For several months, David, Elizabeth, Pranith, Tadek, Shamiya, Kheya and Tapthi, who make up Team RORG (Run Off Rain Garden) have been researching, designing and implementing their project.
The two original sites were chosen because of they were in an appropriate spot for a rain garden and were cleared by Miss Utility for excavation. However, after boring multiple spots to test the soil, it was determined the soil was too rocky for a rain garden.
The benefits of the project are a significant amount of future run-off in the project area watershed will be captured by the hybrid rain garden where sediment and pollutants will be removed, and most of the water will have time to percolate into the ground rather than rushing the Horsepen Creek, causing additional erosion.
Three additional sites were chosen, all of which receive run-off from uphill areas. The three sites were cleared by Miss Utility and soil bore tests were performed. Due to the rockiness of the soil it was decided that a modification off the current design would be best. After additional research, a hybrid design featuring coconut fiber biologs as check dams was adopted.
Technical assistance and on-site consultation has been given by Mr. Daniel Schwartz, a soil scientist with the NoVa Soil & Water Conservation District, who has also arranged a survey of the current project site.
