A.
Engineered grading plans for single-family homes and private road
developments shall be submitted by the proprietor.
B.
Engineered grading plans shall be prepared by any of the following
registered professionals, alone or in combination: civil engineer,
land surveyor, architect, and/or landscape architect.
C.
The engineered grading plan shall include the following information:
(1)
The legal property description.
(2)
The bench marks used.
(3)
Existing grades on a fifty-foot cross section to a minimum of 50
feet beyond the site property line and sufficient intermediate grades
to determine such things as ditches, swales, adjacent pavement, buildings
and other pertinent features.
(4)
All existing topography.
(5)
Location of any watercourses, wetlands, lakes and ponds on the site.
(6)
Off-site topography, adjacent building grades, paved parking areas
or drives (indicate direction of drainage), drains, culverts and other
pertinent features. Show typical cross sections of existing drains
or swales.
(7)
Existing easements.
(8)
Existing utilities (size, depth, location), manholes (rim and inverts),
and culverts.
(9)
Street rights-of-way, existing and proposed.
(10)
Proposed topography of the site.
(11)
Location and description of any proposed stormwater management
and erosion control measures.
(12)
Flow direction of stormwater runoff from the site before and
after development, including the direction of overland flow.
(13)
Proposed elevations should be underlined or boxed in to differentiate
from existing elevations. It is expected that all hard surface elevations,
such as foundation tops, pavement, and structures be in hundredths
of a foot and all ground elevations be in tenths of a foot.
(14)
A location map.
A.
The Township Engineer shall review engineered grading plans to ensure
compliance with the following standards:
(1)
Cutting, filling and grading shall be minimized and the natural topography
of the site shall be preserved to the maximum possible extent.
(2)
Sediment caused by accelerated soil erosion shall be trapped and
retained on the site through the use of effective soil erosion control
measures.
(3)
Seeding, mulching, establishment of a vegetative cover, or other
permanent soil erosion control measures for all disturbed land areas
shall be completed within 15 calendar days after final grading or
the final earth change has been completed.
(4)
When it is not possible to permanently stabilize a disturbed area
after an earth change has been completed or where significant earth
change activity ceases, temporary soil erosion control measures shall
be implemented within 30 calendar days. All temporary soil erosion
control measures shall be maintained until permanent soil erosion
control measures are implemented.
(5)
Through the design of site contours, yards, paved areas, roadways,
and driveways, the on-site infiltration and detention of stormwater
runoff shall be reasonably required when determined to be necessary.
(6)
Diversions of stormwater runoff to adjacent properties which increase
the volume, rate of discharge, or pollutants carried by stormwater
shall be prohibited.
B.
Engineered grading plans shall be reviewed and approved by the Township
Engineer prior to the issuance of a building permit.
