It’s a change that likely won’t go noticed by many Alexandrians, but the city is making an adjustment to its manholes that could have an impact on flooding during storms.
According to Flood Action Alexandria — an ongoing newsletter highlighting flooding issues and mitigation measures in Alexandria — the City of Alexandria is working on finding a contractor to install 870 stainless steel manhole inserts around the city.
The National Weather Service has issued an areal flood warning for Alexandria.
“Avoid small streams and do not drive through water on roadways,” a release from the city said.
The City of Alexandria has launched a new interactive map that lets locals keep track of flood mitigation projects around town.
The interactive map shows all 35 ongoing projects around town, as well as two recently completed ones and seven future projects.
The National Weather Service has issued an Areal Flood Watch for Alexandria with rain expected this afternoon and most of this weekend.
While it’s clear skies this morning, the forecast for rain comes after heavy rainfall last night.
Some of the city’s biggest flood mitigation projects have been making progress in recent months.
In the same Flood Action Alexandria newsletter that highlighted some record-breaking rainfall in July, the city said two of the top-ranking, large capacity flood mitigation projects have “reached notable milestones.”
A storm that postponed the city’s birthday celebrations last month set a rainfall record in Alexandria according to a floodwater mitigation newsletter prepared by the city.
The Flood Action Alexandria newsletter, prepared by Flood Action Alexandria communications specialist Amanda Dolasinski, noted that a storm on July 9 set the record for rainfall recorded before 7 a.m. The newsletter said the city saw nearly 4 inches of rainfall in the northeast section of Alexandria and pushed Four Mile Run to to the 10-foot stage at Shirlington Road Bridge.
Alexandria and areas nearby are under a Severe Thunderstorm Watch this evening and a Flood Watch.
The National Weather Service issued a Flood Watch earlier today (Monday), cautioning flooding may occur this evening and a Severe Thunderstorm Watch is in effect until 10 p.m.
Alexandria leaders will be on-hand on Thursday, July 14, for the unveiling and dedication of AlexRenew’s RiverRenew Tunnel Project.
The $454.4 million project will replace Old Town’s 19th century combined sewer system with a tunnel system, sewer infrastructure and improvements to AlexRenew’s wastewater treatment plant — all to prevent 130 million gallons of combined sewage from flowing from four outfalls into the Potomac River every year.
The City of Alexandria has a handful of irons in the fire when it comes to stormwater management, but one new approach is one of the oldest tactics: storing runoff in rain barrels.
The city announced yesterday that it’s planning to offer a limited supply of free rain barrels, with more available via raffle at the city libraries.
A severe thunderstorm warning has been issued for Alexandria and the city is starting to see heavy rainfall.
The city is also under an areal flood watch.
Alexandria and Arlington will start clearing debris and dredging Four Mile Run in September, and the project will close sections of the park from the public for four to six months.
The City and County maintain a shared flood-control channel in the lower portion of the nine-mile-long stream, and have partnered to dredge Four Mile Run since 1974.
