(A) Definitions. For the purpose of this section, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
EROSION CONTROL PLAN. A plan containing a list of best management practices to be applied during construction to control and limit soil erosion.
LAND DEVELOPMENT. Refers to any human-induced change to improved or unimproved real estate including, but not limited to, construction, installation, or expansion of a building or other structure, land division, drilling, site alteration such as that due to land surface mining, dredging, grading, construction of earthen berms, paving, improvements for use as parking or storage, excavation, or clearing.
PUBLIC WORKS PROJECT. Any land development conducted or financed by a local, state, or federal governmental body.
(Prior Code, § 9.805)
(B) Erosion Control Plan.
(1) The following divisions shall apply to any new land development within the city, except those developments with application dates prior to January 1, 1990. The application date shall be the date on which a complete application for development approval is received by the city in accordance with the regulations of the city.
(2) For land development, no preliminary plat, site plan, permit, or public works project shall be approved by the city unless the conditions of the plat permit or plan approval includes an Erosion Control Plan containing methods and/or interim facilities to be constructed or used concurrently with land development and to be operated during construction to control the discharge of sediment in the stormwater runoff.
(3) The Erosion Control Plan shall utilize:
(a) Protection techniques to control soil erosion and sediment transport to less than one ton per acre per year as calculated using the soil conservation service universal soil loss equation or other equivalent methods. The Erosion Control Plan shall include temporary sedimentation basins when, because of steep slopes or other sites specific considerations, other on-site sediment control methods will not likely keep the sediment transport to less than one ton per acre per year. The city may establish additional requirements for meeting an equivalent degree of control. Any sediment basins constructed shall be sized using one and one-half feet minimum sediment storage depths plus two feet storage depth above for a settlement zone. The storage capacity of the basin shall be sized to store all of the sediment that is likely to be transported and collected during construction while the erosion potential exists. When the erosion potential has been removed, the sediment basin, or other sediment facilities, can be removed and the site restored as per the final site plan. All sediment basins shall be constructed with an emergency overflow to prevent erosion or failure of the containment dike; or
(b) A soil erosion matrix derived from and consistent with the universal soil loss equation approved by the city.
