(A)
All subdivisions shall be designed and improved to provide for proper
grading and erosion control, including the prevention of sedimentation
or damage of off-site property. All subdivisions shall follow Chapters
18 and 33 and Appendix Chapter 33 of the Uniform Building Code, the
grading objectives indicated in the subdivision design guide, the
following design objectives, and any future grading ordinances or
policies adopted by the City:
(1)
Grading shall maintain or create a natural appearance to the extent
it is reasonable and feasible to accomplish.
(2)
The finished lot grading shall provide a building site and yard area
compatible with the surrounding pattern of development.
(3)
Erosion control measures shall be provided in accordance with the
provisions of the Uniform Building Code to prevent sedimentation or
damage to on-site and off-site property.
(B)
The following principles for controlling erosion and sediment shall
also be incorporated into subdivision design and improvements unless
it is determined by the Building Official that these principles are
not applicable to the particular project in question:
(1)
Minimize soil exposure during the rainy season by proper timing of
grading and construction;
(2)
Retain natural vegetation whenever feasible;
(3)
Vegetate and mulch denuded areas to protect them from winter rains;
(4)
Divert runoff away from steep denuded slopes or other critical areas
with barriers or ditches;
(5)
Minimize length and steepness of slopes by benching, terracing or
constructing diversion structures;
(6)
Prepare drainageways to handle concentrated or increased runoff from
disturbed areas by using riprap or other lining materials;
(7)
Trap sediment laden runoff in basins to allow soil particles to settle
out before flows are released to receiving waters;
(8)
Inspect sites frequently to ensure control measures are working properly
and correct problems as needed.
