In the space provided below, briefly summarize how the stormwater runoff will be treated. Runoff from the site will be treated by two different systems. The site will utilize pervious pavement within the front parking field to infiltrate stormwater from this area. The impervious areas of the building and remaining parkingJdrive areas will be conveyed to an infiltration basin on the east and south side of the site. 2. a.

Example #2 Project is a high density commercial site with a 5,000 square foot parking lot. Project is within 1/2 mile of and draining to SA waters. An infiltration system is proposed. The parking lot will handle <100 cars per day and is a flexible pavement with a 4" gravel base. Managed grass factor is 0.4. 5000 x 0.4 = 2000 square feet is counted as managed grass. 5000 - 2000 = 3,000 square is counted as impervious.
