B. Site
improvement plans shall consist of the following:
1. The site plan (single lot developments) or title page (subdivision
development).
2. Grading cross section and contour sheets. A grading
plan for the entire plat shall be provided. All grading details pertaining
to site development shall be shown in plan or cross section sheets.
The required information may be combined for presentation on one (1)
or more drawings or maps. The City Engineer may request that the information
be presented on drawings or maps in addition to those submitted in
the interest of clarity, speed and efficiency in the review process.
All grading plans submitted for approval must include, but are not
limited to, the following specific details as determined by the City
Engineer:
a. Existing and proposed contours, normally at two (2) foot intervals.
Contour intervals for grading plans other than the above will require
special approval.
b. Existing ground and finished grade for cross section sheets plotted
at scale of not less than one (1) inch equals one hundred (100) feet
horizontal and one (1) inch equals ten (10) feet vertical and of such
accuracy that the City Engineer can readily interpret the plan.
c. It shall show existing manmade features such as buildings, structures,
easements, high tension towers, pipe lines, existing utilities such
as water and sewer lines, etc., excavations, bridges, culverts and
drains and shall identify adjacent properties.
d. Site grading shall be compatible with ultimate roadway elevations.
e. Siltation control details shall be provided. The sediment control
plan should be implemented before grading begins. No graded area is
to remain bare without being seeded and mulched within a reasonable
period of time, approved by the City Engineer. Positive steps must
be exercised to prevent this soil from damaging adjacent property
and silting up all storm drainage systems whether on or off site.
f. Sinkholes affected by grading must be treated.
g. All low places, whether on or off site, should be graded to allow
drainage. This can be accomplished with temporary ditches.
3. Soil stabilization during construction. Prior to
issuance of a building permit for lot or site improvements including
streets and other public areas, the developer shall present the City
Engineer with a soil stabilization strategy documented in a form determined
by the City Engineer. The soil stabilization strategy shall address
the following issues:
a. Sites should be graded only in areas necessary to accommodate the
proposed construction and necessary and safe access to it. The stabilization
strategy should include a map of the site (preferably overlaid on
approved preliminary or record plat) so indicating areas of proposed
grading.
b. Graded areas shall be stabilized immediately upon grading and maintained
to prevent or minimize erosion until permanent prevention measures
are in place. Permissible techniques include contour furrowing or
other surface roughening techniques, seeding or installation of grass
sod.
c. Slope changes should be designed to keep the slope length and gradient
to a minimum, thus minimizing stormwater velocities of graded areas.
d. Measures shall be taken to direct stormwater from graded portions
of the site. This may be accomplished utilizing diversion berms or
ditches and/or sediment basins.
e. Sediment shall be retained on site by filtering runoff or providing
settling basins to allow soil particles to settle out.
f. Standards:
(1)
An average of five (5) tons of soil loss per acre per year shall
be deemed the maximum tolerable level of sediment leaving the site
during development. The universal soil loss equation shall be used
in predicting average soil loss.
(2)
The calculation of the above tolerable level of soil loss shall
be based on average anticipated losses during the year or years of
development and in a one (1) year period immediately following development.
4. Soil preservation, grading and seeding.
a. Soil preservation and final grading. No certificate
of occupancy shall be issued until final grading has been completed
in accordance with the approved record plat. Each lot shall be covered

thousand (20,000) square feet provided such grading is clearly incidental
to the improvement of the property and does not alter the drainage
or adjacent properties.
c. Grading by any public utility for the installation, inspection, repair
or replacement of any of its facilities.
d. Grading of property for or by any governmental agency in connection
with a public improvement or public work on said property.
e. Grading of land for farming, nurseries or gardening or similar agricultural
or horticultural use whenever there is substantial compliance with
recommendations or standards of the local soil conservation authority.
f. Grading activities in public right-of-way covered by an appropriate
excavation permit.
g. Grading activities in quarries and land fills.
h. Trench excavations covered by an appropriate construction permit.
