FINAL DRAFT 02 -23 -2011 (e) The City may require additional erosion and sediment control measures on areas with a continuous slope leading to a sensitive, impaired or special water body, stream, ditch or wetland to assure retention of sediment on site. (f) The plan must include conditions adequate to protect facilities to be used for post - construction stormwater infiltration. (g) The plan must include conditions to minimize off -site sediment transport on trucks and equipment. (h) The plan must minimize work in and adjacent to water bodies and wetlands. (i) Stable slopes shall be maintained throughout the construction process. (j) Steep slopes and the need for high cuts and fills shall be avoided (no slopes greater than 3(h):1(v), except as approved by the City engineer). (k) Protection shall be provided to minimize disturbance to surrounding soils, root systems and trunks of trees adjacent to site activity that are intended to be left standing. (1) Compaction of site soils shall be minimized. (m) Using and maintaining temporary and permanent soil stabilization. (n) All imported materials shall be approved by the City Engineer prior to placement on the site. (o) Appropriate on -site containment must be provided for all trash, solid waste, construction debris, floating debris, and hazardous materials. Disposal of collected sediment shall be deposited only in approved locations. (4) Construction Activity Requirements. Any activity subject to a permit under this ordinance must conform to the standards of the NPDES general permit regarding construction -site erosion and sediment control. (5) Final Stabilization. (a) Erosion and sediment control measures must be maintained until final vegetation and ground cover is established to a density of 70 %. (b) All temporary erosion and sediment control BMPs will be removed after all disturbed areas have been permanently stabilized. 1011.09 STORMWATER MANAGEMENT REQUIREMENTS 10 • •
