Bethesda Police Department meets LEED® Silver Requirements

One of the main reasons the green roof was included in the design of the building was to reduce the stormwater runoff from the roof and protect local watersheds. The vegetated roof also helps increase the lifespan of the roofing membrane and keeps the building, and surrounding area, cooler on hot days.

The new 2nd District Police Station in downtown Bethesda is a unique public/private state-of-the-art police station designed to meet LEED® Silver certification requirements. It includes community space as well as a separate, secure entrance for police officers. The installation of the StormCapTM vegetated system with 1,000 plant plugs helps StonebridgeCarras developers meet the Montgomery County, MD Green Building and Sustainability Standards and Energy Guidelines.

StormCap pre vegetated roof systemThe high performing, low maintenance, StormCapTM system was selected for its superior water retention-to-weight ratio and excellent stormwater retention capability. The sedum blanket is delivered with 85% foliar coverage and provides an instant green cover. It consists of 10-12 species of sedum selected for their heat/drought tolerance and year-round visual interests. The sedum blanket helps reduce water evaporation, soil erosion and weed growth.

The Needled Mineral Hydro Blanket by UrbanscapeTM acts as a water reservoir to support plant health, and offers reliable stormwater management over the lifespan of the vegetated roof. Capturing up to 2.6″ (1.6 gal/ft2) of rainfall on the rooftop helps prevent stormwater pollution and protect local watersheds. The green roof has no permanent irrigation.
