[1] 
That the level of service at unsignalized and signalized intersections contiguous to the developer's property necessary to serve the proposed development by providing egress and ingress thereto (intersections through which at least 35% of the development's traffic must flow to gain access to the development) shall not as a consequence of the proposed development fall below Level of Service D, as specified in the Transportation Research Board, Special Report 209, Highway Capacity Manual 1985, published by the Transportation Research Board, Washington, D.C., 1985 or latest edition; provided, however, that the Board may grant relief from this criteria upon recommendation of the Township Engineer following a traffic study supplied by the developer justifying waiver of this provision and proof by the developer that the waiver will not substantially impair or affect public safety. This provision shall not be construed to preclude improvement of such intersections to retain at least a Level of Service D or better.
[2] 
The effect of the proposed development on the reserve capacity of public roads and road intersections providing access to the development and in the area of the development property shall be demonstrated.
[3] 
That improvements to the roads contiguous to the developer's property proposed as part of the improvements for the development, such as road widening, acceleration/deceleration lanes, traffic control devices and similar improvements, shall be sufficient to accommodate the additional traffic generated by the proposed development consistently with recognized traffic engineering design principles, including but not limited to those promulgated by PADOT.
A. 
Purpose. The regulations established in this section have been adopted to require and ensure that:
(1) 
Each dwelling unit and each commercial or industrial building in all subdivisions and land developments hereafter granted approval shall have an adequate and uninterrupted supply of potable water for domestic use.
(2) 
Each unit or building shall have an adequate and uninterrupted supply of water for purposes of fire protection.
(3) 
In each case where water is to be supplied to a subdivision or land development by means of a public water supply system, such system meets minimum standards controlling water storage and production capabilities for domestic and fire use.
B. 
Requirements. If the developer for subdivision or land development approval proposes that the subdivision or land development be served by public water, the developer shall:
(1) 
File with the preliminary plan application a report from the public water company proposing to provide public water which describes the volume of flow, static pressure and residual pressure at the fire hydrant nearest to the proposed subdivision.
(2) 
Based upon the foregoing information, submit a hydraulic study which demonstrates what volume of water and pressures are to be provided at the most critical points within the development. Critical points shall be determined by the developer's engineer, following consultation with the public water company, determined on the basis of the intensity of development and all other applicable engineering criteria.
(3) 
Contemporaneously with submission of the final plan only, submit a plan, provided by the public water company, showing the proposed design of the water distribution system. It shall be affirmatively demonstrated by the water company that the provision of public water to the development will not have the effect of degrading water service to the existing users of the public water system.
C. 
Review procedure for proposed public water supply system.
(1) 
The submissions required by Subsection B of this § 175-24 shall be reviewed by the Township Engineer in conjunction with the subdivision or land development application, who shall make a recommendation to Board with respect to the developer's compliance with the requirements of this section and the adequacy of the public water supply system. The Board expressly reserves the right, in its sole discretion, to require the developer, at the developer's cost and expense, to provide an independent engineering study and report verifying the adequacy and ability of the proposed public water system to supply adequate public water for the purposes described in Subsection A of this § 175-24 to the proposed subdivision or land development.
(2) 
Submission by the developer of the required report, hydraulic study and plan shall be considered essential, and no subdivision or land development application, whether preliminary or final, shall be accepted for review or granted approval without such submission. Modifications required by the Township Engineer to any proposed water distribution system or required as a result of an independent engineering study shall, if based upon reasonable engineering or design criteria, be a condition of any subdivision or land development approval.
D. 
Minimum water supply requirements.
(1) 
In all subdivisions and land developments served by public water, the following water pressure and gallonage requirements shall apply:
(a) 
Residential use. A minimum domestic pressure of 30 pounds per square inch shall be provided at each house to be connected to the water supply main. The system to which the residential unit is connected shall have sufficient capacity to supply a minimum of 300 gallons of water per residential unit per day within the subdivision or land development.
(b) 
Commercial or industrial use. A minimum domestic pressure of 30 pounds per square inch shall be provided at each commercial or industrial building connected to the water supply main. When a building wishes to connect to a public water system, a study will be made to determine if there is adequate water supply in the system to supply the building and its proposed use(s).
(2) 
For purposes of fire protection in residential districts, the system shall be demonstrably capable of providing fire flow water requirements for a minimum duration of two hours of not less than 500 gallons per minute at residual pressures of 20 pounds per square inch. Fire hydrants shall be spaced every 600 linear feet along the public water supply system within the subdivision or land development so as to ensure that each building is within a radius of 400 feet of a fire hydrant.
(3) 
For purposes of fire protection in commercial and industrial districts, a 1,000 gallons per minute (G/M) at 20 pounds per square inch (psi) residual pressure is required. Spacing of hydrants should be within 400 feet of all properties.
E. 
Approvals conditioned upon adequacy of public water supply. No subdivision or land development application proposing a public water supply system shall be granted preliminary or final approval unless the developer demonstrates by a fair preponderance of the credible evidence full compliance with the provisions of this § 175-24.

A. 
General requirements.
(1) 
Each lot shall have approved sewage facilities in accordance with the provisions of PADEP and the Chester County Department of Health.
(2) 
All sanitary sewer facilities shall be subject to the requirements of the Pennsylvania Sewage Facilities Act[1] and the rules and regulations thereunder of PADEP, including without limitation, those at 25 Pa. Code, Chapters 71 and 73, and the rules and regulations of the Chester County Department of Health.
[1]
Editor's Note: See 35 P.S. § 750.1 et seq.
(3) 
The developer shall provide the highest type of sanitary sewage disposal facility consistent with existing physical, geographical, and geological conditions of the site. The highest type of facility is considered to be a facility which provides adequate protection against pollution of the environment over the lifetime of the development.
(4) 
All lots which cannot be connected with an operational public or operational community sanitary sewage disposal system at the time of construction of a principal building shall be provided with an on-site sanitary sewage disposal system which shall, as a minimum requirement, meet the design standards of prevailing regulations of PADEP and the Chester County Department of Health.
(5) 
If required by PADEP and/or the Chester County Department of Health, all subdivisions and land developments proposing individual community subsurface or land application sewage systems shall provide either an alternative disposal area for a community sewage system or an alternative disposal area for each individual lot for on-lot disposal systems, which meet the required horizontal isolation or setback distances and other requirements under the rules and regulations of PADEP. When PADEP and/or the Chester County Department of Health requires the provision of alternative disposal areas, the Board shall require that the developer clearly indicate these areas on the final plan for each lot requiring such a system in the proposed subdivision or land development. Such alternative area shall be protected from disturbance or encroachment by a recorded restrictive covenant or other instrument approved by the Township Solicitor.
(6) 
In no case shall sanitary sewers and storm sewers be combined. No on-site sewage disposal system shall be connected with a capped sewer.
B. 
Sanitary sewage disposal systems.
(1) 
Wherever a developer proposes that individual on-site sanitary sewage disposal systems shall be utilized, the developer shall either install such facilities or shall require by deed restriction or other means and/or manner acceptable to the Board, as a condition of the sale or lease of each lot, that such facilities shall be installed by the purchaser of such lot or parcel at the time that the first principal building is constructed, and in accordance with these regulations.
(2) 
Where studies by the Township indicate that start of construction or extension of sanitary trunk sewers to serve the property being subdivided or developed appears probable within a period of five years, the Board may require the installation and capping of sanitary sewer mains and all laterals to the street right-of-way line. All mains shall be terminated at manholes or suitably capped as directed by the Township Engineer.
(3) 
Where any buildings are to be occupied or conveyed prior to the extension of a sewer system to the subdivision or land development, the subdivider shall install approved on-site sewage disposal facilities or require as a condition of sale that such facilities shall be installed in accordance with this § 175-25 in addition to the provision of capped sewers as required in Subsection B(2). The cost of such installation shall be the responsibility of the developer.
C. 
Soil suitability analysis requirements.
(1) 
Deep hole and percolation tests shall be performed for all subdivisions where proposed building(s) at the time of construction cannot be connected to a public or community sanitary sewage disposal in operation. Deep hole test pits are required in connection with the submission of completed planning modules for land development as part of the preliminary plan application.
(2) 
Deep hole and percolation tests shall be made in accordance with the procedure required by PADEP and the Chester County Department of Health by a registered professional engineer, registered sanitarian, or a sewage enforcement officer under the Pennsylvania Sewage Facilities Act,[2] at a rate of one deep hole test per lot prior to preliminary plan submission. The rules of the percolation and deep hole tests shall be prepared in accordance with Subsection C(3) below, and shall be made part of the submission of the completed planning module for land development required as part of the preliminary plan application in accordance with Article V of this chapter.
[2]
Editor's Note: See 35 P.S. § 750.1 et seq.
(3) 
The results of the above tests shall be analyzed in relation to the physical characteristics of the tract being developed and of the general area surrounding the tract. The lot layout of the preliminary and final plan shall be based on this analysis. The analysis shall indicate that each lot to be served by on-site sanitary sewage disposal facilities is of a size and shape to accommodate the necessary size of absorption area at a safe isolation distance from water supply wells and proposed and existing buildings, in accordance with the isolation distance rules and regulations of PADEP, as administered by the Chester County Department of Health. The location of the deep hole tests, the location and size of existing and proposed on-site sanitary sewage disposal facilities, and the location of existing and proposed buildings and water supply wells shall be shown on the preliminary and final plans.
(4) 
Backfilling of all percolation test holes and related test pits shall be accomplished within the time period specified in accordance with the Pennsylvania Sewage Facilities Act and/or the rules and regulations thereunder of PADEP.
D. 
Community systems. In such cases where public sanitary sewage disposal system is not available and an on-site sanitary sewage disposal system is not approved, the developer shall provide a complete community sanitary sewage disposal system. The design and installation of any such community sewage system shall be subject to the approval of the Township and PADEP, shall satisfy all PADEP standards relating to construction, installation and maintenance. The developer shall be required to enter into a written agreement with the Township providing for the developer's future operation, maintenance and upkeep of the facility and the establishment by the developer of an escrow account to fund operational and maintenance needs of the facility. A copy of the approval of such system shall be submitted with the final plan application or as soon as permitted by PADEP. If required by the Board, all such community systems shall be offered for dedication to the Township, but nothing herein shall require the Township to accept any proposed dedication.
E. 
Public sewerage systems. If the subdivision or land development is in an area served by a public sanitary sewage disposal system, the developer shall be required to connect to the system if capacity is available.
F. 
Facilities specifications. All sanitary collection systems and treatment facilities shall be installed according to the standards and specifications as adopted by the East Whiteland Municipal Authority.
G. 
On-lot systems. All individual on-site sewer systems shall be located on the lot they shall serve.
H. 
Sand-mound systems. If a sand-mound system is warranted, all sewage shall be aerated prior to being disposed of in the sand mound.
