Contract No.: DCKA-2013-C-0160 CONSTRUCTION MANAGER S WEEKLY PROGRESS REPORT 8/3/2014 8/10/2014 Project Website: MacFarland-Allison St Underdrain installation Chevy Chase- Core sample #2, pervious concrete

2 EXECUTIVE SUMMARY Project Descriptions: The RiverSmart MacFarland project is along portions of Georgia Avenue, Allison Street, and Iowa Avenue and some of the nearby alleys. Work includes construction of facilities to reduce stormwater volume runoff. Work includes the construction of permeable paving and bioretention areas. Permeable paving in alleys, roads, and parking lanes provides on-site drainage and infiltration for storm water. Bioretention areas, also called rain gardens, in tree areas and curb bump-outs use landscaped planting areas to hold storm water and infiltrate into the soil. When constructed, the storm water flow will be monitored and measured to calculate the stormwater runoff reduction and evaluate its effectiveness for use in other neighborhoods. The RiverSmart Lafayette project covers areas along 33rd, Rittenhouse, Quesada, 32nd and Patterson Streets. Work includes construction of permeable paving and bioretention areas. Permeable paving in alleys, roads, and parking lanes provide on-site infiltration areas for storm water. Bioretention areas, also called rain gardens, in tree areas and curb bump-outs use landscaped plantings to hold storm water and infiltrate into the soil. The Green Alleys Chevy Chase project reconstructs the alleys between Rittenhouse St., Broad Branch Rd., 34th Place, 33rd Street and Quesada St. The entire alley will be constructed using full width pervious concrete, center strip of pervious concrete, and standard concrete. This project reduces the quantity of storm water runoff and improves the water quality prior to it entering the Districts storm sewer system. Proposed work will include but not be limited to: Bioretention areas, or rain gardens in tree box areas Permeable paving in alleys, roads, and parking lanes Curb bump-outs
