Beginning on/around early August, installation of the wet well near the AGU plaza/prow will require sidewalk closures on Florida Avenue and 20th Street. The original plan was to install a pipe connection to the culvert, but due to DC Water’s requirements, a manhole was added to the scope resulting in a larger excavation than what was previously anticipated. The wet well work is related to the municipal sewer heat exchange system, a key energy recovery best practice required in the design of this project to achieve net zero. When complete, the sewer heat exchange will recover thermal energy from wastewater running through the sewer line beneath Florida Avenue.
To keep the community informed, please be aware of the following details of the work and related sidewalk closures:
- The community will see sidewalk closures on the AGU side of Florida Avenue and partial sidewalk closures on 20th Street beginning on/around early August for approximately five (5) months.
- Due to sidewalk closures, pedestrians will need to safely cross Florida Avenue at the crosswalk where it intersects with Connecticut Avenue to access the sidewalk on the other side of the street.
- Fencing will be placed on the side of the building along 20th Street, leaving a 6-foot wide walkway from the edge of the fencing to the tree pits along 20th Street for pedestrian use. This is a safety measure for pedestrians walking along 20th Street while work is happening near the prow/plaza area.
- Every business along Florida Avenue and 20th Street will still be accessible and will be open for business.
During the time that the sidewalk along Florida Avenue is closed, a tower crane will be placed within the sidewalk closure. The tower crane is needed to install the structural steel that supports the solar photovoltaic (PV) array – another key component in achieving net zero, and will be used for about four (4) months while that work is being completed. During erection and dismantling of the crane, there will be disruption to traffic on Florida Avenue in August and December.
Throughout this process we have worked with the Advisory Neighborhood Commission 2B (ANC 2B) to share updates, and will continue to keep them and the community informed as construction progresses.
Our priority throughout construction is to be a good neighbor. If you have questions, please contact firstname.lastname@example.org.
