EROSION AND SILTATION CONTROL POLICY
Resolution No. 81-276
April 27, 1981 (Supersedes Res. No. 77-163, March 28, 1977)
1. Findings and Declaration of Policy
The City Council finds that erosion continues to be a serious problem and
that rapid changes in land use from agricultural and rural to non-agricul-
tural and urbanizing uses, construction of housing, industrial -commercial
development, streets, highways, recreation areas, schools, public utilities
and facilities, and other land -disturbing activities have accelerated the
process of soil ero Sion and sediment deposition. The control and manage-
ment of surface runoff and erosion and sedimentation benefits both the
developer and the public.
2. Erosion and Sediment Control Plan
For the purpose of a'1e.:atirg harmful or damaging effects of on-site ero-
sion and siltation on r:eighbcring downhill or downstream lands and waters
in the City of Plymouth and adjacent communities during and after develop-
ment adequate controls of erosion and sedimentation of both a temporary and
permanent nature shall be provided by the developer during all phases of
land -disturbing activities. Plans and specifications for such controls
shall be submitted to and approved by the City Engineer. Said plans and
specifications will be a part of the development contract and compliance
will be assured by the development bond. No development shall be permitted
until said plan is approved by the City Engineer.
3. Required Control Measures
The following control measures are required for an erosion and sediment
control plan:
a. The plan shall be suited to the topography and soils so as to create the
least erosion potential.
b. The land shall be developed in increments of workable size on which ade-
quate controls of erosion and siltation can be provided and maintained
during the construction period. Operation shall be staged so that the
area being developed is not exposed for long periods of time without
stabilization.
c. Temporary vegetation and/or mulching shall be used to protect the areas
exposed during the development. No area shall be left denuded for a
period 'longer than 5 days on critical erosion areas from initial grading.
Such pericd may be extended if satisfactory control measures are estab-
lished and remain in place. This determination will be made by the City
Engineer.

d. Sediment basins (debris basins, desilting basins, or silt traps) shall
�^ be installed and maintained to remove sediment from runoff waters from
the land undergoing development. Storm sewer inlets shall be provided
with debris guards and microsilt basins to trap sediment and avoid pos-
sible damage from blockage. The silt shall be removed when necessary.
e. Permanent vegetation and structures shall be installed within 30 days
after completion of initial grading.
f. If the control measures required by items 3.a, 3.b, 3.c, 3.d and 3.e
are not installed or maintained by the developer, no additional build-
ing permits will be issued within the development until the necessary
measures are placed in control.
g. Erosion control practices shall follow the design criteria as shown in
U.S. Department of Agriculture Soil Conservation Services Urban Runoff,
Erosion and Sediment Control Handbooks.
