Site Description: This site is located in South Kingstown, near the southeaster end of Pettaquamscutt Cove of the Narrow River along Narragansett Ave E/Mumford Road. It can be found at the cross street of Kimberly Drive. Stormwater enters a series of depressions filled with large rock and grass called a bio retention trench through an entry point along the right side of Narragansett Ave East/Mumford Road. The first basin, filled with rock, is design to accumulate sand and sediment. To keep the basin working properly, it’s important to prevent sand and silt from accumulating in the grassy areas. If too much sediment builds up, the stormwater won’t be able to drain effectively, and the soil won’t be able to remove pollutants. The soil in the basin acts as a filter to clean the stormwater. If the basin reaches full capacity, excess stormwater is relieved through a storm drain at the end of the trench on Narragasnett Ave E/Mumford Rd. After a rainstorm, the stormwater captured in the series of basins should be absorbed into the soil within 24-48 hours.

Photo-Video Tips: To take photos or videos, stand near storm drain at the bottom of the system (see photo. Look upstream towards the top of the hill on Mumford Road and capture the stormwater flowing into and out of the bio retention basin. Additionally, you can capture footage of the stormwater in the bio retention basin itself. These shots will help confirm that the system is working as intended.
