RULE D EROSION AND SEDIMENT CONTROL PLANS 1. POLICY. It is the policy of the Board of Managers to prevent erosion of soil into surface water systems by requiring preparation and implementation of erosion and sediment control plans for land distt aece- disturbing activities. REGULATION. A and required for new dev°lopment redevel •- - - - -- - 2. REGULATION. An erosion and sediment control plan must be submitted, and a permit received from the District, for (a) the grading, excavation, filling or stockpiling of more than fifty (50) cubic yards of earth or other erodible material; or (b) surface soil disturbance or removal of vegetative cover on five thousand (5,000) square feet or more of land. This requirement does not apply to plowing as part of an ongoing farming operation, 3. DESIGN CRITERIA FOR EROSION CONTROL PLANS. Erosion and Sediment Control Plans must comply with the following criteria: (a) Natural site topography and soil conditions must be consideredspecifically addressed to reduce erosion and sedimentation during construction and after project completion.

REQUIRED EXHIBITS. The following exhibits must accompany the permit application. One set, full size (22 inches by 34 inches); two sets, reduced to maximum size of 11'40 " inches by 17 inches. (a) An existing and proposed topographic map which clearly indicates all hydrologic features and areas where grading will expose soils to erosive conditions. The Plan must also indicate the direction of all site runoff. (b) Tabulation of the construction implementation schedule. DRAFT DOCUMENT 22 • • •
