Backlick Run Stream Bank Stabilization Phase II

The City of Alexandria awarded a contract to Environmental Quality Resources LLC, of Millersville, Maryland for the construction of Backlick Run stream embankment repairs. This project was divided into two distinct construction sites located at the east and west ends of the existing concrete channel. The work on the east site involved concrete repairs to the spillway along with rip-rap placement downstream and on the embankments.  The work on the west site involved replacement of the concrete embankment protection adjacent to Armistead Boothe Park. The purpose of the project was to prevent further erosion of the north bank and to restore the channel geometry to original conditions.

During Tropical Storm Lee, which occurred from September 5 through September 9, 2011, the City experienced severe flooding along Backlick Run. The flooding associated with that storm event caused severe erosion of the stream embankments.

Construction began in February 2015 and lasted for approximately 180 days.  Construction access to the east site was from Duke Street through Ben Brenman Park. Construction access to the west site was from Edsall Road through Armistead Boothe Park via the park access drive.

Charles Barrett Elementary School

The City of Alexandria employed the services of Sagres Construction Company for the construction of Stormwater Management improvements at Charles Barrett Elementary School.  This project worked to improve the water quality of stormwater runoff discharging into the City's storm sewer system.

This project included the construction of a bio-retention facility, a below-grade prefabricated filtration device, and storm pipe replacements.  Bio-retention is a process in which contaminants and sedimentation are removed from stormwater runoff.  The improvements provide filtration and mitigate the existing ponding condition in the area.  The bio-retention facility is landscaped, thereby increasing tree canopy coverage while reducing mowing requirements.  Furthermore, the bio-retention facility provides an added educational benefit to the school.

Burke Library Stormwater Management Improvements

The City of Alexandria employed the services of Sagres Construction Company for the construction of stormwater management improvements at the Burke Library. The purpose of the project was to improve the water quality of stormwater runoff discharging into the city storm sewer system.  

The intended improvements of the site included construction of a bio-retention facility and a below-grade prefabricated filtration device.  The improvements provided filtration of stormwater runoff in the area. The bio-retention facility was landscaped, thereby increasing tree canopy coverage while reducing mowing requirements. Additionally, minor changes were made to the parking lot so there will be no loss of parking spaces due to the addition of the stormwater management improvements. The construction was completed in May 2015.

Cameron Run Weir Repair

The City of Alexandria awarded a contract to Flippo Construction Company to perform repairs on Cameron Run Weirs #2, 3, 4 and 5. The weirs act as energy dissipaters to reduce flow velocity in the channel and minimize erosion. The purpose of this project was to repair damage caused by Tropical Storm Lee. This reach of Cameron Run is a flood control channel designed by the U.S. Army Corps of Engineers.

During Tropical Storm Lee, which occurred from September 5 through September 9, 2011, the City of Alexandria experienced severe flooding in Cameron Run. The severe flooding caused much of the rip-rap along the toe of Weirs #2, 3, 4 and 5 to be washed away. Due to erosion concerns from future flooding, the existing rip-rap (rock or stone used to prevent erosion) will be replaced and supplemented with larger rip-rap to provide added durability and stability. This project also included repair of the concrete energy dissipater at Weir #3 using cast-in-place concrete to prevent future scour and damage at the weir. The contractor provided measures to prevent sediment migration to areas downstream during construction. The construction was completed in January 2015.

City Marina Dredging 

The City of Alexandria awarded a construction contract to McLean Contracting Company to perform maintenance dredging of the City Marina.  The construction work was completed in January 2015.  All of the construction activities took place on the river, including staging and overnight storage of equipment, creating no landside impacts.  A floating turbidity curtain, used to control discharge of sediment, was placed and crews moved throughout the project area. The accumulation of natural and storm driven sediment routinely creates the need to dredge the Marina to maintain access and safe passage.  Dredging is necessary every five to six years on average, and was previously performed in 2002 and 2008.

2014 Completed Projects

Taylor Run Sanitary Sewer Upgrade and Stream Restoration Project

The City of Alexandria employed the services of Sagres Construction Company to construct sanitary sewer upgrade on Janneys Lane at the intersection with Taylor Run Parkway, and to perform stream restoration work in Taylor Run within the same vicinity.  This project provided for the realignment of a sanitary sewer to eliminate the existing siphon in the sewer system, replacement of damaged headwalls on existing culverts, and stream restoration work upstream and downstream of the culverts.    The construction was completed in December, 2014.

Backlick Run North Bank Erosion Repairs Project 

The City of Alexandria employed the services of Avon Construction Company for the construction of riprap slope protection along the north banks of Backlick Run immediately east of the concrete channel section of the run. Riprap is rock or other material used to armor shorelines, streambeds, pilings and other shoreline structures against scour, water or ice erosion.  The purpose of the project was to prevent further erosion of the north bank.  

During Tropical Storm Lee, which occurred from September 5 through September 9, 2011, the City experienced severe flooding in the Backlick Run Watershed that included Backlick Run. The severe flooding caused the riprap earthen embankment to be washed away.   The north bank's channel geometry has now been restored to original conditions.

King and West Diversion 

This project replaced the existing combined sewer overflow (CSO) diversion structure with a new CSO diversion structure, manhole and connecting sewer and appurtenances. This structure is accessible to City personnel and enables maintenance and observation with greater efficiency and safety than the previous structure. The project required the installation of an underground concrete structure to replace the diversion chamber. Safe access for observation of the condition and maintenance of the CSO is a primary part of the purpose of the project. The improvement to the CSO structure is a requirement of the City's combined sewer system VPDES permit issued by the Virginia Department of Environmental Quality.
