Huntington Levee

Project Update: July 24, 2018

The project, still under construction, has weathered the recent storms well with some street flooding, but residents haven't experienced any structural flooding. The open channels, the basin (low area on the residential side of the levee), as well as the contractor’s temporary pumps have functioned well. We are continuing to monitor the weather and Cameron Run.

The levee will run parallel to Cameron Run. The purpose of a constructed levee is to minimize flooding, however street flooding may still occur during extreme events.

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).

Project Complexities

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

Project Timeline

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, Conceptual Design
  • Project Design Phase II (January 2014 - Winter 2017) - Completed
    • Schematic Design, Design Development, Construction Documents, Permitting, Land Acquisition, Bidding
  • Construction (Winter 2017 - Spring 2019)

Project Update: July 5, 2018

The exterior of the pump station is nearing completion and crews are working on interior and mechanical systems. The concrete I-wall installation has started and will continue for the next month. Improvements at the north end of Fenwick Dr. and Mount Vernon Dr. are ongoing.

Project Update: May 24, 2018

Recent wet weather has had minimal impact on construction and work continues on schedule. Masonry work at the pump station is nearing completion and the roof is being closed in. Approximately 75% of the sheet piling and embankment material has been installed. Utility work for the pump station has started. The overhead power line relocation and sanitary sewer work at the east end of the site are complete. Storm drain and road work at the north end of Fenwick Drive has started.

Project Update: March 23, 2018

An update on construction of the levee system will be presented at a community meeting on Wednesday, June 6, 2018, at 6:30 p.m., at the Huntington Community Center located at 5751 Liberty Drive, Alexandria.

Project Update: March 9, 2018

The relocation of the 15-inch sanitary sewer at the east end of the site is complete. Installation of the double box culvert at Fenwick Drive is complete and the contractor is backfilling around it. Structural steel work on the pump station is complete. The mechanical bar screens are installed. The pump station outfall structure and channel are complete. The pump around for the 48-inch sanitary sewer began March 5, 2018. The contractor will be working on this pipe for approximately three weeks.

Project Update: Jan. 29, 2018

The concrete for the pump station wet wells and top slabs are complete and the contractor has started assembling the steel for the pump station building. Relocation of the sanitary sewer at the east end of the site is almost complete. The sheet piling for the levee I-wall is being installed from the pump station west toward Fenwick Drive. The site has been prepped to begin installation of the double box culverts at the end of Fenwick Drive.

Project Update: Dec. 6, 2017

The project is nearly 50 percent complete. The wet well walls for the pump station are finished and have been backfilled. Form work for the elevated slab over the wet wells is nearing completion. Placement of concrete for the outlet structure at the pump station is almost complete. Installation of the 48-inch storm sewer through the site continues. The contractor has started placing fill for the levee embankment west of the pump station.

Project Update: Oct. 18, 2017

Concrete placement for the walls of the pump station is almost complete. The contractor has started the installation of the storm sewers and box culverts that connect to the pump stations. The concrete placement for the pump station outfall channel is 50 percent complete. Relocation of sanitary sewer at the east end of the site should begin soon.

Project Update: Aug. 28, 2017

Recent storms and flooding have not impacted construction at the levee site. The contractor is continuing to place concrete for the walls at the pump station. Installation of the toe drain and keyway excavation have begun.

Project Update: July 19, 2017

Construction of the pump station continues. Concrete placement will continue into August. The contractor has started installing the 48-inch storm sewer line near Fenwick Drive. This work is expected to take a couple weeks.

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.
