B. 
All improvements shall be constructed in accordance with the specifications of the Township.
C. 
The improvements included in this article are minimum requirements. However, the Board of Commissioners reserves the right, in any case, to increase the same if conditions so warrant.
When changes from the accepted drawings and specifications become necessary during construction, written acceptance by the Township, upon the advice of the Township Engineer, shall be secured before the execution of such change.
Adequate provisions for the satisfactory maintenance of all streets shall be made by dedication to and acceptance for maintenance by the Township or by other acceptable means.
A. 
The construction of streets and driveways as shown upon final plans and as contained in contract agreements shall in every respect conform to such requirements as the Township may, by resolution, require for the construction of streets.
B. 
All streets shall be graded to:
(1) 
The grades shown on the street profiles and cross-section plan submitted and approved with the final plan.
(2) 
The full width of the right-of-way; in wooded areas this may be modified to preserve existing trees.
C. 
Along the existing street on which a subdivision or land development abuts (hereinafter called a "boundary street"), improvements shall be made to the street. The improvements to the boundary street shall be determined by the width of the required cartway and built to the specifications established by the Township.

Editor's Note: See also Ch. 250, Streets and Sidewalks.
A. 
The Township shall erect, at the developer's expense, at every street intersection a street sign or street signs meeting Township approval, having thereon the names of the intersecting streets. At intersections where streets cross, there shall be at least two such street signs; and at the intersections where one street ends or joins with another street, there shall be at least one such street sign.
B. 
Street signs are to be erected when the first dwelling on the street is occupied. Temporary street signs may be erected on the approval of the Township, but shall be made permanent before final offer for the dedication of roads is made.
C. 
Warning and regulatory signs shall be erected along streets as required by the Board of Commissioners.
Where appropriate, the developer shall install or cause to be installed, at the developer's expense, metal or fiberglass pole streetlights serviced by underground conduit in accordance with a plan to be prepared by the developer's engineer and approved by the Board of Commissioners and by the Philadelphia Electric Company. The equipment of metal or fiberglass poles may be waived in such instances as approved by the Board of Commissioners due to the existence of wooden poles already in place. Provisions shall be made for energizing said lighting after 50% or more of the dwellings in a given subdivision or land development or section of a subdivision or land development have been occupied. The developer shall be responsible for all costs involved in lighting the streets until such time that the streets are accepted or condemned as public streets by the Township.
A. 
Monuments shall be placed in each change in direction of street-line boundary; two to be placed at each street intersection and one on each side of any street at angle points and at the beginning and end of curves. Areas to be conveyed for public use shall be fully monumented at their external boundaries.
B. 
Monuments shall be placed in the ground after final grading is completed, at a time specified by the Township Engineer.
C. 
All monuments may be checked for accuracy by the Township Engineer or their accuracy certified by the owner's engineer or surveyor. Accuracy of monuments shall be within 3/100 of a foot.
A. 
Sidewalks shall be constructed as required by § 255-27C. These standards shall apply on all new streets and on existing streets, unless in the opinion of the Board of Commissioners they are unnecessary for public safety and convenience.
B. 
All sidewalks shall be constructed in accordance with § 255-37 of this chapter.
C. 
The alignment and gradient of walks shall be coordinated with the grading plan to prevent the passage of concentrated surface water on or across the sidewalk and to prevent the pocketing of surface water by sidewalks.

Curbs shall be provided as required in § 255-27C, unless in the opinion of the Board of Commissioners they are unnecessary.
B. 
Curbs, where required, shall be the vertical type and constructed in accordance with Township specifications.
The developer shall construct stormwater drainage facilities, including curbs, catch basins, inlets, storm sewers, culverts, road swales, open channels and other structures in order to prevent erosion, flooding and other hazards to life and property. All such facilities are to be of adequate size and grade to hydraulically accommodate maximum potential volumes of flow; and size, type and installation of all storm drains and sewers shall be constructed in accordance with approved plans. The Township shall have the option of requiring that those areas set aside as retention or catch basins shall be dedicated to the Township.
[Amended 6-11-1990 by Ord. No. 90-27]
A. 
The developer shall construct water mains in such a manner as to make adequate water service available to each lot or dwelling unit within the subdivision or land development. A minimum pressure of 20 pounds per square inch shall be provided at each house or other building to be connected to the water supply main. The water supply must comply with the regulations and the standards of the Department of Environmental Resources. Said supply shall be located and constructed so as to eliminate the possibility of flood damage.
B. 
The system shall also be designed with adequate capacity and appropriately spaced fire hydrants for fire-fighting purposes pursuant to the specifications of the National Fire Protection Association. Review and approval by the Township Engineer and the Township Fire Marshal shall be required in order to ensure that adequate fire protection is provided. Therefore, any and all subdivision and land development plans submitted to this Township shall indicate, according to scale, the closest existing fire hydrant to the proposed subdivision and land development.
C. 
Where water is to be provided by means other than by private wells owned and maintained by the individual owners of lots within the subdivision or development, the applicant shall present evidence to the Board of Commissioners that the subdivision or development is to be supplied by a certified public utility, a bona fide cooperative association of lot owners or by a municipal corporation, authority or utility. A copy of a certificate of public convenience from the Pennsylvania Public Utilities Commission or an application for such certificate, a cooperative agreement or a commitment or agreement to serve the area in question, whichever is appropriate, shall be acceptable evidence.
[Added 10-22-1990 by Ord. No. 90-49]
Where no public water is accessible, water shall be furnished by the developer on an individual lot basis. If wells are installed on each lot and the lot also contains its own sewage disposal facilities, the well shall be of the drilled type, cased and grout-sealed into the bedrock. The well will be required to have a production of not less than six gallons per minute as established by bailor tests and certified by the well driller. Before being placed in consumer use, it shall be disinfected by the use of sodium hypochlorite or other acceptable solutions and a sample bacteriological examination collected by a licensed water analyst.
A. 
Wherever practical, sanitary sewers shall be installed and connected to an appropriate public sewer system. Where a sanitary sewer is not yet accessible but is planned for extension to the subdivision within 10 years, the developer shall install sewer lines, including lateral connections, as may be necessary to provide adequate service to each lot when connection with the public sewer system is made. The sewer lines shall be suitably capped at the limits of the subdivision, and the laterals shall be capped at the right-of-way line. The sewer installation shall include construction within rights-of-way or easements to bring the sewer to the future connection with the public sewer system.
