[Ord. 260, 9/17/2007]
1. 
The following subdivision and land development principles, standards and requirements will be applied in evaluating plans for proposed subdivisions and land developments.
2. 
The standards and requirements outlined herein shall be considered minimum standards and requirements for the promotion of the public health, safety, and general welfare; however, the Board of Supervisors reserves the right, in any case, to increase the same if conditions so warrant.
3. 
Whenever municipal or other applicable regulations impose more restrictive standards and requirements than those outlined herein, such other regulations shall control.
4. 
Where literal compliance with the standards specified herein is clearly impractical, the Board of Supervisors may modify or adjust the standards to permit reasonable utilization of property while securing substantial conformance with the objectives of this chapter.
5. 
Pursuant to the provisions of § 22-543, substantive changes may be made with regard to selected standards in keeping with § 503(5) of the Pennsylvania Municipalities Planning Code (MPC).
[Ord. 260, 9/17/2007]
1. 
All portions of a tract being subdivided or developed shall be taken up in lots, streets, open spaces, or other proposed uses so that remnants and landlocked areas shall not be created. Reserve strips controlling access to lots, public rights-of-way, public lands or adjacent private lands are prohibited.
2. 
In general, lot lines shall follow Township boundary lines rather than cross them.
3. 
The developer shall conform to all applicable performance standards, including, but not limited to, those contained in the Zoning Ordinance.
4. 
Where the sketch or preliminary plan includes a portion of a tract, which could be further subdivided or developed under the standards of the Zoning Ordinance, the applicant shall demonstrate how the proposed development will affect the remainder of the site, in terms of potential for future use, resource protection, and community circulation.
5. 
The name of a subdivision and the streets located within the subdivision shall be subject to the approval of the Township and, once approved, shall not be changed except with the approval of the Township as a revision to the plans.
6. 
No subdivision or street name within the municipality or zip code areas shall be repeated or be so similar to an existing subdivision or street name so as to cause confusion between the names. Such potential confusion shall be valid cause for the Township to deny approval of a proposed name.
7. 
Streets that are an extension of or obviously in alignment with existing streets shall bear the names of the existing streets.
8. 
No subdivision or street shall be given a name which contains the word "Wrightstown."
9. 
All houses shall receive address numbers. All address numbers shall be assigned by the Township.
[Ord. 260, 9/17/2007]
1. 
Along the existing street on which a subdivision or land development abuts, improvements shall be made to the street as required by the Board of Supervisors. The improvements to the existing street shall be determined by the width of the required cartway and built to the specifications established by Wrightstown Township and pursuant to §§ 22-504 and 507. In wooded areas, this may be modified to preserve trees.
2. 
Proposed streets shall conform in all respects to the municipal plan, or to other street plans or parts thereof as have been officially prepared and adopted by the Township.

Proposed streets shall conform to county and state street and highway plans as have been prepared, adopted and/or filed as prescribed by law, and to the requirements of the Newtown Area Joint Comprehensive Plan and the Newtown Area Joint Municipal Zoning Ordinance.
4. 
Streets shall be related to topography so as to produce reasonable grades, satisfactory drainage, and suitable building sites.
5. 
Internal residential streets should be designed to discourage excessive traffic speeds; however, the arrangement of streets should provide for continuation of existing or platted streets and for proper access to adjoining undeveloped tracts suitable for future subdivision or development. Through streets are preferred over loop roads and culs-de-sac.
6. 
If lots resulting from a subdivision are large enough to permit further subdivision, or if a portion of the tract is not subdivided, adequate street rights-of-way to permit further subdivision shall be provided as necessary, unless the remaining property is restricted from further subdivision in a manner acceptable to the Township.
7. 
Dead-end streets shall be prohibited, except as stubs to permit future street extension into adjoining tracts, or when designed as culs-de-sac.
8. 
Stub streets greater in length than one lot depth shall be provided with a turnaround designed to meet the standards required for culs-de-sac and shall be provided with sufficient rights-of-way to permit further extension of the street onto adjacent property.
9. 
The construction of streets, roads, lanes and driveways, as shown upon final plans and as contained in contract agreements, shall in every respect conform to such requirements as Wrightstown Township may by resolution require for the construction of streets.
10. 
All streets shall be offered for public dedication. Private streets shall not be permitted.
11. 
Specifications. The minimum requirements for improvements shall be those contained in the Pennsylvania Department of Transportation's Specifications (Form 408) as last revised, or those of Wrightstown Township, as the Township may elect.
12. 
Any applicant who encroaches within the legal right-of-way of a state highway is required to obtain a highway occupancy permit from the Pennsylvania Department of Transportation. The Township shall require the applicant to obtain Township approval, and PennDOT approval shall not override the need for Township approval of all street layouts, driveways, and highway occupancy applications.
[Ord. 260, 9/17/2007]
1.

[Ord. 260, 9/17/2007]
1. 
A transportation impact study shall be undertaken for all major subdivisions and land developments as defined in Subsection 2 below. This study will enable the Township to assess the impact of a proposed development on the local transportation system. Its purpose is to ensure that proposed developments do not adversely affect the transportation network and to identify any traffic problems associated with access from the site to the existing transportation network. The study's purpose is also to delineate solutions to potential problems and to present improvements to be incorporated into the proposed development. The study shall assist in the protection of air quality, the conservation of energy and the encouragement of public transportation use.
2. 
Subdivisions and land developments for which a study is required:
A. 
A transportation impact study shall be required for all subdivisions and land developments that meet one or more of the following criteria:
(1) 
Residential. 50 or more dwelling units.

3. 
The Township shall select a qualified traffic engineer and/or transportation planner with previous traffic study experience to prepare the transportation impact study. The Township may utilize applicant's fees, placed in escrow, to fund such studies. Studies submitted by the applicant shall not be considered as a transportation impact study under this chapter and shall not be accepted by the Township as such. The procedures and standards for the traffic impact study, which shall be adhered to by the consultant, are set forth in Subsection 4 below.
4. 
The transportation impact study shall contain, but not be limited to, the following information:
A. 
General Site Description. The site description shall include the size, location, proposed land uses, construction staging and completion date of the proposed land development. If the development is residential, types of dwelling units and number of bedrooms shall also be included. A brief description of other major existing and proposed land developments within the study area shall be provided. The general site description shall also include probable socioeconomic characteristics of potential site users to the extent that they might affect the transportation needs of the site (i.e., number of senior citizens).
B. 
Transportation Facilities Description.
(1) 
The description shall contain a full documentation of the proposed internal and existing external transportation system. This description shall include internal vehicular, bicycle, and pedestrian circulation, all proposed ingress and egress locations, all internal roadway widths and rights-of-way, parking conditions, traffic channelizations, and any traffic signals or other intersection control devices within the site. The site design shall be shown to maximize potential public transportation usage to and from the development, such as providing adequate turning radii at all access points to allow a bus to enter the development. Bus shelter and sign locations shall be designated where appropriate.
(2) 
The report shall describe the entire external roadway system within the study area. Major intersections in the study area shall be identified and sketched. All existing and proposed public transportation services and facilities within a one mile radius of the site shall also be documented. All future highway improvements, including proposed construction and traffic signalization, shall be noted. This information shall be obtained from the 12-Year Highway Capital Program for the Delaware Valley Region, the Comprehensive Plan and from the Pennsylvania Department of Transportation. Any proposed roadway improvements resulting from proposed surrounding developments shall also be recorded.
C. 
Existing Traffic Conditions.
(1) 
Existing traffic conditions shall be measured and documented on all streets and intersections in the study area. Traffic volumes shall be recorded for existing average daily traffic, existing peak hour traffic and for the land development's peak hour traffic. Complete traffic counts at all major intersections in the study area shall be conducted, encompassing the peak highway and development-generated hour(s), and documentation shall be included in the report. A volume/capacity analysis based upon existing volumes shall be performed during the peak hour(s) and the peak development generated hour(s) for all roadways and major intersections in the study area. Levels of service shall be determined for each location.
(2) 
This analysis will determine the adequacy of the existing roadway system to serve the current traffic demand. Roadways and/or intersections experiencing levels of service E or F shall be noted as congestion locations.
D. 
Transportation Impact of the Development. Estimation of vehicular trips to result from the proposal shall be completed for both the street system and the development-generated peak hours. Vehicular trip generation rates to be used for this calculation shall be obtained from Table 22-1.[1] These development-generated traffic volumes shall be provided for the inbound and outbound traffic movements as estimated. The reference source(s) and methodology followed shall be cited. These generated volumes shall be distributed to the study area and assigned to the existing streets and intersections throughout the study area. Documentation of all assumptions used in the distribution and assignment phase shall be provided. Traffic volumes shall be assigned to all access points.
Pedestrian volumes shall also be calculated, if applicable. If school crossings are to be used, pedestrian volumes shall be assigned to each crossing. Any characteristics of the site that will cause unusual trip generation rates and/or traffic flows shall be noted.
[1]
Editor's Note: Table 22-1 is included as an attachment to this chapter.
E. 
Analysis of Transportation Impact.
(1) 
The total future traffic demand based on full occupancy of the proposed subdivision or land development shall be calculated. This demand shall consist of the combination of the existing traffic expanded to the completion year, the development generated traffic, and the traffic generated by other proposed developments in the study area. A volume/capacity analysis shall also be conducted using the total future demand and the future roadway capacity. If staging of the proposed development is anticipated, calculations for each stage of completion shall be made. This analysis shall be performed using the peak highway hour(s) and peak development-generated hour(s) for all streets and major intersections in the study area. Volume/capacity calculations shall be completed for all major intersections.
(2) 
All access points and pedestrian crossings shall be examined as to the feasibility of installing traffic signals. This evaluation shall compare the projected traffic and pedestrian volumes to the warrants for traffic signal installation. Levels of service for all streets and intersections shall be listed.
F. 
Conclusions and Recommended Improvements.
(1) 
All streets and/or intersections showing a level of service below (3) shall be considered deficient, and specific recommendations for the elimination of these problems shall be listed. This listing of recommended improvements shall include, but not be limited to the following elements:
Internal circulation design; site access location and design; external street and intersection design and improvements; traffic signal installation and operation, including signal timing; and transit design improvements.
(2) 
Existing and/or future public transportation service shall also be addressed. A listing of all actions to be undertaken to increase present public transportation usage and improve service, if applicable, shall be included.
(3) 
The listing of recommended improvements for both streets and transit shall include, for each improvement, the party responsible for the improvement, the cost and funding of the improvement and the completion date for the improvement.
(4) 
The Planning Commission shall review the transportation impact study to analyze its adequacy in solving any traffic problems that will occur due to the subdivision or land development and make recommendations to the Board of Supervisors.
(5) 
The Board of Supervisors may decide that certain Improvements contained in the study within the study area are required for preliminary plan approval and may attach these conditions to the preliminary approval.
(6) 
The improvement plans shall not be submitted to the Pennsylvania Department of Transportation until such plans are approved by the Board of Supervisors. This submittal to the Pennsylvania Department of Transportation shall be accompanied by comments of the Planning Commission and the Bucks County Planning Commission.

3. 
Where a subdivision or land development abuts or contains an existing street of inadequate right-of-way width, additional right-of-way width shall be dedicated to conform to the standards set by the Township. Where a subdivision or land development abuts or contains an existing street of inadequate cartway width, the applicant shall be required to widen and/or reconstruct the roadway to meet current Township standards.
4. 
Wherever a tract to be subdivided or developed borders an existing half or partial street, the other part of the street shall be constructed. No new half-streets shall be permitted.
[Ord. 260, 9/17/2007]
1. 
Whenever street lines are deflected in excess of 5°, connection shall be made by horizontal curves. Long radius curves shall be used rather than a series of curves and tangents.
2. 
To ensure adequate sight distance, minimum center-line radii for horizontal curves shall be as follows:
A. 
Principal arterials, minor arterials and major collectors: 500 feet.
B.

8. 
Streets shall be designed, to the extent reasonably possible, so that they do not access another street directly opposite an existing residence. Where no reasonable alternative to access opposite an existing residence is possible, the plans shall provide for buffering which, in the opinion of the Board of Supervisors, adequately protects the existing residence from headlights intruding into the residence.
9. 
Intersections shall be designed to allow for pedestrian crossings in a safe manner by keeping crossing distance to a minimum, by providing crosswalks, which are painted or constructed with contrasting paving materials, to identify crosswalk areas.
[Ord. 260, 9/17/2007]
1. 
All subdivisions and land developments creating 21 or more dwelling units must have a minimum of two access points to existing streets.
2. 
Where a subdivision abuts or contains an existing or proposed arterial or collector street, the Township may require marginal-access streets, reverse-frontage lots, or such other treatment as will provide protection for abutting properties, reduce the number of intersections with the major street and separate local and through-traffic.

[Ord. 260, 9/17/2007]
1. 
Findings. The Board of Supervisors of Wrightstown Township finds that:
A. 
Inadequate management of accelerated stormwater runoff resulting from development throughout a watershed increases flood flows and velocities, contributes to erosion and sedimentation, overtaxes the carrying capacity of existing streams and storm sewers, greatly increases the cost of public facilities to convey and manage stormwater, undermines floodplain management and flood reduction efforts in upstream and downstream communities, reduces groundwater recharge, and threatens public health and safety.
B. 
Inadequate planning and management of stormwater runoff resulting from land development and redevelopment throughout a watershed can also harm surface water resources by changing the natural hydrologic patterns, accelerating stream flows (which increase scour and erosion of stream-beds and stream-banks thereby elevating sedimentation), destroying aquatic habitat and elevating aquatic pollutant concentrations and loadings such as sediments, nutrients, heavy metals and pathogens. Groundwater resources are also impacted through loss of recharge.
C. 
A comprehensive program of stormwater management, including reasonable regulation of development and activities causing accelerated erosion, is fundamental to the public health, safety, welfare, and the protection of the people of the Township and all the people of the commonwealth, their resources, and the environment.
D. 
Stormwater can be an important water resource by providing groundwater recharge for water supplies and base flow of streams, which also protects and maintains surface water quality.
E. 
Through project design, impacts from stormwater runoff can be minimized by using project designs that maintain the natural hydrologic regime, and sustain high water quality, groundwater recharge, stream baseflow, and aquatic ecosystems. The most cost effective and environmentally advantageous way to manage stormwater runoff is through nonstructural project design, minimizing impervious surfaces and sprawl, avoiding sensitive areas (i.e., stream buffers, floodplains, steep slopes), and designing to topography and soils to maintain the natural hydrologic regime.
F. 
Public education on the control of pollution from stormwater is an essential component in successfully addressing stormwater.
G. 
Federal and state regulations require certain municipalities to implement a program of stormwater controls. These municipalities are required to obtain a permit for stormwater discharges from their separate storm sewer systems under the National Pollutant Discharge Elimination System (NPDES).
H. 
Nonstormwater discharges to municipal separate storm sewer systems can contribute to pollution of waters of the commonwealth by the Township.
2. 
Purpose. The purpose of the stormwater management regulations is to promote safety and welfare within Wrightstown Township by minimizing the damages described through provisions designed to:
A. 
Promote alternative project designs and layouts that minimize impacts to surface and ground water.
B. 
Promote nonstructural best management practices.
C. 
Minimize increases in stormwater volume.
D. 
Minimize impervious surfaces.
E. 
Manage accelerated runoff and erosion and sedimentation problems at their source by regulating activities that cause these problems.
F. 
Utilize and preserve the existing natural drainage systems.
G. 
Encourage recharge of groundwater where appropriate and prevent degradation of groundwater quality.
H. 
Address the quality and quantity of stormwater discharges from the development site.
I. 
Maintain existing flows and quality of streams and watercourses in the municipality and the commonwealth.
J. 
Preserve and restore the flood-carrying capacity of streams.
K. 
Provide proper maintenance of all permanent stormwater management facilities that are constructed in the Township.
L. 
Provide performance standards and design criteria for watershed-wide stormwater management and planning.
M. 
Manage stormwater impacts close to the runoff source, requiring a minimum of structures and relying on natural processes.
N. 
Focus on infiltration of stormwater to maintain groundwater recharge, to prevent degradation of surface and groundwater quality, and to otherwise protect water resources.
O. 
Meet legal water quality requirements under state law, including regulations at 25 Pa. Code Chapter 93.4.a requiring protection and maintenance of "existing uses" and maintenance of the level of water quality to support those uses in all streams, and the protection and maintenance of water quality in "special protection" streams.
P. 
Provide a mechanism to identify stormwater controls necessary to meet NPDES permit requirements.
Q. 
Implement an illegal discharge detection and elimination program that addresses nonstormwater discharges into the Township's separate storm sewer system.
R. 
Prevent scour and erosion of stream banks and streambeds.
S. 
Provide review procedures and performance standards for stormwater planning and management.
3. 
The provisions of the Wrightstown Township Stormwater Management Ordinance [Chapter 25] are incorporated into the Wrightstown Township Subdivision and Land Development Ordinance by reference. Where the provisions of this chapter (the Wrightstown Township Subdivision and Land Development Ordinance) conflict with provisions of the Wrightstown Township Stormwater Management Ordinance, the strictest provisions, as determined by the Township, shall apply.

3) 
Any severed roots as a result of excavation shall be trimmed so that their edges are smooth and are cut back to a lateral root if exposed.
(6) 
Trees Damaged During Construction. Tree trunks and exposed roots damaged during construction shall be protected from further damage. Damaged branches shall be pruned according to National Arborist Association standards. All cuts shall be made sufficiently close to the trunk or parent limb without cutting into the branch collar or leaving a protruding stub. All necessary pruning cuts must be made to prevent bark from being torn from the tree and to facilitate rapid healing.
(7) 
Tree Replacement. In the event that trees that are to be protected are removed or damaged by accident or by violation of the tree protection requirements, trees shall be replaced on an inch for inch basis.
G. 
Preservation and Replacement of Existing Trees.
(1) 
Prior to final approval a calculation and estimation of existing trees shall be performed in the presence of the Township Landscape Architect and shall be based on the following procedures:
(a) 
Trees 24 inches in caliper or greater shall be documented individually and noted on the landscape plan and/or existing features plan.
(b) 
The quantity of all trees 10 inches up to 24 inches in caliper shall be counted individually where possible. On sites where an efficient individual count is not possible due to size of the site or quantity of trees, estimation shall be calculated by the following method:
1) 
Three, 100 foot by 100 foot square areas will be staked out in locations acceptable to the owner/developer's representative and the Township Landscape Architect.
2) 
The quantity of trees in each area will be counted and the totals averaged to determine the average number of trees per 10,000 square feet of wooded area.
3) 
This average quantity per area will be used to determine both the quantity of trees being removed and the quantity of trees to remain.
(2) 
In accordance with Newtown Area Joint Municipal Zoning Ordinance § 903.B.5, within the CM and CR-1 Zoning Districts, no more than 15% of woodlands may be developed, disturbed, regraded or cleared of vegetation. No more than 50% of woodlands may be developed, disturbed, regraded or cleared of vegetation in any other Zoning District.
(3) 
Within the CM and CR-1 Zoning Districts, up to 15% of the existing trees of less than 48 inches in caliper may be removed. All trees of 48 inches in caliper or greater shall be preserved.
(4) 
Within all other Zoning Districts, up to 50% of the existing trees of less than 48 inches in caliper may be removed. However, replacement trees are required at the following ratios:
(a) 
Trees of six inches in caliper but less that 12 inches in caliper to be removed shall be replaced at a rate of 40%. Replacement trees of 2 1/2 inches in caliper shall be required to be planted on a tree for tree basis.
(b) 
Trees of 12 inches in caliper but less than 24 inches in caliper to be removed shall be replaced at a rate of 40%. Replacement trees of three inches in caliper shall be required to be planted on a tree for tree basis.

3. 
Dedication of Land Suitable for Park and Recreational Use to the Township.
A. 
The developer or applicant shall dedicate land suitable for park or recreational use to Wrightstown Township, unless one of the alternatives set forth in Subsection 6 is agreed to by the Township and the developer. The land shall not be dedicated until the completion of the necessary and agreed upon improvements is made to the land, and the appropriate facilities are constructed to make the land usable for park and recreation purposes.
B. 
The amount and location of land to be dedicated to the Township shall bear a reasonable relationship to the use of the park and recreational facilities by the present and future residents of Wrightstown Township. At a minimum, the following criteria for dedication of park and recreation areas to the Township shall apply:
(1) 
Residential Subdivision or Land Development. The amount of land to be dedicated for park and recreational areas in residential subdivision or land developments, whether they are single family dwellings or contained within multi-family dwellings, shall be as follows:
(a) 
Single-Family Detached. In the case of subdivisions of single-family detached dwellings, the developer shall dedicate a minimum of 2,500 square feet per dwelling unit for park and recreation use.
(b) 
Single-Family Cluster and Multi-Family Developments. In single-family cluster and multi-family residential developments, the open space and recreation requirements as set forth in the Zoning Ordinance shall be adhered to.
(c) 
Any residential subdivision or land development plan, whether single-family, single-family cluster or multi-family, that contains less than 30 dwelling units may be exempted, at the option of the Board of Supervisors, from the provision of land for parks and recreation purposes but shall be required to pay the fee-in-lieu of the offer of dedication.
(2) 
Nonresidential Subdivision and Land Development. The amount of land to be dedicated for park and recreational areas in a nonresidential subdivision or land development shall be 2,000 square feet per 4,000 square feet of building area, or fraction thereof. The types of park and recreational areas that shall be deemed suitable for nonresidential subdivisions or land developments shall include, but not be limited to:
(a) 
Playing fields (baseball field, soccer field or the like, designed for active recreation, constructed pursuant to the minimum standards of the Township Park and Recreation Board).
(b) 
Tennis court.
(c) 
Tot lots (small playground especially designed for young children).
(d) 
Basketball courts.
(e)

(h) 
Construction of a connecting link or reservation of the right-of-way to the Township's trail system.
(3) 
The land dedicated to the Township for park and recreation purposes need not be a part of the land development or subdivision. It may be located on a separate parcel of land, provided that in the sole discretion of the Board of Supervisors, it is convenient to the subdivision or land development. In addition, the developer, with the approval of the Township may construct park and recreation facilities in a Township park, or the facilities of another developer to satisfy the requirements of this section. Park and recreation facilities which are available to all Township residents as opposed to facilities which are available only to the residents of a particular subdivision or land development are encouraged. Land that is intended to be offered for dedication to the Township shall comply with the criteria established for recreation land in § 22-531, Subsection 4, "Criteria for Locating Recreation Areas."
(4) 
In the event of a conflict between the Joint Municipal Zoning Ordinance and this chapter as to the amount of recreational area which must be dedicated, this chapter shall control.
C. 
When land is being dedicated, notwithstanding the foregoing, the land which is dedicated must meet the minimum lot size for the district within which it is being dedicated.
D. 
Any land dedicated to the Township shall be used only for the purpose of providing park and recreational facilities.
E. 
When land is dedicated, acceptance by the Township shall be by means of a deed of dedication to which a property description of the dedicated recreational areas shall be attached. All changes and agreements should eventually be listed directly on the signed drawing lines. In no event shall the Township be required to accept dedication of park and recreational areas.
F. 
Where a developer dedicates land, the acquisition value of the land plus any improvements being placed on the land for park and recreation purposes must equal or exceed the fee in lieu of dedication as established by resolution of the Board of Supervisors from time to time. If the value of the fee in lieu of dedication is not met or exceeded, the developer must supply the balance of his obligation to supply park and recreation facilities by one or more of the alternatives set forth is Subsection 6 herein.
4. 
Criteria for Locating Recreation Areas. The Planning Commission and Board of Supervisors, in exercising their duties regarding the review of subdivisions and land development plans, shall consider the recommendations of the Park and Recreation Board as well as the following criteria in determining whether to approve the proposed plan (which approval shall include both the use and location of the proposed park and recreation area) in the developer's subdivision or land development plan:
A. 
The site or sites shall be easily and safely accessible and have good ingress and egress for vehicular and pedestrian traffic. No public road shall traverse the site or sites. At least one side of the recreation area shall abut a street within the subdivision or land development for a minimum distance of 50 feet for access of emergency and maintenance vehicles, and for access to a parking lot if one is provided.
B. 
When recreational activities or facilities are adjacent to a street or parking area measures shall be taken to ensure the safety of the users. Measures include, but are not limited to, fencing, raised earthen berm, a hedge of plant material, or physical separation.
C. 
The site or sites shall have suitable topography (maximum of 5% slope), and soil conditions for use and development as a recreation area.
D. 
No more than 25% of an area designated for active recreation may consist of floodplain, wetlands, or slopes in excess of 8% or other natural resources as defined by the Township Zoning Ordinance. Areas of floodplain, wetlands, and steep slopes may not be used for active recreation.
E. 
Active recreation areas may contain only stormwater management facilities that are necessary for the recreation area.
F. 
A site designated for passive recreation may contain lands with natural resources provided that the area can be developed with trails, picnic areas, nature study area, greenways or other activities acceptable to the Township.
G. 
The size and shape of the site or sites shall be suitable for the development as a recreation area. The area shall consist of at least three acres and shall generally have a length to width ratio of three to one. The configuration of the recreation area must be able to accommodate the activities that are proposed. The recreation area shall not include narrow or irregular pieces of land, which are remnants created by the arrangement of the building lots and/or by streets or parking areas. The shape of the recreational area shall be suitable to accommodate those recreation and open space activities appropriate to the location and needs of future residents.
H. 
The recreational activities and/or facilities for which the area is intended shall be specified on the preliminary, final and record plans.
I. 
Recreation areas shall not be traversed by utility easements unless said utilities are placed underground and no part of them or their supportive equipment protrudes above ground level.
J. 
The following shall not be located in recreation areas: sewage treatment or disposal facilities of any type, water storage tanks, well pump houses, and any similar use or other use which is not related to or associated with recreation.
K. 
Active recreation areas shall be located in such a location that the use of the facility will not be a nuisance to the residents of nearby dwelling units. However, the recreation area must be conveniently located and easily accessible to the residents. When active recreation activities are proposed which entail the construction and installation of equipment or playing surfaces, a Type 2 buffer, as described in § 22-525, shall be provided when such activities abut residential uses.
L. 
The recreation area in the proposed development shall be located adjacent to a recreation area in an adjacent development, if one exists. When the adjacent land is vacant, consideration shall be given to locating the recreation land so that in the future it could be combined with the recreation land in the development of that land.
5. 
Review by the Park and Recreation Board.
A. 
At the submission of a preliminary plan, a recreation plan may be submitted to the Township Park and Recreation Board at the discretion of the Township, which may review the plan (both as to use and location) and make recommendations thereon in writing to the Planning Commission and Board of Supervisors. Revised plans shall be resubmitted to the Township Park and Recreation Board for recommendations.
B. 
In certain instances the Board of Supervisors may determine that it is impractical to provide recreation land within the subdivision where the size, shape, location, access, topography, drainage, or other physical conditions of the land, result in there being no area within the proposed subdivision which is practical for dedication to the public or which can be set aside for recreation uses. In that event, the developer shall proceed in accordance with Subsection 6 hereof.
6. 
Alternatives to Dedication of Land.
A. 
Fee in Lieu of Dedication.
(1) 
Where the Board of Supervisors and the developer agree that because of size, shape, location, access, topography or other physical features of the land or any other need of the Township, that it is impractical to dedicate as required by this chapter, the Supervisors shall require a payment of a fee in lieu of dedication of such land from the developer. In the evaluation of a proposed development application, the Planning Commission, Park and Recreation Board, and Board of Supervisors shall take into consideration the importance of providing the opportunity for recreation within the proposed subdivision or land development. The need for recreational areas in the form of tot lots and general-purpose playfields within the development is particularly important for communities with higher density and small lots.
To that end, the applicant is required to provide at least a portion of the required recreation land (2,500 square feet per lot or dwelling unit) on-site as a mini-park for the benefit of the residents. For subdivisions or land developments consisting of two-family, multi-family and/or single-family detached houses on lots of 20,000 square feet or less, a minimum of 750 square feet of the required 2,500 square feet per dwelling unit or lot shall be provided on-site as a recreation area or mini-park.
(2) 
The on-site recreation area or mini-park shall comply with the following standards:
(a) 
A tot-lot shall be provided with play equipment for pre-school age children and an open, grassed playfield.
(b) 
The land shall be usable land for park purposes. A minimum of 75% of the park shall be gently sloping land that is developed as a grassed, open playfield. A maximum of 25% of the mini-park may contain natural resources such as woodland, steep slopes and streams.
(c) 
The development plans shall provide details of the play equipment and play areas that will be provided. The mini-park shall be designed and improved to accommodate informal unstructured recreational use.
(d) 
The area of the recreation land shall be considered to be a part of the park and recreation land that is required by § 22-531, Subsection 3B(1)(a) and (b).
(e) 
The recreation land shall be conveniently located for the residents of the development and shall have frontage on an interior street.
(f) 
The mini-park shall be a destination point of the internal pedestrian bicycle circulation system within the proposed development.
(g) 
In large developments (large in terms of land area and/or number of dwelling units) the mini-park requirement may be provided in two or more locations, provided each is usable and functional as a recreational area.
(h) 
The calculation of the fee in lieu of dedication shall be set forth in detail in a resolution and shall bear a reasonable relationship to the use of the park and recreation facilities by future inhabitants of Wrightstown Township.
(3) 
A fee authorized under this subsection shall, upon its receipt by the Township, be deposited in an interest-bearing account, designated the Wrightstown Township Park and Recreation Fund. Interest earned on such accounts shall be expended only on specific recreation facilities approved by the Board of Supervisors.
B. 
Reservation by Developer for Homeowner's Association.
(1) 
Where the developer and the Board agree, the required lands necessary to be dedicated to the Township may be reserved by the developer for use by the development's homeowner's association. If this is agreed to by the developer and the Township, the lands must be used solely for park or recreation purposes.
(2) 
If the homeowner's association desires to dissolve and offers the land and equipment to the Township, the Park and Recreation Board will review the land condition and maintenance costs and provide budgetary inputs to the Board of Supervisors. The Board of Supervisors will then determine whether they wish the land to be dedicated to the Township or whether the homeowner's association shall be required to continue to own and maintain it.
C. 
Combination. Where the developer and the Township agree, the developer may utilize any combination of the aforementioned techniques to satisfy his park and recreation obligation. However, in no circumstance shall the total value of the acquisition of land, improvements thereon, dedicated land, or reserved land fail to meet or exceed the value of the fee in lieu of dedication established by resolution of the Board of Supervisors from time to time.
[Ord. 260, 9/17/2007]
Major subdivision and land development plans shall be designed to encourage the use of renewable energy systems and to protect solar access for lots and buildings.
[Ord. 260, 9/17/2007]
1. 
Where required by the Board of Supervisors, the developer shall install or cause to be installed, at the developer's expense, street lights in accordance with the final plan approval. Provision shall be made for energizing said lighting prior to the issuance of the first occupancy permit. The developer shall be responsible for all costs involved in lighting the streets until such time that the streets are accepted as public streets by the Township. When the Township accepts the streets, the Township may by resolution assess all costs of the lighting to the property owners along the street.
2. 
The Township may waive the requirement for street lights in order to prevent glare, preserve night darkness, and to maintain rural character.
3. 
All street lights shall be metal or fiberglass pole lights serviced by underground conduit in accordance with a plan to be prepared by the developer's engineer and approved by the Board of Supervisors and by PECO (an Exelon Company).
[Ord. 260, 9/17/2007]
1. 
Monuments shall be placed at each change in direction of boundary, at each angle point and at the beginning and end of curves along all roadways, and at every lot corner.

[Ord. 260, 9/17/2007]
1. 
The Board of Supervisors, recognizing that a situation may arise where additional flexibility is warranted, is authorized to alter the design standards specified in this chapter. The applicant shall present evidence and demonstrate that the variation requested will result in improving the proposed subdivision or land development which may lead to varying the design of specific streets.
A. 
Streets. Standards for streets expressed in this chapter are intended to provide for the safe and intelligent layout of streets which can be easily maintained at minimum cost. There are several aspects which may lead to varying the design of specific streets.
(1) 
Cartway Width. The width of streets has been established to ensure adequate movement of traffic in times of greatest parking loads.
(a) 
Where a street is designed so that all units face on local streets and where on-street parking is not anticipated and no safety hazard will be created, the cartway width may be reduced. This reduction is limited to 28 feet on minor collectors or 20 feet on local streets.
(2) 
Curbs. Curbs are used to channel water to storm sewers, protect pavement edges and keep vehicles off of grassed areas. In certain cases, however, natural drainage should be encouraged. Where topography and soils permit, roadside swales, set back a minimum of 10 feet from the edge of the cartway, may be substituted for curbs, provided that the alternate design:
(a) 
Ensures adequate means for the protection of pavement edges.
(b) 
Handles stormwater in a manner to ensure against erosion or other conditions detrimental to the public health, safety or welfare.
(c) 
Has the approval of the Township Engineer.
(3) 
Right-of-Way Widths. Right-of-way widths are intended to provide enough land for streets, sidewalks, driveway aprons, street trees, cut or fill slopes, and utilities. They are intended to provide an additional buffer between dwelling units and streets. Where sidewalks are not run along streets, cartway widths are reduced (see paragraph .A.1 above), utilities are located outside of the right-of-way, or dwellings will not front on the streets, a reduction in the widths of rights-of-way may be permitted. In no instance shall a right-of-way width be reduced to less than 33 feet.
B. 
Sidewalks. Sidewalks are intended to provide as separate means of movement for pedestrians. Modern design practice encourages the location of sidewalks away from streets. In order for the Board of Supervisors to waive the requirement for sidewalks to be within a street right-of-way, all of the following provisions for relocated sidewalks shall be met:
(1) 
The walks shall be all-weather and easily cleared of snow.
(2) 
They shall be convenient for the most frequent trips, such as children walking to school bus stops.
(3) 
The walks shall remain as private property, and the responsibility for their maintenance shall be clearly established, such as by a homeowner's association.
