A. 
The following subdivision and land development principles, standards and requirements will be applied by the Borough in evaluating and approving plans for proposed subdivisions and land developments.
B. 
The standards and requirements outlined herein shall be considered minimum standards and requirements for the promotion of the public health, safety, and general welfare.
C. 
Whenever municipal or other applicable regulations impose more restrictive standards and requirements than those outlined herein, such other regulations shall control.
A. 
All portions of a tract being subdivided shall be taken up in lots, streets, public lands, open space or other proposed uses so that remnants and landlocked areas shall not be created. No lot shall be subdivided under the provisions of this chapter if any of the resulting lots would not meet the provisions of the Tullytown Borough Zoning Ordinance.
B. 
Lot lines shall follow Borough boundary lines rather than cross them.
C. 
Whenever possible, developers shall preserve trees, groves, waterways, scenic points, historic spots and other community assets and landmarks.
D. 
Subdivisions and land developments shall be laid out so as to avoid the necessity for excessive cut or fill. Excessive cut or fill shall be defined as site improvements requiring greater than four feet of excavation or backfill. Site disturbance, grading, removal of vegetation shall be the absolute minimum necessary to meet ordinance requirements. Natural drainage patterns and vegetation shall be preserved to maximize infiltration of water.
E. 
Land subject to flooding (in accordance with the Federal Emergency Management Agency (FEMA), the Flood Hazard Boundary Map (FHBM), and the Bucks County, Pennsylvania Soil Survey) or other hazards to life, health or property, and land deemed to be topographically unsuitable, shall not be platted as building sites or for such other uses that may increase the danger to health, life, property, or aggravate erosion or flood hazard until all such hazards have been eliminated, or unless adequate safeguards against such hazards are provided by the subdivision and land development plans. Such land within the subdivision or land development shall be set aside on the plan for uses that shall not be endangered by periodic or occasional inundation.
F. 
Proposed subdivisions and land developments may be coordinated with existing nearby neighborhoods both within and outside of the Borough so that the community, as a whole, may develop harmoniously. Joint reviews with neighboring municipalities may be conducted at Council's discretion.
G. 
Unless a permit is obtained from the Pennsylvania Department of Environmental Protection (PaDEP), discarded building material shall be disposed of in a manner consistent with the Pennsylvania Solid Waste Management Act of 1980, 35 Pa.C.S.A. § 6018.101 et seq. Such material shall not be disposed of on site but shall be taken to a licensed disposal facility.
A. 
Along the existing street on which a subdivision or land development abuts, improvements shall be made to the street as required by the Council. The improvements to the existing street shall be determined by the width of the required cartway and built to the specifications established by Tullytown Borough.
B. 
The arrangement, character, extent, width, grade and location of proposed streets shall be considered in their relation to existing and planned streets, topographical conditions, public convenience and safety, and in their appropriate relation to the proposed uses of the land to be served by such streets.
C. 
The Borough Council may officially prepare and adopt street plans for certain neighborhoods and impose the adopted plan on future subdivision proposals.
D. 
Proposed streets shall conform to such county and state street and highway plans as have been prepared, adopted and/or filed as prescribed by law.
E. 
Streets shall be related to topography so as to produce reasonable grades, satisfactory drainage, and suitable building sites.
F. 
Residential streets shall be so laid out that their use by through traffic will be discouraged.
G. 
Where a subdivision or land development abuts or contains an existing or proposed arterial or collector street, Council, with advice from the Planning Commission, may require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, extra deep lots with rear service alleys or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
H. 
Where a subdivision or land development borders on or contains a railroad right-of-way or limited access highway, Council, with advice from the Planning Commission, may require a street approximately parallel to and on each side of the right-of-way for such purposes as parks in residential districts and commercial or industrial purposes in appropriate districts. Such distances shall be determined with due regard for the requirements of intersections, approach grade and future grade separation.
I. 
Streets that are extensions of or obviously in alignment with existing streets shall bear the names of the existing streets. Street names shall not be repeated and all street names shall be subject to the approval of the Borough Council.
J. 
If lots resulting from the original development are large enough for resubdivision, or if a portion of the tract is not subdivided, adequate street rights-of-way to permit further subdivision or development shall be provided as determined necessary by Council.
K. 
Where the subdivision or land development adjoins undeveloped acreage, Council may require stub streets to the boundary lines of the development with temporary easements for turnarounds. Stub streets greater in length than one lot depth shall be provided with a temporary turnaround to the standards required for culs-de-sac. It shall be the developers responsibility to remove the temporary paving.
L. 
Private streets are to be discouraged. They will be approved only if they are designed and constructed to meet all requirements of public street standards and the recorded plan, and other recorded documents shall disclose the parties or persons responsible for the cleaning, maintaining, improving and repairing of private streets.
M. 
Dead-end streets shall be prohibited, except as stubs to permit future street extension into adjoining tracts, or when designed as culs-de-sac.
N. 
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 Borough shall require the applicant to obtain Borough approval, and PennDOT approval shall not override the need for Borough approval of all street layouts, driveways, and highway occupancy applications.
A. 
Culs-de-sac, where permanently designed as such, shall not exceed 500 feet in length or furnish access to more than 20 dwelling units. Each cul-de-sac street shall have a minimum length of 250 feet, measured in accordance with PennDOT's standards for liquid fuel tax reimbursement.
B. 
Cul-de-sac streets shall be designed in accordance with the standards for secondary streets listed in § 153-604.
C. 
The right-of-way radius at the turnaround shall not be less than 60 feet and shall be paved for a turning radius of not less than 40 feet.
D. 
Drainage, where feasible, should be toward the open end.
E. 
A planted island shall be required at the Borough's discretion in the center of the cul-de-sac. If provided, the planted island shall be 20 feet in diameter. Ownership and maintenance of the planted island shall be designated on the approved final plan of the subdivision or land development.
F. 
All public cul-de-sac streets shall have a snow storage easement to facilitate snow removal.

C. 
Parking area landscaping.
(1) 
All parking areas shall have at least two trees for every 10 parking spaces, which shall be in addition to any other requirements for buffering or landscaping. Trees shall be planted in such a manner as to afford maximum protection from the sun for parked vehicles. However, no plantings that obscure vision or have the potential to obscure vision shall be permitted in interior parking areas within parking lots.
(2) 
In parking lots designed to accommodate rows of parked vehicles, a ten-foot-wide raised landscaped parking island shall be provided along every other row of parking spaces. Planted islands shall contain a mix of deciduous trees and evergreen and deciduous shrubs. A plan for the perpetual care of the landscaped area shall be provided to the Borough.
(3) 
No more than 20 parking spaces or 200 feet shall be permitted in a continuous row without being interrupted by a ten-foot-wide raised separation to provide areas for landscaping.
(4) 
Plantings shall be able to survive soot and gas fumes. Trees which have low-growing branches, gum or moisture which may drop on vehicles; blossoms, thorns, seeds, or pods which may clog drainage facilities shall not be permitted.
D. 
Planting specifications and installation.
(1) 
Street trees and other required plants shall be of nursery stock grown under climatic conditions comparable to those of Tullytown Borough. They shall be of symmetrical growth, free of insects, pests, and disease, and be suitable for street use and durable under the maintenance contemplated.

A. 
General requirements.
(1) 
A tree protection zone (TPZ) must be constructed around any tree which is to be retained. Where there is a group of trees or woodlands, the tree protection zone shall be the aggregate of the protection zones for the individual trees.
(2) 
Grade changes and excavations shall not encroach upon the tree protection zone (TPZ).
(3) 
No toxic materials shall be stored within 100 feet of a TPZ, including petroleum-based and/or -derived products.
(4) 
The area within the TPZ shall not be built upon, nor shall any materials be stored there either temporarily or permanently. Vehicles and equipment shall not be parked in the TPZ.
(5) 
When tree stumps are located within 10 feet of the TPZ, the stumps shall be removed by means of a stump grinder to minimize the effect on surrounding root systems.
(6) 
Tree roots which must be severed shall be cut by a backhoe or similar equipment aligned radially to the tree. This method reduces the lateral movement of the roots during excavation, which if done by other methods could damage the intertwined roots of adjacent trees.
(7) 
Within four hours of any severance of roots, all tree roots that have been exposed and/or damaged shall be trimmed cleanly and covered temporarily with moist peat moss, moist burlap or other moist biodegradable material to keep them from drying out until permanent cover can be installed.
(8) 
Sediment, retention and detention basins shall not discharge into nor be located within the TPZ.
B. 
The tree protection zone (TPZ). Prior to construction, the tree protection zone shall be delineated by the following methods:
(1) 
The TPZ that is delineated on the site prior to construction shall conform to the approved development plans.
(2) 
All trees scheduled to remain shall be marked; where groups of trees exist, only the trees on the edge need to be marked.
(3) 
A forty-eight-inch-high wooden snow fence, mounted on steel posts, located eight feet on center, shall be placed along the boundary of the TPZ.
(4) 
In addition to the TPZ, trees may be left standing as protection between the trunks of the trees to be retained and the limits of grading. When additional trees are used as protection, the TPZ on the approved plan shall be marked in the field so that the additional buffer area is delineated. When this method of protection is used, these additional trees shall be removed at the time of completion of the project.
(5) 
When the wooden snow fence has been installed, it shall be inspected and approved by the municipal arborist prior to commencing clearing and further construction; the fencing along the TPZ shall be maintained until all work/construction has been completed; any damages to the protective fencing shall be replaced and repaired before further construction shall begin.
(6) 
Trees being removed shall not be felled, pushed or pulled into a TPZ or into trees that are to be retained.
(7) 
Any trees within the TPZ that die during the construction of a land development or during the eighteen-month maintenance period, where applicable, shall be removed by the developer and replaced with an approved canopy tree in a location designated by Council.
C. 
Retaining walls.
(1) 
When the original grade cannot be retained at the TPZ line, a retaining wall shall be constructed outside of the TPZ.
(2) 
The retaining wall shall be designed to comply with the municipal standards for retaining walls.
(3) 
In addition, the following methods shall be used to ensure the survival of the tree:
(a) 
The top of the wall shall be four inches above the finished grade line.
(b) 
The wall shall be constructed of large stones, brick, building tile, concrete blocks, or treated wood beams not less than six inches by six inches; a means for drainage through the wall shall be provided so water will not accumulate on either side of the wall; weep holes shall be required within any wall.
153 Article 6 tree.tif
(c) 
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.
(d) 
A layer of clean stone (sized 3/4 to one inch) shall be placed one foot out from the wall to aid in drainage.
D. 
Pruning methods. All final cuts shall be made sufficiently close to the trunk or parent limb but without cutting into the branch collar or leaving a protruding stub, according to the National Arborist Association standards. All necessary pruning cuts must be made to prevent bark from being torn from the tree and to facilitate rapid healing. Flush cuts are unacceptable.
E. 
Fertilization methods.
(1) 
All trees which have experienced any disturbance or have had damages to the roots or branches shall be fertilized.
(2) 
Trees shall be fertilized in early fall (September—October) or mid-spring (April—May). Fall applications are preferred.
(3) 
Fertilizer shall be broadcast over the soil surface in an area twice the size of the TPZ at the rates given below in Subsection E(5). A minimum of 1,000 square feet per tree shall receive fertilization.
(4) 
Fertilizer grade shall have approximately three parts nitrogen to one part phosphorus and potassium (3-1-1 ratio).
(5) 
Fertilizer shall be applied at a rate equivalent to one pound nitrogen per 1,000 square feet.
A. 
General. All residential subdivision or land development submissions to the Borough shall be required to provide for the public dedication or reservation of land suitable for park and/or recreation use in accordance with the provisions of this chapter.
(1) 
A minimum of 1,500 square feet of suitable recreation land shall be provided per dwelling unit within all residential subdivisions or land developments, unless the developer agrees to a fee in lieu thereof as outlined in § 153-617C listed below.
(2) 
Recreation areas shall be readily accessible to all development residents, or, in the case of recreation areas dedicated to the Borough, shall be easily and safely accessible to the general public. At least one side of the recreation area shall abut a street for a minimum distance of 50 feet for access of emergency and maintenance vehicles.
(3) 
The configuration of the recreation area must be suitable for active or passive recreation by reason of its size, shape, location and topography. The required minimum area shall not include narrow or irregular pieces of land which are remnants from plotting and/or street and parking areas.
(4) 
The site or sites shall have suitable topography and soil conditions for use and development as a recreation area.
(5) 
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.
B. 
Dedication to the Borough.
(1) 
In a case where the developer does not wish to retain the required recreation area or open space, or it is not accepted by an approved conservation organization, such area may be dedicated to the Borough for public use.
(2) 
Before approving any site to be dedicated to the Borough for recreational areas and open space, Council shall seek the advice of the Borough Park and Recreation Board and the Planning Commission.
(3) 
Such areas dedicated to the Borough for public use shall be suitable for recreational purposes or open space by reasons of size, shape, location, topography, and access.
(4) 
If Council deems it to be in the public interest to accept in dedication land for recreational purposes and open space purposes, such acceptance shall be by adoption of a resolution or ordinance of Council and acceptance of a deed of dedication from the developer or applicant, and in addition thereto the developer shall contribute to the Borough a sum of money to be determined by resolution of Council. Said sum shall be deposited in a special maintenance account by the Borough and shall be used only for the purpose of developing and maintaining dedicated land within the Borough. In addition, where Council has deemed it to be in the public interest to accept in dedication land for recreational purposes and open space purposes, the developer shall contribute to the Borough a sum of money to be determined by resolution of Council. Said sum shall be deposited in a special capital reserve account by the Borough and shall be used only for the purpose of acquisition of land or capital improvements for recreational purposes.
(5) 
If Council deems it to be in the public interest to accept in dedication land for drainage detention or retention purposes, such acceptance shall be by adoption of a resolution or ordinance of Council and acceptance of a deed of dedication from the developer, and in addition thereto, the developer shall contribute to the Borough a sum of money to be determined by resolution of Council. Said sum shall be deposited in a special maintenance account by the Borough and shall be used only for the purpose of maintaining dedicated land within the Borough.
C. 
Fee in lieu of dedication.
(1) 
Where Council agrees that because of the size, shape, location, access, topography or other physical features of the land or any other need of the Borough, that it is impractical to dedicate land to the Borough or set aside a recreation area or open space area as required by this chapter, Council shall require a payment of a fee in lieu of dedication of such land from the developer or applicant which shall be payable to the Borough prior to approval of each final section of the overall plan by Council. Such fee shall be calculated by multiplying the number of dwelling units in each section by the fee per dwelling unit.
(2) 
The amount of the fee shall be determined by resolution of Council.
(3) 
All moneys paid to the Borough pursuant to recreational land requirements shall be kept in an interest-bearing capital reserve fund and shall be accounted separately from other Borough funds. Moneys in such fund shall be used only for the acquisition of land, development of and capital improvements to recreational facilities, landscaping of recreational land, engineering, legal, planning, architecture, landscape architecture and the payment of debt directly resulting from such expenditures. Such funds shall not be used for maintenance, routine repairs, operating expenses, or recreational programs.
A. 
General.

(3) 
Measures used to control erosion and reduce sedimentation shall, at a minimum, meet the standards and specifications of the Pennsylvania Department of Environmental Protection Erosion and Sediment Pollution Control Program Manual, latest edition, as administered by the Bucks County Conservation District. The Borough Engineer shall ensure compliance with the appropriate specifications, copies of which are available from the District.
B. 
Performance principles. In those areas where grading is permitted, the mandate by the Borough is to keep grading and site disturbance to a minimum so that natural drainage patterns and natural vegetation are preserved. The following measures are effective in minimizing erosion and sedimentation and shall be included where applicable in the control plan:
(1) 
Stripping of vegetation, regrading, or other development shall be minimized and shall be done in a way that will minimize erosion.
(2) 
Development plans shall preserve pertinent natural features, keep cut and fill operations to a minimum, and ensure conformity with topography so as to create the least erosion potential and adequately handle the volume and velocity of surface water runoff.
(3) 
Whenever feasible, natural vegetation shall be retained, protected and supplemented. The natural vegetation which is to be preserved shall be protected during construction from changes in grade, damage by construction equipment and/or storage of materials or fill. (See § 153-616.)
(4) 
The disturbed area and the duration of exposure shall be kept to a practical minimum and shall be stabilized immediately.
(5) 
All disturbed areas which are steeply sloped (25% or steeper) or where there is a severe potential for erosion shall be immediately seeded, mulched or otherwise protected from accelerated erosion and sedimentation.
(6) 
The permanent (final) vegetation and mechanical erosion control and drainage shall be installed as soon as practical in the development. For an earth disturbance activity or any stage or phase of activity to be considered permanently stabilized, the disturbed areas shall be covered with one of the following:
(a) 
A minimum uniform 70% perennial vegetative cover, with a density capable of resisting accelerated erosion and sedimentation.
(b) 
An acceptable best management practice (BMP) which permanently minimizes accelerated erosion and sedimentation.
(7) 
Provisions shall be made to effectively accommodate the increased runoff caused by changed soil and surface conditions during and after development.
(8) 
Sediment in the runoff water shall be trapped until the disturbed area is stabilized by the use of debris basins, sediment basins, silt traps, or similar measures.
C. 
Site grading for erosion control. In order to provide more suitable sites for building and other uses, improve surface drainage, and control erosion, the following requirements shall be met:
(1) 
All grading shall provide proper drainage away from buildings and dispose of it without uncontrolled ponding, except where ponding is part of the stormwater management plan.
(2) 
Concentration of surface water runoff shall be permitted only in swales, watercourses, retention or detention basins. Subject to the approval of the Borough Engineer, swales shall be sodded, utilizing the appropriate stabilization fabric, or other similar measures to insure establishment of ground cover.
(3) 
Grading shall not be performed in such a way so as to divert water onto the property of another landowner.
(4) 
During grading operations, necessary measures for dust control must be exercised. Windblown erosion shall not be permitted.
(5) 
Grading equipment will not be allowed to cross streams. Provisions shall be made for the installation of temporary culverts or bridges.
(6) 
Tire cleaning areas shall be provided at each point of access to the development site.
(7)

D. 
Excavations and fills.
(1) 
No excavation shall be made with a cut face steeper than 3:1 (horizontal to vertical), except under one or more of the following conditions:
(a) 
The excavation is located so that a line having a slope of 3:1 and passing through any portion of the cut face will be entirely inside the property lines of the property on which the excavation was made and shall not result in property damage or be a hazard to adjoining property, streets, alleys, or buildings.
(b) 
The material in which the excavation is made is sufficiently stable to sustain a slope of steeper than three horizontal to one vertical. A written statement to that effect from an engineer, licensed by the Commonwealth of Pennsylvania and experienced in erosion control, shall be submitted to the Borough Engineer for approval. The statement shall affirm that the site has been inspected and that the deviation from the slope will not result in injury to persons or damage to property.
(c) 
A concrete, masonry, or other approved retaining wall constructed in accordance with approved standards is provided to support the face of the excavation.
(2) 
No fill shall be made which creates any exposed surface steeper in slope than 1 1/2 horizontal to one vertical, except when the plan for subdivision or land development is accompanied by a written statement prepared by a civil engineer, architect, or landscape architect licensed by the commonwealth, certifying that he has inspected the site and that the proposed deviation from the slope specified above will not endanger any property or result in property damage. The plan and statement must be submitted to and approved by the Borough Engineer.
(3) 
Fill shall be placed and compacted so as to minimize sliding or erosion of soil.
(4) 
Adequate provisions shall be made to prevent surface water from damaging the cut face of excavations and the sloping surfaces of fills.
(5) 
Fill shall not encroach on natural watercourses or constructed channels.
(6) 
Fill placed adjacent to natural watercourses or constructed channels shall have suitable protection against erosion during periods of flooding. Compliance with § 185-71B(8) of the Tullytown Borough Zoning Ordinance, which contains regulations regarding placement of fill in the floodplain, shall be demonstrated.
(7) 
Cut and fill operations shall remain entirely inside the property lines of the property on which the excavation is proposed and shall not endanger adjoining property or streets.
(8)

E. 
Responsibility.
(1) 
Whenever sedimentation is caused by stripping of vegetation, grading or other development, it shall be the responsibility of the person, corporation or other entity causing such sedimentation to remove it from all affected surfaces, drainage systems and watercourses on and off site and to repair any damage at his/her expense as quickly as possible.
(2) 
Maintenance of all drainage facilities and watercourses, both existing and proposed, within any proposed subdivision or land development shall be the responsibility of the developer until such time as one of the following is accomplished:
(a) 
An easement for these facilities is offered for dedication by the developer and is accepted by the municipality; it shall then be the responsibility of the municipality.
(b) 
An easement acceptable to the municipality is established, but not dedicated to the municipality. In the case of a subdivision, the maintenance shall then be the responsibility of the individual lot owners over whose property the easement passes. For land developments, the maintenance shall then be the responsibility of the owner.
(c) 
A homeowners' association or other approved legal entity, approved by the municipality, assumes responsibility for the maintenance of the development, including the maintenance of the watercourse and/or drainage facilities.
(3) 
It is the responsibility of any person, corporation, or other entity doing any work on or across a stream, watercourse or swale, or upon the floodplain or right-of-way during the period of the work, to return it to its original or equal condition after such activity is completed. This shall require revegetation of stream banks.
(4) 
No person, corporation, or other entity shall block, impede the flow of, alter, construct any structure, or deposit any material or thing, or perform any work that will affect normal or flood flow in any communal stream or watercourse without having obtained prior approval from the Borough and/or the Pennsylvania Department of Environmental Protection, whichever is applicable.
(5) 
Each person, corporation, or other entity which makes any surface changes shall be required to:
(a) 
Collect on-site surface runoff and control it in a manner acceptable to the municipality upon advice from the Borough Engineer.
(b) 
Handle existing off-site runoff through his/her development by designing it to adequately handle one-hundred-year, twenty-four-hour storm runoff from a fully developed area upstream.
(c) 
Pay a proportionate share of the total cost of off-site improvements to the common natural watercourse, based on a fully developed drainage area.
(d) 
Provide and install at their expense, in accordance with municipal requirements, all drainage and erosion control improvements (temporary and permanent) as required by the erosion and sediment control plan.
F. 
Compliance with regulations and procedures.
(1) 
The governing body in its consideration of all preliminary plans of subdivision or land development shall condition its approval upon the execution of erosion and sediment control measures as contained in this section.
(2) 
The installation and design of the required erosion and sediment control measures, as listed in the Erosion and Sedimentation Control Plan Development Checklists Standard Worksheets Details and Notes, shall be in accordance with standards and specifications found in the Erosion and Sediment Pollution Control Handbook of the Pennsylvania Department of Environmental Protection available through the Bucks County Conservation District.
(3) 
Stream channel construction should be consistent with the requirements of the Dam Safety and Encroachments Act, Chapter 105.[1]
[1]
Editor's Note: See 32 P.S. § 693.1 et seq.
(4) 
Final plans for minimizing erosion and sedimentation as approved will be incorporated into the agreement and bond requirements as required by the municipality.
(5) 
The approval of plans and specifications for the control of erosion and sedimentation shall be concurrent with the approval of the final plans of subdivision or land development, and become a part thereof.
(6) 
At the time a building permit is applied for, a review shall be conducted by the Borough Engineer to ensure conformance with the plan as approved. During the construction, further consultative technical assistance will be furnished, if necessary by the Borough Engineer and the Bucks County Conservation District. During this development phase, the Borough Engineer shall inspect the development site and enforce compliance with the approved erosion and sediment control plans.
A. 
Additional width of streets adjacent to areas proposed for nonresidential use may be required by the Borough to ensure the free flow of through traffic from vehicles entering or leaving parking areas.

Purpose. A transportation impact study shall be required for all major subdivisions and land developments or zoning changes, special exceptions, or conditional uses as defined below in Subsection C. This study will enable Tullytown Borough to assess the impact of a proposed development, zoning change, special exception, or conditional use on the transportation system, both highways and public transportation in Tullytown Borough. Its purpose is to ensure that proposed developments or zoning changes do not adversely affect the transportation network and to identify any traffic problems that are created in the existing highway network as a result of the development, zoning change, special exception, or conditional use. The study's purpose is also to delineate solutions to potential problems and to present improvements to be incorporated into the proposed development or to the highway and/or public transportation systems within the study area as designated in Subsection D. The study shall assist in the protection of air quality, the conservation of energy and the encouragement of public transportation use.
B. 
Conduct of the transportation impact study. The transportation impact study shall be prepared by a qualified traffic engineer and/or transportation planner with previous traffic study experience. The procedures and standards for the traffic impact study are set forth in § 153-628E of this chapter.
C. 
Applicability.
(1) 
A transportation impact study shall be submitted for all change of zoning requests, special exceptions, conditional uses, and as part of the preliminary plan application for all subdivision and land development proposals that have the potential of generating 350 or more trips per day. The number of trips per day are determined through the use of Institute of Transportation Engineers (ITE), Trip Generation, (7th edition or as amended). The proposed use or development shall be identified using the ITE land use code that best describes the use of the proposed development. Where doubt exists, the applicant shall seek guidance from the Borough Engineer or his/her designee.
(2) 
The application for change of zoning requests and preliminary subdivisions and/or land development plans which meet the aforesaid criteria shall not be considered complete until the transportation impact study is submitted to the Borough Council in accordance with the provisions of this section.
(3) 
Council, at its discretion, may require any other subdivision, land development, zoning change, special exception or conditional use application to be accompanied by a transportation impact study; provided, however, that the Council notifies the applicant immediately following Council's first meeting to consider the proposal. Such a notification shall specify the reason for the requirement, citing the proposal's particular location or existing problems or type of use (e.g., generation of heavy truck traffic).
D. 
Definitions.
CAPACITY ANALYSIS
The analysis compares the actual or projected traffic volume to the intersection capacity and results in a volume/capacity (v/c) ratio. Intersection approach capacity is the maximum rate of vehicular flow that can pass through an intersection under prevailing roadway, traffic and signalization conditions.
LANE GROUPS
Each individual vehicular movement that may be completed from an existing lane, such as a left turn, right turn, or through movement.
LEVEL OF SERVICE
Level of service (LOS) as described in the Highway Capacity Manual 2000, Transportation Research Board, is a qualitative measure of the operational conditions within a traffic stream and their perceptions by motorists. Levels of service are defined in terms of delay for signalized intersections and reserve capacity for unsignalized intersections. Six levels of service (A through F) are defined for a transportation facility. LOS A represents ideal operating conditions with no congestion, and LOS F represents a breakdown in operating conditions with severe congestion.
MAJOR INTERSECTION
Any intersection, either signalized or unsignalized, where traffic generated by the proposal may have an impact on the operation of the intersection. The transportation engineer shall seek guidance from the Borough Engineer prior to the initiation of the transportation impact study to ensure agreement on the location of major intersections.
OFF-SITE TRANSPORTATION IMPROVEMENTS
Other transportation improvements that are generally not contiguous with the property being developed and not required as an on-site improvement, but found to be necessary as a result of the proposed development.
ON-SITE TRANSPORTATION IMPROVEMENTS
All improvements on or adjacent to the development site in the public right-of-way required to be constructed by the developer pursuant to any ordinance, resolution or requirement of the Borough of Tullytown and/or directly related to the transportation needs of the subdivision and/or land development.
PUBLIC TRANSPORTATION
Transportation services for the general public provided by a common carrier of passengers generally, but not necessarily on a regular route basis, by the Southeastern Pennsylvania Transportation Authority or a private operator offering service to the public.
STUDY AREA
This area will extend along the adjacent roadways in all directions approximately 1/2 mile from the site access points. The study area will include all major intersections in the vicinity of the proposed development. The transportation engineer will seek guidance from the Borough Engineer prior to initiation of the transportation impact study to ensure agreement on the study area boundaries.
TRAFFIC SIGNAL WARRANTS
A series of tests that detail the minimum traffic or pedestrian volumes or other criteria necessary for the installation of a traffic signal. These warrants are outlined in the Manual on Uniform Traffic Control Devices for Streets and Highways, U.S. Department of Transportation, Federal Highway Administration, 1988, or as amended.
TRIP GENERATION RATES
The total count of vehicular trips to and from the study site per unit of land use, as measured by parameters such as square footage or dwelling units. Trip Generation, 7th Edition, or as amended, by the Institute of Transportation Engineers shall be referenced to determine trip generation rates.
E. 
General requirements and standards. A transportation impact study shall contain the following information:
(1) 
General site description. The site description shall include the size, location, proposed land use(s), construction staging, and completion date of the proposed land development. If the development is residential, a description of the types and number of dwelling units shall also be included. The general site description shall also include probable socioeconomic characteristics of potential site users to the extent that they may affect the transportation needs of the site (e.g., number of senior citizens). A brief description of other major existing and proposed land developments within the study area shall also be provided.
(2) 
Transportation facilities description.
(a) 
The description shall contain a full documentation of the proposed internal and existing external transportation system. This description shall include proposed 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 at all intersections 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 and designating bus shelter and sign locations where appropriate.
(b) 
The report shall describe the entire external roadway system within the study area. Major intersections in the study area shall be identified and illustrated. All existing and proposed public transportation services and facilities within a one-mile radius of the site shall also be documented. All regional rail stations within a three-mile radius of the site shall also be documented. All future highway improvements, including proposed construction and intersection signalization, shall be noted. This information shall be obtained from the latest Regional Transportation Improvement Program maintained by the Delaware Valley Regional Planning Commission. Any roadway improvements to be conducted in conjunction with surrounding land developments shall be recorded.
(3) 
Existing traffic conditions.
(a) 
Existing traffic conditions shall be measured and documented for all roadways and intersections in the study area, and shall include current average daily traffic volumes, peak highway hour(s) traffic volumes, and peak development-generated hour(s) traffic volumes. Traffic counts data shall not be more than one year old. Traffic counts shall be taken on a Tuesday, Wednesday, or Thursday of a non-holiday week. Additional counts (Saturday for a commercial or tourist attraction) may also be required in some cases. The individual or firm performing the transportation impact study shall obtain the traffic counts during average volume conditions during fair weather, and in consideration of any construction activities or special events which may otherwise affect traffic volumes of the roadway.
(b) 
Roadway characteristics shall be described and illustrated. Features to be addressed shall include lane configurations, geometry, signal timing, traffic control devices, posted speed limits, and sight distance limitations. Existing levels of service shall be calculated for all intersections and turning movements within the study area.
(c) 
This analysis will determine the adequacy of the existing roadway system to serve the existing traffic demand. Roadways, signalized intersections, or individual movements experiencing levels of service below C, and v/c ratios greater than or equal to 1.0 shall be noted as deficient. Unsignalized intersections with levels of service below D shall also be noted.
(4) 
Transportation impact of development.
(a) 
Estimation of vehicular trips to result from the proposal shall be completed for the average daily trips, average daily peak highway hour(s) and peak development-generated hour(s). Vehicular trip generation rates to be used for this calculation shall be obtained from Trip Generation, 7th Edition, as amended. For land uses not listed on the document, the transportation engineer shall seek guidance from the Borough Zoning Officer.
(b) 
All turning movements shall be calculated. These generated volumes shall be distributed to the study area and assigned to the existing roadways and intersections throughout the study area. Documentation of all assumptions used in the distribution and assignment phases shall be provided. Traffic volumes shall be assigned to individual access points. Pedestrian volumes shall also be calculated, if applicable. If school crossings are to be used, pedestrian volumes shall be assigned for each crossing. Any characteristics of the site that will cause particular trip generation or distribution problems shall be noted.
(5) 
Analysis of transportation impact.
(a) 
The total future traffic shall be calculated, and shall consist of the existing traffic volume expanded to the project completion year using an annual background growth factor plus the development generated traffic and the traffic generated by other developments in the study area. The annual background growth factor shall be determined using the projected rates of population and employment growth as determined by the Bucks County Planning Commission, the average annual traffic growth of the area's roadways as determined from the Delaware Valley Regional Planning Commission's Highway Network Coverage Traffic Counts or the Bucks County Planning Commission's traffic count database, and current twenty-four-hour traffic counts.
(b) 
The delay analysis shall 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 development shall be made.
(c) 
The analysis shall be performed for the peak highway hour(s) and peak-development-generated hour(s) for all roadways and intersections in the study area. Delay calculations shall be made for all intersections in the study area as well as for all access points into the development. It is usually at these locations that capacity is most restricted. A volume/capacity analysis shall be conducted for all intersections having a future level of service below C.
(d) 
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.
(6) 
Conclusions and recommended improvements.
(a) 
Levels of service and volume/capacity ratios shall be listed for all roadways and intersection lane groups. All roadways, signalized intersections, and/or lane groups showing levels of service below C and volume/capacity ratios greater than or equal to 1.0 shall be considered deficient. Specific recommendations for the elimination of all deficiencies shall be listed, and shall include but not be limited to the following elements: internal circulation design, site access location and design, external roadway intersection design and improvements, traffic signal installation and operation, including signal timing, and transit design improvements. All physical roadway improvements shall be illustrated. Signal timing should be evaluated for any intersection with a level of service below C but a volume/capacity ratio less than 1.0. Warrants for signalization shall be examined for all unsignalized intersections operating at deficient levels of service.
(b) 
The study shall outline mitigation measures and demonstrate any changes to the level of service achieved by these measures. Any alternatives or suggested phasing of improvements shall be described. The mitigation measures may include recommendations such as roadway widening, turning lanes, deceleration lanes/tapers, changes to signalization, use of access management techniques or a reduction in the proposed intensity of use. The responsibility and timing of all recommended roadway improvements shall be described within the transportation impact study.
(c) 
Existing and/or future public transportation service shall also be addressed. Listings of all actions to be taken to encourage public transportation usage for development generated trips and/or improve existing service, if applicable, shall be included.
