In addition, the location of public service facilities as outlined in a capital improvement plan or official map shall be considered in locating and planning development.
A. 
Proposed land developments and subdivisions shall address the opportunities and limitations present on a site and its adjacent surroundings. Site opportunities shall be maximized to enhance the overall quality of the development and steps shall be taken to lessen potential negative impacts upon a site and the surrounding properties. The impacts of the proposed development on the natural environment and surrounding land uses shall be given a high priority and made an integral part of the overall design for the land development and subdivision. The following site organization guidelines shall be used:
(1) 
Site improvement layout. Building placement shall be functionally compatible with the site's topography, existing vegetation, and surrounding land uses, taking into account energy conservation, solar access, and pertinent natural features, as described below in § 260-27A(2), Existing natural features.
(2) 
Existing natural features. Existing natural features shall be recognized and integrated into the site layout. Existing natural features, including, but not limited to, streams, steep slopes, floodplains and floodways, wetlands, unique habitat, woods and similar natural resources shall be incorporated into the overall site plan to strengthen the unique quality of the land.
(3) 
Open space. The placement of open space and preservation of scenic views shall be a fundamental part of the development design. Open space lands shall provide for a variety of benefits including recreation, natural resource protection, stormwater management, water quality improvement and protection, air purification, carbon sequestration, scenic views and vistas, and effective buffers between different land uses.
(4) 
Circulation. Movement within a site and access to the site shall consider the safety and convenience of various types of users, not just vehicles. Cross access by various types of users, including but not limited to pedestrians, bicycle, those with limited or alternative mobility such as wheelchairs, and motor vehicles between properties and joint access shall be considered, in order to improve multimodal circulation.
(5) 
Relationship to surrounding uses. The proposed design shall complement positively to surrounding uses through building setbacks, buffers, and separation of uses. Various potential negative impacts upon surrounding land uses, including but not limited to noise, light, and loss of privacy, shall be mitigated.
(6) 
Sustainable development. The development of a site shall use construction methods and building materials that reduce energy, water, and fuel consumption needs of the property, while also considering opportunities to utilize renewable energy sources, and conserve and reuse water resources. For applications considered major plans under this chapter, the applicant shall provide a cost statement providing performance measures, including a ten-year cost evaluation of the energy performance of the systems the applicant proposes to employ, as well as a ten-year cost evaluation of alternative methods to utilize on-site renewable energy sources, and conserve and reuse water resources.
(7) 
Health hazards. The configuration of a subdivision or land development shall reduce potential health and safety hazards to the future users of the subdivision or land development and to the community as a whole.
A. 
Lot size. All lots shall be no smaller than the minimum lot area requirements of the applicable zoning classification and be generally sufficient in size and shape to adequately accommodate the development or use proposed for it. Lots that contain natural restrictions, including, but not limited to, wetlands, water bodies, steep slopes, or other similar features shall be large enough to provide suitable area for the intended use of the lot without requiring encroachment upon natural amenities. Lots with existing or planned public improvements, such as fuel pipe lines, underground utilities, stormwater detention basins, high voltage power lines, or other similar facilities, shall be of adequate size to allow sufficient room for the intended use of the lot without requiring encroachment on the public facilities or easements for the installation, maintenance, repair and replacement of such facilities and improvements.
B. 
Lot shape. Every lot shall contain a building envelope that complies with the requirements of the applicable zoning classification in Chapter 295, Zoning, of the Township Code and is suitable for the type(s) of development proposed.
C. 
Corner lots. Corner lots shall meet lot frontage requirements on two streets.
D. 
Rear or flag lots. Rear or flag lots shall not be permitted.
E. 
Reverse frontage lots. Reverse frontage lots shall not be permitted.
F. 
Lot lines. Lot lines shall be drawn parallel, concentric, at right angles, or radial to the street right-of-way, unless not feasible or undesirable due to existing permanent, natural or man-made features. Where possible, lot lines shall coincide with abutting lot lines and lot lines across streets.
G. 
Lot lines shall follow municipal and county boundaries rather than cross them.
H. 
Building lines. Building lines for all lots shall be in conformance with the minimum front, side and rear yard setback line requirements of the applicable zoning district.
I. 
Lot numbers. For the purpose of development, each subdivision may have an overall system of lot numbers, the number one being assigned to a lot in the first section to be developed. (Such system of lot numbers shall not be confused with the regular house or building numbering system based on a Township-wide plan.)
J. 
Building numbers. House or building numbers shall be assigned by the Township based on an overall street plan. Numbers will be assigned in such a way as to allow for vacant parcels and future development.
A. 
The Board of Commissioners shall determine the need for additional community facilities to serve the proposed subdivision or land development and shall determine which, if any, community facility or facilities shall be provided. Examples of such facilities include but are not limited to illuminated crosswalks, tot-lots, a gazebo, trail, a pedestrian path to a recreation facility, or an electrical facility or access thereto. Where identified in a Township, county, or state trail or open space plan, a trail shall be the preferred amenity.
B. 
Where identified in a duly adopted Township Comprehensive Plan, Township Revitalization Plan, or Township Official Map, or if otherwise deemed necessary or desirable by the Board of Commissioners upon consideration of the particular type of development proposed, and especially in large-scale residential developments, the Board of Commissioners may require the dedication or reservation of such areas or sites of an extent and location, as determined by the Board of Commissioners, as is suitable to service the needs created by the development for parks, schools, roads, emergency services, and other facilities to serve the community.
C. 
Areas dedicated or reserved for such open space or community facilities shall be adequate to provide for building sites, related activity areas, landscaping and off-street parking as appropriate to the use proposed.
A. 
Applicants shall provide and dedicate open space, including appropriate recreation facilities and trails, in accordance with Chapter 295, Zoning, of the Township Code.

The Township, at the time of entering upon such common facilities for the purpose of maintenance, shall file a notice of such lien in the office of the Prothonotary of Montgomery County, upon the properties affected by such lien.
A. 
Preservation of existing vegetation.
(1) 
All subdivisions and land developments should be laid out in such a manner as to minimize the removal and/or disturbance of healthy trees, shrubs, and other vegetation on the site. Special consideration shall be given to mature specimen trees and ecologically significant vegetation.
(2) 
Removal or disturbance of vegetation in environmentally sensitive areas, including wetlands, and riparian corridors, shall be undertaken only as permitted in §§ 260-35 and 260-36 below to minimize the adverse effects of such actions.
(3) 
The applicant shall prove to the satisfaction of the Board of Commissioners that vegetation removal is minimized. A written document or plan shall be performed by a registered landscape architect or other qualified professional showing that no more desirable layouts are possible and no alternative clearing or grading plan would reduce the loss of mature trees, tree masses, and woodlands.
(4) 
Each freestanding mature tree, tree mass, or woodland on the site shall be designated "to remain" or "to be removed" on the existing features plan, pursuant to § 260-15C(7) above and in accordance with the following criteria:
[Amended 12-16-2020 by Ord. No. 2415-20]
(a) 
Trees 100% dead shall be designated "to be removed."
(b) 
Measures shall be taken to preserve live trees, especially unique or specimen trees, as well as trees 24 inches dbh or greater. Examples of such measures are:
[1] 
Rerouting proposed overhead utilities for less branch interference and underground utilities for less root disturbance.
[2] 
Determining that, in certain cases, the proposed excavation or grade change will have minimal impact on tree health per an arborist.
[3] 
Trimming of branches to clear proposed buildings, parking lots, overhead utilities, site triangles, solar access, etc. An arborist shall determine if the trees will be viable after such trimming.
[4] 
Routine tree maintenance (pruning, dead wood removal, cabling) to remediate an unsafe or unhealthy tree.
(c) 
If the above preservation measures are not appropriate in a given case, then a mature tree, tree mass or woodland may be designated "to be removed" based upon any of the following criteria, but in no case (especially for undesirable trees) shall the live tree count be reduced for their removal:
[1] 
The outermost branches of the tree(s) are within five feet of, or the trunk of the tree is within 20 feet from any proposed building, structure, paving, parking or utilities (overhead or underground).
[2] 
The outermost branches of the tree(s) are within five feet of, or the trunk of the tree is within 20 feet from any proposed changes in grade or drainage such as excavations, mounding, impoundments, or any utility installations or easements.
[3] 
The tree(s) interfere with traffic safety or are located within proposed sight triangles.
[4] 
The tree(s), by its location or apparent health, poses any undue threat to the health, safety and welfare of the community.
[5] 
The tree blocks required solar access.
[6] 
Undesirable or nuisance trees, either individual or species; for example, diseased or insect infested, messy fruiting trees, nonnative, or invasive.
(d) 
Mature trees, tree masses, or woodlands that do not fit the above criteria shall be designated "to remain" or "to be preserved."
B. 
Protection of existing vegetation. Existing vegetation designated "to remain," in accordance with § 260-34D, Tree replacement planting requirements, Subsection D(1), as part of the landscaping of a subdivision or land development shall be identified in the field prior to any clearing and shall be physically protected throughout the construction process. The following additional standards shall apply:
(1) 
A temporary, sturdy physical barrier, such as a snow fence or chain-link fence as determined by the Township, shall be erected a minimum of one foot outside the dripline or a minimum of 20 feet from the tree's trunk, whichever is greater, on all sides of freestanding trees, tree masses, or woodlands prior to major clearing or construction. A detail of said fence shall be provided by the applicant for review by the Township.
(2) 
The barrier shall be placed to prevent disturbance to or compaction of soil inside the barrier and shall remain until construction is complete. No grading shall occur within the protection area, nor shall the placement or storage of construction materials or machinery be permitted in the protection area.
(3) 
The barrier shall be shown on the erosion and sedimentation (E & S) control plan, grading plan and the landscape plan. Reference to the installation of tree protection should be included in the sequence of construction notes to ensure incorporation of tree protection before the earliest stages of site disturbance.
C. 
Credit for preserved trees. Tree plantings required by this chapter are permitted to be satisfied, whenever possible, by utilizing or preserving existing noninvasive, healthy trees. To receive credit, an applicant must demonstrate that the trees intended to be preserved are located in areas of the site suitable to otherwise satisfy the replacement landscape requirement; an applicant must stipulate exactly what replacement landscape requirement is proposed to be credited. Credit for existing trees which are "to remain," or "to be preserved," as determined in § 260-34A(4) above, to offset the replacement tree requirement shall be calculated as follows:
[Amended 12-16-2020 by Ord. No. 2415-20]
Preserved tree
(dbh)
Number of Trees Credited
(3 inches caliper)
18 inches and greater
4 trees*
12 to 17 inches
2 trees*
8 to 11 inches
1 tree*
NOTES:
*
Only one tree shall be credited for each preserved street tree.
D. 
Tree replacement planting requirements.
(1) 
Any subdivision or land development proposal which will result in the destruction of any trees (dead or alive) three inches dbh or greater that would result in the reduction of 10% or more of the total tree dbh in the limit of disturbance (LOD) area shall replace all of the tree dbh removed in excess of 10% as reduced by the appropriate credit for preserved trees in the LOD area. If the LOD area does not reasonably contain enough space for the required replacement trees, they may be planted elsewhere on the subdivision or land development tract. “Existing trees” shall also include all trees which existed on the site two years prior to the submission of the application for subdivision or land development approval. The total tree removal impact of woodland areas designated “to be removed” shall be measured by a forest density survey that calculates the approximate quantity of trees (three inches dbh or greater) per square foot area. Calculated woodland tree removals and individual mature tree removal shall be listed on the plan. Required tree replacements shall be calculated by the following formula:
[Amended 12-16-2020 by Ord. No. 2415-20]
260 figure 4.1 Calculation.tif
(a) 
Each tree three inches dbh or greater that is destroyed shall be replaced with a sufficient number of trees whose total caliper measurement equals the dbh measurement of the tree which is destroyed or removed minus the credit for preserved trees pursuant to § 260-34C, credit for preserved trees. Each individual replacement tree intended to satisfy this requirement shall have a minimum two-and-one-half-inch caliper.
(b) 
Replacement trees shall comply with the landscape design criteria in § 260-63, General landscape design criteria, of this chapter.
(2) 
Replacement trees shall be planted on site to mitigate for existing trees removed. Such replacement trees shall be required to be planted are distinct from and in addition to all other landscaping requirements of this chapter. Proposed replacement tree plantings shall be identified and listed on the plan.
(3) 
If the site does not reasonably contain enough room for the required replacement trees, the Board of Commissioners may allow the developer to locate some or all of the replacement trees on public lands or accept an equivalent fee in lieu of plantings, at their discretion.
(4) 
Calculation and estimation of existing trees shall be performed before any clearing commences and shall be documented on the plan.
(5) 
Calculation and estimation of the existing trees remaining after construction shall be performed and compared with the calculations of the approved plan. Any tree removals additional to those on the approved plan shall be replaced as required by this section prior to the issuing of any occupancy permits.
A. 
Hydric soils. The presence of hydric soils may indicate wetlands. When hydric soils are indicated on the site, a wetlands study should be conducted in accordance with the U.S. Army Corps of Engineers Wetlands Delineation Manual (1987 Manual). In the event no wetland study is undertaken, the location of soils with soils rated as all hydric in the county soil survey on site will be assumed to be wetlands for the purpose of this chapter and shall be noted on the plan as such.
B. 
Wetlands as defined by the U.S. Army Corps of Engineers and the Commonwealth of Pennsylvania in accordance with Section 404 of the Federal Clean Water Act of 1977[1] and the Pennsylvania Clean Streams Act[2] shall be preserved in subdivisions and land developments. Jurisdictional determination of wetlands shall be obtained at an early stage to determine the extent and location in the proposed subdivision and/or land development. Required permits shall be acquired prior to final plan approval.

(1) 
In areas to be graded, the topsoil shall be stripped off and stockpiled on site and only in accordance with the erosion and sediment (E & S) control plan.
(2) 
Following construction, the stockpiled soil shall be screened and redistributed uniformly on site to a minimum depth of eight inches and suitably stabilized by vegetation.
(3) 
Any topsoil in excess of soil needed for the reestablishment of eight inches depth in areas of the site that will not be paved may only be removed from the site provided that written authorization has been obtained from the Township Engineer, and provided that said soil to be removed has been documented and proven to be composed of clean fill. Said soil to be removed shall not be resold, and all attempts shall be made to relocate to a location within the Township, as specified by the Township Engineer.
C. 
Grading. All permanent and temporary cutting, filling, grading, regrading, and/or other forms of earthmoving activities shall be known as "grading" and shall be conducted only in compliance with the standards as described below.
(1) 
All grading shall be set back from property lines at least three feet or a sufficient distance to prevent any adverse effects on adjacent properties.
(2) 
No permanent excavation shall be made with a cut face steeper in slope than 3:1. For steeper slopes, a soils report prepared by a qualified engineer or geologist experienced in performing such studies and registered in the Commonwealth of Pennsylvania shall be prepared to document the soil stability.
(3) 
Wherever grading will increase the volume or velocity of stormwater flow toward a property line, the applicant shall install and maintain drainage facilities sufficient to prevent adverse effects on the adjoining property. The construction and operation of these drainage facilities shall not cause any adverse effects on abutting properties.
(4) 
Within the property proposed for development or along property lines, where grading creates an abrupt dropoff in contrast to a previously existing gradual change or where a wall is being installed, the applicant shall be required to install a fence or other suitable protective barrier.
(5) 
A permit shall be required for grading operations. Permits shall be issued by the Zoning Officer upon recommendation of the Township Engineer for each tract, lot, parcel, or site which comprises a separate operation, unrelated to or not contiguous with nearby grading proposed or performed by the applicant. A permit shall not be required in the following situations, however:
(a) 
For an excavation that does not exceed 10 cubic yards total material removed.
(b) 
For a fill that does not exceed 10 cubic yards of material deposited.
(c) 
For an excavation below finished grade for basements and footings for a single-family detached or two-family dwelling, swimming pool, or underground structure authorized by building permits, excavation for a driveway for a single-family detached or two-family dwelling, or the regrading of such excavated materials into the site from which they were excavated.
A. 
General. Erosion and sediment control must be addressed in the following manner:
(1) 
An erosion and sediment control plan, which meets the requirements of the DEP's Erosion/Sediment Pollution Control Program (Pa. Code Chapter 102, Erosion Control) must be approved by the Montgomery County Conservation District (MCCD) and available on site for all earth-disturbance activities greater than or equal to one acre.
(2) 
All construction activities involving earth disturbance greater than or equal to one acre, or an earth disturbance on any portion, part, or during any stage of a larger common plan of development involving earth disturbance greater than or equal to one acre, must be authorized by a National Pollutant Discharge Elimination System (NPDES) permit.
(3) 
No subdivision or land development plan shall be approved unless:
(a) 
There has been a plan approved by the MCCD and/or Township Engineer that provides for minimizing erosion and sedimentation consistent with this section, and an improvement bond or other acceptable securities are deposited with the Township in the form of an escrow guarantee which will insure installation and completion of the required improvements; or
(b) 
There has been a determination by the MCCD and/or Township Engineer that a plan for minimizing erosion and sedimentation is not necessary.
(4) 
The Board of Commissioners, in its consideration of any preliminary plan of subdivision and land development, shall condition its approval upon the execution of measures designed to prevent accelerated soil erosion and resulting sedimentation, as required by PA DEP. All applicable regulations and permit requirements of PA DEP as stipulated in its Soil Erosion and Sedimentation Pollution Control Manual shall be followed for all earthmoving activities.

The responsibility for maintenance of stormwater management facilities and surface conveyance systems shall lie with the property owner, unless otherwise stipulated by the design plans and/or per agreements of record on file with the Township or the Montgomery County Recorder of Deeds. The easements shall be adequate for such discharge or drainage and for carrying off of such water and for access that may be required for the inspection, maintenance, repair, and reconstruction of the same, including access by vehicles, machinery, and other equipment for such purposes, and which shall be of sufficient width for such passage and work. The Township shall have the right to enter and inspect any such easements and repair any issues that affect the function of the stormwater management facilities, at the expense of the property owner, should the property owner refuse to make such necessary repairs, and/or if the property owner could not be contacted following reasonable efforts to do so.
J. 
Storm drainage directed into an adjacent municipality. When storm drainage will be directed into an adjacent municipality, all provisions for accommodating such storm drainage shall be submitted to the governing body of that municipality for review and approval.
K. 
Discharge of roof runoff. Stormwater runoff from roofs shall not be discharged into the street right-of-way without approval by the Township, upon review by the Township Engineer, nor concentrated onto adjacent properties. It shall be returned to sheet flow or discharged into a structure adequately designed and approved by the Township.
L. 
Properties shall be graded to ensure proper surface drainage away from buildings and to promote the collection of stormwater in conveyance systems per design. Minimum 2% slopes away from structures shall be required.
M. 
Storm sewers.
(1) 
Existing storm sewer accessibility. Where existing storm sewers are reasonably accessible and of adequate capacity, subdivisions and land developments may connect to the existing storm sewers.
(2) 
All storm sewer pipes shall have a minimum diameter of 15 inches.
(3) 
Drainage easements. Storm sewers located within road rights-of-way shall be designed to be parallel with the roadway to the greatest extent possible. When located in undedicated land, they shall be placed within an easement not less than 20 feet wide, as approved by the Township Engineer.
(4) 
Drainage facilities design requirements. All drainage facilities shall be designed to adequately handle surface runoff and carry it to suitable outlets and shall be designed in accordance with the following minimum design standards.
(a) 
All storm drains and drainage facilities such as gutters, catch basins, bridges, inlets, and culverts shall be installed and the land graded for adequate drainage as shown on the grading plan submitted and approved with the final plan. Construction of these facilities shall generally conform with PennDOT Publication 408 (latest version) and PennDOT Publication 72M (latest version). Storm drains and appurtenances shall be required to be constructed by the applicant to take surface water from the bottom of vertical grades to lead water away from springs and to avoid use of cross gutters at street intersections and elsewhere.
(b) 
The existing points of natural drainage discharging onto adjacent property may only be altered in accordance with Chapters 290 and 291 of the Township Code.
(c) 
No stormwater runoff or natural drainage shall be so diverted as to overload existing drainage systems, or create flooding or the need for additional drainage structures on the other private properties or public lands. In cases where increased stormwater flows attributable to an applicant's development will overload existing connected facilities, the applicant shall be responsible for enlarging those facilities to adequately convey, at a minimum, the 100-year storm.
(d) 
Location within township rights-of-way. Storm sewer lines within street rights-of-way shall be placed at locations acceptable to the Township. They shall be protected by a cover of at least 18 inches from surface grade and at least 18 inches from any crossing utility.
(e) 
Location within state rights-of-way. Storm sewer systems that are to be located within state rights-of-way shall be approved by PennDOT by obtaining a highway occupancy permit prior to final plan approval.
(5) 
Collection system design.
(a) 
Storm sewer pipes and/or culverts shall be designed to pass the ten-year design storm without surcharging. However, at the recommendation of the Township Engineer, the storm sewer system shall be designed to convey the twenty-five-year storm where the receiving (downstream) stormwater system has adequate capacity to carry the flow. In addition, storm sewers and/or surface channels of conveyance shall be designed to adequately convey the 100-year design storm volume to a stormwater management BMP, or existing channel or watercourse, without negatively impacting existing or proposed structures.
(b) 
The collection system shall be designed by the rational method of design in accordance with American Society of Civil Engineers Manual No. 37 except where noted, using the formula Q = CiA, unless otherwise approved by the Township Engineer.
(c) 
Curb inlets. Curb inlets shall be located at curb tangents on the uphill side of street intersections, and at intervals along the curbline to control the maximum amount of encroachment of runoff on the pavement. For all storm sewer systems within public roadways, the engineer shall provide bypass calculations to demonstrate that the surface flow width shall not exceed 1/2 the width of any travel lane, based upon the ten-year design storm.
(d) 
The capacity of all inlets shall be based upon a maximum flow to the inlet of 4.0 cfs, calculated based on the design storm event. The maximum flow to inlets located in low points (such as sag vertical curves) shall include the overland flow directed to the inlet as well as bypass runoff from upstream inlets.
(e) 
All storm sewer pipes shall be a minimum of 18 inches in diameter, unless otherwise permitted by the Township Engineer. Roof leaders and underdrains may be less than 18 inches in diameter in accordance with approved designs. All pipes shall be Class III reinforced concrete or HDPE pipe.
(f) 
Open end pipes must be fitted with appropriate endwalls or wing walls. Open culvert endwalls or wing walls for pipes larger than 18 inches in diameter and longer than 60 feet in length shall be fitted with durable protective grates, subject to approval by the Township Engineer.
(g) 
Roof drainage. Stormwater roof drains and pipes shall not discharge water over sidewalks or walkways.
(h) 
All storm structures shall be designed with a minimum two-inch drop in invert between pipe inverts entering and exiting the structures. In addition, where the pipe diameter is the same for pipes entering and exiting structures, a concrete low-flow channel shall be constructed within the bottom of the structure (if not sumped by design) providing a small flow of water through the structure.
(i) 
Manholes. Manholes shall be constructed at all changes in horizontal or vertical alignment and as otherwise required in § 260-79, Utility locations, easements, and rights-of-way.
(6) 
All storm sewer pipes shall be videoed to confirm their structural integrity before dedication to the Township.
N. 
Stormwater management BMPs.
(1)

Any stormwater management facility designed to store runoff and requiring a berm or earthen embankment required or regulated by this chapter shall be designed to provide an emergency spillway to handle flow up to and including the 100-year post-development conditions. The height of the embankment must be set as to provide a minimum 1.0 foot of freeboard above the maximum pool elevation computed when the facility functions for the 100-year post-development inflow rate and volume.
(b) 
Basin berm construction requirements.
[1] 
Site preparation. Areas under the embankment and any structural works shall be cleared, grubbed, and the topsoil stripped to remove trees, vegetation, roots or other objectionable material. In order to facilitate cleanout and restoration, the pool area will be cleared of all brush and excess trees.
[2] 
The minimum top width of detention, retention, wet pond, or any other basin berm that stores stormwater volumes of 10,000 CF or greater at the 100-year water surface elevation shall be 10 feet. For basins with a storage volume less than 10,000 CF, the minimum berm width shall be five feet.
[3] 
Cut of trench. A cutoff trench will be excavated along the center-line dam on earthfill embankments. The minimum depth shall be two feet. The cutoff trench shall extend up both abutments to the riser crest elevation. The minimum bottom width shall be eight feet wide but wide enough to permit operation of compaction equipment. The side slopes shall be no steeper than 1:1. Compaction requirements shall be the same as those for the embankment. The trench shall be kept free from standing water during the backfilling operations.
[4] 
Embankment. The fill material shall be taken from the selected borrow areas. It shall be free of roots, wood vegetation, oversized stones, rocks or other objectionable material. Areas on which fill is to be placed shall be scarified prior to placement of fill. The fill material should contain sufficient moisture so that it can be formed by hand into a ball without crumbling. If water can be squeezed out of the ball, it is too wet for proper compaction. Fill material will be placed in six-inch to eight-inch layers and shall be continuous over the entire length of the fill. Fill material must be compacted to a minimum of 95% of modified proctor density as established by ASTM D-1557. Compaction testing by a certified soils engineer/geologist must be completed as directed by the Township Engineer to verify adequate compaction has been achieved.
(c) 
Emergency spillways discharging over embankment fill shall be constructed of reinforced concrete checker blocks to protect the berm against erosion. Alternate lining materials may be utilized upon approval of the Township Engineer. The lining shall extend to the toe of the fill slope on the outside of the berm and shall extend to an elevation three feet below the spillway crest on the inside of the berm.
(d) 
Stormwater management facility outlet piping shall be Class III reinforced O-ring concrete pipe. Energy dissipating devices shall be placed at all basin inflow points and outfalls. A minimum of one concrete anti-seep collar shall be required. Pre-cast collars shall have a minimum thickness of eight inches; field-poured collars shall have a minimum thickness of 12 inches. Collars may not be installed within two feet of pipe joints. Collars must be designed to project a minimum of two feet around the perimeter of the pipe. Maximum collar spacing is 14 times the design projection around the perimeter.
(e) 
All outlet structures shall be located within the embankment for purposes of maintenance, access, safety and aesthetics. Below-grade structures (standard inlet boxes, manholes, etc.) shall not project above the ground surface. The minimum diameter of any free-flowing orifice shall be three inches. Innovative low-flow or anti-clog devices with free-flowing orifices less than three inches are permitted upon review and approval by the Township Engineer. All inflow headwalls and outlet structures shall be provided with slanted trash racks with a maximum grid opening of four inches by four inches, constructed of aluminum. The trash rack shall be slanted at 45°, to be able to withstand loading of 500 pounds and be hinged at the top for cleaning. Other trash racks may be utilized upon approval of the Township Engineer.
(3) 
Infiltration rates. Infiltration BMPs may only be installed within areas in which the tested infiltration rate falls between 0.1 and 10 inches per hour. Any infiltration system shall be designed to fully drain all water within 72 hours following the peak storage volume of the design storm event. Testing of infiltration rates shall be completed in accordance with Appendix C of the Pennsylvania Stormwater Best Management Practices Manual.
(4) 
Methodology. The Soil Complex Method shall be use for all projects in which the total earth-disturbance area exceeds 1.0 acres. Use of the Rational Formula for analysis of drainage areas shall be permitted only upon approval of the Township Engineer.
(5) 
Retaining walls shall not be specified for use within the 100-year floodplain of any detention/retention facility or any embankment slope or cut slope that is appurtenant to the construction of a detention/retention facility.
(6) 
Whenever a stormwater management facility will be located in an area underlain by limestone, a geological evaluation of the proposed location shall be conducted to determine susceptibility to sinkhole formations. The design of all facilities over limestone formations shall include measures to prevent ground water contamination and, where necessary, sinkhole formations. Soils used for the construction of basins shall have low-erodibility factors ("K" factors). Installation of an impermeable liner shall be required in detention/retention basins.
(7) 
Water quality. In an effort to prevent water quality from negatively affecting stormwater management facilities, stormwater runoff conveyed to all BMPs shall be treated prior to discharge into said BMP, through storm structure inserts, the construction of forebays, or similar devices. The Township Engineer shall approval the use of any and all treatment devices.
(8) 
As-built survey. As-built surveys of the final constructed condition of all stormwater management BMPs designed to address the rate and/or volume of stormwater runoff, shall be provided to the Township by the land developer. For closed or underground BMPs where such surveys are not possible, the land developer shall provide internal video of the constructed conditions to verify compliance with the approved design plans. For any closed BMP system where the final in situ condition will prevent video, the land developer shall ensure that a representative of the Township is present on site during construction to verify compliance with the approved design plans.
O. 
Bridge and culvert design. Any proposed bridge or culvert within or spanning a perennial or intermittent stream shall be designed in accordance with the following principals:
(1) 
All bridges, culverts, and drainage channels shall be designed to convey a flow rate equal to a 100-year, twenty-four-hour storm as defined by the U.S. Department of Agriculture, Natural Resource Conservation Service (previously SCS), Technical Release No. 55. All bridges and culverts shall be designed to convey the 100-year design storm without increasing the extent and depth of the 100-year floodplain.
(2) 
Bridges and culverts shall be designed with an open bottom to maintain natural sediment transport and bed roughness, avoiding acceleration of water velocity above the natural (preexisting) condition. Rock (riprap) lining (native material if possible) shall be installed within a culvert as needed to prevent erosion within the structure. Approximate top of rock lining must be at the level of the existing stream bottom so as to maintain normal water level and unimpeded movement of native animal species.
(3) 
All bridges and/or culverts designed to carry a public or private roadway over an existing watercourse shall be designed with a minimum of 24 inches of freeboard between the 100-year floodplain elevation and the roadway surface (center-line elevation). Where existing bridges and/or culverts are being replaced, every effort shall be made to achieve this design goal with the new construction. In no instance shall the new construction lessen the existing freeboard.
P. 
Green infrastructure and low-impact development practices shall be the first best management practices considered when developing the stormwater management plan for any site. A description shall be provided by the applicant at the time of plan submittal, indicating why said practices were not or could not be implemented, if said practices were not incorporated into the site.

(c) 
If one or more property owners in the association or other type of organization believe that the street is not being properly maintained and cannot succeed in having the association or other type of organization authorize or conduct proper remedies, then that/those property owner(s) may request the Township to authorize an inspection of the street by the Township Engineer. The cost of the inspection shall be paid by those property owners requesting the inspection. If the Township Engineer determines that the street is not being properly maintained, the Township may take corrective actions against the entity maintaining the road.
(8) 
The Board of Commissioners reserves the right to order the private street to be upgraded to meet all of the standards and requirements for a public street, if, at any time it deems the road to be a health or safety hazard for reasons of improper or inadequate maintenance.
(a) 
The full costs of upgrading the street, including engineering, legal and related costs, shall be assessed against the owner of the road. The share of the assessment to be determined by the association's legal access agreements and/or covenants recorded for the private street.
(b) 
Prior to such action by the Board of Commissioners, the landowners with access rights shall be notified, in writing, by certified mail, of the pending action. The landowners will have 30 days from the date of such notice to propose an alternative solution acceptable to the Board of Commissioners.
(9) 
Additional provisions.
(a) 
Any vehicular access way which provides the primary access to more than three lots or housing units, but is not offered for dedication as a public street, shall be considered a private street subject to these requirements.
(b)

(a) 
Number of lots and/or dwelling units in excess of the permitted maximum.
(b) 
Whether or not more lots could be proposed along the private street, in conformance with the applicable zoning, in addition to those proposed in conjunction with the waiver application. For example, one additional unit may be acceptable in itself, but may not be acceptable if a potential would exist for five more lots.
[1] 
The Board of Commissioners may require the applicant to submit a sketch plan and/or information showing the approximate maximum number of lots and/or dwelling units which could be created under the applicable zoning requirements, on all lands serviced by the private street.
[2] 
When conditions are considered favorable for limited additional subdivision under the private street access, the Board of Commissioners may request deed restrictions against further subdivision as a condition of final approval of the subdivision.
(c) 
Ability of a private street to be served by an emergency access as a condition of granting a waiver.
(d)

Whether or not requiring a public street would have an appreciable benefit to the properties and/or the Township in terms of access and traffic circulation.
(f) 
The economic impact of permitting the waiver compared to requiring a public street.
C. 
Nonresidential private streets. Private streets may be permitted by the Board of Commissioners to provide access to various nonresidential developments or lots.
Every street, road, or highway within the Township shall be classified by its function and shall be subject to the requirements for its classification as contained in this article. These classifications are based on the Cheltenham Township Comprehensive Plan, which incorporates standards established by the American Association of State Highway and Transportation Officials (AASHTO), and used by PennDOT. Street classifications are intended to provide appropriate standards for each road, as well as to coordinate street functions and improvements among neighboring municipalities, the region, and the state. Streets shall be designed and built according to Figure 4.8, Road Design Standards, below, according to the following road classification as indicated and defined in the Cheltenham Comprehensive Plan. Subsections A through C below provide general descriptions of each road type; however, it is understood that existing roads in the Township may be atypical of their designated classification, and the Township may consider waivers from standards of Figure 4.8 below when they would be unreasonable or cause undue hardship or where an alternative standard can be demonstrated to provide equal or better adherence to Township planning objectives.
A. 
Arterials. Arterial roads provide a high degree of mobility in order to better serve trips of longer length. They are further classified as follows:
(1) 
Principal arterials. Principal arterials generally provide between two and four lanes of travel depending upon traffic volume and land use density.
(2) 
Minor arterials. Minor arterials interconnect with and augment principal arterials. They are generally spaced at intervals consistent with population density and carry traffic within or between municipalities.
B. 
Major collectors. Major collector roads provide a mix of accessibility and mobility. They typically serve trips of up to four miles in length and channel or distribute traffic to or from a road of a higher classification. Major collectors may accommodate trips within and between neighboring municipalities.
C. 
Local roads. Local roads and streets are all other roads in the Township and have relatively short trip lengths, generally not exceeding one mile. Because property access is their main function, there is little need for mobility and high operating speeds. This function is reflected by use of lower posted speed. Local roads are further classified as follows:
(1) 
Local residential streets. New streets or extensions of existing streets in residential developments function primarily to provide vehicular access and street frontage for each lot. Parking on both sides will be assumed on residential streets unless the development otherwise provides significant off street public parking which is convenient to all the proposed houses.
(2) 
Local nonresidential access streets. These streets shall function primarily to provide vehicular access and street frontage for industrial, office, institutional and commercial lots and land uses.
(3) 
Alleys. Alleys are small service roads which provide a secondary access to lots and buildings where full-width streets provide primary street frontage. They are not permitted to be more than 800 feet in length and shall have a paved cartway of 12 feet with a two-foot clear stabilized grass or gravel shoulder area.

NOTES:
1)
Right-of-way: The right-of-way may be adjusted to accommodate highly urbanized and laterally restricted areas as well as unrestricted areas.
2)
Number of lanes: The number of lanes vary in order to accommodate the traffic volume, turning movements, and land capacity demand for selected level of service. This number does not include right-turn lanes where needed.
3)
Range of lane width: Lane width is based upon minimum and desirable standards as well as other conditions such as being adjacent to a curb or the anticipation of heavy truck traffic.
4)
Shoulder: Shall be provided when required by the Township. Shoulder width is based upon minimum and desirable standards as well as other conditions such as highly urbanized and laterally restricted areas, or the anticipation of heavy truck traffic. Wide shoulders may function as bike lanes.
5)
Parking lane: Parking lane width is based upon minimum and desirable standards as well as other conditions such as lot size, intensity of development, or potential for use as a traffic lane where required by future demand. For principal arterials, parking lanes are only recommended in highly developed areas.
6)
Bicycle lane: Shall be provided when required by the Township. A portion of a roadway that has been designated by striping, signing, or pavement markings for the preferential or exclusive use of bicyclists. Width specifications must be in accordance with FHWA/AASHTO standards. Refer also to § 260-43, Bicycle routes and lanes. Wide shoulders may function as bike lanes.
7)
Verge area: The presence of curbing, grass planter strips and sidewalks will depend upon adjacent land uses and site conditions, according to § 260-40, Sidewalks and verges.
8)
Sidewalks/pathway: Sidewalk width is based upon minimum desirable standards for use along each particular roadway, according to § 260-40, Sidewalks and verges
9)
Cartway Width: For local roads, the total cartway width generally includes travel lanes, parking lanes, and/or shoulders.
Sight distance, horizontal, and vertical curvature, super-elevation, and maximum and minimum street grades shall be determined by the Township Engineer in compliance with the standards contained in A Policy on Geometric Design of Highways and Streets, published by the American Association of State Highway Transportation Officials (AASHTO), most recent edition, or PennDOT standards, whichever is more suitable to site conditions. In addition, the following standards and guidelines shall be complied with:
A. 
Minimum horizontal and vertical curvature for all local access streets shall conform with the standards in Figure 4.9, Street Alignment and Intersection Standards.
B. 
Long radius, gentle curves shall be used rather than shorter radius curves connected by tangents particularly where truck traffic is anticipated.
C. 
Curve-tangent relationships shall follow accepted engineering guidelines for safety and efficiency. For example, minimum radius curves shall not be used at the ends of long tangents.
D. 
Street grades shall be measured along the center line in accordance with the following:
(1) 
Minimum grade for all streets shall be 1%.
(2) 
Maximum grades for arterials and collectors shall be 5% and for residential streets shall be 10%.
(3) 
Curve-grade combinations shall follow accepted engineering guidelines for safety and efficiency. For example, minimum-radius horizontal curves will not be permitted in combination with maximum grades.
(4) 
At all approaches to intersections, street grades shall not exceed 4% for a minimum distance of 50 feet from the intersection of curblines or the edges of cartways.
All street intersections shall be governed by the standards of this section and the appropriate PennDOT or AASHTO standards.
A. 
Number of streets. Not more than two streets shall intersect at the same point.

B. 
Angle of intersections.
(1) 
All intersection approaches shall be designed at 90° angles for a minimum of 50 feet from the edge of the cartway.
(2) 
Where angled intersections are used they should be no less than 65° and designed so that the heavier traffic flow will make the obliquely angled turn rather than the acutely angled turn.
C. 
Improvements to existing intersections. When existing streets intersect at odd angles or have more than four approaches, the applicant shall improve the intersection, to bring it into compliance with this chapter, as required by the Board of Commissioners, based upon advice of the Township Engineer and Planning Commission and other technical advisors or agencies, as appropriate. For state and county highways, improvements shall comply with the requirements of the appropriate agency having jurisdiction over the road.
D. 
Radii of pavement and right-of-way at intersections. Street intersections shall be rounded with tangential arcs at pavement edge (curbline) and right-of-way lines as indicated in Figure 4.9, Street Alignment and Intersection Standards.
E. 
All radii specified herein must be increased if large trucks, fire trucks, or other emergency vehicles would have difficulty with ingress or egress as determined by the Township Fire Marshal.
F. 
Waiver of improvements. The Board of Commissioners may waive the above requirements for improvements to intersections under one or more of the following conditions:
(1) 
When it is demonstrated, through a transportation impact study, that the level of service of an intersection is not reduced due to the proposed improvements or change of use of an applicant's site.
(2) 
When other road improvements are already planned which would correct the problem without changes required of the applicant.
(3) 
When not required by PennDOT where the intersections are under their jurisdiction.
G. 
Single-access street intersections.
(1) 
Single access streets shall be established beginning at a three-way intersection perpendicular to a through street.
(2) 
Four-way intersections may be created using two permanent single access streets intersecting directly opposite one another along a through street, when the through street is a local street.
H. 
All intersections shall provide clear sight distance in compliance with AASHTO and PennDOT standards.
I. 
Street intersection spacing shall be in compliance with the regulations contained in this section, measured from center line to center line.
(1) 
The applicant shall prepare a vehicular access analysis, for all street intersections proposed along arterial and collector streets.
(2) 
The spacings listed in Figure 4.9, Street Alignment and Intersection Standards, shall be considered minimum spacing. Where greater spacing is required in compliance with AASHTO or PennDOT standards, the greater spacing distances shall be applied, as determined by the Township Engineer.
(3) 
Offset intersections. In any case where the center lines of street intersections are, or would be, within 150 feet of each other, they shall be made to coincide by relocating the street within the applicant's land, unless additional problems of sight distance or other safety-related problems would be created. As an alternative, relocation further away from the offset intersection may be done in compliance with the intersection spacing requirements contained herein, when approved by the Board of Commissioners.
Any street which is served by only one intersection with a through street shall be considered a single-access street, regardless of the street's configuration within the proposed subdivision or land development.
A. 
Single-access streets shall be classified as one of the following:
(1) 
Single-access loop streets.
(2) 
Cul-de-sac street.
(3) 
Stub streets.
B. 
Single-access loop streets shall be subject to the requirements for their street classification and the following additional requirements:
(1) 
Shall not serve more than 300 average daily trips.

(2) 
Shall be identified by a standard warning sign stating "No Outlet" when deemed appropriate by the Board of Commissioners to help avoid mistaken turning movements.
(3) 
Shall not be permitted when a through street is possible for the tract under consideration. All cul-de-sac streets must be approved by the Board of Commissioners, with the Township reserving the right to reject any and all cul-de-sac streets proposed. The following shall be used to determine the necessity of the cul-de-sac:
(a) 
Adverse topography such as steep slopes, floodplain, streams, etc.
(b) 
The shape of the tract does not lend itself to a through street.
(c) 
The distance to the nearest street with which to intersect is greater than 300 feet from a proposed cul-de-sac.
(4) 
Shall be a minimum 250 feet but not exceed 800 feet in length. Measurement of the length shall be made from the center line of the abutting through road or point of intersection with another cul-de-sac to the center line of the turnaround, measured along the cul-de-sac street's center line.
(5) 
Shall be provided with a vehicular turnaround at the closed end with a right-of-way radius of at least 60 feet and a paved radius of at least 50 feet. Alternative vehicular turnaround designs are encouraged to improve traffic flow and overall design of the subdivision. If an offset bulb turnaround is used, the bulb should be configured to the left of the approaching road center line. In addition, parking may be prohibited on the cul-de-sac by order of the Fire Marshal.
(6) 
A permanent easement for snow removal shall be required at cul-de-sac bulb. The easement shall have a minimum length along the right-of-way line of 40 feet and a depth of 15 feet. When curbing is required, a curb depression shall also be placed in this easement area. No shrubbery, fence, mailbox, or any other obstruction shall be placed within the easement to hinder the placement of the snow.
(7) 
Shall not extend from a single-access loop street.
(8) 
Existing temporary cul-de sac streets, stub streets, and rights-of-way located on adjacent parcels, whether improved or not, shall be used by the applicant to connect with their proposed roadway system. It shall be the responsibility of the applicant to complete all roadway improvements at their expense within the existing rights-of-way of adjacent parcels.
(9) 
Shall be served by an appropriately located and constructed emergency access way when required by the Board of Commissioners using the following standards:
(a) 
Minimum cartway width shall be 12 feet.
(b) 
Pavement method (whether through grass pavers or other method) shall satisfy the standards of the Township Engineer.
(c)

(c) 
Shall be designed to allow for emergency vehicle access into the cul-de-sac.
(d) 
In the event that right-of-way grading will not permit the retention of existing vegetation in a cul-de-sac, the landscaping proposed for the island shall be of low-maintenance varieties as approved by the Board of Commissioners. The landscaping plan shall specifically describe the maintenance required for any landscaping proposed on the landscape island.
D. 
Stub streets or temporary culs-de-sac.
(1) 
Shall be provided in appropriate locations for vehicular access to abutting undeveloped lands when required by the Board of Commissioners, upon advice of the Township Planning Commission and Engineer.
(a) 
The length shall be designed in accordance with cul-de-sac street standards.
(b) 
The width and other road improvements of temporary stub streets or temporary culs-de-sac shall generally conform with the future functional classification of the roadway once it is fully connected.
(2) 
Shall be provided with a vehicular turnaround that meets cul-de-sac standards.
(3) 
Shall be constructed to the property line in accordance with the standards of this chapter applicable to the classification of streets it will be upon extension.
A. 
The term "driveway" as used here refers to every entrance or exit used by vehicular traffic to or from properties abutting a Township, county, or state road. The term includes proposed private streets, lanes, alleys, courts, and other ways.
B. 
Driveways with the following characteristics will be reviewed in the manner prescribed below:
(1) 
When any residential dwelling driveways will access an existing arterial or collector street.
(2) 
For all nonresidential proposals which require a new driveway or upgrading of an existing driveway.
(3) 
For all proposals where driveways would generate 25 or more vehicular trips per day, based on ITE trip generation standards.
C. 
Following evaluation by the Township, the applicant may submit plans to the state, county, or Township for formal review and, as appropriate, approval and issuance of permits.
D. 
No driveway location, classification, or design shall be considered finally approved by the Township unless highway occupancy or access permits have been granted by the state, county, and/or Township and preliminary plan approval has been granted by the Board of Commissioners for the subdivision and/or land development which the driveway(s) will serve.
E. 
Driveway intersections with streets:
(1) 
Shall provide adequate sight distance in compliance with the standards established by PennDOT.
(2) 
Shall not cause or contribute to:

Hazards to the free movement of normal street traffic, traffic congestion on the street.
(b) 
Interference with the design, maintenance, and/or drainage of the street.
(3) 
Shall be designed and constructed in compliance with Title 67, Chapter 441, of the Pennsylvania Code unless Township standards are more restrictive.
F. 
In order to facilitate safe and efficient access between streets and driveways, the number of driveways permitted to serve individual nonresidential parcels of land shall be kept to the minimum needed to adequately serve the parcel in question. Shared access between adjoining lots should be considered first.
(1) 
Properties with frontages of 100 feet or less may be permitted no more than one driveway intersection with a street. Exceptions may be made when adjacent property owners share parking or when the need is determined in a transportation impact study prepared by a qualified traffic engineer.
(2) 
Not more than two driveway intersections with the same street may be permitted for any parcel of land unless anticipated traffic volumes warrant more than two, and then only when supported by a traffic study prepared by a qualified engineer warrants more than two driveway intersections.
G. 
Driveway intersections serving individual parcels of land may be prohibited by the Board of Commissioners where such intersections would create congestion, interference, and/or hazards to traffic flow and safety by reason of street grades, land forms, vegetation, frequency of driveway intersections, limited sight distances, and/or high-speed traffic flow. In such cases, the Board of Commissioners may permit reasonable alternative forms of vehicular access to the parcel of land by means of:
(1) 
Marginal access streets or driveways.
(2) 
Reverse frontage lotting.
(3) 
Other means which are legally and technically suitable in the opinions of the Township Solicitor and Engineer.
H. 
Where driveway intersections are prohibited by the Board of Commissioners and alternative forms of vehicular access would cause an undue burden upon an applicant, the Board of Commissioners may permit an alternative interim access solution in compliance with the following:
(1) 
It is the safest feasible alternative, acceptable to the Township Engineer and/or PennDOT.
(2) 
Suitable provisions are made for a preferable permanent access solution, consistent with Subsection G, including legal agreements to enable implementation of the permanent solution.
I. 
Distance from street intersections. Driveways shall be located as far from street intersections as is reasonably possible, but is not permitted to be less than 75 feet from the point of intersection between two street center lines.
J. 
Choice of streets. When a lot adjoins streets of different classes, the driveway shall provide access to the street of lesser classification unless this requirement is waived by the Board of Commissioners for reasons of sight distance, incompatibility of traffic, grading, drainage, or other major reasons.
K. 
Sight distance determinations. Determination of sight distances at intersections of new driveways and streets with existing Township roads shall be in accordance with the following provisions:
(1) 
Access driveways shall be located at a point within the property frontage limits which provides at least the minimum safe stopping sight distance (SSSD), as determined by PennDOT standards and Pa. Code standards.
(2) 
The calculated minimum SSSD shall be measured from a point 10 feet back of the pavement edge and 3.5 feet above the road surface.
(3)

(3) 
Where the edge of an existing parking area is located close to a street, driveway, or other parking area and the property is proposed for subdivision and/or land development, a minimum separation of 10 feet shall be provided between these features unless a shared parking or cross access arrangement is proposed. This spacing shall consist of a landscaped area with planting in conformance with § 260-50, herein.
(4) 
Dead-end parking areas shall not be used when the required parking capacity can be accommodated in a layout that permits more convenient vehicular movements. However, extraneous through-traffic flow shall be avoided.
(a) 
Up to 30 parking spaces may also be located in a dead-ended parking area if there is no more desirable alternative feasible and sufficient backup areas are provided for the end spaces.
(b) 
More than 30 parking spaces may be located in a dead-ended parking area only if a turnaround area is provided at the closed end, suitable for passenger car turning. The turnaround area may be circular, T- or Y-shaped, or other configuration acceptable to the Board of Commissioners.
(5) 
Parking spaces designed for the exclusive use by disabled persons shall be installed in all parking lots as close and convenient to building entrances as is reasonable. The specific number and locations of accessible spaces shall be in conformance with the Americans with Disabilities Act (ADA).[1]
[1]
Editor's Note: See 42 U.S.C. § 12101 et seq.
(6)

Where parking spaces abut sidewalks, parked vehicles shall not overhang the sidewalks unless the sidewalk is widened by two feet. Wheel stops are required in order to allow for full pedestrian use of the sidewalks.
(3) 
Parking spaces for physically disabled persons shall be 13 feet wide and equal in depth to the spaces abutting them in accordance with standards developed under the Americans with Disabilities Act (ADA).[2]
[2]
Editor's Note: See 42 U.S.C. § 12101 et seq.
D. 
Shared access. When required by the Board of Commissioners upon recommendation of the Township Planning Commission, applicants shall create agreements for shared vehicular access as the preferred means of reducing the total number of curb cuts for traffic safety and congestion reasons. Nonresidential lots shall provide cross-access easements for parking areas and driveways guaranteeing access to adjacent lots. Interconnections shall be logically placed and easily identifiable to ensure convenient traffic flow.
(1) 
When two or more abutting lots share an access driveway, the driveway shall be designed as the main access to those lots, and one or more existing access driveways shall then be closed.
(2) 
Where development of three or more adjoining parcels consolidates vehicular access into one shared driveway, that driveway may be upgraded into a medium volume driveway according to PennDOT standards.
(3) 
Shared access may be located entirely on one lot or be split among a common lot line.
(4) 
Access easement and maintenance agreements or other suitable legal mechanisms shall be provided, in a form acceptable to the Board of Commissioners in consultation with the Township Solicitor.
(5) 
Liability safeguards for all property owners and lessees served by the shared access shall be guaranteed to the satisfaction of the Board of Commissioners in consultation with the Township Solicitor.
E. 
Drive aisles within sites proposed for nonresidential development. The following requirements apply to all driveways within all sites proposed for nonresidential land development.
(1) 
A smooth transition shall be provided between the driveway section required for access to a public street and the drive aisles required for internal site circulation.
(2) 
Main access driveways (entrance-exit) and service driveways handling large trucks shall be a minimum paved width of 24 feet, with one lane in each direction, unless otherwise required by PennDOT standards governing the volume of traffic anticipated.
(3) 
Wherever feasible, internal circulation driveways shall extend from access drives in locations which permit and encourage entering traffic to turn and enter the parking aisles without first travelling along a building-front drive aisle. This feature is intended to reduce the volume of vehicular traffic along building-front driveways to make it safer for pedestrian traffic.
F. 
Pedestrian circulation and facilities. The following requirements shall apply to all parking areas with 10 or more spaces.
(1) 
Pedestrian circulation. Pedestrian circulation to each building from public sidewalks, the street, and cars parked on site shall take precedence over vehicular circulation. Pedestrian access to each building from public sidewalks and the street shall be physically delineated and provided by sidewalks and defined crosswalks and shall otherwise be exclusive of and separate from vehicular use areas and drive aisles. Defined paths of travel for pedestrians from off-site shall consist of not more than 25% crosswalks or other painted services not grade-separated from vehicular drive aisles or driveways.
(2) 
Crosswalks. Where pedestrian circulation crosses vehicular routes, a crosswalk with a different paving material, ladder-striping, speed tables, or signage shall be provided. Walkways in parking areas shall be barrier-free and a minimum of five feet wide; additional width may be needed in some areas with heavy pedestrian traffic.
(3) 
Entrances. At least one pedestrian route shall be provided and aligned within the parking lot with the main entry of a building to facilitate pedestrian movement. Clear separation or division from vehicular use areas with sidewalks, landscaping, a change in grade, or a change in surface material shall be provided.
Curbing shall be installed along all existing and proposed public and private streets, common driveways, and common parking areas.
A. 
When utilizing an approved stormwater management technique, the Board of Commissioners may waive curbing requirements in full or partially. Grass swales and infiltration trenches along streets are encouraged in appropriate locations in the Township, provided that pedestrian safety and traffic circulation is addressed.
B. 
The Township may waive the installation of sections of curbing when adjoining sections of the road do not have curbing and in the opinion of the engineer it would be better to install the curbing at the same time that curbing is installed along the adjoining sections of the road way. In these cases, payments shall be required to fund the installation of the curbing at a future time when other sections of curbing along the roadway are installed.
C. 
Accessible curb cuts that meet the requirements of the American Disabilities Act[1] shall be installed at all intersections where sidewalks are provided or proposed.

Existing healthy trees, shrubs, or woodlands may be substituted for part or all of the required plant material of this chapter at the sole discretion of the Board of Commissioners, provided such existing vegetation, in its existing location on the site, fulfills the intent of the particular standard for which it is proposed to be substituted. The minimum quantities and/or visual effect of the existing vegetation shall be equal to or exceed that of any required landscape or screening buffer. In order for existing vegetation to qualify, proof must be provided to demonstrate that adequate protection measures, particularly in the plant's root zone, are incorporated into the plan, and comply with the standards of § 260-34B.
E. 
In the event that an applicant requests a waiver from the landscaping requirements of this article on the basis that compliance with such requirements would represent an undue hardship, the grant of any such waiver may be conditioned upon the payment to the Township of a fee in lieu of planting such required landscaping in accordance with the following:
(1) 
The developer shall provide sufficient plans and documentation to establish what landscaping is to be waived and to permit the proper evaluation of the effect of the grant of the proposed waiver and the reasons for such waiver.
(2) 
The fee shall be based upon the value of the required landscaping that is to be waived. The calculation of which value shall be performed by a registered landscaped architect licensed by the Commonwealth of Pennsylvania and shall be based on the costs of materials, installation, relocation and guaranty of the landscaping that is not to be installed.
(3) 
The fee in lieu of the provision of the required landscaping shall be used, unless the developer paying such fee shall agree otherwise, only for the purpose of providing for the planting of trees and other landscaping in parks of the Township or along the streets or highways of the Township.
