Where open-ended influent pipes cannot be avoided, safety facilities shall be constructed, acceptable to the Borough Engineer.
Storm sewers and culverts shall be sized, based on the design storm, to provide a minimum one-foot of freeboard at inlets, manholes, and embankments.
Stormwater Detention.
Stormwater detention facilities will be required if one of the following conditions is present:
Runoff from the development would exceed the capacity of downstream stormwater facilities.
Runoff from the development would increase the peak runoff by one cubic foot per second (CFS) or more from the existing conditions. One single-family dwelling not requiring subdivision is exempt from this requirement.
Runoff from a proposed parking facility or building would increase the peak runoff from the existing condition.
The design criteria for the stormwater detention facility shall be agreed upon by the Borough Engineer. Developers are encouraged to investigate all measures to reduce and detain water, for discharge at a delayed rate or ground water recharge. All reasonable methods will be considered.
Basins or Other Management Facilities.
The design of all stormwater basins must be approved by the Borough Engineer based upon their effectiveness for achieving stormwater control objectives, water quality enhancement, groundwater recharge, ease of maintenance, safety considerations, and conformance to landscape and surrounding uses and activities.
Basins shall be installed prior to any earth moving in the areas that drain into them. The phasing of their construction shall be noted on the plan.
Where basins are required by Borough, adequate maintenance guarantees, indemnification, insurance, and security shall be provided by the applicant and approved by the Borough.
Where feasible, basins shall be developed jointly by abutting landowners, or regionally by several developing landowners.
If a basin is to remain in private ownership, the applicant shall assure proper maintenance in the form of a recorded deed restrictions, bonds, or escrows, as approved by the Borough. The Borough has the right to enter the lot to perform any required maintenance that has not been performed or carried out in a timely manner by the lot owner. The lot owner shall be liable for the cost of any maintenance which is performed by the Borough, the Borough shall place a lien on the property for all costs if the owner refuses to pay them.
Developers are encouraged to use best management practices (BMPs), if appropriate, to provide for additional water quality improvement and groundwater recharge. The methods and design criteria of stormwater controls or BMPs that may be used are described in the Borough Stormwater Management Ordinance [Chapter 23], as amended, and the "Pennsylvania Stormwater Best Management Practices Manual," December 2006, as amended.
A dam safety permit under 25 Pa. Code, Chapter 105, as issued by the Department of Environmental Protection is required for all basins that have dams on a natural watercourse where:
The contributory drainage exceeds 100 acres.
The greatest depth of the impounded water measured at the upstream toe of the dam at maximum storage exceeds 15 feet.
Impoundment storage capacity at the maximum storage elevation exceeds 50 acre-feet.
A dam safety permit under 25 Pa. Code, Chapter 105, as issued by the DEP is required for basins not on a natural drainage course where the greatest depth at the upstream toe of the dam at maximum storage exceeds 15 feet or the impounding storage capacity at a maximum storage elevation exceeds 50 acre-feet.
Facility Design.
Basins shall be designed based upon the appropriate hydrologic and hydraulic calculations which have been reviewed and approved by the Borough Engineer. Basin storage capacity must be sufficient to meet the requirements of this chapter.
Basins shall incorporate curvilinear reflective of surrounding topography.
Minimum grades of stormwater basins shall be 2%. Grades of less than 2% may be permitted when designed to convey water as approved by the Borough Engineer. The maximum basin side slopes shall be three to one.
The sizing and scale of the basin shall be compatible with other elements of the site.
Structural Improvements.
Outlet works and emergency spillways shall be sized to cause detention of and passage of design inflow so as to maintain a two-foot freeboard for storms up to a twenty-five-year, twenty-four-hour design storm and a one-foot freeboard for storms up to the one-hundred-year, twenty-four-hour storm.
Emergency spillways, where considered necessary by the Borough Engineer, shall be sized and located to permit the safe passage of stormwater flows from a one-hundred-year storm. The maximum velocities in vegetated spillways excavated in undisturbed soil shall be checked based upon the velocity of peak flow in the emergency spillway during an assumed clogged primary outlet condition. Where maximum velocities exceed design standards contained in the Erosion and Sediment Pollution Control Manual, suitable lining shall be provided. All emergency spillways placed on fill materials shall be lined. Lining for emergency spillways shall incorporate native colors and materials where possible including mono slab revetments, grass pavers and native stone.
Inlet Structures. The invert of the inlet pipe into a basin shall be six inches above the basin floor or lining so that the pipe can adequately drain after rain storms. Inlets shall discharge into areas of the basin that slope toward the outlet structure. Inlet and outlet structures shall be located at a maximum distance from each other in order to promote water quality benefits. The Borough Engineer may require a rock filter or rock filled gabion for entrapping sediments carried in stormwater if sufficient separation of inlet and outlet structure cannot be achieved.
Energy Dissipators. Devices to dissipate or spread stormwater flow shall be installed at points where pipes or drainageways drain into or from a basin. Energy dissipators shall comply with criteria in Hydraulic Engineering Circular No. 15, Design for Stable Channels with Flexible Linings, published by the Federal Highway Administration, or the DEP Erosion and Sediment Pollution Control Program Manual.
Outlet Structures. To minimize clogging and to facilitate cleaning, outlet pipes shall have an internal diameter of at least 18 inches and a minimum grade of 1%. Anti-seep collars shall be located on all outlet pipes. All principal outlet structures shall be built with reinforced concrete with watertight construction joints. The developer shall consider the use of architecturally treated concrete, stucco, painted surface or stone facade treatment for enhancing the outlet structure. Outlet pipes shall be constructed of reinforced concrete with rubber gaskets in conformance with AASHTO M170, M198 and M207. Child proof trash racks or anti-vortex devices shall be constructed at all outlets and designed to facilitate cleaning and avoid clogging caused by debris.
Stabilization. Prior stabilization, structures including stilling basins, energy dissipators, and channel lining shall be constructed at the outlets of all basins and emergency spillways. The stabilization structures shall control water to avoid erosion, reduce velocities of released water and direct water so that it does not interfere with downstream activities.
Wet Basins. Existing ponds or permanent pool basins can be used provided that they meet the following criteria:
The minimum permanent pool level shall be maintained to allow sufficient depth throughout the year to reduce the growth of unwanted vegetation and mosquitoes.
The pond must be of sufficient size to allow the appropriate aquatic community needed to maintain a healthy pond ecology.
The applicant shall submit wet basin planting schedule and method for mosquito control.
The design of a detention facility with a permanent pool shall include the determination of the proposed site's ability to support a viable permanent pool. The design shall take into account for such factors as the required rate and quality of dry weather inflow, the quality of stormwater inflow, seasonal and longer term variations in groundwater table, and effects of suspected pollutant loadings.
Basins with Gabion Dams. Gabion outlet control structures for stormwater basins shall be filled with rocks six inches to eight inches in diameter. Outlet flow through the gabions shall be calculated by the following equation:
Q = (0.40 x h x 2)/L
Height of ponding in basin (feet)
Width of stone structure (feet)
Average structure thickness (top of berm + bottom of berm)/2
Underground Basins. Underground stormwater detention systems can be used where sufficient space is not available for above-ground systems or where underground storage systems are recharging groundwater.
Developers are encouraged to use best management practices (BMPs), if appropriate, to provide for additional water quality improvement and groundwater recharge. The methods and design criteria of stormwater controls or BMPs that may be used are described in the Borough Stormwater Management Ordinance [Chapter 23], as amended, and the "Pennsylvania Stormwater Best Management Practices Manual," December 2006, as amended. In evaluating potential stormwater BMPs, the order of preference shall be as follows:
Infiltration BMPs.

Artificial wetlands.
Minimum first flush detention or dual purpose detention (where appropriate).
All plans showing the proposed storm sewer construction must be accompanied by a complete design prepared by a registered engineer.
When subdivisions or land developments are submitted to the Borough Engineer for approval in sections, a complete storm sewer design for the proposed subdivision and land development shall be submitted. The proposed design must include the entire tract and not a portion.
If only a section of a subdivision or land development is contemplated for construction, the applicant's engineer shall show how he proposes to handle stormwater from this section in order to prevent damage to adjacent properties. If temporary construction is required, the applicant's engineer shall include such structures in the plan submitted.
In the event such temporary measures cannot ensure protection to adjacent properties, then the main outfall line of the storm sewer shall be included as part of the construction for the proposed section.
Widths and locations of easements and rights-of-way shall be determined by the Borough Engineer or the appropriate Authority or utility company for all utilities, including stormwater facilities, and shall be governed by the requirements herein.
Easements and required front, side or rear yards may co-occupy the same land.

Final plans for minimizing erosion and sedimentation as approved will be incorporated into the agreement and bond requirements as required under Part 5 of this chapter.
The approval of plans and specifications for the control of erosion and sedimentation shall be concurrent with the approval of the final plans of subdivision or land development, and become a part thereof.
At the time that a building permit is applied for, a review shall be conducted by the Borough Engineer to ensure conformance with the plan as approved. During the construction, further consultative technical assistance will be furnished, if necessary, by the Borough Engineer and the Montgomery County Conservation District. During this development phase, the Borough Engineer shall inspect the development site and enforce compliance with the approved plans.
Permission for clearing and grading prior to recording of plans or receipt of final plan approval may be obtained under temporary permits or other conditions satisfactory to the Borough, at the applicant's risk.
In the event the developer proceeds to clear and grade prior to recording plans, without satisfying conditions specified under Subsection 1D(4), Borough Council may revoke the approval of the preliminary plan.
Bridges and culverts shall be designed to meet current PennDOT standards to support expected loads and to pass design stormwater flows. They shall be constructed to the full width of the planned cartway. Allowance for sidewalk must also be made, if required by the Borough.
Where county-owned roads or bridges are involved, the County Engineer must review and approve all proposals.
It is unlawful to construct any dam or other water obstruction, or to make any change in or addition to, any existing water obstruction, or in any manner change or diminish the course, current, or cross-section of any stream or body of water, without first having made written application to and obtained a permit or consent in writing from DEP.
The following information is required: drawings to include location plan; cross-section of present bridge if one exists; profile of stream for a reasonable distance above and below bridge site, showing slopes of bed, normal water surface and flood water surface. If the bridge is on a skew, give the angle of the center line of the bridge with the direction of the line of flow. In addition, the following information is required for new bridge construction: the total drainage area above the bridge site; description of watershed; length of stream from source to bridge site and to the mouth; character of stream bed and banks; extent and depth of overflow during floods; effect of previous floods upon bridges, their span and clearance; and whether bridge will be within backwater influence of parent stream.
A complete set of structural computations and drawings shall be submitted with plans involving construction of bridges and culverts.
Permanent monuments shall be indicated on the record plan. All monuments shall be constructed of precast concrete or durable stone with metal insert(s), and be four inches square with at least 20 inches extending below ground level, or an alternate design approved by Borough Council. Street right-of-way reference monuments shall be located on the right-of-way lines at corners, angle points, beginning and end of curves, and as otherwise required by the Borough Engineer for all new and existing streets. They shall be placed after a new street and/or lot grading has been completed. The center line of all new streets shall be marked with spikes (P.K. nails) and referenced to permanent monuments or structures. Certified copies of this reference information shall be given to both the Borough Engineer and the Borough Office. When final lot grading has been completed and before the issuance of occupancy permits, permanent monuments shall be set by the subdivider, developer, or builder, at all lot corners and angle points, and at all street intersections and intermediate points as may be required.
Lot Pin Requirements. All lots upon which construction is planned shall be temporarily staked or pinned, or permanently monumented and certified to such by a registered surveyor for the owner, subdivider, builder, or developer, before issuance of a building permit. A signed certificate of compliance must be submitted with a building permit application. Temporary stakes or pins with a surveyor's ribbon attached may be acceptable on existing lots where construction of an accessory building or an addition to the primary structure is proposed, only if construction is begun within 30 days of the certificate of compliance date. Temporary stakes or pins shall remain in place until witnessed and accepted by the Borough Building Inspector. Prior to final approval of a new subdivision plan, all new lot corner markers shall be marked with a minimum 5/8 inch diameter metal pin extending at least 24 inches into the ground and at least one inch revealed above the ground surface, or an equivalent metal marker, approved by the Borough Engineer. Upon completion of construction and final grading, pins shall be replaced with permanent monuments as described in Subsection 1.
Original Monuments. In situations where they may be of legal or historical importance, the original monuments and marks must not be destroyed, defaced, hidden, or possible confused by creating new monuments and marks unless absolutely necessary, e.g., the originals are decayed, destroyed, or unsafe. In some cases, to be determined by the Borough Engineer, new monuments shall be set as a reference or witness to the original monument to avoid disturbing the original. When in the opinion of the Borough Engineer, the angle point falls in a location that is not appropriate to set a concrete monument, a written request for a waiver shall be submitted for consideration by Borough Council.
Bench Marks. The Borough elevations are based on the USGS datum. Location and elevation is available to all engineers and surveyors upon request to the Borough Engineer's Office. All contours and elevations shown on the plan must be based on this system.
Minimum cartway width shall be 10 feet.
When paved, pavement shall conform to the Borough of Hatboro Specifications and Design Standards, incorporated herein by reference and as may be amended from time to time by Resolution of Borough Council.

Placed on top of the six inches of crushed stone shall be an interlinked porous pavement constructed of fiber reinforced polyethylene or concrete grass pavers. All void areas shall be filled with topsoil and seeded with an appropriate grass mix.
Markings or appropriate form of identification shall be placed at the entrance to the emergency accessway. If necessary, break away bollards shall be installed at each end of the emergency accessway.
Emergency accessways shall be maintained through properly recorded easements or deed restrictions which at a minimum prohibit the planting of any vegetation except grass within the accessway.
The applicant shall provide and install street lights in locations determined to be necessary by the Borough. The Borough may also require that street lights be provided and installed by the applicant along private streets.
The design of the street light fixtures and poles shall be subject to approval by the Borough. Where a predominant design of luminaries and poles has been established, the Borough may require that such design be used in new lights.
Lighting shall be designed in accordance with standards developed by the electric utility provider. The Borough may require that lighting meet standards recommended in the IESNA Lighting Handbook. Construction of highway lighting shall be in conformance with PennDOT Specifications Publication 408, most recent edition.
Permanent outdoor lighting is required in places where public health, safety and welfare are potential concerns. The outdoor lighting section shall protect drivers and pedestrians from the glare of non-vehicular light sources that shine into their eyes and thereby impair safe traverse, protect neighbors and the night sky from nuisance glare and stray light from poorly aimed, placed, applied, maintained or shielded light sources.
The requirements herein apply where outdoor lighting is required by Borough ordinance, is otherwise required by the Borough, or is proposed by the applicant. The requirements contained herein also apply to sign, architectural, and landscape lighting. The requirements herein do not apply to streetlights and traffic lights located in the public right-of-way and owned by the Borough of Hatboro.
Lighting plans shall be submitted for review and approval of any lighting installation in connection with a land development application for any use identified in this section.
Lighting plans shall include the following:
A site plan, complete with all structures, parking spaces, building entrances, traffic areas (both vehicular and pedestrian), vegetation that might interfere with lighting, and adjacent use(s) that might be adversely impacted by the lighting, and containing a layout of all proposed fixtures by location and type.
Description of the proposed equipment shall be included, including fixture catalog cuts, photometrics, glare reduction devices, lamps and mounting heights.
When requested by Borough Council, the applicant shall also submit a visual impact plan that demonstrates appropriate steps have been taken to mitigate on-site and off-site glare, including, but not limited to, a plot plan with a matrix of the calculated footcandles with measurements 10 feet into the neighboring properties, including those on the opposite side of a public right-of-way or public roadway, at five feet above ground.
Notification must be sent to the Borough Engineer before any post-approval alterations to lighting plans or intended substitutions for approved lighting equipment are made. Post-approval alterations or intended substitutions to the approved lighting plan must meet the requirements of the originally approved plan.
All lighting fixtures for off-street parking areas, off-street loading areas, driveways and for safety of persons and property must meet IESNA full cutoff.
In no event shall light fixtures exceed 15 feet in height, including the mounting base.
[Amended by Ord. 1032, 5/23/2016]
All light fixtures shall contain lenses that focus light directly beneath the light fixture and shall not permit direct glare into nearby public or private properties.
In no case shall spill-over illumination more than 0.5 footcandle at ground level exist on any nonresidentially zoned or used property when measured, line of sight, at the property line of the aggrieved property.
In no case shall spill-over illumination more than 0.1 footcandle at ground level exist on any residentially zoned or used property when measured, line of sight, at the property line of the aggrieved property.
Architectural lighting, as defined by this section, shall be aimed or directed so as to preclude light projection beyond the immediate object or objects intended to be illuminated. All such lighting shall be extinguished between the hours of 10:00 p.m. and 6:00 a.m.
Glare control shall be accomplished primarily through the proper selection and application of lighting equipment. Only after those means have been exhausted shall vegetation, fences and similar screening methods be considered acceptable for reducing glare.
The landowner is responsible if found to be noncompliant to the lighting plan approved by the Borough Council. The Borough may conduct a post-installation inspection to verify compliance to the approved plan. After installation, the Borough, by way of an authorized enforcement officer, may require the landowner, at the landowner's expense, to make adjustments, remedial measures, or other means to comply with the approved lighting plan.
Notwithstanding the installation date or pre-existing conditions of a lighting fixture or arrangement, if the Borough determines that the standards set forth are not met, the Borough, by way of an authorized enforcement officer, may require the landowner, at the landowner's expense, to make adjustments, remedial measures, or other means to comply with the lighting standards.
Notwithstanding the above requirements of this section, if at any time the Borough deems a lighting fixture or arrangement to be a potential safety hazard or nuisance, it may, at the landowner's expense, require the landowner to make adjustments, remedial measures, or other means to mitigate or prevent the potential hazard or nuisance.
The measurement of the amount of illuminance, in footcandles, shall be at the spot where the lighting fixture or arrangement is causing the potential nuisance.
The Borough reserves the right to conduct post-construction inspections to confirm all outdoor lighting fixtures and arrangements, including architectural lighting, comply with the ordinance standards.
Street Signs. The developer shall erect at every intersection a street sign or street signs having thereon the names of the intersecting streets. At intersections where streets cross, there shall be at least two such street signs and at the intersections where one street ends or joins another street, there shall be at least one sign. Street signs shall be erected before the first dwelling on the street is occupied. Temporary street signs may be erected with the permission of Borough Council. Any temporary signs will be replaced prior to roadway dedication. Street sign letter size shall conform to standards established pursuant to the Americans with Disabilities Act. Street sign color and design shall reflect the style prevailing in the Borough as interpreted by the Borough Engineer.
Street Names. Street names shall be determined in consultation with the Borough. Street names shall bear a reasonable relationship to significant natural features or history of the community. Efforts shall be made to reduce the occurrence of similar names or similar sounding names within the Borough or postal delivery area.
All street trees shall be selected and installed to the standards contained in the Borough Shade Tree Regulations [Chapter 25, Part 1].
All other required planting shall be in accordance with the Borough of Hatboro Specifications and Design Standards, incorporated herein by reference and as may be amended from time to time by Resolution of Borough Council.
The location, dimensions, and spacing of required plantings shall be adequate for their proper growth and maintenance taking into account the sizes of such plantings at maturity and their present and future environmental requirements and tolerances including wind, moisture, sunlight, pests and diseases.
Plantings shall be selected and located where they will not contribute to conditions hazardous to public safety. Such conditions include, but are not limited to, public street rights-of-way, underground and above ground utilities, and sight triangle areas required for unobstructed views at street intersections.
Plant Specifications. All plants shall meet the standards set forth in the Borough of Hatboro Specifications and Design Standards, incorporated herein by reference and as may be amended from time to time by Resolution of Borough Council.
Required plant material shall be perpetually maintained to achieve the required visual effect of the buffer or screen. It shall be the ultimate responsibility of successive landowners to ensure that the required plantings are properly maintained. Dead or diseased plant materials shall be removed or treated properly by the landowner and replaced during the next growing season.
Safety. All sight triangles shall remain clear, and any plant materials that could endanger safety such as unstable limbs shall be removed and the plant materials shall be replaced if necessary. It shall be the responsibility of all property owners to maintain all plantings and architectural elements to ensure a safe environment.
Maintenance guidelines for the plantings are encouraged to be published by the planting plan designer, to be used by grounds maintenance personnel.
Replacement. Any tree or shrub which dies within 18 months of planting shall be replaced by the current landowner or developer. Any tree or shrub that within 18 months of planting is deemed, in the opinion of Borough, not to have survived or not to have grown in a manner characteristic of its species, shall be replaced. Substitutions for certain species of plants may be made with the approval of the Borough.
Landscaping shall also be planted around all detention basins, except in locations where such landscaping would obstruct stormwater flows, emergency spillways or sight distance.
