A. 
The following land subdivision and land development principles, standards and requirements will be applied by the Township in evaluating 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, morals, and general welfare.
C. 
Whenever other applicable regulations impose more restrictive standards and requirements than those outlined herein, such other regulations shall control.
D. 
Where literal compliance with the standards specified herein is clearly impractical, the Township may modify or adjust the standards to permit reasonable utilization of property while securing substantial conformance with the objectives of these regulations.
A. 
No lot shall be subdivided under the provisions of this chapter if any part thus created shall not be usable under the provisions of the Zoning Ordinance of Hatfield Township.[1]
[1]
Editor's Note: See Ch. 282, Zoning.
B. 
Reserve strips shall be public rights-of-way controlling access to lots, other public rights-of-way, public lands or adjacent private lands. All other types of reserve strips shall be prohibited.
C. 
In general, lot lines shall follow Township boundary lines rather than cross them.
D. 
Wherever possible, developers shall preserve trees, wooded areas, groves, wetlands, scenic points, historic spots and other community assets and landmarks.
E. 
Subdivisions and land developments shall be laid out so as to avoid the necessity for excessive cut or fill or large-scale clearing of vegetation.
F. 
Land subject to flooding or other hazards to life, health, or property, and land deemed to be topographically unsuitable, shall not be platted for residential occupancy nor for such other uses as may increase danger to health, life or property, aggregate erosion or flood hazard, until all such hazards are provided for by the development plans. Such land within the subdivision or land development shall be set aside on the plat for uses as shall not be endangered by periodic or occasional inundation and shall not produce unsatisfactory living conditions.
G. 
Where flooding is known to have occurred within the area shown on the plan or any area is deemed a floodway or floodplain area in accordance with the Township Floodway Map or Township ordinance, such area shall be clearly marked "subject to periodic flooding."
H. 
Subdivisions and land developments shall be in strict conformity with the floodplain regulations of the Zoning Ordinance, building codes and as specifically provided under § 250-60.
A. 
General.
(1) 
The arrangement, character, extent, width, grade and location of all streets shall be considered in relation to existing and planned streets, to topographical conditions, to public convenience and safety, and in their appropriate relation to the proposed uses.
(2) 
Proposed streets shall further conform to such 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 Township ultimate right-of-way plans as developed by the Township Board of Commissioners.
(3) 
Streets shall be logically related to topography so as to produce reasonable grades, satisfactory drainage and suitable building sites.
(4) 
Residential streets shall be laid out as to discourage through traffic; however, the arrangement of streets shall provide for continuation of existing or platted streets and for proper access to adjoining undeveloped tracts suitable for future subdivision.
(5) 
If lots resulting from original subdivision are large enough to permit resubdivision, or if a portion of the tract is not subdivided, adequate street rights-of-way to permit further subdivision shall be provided as necessary. A schematic plan of any future lots shall be provided for review and approval.
(6) 
Dead-end streets shall be prohibited, except as stubs to permit future street extension into adjoining tracts or when designed as culs-de-sac.
(7) 
Where a land development relates to or a subdivision abuts or contains a present or proposed expressway or arterial highway, the Board of Commissioners shall:
(a) 
Require reverse frontage with screen planting contained in a nonaccess reservation along the rear property line (property line adjacent to expressway or arterial highway), a marginal access street, and/or such other treatment as may be necessary for adequate protection of all abutting properties and to afford separation of through and local traffic. In the case of collector highways, reverse frontage shall be required when practical.
(b) 
Screening, through the use of appropriate plant materials, fences or walls subject to site plan review, shall be provided in a strip of land along the rear property line of lots with reverse frontage (lot line along the feeder, collector or controlled access street) to buffer lots from the higher-order street.
(c) 
Where a service road or reverse frontage is provided, the improvements to the higher-order street shall be provided as part of the construction improvements for the project. Where a land development or subdivision relates to property that abuts a feeder, collector or controlled-access street, and which for a service road, marginal access street or reverse frontage lot is not possible, area shall be reserved on such property for the future placement of a service or marginal access street at such time as adjacent parcels are developed.
(d) 
Where the provision of a service road, marginal access street and/or reverse frontage becomes impractical or unnecessary, the lot or lots in said development shall have driveways so laid out that it is possible to turn passenger vehicles on the lot and it is not necessary to back any passenger vehicles into the street, and access an area reserved for the placement of a service road or marginal access street in the future as set forth in above Subsection A(7)(c).
(8) 
Half street. Unless the existence of a half street requires that another half street be constructed to complete it, no half streets shall be permitted.
(9) 
Reserve strips controlling access to streets shall be prohibited except where control thereof is vested in the Township under conditions approved by the Board of Commissioners. When the subdivision adjoins unsubdivided acreage, new streets shall be provided through to the boundary lines of the development with temporary easements for turnarounds. Location of the connector streets shall be laid to be practical for development of the adjoining parcel.
(10) 
Stub streets greater in length than one lot depth shall be provided with a turnaround to the standards required for permanent culs-de-sac.
(11) 
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 within the Township, and all street names shall be subject to the approval of the Township Board of Commissioners.
(12) 
Private streets are prohibited.
(13) 
Reference shall be made to Article VI, § 250-49, of this chapter regarding required improvements.
(14) 
Reference shall be made to the Township Road Opening Standards, incorporated herein as Chapter 250, Appendix G, as amended from time to time.[1]
(15) 
Unloading or loading of construction equipment on any Township roads shall not be permitted, unless specifically authorized by the Township in writing. If authorization is permitted, matting or other approved methods to protect the road surface shall be used.
