The subdivider shall construct and install drainage and erosion control systems. All systems shall be designed for runoff calculated for a 100-year storm event for detention basins and a ten-year event for all other facilities and conform to the county’s standards and specifications. A maximum stormwater-controlled release rate of two-tenths cubic feet per second per acre shall be the maximum permitted. However, no discharge shall exceed demonstrated historical flows from any drainage or sum of drainages. Further reductions in release rates may be required in situations of insufficient stormwater system capacity. The subdivider shall provide easements for storm drainage, natural watercourses or channels, streams, creeks, irrigation ditches or floodplains that intersect, traverse or are within the subdivision. The subdivider shall also dedicate easements for any pipe, conduit, channel and retention or detention areas as required by the County Engineer.
