On the afternoon of Wednesday, October 17th, engineers from the DDOT Bloomingdale Surface Water Management Project and I met to review conceptual designs for low-impact development (LID) features to mitigate flooding in and around the intersection at 1st Street and Rhode Island Avenue NW. The approximately $1m project includes the following proposed design features that will yield approximately 300,000 gallons of total system performance.
1. Permeable pavement and underground storage in the alley segment directly behind Mt Bethel Baptist Church
2. Permeable pavement and underground storage in the alley segment between Thomas and T Streets west of 1st Street
3. Rain garden and underground storage in the triangle park located at T Street and Rhode Island Avenue in front of the The Flatiron Condominium
4. Rain garden and underground storage in the triangle park located at T Street and Rhode Island Avenue in front of the Rustik Tavern
5. Underground storage beneath the median along the 100 Block of Rhode Island Avenue
6. Catch basin enhancements
7. Bio-retention cells on either side of Thomas Street near the intersection with 1st Street
DDOT will also coordinate with the DDOE rain barrel team to install rainwater harvesting systems in the triangle parks in front of The Flatiron and Rustik to facilitate the watering of plants in each park using captured storm water.
NspireGreen will lead a community meeting on Saturday, November 3rd, from 10am to noon, to present detailed designs and construction plans for the features listed above. Construction is scheduled to begin on November 16, 2012 and will continue for approximately 6 months.
Please let me know if you have any questions.
