Brief:
| This project consisted of three study sites, a control, traditional development and a BMP development. The control site was a 5.5 ha residential area with 43 lots (size ranges from 15,000-20,000 sq.ft.) that had 29% impervious area. The traditional development was a 2 ha site with 17 lots. This site used traditional building practices and a standard curb and gutter system. After construction there was 32% impervious area. The BMP site was 1.7ha with 12 units and 22% impervious area. They implemented various Best Management Practices both during and after construction to try to maintain the hydrologic conditions. Construction BMPs included seeding stockpiles to prevent loss, haybales, silt fences, earthen berms, and basement holes to retain stormwater onsite. Post-construction BMPs included a narrow paver road, clustered houses, deed restrictions, public education programs, grass bioretention swales, bioretention cul de sac, bioretention gardens in each lot, and crushed stone/paver shared driveways (in some cases).
