8-3A-5: RUNOFF, EROSION AND SEDIMENTATION CONTROL: This performance standard is substantially revised and supplemented by a detailed definition in chapter 1 of this title.A. A professionally prepared runoff, erosion and sedimentation control plan which will completely fulfill its purpose shall be implemented by:1. All developments in the lake village zoning district within one hundred fifty feet (150') of a lakeshore, wetlands or stream corridor; and2. Developments in other zoning districts that: a) disturb, or may reasonably be expected to result in the disturbance of, a cumulative total of more than one acre of land with a slope greater than eight percent (8%), or with a high erosion hazard; b) include one thousand (1,000) or more linear feet of road crossing a slope greater than eight percent (8%), or with a high erosion hazard; or c) create a cumulative total of more than ten thousand (10,000) contiguous square feet of impervious coverage.B. The purpose of the runoff, erosion and sedimentation control plan shall be to:1. Minimize land disturbance and maximize the retention of existing vegetation;2. Minimize the area disturbed by construction at any one time, protect vegetation that is to be retained from damage by construction activities, and temporarily control erosion from areas disturbed during construction;3. Promptly, permanently stabilize all areas disturbed, using revegetation or structural techniques (vegetative techniques are encouraged: see subsection D of this section);4. Minimize runoff velocities and prepare on site drainageways to handle the accelerated rate and increased volume of runoff without increasing channel erosion;5. Retain the additional volume of runoff generated by development on site until it can be evaporated, absorbed through an adequate filtering layer of vegetation and soil and/or released at a rate that does not exceed the predevelopment rate of release or the capacity of downstream drainageways to accommodate flow without increasing channel erosion, whichever is less;6. Protect water quality using detention basins, filter strips and similar techniques;7. This performance standard also provides for the future maintenance of runoff, erosion and sedimentation control measures (including earthwork, plantings and structures), as required by section 8-4-8 of this title. The commission may, with the advice of the DEQ, require a development to institute a program of monitoring the performance of its runoff, erosion and sedimentation control measures; and8. Runoff, erosion and sedimentation control plans, and the design, construction, installation, planting and maintenance of the measures they propose, shall generally follow the BMPs (best management practices) of the department of environmental quality, except that sizing of any grassed infiltration areas to provide for the infiltration of the first one-half inch ( 1 / 2 ") runoff from all impervious surfaces on the site shall be expanded to one inch (1").C. The use of dry wells, injection wells and similar techniques for runoff control shall be minimized.D. The use of vegetative, as opposed to structural, runoff control and soil stabilization techniques shall be encouraged. Vegetated runoff control areas (detention basins, filter strips, etc.) may be integrated into landscaped buffers required by section 8-3B-6 of this chapter. (Ord. 149, 10-22-2008)
