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.

How recently did it rain: Within the last hour
How heavy was that rain: Light Shower
Is anything preventing water from flowing into the system (e.g., debris, trash, vegetation): Partially
Is there standing water in the system: Yes
Notes/Comments:
Biggest issue is water bypassing the curb cut and flowing down Maple ave.
A bit of leaves clogging the system, though probably wouldn’t be enough to block a heavier flow if it had been raining harder. Only a bit of standing water in the basin.

Is there standing water in the system: Yes
Notes/Comments:
Lots of fall leaves this time of year. The system seems to be receiving a lot of water, but there was significantly more in the pre-treatment area than the treatment area. We were towards the beginning of the storm, so this could be the reason, but it did seem water was ponding in the pre-treatment area while the treatment was almost dry.
