Site Description: This site is located on the northern end of the east parking lot of the ALCO office park on Valley Street. This site is as an infiltration basin, which is a low grassy depression that collects stormwater during rain events. Stormwater enters the site when parking lot and roadway runoff flow into the basin. Inside the basin, the soil and grass act as a filtering mechanism to remove pollutants from the stormwater. When the basin reaches full capacity, excess stormwater drains through an overflow structure. The captured stormwater should absorb into the soil within 24-48 hours after a rainstorm.
Photo-Video Tips: Stand near the southern edge of the west parking lot to capture video of stormwater flowing through the grassy slope and into the basin. Also, capture video of the stormwater accumulating in the basin and draining properly.

Notes/Comments:
Very minimal water entering this site based on the amount of rain falling. Maybe it’s just draining quickly? Or is bypassing somewhere?
