Streets shall be graded to grades and cross sections as presented with the preliminary plats and street profiles and as approved by the Township Board of Supervisors on the final plat or land development.
Streets shall be graded to the full width of the right-of-way and slopes of a minimum to two feet of rise to one foot of run shall be constructed commencing at the street right-of-way and extending onto the lots of properties adjoining the street right-of-way. This applies to both cut and fill sections.
Subgrade of street shall be brought to the proper grade and cross section as approved by the Township Engineer and shall be rolled with a ten-ton roller. All soft spots shall be removed. These soft spots shall be recompacted with a suitable material approved by the Board of Supervisors upon recommendation by the Township Engineer before the placing of any base material.
No base course shall be placed until subgrade has been inspected and approved by the Township Engineer.
In areas where springs, poor soil drainage conditions, wet weather springs or where conditions exist that underground drainage is necessary to properly protect the proposed street pavement, there shall be constructed pipe underdrain, stone underdrain or subgrade drains according to current Pennsylvania Department of Transportation Specifications, Form 408, subject to approval of drawings and design and materials by the Township Board of Supervisors.
If during construction unknown poor drainage conditions are encountered by the owner, he shall notify the Township Engineer and correct such conditions encountered at the direction of the Board of Supervisors upon recommendation of the Township Engineer to its complete satisfaction.
The type of curb used and location shall be determined by the Township Board of Supervisors and subject to its approval upon the recommendation of the Township Engineer before installation of the same.
The base course shall be constructed to the lines, grades and cross sections as given final approval, with all materials used and all construction requirements performed in conformity with current Pennsylvania Department of Transportation Specifications, Form 408, and be one of the following approved types of base course material:
A subbase shall be constructed when required by the Township of a crushed aggregate material as approved by the Township Engineer where soil or traffic conditions warrant its use, with a compacted thickness of not less than three inches in depth.
The surface course shall be constructed to the lines, grades and cross sections as given final approval, with all materials used and all construction requirements performed in compliance with current Pennsylvania Department of Transportation Form 408 specifications and be one of the following types of materials:
A bituminous surface course (ID-2) with a compacted thickness of not less than 2 1/2 inches in depth shall be placed on a crushed aggregate base course. The binder course shall be 1 1/2 inches in depth, and the wearing course shall be one inch in depth.
A bituminous wearing course (ID-2) with a compacted thickness of not less than one inch in depth shall be placed on a bituminous concrete base course.
Sidewalks shall be constructed of concrete four inches in thickness; except at driveways, where they shall be a minimum of six inches in thickness. Sidewalk shall be a minimum of 60 inches in width.
Storm sewers shall be located in the street right-of-way or in a drainage easement.
Storm sewers shall be made of reinforced concrete and have a minimum diameter of 15 inches and a minimum grade of 0.50%.
Manholes shall be placed at all changes in alignment and at all changes in grade.
Inlets may be substituted for manholes when approved by the Township Board of Supervisors.
Inlets (of the size and design specified by the Board of Supervisors) shall be constructed as required to intercept stormwater runoff along streets at intervals reasonably related to the extent and grade of the area to be drained.
In the design of storm sewer installations, special consideration shall be given to avoidance of problems which may arise from concentration of stormwater runoff over adjacent properties, including release or discharge of stormwater onto and across adjacent land when required.
Drainage plans shall be submitted for approval with preliminary plat or land development application and shall be approved by the Township Engineer.
If a public water supply is available or planned for the area, then provisions shall be made for its immediate and eventual use.
A water supply shall be in compliance with the rules and regulations of the authority supplying the water, subject to the approval of the Board of Supervisors.
Fire hydrants shall be established by the municipal authority having jurisdiction and installed as approved by the Board of Supervisors upon recommendation of the Township volunteer fire company and Township Engineer.

Same shall be of such size, length and material as approved by the Township Board of Supervisors.
Should the subdivider or applicant plan to provide trees, they are to be placed inside the recorded property lines.
In wooded areas or where other natural conditions exist in such a manner that their presence adds to the desirability of a subdivision or land development, the Board of Supervisors shall require that the subdivider or applicant preserve as much of the original stands of trees and natural conditions as is economically feasible and require that a minimum of grading be done other than the grading and excavating which is required in the construction of the improvements in accordance with the improvement standards included herein and approved by the Board of Supervisors.
At the time of submission of a subdivision for final approval, a grading plan shall be presented subject to and in accordance with the requirement of Chapter 88, Grading.
