U.S. Department of Agriculture (USDA) Natural Resources and Conservation Service (NRCS) Stormwater management at this beach parking lot controls the quantity and quality of the rain and stormwater that runs off the parking lot in Town Neck Beach, Sandwich, MA, on October 10, 2019. The grade of the parking lot brings water into common channels at the ends and intermediate points. It enters a cement basin/channel where the water slows over cement ridges, rocks, and sand layers. The slower cleaner water disperses into the tidal wetlands. The process helps keeps debris and sand from entering the wildlife and shellfish habitat.

Stormwater Runoff Control (NRCS Conservation Practice 570) provides control of quantity and quality of runoff caused by construction operations at development sites, and by other land-disturbing activities

The purpose of this practice is to regulate the rate and amount of water runoff and sediment from development sites during and after construction operations, to minimize flooding, erosion, and sedimentation. The practice is used when there is a need to compensate for increased peak discharges and erosion resulting from construction operations at development sites or other disturbed areas needing this conservation practice.
