Artificial turf shall be calculated as 100% impervious.

In the case of permeable pavers installed with layers of stone or aggregate underneath to allow stormwater to percolate through, and/or swimming pools, 50% of the area of such permeable pavers and/or the swimming pool shall be calculated toward the total impervious coverage of the lot.

Sand, soil and/or clean open stone that has not been compacted in such a way that may resist water infiltration or installed over an inhibiting liner, shall not count toward the total impervious coverage of the lot.

With regard to any proposed improvement, the applicant must submit for approval a drainage plan and all documentation deemed necessary to be approved by the Borough Engineer, based upon specific site conditions, as provided for in § 12-3 of the Ordinances of the Borough of Point Pleasant Beach.
