Minimum improvements and construction standards required of all subdivisions shall be as set forth in this article and as listed in Table 3.[1] Where not set forth, they shall be in accordance with the prevailing standards as established by the Commission Engineer. Alternate improvement standards may be permitted if the Commission deems them equal or superior in performance characteristics to the specified improvements. Additional or higher-type improvements may be required in specific cases where the Commission believes it necessary to create conditions essential to the health, safety, morals and general welfare of the citizens of the municipality.

Editor's Note: See § 181-25.
Monuments shall be placed so that the scored or marked point shall coincide exactly with the intersection of the lines to be marked and shall be set so that the top of the monument or marker is level with the surface of the surrounding ground.
A. 
Monuments shall be readily visible and shall be set at the intersection of all lines forming angles in the boundary of the subdivision. Monuments may be of the following two types:
(1) 
Cut stone, six inches by six inches by 35 inches long, with a drill hole in the center.
(2) 
Concrete, six inches by six inches by 48 inches long, with a copper or brass pin in the center.
B. 
The proposed replacement of any existing monuments shall be clearly indicated on the final plan.
C. 
Five-eighths-inch copper weld or 3/4 inch reinforcing rod or 3/4 inch of pipe or iron pin markers shall be set at the beginning and ending of all curves along street property lines; at all points where lot lines intersect curves, either front or rear; at all angles in property lines of lots; and at all corner lots, markers shall consist of steel pipe at least 15 inches long and not less than 3/4 inch in diameter.
The provision of street pavement, curbs and sidewalks on all proposed or required public streets shall be as shown on Table 3. All streets shall be graded, surfaced and improved to the grades and dimensions shown on plans, profiles and cross sections submitted by the subdivider and approved by the Commission. Table 3 specifies those improvements which are the responsibility of the subdivider. In the case of arterial streets, the Pennsylvania Department of Transportation or the municipality may provide additional improvements over and above those required to be installed by the subdivider.

NOTES: The letters in Table 3 (A, B and C) refer to the following proposed construction standards of the Commission Engineer:
A
=
Street pavement, which shall consist of 2 1/2 inches of ID-2 surface course placed over a stone base course, both in accordance with the latest specifications of the Pennsylvania Department of Transportation. The thickness of the stone base course shall be 10 inches for arterial streets, eight inches for collector streets and six inches for local streets. Bituminous aggregate is an acceptable equivalent, as noted in the latest Pennsylvania Department of Transportation manual.
B
=
Portland cement concrete, six inches at the top, eight inches at the bottom and 21 inches in height. Concrete machine asphalt is an acceptable substitute.
C
=
Concrete sidewalk, four-inch thickness, minimum pounds per square inch (psi) of 2,500, placed on four inches' cinder or crushed stone base.
Street signs shall be provided at the intersections of all streets. The type, height and design shall be approved by the Commission.
A. 
Provision of water supply. Where public water supply, in the opinion of the Commission, is reasonably accessible, the subdivision shall be provided with a complete water distribution system, including a connection for each lot and appropriately spaced fire hydrants which shall not be greater than 1,000 feet apart. Where public water supply is not within reasonable distance, an alternate supply, approved by the Pennsylvania Department of Environmental Protection, shall be furnished.
B. 
Location of water lines. Where public water lines are installed, all such water lines shall be located between the curbline and the property line within any street right-of-way.
A. 
Public sewer system. Where the public sanitary sewer, in the opinion of the Commission, is reasonably accessible, sanitary sewers shall be installed to adequately serve all lots with connections to the public system. The public sewer system shall conform with the following:
(1) 
Where lots cannot be served by the extension of an existing public sanitary sewer, the subdivider shall conform to Chapter 210, Zoning.
B. 
Residential lot sizes. Lot dimensions, areas, yards and building setback lines shall be not less than specified by the provisions of Chapter 210, Zoning.
C. 
Capped sewers. Where the municipality has a plan for extending the public sanitary sewer system into an area that is being subdivided and it is reasonably expected that the area will be served by the public system within a period of five years, capped sewers shall be installed to adequately serve all lots in the proposed subdivision, as well as provisions set forth in Subsection A above.
D. 
Type of sewer system. No combined sanitary and storm sewer systems will be permitted.
E. 
Manholes. Sanitary and storm sewer manholes will be provided at all changes in grade and direction, and in no instance shall the distance between said manholes exceed 400 feet.
A. 
Provision of storm sewers. Storm sewers shall be installed when, in the opinion of the Commission, it is deemed necessary to provide adequate drainage for the subdivision.
B. 
Purpose of storm sewers. When storm sewers, culverts and related installations are provided, they shall be designed:
(1) 
To permit unimpeded flow of natural watercourses.
(2) 
To ensure adequate drainage of all low points along the line of streets.
(3) 
To intercept stormwater runoff along streets at intervals reasonably related to the extent and grade of the area drained and at all intersection streets.
C. 
Special problems. In the design of storm sewage installations, special consideration shall be given to avoidance of problems which may arise from concentration of stormwater runoff over adjacent properties.
D. 
Construction standards. All drainage structures, culverts, boxes, grates, etc., shall conform to the current specifications of the Pennsylvania Department of Transportation, as approved by the Commission Engineer.
A. 
Power, telephone and television community antenna lines. All subdivisions shall have easements provided for the installation of power and telephone utility lines to serve each and every lot, and provision shall be made, when necessary, for the location of television community antenna lines to be installed in said easements.
B. 
Gas transmission lines. When any subdivider proposes to provide gas transmission lines within a subdivision, said gas transmission lines shall be installed between the curbline and sidewalk.
C. 
Utilities consultation. Utilities serving the area of the proposed subdivision shall be consulted with respect to location, size and use of easements for utility purposes.
A. 
Methods to be followed. After approval of the preliminary plan, the subdivider shall install the required improvements under the supervision of the Commission Engineer. The subdivider may elect to carry out minimum improvements by any of the following methods:
(1) 
By installing the required improvements and obtaining from the municipality a certificate stating that all improvements have been installed in accordance with the standards and specifications contained in this article.
(2) 
By posting with the Commission a certified check or bond running to the municipality in an amount sufficient to cover the full cost of installing the required improvements as estimated by the Commission Engineer. In case of a bond filed, it shall also:
(a) 
Be with surety satisfactory to the Commission.
(b) 
Specify the time for the completion of the improvements and installations, such time to be satisfactory with the Commission.
B. 
Maintenance bond. In submitting the final plan to the Commission, the subdivider shall submit a maintenance bond to guarantee maintenance and repair of the streets in the subdivision for one year after the construction thereof has been approved by the Commission Engineer and acceptance of improvements has been consummated by the municipality.
