§ 8.3.1. General
Stormwater Management (SWM) ponds may be of two basic types: On-site/off-site and regional. In general, on-site or off-site ponds are those which are located off-channel and provide stormwater management for a particular project or development. Regional ponds are designed to provide stormwater management in conjunction with other improvements on a watershed-wide basis. SWM ponds may be further classified as retention or detention ponds and may incorporate water quality best management practices (BMPs) as defined in the Environmental Criteria Manual. The performance and safety criteria in this section apply to all ponds which provide management of peak rates of stormwater runoff regardless of type.
