1043.01 DELINEATION OF FACILITIES UPON SUBMISSION OF PRELIMINARY PLAN.
All storm drains and drainage facilities such as pipes, gutters, inlets, catch basins, culverts and other proposed structures necessary for the collection, retention and conveyance of stormwater runoff shall be delineated, depicted and otherwise noted at the time of preliminary plan submission, under the Subdivision Regulations, as provided in this chapter. (Ord. 644. Passed 8-17-88.)
1043.02 PURPOSE OF FACILITIES.
(a) Suitable storm facilities shall be provided in order to maintain or lessen the existing rate of flow from the tract without damage to land or structures within and adjacent to the subdivision or land development.
(b) Storm sewers, culverts, bridges and related drainage installations shall be provided:
(1) To permit unimpeded flow of natural watercourses. Such flow may be redirected as required, subject to the approval of the Pennsylvania Department of Environmental Resources, the Army Corps of Engineers or any other applicable governmental agency.
(2) To insure adequate drainage of all low points as may be related to streets;
(3) To intercept stormwater runoff along streets, at intervals reasonably related to the extent and grade of the area drained, to prevent the flow of stormwater across intersections and to prevent the flooding of intersections during the design storm;
(4) To ensure the adequate and unimpeded flow of stormwater under driveways in, near or across natural watercourses or drainage swales. Properly sized pipes or other conduits shall be provided as necessary.
(5) To prevent excessive flow on or across streets, sidewalks, drives, parking areas and any other paved surface or accessway;
(6) To lead stormwater away from springs. (Ord. 644. Passed 8-17-88.)
1043.03 PLANS TO ACCOUNT FOR UPSTREAM AREAS; EVALUATION OF RUNOFF.
The stormwater management plan for each subdivision and/or land development shall take into account and provide for upstream areas within the entire watershed in computing discharge, sizing of pipes, inlets and other structures. The runoff from any proposed development shall be subject to evaluation, which includes the anticipated runoff from other existing or proposed developments within the same watershed. (Ord. 644. Passed 8-17-88.)
1043.04 MAINTENANCE OF NATURAL STREAMS, ETC.
All natural streams, channels, swales, drainage systems and/or areas of concentration of surface water shall be maintained in their existing condition unless alteration is approved by the Township and all other required governmental agencies. In any event, all encroachment activities and drainage facilities for drainage areas in excess of one-half square mile or (320) acres shall conform to the most current requirements of, and be approved by, the Pennsylvania Department of Environmental Resources, Division of Dams and Encroachments. (Ord. 644. Passed 8-17-88.)
1043.05 DRAINAGE FACILITIES CROSSING STATE ROADS.
Any drainage facility crossing a State road shall conform to all applicable Pennsylvania Department of Transportation design standards. (Ord. 644. Passed 8-17-88.)
