17.14.020 Regulating plan – Land use districts and site orientation standards.
17.14.030 Site planning and design elements.
1. Provide clear objectives for those embarking on the planning and design of projects in downtown Chelan.
2. To preserve and enhance downtown’s historic resources and character.
3. To ensure that new mixed-use and commercial development is of high quality and appropriate to downtown’s character.
4. To retain the generally small scale residential quality of residential areas.
5. To upgrade the visual appearance of downtown’s principal vehicular corridors.
6. To promote increased pedestrian, bicycling, and transit use downtown.
7. To increase awareness of design considerations among the citizens of Chelan.
8. To maintain and enhance property values within Chelan.
B. Applicability and Compliance. The downtown code provisions herein are intended to supplement other provisions of this title and other existing city codes applicable to developments. Where there is a conflict between the provisions of this chapter and other codes, the provisions herein shall apply as determined by the director.
Unless otherwise noted, code provisions in this chapter apply to all construction within the downtown planning area (see Figure 1). This includes master plans, planned unit developments, subdivisions, and new construction. Different sections within this chapter often apply only to specific types of development (such as commercial or multi-family development) and are thus clearly noted. New construction must comply with the code provisions in this chapter.
1. Level I remodels/additions include all exterior remodels and additions commenced within a three-year period that affect the exterior appearance of the building and/or increase the building’s footprint by up to fifty percent. The requirement for such remodels/additions is only that the proposed addition and improvements meet the standards and do not lead to further nonconformance with the standards. For example, if a property owner decides to replace a building facade’s siding, then the siding shall meet the applicable exterior building material standards, but elements such as building articulation would not be required.
a. The location and design of the addition/remodel shall be consistent with landscape street frontages per Section 17.14.020(D): Provide a landscaped setback, locate parking to side or rear of building addition, provide weather protection over the building entry, and meet minimum facade transparency requirement.
b. Provide clear access to the sidewalk from the building entry and meet other applicable pedestrian access provisions per Section 17.14.030(D).
c. Comply with applicable service area and mechanical equipment, lighting, and parking lot design standards per Sections 17.14.030(F) through (H).
d. Comply with applicable architectural character standards in Section 17.14.040(B).
e. The building addition shall comply with architectural scale provisions of Section 17.14.040(C).
f. The entire building shall comply with building elements/details, materials, and blank wall treatment standards of Sections 17.14.040(D) through (F).
3. Level III additions include all building additions commenced within a three-year period that increase the building’s footprint by more than one hundred percent. Such additions shall conform to all standards.
Figure 1. Downtown planning area.
2. Standards use words such as “shall,” “must,” and “is/are required” signifying required actions.
3. Guidelines use words such as “should” or “is/are recommended” signifying voluntary measures.
4. Departures are provided for some standards. They allow alternative designs subject to administrative approval by the director provided they meet the intent of the standards and guidelines. The director shall document reasons for approving all departures (to be maintained with project application records) for the purpose of providing consistency in decision-making by the city.
Furthermore, the document contains some specific standards that are easily quantifiable, while others provide a level of discretion in how they are complied with. In the latter case, the applicant must demonstrate to the director, in writing, how the project meets the intent of the standard.
1. Development review processes shall be as set forth in Title 19, except that any building permit applicants seeking departures to the provisions in this chapter shall be reviewed as a Type IIA permit approved by the director. The director may request assistance by the planning commission, Historic Downtown Chelan Association (or other similar organization), or design professionals in determining whether projects comply with the standards herein.
2. Verification of Historic Downtown Chelan Association Review.
a. To provide the Historic Downtown Association (HDCA) the opportunity to provide input to the administrator for projects located on storefront streets as identified on the regulating map at Section 17.14.020(B), the developer shall submit the proposed project to the HDCA design committee to verify conformance with this chapter.
b. As a condition to the administrator accepting a project permit application for projects described in subsection (D)(2)(a) of this section, the application shall include (i) HDCA’s verification of its review, (ii) proof that thirty days elapsed after submitting the project to HDCA and that no verification was provided, or (iii) proof the design committee is inactive.
c. Verification of the project permit application by HDCA shall not be determinative of the project’s compliance with this chapter, but is limited to ensuring HDCA has had an opportunity to review a project permit application to provide input to the director regarding a proposed project.
d. For purposes of this chapter, a building permit application shall include applications for exterior remodels, departures, additions and new building(s).
E. How to Use This Downtown Code.
1. First, review Section 17.14.020, Regulating plan – Land use districts and site orientation standards, and map (Figure 2) to determine which land use district your property is within and what type of street your property fronts onto. Then review the standards that apply to the applicable land use district and street type designation within this section. The land use district standards (Sections 17.14.020(C)(2) and (3)) identify permitted uses, maximum building heights, setback requirements, and minimum open space requirements. Site orientation standards (Section 17.14.020(D)) identify what types of building frontages are allowed and where off-street parking is allowed.
2. Next steps depend on what type of development is proposed.
b. Single-family, duplexes and triplexes, accessory dwelling units, cottage housing, and townhouses shall comply with the applicable subsection of Section 17.14.050.
Townhouses are considered a type of multi-family use, and thus are subject to Sections 17.14.030 and 17.14.040 unless otherwise noted and applicable provisions of Section 17.14.050. (Ord. 1410 § 3 (Exh. B) (part), 2010).
A. Purpose. This section establishes land use districts and street type designations together with standards for each district and street type to guide the development of downtown Chelan properties consistent with the vision of the downtown master plan.
1. The regulating map (Figure 2) designates the locations for five downtown land use districts, indicates applicable height limits, and designates the locations of four different street types.
2. DMR Properties Not Included in Regulating Map. The DMR designated lands on the official zoning map and not included on the regulating map shall be regulated consistent with the DMR District regulations in this chapter.
C. Overlay District Uses and Dimensional Standards.
1. Land Use Districts Defined.
a. Downtown Mixed-Use (DMU). The purpose of the DMU District is to provide for a pedestrian-oriented mix of commercial, mixed-uses, and residential uses.
b. Tourist Mixed-Use (TMU). The purpose of the TMU District is to provide for residential uses and tourist-oriented uses in a pedestrian-friendly setting.
c. Downtown Mixed Residential (DMR). The purpose of the DMR District is to provide for a mix of residential uses that build on the established historical development patterns within the downtown area.
d. Downtown Single-Family (DSF). The purpose of the DSF District is to maintain the established single-family character of these areas.
e. Public. The purpose of the public district is to provide for public uses within the downtown planning area.

d. To reduce the horizontal glare and vertical light trespass from a development onto adjacent parcels and natural features.
e. To discourage the use of lighting for advertising purposes.
f. All outdoor lighting on public and private property shall comply with the dark sky provisions of Chapter 17.62. Exceptions may be allowed by the director for pedestrian-oriented lighting associated with commercial uses and/or mixed-use buildings.
1. Intent. To minimize potential negative impacts of parking lots on downtown’s visual character, pedestrian environment, local water quality conditions, and adjacent uses.
2. Surface Parking Lot Screening Standards.
Figure 26. Parking lot planting buffer with low wall.
Figure 27. Elevated parking lot planting buffer.
iii. Provide at least ten feet of Type C landscaping.
Figure 28. Ten-foot parking lot buffer with Type C landscaping.
All options above should choose and maintain plantings to maintain eye level visibility between the street/sidewalk and parking area for safety. This means that shrubs and other low plantings should be maintained below three feet in height while trees (once they achieve taller heights) should generally be trimmed to up to the eight-foot level. See Figure 29.
Figure 29. Parking lot planting buffers shall emphasize the 3:8 rule for visibility and safety.
b. Where new surface parking lots or parking lots associated with Level III additions are located along side property lines, a six-foot screen fence shall be required on the property line with at least five feet of Type A, B, or C landscaping in front of the fence. Breaks in the fence/landscaping are permitted for internal pedestrian and vehicular connections between properties. Properties fronting on designated storefront streets and/or those with shared parking agreements with applicable neighbors are exempt from this requirement. Departures will be considered by the director provided they meet the intent of the standards (see Section 17.14.020(B)(2) for considerations).
3. Other Relevant Code Sections.
a. Section 9 (Parking Standards) of the City of Chelan Development Standards Manual.
b. Parking lot pathway standards set forth in Section 17.14.020(D)(4).

2. Applicability. Unless otherwise noted, the provisions in this section apply to all nonresidential and multi-family development types within the downtown planning area.
1. Intent. To promote architectural design that reinforces and strengthens downtown Chelan’s unique small town/historic character/distinct setting. The focus is to encourage architecture with a strong sense of human scale, fine detailing, quality materials, sensitive to the environment, oriented to pedestrians, and designed appropriate to the site’s unique context. This approach is intended to allow for a diversity of architectural styles provided they meet the design standards of this chapter.
2. Architectural Character Standards and Guidelines.
a. Historic Core (Woodin Avenue between the River and Sanders Street).
i. Historic Buildings. Property owners of buildings constructed prior to 1950 are strongly encouraged to use the Secretary of the Interior’s Standards for the Treatment of Historic Properties (web: http://www.nps.gov/hps/tps/standguide/) (hard copy also available at City Hall) as a guide to preserve, rehabilitate, restore, reconstruct, or add to historic properties. These standards provide detailed recommendations on restoration, maintenance, repair, replacement, design, alterations, building materials, roofs, interiors, etc. Also, the state of Washington’s website provides contacts and technical assistance related to historic preservation at: http://cted.wa.gov/site/411/default.aspx. Applicants are also encouraged to consult with the Historic Downtown Chelan Association and/or other local resources for design guidance involving planned remodels/additions to pre-1950s buildings.
Historic photographs are extremely useful in determining historic precedent. Contact the city or Chelan Historical Society regarding historical photographs of downtown Chelan.
(A) Covering over original windows or design details on identified historic buildings is prohibited.
(B) Alterations to historic materials should be minimized.
(C) Original architectural features should be repaired rather than replaced. If replacement is necessary, replacements should match the original in design, construction, color, and texture as close as possible.
(D) Missing architectural features should be replaced with an accurate duplication of the original features. However, a second acceptable option for the replacement feature is a new design that is compatible with the remaining character-defining features of the historic building. The new design should always take into account the size, scale, and material of the historic building itself and, most importantly, should be clearly differentiated so that a false historical appearance is not created. See Figures 32 and 33 for example facade enhancements/renovations.
(E) Unique features and examples of skilled craftsmanship should be maintained and protected.
(F) For facade additions to historic buildings, such additions should either extend the facade through use of consistent articulation, materials, and roofline treatment or design the addition to look like a separate building and comply with the guidelines for new buildings referenced in subsection (B)(2)(a)(iii) of this section.
The director may allow alterations to the side or rear facades that are not character defining; provided, that the alterations do not interfere with existing building features or alter the historic character of the building. The director may allow alterations to the original primary facades in order to accommodate a desired use, provided deviation from historic conditions is minimized.
Figure 31. Illustrating how simple facade enhancements can upgrade the historic character of downtown.
Figure 32. Illustrating a desirable facade renovation to an existing Woodin Avenue building. Use of original facade materials is encouraged, if possible. Otherwise, use durable materials compatible with the facade and historic character of downtown.
ii. Nonperiod Architecture. Existing architecture which is not consistent with the early 1900 style and represents later periods is also encouraged to celebrate distinctive design features, except where such features conflict with other standards and guidelines herein, as determined by the director. Renovations of these structures should facilitate pedestrian access. Unique signage and design elements which are not inconsistent with the remainder of the guidelines are to be encouraged.
iii. New Buildings. Applicants for new buildings shall successfully demonstrate how they have based the building facade’s design on the form and elements common to early twentieth century downtown structures. This can be done through comparable facade massing and articulation, careful handling of the storefront and building top, and compatibility of materials and colors. Figure 34 below identifies desirable characteristics of existing buildings. Applicants may consider modern interpretations of these building elements and components in a way that meets the guidelines herein and complements the surrounding context.
Figure 33. Historic core design guidelines draw from desirable characteristics of existing buildings.
Figure 34. Appropriate and inappropriate infill building examples.
b. Other Sites within the DMU and TMU Districts.
i. Encourage architecture that emphasizes a human sense of scale, prominent rooflines, fine detailing, and an inviting appearance. The “Northwest” themed architectural style (popular in recent downtown construction – see Figure 35 below) emphasizing the use of natural wood (including heavy timbers), prominent rooflines, accent stonework, and detailed window trimming is encouraged.
Figure 35. Newer commercial buildings emphasize the use of wood and heavy timbers, prominent rooflines, and accent stonework.
ii. No franchise/corporate architecture. Architecture that is defined predominately by corporate identity features (and difficult to adapt to other uses) is prohibited. For example, some fast food franchises have very specific architectural features that reinforce their identity.
iii. Unusual design themes or architectural styles that have no history with Chelan are discouraged.
c. Sites within the DMR and DSF Districts. Encourage architectural styles that are compatible with the generally two-story and vernacular twentieth century architecture.
a. To reduce the scale of large buildings and add visual interest.
b. To enhance the visual character of downtown Chelan.
a. Use of window and/or entries that reinforce the pattern of forty-foot storefront spaces.
b. Use of weather protection features that reinforce forty-foot storefronts. For example, for a business that occupies one hundred twenty feet of frontage, use three separate awnings to break down the scale of the storefronts. Alternating colors of the awnings may be useful as well.
c. Change of roofline per subsection (C)(6) of this section.
d. Use of vertical piers that reinforce storefront pattern.
e. Change in building material or siding style.
f. Other methods that meet the intent of the standards as approved by the director.
Figure 36. Storefront articulation examples.
Departures will be considered by the city provided the design meets the intent of the standards. For example, the proposed articulation may be longer, but if the building features attractive detailing, materials, interesting roofline treatments, and interesting storefront design helps the design fit into the site’s context and contributes to the pedestrian environment and existing/desired character, then perhaps it should be an approved departure.
a. Providing vertical building modulation of at least two feet in depth and four feet in width if combined with a change in siding materials and/or roofline modulation per subsection (C)(6) of this section. Otherwise, the vertical modulation shall be at least ten feet deep and fifteen feet wide, to qualify.
b. Providing horizontal modulation (upper level step backs). To qualify for this measure, the minimum upper level step back shall be at least five feet and the treatment shall be used consistently with other articulation elements or utilized along at least seventy-five percent of the facade.
c. Repeating distinctive window patterns at intervals less than the articulation interval.
d. Providing a covered entry or separate weather protection feature for each articulation interval.
e. Use of vertical piers that reinforce storefront pattern. To qualify for this measure, the piers must project at least two inches from the facade and extend from the ground to the roofline.
f. Change of roofline per subsection (C)(6) of this section.
g. Changing materials and/or color with a change in building plane.
h. Providing lighting fixtures, trellis, tree, or other landscape feature within each interval.
i. Other methods that meet the intent of the standards as approved by the director.
Departures will be considered by the city provided the design meets the intent of the standards. Elements to consider are the level of detailing, quality of building materials, design of storefronts, and integration with, or enhancement of, the surrounding context.
Figure 37. Building articulation example for other nonstorefront commercial facades.
a. Repeating distinctive window patterns at intervals less than the required interval.
b. Providing vertical building modulation. Minimum depth and width of modulation is eighteen inches and four feet (respectively) if tied to a change in color or building material and/or roofline modulation as defined in subsection (C)(6) of this section. Otherwise, minimum depth of modulation is ten feet and minimum width for each modulation is fifteen feet. Balconies may not be used to meet modulation option unless they are recessed or projected from the facade and integrated with the building’s architecture as determined by the director. For example, “cave” balconies or other balconies that appear to be “tacked on” to the facade will not qualify for this option.
d. Providing horizontal modulation (upper level step backs). To qualify for this measure, the minimum upper level step back shall be at least five feet and the treatment shall be used consistently with other articulation elements or utilized along at least fifty percent of the facade.
e. Articulating of the building’s top, middle, and bottom. This includes a distinctive ground floor or lower floor design, consistent articulation of middle floors, and a distinctive roofline.
Departures will be considered by the city provided the design meets the intent of the standards. Elements to consider are the level of detailing, quality of building materials, types of articulated features, and integration with, or enhancement of, the surrounding context.
For articulation of townhouses, see Section 17.14.050(F)(5).
Figure 38. Building articulation example for other nonstorefront commercial facades.
a. Comply with roofline modulation provisions per subsection (C)(6) of this section.
b. Provide a cornice of two parts with the top projecting at least six inches from the face of the building and the bottom part featuring a concave design or projecting at least two inches from the facade, but extending no less than two inches from the facade than the top part (see Figure 39 for examples). The height of the cornice (both parts combined) shall be at least twelve inches for buildings twenty feet or less in height; eighteen inches for buildings greater than twenty feet and less than thirty feet in height; and twenty-four inches for buildings thirty feet and greater in height. Cornices shall not project over property lines, except where permitted on property lines abutting public right-of-way. The cornice line must extend along at least seventy-five percent of the facade.
c. Other decorative cornice line that meets the intent of the standards. See Figures 39 and 40 for examples.
d. Any combination of the options above.
Figure 39. Acceptable cornice examples.
Figure 40. Desirable (left) and undesirable (right) local cornice examples.
a. For flat roofs or facades with horizontal eave, fascia, or parapet, the minimum vertical dimension of roofline modulation is the greater of two feet or one-tenth multiplied by the wall height (finish grade to top of the wall) when combined with vertical building modulation techniques described in subsections (C)(2) through (4) of this section. Otherwise, the minimum vertical dimension of roofline modulation is the greater of four feet or two-tenths multiplied by the wall height.
b. A sloped or gabled roofline segment of at least twenty feet in width and a minimum slope of 6:12. The roofline must include modulated segments at no more than the interval required per the applicable standard above.
Figure 41. Roofline modulation standards.
ii. Contrasting window design (sizes or configurations).
Departures will be considered by the city provided the design meets the intent of the standards. Elements to consider are the level of detailing, quality of building materials, types of articulated features, and integration with, or enhancement of, the surrounding context (considering views from all publicly observable locations within downtown).
Figure 42. Maximum facade width standards and acceptable/unacceptable departure examples. The upper right examples use a change in materials, facade articulation (window styles), and roofline change. The middle right image uses substantial facade and roofline modulation. The lower right does not include any notable articulation or modulation.
D. Building Elements and Details.
1. Intent. To encourage the incorporation of design details and small scale elements into building facades that are attractive at a pedestrian scale.
2. Facade Details Toolbox. All nonresidential and mixed-use buildings shall be enhanced with appropriate details. All new buildings must employ at least one detail element from each of the three categories below for each facade facing a street or public space for each facade articulation interval (per subsections (C)(2) and (3) of this section). For example, a building with one hundred twenty feet of street frontage with a facade articulated at forty-foot intervals will need to meet the standards for each of the three facade segments.
a. Window and/or Entry Treatment.
ix. Other decorative or specially designed entry treatment that meets the intent of the standards as determined by the director.
b. Building Elements and Facade Details.
v. Other details or elements that meet the intent of these standards, as determined by the director.
c. Building Materials and Other Facade Elements.
v. Other details that meet the intent of the standards as determined by the director.
“Custom,” “decorative,” or “hand-crafted” elements referenced above must be distinctive or “one-of-a-kind” elements or unusual designs that require a high level of craftsmanship as determined by the director.
Departures to the standards above will be considered by the director provided the number, quality, and mix of details meet the intent of the standards.
Figure 43. Good storefront detail examples for the Woodin Avenue historic core. The left image includes a decorative use of brick, decorative awning, and decorative kick-plate. The right image uses a steel canopy (Chelan Sports), decorative use of bricks, and decorative window treatments.
Figure 44. Acceptable facade detailing example for outside the historic core. This building uses decorative stone and shinglework, decorative windows, and a decorative entry feature.
g. Other special or unique corner building treatment, other than the use of fabric or vinyl awnings, for pedestrian weather protection at the corner of the building as determined by the director.
All corner building design elements must be sized to be proportional to the building and the size of the applicable intersection, as determined by the director (for example, larger intersections warrant more substantial design treatments).
Figure 45. Clarifying which buildings shall comply with standards.
Figure 46. Desirable building corner examples.
4. Window Design. Buildings shall employ techniques to recess or project individual windows above the ground floor at least two inches from the facade or incorporate window trim at least four inches in width that features color that contrasts with the base building color. Departures will be considered by the director where buildings employ other distinctive window or facade treatment that adds a sense of depth to the facade and/or visual interest to the building.
Figure 47. Acceptable and unacceptable (far right image) window design on upper floors. Note that the two windows on the left are recessed from the facade and all three acceptable examples include trim. The image on the right includes no trim or recess/projection.
5. Year of Construction Plaque. All new commercial and mixed-use buildings must note the year of construction of a building by the installation of a plaque attached to the building. Numbers etched into stone, brick, or concrete may be used in lieu of a plaque. The year of construction is to be noted by numbers not less than six inches high. Other information associated with the building that may be of public interest may be included.
E. Building Materials and Colors.
a. To encourage high quality building materials that reinforce the historic small town character of Chelan.
b. To discourage poor materials with high life-cycle costs.
c. To encourage the use of materials that reduce the visual bulk of large buildings.
Figure 48. Acceptable and unacceptable metal siding examples. Notice the corner and window trim and use of concrete block near the ground level on the left image. The circled area on the right includes metal siding all the way to the ground, which is prohibited.
c. The use of metal siding is prohibited on designated storefront streets.
b. Concrete block may comprise no more than fifty percent of a facade facing a public right-of-way or open space. Departures to this standard will be considered by the city provided design treatments are included to enhance the visual character of the building at all observable scales.
Figure 49. Acceptable and unacceptable concrete block examples. The left example uses a mixture of split-faced colored concrete block and smooth-faced concrete block, together comprising just under fifty percent of the whole facade. The large expanse of smooth-faced concrete block on the right is not desirable for Chelan.
c. Stucco, EIFS, and similar surfaces should not extend below two feet above the ground plane. Concrete, masonry, or other durable material must be used below the two-feet-above-grade line to provide a durable surface where damage is most likely.
Figure 50. Acceptable and unacceptable stucco examples. The left image uses concrete block near the sidewalk, while the Petco maintains stucco to the base of the facade.
e. Back-lit vinyl awnings used as signs.
6. Storefront Building Color. A storefront’s palette should be no more than three colors; one base color, one trim color, and one accent color. Encourage trim and accent colors that contrast with the base color. Specifically, darker base colors with white trim work particularly well. However, lighter base colors can effectively be combined with dark trim colors. Applicants should consult with the Historic Chelan Downtown Association on appropriate facade colors.
a. To avoid untreated blank walls.
b. To retain and enhance the character and identity of downtown Chelan.
b. Any portion of a ground floor wall having a surface area of four hundred square feet or greater does not include a transparent window or door.
Figure 51. Blank wall definition and treatment examples.
e. Special building detailing that adds visual interest at a pedestrian scale. Such detailing must use a variety of surfaces; monotonous designs will not meet the intent of the standards.
For large visible blank walls, a variety of treatments may be required to meet the intent of the standards.
4. Fire walls along property lines are exempt from the above standards, but where they are visible to the public, they shall include horizontal and/or vertical banding or other design treatments to add visual interest to the wall.
Figure 52. Acceptable and unacceptable fire wall treatments. Note the use of horizontal banding in the left image. Plain concrete block as in the right image is not allowed.
G. Energy Efficient Building Design. The following are voluntary provisions intended to encourage energy efficient building design within Chelan.
a. To reduce greenhouse gas emissions resulting from buildings.
b. To encourage high quality energy efficient construction that reduces long-term maintenance costs.
c. To encourage the use of roof design and materials that maximize the energy efficiency of buildings.
2. Residential Buildings. New and remodeled buildings should be designed to meet the Northwest ENERGY STAR Homes Certification Requirements for Single-Family Homes or Multi-Family Homes (link: http://www.northwestenergystar.com/partner-resources/bopmulti/index.html).
3. Commercial or Mixed-Use Buildings. New and remodeled buildings should be designed to earn the ENERGY STAR rating by achieving the rating of seventy-five or higher using the EPA energy target finder tool (link: http://www.energystar.gov/index.cfm?c=new_bldg_design.bus_target_finder).
4. Roof Design. The solar reflectivity index for flat roofs should be a minimum of seventy-eight. The solar reflectivity index for sloped roofs should be a minimum of twenty-nine. (Ord. 1410 § 3 (Exh. B) (part), 2010).
1. Purpose. This section provides supplemental direction for the design of new residential developments consistent with the goals and policies of the Chelan downtown master plan.
2. Applicability. Each subsection herein provides standards that apply to a particular type of housing within the downtown planning area. The provisions herein supplement the standards set forth in Section 17.14.020. Triplexes and townhouses are also subject to the provisions of Sections 17.14.030 and 17.14.040 unless otherwise noted.
d. To provide usable yard space for residents.
a. Clear and obvious pedestrian access between the sidewalk and the building entry is required for new homes.
b. All new houses shall provide a covered entry with a minimum dimension of four feet by six feet. Covered entries may project up to six feet into the front yard per Section 17.14.020(C)(3).
Figure 1. Single-family design requirements.
3. Garage Placement and Design.
a. Where lots abut an alley, the garage or off-street parking area is encouraged to take access from the alley.
b. The garage face shall occupy no more than fifty percent of the ground-level facade facing the street.
c. Garages shall be set back at least twenty feet from the front property line.
4. Driveway Standards. See Section 5 of the City of Chelan Development Standards Manual for applicable standards.
5. Minimum Usable Open Space. All new single-family residences shall provide a contiguous open space equivalent to ten percent of the lot size. Such open space shall not be located within the front yard. The required open space shall feature a minimum dimension of fifteen feet on all sides. For example, a six-thousand-square-foot lot would require a contiguous open space of at least six hundred square feet, or twenty feet by thirty feet in area. For lots in the DMR District where there is more than one single-family residence on the lot, each residence shall have access to a usable open space with minimum dimensions of fifteen feet on all sides. Driveways shall not count in the calculations for usable open space.
All single-family additions shall not create or increase any nonconformity with this standard.
Figure 2. Open space requirements for alley-loaded lots.
C. Duplex and Triplex Design Standards.
1. Intent. Duplexes and triplexes should be designed similar in nature to single-family homes and shall feature a visible entry and windows facing the street. The visibility of driveways and garages should be minimized and sufficient private open space should be provided.
c. Duplexes on corner lots shall place pedestrian entries on opposite streets (applicable to new buildings only).
Figure 3. Diagram illustrating some duplex design standards.
D. Accessory Dwelling Units (ADU).
a. To provide infill housing opportunities downtown.
b. To provide affordable housing options downtown and all residential zones.
c. To provide an opportunity for rental income for downtown property owners.
a. ADU Entrance. The ADU entrance shall be subordinate (set back) to the principal dwelling unit entrance. The ADU entrance shall be less visible from the street view of the principal dwelling than the main entrance of the principal dwelling unit.
j. Detached accessory dwelling units must be screened from neighboring properties with a six-foot height solid visual barrier where necessary to protect abutting property owners’ privacy, as determined by the director.
3. Standards for an Attached ADU.
v. Front Facade. The front facade of the principal dwelling shall not be significantly altered to accommodate an ADU.
Figure 4. Attached ADU example/standards.
4. Standards for a Detached ADU (DADU).
f. The maximum width of the DADU shall be seventy-five percent of the width of the lot, including all projecting building elements such as bay windows and balconies.
a. To provide an opportunity for small, detached housing types clustered around a common open space.
b. To ensure that cottage developments contribute to the overall character of downtown residential areas.
c. To provide for centrally located and functional common open space that fosters a sense of community.
d. To provide for semi-private area around individual cottages to enable diversity in landscape design and foster a sense of ownership.
e. To minimize visual impacts of parking areas on the street and adjacent properties and the visual setting for the development.
f. To promote conservation of resources by providing for clusters of small dwelling units on a property.
2. Description. Cottage housing refers to clusters of small detached dwelling units arranged around a common open space.
3. Lot Configuration. Cottages may be configured as condominiums or fee-simple lots provided they meet the standards herein.
4. Density Bonus. Due to the smaller relative size of cottage units, each cottage shall be counted as one-half a dwelling unit for the purpose of calculating density. For example, a cluster of six cottages would be equivalent to three dwelling units.
5. Table of Dimensional Standards for Cottages.
6. Units in Each Cluster. Cottage housing developments shall contain a minimum of four and a maximum of twelve cottages located in a cluster to encourage a sense of community among the residents. A development site may contain more than one cottage housing development.
7. Windows on the Street. Transparent windows and/or doors are required on at least fifteen percent of the facades (all vertical surfaces) of all cottages facing the street and common open space. Departures may be permitted for cottages where this standard applies to two or more facades, provided the design meets the intent of the standards.
8. Parking and Driveway Location and Design.
g. No more than one driveway per cottage cluster shall be permitted, except where clusters front onto more than one street.
9. Common Open Space Requirements.
e. Open space shall include at least one courtyard, plaza, garden, or other central open space, with access to all units. The minimum dimensions of this open space are fifteen feet by twenty feet.
10. Required Private Open Space. Required private open space shall be adjacent to each dwelling unit, for the exclusive use of the cottage resident(s). The space shall be usable (not on a steep slope) and oriented toward the common open space as much as possible, with no dimension less than ten feet.
11. Porches. Cottage facades facing the common open space or common pathway shall feature a roofed porch at least eighty square feet in size with a minimum dimension of eight feet on any side.
Alternative design treatments will be considered by the director provided the design treatments provide visual interest to the pedestrian.
Figure 6. Typical cottage housing layouts.
Figure 7. Cottage housing examples.
a. To ensure that townhouse developments enhance the pedestrian-oriented character of downtown streets.
b. To provide adequate open space for townhouse developments.
c. To reduce the impact of garages and driveways on the pedestrian environment.
d. To reduce the apparent bulk and scale of townhouse buildings compatible with the established character of downtown Chelan.
e. To promote architectural variety that adds visual interest to the neighborhood.
Figure 8. Desirable townhouse example. With units fronting on the street and garages placed to the rear accessible from an alley or shared driveway.
d. Planting strips with no dimension less than four feet are required adjacent to the primary entry of all dwelling units. This includes townhouses located to the rear of lots off an alley or private internal drive.
d. Internal Drive Aisle Standards.
iii. Upper level building projections over drive aisles are limited to three feet, and must comply with provisions in subsection (F)(3)(d)(ii) of this section.
Figure 9. Good and bad examples of garage/entry configurations. The left example features a landscaped area and a trellis to highlight the entry. In the middle image, the balconies and landscaped areas deemphasize the garage. In the right image, the lack of landscaping is a glaring omission.
d. Pea patch space meeting the requirements of Section 17.14.030(C)(5)(e).
a. Townhouse Articulation. Townhouse buildings shall comply with multi-family building articulation standards as set forth in Section 17.14.040(C)(4), except that the articulation intervals shall be no wider than the width of units in the building. Thus, if individual units are fifteen feet wide, the building shall include at least three articulation features per Section 17.14.040(C)(4) for all facades facing a street, common open space, and common parking areas at intervals no greater than fifteen feet.
iv. Other design treatments that add variety or provide special visual interest. While the variable use of color on buildings can be effective in reducing the perceived scale of the building and adding visual interest, color changes alone are not sufficient to meet the intent of the guidelines.
Figure 10. Acceptable townhouse configuration employing the repetition with variety concept.
Figure 11. An acceptable townhouse building. Note the landscaped front yards and individual walkways and entries. The internal units each have distinct but identical windows and roof forms. The outside unit is differentiated through the use of building materials, window design, unit size, and facade detailing.
(Ord. 1556 § 8 (Exh. G), 2019; Ord. 1410 § 3 (Exh. B) (part), 2010).
“Building articulation” means the giving of emphasis to architectural elements (like windows, balconies, entries, etc.) that create a complementary pattern or rhythm, dividing large buildings into smaller identifiable pieces. See Section 17.14.040(C) for applicable standards.
“Condotel” refers to a building that is used both as a hotel and a condominium.
“Cottage housing” refers to clusters of small detached dwelling units arranged around a common open space.
“CPTED” refers to “crime prevention through environmental design,” which is a multi-disciplinary approach to deterring criminal behavior through environmental design. CPTED strategies rely upon the ability to influence offender decisions that precede criminal acts.
“Landscaped street” refers to a segment of a street envisioned to have or maintain landscaped building setbacks along the street. See Figure 2 for the location of designated landscaped streets and Section 17.14.020(D)(4) for the description and applicable standards for properties fronting on designated landscaped streets.
“Partial floor” refers to the space under a gabled or hipped roof where a horizontal line intersecting the roof decking and the exterior wall is no more than five feet above the floor level of the top floor.
Pedestrian-Oriented Open Space (or Pedestrian-Oriented Space). See Section 17.14.030(C)(2)(a) for the definition of “pedestrian-oriented open space” and Section 17.14.030(C)(3) for applicable design criteria.
“Roofline modulation” means variation in roof form. See Section 17.14.040(C)(6) for provisions.
“Secondary street” refers to a segment of a street in a mixed-use district where there is an option for storefronts or landscaped setbacks along the street and ground floor residential or commercial uses. See Figure 2 for the location of designated secondary streets and Section 17.14.020(D)(3) for the description and applicable standards for properties fronting on designated secondary streets.
“Solar access” means the availability of (or access to) unobstructed, direct sunlight.
“Solar reflectance index (SRI)” is a measure of the roof’s ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. For example, the standard black has a temperature rise of 90 degrees Fahrenheit (50 degrees Celsius) in full sun, and the standard white has a temperature rise of 14.6 degrees Fahrenheit (8.1 degrees Celsius). Once the maximum temperature rise of a given material has been computed, the SRI can be computed by interpolating between the values for white and black. Materials with the highest SRI values are the coolest choices for roofing. Due to the way SRI is defined, particularly hot materials can even take slightly negative values, and particularly cool materials can even exceed 100.
“Storefront street” refers to a street or segment of a street where envisioned to have storefronts placed up to the edge of the sidewalk. See Figure 2 for the location of designated storefront streets and Section 17.14.020(D)(2) for the description and applicable standards for properties fronting on designated storefront streets.
“Transparent window” refers to a window that is capable of transmitting light so that objects or images can be seen as if there were no intervening material variation in roof form. (Ord. 1410 §§ 3, 10 (Exh. B) (part), 2010).
