(Ord. 1286, passed 6-7-1982) Penalty, see § 154.999
(A) The developer shall construct a sanitary sewer system and provide lateral connections for each lot where a public sanitary sewer main is available at the plat boundary or within a reasonable distance thereto (within 1,000 feet of the subdivision).
(B) If a public sewer main is not available under the conditions stated above and the subdivision conatins ten lots or more, provisions shall be made by the developer to provide adequate sewage collection and treatment facilities, including a treatment plant or community disposal system, house lines, laterals, trunk lines, manholes, and other appurtenances as deemed mecessary by the city and/or the Department of Environmental Resources.
(C) If, in the opinion of the County Health Department, the Pennsylvania Department of Environmental Resources, the city and/or the Commission, factors exist which would create a public health and sanitation problem if a certain area is subdivided, the Commission will not approve the subdivision plan of such area until such factors are corrected by an adequate sanitary sewer system.
(D) All design and all phases of construction, including excavation, trench, pipe, grade, backfill, and manholes shall be in accordance with construction drawings approved by the State Department of Environmental Resources and shall be inspected by the City Engineer, city authorized representative, authority representative or other official as may be designated by the city.
(E) In areas where city sewers are planned to be available but not yet built, a sewer system shall be provided to the edge of the subdivision closest to the municipal trunk location and capped. Such system shall include all mains, laterals and other appurtenances herein required. Until such time as a municipal sewer becomes available, a project system must be installed. In the case of a project system, a trunk line shall be provided to connect into the municipal system.
(F) Where public sewers are not available or planned, and the subdivision contains less than ten lots, individual on-site disposal systems (septic-systems) may be provided, but must be approved and inspected by the County Health Department.
(G) The minimum diameter of any gravity sewer pipe main shall be eight inches and any lateral four inches. Six-inch gravity mains and grinder type pressure systems may be permitted for certain installations when approved by the County Health Department and the Pennsylvania Department of Environmental Resources.
(Ord. 1286, passed 6-7-1982)
(A) A drainage system adequate to serve the needs of the proposed new streets, natural waterways and overland flow will be required in new subdivisions. A drainage system may be composed of conduits, waterways, swales, ditches and curb flow areas, as required. When a public storm sewer main is available at the plat boundary or within 500 feet, the subdivider shall connect the drainage system with such storm sewer main if the grade permits and other more economical solutions are not possible.
(B) Bridges or culverts shall be designed to support and carry loads according to the requirements of the city, but not less than AASHTO Loading HS-20, and shall be constructed the full width of the cartway plus additional length as necessary to provide a proper installation.
(C) Where open watercourses are planned, adequate safety, erosion control, drainage, protection of capacity and appearance measures shall be taken by the developer to ensure proper safe and healthful disposal of storm water. All open watercourses must be approved by the Commission.
(D) Minimum grade of drainage courses shall be designed to create a minimum cleaning effect (velocity of two feet per second). Lesser grades may be permitted where such required grades cannot be achieved and the city approves lesser grades.
(E) Storm sewers shall have a minimum diameter of 15 inches and a minimum grade on .5%. Lesser grades may be permitted when substantiated with calculations which prove that cleaning velocities will be maintained.
(F) Manholes shall normally be spaced at 400 feet maximum spacing where pipe sized of 24 inches or less are used, and not over 600 feet where larger sizes are installed. Inlets may, if approved by the Commission and municipality be substituted for manholes.
(G) All phases of construction of open ditches, gutters, or storm sewers including width, depth, shapes, erosion control, minimum grade, size and area shall be in accordance with the requirements of these regulations and all storm drainage facilities shall be inspected and approved by the city.
(Ord. 1286, passed 6-7-1982)
(A) Streets shall be graded to the full width of the right-of-way, surfaced, and improved to the grades and dimensions shown on plans, curbed with profiles and typical cross-sections submitted by the developer and approved by the Commission. In subdivisions where sidewalks are not required, the sidewalk areas shall be graded in the same manner as if sidewalks were to be constructed and shall be brought to within six inches of final sidewalk grade.
(B) Side slopes shall be graded to blend with the natural lay of the land or in accordance with plans approved by the Commission. Where fill material is necessary to establish uniform grades, compacting shall be required in accordance with Pennsylvania Department of Transportation Form 408 Specifications for embankment. A slope of two horizontal feet to one vertical feet beyond the right-of-way line in cut or fill shall ordinarily be required except for unusual conditions. Street cross sections for minor and collector streets shall be in accordance with accepted standards and shall be approved by the city. Arterial street cross sections shall be as approved by the city and shall be approved by the state where required.
(C) The subgrade shall be shaped to rough lines and elevations equal to the width of the pavement plus two feet. Adequate drainage facilities shall be installed to provide for the disposition of underground seepage and the percolation of surface water. The subgrade shall be thoroughly compacted by power rollers with a minimum weight of ten tons to ensure satisfactory compaction and stabilization; it shall be compacted at optimum moisture content. The finished surface shall be uniformly shaped to facilitate drainage and any irregularities from planned grade shall be corrected prior to placing the subbase. Where material encountered in the normal excavation has a C.B.R. value of 2.5 or less and will not develop the required stability and provide for adequate drainage, the area shall be undercut and granular material added to a depth of at least 12 inches. It shall then be brought to a firm and thoroughly compacted surface as hereinbefore specified. The prepared subgrade shall be protected by the contractor to prevent undue rutting from trucks or other equipment and if such damage does occur, the subgrade shall be reshaped and compacted prior to placing the subbase material.
(D) Subdrains shall be laid along one side of all streets where there is apparent ground water percolation or soils are of an unstable type. Side or diagonal subdrains shall be installed where conditions require additional subdrainage. Side drains may require pipe in addition to stone backfill. The required interval for side drains shall be related to ground water conditions. The developer shall be fully responsible for proper subdrainage of all street improvements. The Commission may direct that additional subdrainage be added where conditions warrant. Subdrains shall generally be drained to storm sewer catch basins, inlets, or manholes, or to natural drainage channels.
(E) In general, all pavement, base, and subbase (where required) shall conform to the following requirements. It is the intent of these specifications to designate acceptable quality and any substitutions of materials or methods must be approved.
(1) The subbase:
(a) No subbase or other work above subgrade shall be commenced until all sewers, water, drainage and other buried appurtenances are installed and properly backfilled, and the subgrade is inspected and approved.
(b) The subbase (if required) shall be of approved materials as hereinafter designated for bank-run gravel base, and shall be installed and compacted in uniform layers in accordance with Pennsylvania Department of Transportation Specifications, Form 408, current edition, under the section entitled “Subbase”.
(c) The subbase shall be to plan grade, inspected and approved prior to installation of the base course.
