Alexandria’s worked on some high-tech flood mitigation projects, but sometimes the old ways are best.
The city is starting work this month on a project to replace a concrete retaining wall in Rosemont with a reinforced vegetated wall, a replacement that should not only benefit the local ecosystem, but help protect a nearby sewer line.
“Construction is expected to begin this month on a project to replace a retaining wall along Timber Branch near Oakland Terrace,” the city’s flood project newsletter said.
The project is scheduled for completion later this year.
According to the newsletter:
The contractor will be replacing more than 200 feet of an existing concrete retaining wall with a reinforced vegetated wall.
The $300,000 project will help protect the nearby sewer line, as well as stabilize the stream bank to reduce the chance of further erosion and mitigate flooding in the neighborhoods near Oakland Terrace.
The project is budgeted for $2.5 million.
