Oregon Avenue and Bingham Drive, NW Sewer Rehabilitation Project
Greetings DC Water Community Stakeholders:
We know that you have received a number of updates on our Oregon Avenue and Bingham Drive, NW Sewer Rehabilitation Project since we started the work back in December 2016, and are anxious to see the close of this seemingly never-ending project. As we have been receiving a number of inquiries from interested and concerned residents in recent weeks regarding the status of the work, we thought it timely to provide you with the latest update. Please read below.
Many of you already know that our project is 90 percent complete. The only remaining work is permanent restoration of Bingham Drive, and per our last update provided during the October 28, 2019 monthly meeting of ANC 3/4G, our plan was to complete restoration of this roadway in early Spring 2020. Since that time, the National Park Service (NPS) and District Department of Energy and Environment (DOEE) have both become increasingly concerned about the need for additional stormwater management measures to be implemented on Bingham Drive prior to its restoration. This raised concern is largely due to heavy rainstorm damage to Bingham Drive which occurred during August 2018. As a direct result of this concern, our restoration plan is still pending approval by both agencies. We are currently working to resolve these concerns, and we have been meeting with both agencies to see what may be done so that we may move forward with our long-awaited restoration work.
After our most recent meeting with NPS and DOEE, we feel that we may have finally reached some resolution to successfully obtain our approvals! Once we have been cleared to proceed, we will be able to provide you a more realistic timeline for completion. This does, unfortunately, mean that the restoration of Bingham Drive will be slightly delayed once more and will not take place in early Spring 2020, as we’d planned.
We sincerely apologize for this delayed inconvenience, and we thank you for working with us throughout this much-needed project. Rest assured-once we are done on Bingham Drive, it will be a smooth, fully restored roadway from curb-to-curb and in some instances, will be in better condition that it was before our project began!
Thanks again, and please stay tuned for further updates!
DC Water is performing sewer rehabilitation projects throughout the city as part of its Capital Improvement Program. This project involves the rehabilitation of sewers on Oregon Avenue, NW from Beech Street, NW to Bingham Drive, NW and on Bingham Drive, NW from Nebraska Avenue, NW to Beach Drive, NW. DC Water is responsible for four sanitary sewer interceptors that cross the western half of Rock Creek Park owned by the National Park Service (NPS).
- The sewers along Oregon Avenue, NW drain into one of four sewers that cross the western half of Rock Creek Park, conveying flow from Oregon Avenue, NW to the Rock Creek Main Interceptor (RCMI).
- Three of these park crossings are in natural stream channels and are subject to erosion; two of those crossings are severely exposed and require abandonment.
- The fourth sewer is within the paved area of Bingham, Drive NW.
The objective of this project is to design and build a replacement sewer interceptor through the park to allow the abandonment the deteriorated interceptor. To better facilitate future maintenance and access the NPS allowed the sewer to remain through the only paved roadway in the area – Bingham Drive, NW. Benefits of this project include the rehabilitation of an aging sewer system, improving structural integrity while maintaining adequate hydraulic capacity, and reducing stream and groundwater infiltration and sanitary sewer overflows.
SCOPE OF WORK
- Construction of approximately 2,100 feet of new trunk sewer along Oregon Avenue, NW to redirect the flows to Bingham Drive, NW and abandoning the three park crossing sewers in or adjacent to streams.
- Construction of approximately 2,300 feet of new trunk sewer along Bingham Drive, NW to convey the flows from Oregon Avenue, NW to the RCMI.
- Replacing the old Creekbed sewer interceptor.
- Construction of new sewer manholes along Oregon Avenue, NW and Bingham Drive, NW.
- Construction start: December 2016
- Construction completion: November 2018
