Green Infrastructure Design Challenge

Overview

In April 2013, DC Water launched the Green Infrastructure Challenge, engaging firms to design innovative green practices that absorb rain water. These practices, known as Green Infrastructure, include installing green roofs (gardens on rooftops), rain gardens, rain barrels, using pervious pavements, removing impervious surfaces, and using other natural means to capture and infiltrate rain water. Capturing the water before it can enter the combined sewer system will aid in alleviating combined sewer overflows (CSOs) in the District.

Project Update

As part of its Green Infrastructure Challenge, DC Water has awarded over $2 million for construction of GI practices to be implemented on the 100 block of Kennedy Street NW under the Kennedy Street Revitalization Project, a partnership between DC Water, the District of Columbia Mayor's Office and the District Department of Transportation (DDOT). This project will manage stormwater to reduce combined sewer overflows (CSOs) into the District's waterways, improve traffic and safety conditions and contribute to the revitalization of the historic Kennedy Street NW corridor from Georgia Avenue to North Capitol Street within the Ward 4 neighborhoods of Brightwood and South Manor Park.

The GI practices implemented through this project will include bioretention (rain gardens), permeable parking lanes, permeable sidewalk pavers, landscape infiltration gaps, new street trees and stormwater related educational art.

On Friday, October 21, 2016, District of Columbia Mayor Muriel Bowser, Ward 4 Councilmember Brandon Todd, DC Water DC Clean Rivers Project Director Carlton Ray, District Department of Transportation Director  Leif Dormsjo, At-Large Councilmember Robert White Jr. and The Kennedy Street Revitalization Project Team kicked-off the Kennedy Street Revitalization Project, which is expected to be completed in the Fall of 2017. To learn more about this project, please visit www.KennedyStreetProject.com.

The Challenge will serve as a model to support DC Water's plan to implement Green Infrastructure in place of or in conjunction with "gray" engineering solutions, to capture rain water and prevent CSOs.

Green Infrastructure Phase II Awards

In March 2015, DC Water awarded contracts for final design to two selected firms: CH2M for the design of the Kansas Avenue Green Infrastructure Parks Project and Nitsch Engineering for the design of the Kennedy Street Green Infrastructure Streetscape Project. Concept plans were selected for final design award by a multi-agency evaluation panel for demonstrating innovative, cost effective, constructible, and replicable solutions to alleviating CSOs.
