Site Description: This infiltration basin is located at the intersection of Maple Ave and Cladrastis Ave in Roger Williams Park. It is a low grassy depression that fills with stormwater during rain events. Stormwater enters the site through two separate cuts in the curb within the bike lane on Maple Ave. Two permeable paver areas are designed to collect sediment and debris. From the paver areas, water will flow into a single grassy basin. Inside the basin, the soil and grass act as a filtering mechanism to clean pollutants from the stormwater. When the basin reaches full capacity, excess stormwater drains through the overflow structure located within the basin. The captured stormwater should absorb into the soil within 24-48 hours after a rainstorm.
Photo-Video Tips: To capture whether stormwater is flowing through the curb cut opening and storm drain into the basin, stand in the bike lane. Also, verify with video whether stormwater is accumulating in the basin and draining properly.
