Descriptions of the four citywide CWC-funded projects follow:

  1. Green Infrastructure Enhancements and Impervious Surface Removal – This project supports the District’s Urban Forestry Division’s program to maximize the water quality benefits provided by street trees in the District by installing new tree boxes, planting trees in empty tree boxes, and protecting mature trees by replacing their impervious surroundings with pervious asphalt that allows rainwater infiltration to tree roots.
  2. Large Parcel Canopy Tree Planting – This project helps the District meet its 40% tree canopy goal by planting large canopy trees on District properties that can support dense plantings.
  3. RiverSmart Homes Program (supplementary funding) – This program provides homeowners with rebates to install their own trees, rain barrels, or rain gardens or remove impervious surfaces from their property and replace it with permeable pavers and/or vegetation to promote the infiltration of stormwater.
  4. Citywide sewer rehabilitations – This project rehabilitated sewer mains in key locations throughout the District.
