The following management practices shall be applied to all development and earthmoving activities.
(A) All development shall conform to the natural limitations presented by the topography and soil in order to create the best potential for preventing soil erosion.
(B) All required erosion and sedimentation control best management practices shall be installed prior to the start of any earthmoving activities.
(C) Best management practices for erosion control and sediment control shall be applied to each development/construction site.
(D) Development on slopes with grades greater than 12% shall be carefully reviewed to ensure that adequate measures have been taken to prevent erosion, sedimentation and structural damage.
(E) For phase construction erosion and sediment control measures shall be coordinated between separate stages of development.
(F) Final plant covering or permanent surface treatment shall be installed as soon as possible after completion of final grading.
(G) Land shall be developed in increments of workable size such that adequate erosion and siltation controls can be provided as construction progresses. The smallest practical area of lands shall be exposed at any one period of time and no exposure shall exceed 60 days unless extended by the Council.
(H) Where the topsoil is removed, sufficient arable soil shall be set aside for re-spreading over the developed area. The topsoil shall be restored to a depth of four inches and shall be of a quality at least equal to the soil quality prior to development.
(I) The natural drainage system shall be used, as far as feasible for storage and flow of runoff except that no stormwater drainage shall be discharged to marshlands, swamps or wetlands. Stormwater drainage shall be discharged to retention basins or other treatment facilities. Temporary storage areas or retention basins scattered throughout developed areas shall be encouraged to reduce peak flow, erosion damage and construction cost.
(J) Public and private properties adjacent to the development site shall be protected from the effects of sedimentation. Any violations of this provision must be corrected by the owner to the satisfaction of the city within five days of receiving notification of such. If the violation is not remedied within the time period specified, the city may correct the problem and assess the costs incurred to the property owner.
