A. 
The construction of subdivision or land development improvements is the responsibility of the developer insomuch as it is his property which is being developed. Adequate streets, utilities and other improvements are essential elements in the creation and preservation of stable residential, commercial and industrial areas, and must be completed by the developer.
B. 
All of the following improvements, as required by the Township pursuant to the authority granted in the Pennsylvania Municipalities Planning Code, Act 247, as amended,[1] shall be completed in accordance with the requirements established by this chapter prior to final approval of the plan, except as otherwise provided herein.
[1]
Editor's Note: See 53 P.S. § 10101 et seq.
C. 
Final plan approval, except for minor subdivisions or land developments and replats, shall not be given prior to the completion and acceptance of all subdivision or land development improvements.
Utility and street improvements shall be required in each new subdivision or land development as follows, except that improvements are not required in existing public streets which may be incorporated into, or be adjacent to, the subdivision or land development:
A. 
Survey monumentation.
B. 
Water supply.
C. 
Sanitary sewage conveyance.
D. 
Storm sewers outside of public streets.
E. 
Streets, including required grading, subgrade, preparation, underdrains, base and paving.
F. 
Subgrade drains where necessary.
G. 
Curbing on streets.
H. 
Sidewalks (if required).
I. 
Seeding between the sidewalk and curb.
J. 
Required utilities, streetlighting, street name signs and required grading.
K. 
Erosion control, as needed.
L. 
Street trees.
The construction of improvements shall be in accordance with the requirements of this article. It is the intent of these regulations that all construction requirements shall be for the purpose of establishing a standard of quality and durability.
Survey monuments and markers shall be placed at all points as determined by the following criteria:
A. 
Monuments shall be concrete with a 3/8 inch metal dowel in the center at the top. Monument size shall be no less than four inches by four inches by 30 inches.
B. 
Markers shall be ferrous metal pipe or rods, 1/2 inch minimum diameter by 18 inches minimum length or may be standard manufactured steel survey markers of similar length.
C. 
Monuments shall be placed so that the center point shall coincide exactly with the intersection of lines to be marked.
D. 
Monuments shall be placed so that they protrude approximately two inches above grade in areas which are not paved, at grade if in a paved area not subject to vehicle traffic, and four inches to eight inches below grade if in a paved area subject to vehicle traffic. Monuments set in areas subject to traffic shall be protected with a cast iron frame and access cover of adequate design for truck traffic.
E. 
Markers shall be driven into the ground so as to be approximately flush with the final grade.
F. 
Monuments shall be set at the intersection of all lines forming angles in the boundaries of major subdivisions or land developments and at all street angle points, and at the intersection of all street center lines.
G. 
Markers shall be set at all lot angles and corners, and at the beginning and end of all curves in lot and street lines. Curves for corner radii at intersection need not be marked if the intersection is monumented.
A. 
The developer shall contact the West View Water Authority to determine the adequacy of a public water supply system. Prior to the approval of the preliminary plan, the developer shall provide documentation to the Planning Commission that arrangements for the provision of public water service are proceeding satisfactorily.
B. 
Fire hydrants shall be provided concurrently with the water supply at locations reviewed and approved by the Fire Marshal.
C. 
If a development requires such additional water supply as to require changes to the Township's water distribution system (West View Water), the developer is required to pay a share of the costs consistent with the provisions of Act 203 of 1990. It is the purpose of these regulations that developments which occur under this chapter shall pay their fair share toward needed improvements as set forth by Act 203 of 1990.
D. 
When the West View Water Authority system is reasonably available (within 1,000 feet), each lot in the subdivision or land development application shall be provided a complete on-site system with connections to the West View Water System in accordance with the minimum standards approved by the Pennsylvania Department of Environmental Protection.
A. 
Where a public sanitary sewer system is within 1,000 feet of an approved subdivision or land development and where required by the Township, the developer shall construct a sanitary sewer system and provide lateral connections for each lot in accordance with the specifications of the Township. Kilbuck Township Resolution No. 99-27, Sewer System Rules and Regulations, provides all applicable construction standards and details for sanitary sewer systems.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
B. 
The developer shall secure from the Township Engineer, prior to the approval of the preliminary plan, a letter indicating the general design, location and preliminary approval of the proposed sanitary sewer collection system. No plat shall be finally approved or recorded until the plans and specifications for sanitary sewage facilities have been approved and permits issued, as required, by the Health Department and/or the Department of Environmental Protection standards, and its approval/acceptance by the Township Engineer.
C. 
Private sewer facilities. When private sanitary sewer systems using individual treatment are provided, a statement shall be submitted by the developer to the Township from the Pennsylvania Department of Environmental Protection certifying that a permit has been issued by the appropriate agency approving the proposed facilities. Adequate security for the maintenance of such plan shall be furnished to the Township.
D. 
On-lot sewage disposal. In subdivisions or land developments where public sewers are not available and a complete private sanitary sewer system is not required by the Department of Health and/or the DEP, on-lot sewage disposal systems shall be provided. In such instances, the developer shall provide evidence that the planning module required for on-lot disposal by DEP has been approved. The developer must show compliance with Act 537,[2] and other state, county, or local law and/or regulation governing on-lot sewage disposal.
[2]
Editor's Note: See 35 P.S. § 750.1 et seq.
E. 
Capped sewer system. Where the sanitary sewer system is not yet accessible, but is planned for extension to the subdivision or land development, the subdivider or developer shall install sewer lines, including lateral connections, in order to provide service to each lot. The sewer mains shall be suitably capped at the limits of the subdivision or land development and laterals shall be capped at the street right-of-way line when not extended to houses or other structures; the internal plumbing system shall be constructed to accommodate them as well as any septic system required.
A. 
A drainage system adequate to serve the needs of the proposed natural waterways, and overland flow will be required in new subdivisions or land developments. The developer shall construct a storm sewer system and connect the drainage system with the Township's. Standard construction details for sanitary sewers are included in Township Resolution No. 99-27. Storm drainage construction details are typically approved on a case-by-case basis by the Township Engineer.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
B. 
If a development generates such additional storm drainage sewer flows as to require changes to the Township's storm sewer collection system, the developer will be requested to pay a share of the cost consistent with the provisions of Act 203 of 1990. It is the purpose of these regulations that developments which occur under this chapter shall pay their fair share toward needed improvements as set forth by Act 203 of 1990.
C. 
Bridges or culverts shall be designed to support and carry loads according to the requirements of the Township Engineer, 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.
D. 
Where open watercourses are planned, adequate safety, erosion control, drainage, protection of capacity and appearance measures shall be taken by the developer to insure proper, safe, healthful disposal of stormwater. All open watercourses must be approved by the Township Engineer.
E. 
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 by the Township Engineer where such required grades cannot be achieved.
F. 
Storm sewers shall have a minimum diameter of 15 inches and a minimum grade of 1/2 of 1%. Lesser grades may be permitted when substantiated with calculations which prove that cleaning velocities will be maintained.
G. 
Manholes shall normally be spaced at 300 feet maximum spacing where pipe sizes of 24 inches or less are used, and not over 400 feet where larger sizes are installed. Inlets may, if approved by the Township Engineer, be substituted for manholes.
H. 
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 certified by the Township Engineer.
A. 
Streets shall be graded to the full width of the right-of-way, surfaced, curbed (if required), and improved to the grades and dimensions shown on plans, with profiles and typical cross sections submitted by the developer and approved by the Township Engineer.
B. 
Side slopes shall be graded to blend with the natural lay of the land, or in accordance with cross sections submitted and approved by the Township Engineer. Where fill material is in accordance with the Pennsylvania Department of Transportation (PennDOT) Form 408 Specifications for Embankment, a slope of two horizontal feet to one vertical foot beyond the right-of-way line in cut or fill shall ordinarily be 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 as required by the Township Engineer. It shall be compacted at optimum moisture content. The finish 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 CBR value of 2.5 or less, will not develop the required stability or 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 designed and installed per the specifications of the Township Engineer.
E. 
All pavement, base, subbase (where required), and sidewalks shall conform to the requirements of the Township Engineer.
F. 
Areas between the sidewalk and curb (if required) shall be seeded as required by the Township Engineer.
Gas, electric and telephone utilities shall be located in subdivisions or land developments in accordance with utility company practice and in accordance with agreements with, or as approved by, the Township Engineer.
In wooded areas, floodplains, wetlands, areas having slopes of 25% or greater where other natural conditions exist in such a manner that development would be hazardous to the safety of life and property or would cause permanent ecological instability, the Township may require that the developer preserve as much of the original natural conditions as is ecologically practicable and may limit the amount of grading and excavation to the minimum improvement standards included herein.
It shall be a requirement of all major subdivisions or land developments that the developer shall have a soil erosion and sedimentation control plan and/or permit, prepared in accordance with current state law (Erosion and Sedimentation Control, Chapter 102, Pennsylvania Rules and Regulations, as amended), reviewed by the Allegheny County Conservation District and determined to be adequate. The county may also require a like plan for any minor subdivision or land developments. The plan shall be fully implemented during the construction of the development.
A. 
The Board of Supervisors shall insure, through receipt of certificates of compliance from the appropriate official, that required improvements have been installed according to specifications on the final plat, or alternately that adequate surety for such improvements have been posted.
B. 
A fee to be fixed by the Board of Supervisors covering the cost of inspection by the Township Engineer during the construction of the improvements of said subdivision or land development must be paid to the Township. The Township Engineer, his or her representative, or any other public official responsible for publicly owned utilities shall issue certificates of approval to the Board of Supervisors upon completion of the improvements in accordance with the standards and specifications herein contained.
C. 
Alternately, the process may be modified so that the subdivider may file with the Board of Supervisors a performance bond or other surety acceptable to the Board, the amount to be fixed by the Board in a form satisfactory to the Township Solicitor for the installation or completion of improvements not yet constructed. In fixing the amount of said bond or other assurance, the Board of Supervisors shall give due consideration to the cost of the required improvements as estimated by the Engineer or Township authority having jurisdiction over the local roads, publicly owned utilities and drainage facilities involved.
D. 
In lieu of the performance bond, a deposit may be made, either with the Township Treasurer or responsible escrow agent or trust company, of money or negotiable bonds in an amount equal to the estimated construction costs of such improvements. If a cash deposit is made, an agreement may be executed to provide that progress payments may be made to the contractor or the subdivider out of the deposit as the work progresses and is approved by the responsible Township official.
E. 
The development of existing dedicated streets and the extension of the public utilities may be provided by one of the above methods described or an alternate method may be used whereby the adjoining property owners petition the Township and, upon proper action, the improvements are provided and the costs assessed to them in accordance with the procedure outlined in the Township Code.
