface lot, and structured parking supply within the study area was created. The results are
shown in Table A1. The total parking capacity in the study area is 15,669 spaces. This represents the maximum available
parking capacity mid-day on a weekday. Because some off-street parking operators close during the evenings, overnight,
and on weekends; the maximum parking capacity does vary, reaching a low of approximately 12,300 overnight on
weekends. A detailed account of the pattern of supply variation by time of day and weekday versus weekend can be
found in Chapter D.

 Effective Capacity 2,916 3,258 1,645 2,027 1,387 935 1,822 13,990 1,176


In Table A1, the effective parking capacity, 13,990 spaces, is defined as the total of 90 percent of the structured and off-
street parking supply and 85 percent of the on-street parking supply. The effective capacity is a concept in parking
analysis that refers to the occupancy level at which parking users begin to have difficulty finding open spaces and vehicle
circulation to access parking begins to exhibit signs of congestion including queuing. The effective capacity is also
thought of as the threshold when a parking supply begins to be perceived by users to be full. If a parking supply reaches
total capacity, vehicles must queue or continue circling until occupied space is vacated.

Table A1 also shows that outside of the defined study area boundary within a one quarter mile buffer area, there is up
to an additional 1,176 spaces in effective parking capacity found in surface lots and structured parking that offer general
use public parking and may be used by travelers destined for the study area. The supply outside of the study area is
shared with land use outside of the study area. The parking demand generated by land use outside of the study area was
not calculated during this study, therefore the exact amount of unoccupied parking available within the quarter mile
buffer area for use by travelers to the study area is not known. It is estimated however, that several hundred spaces are
needed in the quarter mile buffer area to meet the demand of employee monthly parking within the study area. More
detail on the estimated supply and demand for monthly parking is presented in Chapter D.

Task 1 included an estimation of current parking demand. An observed parking occupancy survey was conducted on one
Thursday and one Saturday in December 2016. A sample of structured, surface lot, and on-street parking facilities were
observed through manual data collection and voluntary reporting by structured parking operators. Because the
observations were made during Winter, the observed parking occupancy results were adjusted for the peak Summer
season using supplementary data on seasonal variation in ferry passenger demand and data on seasonal tourism from
the Maine Office of Tourism.

Combining the observed occupancy results of the parking survey and adjusting for additional peak season demand using
supplementary data, the peak season weekday parking demand by time of day is shown below in Figure A2. The peak
occurs at 12pm when parking demand reaches 14,280 vehicles. The estimated peak weekday demand at 12pm is 290
vehicles above the effective parking capacity of the study area at that time.

 Figure A3: Estimated Peak Season Saturday Parking Demand by Time of Day

The results of the on-street parking occupancy survey individually show that during the weekday evening and on
Saturday after 1pm, on-street parking is likely at or over effective capacity in the study area. Effective capacity for on-
street parking is defined here as 85 percent of on-street spaces occupied. The implications of this finding are that at
times when there is parking availability in surface lots and structured parking, such as weekday evenings and on
Saturday, on-street parking is highly occupied and difficult for users to find. Findings on Portland’s on-street and off-
street parking pricing relative to peer cities are included in Chapter D.

Figures A4 and A5 show the observed Thursday and Saturday on-street parking occupancies for the overall on-street
survey sample. The Thursday results show an overall occupancy above 85 percent at 7pm only, however individual
streets varied and some high demand streets such as Commercial St, Middle St, and Exchange St exhibited higher
occupancy rates than the overall sample. A detailed account of the on-street parking occupancy survey results by street
and block face appears in Chapter E of this report.

A second method was used to estimate overall parking demand in the study area based on Land-Use. Parking generation
factors from the Institute of Transportation Engineers (ITE) and the Urban Land Institute (ULI) were used to create
estimates of weekday and weekend parking demand based on land-use data provided by the City’s tax assessor. The
results are shown in Figures A6 and A7 below. Weekday results show a peak parking demand at 2pm of 14,470 vehicles,
which is 480 vehicles more than the effective capacity at that time. Weekend results show two peaks, a recurring
parking demand peak between 12pm and 1pm of 9,390 vehicles, and an evening peak which would occur during a sold
out arena event of 10,350 vehicles.

 Figure A7: Land-Use Generated Parking Demand Estimate for a Weekend Day



A summary of the overall parking supply and demand findings are presented in Tables A2 and A3. The conclusion is that
at present, during the peak summer season on weekdays in the afternoon, parking demand in the study area is likely
between 290 and 480 vehicles beyond the effective parking capacity of supply within the study area. On Saturday’s
during the peak season, parking demand is well below effective capacity overall, yet on-street parking is over capacity
after 1pm as was shown in Figure A5.

Task 2: Projected Future Parking Demand

Future parking supply and demand 10 years from now is projected considering ferry passenger growth, tourism trends
to the Casco Bay Region, and three land use development scenarios that include newly build parking supply. Detailed
information on the methodology and development projects included in the projections appear in Chapter J. Figure A8 is
a map of included development projects in the analysis.




 Figure A8: Future Development Projects Included in the 10-year Future Parking Demand Analysis

The parking projections were created by adding the projected land use development to existing land use and applying
the same land-use based parking generation methodology as the existing conditions analysis. Three development
scenarios were considered, a full build-out, a scenario including all approved projects plus 75 percent of likely projects,
and a scenario including all approved projects plus 50 percent of likely projects. For the scaled down scenarios, newly
built parking was scaled down along with expected development. The population and employment implications of the
three scenarios in comparison to Portland’s comprehensive plan are discussed in Chapter J.

Tables A4 and A5 summarize the projected parking supply and demand of the future scenarios. On weekdays during the
peak season, the full build-out scenario is projected to result in parking demand that is 940 vehicles more than the
projected effective parking capacity of the study area. The approved plus 75 percent of likely projects scenario is
expected to result in parking demand that is 900 vehicles more than projected effective capacity, and the approved plus
50 percent of likely projects scenario is expected to result in a parking demand that is 840 vehicles more than projected

 Waterfront

effective parking capacity. On Saturdays during the peak season, all development scenarios are projected to result in
parking demand that is still below the effective parking capacity of the study area.

Based on the results of the future parking supply and demand projections, we recommend a planning goal of reducing
parking demand the study area by a range of 700-750 vehicles within a 10-year period. Parking demand should be
managed to be at or just under the weekday peak hour effective capacity of parking supply inside of the study area,
which is projected to be in a range between approximately 15,480 to 16,870 parking spaces depending on the future
development scenario.

Task 3: Strategy Recommendations & Task 4 Implementation and Funding

Reducing demand for parking does not mean reducing trips to the study area. A set of recommendations were
developed to use technology, emerging mobility on demand services, and enhancement of transit and bicycle
infrastructure to reduce reliance on the personal vehicle for transportation to the study area. The recommendations
also aim to provide options for better management of the City’s existing parking resources, as well as an enhanced user
experience. The specific parking challenges of employers, island residents, and low-wage earners are addressed in the
recommendations and explained in greater detail in Chapter K.

Local, state, and federal funding assistance for the parking demand reduction and management recommendations are
detailed in Chapter J. New sources of local funding include membership dues to a new transportation association, a
development impact fee, and a special purpose parking meter rate increase on high demand streets to fund targeted
programs. State funding was not found to be a likely source of funding with the exception of a possible contribution
toward a local match to leverage federal funding. Federal funding assistance is possible for a number of the
recommendations, and a discussion is included in Chapter J on relevant federal formula grants and competitive grants
for which the City of Portland or another eligible agency in the study area could create a proposal.

Table A7 lists the parking demand reduction and management recommendations along with a suggested timeframe of
implementation and suggested funding sources.

B. Existing Supply and Demand Analysis
B.1 Introduction
As Task 1 of The City of Portland Parking Study for the Eastern Waterfront & Old Port, Fort Hill Infrastructure conducted
an existing conditions analysis. Task 1 objectives included:

  Inventorying the existing parking supply within the study area,
  Collecting parking occupancy data on one weekday and one weekend day during the winter,
  Adjusting the collected parking data to represent the peak season,
  Conducting interviews with parking stakeholders,
  Identifying key parking issues related to employees of the study area, island residents, visitors, and study area
 residents,
  Identify subareas within the study area that may be experiencing more parking challenges than others.

B.2 The Study Area
The study area included what is generally considered Downtown Portland south of Cumberland Avenue encompassing
some of the Arts District, all of the Old Port, the Waterfront (referred to here as the Central Waterfront), and the
Eastern Waterfront. Figure 1 below shows the study area boundary. A one quarter mile buffer area boundary is shown
outside of the study area.

 Figure 1: The Study Area Boundary and Subareas

To allow for a more localized analysis in some sections of this report, the study area was divided into 7 subarea zones.
Table 1 describes the streets demarcating the subarea zones.

B.3 Employment
Employment growth in the Portland region and study area is considered here briefly to give a sense of the economic
climate in which this parking study occurred. Between 2002 and 2014, a period that included The Great Recession of
2007 to 2009, employment growth was modest in the study area with a compound annual growth rate (CAGR) of 0.7%
annually. During this 12-year period, employment growth in the study area slightly outpaced the City of Portland the
Portland Metropolitan Statistical Area (MSA)1. Between 2010 and 2014, post-recession, employment grew in the study
area at a faster CAGR of 2.2%. The rate of employment growth in the study area was, however, lower than the national
employment growth rate during the same period as shown in Table 2. The Peninsula refers to the area south east of I-
295.

The employment distribution among the subarea zones is shown in Table 3. Subarea Zone 4, in the Old Port, contains
the most jobs, over 25% of the total study area employment, and has the highest employment density of the subarea
zones at 144 jobs per acre. The subarea zones on the Central and Eastern Waterfronts currently contain fewer jobs,
however as a subsequent chapter will show, the Waterfront zones are expected to see significant employment growth in
the next 10 years.

In Table 4, the home zip codes of study area workers who live within the City of Portland give a sense that Portland City
residents who work within the study area are distributed roughly evenly among the City’s zip codes, with the exception
of zip codes covering the islands.

Of the workers who live outside of the City of Portland, Table 5 shows the top ten zip codes from which workers
commute. Any mobility solution for commuting workers to the study area should take into consideration where more
workers tend to begin their commute.

Figure 3 maps the zip codes shown in Table 5. The zip code boundaries are populated with dots representing workers to
give a visual sense of relative worker density, although the dots are distributed evenly in each zip code boundary and not
to actual worker home locations. South Portland, Zip Code 04106, and Westbrook, Zip Code 04092, stand out as
particularly important commuter markets for the study area located outside of the City of Portland due to their
relatively high density of study area worker homes.

B.4 Population
As shown in Table 6 , according to the 2015 American Community Survey 5-year sample, Census Tract 3 in Cumberland
County, which has a boundary that closely matches the study area, has a total resident population of 2,600. Since 2000,
the total population in the study area has decreased, evidently due to a significant drop in the population living in group
quarters, which includes group homes, institutions, shelters, etc. However, the number of occupied households in the
study area and the population living in occupied households has remained relatively constant in the last 15 years, as
shown in Table 7. In contrast, the Portland MSA gained population at a rate of nearly 7 percent during the same period.

The resident population within the study area is shown in Table 8. It shows that existing population within the study
area is heavily concentrated in Subarea Zone 1 with approximately 63% of the population. Subarea Zones 5, 6, and 7,
along the Central and Eastern Waterfronts currently have the fewest residents, however a subsequent chapter will show
that these zones are expected to see significant residential development in the near future.

B.5 Work Commute Travel Mode
To get a sense of commuting trends in the Portland region, journey to work data from the 2000 census and 2015 ACS 5-
year estimate were compared. The data describes how workers who live in a defined area commute to work collectively
to all jobs. It is not possible to exclusively isolate how those who work in the study area commute, as that information
would need to be extracted from a regional travel demand model or collected through a travel survey.

The data shows significantly lower shares of drive alone commuting for workers who live in the study area or on the
Peninsula as compared to the City and MSA. The share of workers who walk to work is very high in the study area at 43
percent in 2015, implying that those who live in the study area tend to work within a walkable distance from home.

Table 9 summarizes regional commuting trends between 2000 and 2015, the key insights are:

  The share of commuters who drive alone decreased in the region, and residents of the study area
 shifted away from driving alone more than the region with nearly a 9 percent decrease;


Fort Hill Infrastructure Page 21 of 179
 Page 94
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

  Carpooling decreased everywhere except with residents of the study area where the carpool mode to
 work rose by nearly 7 percent;
  Transit commute mode share appears to have decreased slightly for residents who live in the urban core
 of the Portland region, yet the region saw a very small 0.1% increase in transit ridership suggesting that
 commuters living outside of the City of Portland have accounted for the small regional net gain in transit
 commute share;
  Bicycle commute mode share increased on the Peninsula at just over 1 percent, yet residents of the
 study area appeared to be commuting by bicycle less in 2015 compared to 2000;
  Walk mode share increased everywhere with impressive gains of nearly 9 percent on the Peninsula and
 nearly 12 percent for residents of the study area;
  The share of workers who worked from home increased everywhere except for the study area, which
 saw a nearly 4 percent drop in the share of home workers.

B.6 Auto Ownership
Auto ownership trends between 2000 and 2015 in the Portland MSA looked more or less like the nation as a whole, with
growth in the number of vehicles available per occupied household of 3.3 percent in the Portland MSA versus 3.9
percent nationally. The City of Portland had higher growth in auto ownership than national and region rates with an
increase of 4.4 percent.

The urban core of Portland had slower rate of growth in vehicles per household during the 15-year period. Household
vehicle ownership rates on The Peninsula grew by a rate of 2.6 percent during the period while the study area grew at a
rather marginal rate of 1.1 percent. In 2015, Peninsula residents owned vehicles at a rate of 0.97 per household. Within
the study area, the rate was 0.7 vehicles per household, well below the national average of 1.76 vehicles per household
and the regional Portland average of 1.79 vehicles per household. It is interesting to note that while auto ownership
levels rose, commuting to work by single occupancy vehicle appears to have decreased in the Portland region over the
same timeframe. Table 10 shows the regional auto ownership trends normalized by occupied households.

C. Existing Parking Information Technology
Many cities are making detailed parking data available to users in real time. It is encouraging that the following
smartphone apps are either already available in Portland, or will soon be:

  Expected in the Fall of 2017, the new City of Portland Parking app that will allow for payment of on-street
 parking using a smartphone for the first time. Users will get updates on the app including alerts for expiring time
 and will have the opportunity to add more time up to the allowable limit. The app will be functional using both
 multi-space kiosk and traditional coin operated metered spaces. If over time the app can be enhanced to
 provide on-street occupancy and wayfinding to open on-street spaces, it could be helpful for Portland to dispel
 negative perceptions about parking availability. The new app along with the City’s new electronic enforcement
 technology should help the city better manage on-street parking supply.

  The Passport Parking app is used by the largest surface lot operator in the study area, Unified Parking Partners.
 The Passport app already informs users where to find surface lot space on a map of Portland, allows for price
 comparison, hourly or multi-hour parking purchasing, and the app interfaces seamlessly with Google Maps for
 wayfinding. The interface could be improved by displaying price information earlier in the transaction process to
 quicken price comparing and including information on real-time lot occupancy.

  Spare Spott is a parking app operating in Portland that allows commercial parking operators or commercial
 property owners to sell transient parking at underperforming locations that may have low visibility or are
 grouped in small numbers in “spare” locations. The app markets itself as a way for operators who do not have
 their own app to connect with customers and sell underperforming spaces. The app splits profit with the owner.
 Hourly prices are displayed on a map of Portland prominently, making price shopping easy upon fist opening the
 app. The company may raise or lower hourly rates based on demand every six months.

  ParkMe and Parkopedia are global parking apps and websites that began as mostly informational but are
 evolving into full service parking apps as more operators share real-time information and partner with them to
 allow reservations. Substantial information on parking facility operating hours, prices, and facility size, and
 wayfinding is currently available for Downtown Portland using both apps. A limited number of parking operators
 currently allow the purchasing of parking using the apps. ParkMe also provides real-time occupancy at
 structured parking facilities, and in some markets, such as Washington, DC, the coverage of occupancy data at
 downtown garages is impressive. Currently, just one floor of the One City Center Garage in Portland appears to
 provide real-time occupancy information to the ParkMe app. With more parking operator partnerships, these
 apps could become excellent tools for prospective parking users.

D. Existing Parking Supply
D.1 Structured Parking Supply Inventory
Structured parking garages were inventoried in the study area using existing City parking survey data, supplemental
aerial imagery, and information from City staff. The parking structures shown below in Figure 4 are categorized as either:

Public Use- Daily general purpose public parking use including monthly and transient users. Blocks of passes may be held
by employers and or hotels/business for customers. Allocation of space to monthly pass holders and transient users is
typically managed in real time with the help of software.

Private Commercial- Parking reserved for the employees and customers of commercial tenants in attached or nearby
buildings.

Private Residential- Parking reserved exclusively for residents of attached or nearby buildings.

Private with Limited Public Use- Parking reserved for private tenants of attached or nearby buildings with some
allowance for general use public parking either through monthly parking passes or limited transient hours typically
during off-peak periods.

An inventory of the number of parking structures by subarea zone and primary use is shown in Table 11. The land area
consumed by structured parking is included. Where a parking structure fit within the structural footprint of a
commercial or residential structure, the land area was not counted. This exception does not include parking structures
with ground floor retail. Two public use garages within the quarter mile buffer area surrounding the study area are also
included.

Structured parking capacities are summarized in Table 11. The Downtown/Old Port contains the most structured parking
in the study area, with Subarea Zones 1 and 2 containing just over half of the structured parking. Total structured
parking capacity totals 7,013 spaces with 87% percent of total spaces (6,113) located in garages operated for public use.
There are an additional 1,050 structured parking spaces outside of the study area north of Cumberland Avenue within
the quarter mile buffer area. Effective capacity is defined as 90 percent of total capacity, which is the maximum
occupancy level attained before users have high difficulty locating spaces and queuing begins to occur in and around the
facility.

D.2 Structured Parking Monthly Supply and Pricing
The exact number of monthly spaces sold at privately operated garages is considered confidential information and was
not shared by operators for this study. The amount of monthly parking offered is sometimes set by lending terms.
Parking operators set their rate structures and parking mix (monthly vs. transient) to maximize revenue. Transient
parking users pay a higher daily rate but can be a less reliable source of revenue. Many structured parking operators use
software to optimize the parking mix offered. The amount of monthly parking available to employees in the study area is
among the most important parking issues Portland is facing, as employers have voiced frustration over the scarcity of
monthly parking for new employees.

Table 13 shows what the quantity of monthly structured parking would likely be under a range of reasonable
assumptions for different types of structured parking.

For the public use structures, a low range of 65 percent and a high range of 85 percent of total capacity for daytime
monthly parking was assumed, including an oversell rate of 10 percent. Oversell rates are possible because of the daily
probability of monthly parker absenteeism, vacation, and time differences in worker shifts. Reserved parking is not
typical in Portland except for in private commercial and residential garages. Monthly supply in private commercial
garages was estimated as the total capacity since these structures are primarily built to accommodate the employees of
attached structures.

Garages primarily for hotel patron use were estimated at 15 percent to 20 percent monthly. Although residential parking
structures do not typically contract out monthly parking for nearby employees, an estimated 12 percent of structured
residential spaces are counted towards monthly parking capacity because it is unlikely that residents who both live and
work within the study area would pay to re-park their vehicles at their place of employment. The 12 percent estimate is
derived from dividing the number of primary job holders who both live and work in the study area, 3002 by the adult
population of the study area, 2,4313.

Also in Table 13 are average monthly, daily, and hourly parking prices for structured parking. The average prices in each
zone were weighted by garage size. The highest average parking rates are found in Subarea Zone 4 in the Old Port,
Subarea Zone 6 near the Casco Bay Lines Ferry Terminal, and Subarea Zone 7 the Eastern Waterfront.

To put the average structured parking prices into context, Table 14 was made to show how average prices from the
study area compared to other cities in New England. As a quick way to aggregate price data from other cities, the online
parking information from site Parkopedia.com was used to retrieve parking prices from the 5 closest parking structures
to City Hall in each of the respective cities. The averages shown are weighted by structure size where possible and
reflect weekday prices.

Portland appears to be middle of the pack compared to other New England cities by monthly and hourly prices for
structured parking. Daily structured parking prices, however, show that Portland is second only to Boston in average
price.

In some markets, garages offer evenings-only monthly parking at reduced rates, however the practice does not appear
to be widespread in the Portland. One garage in Subarea Zone 4 advertises monthly evenings-only parking at a cost of
$85.

D.3 Surface Lot Parking
Surface parking lots were inventoried in the study area using existing City parking survey data, supplemental aerial
imagery, and information from City staff. The surface lots in Figure 5 are categorized by their primary use as either:

Public Use- General purpose public parking use. Payment structure may either be by monthly permit, daily, hourly or
some combination thereof. Public use lots may be publicly or privately owned.

Private with Limited Public Use- Private lots primarily for employee or customer parking that offer limited general-
purpose public use either through the sale of a limited number of permits for weekdays or off-peak transient access.

Private Commercial- Parking intended for use by the customers of nearby commercial land use, possibly with limited
employee parking mixed in.

Private Residential- Parking reserved exclusively for residents of nearby buildings.

Private Employer- Parking reserved for employee or industrial parking use.

Private Shared/Other- Parking that serves a mix of nearby land uses including residential, commercial, and or
civic/ecclesiastical/institutional use. General public parking is not allowed.

Figure 5 also includes a small number of surface parking lots located outside of the study area that are known to offer
general purpose public parking. There are many more private surface lots within the quarter mile buffer area, but most
serve businesses and residences outside of the study area.

parking, which was 2.9 percent (as shown in Table 11), the total land area allocated to parking in the study area
becomes 21.8 percent. To put the percent of land area devoted to parking in the study area into perspective, Table 16
shows central business district land area allocated to off-street parking from past studies of other cities. The study area,
which is a close proxy for Portland’s CBD, is among other CBDs known to have a high percent of land area allocated to
surface parking.

spaces with 43 percent of total spaces (2,785) designated for public use. There are an additional 316 spaces outside of
the study area identified as offering public parking. Effective capacity is shown as 90 percent of total capacity, which is
the maximum occupancy level attained (5,765 spaces) before users have high difficulty locating spaces and queuing
begins to occur in and around the facility.

D.4 Surface Lot Monthly Supply and Pricing
An estimate of monthly surface lot parking supply (available during the daytime) was made using the following
assumptions. Public use lots that advertise as monthly parking only during weekday working hours are known. Public use
lots that offer a mix of monthly, daily, and hourly parking where the number of monthly parking spaces sold was
unknown were assumed to offer a range between 65 percent and 85 monthly with an oversell rate of 10%.

Private employer lots were considered to be 100% monthly. Private commercial lots are primarily for customers,
however 25% was counted as monthly to account for limited parking for business owners and employees who may have
close parking privileges. Similarly, a 25% assumption was also made for shared/other parking lots. Private residential
parking lots were counted as 12% monthly parking, based on the percent of adult study area residents who also work in
the study area and would be unlikely to repark their vehicle at work.

Table 18 shows the estimated range of monthly parking by subarea zone. Also in Table 18 are surface lot weighted price
averages. Price averages were weighted by lot size. A separate average was calculated for weekend prices because some
private lots offer public daily and hourly parking on weekends only. The average daily weekend rate was slightly lower,
$21 compared to $23, on weekdays. The average weekend hourly rate was slightly higher at $3.75, compared to $3.25
on weekdays. Additionally, a limited number of lots offer a flat evening rate after 6pm at an average of $5.

Comparing the study area surface lot prices to other cities in New England shows that the monthly and hourly surface lot
prices fall near the middle of the pack in New England, but the daily surface lot price of $21 ranks third behind Boston
and Portsmouth, NH. Table 19 contains a surface lot price comparison. The data from other cities was collected by
averaging prices at up to 5 of the nearest surface lots to each respective city hall using the parking information site
Parkopedia.com and supplemental information from individual city websites.

Portland charges $1.25 per hour for on-street parking, a rate comparable to other medium to large New England cities.
As Table 21 shows, where other cities have raised rates higher than a $1.25 per hour, they have also typically introduced
some type of price variability by location with higher rates in higher demand areas.

D.6 Total Study Area Parking Supply
Combining the structured, surface lot, and on-street parking supply in the study area gives the total parking capacity
shown in Table 22. The study area capacity comes out to 15,669 spaces with an effective capacity of 13,990 spaces
which is the state at which all structures and surface lots are both 90% full and on-street parking is 85% occupied. The
total estimate of monthly parking comes out to a likely range of between 8,730 and 10,750 monthly spaces, which is 65
percent to 80 percent of the total off-street supply in the study area.

 Parking


In the sections that follow, observed parking occupancy and a land-use based parking analysis estimates overall parking
demand in the study area. However, neither of these methods could isolate monthly parking demand from transient
demand. A quick approximation of monthly demand from employees in the study area is made using a combination of
the employment from Table 3, the commuter mode share data from Table 9, and the estimated supply of monthly
parking in Table 22.

The results in Table 23 place the demand for monthly employee parking in the study area about 320 spaces above the
high range estimate for monthly parking supply in the study area. After including the estimated monthly parking supply
in the quarter mile buffer area as available to study area workers, the total monthly supply within walking distance to
the study area is about 800 greater than the demand. The monthly parking demand from employees who work outside


Fort Hill Infrastructure Page 37 of 179
 Page 110
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

of the study area but within the quarter mile buffer area was not calculated, however these employees surely take up
some of the monthly supply in the buffer area, although it is more common for employers outside of the study area to
provide on-site parking. This approximation is not precise enough to produce a definitive number of additional monthly
supply needed. There are also island residents who also purchase monthly parking at and near the ferry terminal.
Overall monthly parking demand per day is probably within a couple of hundred of the total monthly supply within a
walkable distance of the study area. Unrestricted on-street parking in the study area and in adjacent neighborhoods is
also likely being used by full-time workers given the tight market for monthly parking.

Based on Table 23,
Figure 6 shows which subarea zones likely generate more monthly parking demand than the high estimate of monthly
parking supply in each zone. Subarea Zones 1, 3, and 4 have more employee demand for monthly parking than available
supply in those zones respectively. Employees of these zones are likely parking in adjacent zones with available monthly
parking where available.

E. Observed Parking Occupancy

Parking occupancy data was collected at a sample of garages, surface lots, and on-street sites simultaneously on
Thursday, December 1st, 2016 and Saturday, December 3rd, 2016.

The weather on the Thursday sample date was 36 degrees and had a light drizzle of rain until 9am before overcast skies
stabilized. The Saturday sample had a temperature of 40 degrees with intermittent clouds and sun. The choice of early
December for collecting the data was more of a project timeline necessity than a first choice, but as shown in the
seasonal factors section, the sample days appear to have had higher than average, but not annual peak demand.
December is near the annual low in visitors to Portland from outside of the region. This issue is addressed in the
seasonal factors section where the observed parking occupancy is adjusted for the peak season.

The occupancy data presented in this section shows the amount of vacant space observed without adjustment for how
the vacant space is managed. Almost all of the structured parking operators in the study area manage their facilities with
software to maximize the amount of vacant space that may be sold to transient demand at a certain time of day. Surface
lots in Portland tend to be operated more manually. For surface lots that are managed in a way that does not allow for
optimal resale of vacant space to transient users, there may be fewer available spaces for resale than observed


12
  The large decrease in parking between 3pm and 5pm on Saturday resulted from The One City Center Garage closing at 4pm and
the Cumberland County Courthouse garage closing at 5pm when this parking capacity analysis was completed. However, the
operating hours of Th One City Center garage (600 spaces) has since changed to 24 hours a day and 7 days per week.

Fort Hill Infrastructure Page 42 of 179
 Page 115
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

occupancy would suggest. As shown in Table 23, the daily average rate of absenteeism and vacation use for American
workers is about 10%. Additionally, some monthly parking users may leave during the day for appointments etc. As a
result, operators might oversell their target share of monthly parking based on their experience with the daily use rates
of monthly parking. We have not factored up the observed occupancy rates to address monthly parking user vacancy,
because making efficient use of that vacancy can be maximized with optimal parking management, and it is important to
know the observed amount of vacant space so that the efficiency of parking supply management might be known in
cases where parking is said to be unavailable but vacant spaces exist.

E.1 Observed Surface Lot Occupancy




  (Figure 5 from Section D.3 repeated here for reference)

As described in the section on garage and surface lot supply, there are 90 surface lots containing 6,405 spaces in the
study area. On two data collection days, the surface lot occupancy data was manually collected by a team of observers
every two hours. The Thursday count intervals began at 8am and concluded with a final count interval at 8pm. On
Saturday, the counting began at 10am and concluded at 8pm. Between 60 and 77 lots were captured in the sample
depending on the hour, and the coverage was well distributed across the study area.




Fort Hill Infrastructure Page 43 of 179
 Page 116
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

Off-street parking is considered effectively full when it reaches 90 percent occupancy because that is the occupancy
level beyond which the facility is perceived as full by users. The short-term rise and fall of occupancy level due to
turnover needs a 10 percent reserve capacity to prevent intermittent queuing in and around the facility.

For the study area on Thursday, a single peak was observed during the middle of the day. The peak average surface lot
occupancy of 72 percent was observed at 12pm, and the observation at 2pm of 70 percent was nearly as high.
Occupancy dropped steadily after 2pm to a low of 19 percent by 8pm.

Figure 9 shows a chart of average surface lot occupancy for the study area for the Thursday sample. As a measure of
dispersion in the sample of surface lots, the bars represent one standard deviation from the mean, which tended to be
about +-22 percent.

E.2 Observed Structured Parking Occupancy




  (Figure 6 repeated here for reference)

As described in the section on structured parking inventory, there are 21 parking structures containing 7,013 spaces in
the study area. Eight parking structures are for private use only, four serve office employees in attached structures,
while four are used by attached residential developments. The observed occupancy results here focused on the 13
parking structures that offered at least some public parking with a total of 6,308 spaces.

Automated entrance/exit data was requested from structured parking operators on Thursday, Dec. 1st and Saturday,
Dec. 3rd. Data was received for 9 parking structures with at least one structure in each subarea zone. Data from a 10th
structure was collected manually on-site during the data collection days.

Structured parking is considered effectively full at 90 percent occupancy. The Thursday and Saturday weighted average
occupancy data are displayed in Figure 13 and Figure 14 respectively. Average occupancy was weighted by garage size.
The standard deviation bars give a sense of the range of occupancy levels found among the different parking structures
by time period.

The Thursday results showed a single peak mid-day with a high of 72 percent between 12pm and 2pm. One standard
deviation from the mean during the peak period was about 12 percent.

Individual garages are not shown for commercial privacy considerations, but one garage had to be displayed separately
because it is an important outlier. The Casco Bay Garage is an ‘upside down’ garage meaning it peaks in occupancy
opposite of the usual mid-day peak. The Casco Bay Garage showed a peak occupancy of 72% between 12am and 6am.
The garage is known to have customers who live on islands in Casco Bay and commute daily to and from the island using
a parked vehicle at the garage.




 Figure 13: Thursday Observed Occupancy at Structured Parking for Public Use




A quick look at the variation within the study area of structured parking occupancy for the Thursday sample shows that
for the period between 10am and 2pm, Subarea Zone 4 and Subarea Zone 2 both in the Downtown/Old Port had higher
average occupancy than the study area, when not including the Casco Bay Garage. Table 24 shows average subarea
zone occupancies during the mid-day period ordered from highest to lowest on the observed Thursday.

Results from the Saturday sample showed low structured parking occupancies across the study area except for the Casco
Bay Garage as shown in Figure 14. The Casco Bay Garage had occupancies ranging between a low of 66 percent at 9am
to a high of 80 percent at 5pm. The weighted average occupancy for all other sampled parking structures peaked
between 1pm and 3pm at about 17 percent, one standard deviation from the average during the peak period was about
9 percent.

A quick look at the variation within the study area of structured parking occupancy for the Saturday sample shows that
for the period between 1pm and 3pm, the afternoon peak period, Subarea Zone 3 in the Downtown/Old Port and
Subarea Zone 7, the Eastern Waterfront, had slightly higher than average structured parking occupancy than the study
area, in addition to the Casco Bay Garage in Subarea Zone 6. Table 25 shows subarea zone occupancies during the

E.3 On-Street Parking: Overall Occupancy
On-street parking data was collected on the sample dates (Thursday Dec. 1st and Saturday Dec. 3rd) from selected streets
in the study area including: Commercial St, Spring St, Middle St, Exchange St and Casco St. Observations were made at
one-hour intervals beginning at 8am and ending after 8pm. An observer walked along each side of the street and
recorded the last 3 digits of parked vehicle license plates allowing for analysis of both occupancy, duration, and
turnover. Metering in the 2-hour zones was in effect between 9am and 6pm on Thursday and Saturday. The total
number of 2-hour metered spaces sampled was 477 representing about one third of the 1,485 two-hour metered spaces
in the study area. Figure 15 shows the on-street sample coverage area.




 Figure 15: The On-Street Parking Sample


The focus in this section is on occupancy in the 2-hour metered zones. On-Street parking is considered effectively full at
85% capacity. Beyond this level, users have difficulty finding parking on the street and either give up or circle the block
repeatedly leading to user frustration, increased traffic, and the perception that there is no parking.

Study area wide, the Thursday results show a pattern of rising occupancy in the morning to about 80 percent by noon.
Between noon and 3pm, occupancy moved between 75-80 percent. After 3pm, occupancy began to climb and reached a
peak of 87 percent at 7pm before trending down to 77 percent by 8pm. The 7pm observation interval was the only one

 Page 125

 Waterfront

on Thursday to show that the aggregate on-street sample was effectively full, though as subsequent sections show,
variation existed block to block. Figure 16 shows the percent of 2-hour metered spaces occupied between 8am and 8pm
for the study area sample on Thursday.

 Figure 16: Overall Thursday 2-Hour Metered Occupancy



The Saturday results show higher on-street occupancy than Thursday. Overall 2-hour metered occupancy rose steadily
to an effectively full level of 88 percent by 2pm before decreasing slightly below 85 percent through 3pm. After 3pm,
overall occupancy surpassed the effectively full level again and steadily climbed to a peak of 97.5 percent by 8pm. Figure
17 shows occupancy between 10am and 8pm for Saturday. It should be noted that the increasing occupancy trend
leading to the second peak of the day begins close to 4pm. That is the time when a vehicle may park, pay for two hours
until the metered period ends at 6pm, and then remain for the rest of the evening.

E.6 On-Street Parking Duration and Turnover in 2-Hour Metered Zones
Parked vehicle duration and turnover are important metrics to understand parking behavior. When on-street parking
occupancy is high, it is more desirable for parking turnover to also be high so that users have a greater chance of finding
an open space. When the observed data for this study was collected, in December of 2016, the City of Portland’s on-
street meter fee was $1 per hour for 2-hour limited zones. The hourly fee and time limit aim to facilitate parking
turnover between 9am and 6pm Monday through Saturday.

Average on-street parking duration and turnover by block face was calculated between 8am and 6pm for Thursday and
Saturday using observed partially recorded license plate data. Because the observation intervals were 1 hour apart, an
assumption had to be made about observed vehicle duration. If a vehicle was observed only once on a block-face it was
assigned a duration of 0.5 hours. A vehicle that was observed for exactly two count intervals on a block-face was
assigned a duration of 1.5 hours. Exactly 3 observations and the vehicle was assigned a duration of 2.5 hours, and so on.
The average parked vehicle duration for each block face was calculated using the formula

 ∑ ( )
 D=



Where D = average parking duration, h/veh;
 Nx = number of vehicles parked for x intervals;
 X = number of intervals parked;
 I = length of the observation interval, h;
 NT = total number of parked vehicles observed.

The average turnover rate for parked vehicles follows as the inverse of average duration. In Figure 41 and Figure 42, the
average parked vehicle durations by block-face are shown for the Thursday and Saturday samples.

The results show that on both Thursday and Saturday, the block-faces on Exchange St and Middle St had a lower parked
vehicle duration and higher turnover rate compared to Casco St and Spring St. This is a positive sign given that Exchange
and Middle St had some of the highest rates of parking occupancy.

Commercial St shows more of a range of parking durations by block-face which tended to be 1 to 2 hours closer to the
center of the Old Port on Thursday while block faces west of Cross St (north side of the street) and east of Franklin St
had an average parking duration under 1 hour. On Saturday, average durations on Commercial St tended to be higher,
between 1 and 2 hours on the north side of the street throughout.

There is one block-face on Commercial St west of Center St (south side of the street) that had unrestricted angled
parking on the observation days. The unrestricted parking was also observed in an adjacent bus loading zone to this
block-face, presumably because it was not bus tourist season. This was the location of the longest on-street parking
duration observed in the study area. On Thursday, this block-face had an average parking duration of just over 5 hours
per vehicle between 8am and 6pm which is a turnover rate of less than 0.2 vehicles per hour. On Saturday, the duration
was just over 2.5 hours per vehicle, a turnover rate of 0.4 vehicles per hour. This example illustrates how the metered
and time limited block-faces maintain a higher turnover rate compared to unrestricted and free on-street parking.

F. Summary of Observed Parking Results
In this section, the observed occupancy rates from the structured, surface lot, and on-street samples are projected onto
the total parking supply in each respective category to estimate the total number of occupied spaces between 8am and
8pm. The results presented in this section have not yet been adjusted for seasonality. Table 26 summarizes the Thursday
observed occupancy rates by hour.

Figure 43 displays the projected parking occupancy in the study area based on the Thursday, December 1st
observations. Private use only structured parking is displayed as 100 percent occupied since the spaces are reserved and
are not resold to the transient public even when vacant. The effectively full level of vehicles for the study area
represents the capacity when the surface lots and structured parking are 90 percent occupied and the on-street supply
is at 85 percent occupied. The Thursday peak occurred at 12pm when an estimated 11,560 spaces were occupied leaving
about 2,450 vacant spaces below the effective capacity of 14,011 spaces.

Projected results from the observed Saturday had a peak of approx. 6,200 parked vehicles at 2pm leaving about 7,300
vacant spaces before the effective capacity of 13,525 is reached.

Looking in more detail at the distribution of the observed vacant space, the next two figures show how many vacant
spaces remained before the effectively full level was reached in each subarea zone at the peak hour. In Figure 45, we see
that during the peak hour of 12pm on the observed weekday, Subarea Zone 1 had the highest number of vacant spaces
particularly on-street spaces and structured spaces. On-Street spaces in Subarea Zones 2 and 4 were above 85 percent
occupied during the peak hour, therefore no on-street vacancy is shown for those zones. Subarea Zone 7, the Eastern
Waterfront had the most vacancy in surface lots at the peak hour.

It is likely that not all of the observed vacant spaces were available for use depending on off-street parking
management. While garages use a computer to minimize vacant space that must be held for absent monthly customers,
some surface lots that are operated more manually may hold more vacant space open for absent monthly customers,
although holding more vacant monthly spaces open than necessary is not in an operator’s best interest.

During the observed peak hour on Saturday, there were many more overall vacant spaces observed due to higher
vacancies in structured and surface lot parking. However, the peak hour on Saturday had far fewer vacant on-street
spaces before the effectively full level of 85 percent occupancy. The only subarea that had less vacancy during the
Saturday peak hour compared to the Thursday peak hour was Subarea Zone 6 surrounding the Ferry Terminal on the
Waterfront.

The vacant space charts are useful to understand where additional transient parking demand during the peak season
might be accommodated within the study area.

G. Seasonal Analysis
In this section, the observed parking demand data is compared to annual parking demand curves at two sample garage
locations to determine if the sampled days in December were a good representation of recurring regional demand,
parking demand from seasonal variation in island ferry ridership is analyzed, and additional parking demand from higher
levels of day visitors and overnight visitors during the summer season is estimated using data from the Maine Office of
Tourism.


G.1 Recurring Regional Demand
Because the data collection occurred in December, it is important to look at the results in the context of parking demand
from other times during the year. Data on customer entrance and exit volumes annually is not usually disclosed by
private parking operators because the information is related to revenue. Data from the two publicly operated garages in
the study area, Elm St and Spring St, are analyzed here to put the observed results from the December sample days into
an annual context. Based on the location of the Elm St and Spring St garages, both are located in the north-west
quadrant of the study area, it is likely that annual demand patterns at these garages are better indicators of recurring
employment, retail, arena event, and restaurant related parking demand, rather than seasonal demand related to
waterfront tourism and ferry passenger activity.

Data from the year prior to this study at the Elm St and Spring St garages were obtained. Figure 47 shows the December
1st daily parking demand with other Thursday demand levels during the year at the Elm St garage. The December 1, 2016
daily demand fell at the 81st percentile of Thursdays, well above the median (50th percentile) peak demand for Thursday.

 Figure 48: Recent Thursday Demand Variation at Spring St Garage



The same comparisons were made between the Saturday, December 3rd observations at Elm St and Spring St using
annual Saturday data at each location. Figure 49 shows that the Elm St garage sample on December 3rd fits in near the
85th percentile of Saturday parking demand in the past year at that location. In Figure 50, however, we see that the
December 3rd data at the Spring St garage is very close to the 50th percentile Saturday demand at that location. The
observation day did not include an arena event and this is likely the reason for the observed demand at that location
placing close to the median. The highest demand on Saturdays at Spring St appears to correspond with arena events
during the year.

Based on the annual trends at Spring St and Elm St, we conclude that the December sample days were very likely a good
representation of average to higher than average recurring regional parking demand in the study area based on the
location of these garages.

It is interesting to note that both Elm St and Spring St garages appear to show lower demand for parking during July and
August, when a higher percentage of office workers and educators would be expected to be on vacation. It does not
appear that Elm St and Spring St attract a high volume of tourism parking during the summer. We were unable to
investigate the annual trends at other privately-operated garages because operators typically do not share annual data.
Further data collection in the summer season would be useful to determine whether other garages and lots see a
downturn in recurring employee parking during the summer and also to find out which facilities are attracting peak
season visitor parking demand.

G.2 Seasonal Variation in Island Resident and Island Visitor Parking
In this section, an estimate of additional peak season parking demand in the study area associated with island ferry
passenger activity is made using passenger data from Casco Bay Lines, employment data, and assumed automobile
mode shares.

The City of Portland’s Waterfront is home to the Casco Bay Lines Ferry Terminal, which serves as a vital transportation
hub for residents of and visitors to several islands in Casco Bay including Peaks Island, Little Diamond Island, Great
Diamond Island, Cliff Island, and Long Island. The parking garage located at the ferry terminal is known to house the
vehicles of many island residents and a waitlist estimated at several years long exists for the opportunity to purchase
monthly parking there. Island residents with a residential sticker from the City may also park in designated non-metered
(but time limited) zones located on the Eastern Waterfront for days at a time, although finding an on-street space has
become more difficult for islanders as development has occurred on the Eastern Waterfront. Additionally, island
residents and visitors to the islands may purchase parking at other structured and surface lot facilities in the study area,
if and when available.

For context, according to 2015 American Community Survey estimates, the island communities served by the Casco Bay
Transit District have a year-round resident population of 1,258 people living in 589 year-round occupied households.
Year-round island residents own 744 vehicles in total. The number of year-round island households owning at least one
vehicle was 400. During the peak Summer season, the number of occupied households increases to 1,803. The ACS does
not estimate seasonal population or seasonal vehicle ownership.

Available data describing travel to and from the islands consists of Casco Bay Lines ferry passenger monthly totals, on-
board vehicle transport monthly totals, and worker flow data between the mainland and the islands for primary job
holders. Ferry passenger volume variation is highly seasonal, the summer season is much higher than the rest of the
year. Figure 51 shows the trend of average daily passenger and on-board vehicle volumes by month for the most recent
year available.

 Source: Casco Bay Lines, 2016 monthly passenger and vehicle data. *November and December data are from 2015 as 2016
 data for those months was not yet available at the time of the data request.

According to Longitudinal Employer-Household Dynamics (LEHD) data from 2014, the most recent year available, the
number of workers who live on an island served by a Casco Bay Lines Ferry and hold a primary job on the mainland is
approximately 550. Additionally, the number of workers who live on the mainland but hold a primary job on one of the
islands totals approximately 100.

Subtracting the expected number of commuting workers to and from the islands from the average daily passenger totals
for a given month leaves a remainder of passengers that consists of visitors, full-time island residents making non-work
trips, and seasonal island residents (depending on the month). Table 28 shows the difference between August and
December passengers after subtracting out the expected number of recurring work commute trips.

To estimate the vehicle parking demand on the mainland associated with the August and December ferry passenger
demand, some assumptions need to be made about how workers and non-workers travel to and from the ferry
terminal. The following assumptions are made in the absence of more specific data on travel behavior to and from the
islands particularly for non-work trips:

  Of the approximately 550 island resident workers who commute to the mainland, employment data shows that
 approximately 100 of these workers work in the Downtown/Old Port. It is assumed that these commuters by
 and large do not drive between the ferry terminal and their work destination.
  For the remaining 450 island resident workers, a drive mode share equivalent to the City of Portland’s for work
 trips is assumed for travel between the ferry terminal and their work destination. The City’s rate in 2015 was 73
 percent drive alone, and about 9 percent carpool consisting of parties between 2 to 4 people.13
  For the approximately 100 workers who commute from the mainland to the islands, the City of Portland’s drive
 alone and carpool to work mode shares are also assumed.
  For all other passengers including visitor trips, year-round island resident non-work trips, and seasonal island
 resident trips, it is assumed that average travel party size is 2.5, which was the average travel party size for day
 visitor parties to the Portland region in 201514. A drive mode share of 82 percent is assumed based on the total
 automobile mode share of work travel in the City of Portland in 2015 in lieu of more specific data.

Applying the stated assumptions, an estimate for parking demand in the study area arising from ferry passenger activity
is presented in Table 29. The average daily number of vehicles transported round trip on-board the ferry is subtracted
from the estimated parking demand since those vehicles traveled with the passengers rather than remaining parked in
the study area.

City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

The net additional 770 vehicles are added to the observed demand from December as a seasonal adjustment to the
peak season for increased ferry parking demand. Because the passenger data from Casco Bay Lines does not give
weekday vs. weekend variation in passenger demand, the average of 770 additional vehicles are added to both weekday
and Saturday peak season estimates.

In addition to the Casco Bay Lines, the Eastern Waterfront hosts the international ferry to Nova Scotia that operates May
through October. Based on average daily passenger data from 2014-2016, an average daily walk-on passenger total is
25. It is estimated that parking demand related to the walk-on passengers is 10 vehicles, raising the peak adjustment for
combined ferry parking demand to 780 vehicles.

It is assumed that the impact of the additional 780 parked vehicles in the peak season would be allocated to the subarea
zone of the Ferry Terminal, Subarea Zone 6, and then to the Eastern Waterfront, Subarea Zone 7, following that to
Subarea Zones 4 in the Old Port and Subarea Zone 5 on the Central Waterfront, which are adjacent to Subarea Zone 6.

It is clear that added parking demand of approximately 780 vehicles from the increase in seasonal ferry ridership alone
could consume most of the off-street December observed vacant parking spaces shown in Figure 45 for the following
zones: Subarea Zone 6 (200-225 spaces), Subarea Zone 7 (400-425 spaces), Subarea Zone 4 (125-150 spaces), and
Subarea Zone 5(125-150 spaces) which collectively had about 850-950 vacant off-street spaces at 12pm on a December
weekday.

G.3 Summer Day Visitor Parking Demand Adjustment
A seasonal adjustment is estimated to account for the additional day visitor parking demand in the study area expected
during the peak summer season. Detailed survey data commissioned by the Maine Office of Tourism are used to create
the estimate. In the surveys, a day visitor to the Portland/Casco Bay region is defined as a traveler who originated within
the state of Maine or from up to 100 miles from Maine’s borders and traveled more than 50 miles from home to reach
their destination. Day visitor trip purposes included leisure, visit friend/relative, and business. The average weekday and
weekend day visitor parking demand to the study area is estimated for both the winter and summer seasons for the
purpose of understanding the difference. The percentage of day visitors who reported visiting Peaks Island (7 percent)
was subtracted from the adjustment so as not to overlap with the seasonal ferry passenger demand adjustment.

Several assumptions were made where specific data was not available. The automobile share of day visitor parties to the
study area is estimated to be 93 percent. The automobile mode share of overnight visitors was between 81-93percent15.
It is assumed that day visitors would have less time to travel by train or airplane, and therefore would be likely to drive
at a rate closer to the high estimate for overnight visitors.

It is assumed that the volume of day visitors is on average 15 percent greater on weekend days as compared to
weekdays. This is in keeping with tourism markets where leisure travel is dominant. Table 30 summarizes the derivation
of estimated day visitor parking demand to the study area for the winter and summer seasons. The result is an
estimated additional 1,710 vehicles on a peak season weekday and an additional 1,960 vehicles on a peak season
Saturday.

G.4 Summer Overnight Visitor Parking Demand
In this section, a seasonal adjustment is estimated to account for the additional overnight visitor parking demand in the
study area expected during the peak summer season. The methodology uses a combination of published hotel
occupancy rates in Portland for 2016, seasonal variation in statewide hotel occupancy rates, and Institute of
Transportation Engineers (ITE) parking generation factors for urban hotels. The percent of overnight visitors (7 percent)
who reported visiting Peaks Island in a survey commissioned by the Maine Office of Tourism20 was subtracted because
they are already captured in the seasonal ferry passenger parking demand adjustment.

Table 31 summarizes the derivation of the peak season overnight visitor parking demand adjustment. The result is an
additional 260 vehicles on a peak season weekday and 400 vehicles on a peak season Saturday.

G.5 Adjusted Seasonal Demand
Combining the demand curves from the observed December sample in Section E with the estimated adjustments for
peak season ferry travel, peak season day visitors, and peak season overnight visitors, a new adjusted estimate of peak
season weekday parking demand is produced as shown in Figure 52. The peak season adjustments result in a parking
demand that is higher than effective capacity between 12pm and 2pm on weekdays. Peak vehicle demand is estimated
as approximately 14,300 vehicles, which is approx. 320 vehicles more than the effective capacity.

H. Land Use-Based Analysis of Parking Demand
A second method to estimate parking demand in the study area is theoretical parking demand based on existing land
use development with engineering industry standard parking generation factors. Land use-based parking demand
analysis estimates how much parking a development will generate based on factors derived from averaged historical
observed parking data found in studies of similar land uses. A commonly used source of parking generation factors is
the Institute of Transportation Engineers (ITE) Parking Generation, 4th Edition. Although still the engineering standard for
estimating the parking demand of new development when no applicable local parking case studies exist, the
methodology has been called into question for reliance for too few or out of date samples used to calculate the factors,
and overly conservative results leading to overdesigned parking.24 The methodology also results in only a single answer
for a parking supply, usually enough parking to satisfy a chosen peak.

To improve upon the results of land use-based parking analysis, the Urban Land Institute (ULI) Shared Parking 2nd Ed.
Methodology can be used together with ITE factors to distribute parking demand by time of day based on the type of
land use. Shared parking factors are also based on averaged observed land use specific parking studies. The ULI Shared
Parking methodology allows for the estimation of how adjacent or nearby land uses may or may not be able to use the
same parking supply in a complimentary way based on a distributed parking demand curve for each land use.

The steps taken to create a land-used based estimate for the Portland study area were:

  Commercial building use data by floor were obtained from the City’s Tax Assessor office at the parcel
 level.
  Additional data on residential parcels were obtained from the City’s GIS department.
  Vacancy rates of 7 percent for office, 1 percent for residential, and 2 percent for retail/restaurant were
 applied after consultation with the City Planning Department.
  The hotel occupancy level in the study area was set at 70 percent based on the 2015 average annual
 hotel occupancy for Portland25
  Assumptions had to be made about the percentage of internal capture trips in the study area for each
 land use. Internal capture is the expected share of trips that are attracted to a land use while the
 customer’s vehicle is already parked for another purpose. An example occurs when an office worker
 goes to lunch on foot while their vehicle is parked at their office and the lunch trip does not extend the
 time the vehicle would already have been parked. Internal capture trips increase with dense mixed-use
 development, much like the study area. Low rates of internal capture of 10 percent or less were
 assumed except for restaurants in the study area which were assumed to have a 50 percent internal
 capture rate.
  ITE Parking Generation rates were used to calculate a peak parking demand for each identified land use
 at the 50th and 85th annual percentile demand levels according to ITE. The 50th percentile is intended to
 represent an average day, while the 85th is regarded to be the highest peak that should be designed for
 while remaining economical.
  The results of the ITE Parking Generation calculations were next processed through a spreadsheet of
 land use specific ULI Shared Parking time-of-day factors and then a spreadsheet of internal capture
 rates.
  The resulting charts give a combined peak parking demand by time of day that also shows how the
 parking demand of individual land uses crest and fall during the day while consuming and yielding
 shared parking.

Figure 54 is the shared parking curve for the ITE generated weekday 50th percentile demand of the study area. The
results of the 50th percentile calculation had a peak at 2pm of 14,470 vehicles, 480 vehicles more than effective study
area capacity at that time. Noticeably, the 50th percentile land-used based estimate is not far off from the peak adjusted
observed estimate in the prior section which found an average peak season high of 14,300 vehicle at 12pm. This is
indicative of the reputation of ITE Parking Generation factors as over predicting parking demand.

Another point made apparent from the land-use based parking demand calculations is that Downtown Portland appears
that it would have difficulty hosting a mid-day event at Cross Insurance Arena during the summer on a weekday. The
Arena parking demand was generated using the seating capacity as an input variable. Cross arena has a seating capacity
of 6,733 and is predicted by ULI Shared Parking Factors to have a peak parking demand of 2,200 vehicles. An event using
the full seating capacity of the Arena held mid-day during the peak season could push parking demand several hundred
over the total capacity of the study area according the land-use based calculations. Evening and weekend events at the
Arena, however, appear to be well accommodated for parking.

out very close to the observed occupancy with peak season adjustment which had a Saturday peak of 9,320 at 2pm.

 Figure 55: Saturday 50th Percentile Peak Demand Land-Use Calculated

When the weekday 85th percentile demand factors from ITE were applied to the study area land use, the results came
out unreasonably high with a peak of 17,270 at 2pm, approximately 1,500 more than the total parking capacity of the
study area. Such an occurrence would leave no open parking space in the study area and would also fill the public use
spaces in the quarter mile buffer area. It is unlikely that this is a good representation of the peak season in the Portland
study area and for this reason, the ITE 85th percentile demand factors are not applied further in this study. The 50th
percentile ITE demand factors together with the ULI Shared Parking methodology appear to better approximate what
was found to be a likely peak scenario based on the observed and adjusted results.

I. Existing Conditions Conclusion
In conclusion, Table 32 summarizes the following for the weekday existing conditions:

1) The results of the observed parking occupancy analysis performed in December, which was found to likely be a good
representation of recurring parking demand but lacked peak season visitor and increased ferry passenger parking
demand.

2) The observed parking occupancy analysis with calculated adjustments to account for additional peak summer season
parking demand related to higher ferry passenger ridership and higher levels of overnight and day visitors.

3)The theoretical land-use based parking demand estimated using ITE Parking Generation (4th Ed.) factors together with
ULI Shared Parking (2nd Ed) factors at the 50th percentile demand, which was found to be more realistic as an
approximation of peak season demand for the study area compared to the results using 85th percentile factors.

 Table 32:Weekday Existing Parking Demand Results Summary


While the observed parking occupancy in December was found to be 2,450 below effective capacity, after adjusting
average daily parking demand for the peak season, we find that the study area is likely approximately 290 vehicles over
effective parking capacity during the mid-day peak hour in the peak summer season. The land-use based calculation of
parking demand using 50th percentile factors estimated that the study area is 480 vehicles over effective parking
capacity. Travelers to the Study area do have access to an additional 1,300 off-street spaces with an effective capacity of
1,170 spaces within a quarter mile of the study area. However, this additional supply is shared with demand generated
outside of the study area which was not calculated during this study.

It was found that a high-range estimate of monthly parking supply within the study area, 10,750, is below estimated
employee monthly parking demand, 11,070. Additional monthly parking supply outside of the study area, such as
parking structures north of Cumberland Ave, have some additional monthly parking shared with land-use outside of the
study area and this additional supply appears to be needed to accommodate monthly employee parking demand in the
study area. Given the tight market for monthly parking, it is likely that unrestricted parking on streets surrounding the
study area are being used by employees of the study area.

It was found that during the peak summer season on a weekday, added parking demand related to higher ferry
passenger ridership levels alone is of an order magnitude capable of consuming much of the peak period off-street

vacant parking observed during December in zones surrounding the Casco Bay Ferry Terminal. When day and overnight
visitor parking demand is added to the weekday summer peak, a majority of whom visit the Old Port and Waterfront,
the pattern of how the vacant space observed during December fills up would appear to emanate from the Ferry
Terminal and Waterfront consuming vacant space gradually outward to Cumberland Ave.

On Saturday, it was found that off-street parking facilities were well below effective capacity. Table 33 summarizes the
Saturday existing conditions case:

 Table 33: Saturday Existing Parking Demand Results Summary


On-street parking during the weekday sample was found to be below 85 percent occupied overall in the study area
except for during the evening at around 7pm. Individual streets varied however, and it was found that Commercial St
was over capacity after 4pm, Exchange St was over capacity between 11am and 6pm, Middle St was over capacity
between 11am and 3pm and then again at 7pm, and Casco St was over capacity after 6pm.

Saturday on-street parking was above 85 percent occupied overall in the study area for much of the day after 1pm which
is likely giving the perception that there is little parking to be found when in fact, off-street parking is abundant on
Saturday, though at a higher price. Commercial St was over capacity from 1pm on. Both Middle St and Exchange St were
over capacity during all sampled hours except for 3pm. Spring St was over capacity after 6pm. Casco St was over capacity
from 11am onward.

J. Projected Future Parking Supply and Demand
This chapter of the report projects future parking supply and demand considering ferry passenger growth, tourism
trends to the Casco Bay Region, and three land use development scenarios that include new parking supply. Our
methodology is outlined here:

1). First, using recent historic ferry passenger and ferry vehicle transport data, we determine a daily parking demand for
ferry passengers 10 years into the future during the peak season.

2). Considering data from the Maine Office of Tourism, we determine if an additional growth factor for visitor parking
demand is needed in addition to the projected parking demand from ferry passenger growth and new land use
development.

3). Next a land use development analysis is carried out in the following steps:

a. A set of approved and likely development projects in the next 10 years were obtained from the City of Portland. Three
build-out levels, 50%, 75%, and 100% build out, are calculated to create three development scenarios. The scenarios are
compared with population growth estimates from Portland’s Comprehensive Plan and state employment growth
estimates.

b. The three development scenarios are then apportioned to the study area using the subarea zone geography
convention from the existing conditions chapter.

c. A combination of ITE Parking Generation (4th Ed) and ULI Shared Parking (2nd Ed) methods are used to calculate a time
distributed daily parking demand for each scenario based on land use development.

d. An accounting of the new development generated parking demand, newly built parking, and eliminated parking due
to construction reveals whether the development scenarios are projected to be parking demand neutral, create a net
new parking supply surplus, or create a future parking supply deficit.

J.1 Projected Ferry Passenger Parking Demand
Casco Bay Lines Ferry passenger ridership between the City of Portland Waterfront and the Casco Bay Islands has grown
in recent years by 12.5% between 2012 and 2016. A 10-year growth projection of ferry passenger parking demand is
calculated here continuing the recent 5-year growth trend. Table 34 shows the compound annual growth rates (CAGRs)
for annual passenger and vehicle volumes between 2012 and 2016.

 Table 34: Casco Bay Lines Passenger Growth 2012-2016

 Round-Trip Passengers 2012 2013 2014 2015 2016 Total % Growth Compounded Annual

* In 2012 the car ferry was dry docked and service was subcontracted

The passenger and vehicle growth rates were then used to project peak daily passenger and vehicle totals in 2027 as
shown in Table 35. To convert ferry passenger and transported vehicle volumes to projected parking demand, the same
set of assumptions that were made as in Section G.2 of the existing conditions chapter were applied. Those assumptions
were:

  Employment data shows that approximately 18% of the island resident workers who commute to the mainland
 work in the Downtown/Old Port. It is assumed that these commuters by and large do not drive between the
 ferry terminal and their work destination.
  For the remaining island resident workers, a drive mode share equivalent to the City of Portland’s for work trips
 is assumed for travel between the ferry terminal and their work destination. The City’s rate in 2015 was 73%
 drive alone, and about 9% carpool consisting of parties between 2 to 4 people.26
  The City of Portland’s drive alone and carpool to work mode shares are also assumed for the workers who
 commute from the mainland to the islands,
  For all other passengers including visitor trips, year-round island resident non-work trips, and seasonal island
 resident trips, it is assumed that average travel party size is 2.5, which was the average travel party size for day
 visitor parties to the Portland region in 201527. A drive mode share of 82% is assumed based on the total
 automobile mode share of work travel in the City of Portland in 2015 in lieu of more specific data.


Included in the future projection is an assumed rate of growth of the number of work commuters traveling to and from
the islands. Commuter populations were increased by 8 percent in keeping with the Portland Comprehensive Plan goal
of 8 percent population growth in 10 years. The result was a projection of an additional peak season daily parking
demand of 230 vehicles for ferry passengers using Casco Bay Lines as shown in Table 35. The ferry parking projection will
be added to both weekends and weekdays.

Forecasts of passenger demand for international ferry service to Nova Scotia were unavailable. Based on average daily
passenger data from 2014-2016, an average daily walk-on passenger total of 25 will be held constant for the future
weekday and weekend projections. It is estimated that parking demand related to the walk-on passengers is 10 vehicles.

The results project a total ferry passenger parking demand of 240 additional vehicles in 2027. Ferry parking demand
peaks in the evening and during the early morning hours before 7am. During the day, parking demand dips slightly as
island residents make trips using their vehicles and visitors return to their vehicles. The time of day demand distribution
from the Casco Bay Parking Garage is used an approximation for the time of day distribution for ferry parking demand.


J.2 Tourism Considerations
The Maine Office of Tourism does not forecast visitor levels, although it does set future goals for increased visitation,
such as first-time visitation and business visitation. Recent data on 2016 from the office of tourism showed another
strong year for increased visitors in Maine. Between 2012 and 2016, visitation grew by from 28 million visitors to 35.8
million visitors, which was a 28% percent increase overall and a compound annual growth rate of 5%. However,
visitation to the Greater Portland Casco Bay Region is not necessarily growing at the same rate as the state Maine




Fort Hill Infrastructure Page 101 of 179
 Page 174
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

because a lower percentage of visitors reported making the Portland region their primary destination in 2016 as
compared to 201228 29 30.

Our future estimate of overnight visitor parking demand to the study area is based on the growth in hotel rooms in each
development scenario. An occupancy rate of 70%, the annual average from 2016, is applied into the future scenarios.

Similar to the existing conditions land use-based parking analysis, the future parking demand estimates are based on
land-use generated parking demand using ITE Parking Generation (4th Ed) factors at the 50th percentile demand level
together with ULI Shared Parking (2nd Ed). The 50th percentile demand level factors were found to be a better
representation of Portland’s existing conditions peak season than 85th percentile factors, which produced an
unreasonably high peak too dissimilar from observed occupancy and calculated seasonal adjustment factors.

Land-use based parking generation does not delineate between resident and visitor parking demand, total demand is
based on the quantity of land-use development. The peak demand from the parking generation factors is already an
approximation of the high demand season, meaning additional demand from tourism does not need to be added unless
it is believed that tourism is increasing beyond the rate suggested by new development. New retail, restaurant, and
hotel development specified in the future projects have been sized in anticipation of tourism. Additionally, we are
accounting for growth in ferry passenger ridership in the future demand estimates, based on passenger growth since
2012, which is a way of accounting for projected island tourism growth.


J.3 Land-Use Development Scenarios Parking Analysis
Information on a set of approved and potential future projects within a 10-year time frame was obtained from the City
of Portland’s Planning Department and the Economic Development Department. Figure 56 shows the approximate
location of future projects within or very near the study area. The study area is shown divided into seven subarea zones
as defined in the existing conditions chapter for the sake of discussion. The location of the projects suggests both a
concentration of new parking demand in Subarea Zones 3 and 5, and a second concentration of new parking demand in
Subarea Zone 7, the Eastern Waterfront, that will include new demand in the eastern edge of Subarea Zone 6 at the
Maine State Pier.

Two additional scenarios were created to view the results of what might happen if less development than anticipated
were to occur. As a simplified way of doing this, the likely to occur but not previously approved projects listed in Table
37 and Table 38 were reduced in total size to create a scenario described as all approved development plus 75 percent
of likely development, summarized in Table 40. Similarly, Table 41 summarizes the last scenario described as all
approved development plus 50 percent of likely development.

J.3.4 Population Analysis of Development Scenarios

Between 2000 and 2010, on the Peninsula, the majority of new growth occurred in the vicinity of the Parkside, East
Bayside, and India Street neighborhoods, while Downtown, the West End, and a portion of the East End, lost population.
As mentioned in section B.4 in the existing conditions chapter, the population lost Downtown between 2000 and 2015
was nearly all due to losses in the population living in group quarters while the population of residents in occupied
households grew a small amount, by 0.3 percent.

According to the City’s comprehensive plan (2017), the City has set a goal of growing from a current population of
66,681 residents (2016) to a population of 72,000 residents by the year 2027. The desired increase of 5,319 residents
represents 8 percent in total population growth and would reflect a compound annual growth rate (CAGR) between
2016 and 2027 of 0.6 percent per year.

The comprehensive plan also says of the City’s goal of reaching 72,000 residents that, “This figure falls between the
medium and high growth scenarios developed based on USM's county growth model.”31 The USM county growth model
estimated a range of 2030 growth scenarios, from a high growth scenario which estimated a population of 81,000 to a
low growth scenario which estimated a population of 69,000.

The three development scenarios identified in this study consist of new residential units totaling 1,255, 963, and 671
units respectively for the Full Build-Out, the Approved Plus 75 Percent of Likely Development, and the Approved Plus 50
Percent Development scenarios.

The average household size in the study area is 1.5 residents based on the 2015 American Community Survey 5-year
estimate. The population increases resulting from each development scenario relative to the City, the Peninsula, and the
study area are summarized in Table 42.


 Table 42: 10-Year Relative Population Growth of Development Scenarios

 Development Residential Est. Pop Growth Growth Relative Growth Relative Growth Relative
 Scenario Units from Development to Study Area to Peninsula to City (66,681
 (1.5 Persons/Unit) (2,589 residents (23,248 residents residents in
 in 2015) in 2015) 2015)
 Approved + 50% 671 1,010 39% 4% 1.5%
 Approved + 75% 963 1,440 56% 6% 2.2%
 Full Build-Out 1,255 1,880 73% 8% 2.8%

The 10-year Full Build-Out scenario would result in a population growth of 1,880, which is 2.8 percent of the City’s
current population. The comprehensive plan does not say where the City’s goal of 8 percent growth would occur within
the City, however should the Full Build-Out occur, the City would need an additional 5.2 percent in population growth
relative to the present population, or 3,439 additional residents, in neighborhoods outside of the study area to reach 8
percent total growth by 2027.

Interestingly, the population growth from the Full Build-Out relative to the Peninsula is 8%. This means that if the Full
Build-Out were to occur, no further population gain on the Peninsula would be necessary for the Peninsula to have
grown in population by the same rate as the City’s overall 10-year goal.

 Portland’s Plan (2017) pg. 100

Fort Hill Infrastructure Page 107 of 179
 Page 180
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

The Full Build-Out population growth relative to the study area, which has a current resident population of 2,589, would
be 73 percent over 10-years, about 9 times the rate of growth compared to the City’s overall target of 8 percent. This is
in keeping with trends nationally and with the City’s comprehensive plan policies related to supporting mixed use
growth of Downtown as the center of the City and region.

Between 2000 and 2015, the study area population in occupied households grew by 0.3% total. During the same period,
the City population grew by 3.5%, as was shown in Table 6 and Table 7 in the existing conditions chapter. Should the
study area experience a relative population growth of 73 percent in the next 10 years, as implied in the Full Build-Out,
while the City grows by 8 percent during the same period, it would be a significant change in the relationship between
growth in the study area vs. growth in the City overall in recent years. The same can be said of the Approved Plus 50
Percent Likely and Approved Plus 75 Percent Likely scenarios, though less dramatically so. The Approved Plus 50 Percent
scenario would grow the study area resident population by 39 percent in 10 years. The Approved Plus 75 Percent Likely
scenario would grow the study area by 56 percent in 10 years.


J.3.5 Employment Analysis of Development Scenarios

According to employment forecasts developed by the State of Maine, the City of Portland is expected to see a net
increase of 16,610 jobs over the 30-year period from 2010 to 2040, a 25% total increase and a compound annual growth
rate of 0.7%. In 2014, the latest estimate available, the City of Portland had 67,648 jobs32. Using the same rate of growth
rate predicted by the State of Maine, 10 years of growth would result in 73,211 jobs in Portland, an increase of 5,563
jobs which is 8.2% total employment growth.

The study area currently has 17,149 total jobs. Between 2002 and 2014 the study area employment grew by 9.1% while
during the same period employment in the City grew by 5.2%. The study area gained employment at 1.75 times the rate
of the City during the period.

The implied employment from the three development scenarios was calculated using general employee occupancy
factors for each land use. The total number of employees expected in each scenario is summarized in Table 43.

Table 44 compares the estimated employment from the development scenarios with existing employment totals in the
study area and City.

 Approved + 75% 2,553 15% 4% 46%
 Full Build-Out 3,342 19% 5% 60%

The Full Build-Out scenario would result in a 10-year employment growth of 19 percent in the study area relative to
current employment. While this is a higher rate of employment growth than the State of Maine predicted for the City in
a 10-year period (8.2 percent), recent history does suggest that the study area has in fact tended to gain employment at
a higher rate than the City.

However, if the study area were to gain 19 percent in employment during a 10-year period when the City gained 8.2
percent, the study area’s rate of employment growth would be 2.3 times that of the City. This means that the Full Build-
Out scenario would add employment to the study area at a higher rate relative to the City’s growth rate compared to
the period between 2002 and 2014, when the study area gained employment at 1.75 times the rate of the city.

The Approved Plus 75 Percent Potential scenario represents an employment growth rate in the study area of 15 percent,
which would be 1.83 times more than a City employment gain of 8.2 percent, which is more in keeping with the recent
past in terms of how study area employment grew relative to the City.

The Approved Plus 50 Percent Potential scenario represents an employment growth rate in the study area of 10 percent,
which would be a rate 1.22 times more than a City employment gain of 8.2 percent, a slower rate of employment
growth in the study area relative to the City when compared to the period between 2002 and 2014.

J.3.6 Projection of Future Parking Demand

For the existing condition, parking demand was calculated two ways: observed demand with peak season adjustments
from tourism and ferry passenger data, and land-used based parking generation. For the 10-year demand projections,
only the land-used based method is applied with an adjustment for ferry passenger growth. Attempting to adjust
observed parking demand to the future is not typically done.

The development scenarios were apportioned to the study area using the Subarea Zones 1 through 7 geography
convention from the existing conditions analysis. A combination of ITE Parking Generation (4th Ed) factors at the 50th
percentile demand level and ULI Shared Parking (2nd Ed) factors were then applied to calculate a time distributed daily
parking demand for each scenario. The 50th percentile ITE factors were found to be a more realistic approximation of the
peak season in Portland compared to ITE’s 85th percentile factors in the existing conditions analysis, therefore the 85th
percentile factors were not applied to the future scenarios.

City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

Subarea Zone 1 has a surplus of 170 new parking spaces in effective capacity. The development in Subarea Zone 1 is a
parking garage intended for an adjacent tenant, which would likely open up space in other existing parking supply in
Zone 1 that could absorb most but not all of the excess future peak weekday demand from adjacent Zones 2 and 3 (195
vehicles).

A common theme in all the future scenarios is that future parking demand from the projected growth in ferry
passengers causes a net parking deficit in Subarea Zone 6, the location of the Casco Bay Ferry Terminal. There does not
appear to be leftover room to accommodate the projected growth in ferry passenger parking demand within the net
new parking supply from development. The future developments in Subarea Zone 7 alone appear to be at a deficit of
parking supply during the weekday peak of 195 spaces despite approx. 1,500 net new spaces in that zone under the Full
Build-Out scenario.

The finally tally for the Full Build-Out has a deficit of 150 in total parking supply, but a deficit of 460 if we consider that a
10 percent reserve supply of the net new parking should be maintained to keep circulation for parking functional.

As was found in the existing conditions analysis, the peak hour of the peak season weekday is likely currently over
effective capacity by 290-480 vehicles. The projected deficit from the Full Build-Out scenario could not likely be
absorbed into existing parking supply under these conditions without further diminishing the study area’s reserve
parking capacity needed to maintain a functioning parking system.

There is however, a noteworthy caveat to the future demand results related to residential parking demand. In Figure 57,
the scale of future residential development is apparent. The ITE parking generation factors predict 1.2 vehicles per unit
for mid-rise urban housing. Based on the 1,255 new housing units in the Full Build-Out scenario, and carrying forward a
1 percent vacancy rate from the existing conditions, the projection for residential parking demand is just under 1,500
vehicles. The ULI time of day curves predict that at 2pm on a weekday, 70 percent of the total residential parking
demand will be either occupied by resident vehicles or reserved and therefore not shared by other parking users.
However, if the parking supply for the new residential development is managed in a way that maximizes the possibility
of parking space re-use when residents are away, particularly during the work day, this could help lower the peak
parking demand curve.

Furthermore, our projections retained the internal capture rate for office land use at 2 percent, based on the present,
where only 2 percent of the employees in the study are also residents according to the latest available employment data
(LEHD 2014). If future residential development in the study area were to attract a higher percentage of residents who
also work in the study area, and do not use their vehicle to commute to work, this would raise the internal capture rate
for office parking demand. An internally captured office trip does not need an additional office parking space because
the resident employee leaves their vehicle at home. In this way, a single parking space would serve either a residential
purpose or an office purpose depending on the time of day. It would help lower parking demand to promote or
incentivize the occupancy of new residential development with employees (of any kind) who also work in the study area.

The results of the Approved Plus 75 Percent Likely and Approved Plus 50 Percent Likely scenarios are shown in Table 46
and Table 47 respectively. The parking demand deficit in each scenario is lower than the Full Build-Out, though not
dramatically so since newly built parking was scaled down along with development in the scenarios. The spatial parking
deficit patterns remain the same, since all developments considered likely but not yet approved were scaled down
evenly. The projected ferry parking demand was not scaled down with the development in these scenarios. In summary,
the Approved Plus 75 Percent Likely scenario resulted in a total parking deficit of 180 spaces, but an effective parking
deficit of 410 spaces. The Approved Plus 50 Percent Likely scenario resulted in a total parking deficit of 195 spaces, but
an effective parking deficit of 365 spaces.

higher than the future effective capacity between the hours of 10am and 4pm. The projected peak occurs at 2pm when
the demand for parking totals approximately 17,800 spaces while the effective capacity is 16,700 spaces.

The 10-year projected weekday results show that parking demand would need to be reduced by 940 to remain under
the effective capacity of parking supply within the study area in the Existing + Full Build-Out scenario. The Existing +
Approved Plus 75 Percent Likely scenario results in a need to reduce parking demand by 900 vehicles to remain under
effective capacity. Finally, the Existing + Approved Plus 50 Percent Likely scenario results in a need to reduce parking
demand by 840 vehicles.



J.3.6.2 Future Saturday Results

Next, the projected 10-year Saturday parking demand is described. Figure 60 shows the hourly Full Build-Out scenario
net new supply and demand alone. Between 6pm and 9pm, the projected future parking demand is greater than the
effective capacity of the net new parking supply, which is approximately 2,900 spaces. Demand generated by the new
development is projected to rise to just over 3,000 at 8pm, 100 vehicles more than the net new effective capacity to be
built.

 Figure 60: 10-yr Full Build-Out Scenario Only: Saturday Projected Parking Demand vs. Net New Supply



Table 49 shows the 10-year projected parking demand for each subarea zone at 8pm peak hour on Saturday. The
development in Subarea Zone 2 is an evening entertainment venue and the generated demand is based on full
occupancy of the 1,000 seats. The net new parking in Subarea Zone 3 has a surplus of 395 spaces because of the lack of
office demand during the weekend evening peak. In Subarea Zone 5, the net new parking is within 20 spaces of
supplying enough parking for the evening generated parking demand in the zone. Ferry passenger parking demand is at
its peak in the evening and creates a projected deficit of 240 vehicles generated from the Ferry Terminal in Zone 6.
Subarea Zone 7 has a projected deficit of approximately 45 from hotel, retail, restaurant and residential generated
demand. While the Full Build-Out scenario creates more net new total parking spaces than demand generated on
Saturday at 8pm, there is a parking deficit of approximately 130 spaces relative to net new effective parking capacity.

The Saturday Approved Plus 75 Percent Likely scenario parking demand deficit is higher than the Full-Build Out because
the approved development in Subarea Zone 2 and ferry passenger parking demand are not scaled down while many of
the likely developments that include net new parking are scaled down. The Approved Plus 75 Percent Likely result is a
deficit of 300 spaces relative to net new effective capacity as shown in Table 50.

Although all three 10-year Saturday scenarios are projected to generate more parking demand than net effective supply,
the existing condition land-used based calculated results had more than enough surplus parking capacity to
accommodate the future Saturday demand. Figure 61 combines the Existing and Full Build-Out scenarios.

 Figure 62: Saturday Peak Season 8pm Parking Supply and Demand for Combined Existing and Future Scenarios


The 10-year combined existing and future parking projections for all scenarios find that, as was the case in the existing
condition, parking supply is higher than demand during the Saturday peak as summarized in Table 52. The future
scenarios do however result in a slight decrease in the amount of parking available until effectively full on a Saturday at
8pm. In the existing condition, the Saturday 8pm peak had 1,940 available spaces until effectively full, while the Existing
plus Full Build-Out scenario has 1,850 spaces available until effectively full. Should the existing trend of over capacity on-
street parking with simultaneous under capacity off-street parking continue, the added 10-year parking demand under
any of the future scenarios could further shape perceptions of Portland as being a difficult place to find parking.

J.4 Conclusion
In the future parking demand section, we have shown the magnitude of approved and likely 10-year development in the
Portland study area. The development was shown to exhibit clustering in Subarea Zones 3 and 5 as well as separately in
Subarea Zones 6 and 7. Significant increases in study area resident population and employment are anticipated. The rate
of population and employment growth would be significantly higher in the study area as compared to rates that have
been projected for the City of Portland overall. This is not necessarily incompatible; however, it would require that the
study area add employment and especially residents at a higher relative rate than the overall growth rate of the City
compared to how the study area and City grew during the past 15 years. This is in keeping with policies of Portland’s
plan.

A 10-year growth assumption for ferry passenger demand was made by continuing the trend of the previous 5-years.
Associated parking demand from ferry passenger growth was calculated to be an additional 240 vehicles during the peak
season. The past 5-years saw a healthy growth in ridership, and continuing this trend may result in a future projection
somewhat on the high or conservative side. Nevertheless, the future scenarios did not provide enough surplus net new
parking that could absorb growing parking demand from ferry passengers.

Although tourism in Maine has been increasing robustly during the last 5-years, the data was not as clear on visitation to
the Portland region which may be relatively flat as a lower share of day visitors to the state reported the region as their
primary destination even though the total number of state visitors increased. Tourism was accounted for in the future
demand analysis as part of the ferry passenger growth trend and it is also embedded in the future land use parking
demand generation from the addition of new land use development such as restaurant, retail, and hotels which has
been scaled in anticipation of tourism.

Three future development scenarios, a full build and two scenarios that allowed for the possibility of less development,
were analyzed using a combination of ITE Parking Generation factors and ULI shared parking factors. The key results are
summarized in Table 53, the final figures have been adjusted by the difference between the land-use generated existing
conditions results and the observed and adjusted existing conditions results. This calibration was made assuming the
observed and adjusted existing conditions results were more accurate than the land-use based results and carrying the
difference forward into the future.

  Recommended Planning Range Goal for 10- year Parking Demand
  Reduction 700-750 0

It should be recalled that an additional 1,307 spaces in structured and surface lot parking available to the public with an
effective capacity of 1,176 vehicles outside of the study area within a quarter-mile buffer. This additional parking supply
serves a combination of travelers destined for the study area and travelers destined for land use outside of the study
area. The existing parking demand for land use outside of the study area was not observed. It should not be assumed
that this additional capacity can offset the projected parking demand deficit in the study area alone. Analysis in the
existing conditions chapter showed that the quarter-mile buffer area parking supply is likely already critical to meeting
the monthly parking demand of employees in the study area.

We therefore recommend that the City of Portland plan to reduce weekday parking demand in the study area by a range
of 700-750 vehicles in a 10-year horizon. We propose a goal of managing parking demand in the study area to be at or
just under the weekday peak hour effective capacity of parking supply inside of the study area, which is projected to be
in a range between approximately 15,480 to 16,870 parking spaces depending on the future build scenario.

In the following section, we offer a set of recommendations to address Portland’s critical need to manage overall
parking demand in the study area and the specific parking demands of key user groups experiencing difficulty parking.

K. Strategy Recommendations and Development

K.1 Introduction
In Task 1, the existing conditions report determined that overall parking demand in the study area, including on-street
and off-street parking, is likely 290-480 vehicles over effective parking capacity in the midday period on weekdays during
the peak summer season. Furthermore, it was found that during weekday evenings (after 5pm) and on weekends,
parking supply in the study area is well below effective capacity overall. However, on-street parking during the evening
on weekdays (5pm-8pm) and after 1pm on Saturday is at or over effective capacity along key commercial streets in the
study area.

The most urgent existing condition parking challenges are identified as:

  There is a scarcity of monthly parking offered for employees on weekdays during the work day.
  There are limited low-cost parking options for low wage earners in the study area.
  There are limited low-cost multi-day and monthly options for island residents who have a need to park a vehicle
 on the mainland accessible from the ferry terminal.
  Visitors during the summer season compete with employees of the study area for day parking, contributing to
 off-street parking scarcity mid-day on weekdays.
  High rates of on-street parking occupancy during weekday evenings and on weekends, in many sampled
 locations above 85%, is contributing to the perception that there is no parking, when in fact ample off-street
 parking is available during these periods, but at a higher cost.
  Unrestricted parking on streets outside of the study area, but within a walkable distance, are under pressure of
 increased use by travelers to the study area seeking day parking, including employees and day visitors. This is
 particularly relevant weekdays during the peak summer season when study area parking demand is at or over
 effective capacity.

In Task 2, the future demand report, three future development scenarios were identified, consisting of approved
projects and likely projects built out to 50%, 75%, and 100% of proposed development capacity.

The main parking challenges associated with the identified future parking scenarios are:

  In the Eastern Waterfront area, Subarea Zone 7, and the area surrounding the Casco Bay Lines Ferry Terminal,
 Subarea Zone 6, the projected demand associated with new mixed-use development combined with growth in
 ferry passenger parking demand will likely exceed net new parking supply on both peak (summer) weekdays in
 the afternoon and on weekends in the evening.

 While there is existing off-street parking capacity elsewhere in the Study Area on weekends to accommodate
 the growth in parking demand, there does not appear to be existing capacity on weekdays during the afternoon
 peak hour to accommodate the amount of parking demand that is projected to be over capacity from Subarea
 Zones 6 and 7.

  In Subarea Zone 3 located Downtown, the projected demand associated with new mixed-use development will
 slightly exceed the net new parking supply in that zone on peak season (summer) weekdays during the
 afternoon. Net new parking supply in adjacent Subarea Zone 1 will help to offset most of the projected parking
 deficit in Subarea Zone 3, but not entirely.



Fort Hill Infrastructure Page 123 of 179
 Page 196
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

The following recommended strategies are made to address overall parking demand and the specific parking demands
of key user groups including all employees, low-wage employees specifically, and island residents.

K.2 Recommended Strategies

K.2.1 Explore the Formation of a Non-Profit Transportation Association

A new non-profit organization, a Transportation Management Association (TMA) being just one example, could serve as
an important entity for bringing private and public-sector interests together to address collective parking challenges and
other mobility issues affecting the study area. We recommend the role of the organization to be a facilitator of solution-
finding for members and to play an important informational role to businesses in Portland.

Commonly, transportation associations form to pool private funding for shuttle services created to solve employer
mobility challenges. We do not necessarily recommend that the association itself contract with a fixed route shuttle
service provider. Instead we recommend that the association become well-versed in existing and emerging
transportation network company (TNC) services that use customized mobility solutions for individual members or
partnered members.

The advantages of TNC solutions over traditional fixed-route private shuttles are the possibility for on-demand and
custom routing, custom smartphone apps can improve the user experience, and depending on the arrangement,
members can pay for only the rides they use.

Key issues that a new transportation association could play an important role in addressing are:

  The difficulty employers and their employees are having securing monthly parking; specifically, we recommend
 the crafting of customized TNC solutions for employee mobility that could include new park and ride lots at
 underutilized and lower cost locations outside of the study area.

  Helping to connect employers with transit mobility solutions for employees. This could range from practical
 matters such as helping to integrate the procurement of transit passes, to a larger-scale programmatic role of
 serving as a unified voice for members to dialog with regional public transit providers, Amtrak, the JetPort etc.

  Collecting metrics on mobility issues, such as parking demand, that may help members solve mobility problems
 through coordination and sharing of unused parking spaces or crafting of another policy.

  Acting as a clearinghouse for information and ideas regarding Travel Demand Management. The association
 could also provide a venue for voluntary compliance monitoring with TDM ordinances.

  Identifying parking management strategies or programs that could benefit the area collectively or strategies to
 achieve a specific initiative, for example a large-scale special event.

  Marketing mobility and parking solutions to visitors to help prevent the perception that Portland is a difficult
 place to visit because of hard to find and expensive parking.




Fort Hill Infrastructure Page 124 of 179
 Page 197
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

K.2.2 Partner with Transportation Network Companies to Address Specific Parking Challenges

We recommend that the City of Portland explore partnering with TNCs to create customized programs to address three
specific issues: 1) island resident parking supply; 2) the limited availability of low cost parking for low-wage earners; and
3) surges in peak season visitor parking demand.


  The City could partner with a TNC to create a customized program for island residents to improve
 mobility between the Casco Bay Ferry Terminal and a location where multi-day parking is lower cost,
 more available, and more reliable compared to the current situation of a crowded on-street resident
 parking zone. The City could explore ways to share the cost of this program with the island resident on a
 per-ride basis, a one-time annual fee, or another means. We strongly suggest keeping the existing on-
 street resident zones for island residents, and we suggest this new option as an alternative that could be
 very attractive given the right price point and convenience of use.

The Chebeague Transportation Company (CTC) currently operates a shuttle bus between a satellite parking lot on Route
1 in Cumberland and the CTC ferry terminal in Yarmouth. Our recommendation for the Casco Bay Ferry Terminal would
work similarly, but replaces a shuttle bus with on-demand TNC service utilizing a smartphone app.

  The City could partner with a TNC to create a customized program for low-wage earners who are having
 difficulty finding affordable parking options close to their employer. The City could manage membership
 to such a program by requiring applicants already meet the requirements of another existing income
 restricted program. The program would allow low-wage earners to use a coupon code or custom app to
 use TNC travel between their employer and another location such as a park and ride lot or a transit
 center during defined working hours. The City could share the cost of this program with the employee
 on a per-ride basis, a one-time annual fee, or another means.


  The City could partner with a TNC to coordinate a well-publicized option for peak season visitors to park
 remotely at an underutilized lot, perhaps a distant lot with good highway access, and use TNC services
 to ride to and from the study area, particularly those traveling to the Old Port, Waterfront, and Casco
 Bay Islands. The lot could offer day and multi-day pricing that together with the cost of the TNC ride
 could be comparable to what would be paid for off-street parking in the study area. We do not
 necessarily suggest the City play a role in cost sharing for visitor rides, but rather set the cost of parking
 in the remote lot intentionally to make the program viable.


K.2.3 Expand Specific Island Resident Parking Programs

Expand island resident parking programs to include a program where island residents may remit a resident parking
permit in exchange for ridesharing subsidy or stipend to use as they see fit. This is like the suggestion above, but could
be less programmatic and may not include a designated off-site lot. The City could also explore the possibility of
allowing island residents to park in another residential zone that has surplus on-street parking and use ridesharing or
transit to reach the Ferry terminal.

K.2.4 Pilot Test Higher Cost On-Street Parking in High Demand Areas

One of the main findings of the study was that on-street parking is at or over capacity during weekday evenings and
during most observed hours on Saturday. One side effect of over capacity on-street parking for businesses is lower
customer turnover. Residents, employers, and their visitors may experience more difficulty finding short term on-street


Fort Hill Infrastructure Page 125 of 179
 Page 198
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

parking, and a higher incidence of double parking for pickup and drop-off activities. Stakeholders will need to define
what an acceptable level of on-street parking occupancy is, we suggest 85 percent, and if it is acceptable to use meter
pricing as a mechanism of influencing turnover and on-street occupancy levels.

If higher turnover is defined as a goal, one way to increase parking turnover would be to pilot test higher on-street
parking rates and extended meter hours to 8pm in high demand areas such as Commercial St. A pilot test would mean a
short-term experiment with a known end that is followed by an assessment of the results. The goal of the pilot would
be to determine if Portland parking users respond to the price increase with higher turnover rates and whether
stakeholders decide the higher turnover rate was beneficial.

K.2.5 Extend On-Street Meter Hours to 8pm City Wide

The on-street occupancy data shows that occupancy levels rise above capacity on weekends beginning near 4pm when a
user would be able to pay for two-hours of on-street parking and leave a vehicle for the remainder of the evening. If
stakeholders decide that maintaining a two-hour turnover up until 6pm is beneficial, which it may be for some
stakeholders such as restaurants, the meters could be extended until 8pm so that cars cannot be left on the street for
the evening with a two-hour payment until 6pm. Additional outreach would be necessary before any such change could
be implemented.


K.2.6 Improve Parking Management and Technology

It is recommended that parking operators continue to utilize the latest technology in operating their parking supply
including sharing pricing, hours, and even real-time occupancy data with customers via smartphone apps. The more
customers know about where parking is available and at what price before departure or en route, the better the parking
experience and more efficient use of available space study area wide.

To address the issue of overcrowding of on-street parking during evenings and weekends while off-street parking is
underutilized, parking managers could consider offering more competitive pricing with on-street rates during the first
one or two hours of stay.

More operators might consider offering evenings only monthly passes that might attract evening shift workers who
would otherwise avoid higher priced hourly parking close to their employer.

Implement Transportation Systems Management (TSM) practices to better utilize existing parking supplies. One of the
challenges associated with parking in Portland is knowing where to park. There are several approaches to addressing this
problem. First, we recommend the review and implementation of any remaining initiatives identified in the 2013
Portland Peninsula Vehicular Wayfinding Plan specifically related to parking signage and wayfinding in the Old Port,
Waterfront, Arts District, and Eastern Waterfront. If recommendations in the plan are found to be out of date, we
recommend a new City led effort to study how parking wayfinding can be optimized through signage and technology.

Technology is the wayfinding of the future. Encourage maximum use of technological tools that guide the public to
available parking spaces at known prices. Smartphone apps can market and incentivize the use of existing parking by
allowing users to price compare, reserve, purchase, and way find with one tool. Such programs maximize the efficiency
of existing parking while reducing congestion and vehicle miles traveled.

City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

K.2.7 Change Parking Requirements and Regulations

Manage parking demand by reducing parking requirements for residential units in the urban core to less than 1 space
per unit, while slightly increasing parking requirements for office from one space per 400sqft to one per 300sqft. The
projected parking demand suggests that weekday mid-day parking will be over effective capacity. Increasing office
parking requirements slightly will relieve part of this demand gap. However, we do not recommend closing the new gap
entirely with new parking supply. Some of this parking supply gap should be closed through better management of
citywide parking supplies. We suggest targeting 50% of the parking supply gap to be closed through parking
requirements for land use approvals, while closing the balance through parking management strategies.

Any increased structured parking supply should be specifically designed to be repurposed as retail space, due to the
widely anticipated likelihood that structured parking demand will decrease substantially with the advent of the
autonomous vehicle. While some believe that wide adoption of autonomous vehicles is many years in the future, it is
important to note that structured parking costs are routinely amortized over 30 or more years. Based on current studies,
it is highly likely that autonomous vehicles will result in a substantial reduction in parking demand, thereby undermining
the financial models that allow for commercial parking garage developments. Many underwriters are already
questioning the validity of parking garage pro formas in dense urban environments.

K.2.8 Improve Parking Policies in the Context of Land Uses Permits

As part of the city’s upcoming land use code rewrite, consider requiring additional parking data and or trip or parking
generation studies as a component of all site plan review. Requesting that developments provide parking and trip
generation information on a periodic basis will help the city calibrate its parking policies to reflect actual demand and
allow for more informed policy decisions. This data collection effort should include pricing information (if applicable) for
spaces that are sold or rented to tenants.

In addition, strengthen the policy of allowing fees-in-lieu. If the current $5,000 minimum per space program has had low
participation, the problem could be uncertainty about how the City’s Sustainable Transportation Fund will benefit
development. Contributors to the fund must understand how the funds will be used. This is critical to lenders and
investors looking to underwrite land development projects so the payment is viewed having a benefit for the project.
The City should consider more marketing or public engagement related to the annual Sustainable Transportation Fund
Appropriations Schedule. The City could use a variety of platforms to state how the Sustainable Transportation Fund is
being used, follow through on the plan, and then let constituents know via social media or other means the results of
the investment.

K.2.9 Increase Car Sharing Use

Facilitate car sharing through parking strategies. The use of U-Car and other car share opportunities can have a
significant benefit for islanders and residents of the study area if made convenient enough. Car sharing can reduce
demand for a landside car, while facilitating travel on the Peninsula for routine trips. One or more shared cars should
frequently be accessible from the Casco Bay Lines Ferry Terminal, in the parking garage or via a short trip either by foot
or using a ridesharing app.

Additionally, new peer to peer car sharing apps, e.g. Getaround or a similar company, could allow residents of the study
area to rent their personal vehicles to islanders or vice versa. A resident who lives and works in the study area may have
a vehicle that is parked at home during the work day which an islander could rent. An islander who keeps a vehicle on
the mainland but does not use it daily could rent it to residents of the study area on a short-term basis. The apps
simplify the coordination and transactions necessary to rent. The companies provide special insurance, and allow the car
owner to choose renters with favorable feedback ratings.

 Waterfront

K.2.10 Continue Implementation of TDM Recommendations from the 2008 Peninsula Transit Study

Continue to pursue the adoption of multiple strategies for single occupancy vehicle parking demand reduction through
travel demand management (TDM) in the study area as recommended in the 2008 Portland Peninsula Transit Study. The
study outlined TDM strategies, some of which have been implemented, e.g, fee-in-lieu payments as part city’s zoning
code and the creation of the Sustainable Transportation Fund. However, unimplemented strategies remain. TDM
strategies that could address the Study Area’s parking challenges include:

  Requiring new development in the study area become a member of the new transportation association and
 require the implementation of TDM ordinances such as:
 o Appointing a mobility coordinator for the development to interact with the transportation association.
 o Provide a car share space on-site.
 o Offer employees the option to purchase a pre-tax monthly transit pass.
 o Create incentives and educate employers on parking cash-out programs where employees may forgo an
 employee provided parking spot for a one-time payment.
 o The unbundling of parking and residential units so a resident is not obligated to take a parking space if
 they do not want one or own a car.

The Peninsula Transit Study also made a number of detailed transit service recommendations that have yet to be
achieved. We recommend continued pursuance of the following goals:

  Increase the peak period frequency of key Peninsula routes to 10-20 min headways
  Provide a direct link between the Portland Transportation Center and Downtown/ Waterfront. As development
 on the Eastern Waterfront progresses, service should extend there as well.
  Use signal prioritization and other techniques (e.g. queue jump lane) to help move buses through congested
 areas.

K.2.11 Additional Transit Recommendations

Additionally, we recommend the consideration of a downtown circulator route specifically meant to transport riders
between the Waterfront and Cumberland Ave in a loop. There is a need to make available parking uphill from the
Waterfront more attractive to better distribute parking demand within the study area.

The introduction of GPS enabled bus arrival tracking in Portland during 2016 is an important advancement. The City
should encourage the creation of additional smartphone apps that utilize the open-source bus location data. The City
could organize a hack-a-thon, a contest, or another incentive to spur user engagement with the new information
technology.



K.2.12 Bicycle Infrastructure

It is encouraging that the final design for the Franklin Ave reconstruction will include new bike lanes to both cross
Franklin Ave and travel along it. The eventual realization of that project should help raise the bicycle commute share to
the study area. If the City can raise the bicycle commute share during the peak summer season especially, it could play a
role in managing peak parking demand.

Additional investment in bikeways, bike lanes, bike paths, and byways to improve bicycle access from off-peninsula is
needed to raise the bicycle mode share of travel to the study area.



Fort Hill Infrastructure Page 128 of 179
 Page 201
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

The City will have the opportunity to observe the new bike sharing initiative to be launched in Portland in 2018. We
recommend the City support additional bike share infrastructure should the pilot program prove successful. Bike sharing
could be part of a mobility strategy between outlying parking areas or transit hubs and high-demand destinations.


K.2.13 Convert Unrestricted Parking

If further study shows unrestricted on-street parking within walking distance to the study area is over capacity and is
being used for longer duration parking than desired by stakeholders. Conversion of unrestricted spaces to time limited
zones or metered spaces is recommended. It is recommended that this be carried out gradually so that the effects of
parking demand on the study area can be monitored for adverse impacts should significant new parking demand be
forced into the study area. The unrestricted spaces on Commercial St west of the study area could potentially be
converted to metered spaces if a successful low-wage earner remote parking program were implemented as described
in Section K.2.2, since those spaces are intended to provide at least some no-cost parking near the study area.


K.2.14 Marketing and Advertising

The City could continue to support a marketing and advertising campaign to raise awareness and improve perception
about multi-modal access to the study area; including parking strategies, smartphone apps, and parking prices.
Campaigns should also highlight transit and bicycle commuting opportunities.


K.2.15 Additional Data Collection

We recommend periodic data collection on parking demand, particularly during the peak season since this effort
collected data during the winter season. Also recommended is data collection that would measure public knowledge
about multi-model access to the study area and willingness to pay for transportation and parking services. Establishing
baseline data on these topics will greatly help to develop performance measures for any solutions the City pursues.
Having high quality measures of effectiveness can be key to attracting state and federal funding.


K.2.16 Construct Additional Structured Public Use Parking Supply

If stakeholders decide that additional parking capacity is a necessary component to the City’s overall parking demand
management strategy. The construction of up to approximately 500 to 750 new structured parking spaces for public use
by travelers to the study area could be explored. We recommend the consideration of repurposeable parking structure
design to allow for the possibility of a change in use over the design life of the structure.

L. Implementation and Funding
This section identifies potential local, state, and federal funding sources applicable to the recommendations in Chapter
K. First, a short description of potential funding sources, then Table 54 summarizes each recommendation from Chapter
K with applicable funding sources.


L.1 Local Funding Suggestions
A Development Impact Fee


The proposed fee is a transportation impact fee scaled to the size, intensity, and or land use type of new development in
the study area for funding travel demand management, workforce mobility, or parking demand management related
initiatives. This fee would be separate from the existing optional parking in-lieu of fee in the City’s Land Use Code.

A Special Purpose On-Street Parking Meter Rate Increase


The proposed meter rate increase is for high-demand locations, such as Commercial St, Exchange St, and Middle St. It is
suggested that the collected revenue be used specifically for mobility initiatives for low-wage earners and island resident
commuters having trouble parking in the high-demand areas. It is also proposed that the purpose of the meter rate
increase be clearly communicated to the public and the programs funded by the new revenue be clearly explained.


L.2 State Funding
The State of Maine collects revenue from gasoline tax and other transportation related user fees into a State Highway
Fund. State Highway Fund expenditures are primarily allocated to road and bridge improvements, supporting traffic law
enforcement, safety, and ferry passenger service operations. Funding for transit and other mobility programs is
comparatively small and has not grown significantly in recent years. It doesn’t seem probable that tax and user fee
revenue collected by the State will be a major source of funding for new mobility initiatives in the study area
surrounding Downtown Portland. However, a mobility initiative with regional appeal or one that can be replicated
elsewhere in the State should at least request a State contribution toward a local match requirement needed to
leverage federal funding assistance.


L.3 Federal Funding
There are a several federal funding programs administered by the Federal Highway Administration (FHWA) and the
Federal Transit Administration (FTA) that are applicable to the mobility recommendations in Chapter K. What follows is
a brief description of relevant federal transportation grant programs, made law under the most recent federal
transportation bill, the Fixing America’s Surface Transportation (FAST) Act of 2015, which authorized federal
transportation funding through federal fiscal year 2020.


L.3.1 Formula Grant Programs

A number of federal transportation grant programs are administered jointly by the FHWA and FTA as formula programs.
This means that a formula defined during the writing of the transportation bill reauthorization is used to allocate federal


Fort Hill Infrastructure Page 130 of 179
 Page 203
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

funds to states on an annual basis considering factors such as population, federal fuel taxes paid, transit revenue miles,
etc. Each grant program may use a different formula. After funding is allocated to the states, a second formula then
applies for allocating funds within each state between state departments of transportation (DOTs) and regional
metropolitan planning organizations (MPOs). The City of Portland and other eligible agencies may then apply for federal
grants through either a regional MPO or the DOT in a competitive annual process. Eligible projects in most cases should
be included in a regional long-range plan (LRP), state implementation plan (STIP), and a regional transportation
improvement plan (TIP) where applicable. With some exceptions, the federal grant programs typically offer funding
assistance of up to 80 percent of project cost requiring a 20 percent local match at minimum. Four examples of formula
grant programs are described below.

L.3.1.1 Surface Transportation Block Grant Program

The Surface Transportation Block Grant Program (STBG) is the most flexible of the federal transportation grant programs
covering a wide variety of eligible projects related to surface transportation including capital investments, planning,
design, asset management, research, and training to name a few.

L.3.1.2 Transportation Alternatives Program

The Transportation Alternatives (TA) program is a subset of the STBG program meant for projects pertaining to
alternatives to vehicular transportation such as bicycle and pedestrian facilities on and off road including recreational
trail projects.

L.3.1.3 Congestion Mitigation Air Quality Program

The Congestion Mitigation Air Quality Program (CMAQ) is a grant program meant to provide assistance in funding
transportation projects that help meet or maintain compliance with the Clean Air Act. Although Maine is currently in
attainment of federal air quality standards, the State still receives a minimum apportionment of CMAQ funding for
projects that improve or maintain air quality. CMAQ funds are provided on a reimbursement basis, meaning funds are
not provided until work is completed.

L.3.1.4 Urbanized Area Formula Funding Program, Section 5307

The FTA administers an Urbanized Area Formula Funding Program, also known as Section 5307. Eligible activities include
a variety of transit planning, engineering, design, capital investment, and related communications technology. Some
activities related to mobility management programs are also eligible under the program. Urbanized areas with a
population over 200,000 are usually not allowed to use Section 5307 grant funding for transit operating expenses,
however, a Special Rule exists allowing some urban areas to do so. The Portland, ME urbanized area is currently allowed
to use a limited amount of Section 5307 funds for transit operating expenses.


L.3.2 Competitive Grant Programs

There are also grant programs administered by FHWA and FTA that are allocated through competitive processes at the
federal level. Eligible applicants apply directly for the grants through one of the federal agencies and awarded funds do
not count against the formula grant funds received by the states. The grant programs typically offer funding assistance
at a maximum of 80 percent of project cost, though applicants are encouraged to apply for less to better the odds of
receiving funding. Two examples of competitive grant programs are described below.




Fort Hill Infrastructure Page 131 of 179
 Page 204
City of Portland, ME Parking Study for Downtown, The Old Port, and The Eastern
 Waterfront

L.3.2.1 Passenger Ferry Grant Program

The Passenger Ferry Grant Program is a competitive grant program administered by FTA for projects related to
passenger ferry systems in urbanized areas. In addition to directly supporting capital expenses related to ferry boat
service, eligible projects include enhancements to terminals and connectivity to other modes of transportation.


L.3.2.2 Mobility on Demand Sandbox Demonstration Program

The Mobility on Demand (MOD) Sandbox Demonstration Program was the first program of its kind created by the FTA in
2016. The MOD program is part of a broader long-range policy visioning effort at the USDOT called Beyond Traffic.
Although the MOD program has already fully allocated its budget of $8 million in awards, future programs funding MOD
demonstrations will likely follow in years to come. The MOD program funded innovative pilot projects in communities
seeking to integrate mobility on demand services such as bike sharing, car sharing, and demand-responsive buses and
vans with traditional transit services. The integration of smart phone technology across MOD services and transit was
also a key component of many awarded programs. Eleven grants were awarded including one to The Vermont Agency of
Transportation which received $480,00 to create a statewide transit trip planner that will attempt to enable various non-
fixed route mobility services to be integrated with fixed route transit services using smartphone technology.



L.4 Conclusion
This chapter offered ideas for funding sources to support the recommendations made in Chapter K to reduce parking
demand in Downtown Portland, The Waterfront, and The Eastern Waterfront over the next ten years. In Table 54, each
recommendation from Chapter K is listed with the relevant funding sources described here in Chapter L.

Capacity count methodology: For surface lots and structed parking included in the City’s seasonal parking inventory, the
published total of spaces were used. All remaining surface lots not included in the City inventory were manually counted
using Google Earth aerial photography. For structed parking not included in the City inventory (which were typically
private use garages), estimates were made using a combination of Google Earth aerial photography and Google Street
View to determine the number of parking levels. The number of residential units associated with a private residential
garage also informed private garage estimates.

N. Appendix B: On-Street Parking Observed Data Maps and Charts

 The On-Street Parking Observed Sample Coverage Locations




On-street parking supply for the street block faces designated above were counted manually in the field. Five observers
were assigned individual data collection routes. Parking occupancy was collected by recording the last three digits of
parked vehicle license plates hourly between 8am and 8pm on a Thrusday, December 1, 2017 and between 10am and
8pm on a Satruday, December 3, 2016.

Total on-street parking capacity for the remainder of the study area was counted manually using Google Street View
with edits from the City on the recently developed Eastern Waterfront.
