Fairfax County is building a levee and pumping station to protect homes and other property in the Huntington neighborhood from flooding. Voters approved a $30 million stormwater bond in November 2012 to fund the construction of the levee and pumping station. This is a complicated project that has required review by local, state, and federal agencies. Completion is scheduled for spring 2019.
Project Update: June 2, 2017
Concrete placement for the pump station has begun and will continue through the month of June.
Project Update: May 2, 2017
Excavation for the pump station has begun. A crane is installing the piles that will hold wood lagging for temporary shoring around the excavation. A dewatering system has been installed to keep water out of the hole.
Project Update: April 20, 2017
Work is moving along well. Tree clearing and grinding operations are complete and top soil is being stockpiled on-site. The old water utility buildings have been removed and wells have been decommissioned. Installation of the dewatering system for the pump station excavation is underway and excavation is expected to begin toward the end of April. A crane that will be used to construct the pump station was delivered.
Project Update: March 13, 2017
The erosion and sediment controls have been installed and were approved by the site inspector last week. The contractor is nearing completion of site clearing and grubbing, and construction of the access road from Metroview Parkway continues. The security fence around the site is complete and will be extended from Fenwick to Metroview to keep people off the access road. Excavation for the pump station wet well is expected to begin in April. A groundbreaking ceremony will be held on Thursday, March 23, 2017, at 10 a.m.
Project Update: Feb. 23, 2017
The contractor has begun work on the construction access road from Metroview Parkway. Initial work includes the installation of the erosion and sediment controls and a pipe culvert over outfall #1. These steps are being taken to control stormwater runoff from the site and prevent sediment from entering Cameron Run. The construction access road will be extended across the site to the future pump station.
Project Update: Jan. 19, 2017
Two temporary trailers have been placed on-site to serve as offices for the contractor and engineering firm. For safety reasons, please stay away from the trailers. Safety fencing and signage will be erected soon closing access to the park. Erosion and sediment controls (black, cloth fencing) will be installed next. An access road will be built from Metroview Parkway on the eastern border of the site. Most construction vehicles will access the site via this entrance. Maps and renderings were presented at the Oct. 22, 2016 community meeting.
What to Expect During Construction
- Construction activities will be limited to 7 a.m. to 7 p.m., Monday through Friday.
- Any weekend and/or holiday work must first be approved by the county.
- Contractor parking is prohibited in the neighborhood.
- Truck traffic through the neighborhood will be restricted.
- Noise levels will comply with the Fairfax County Noise Ordinance.
The Huntington Park playground and surrounding green space is closed and will be secured with perimeter fencing. Improvements to Farrington Park playground are scheduled to begin in February and should be completed spring 2017. Once the levee project is completed in 2019, residents will have approximately 4,800 linear feet of recreational trails along the top of the levee and around the ponding area.

For after-hours storm flooding emergencies that are not life threatening, call 703-323-1211, TTY 703-239-8498, and state that you are reporting a storm sewer emergency. For sanitary sewer flooding, call 703-323-1211, TTY 703-239-8498. Report suspicious activities to the public safety non-emergency line at 703-691-2131, TTY 703-204-2264.
The Huntington community floods due to tidal surges from the Potomac River and flash flooding from the Cameron Run Watershed. The community was built prior to enactment of the current floodplain regulations.
Since 2002, three floods have damaged vehicles and other property in this neighborhood. There are 160 homes in the FEMA-designated floodplain that are at risk in the future.
While the levee can prevent flooding of houses from the types of storms that have happened in the past, it is not designed to offer protection from flooding that is caused by storms that are greater than a 100-year event (a storm that has a one percent chance of occurring in a given year).
A temporary fence will be erected along the perimeter of the site (yellow line) and remain in place until the completion of the project in 2019.
The design prepared by ARCADIS includes:
Levee - Earthen embankment and I-wall combination
- 2,800 feet long (beginning west of Fenwick Drive and running eastward to the Riverside apartments)
- 6 to 11-foot high earthen embankment (height is dependent upon the elevation of the existing ground along the alignment of the levee)
- 4-foot high concrete I-wall on top of the earthen embankment
- 13 feet wide at the top of the embankment including an 8-foot wide asphalt trail
- Average of 43 to 68 feet wide at the base, dependent upon the height of the levee
- Buried collection drain along the toe of the levee to control ground water seepage
- New storm drains to connect existing storm drains to the pump station
- Concrete box culverts and a vegetated swale will divert stormwater from the to the pumping station during large storm events
- Pumping station facility, located near the east end of the levee
While the levee can help mitigate flooding of houses from the types of storms that have happened in the past, it is not designed to offer protection from flooding that is caused by storms that are greater than a 100-year event (a storm that has a one percent chance of occurring in any given year).
The levee design has been a complex process that required:
- Permits from local, state and federal agencies (all permit requirements have been met)
- Environmental and other reviews by state and federal agencies
- Construction in a wetlands, which is regulated by state and federal agencies
- Acquisition of land and easements
- Relocation of existing utilities
The levee design and contract award were completed on schedule.
The county is proceeding on the following schedule:
Project Design Phase I (June 2013 – January
2014) - Completed
- Data Collection
- Site Study
Project Design Phase II (January 2014 - Winter 2017) -
- Schematic Design
- Design Development
- Construction Documents
- Land Acquisition
- Construction (Winter 2017 - Spring 2019)
