[Ord. No. 97-24 § 802Q]
a.
Prior to the issuance of a construction permit, including a construction permit for an in-ground swimming pool or outdoor tennis courts, and prior to the alteration of any site elevations in excess of one foot where a construction permit is not required, a lot grading plan shall be submitted to the Construction Official and approved by the Borough Engineer.
The lot grading plan shall be in duplicate, shall be prepared by a licensed professional engineer and shall show all information required in paragraph b below. Upon receipt of the site plan, the Borough Engineer shall review the plan and determine whether or not it meets the standards set forth in this chapter. Upon making such a determination, the Engineer shall retain one copy and forward one copy of the site plan to the Construction Official.
b.
The lot grading plan shall include the following information:
1.
Existing and proposed grades represented by contours at two foot intervals when grades are below 20%, at five foot intervals when grades are above 20% and by spot elevations when flatness of the plot makes the use of contours impractical. Existing contours shall be shown for a distance of 50 feet beyond the plot limits. This distance may be reduced if approved by the Borough Engineer.
2.
Existing and proposed elevations at all plot corners, building corners, centers of swales, tops and bases of walls, disposal bed corners and at the locations of all changes in direction of stormwater flow.
3.
Proposed elevations at changes in grade of driveways and walks, as well as the proposed and existing curb, sidewalk and road elevations at the plot corners.
4.
Swales and other means for the disposition of all stormwater runoff originating within the plot and of stormwater originating outside the plot and which will flow into the plot.
5.
Proposed buildings, including all overhangs, the number of stories and the proposed elevation of all floors, basements and cellars and the front and side setback distances.
6.
All proposed walls, walks, driveways, sidewalks and curbs, with widths shown.
7.
Type and width of existing pavement and width of the right-of-way on the road on which the plot fronts.
8.
Metes and bounds of all property lines, monumentation at all property corners and location of any existing fences, hedges, etc., along the property lines.
9.
Any proposed changes in grade shall not exceed a slope of three to one (3:1).
10.
Provide a diagram and calculations for the determination of building height. The calculations must include the grade elevations adjacent to the perimeter of the building foundation for the existing and proposed grade elevations and the highest point of the building.
