Best Ultra-Urban BMP in the Bay

This category recognizes the best application of green infrastructure (GI) practices that are built in highly urban areas to reduce flooding and pollutant delivery. Sites in this category will typically have more than 75% impervious cover.

Strong contenders in the category:

  1. Utilize an innovative design to achieve a high reduction of runoff and pollutants from the site
  2. Link green infrastructure practices together into an effective treatment train
  3. Create an attractive site, neighborhood or street amenity
  4. Effectively overcome the challenges encountered in the ultra-urban environment such as traffic, utilities and other underground infrastructure
  5. Contribute to one or more of the following:
    1. increased urban tree canopy
    2. building sustainability (e.g., energy savings, green building certification, etc.)
    3. easier and safer pedestrian movement
    4. public art

First Place

Kennedy Street Green Infrastructure Challenge

Project Team

Nitsch Engineering Team

D.C. Water and Sewer Authority

Tina Boyd & Associates

This innovative streetscape incorporated 33 green infrastructure facilities within one city block to provide three lines of defense: above ground rainfall capture through the enhanced tree canopy, at street level through a combination of landscape-based strategies, and permeable pavement, and below-grade infiltration using drywells. In addition to the stormwater treatment achieved by the project, the designers effectively incorporated education and placemaking elements such public artwork highlighting the water bodies the project was designed to protect.

McCormick Taylor

Flyway Excavating, Inc.

The Charlotte Street Conversion utilized porous pavers in 11 parking areas, 20 bio-retention areas in vegetated curb-extensions, and 12 subsurface storage beds to capture approximately 3.4 million gallons of stormwater from the adjacent streets annually. This street makeover also significantly improves pedestrian access an safety, and provides increased economic visibility for businesses. The project’s scale and attention to providing community amenities from safety to tree canopy expansion stood out to the jurors.

Project Team

Design Green LLC

District Department of Energy and Environment

Golden Triangle Business Improvement District

This integrated system uses a complete treatment train approach with permeable pavers, bioretention and a rainwater harvesting system to create a closed loop, self-sustaining green site. The project excelled in its community engagement, using interpretive signage and the development of a mobile app where users can find curated facts on the park’s green infrastructure elements, and take a self-guided walking tour. The park now serves as a well-utilized public gathering space for community members.

This schoolyard retrofit project — featuring rooftop disconnections, permeable pavement and a rain garden — receives an honorable mention for its outstanding use of public art in a stormwater BMP. The cloud sculpture design on the rainwater harvesting system was visually stunning while effectively drawing attention to the purpose of the project. The jurors also commend the project for its meaningful engagement with students throughout the design and implementation of the project.
