{Tidal Potomac Fly Rodders} Four Mile Run - Flood Management

It looks like they will be dredging 4MR in late summer or early fall.  I'm newer to the area, but are efforts like this the extent of solutions to combat flooding?   Also since this isn't the first dredging they have done at 4MR, what are the general wildlife impacts (fishing and otherwise) that you have seen?

Four Mile Run flood channel maintenance agreement 

The County Board approved an intergovernmental agreement with the City of Alexandria for the two jurisdictions to share maintenance costs and the dredging of the two-mile Four Mile Run flood channel, which extends from Shirlington to the Potomac River.  The channel straddles the boundary between the County and the City of Alexandria.

Maintenance of the open channel includes clearing debris, sediment and vegetation, and re-stabilizing stream banks as required by the United States Army Corps of Engineers (USACE) annual inspection program. The two jurisdictions have agreed to a 50-50 split of the costs of the dredging, which will help preserve the flood channel's capacity and reduce flood risk in neighborhoods surrounding South Four Mile Run.

The work will begin in late summer or early Fall, 2021 and take approximately four months. The Four Mile Run Levee System, a USACE flood risk management project, was completed in 1984 in response to several devastating floods in South Arlington. The Board voted unanimously to approve the agreement. To view the staff report, scroll to Item No. 26 on the agenda for the Saturday, March 20, 2021, County Board Meeting agenda.
