19 Figure 21j Beltsville Industrial Park - Candidate Stormwater Retrofit Project Beltsville Industrial Park Area bounded by Bacon Drive to the Site Location: north, the existing railroad track to the east, Tucker Drive to the south, and Ewing Road to the west, in Beltsville, MD. IC-M-01-S-10 ADC Map Book Location: 7 J 2 7 K 2 Map ID: 513 Approximate Associated 24 Drainage Area (acres): Approximate 90% 21.6 acres Imperviousness: The site consists of a large impervious industrial area with poor stormwater control, especially along Hanna Street and Tucker Street, where no storm drain network exists. The area drains east via surface flow into the Indian Creek. Underground Pipe Storage, Underground Sand Filters, LID Bioretention - Replace the abandoned railroad track with an oversized underground pipe storage system and control structure to control water quantity discharge, as well as storm filters for the proposed drainage inlets, and underground sand filters to provide water quality and sediment removal. Install bioretention systems, surface sand filters, tree box filters, and grass channels where feasible within the drainage areas. Project Description: The underground storage system consists of three interconnected pipes (3 projects). A downstream control structure with built-in weir/orifice controls the discharge flow. The system connects to an existing pipe discharging into the creek. The existing pipe and outfall will need to be upgraded to accommodate the increase in discharge flow. Each pipe system will have underground sand filters designed to provide water quality for the first one inch of rainfall. A total pipe length of approximately 4,400 linear feet (LF) can be installed (1,950 LF in Project 1, 1,800 LF in Project 2, and 650 LF in Project 3). The site topography and location of the outfall provide enough drop in elevation (138 feet to 104 feet) to install the underground storage pipe with adequate slope and cover. Within the drainage area, few places are available for installing LID systems. The locations of the proposed bioretention, sand filters, and grass channels are shown on the attached drawings. 148

The priority was determined by the property s geologic content, physical location, size, and ownership. High priority was given to properties that contained existing stream corridors, properties that are adjacent to streams or properties that are greater than five acres in size. Low priority was given to properties that were less than one acre in size, those owned by a private Homeowner s Association, or those owned by another public agency. All other properties were given medium priority. 3 This is an assessment criterion used in the above-mentioned report to determine the property s potential for acquisition. Low potential was given to properties located outside Prince George s County Green Infrastructure Plan, properties set aside for the Prince George s County Woodland Conservation and Tree Preservation Program, or properties where the owner has already declined to sell. 190
