DESIGN STANDARDS
§ 155.065  MOST STRINGENT REQUIREMENTS TO APPLY.
   In all land developments and subdivisions developed after the effective date of this chapter, certain improvements shall be installed in accordance with design specifications set forth herein. Whenever the township standards, in applicable zoning ordinances, building codes, road ordinances or other ordinances, resolutions or regulations require standards that exceed these minimum standards, those township standards shall apply. Whenever the standards of this chapter exceed those of the other municipal ordinances, the standards of this chapter shall apply.

   (A)   Land subject to flooding and land deemed by the township to be uninhabitable for other reasons shall not be platted for residential occupancy, nor for such other uses as may increase danger to health, life, property, groundwater or aggravate the flood hazard; but such land within a plan shall be set aside for such uses as will not be endangered by periodic or occasional inundation or as will not endanger life, property or further aggravate or increase the existing menace. Any development within a floodway shall be in accordance with the applicable DEP permit.
   (B)   Areas characterized by steep slopes (slopes greater than 15%), geologic formations, sink holes, wetlands or other such features which restrict the usability of the land shall not be subdivided or developed.
   (C)   In determining the suitability of land for subdivision, the township shall refer to applicable studies by the County Planning Commission, state and federal agencies, including the soil survey prepared by the United States Department of Agriculture, Natural Resources Conservation Service.
   (D)   The layout or arrangement of the subdivision or land development shall conform to the County Comprehensive Plan, the Township Comprehensive Development Plan and to any regulations or maps adopted in furtherance thereof; in addition, the layout or arrangement of the subdivision or land development shall conform to any local level Comprehensive Plan or other applicable ordinances which may exist.
   (E)   Where evidence indicates that the minimum lot size requirements specified in other sections of this chapter or in any applicable zoning ordinance are not adequate to permit the installation of individual on-lot water and/or sewage disposal facilities, along with an area to be set aside for a replacement sewage absorption bed, the township shall require that the Township Sewage Enforcement Officer (SEO) or the State Department of Environmental Protection (DEP) make such tests as are necessary to determine the adequacy of the proposed facilities in relation to the provisions of the State Sewage Facilities Act 537, 35 P.S. §§ 750.1 et seq., as amended, plus other applicable state or local regulations. The township shall review and shall make a final determination on the adequacy of the proposed facility.

      (10)   All street construction shall be inspected by the township. The contractor shall notify the township 14 days prior to the time when inspection is required. The contractor may not under any circumstances proceed with subsequent stages until authorization to proceed is given by the township.

*Note: the Board of Supervisors reserves the option to allow the determination of right-of-way width, cartway width, shoulder width and minimum and maximum grades, of collector and arterial streets to be determined on the basis of a traffic study furnished by the applicant, and reviewed and accepted by the Township Engineer
 
   (C)   Alignment. Minimum street alignment standards shall conform with the horizontal curvature requirements of the Rural Design Criteria as per the Design Manual Part 2 Highway Design, Publication 13, PennDOT Bureau of Design, latest edition. Proper sight distance shall be provided with respect to both horizontal and vertical alignment in accordance with A Policy on Geometric Design of Highways and Streets, American Association of State Highway and Transportation Officials (AASHTO), Chapter IX, latest edition.
   (D)   Grades. Minimum street grade standards shall conform with the vertical grade requirements of the Rural Design Criteria as per the Design Manual Part 2 Highway Design, Publication 13, PennDOT Bureau of Design, latest edition, up to a maximum grade of 10%.
   (E)   Horizontal curves. Minimum horizontal curves shall conform with the horizontal curvature requirements of the Rural Design Criteria as per the Design Manual Part 2 Highway Design, Publication 13, PennDOT Bureau of Design, latest edition.
   (F)   Vertical curves. Vertical curves shall be provided of sufficient length to provide the safe sight distance for the design speed in accordance with A Policy on Geometric Design of Highways and Streets, American Association of State Highway and Transportation Officials (AASHTO), Chapter IX, latest edition.
   (G)   Intersections. The following standards shall apply to all street intersections.
      (1)   Streets shall intersect as nearly as possible at right angles. No street shall intersect another at an angle less than 75 degrees or more than 105 degrees.
      (2)   No more than two streets shall intersect at the same point.
      (3)   Streets intersecting another street shall either intersect directly opposite to each other or shall be separated by at least 125 feet between centerlines measured along the centerline of the street being intersected.
      (4)   Intersections with major streets shall be located not less than 1,000 feet apart measured from centerline to centerline along the centerline of the major street.
      (5)   Street curb intersections shall be rounded by a tangential arc with a minimum radius of:
         (a)   Twenty feet for intersections involving only minor streets;
         (b)   Thirty feet for all intersections involving a collector street; and
         (c)   Forty feet for all intersections involving a major street.
      (6)   Street right-of-way lines shall be parallel to (concentric with) curb arcs at intersections.
      (7)   Clear sight triangles shall be provided at all street intersections. No buildings or obstructions are permitted in the area and such triangles shall be established from a distance of 15 feet behind the edge of pavement to the point:
         (a)   Seventy-five feet from the intersection of centerline for minor streets; and
         (b)   One hundred fifty feet from the intersection of centerline for all intersection with major streets.
      (8)   Minimum sight distance shall be provided at all street intersection in accordance with the State Code, Title 67, Chapter 441, § 8(h).
      (9)   Leveling areas shall be provided at all street intersections having not greater than three percent grades for a distance of 50 feet measured from the nearest cartway edge of the intersecting streets.
   (H)   Alleys. Alleys shall not be permitted in residential subdivisions except in cases where other methods of entrance and exit are impractical. In other types of development, where permitted, their design standards shall be determined by the township.
   (I)   Names. The subdivider may choose street names subject to the approval of the township. Proposed streets which are in alignment with others already existing and named shall be assigned the names of the existing streets. In no case shall the name of a proposed street duplicate or confuse an existing street name in the township, irrespective of the use of the suffix street, road, avenue, boulevard, driveway, place, court, lane and the like.

§ 155.068  BLOCKS.
   (A)   Determination. The length, width and shape of blocks shall be determined with due regard to the following:
      (1)   Provision of adequate sites for building of the type proposed;
      (2)   Topography;
      (3)   Requirements for safe and convenient vehicular and pedestrian circulation; and
      (4)   Other site constraints.
   (B)   Width. Blocks subdivided into lots will be two lot depths in width, excepting lots along a major thoroughfare which front on an interior street or are prevented by the site topographic conditions or other inherent conditions of the property, in which case the township may approve a single tier of lots.
   (C)   Length. All blocks in a subdivision shall have a maximum length of 1,200 feet and a minimum length of 400 feet. Blocks over 600 feet in length shall require crosswalks wherever necessary to facilitate pedestrian circulation and to give access to community facilities. Such crosswalks shall have a width of not less than ten feet and a stabilized walkway of not less than five feet.
