On Thursday, September 10, flooding was reported all through town within the newest of a string of summer season climate occasions which have shut down swaths of roadways, flooded alleyways and houses. The town despatched out an advisory warning residents of “indoor sewer backups, impassable roads, energy outages, and different flood-related points.”

Mayor Justin Wilson stated that town is planning infrastructure enchancment tasks in its 10-year Capital Enchancment Program.
“In the present day, Alexandria spends a big amount of cash on infrastructure designed to handle water,” Wilson wrote in his month-to-month publication. “In April, the Metropolis Council permitted a $2.1 billion, ten-year Capital Enchancment Program. Of that, over $150 million is to handle stormwater and sanitary sewer infrastructure. Alexandria Renew Enterprises, the Metropolis’s sewer authority, plans one other $593 million of capital investments over the subsequent decade, primarily the RiverRenew venture to remediate the Mixed Sewer (sanitary and stormwater) system that serves Previous City.”
The town can presently deal with a 10-year storm, however the July 8, 2019, and the July 23, 2020, storms have been “extra intense than this design commonplace, with the July 23 occasion about 30 occasions extra intense,” in keeping with town. “Out of the 83 ‘drawback areas’ within the Metropolis’s eight watersheds, the highest two watersheds have been Hooff’s Run and 4 Mile Run, with 23 ‘drawback areas’ every. Extra detailed planning and evaluation will happen to evaluate the general implementation feasibility (together with building) previous to full design of those large-scale capital tasks.”
The mayor’s full message is beneath.
In 2011, the Metropolis’s flood zone maps have been final up to date, increasing the flood zones in Previous City, Rosemont and Arlandria. The enlargement of those zones prolonged the variety of property homeowners required to buy insurance policies from the Federal Emergency Administration Administration’s (FEMA) Nationwide Flood Insurance coverage Program (NFIP) as a situation of their mortgage.Each property proprietor is eligible to buy FEMA Flood Insurance coverage. Whereas it’s only required for these in higher-risk areas, given the unpredictability of flooding, the acquisition of flood insurance coverage is beneficial.Whereas flood insurance coverage insurance policies may also help stop monetary smash when property homeowners are confronted with extreme flood occasions, infrastructure (each “gray” and “inexperienced”) funding may mitigate the affect of extreme flooding occasions.
A climate-resilient Metropolis requires investments and probably new insurance policies to make sure that residents of our Metropolis don’t endure devastating injury with such frequency.
Collectively, practically $750 million is deliberate for water investments. This spending dwarfs deliberate investments in colleges, transportation and different main priorities.
The investments required in our Sanitary Sewer system are funded by upkeep charges paid by present clients (additionally on the Alexandria Renew Enterprises payments) and by connection charges paid by builders.
The payment applies to all property homeowners (no matter their taxable standing). For industrial properties, it’s assessed primarily based on the impervious surfaces on the property. For residential properties, there are 4 tiers (residence, townhome, small single-family residence and huge single-family residence). There’s a credit score system in place to encourage actions that help the Metropolis’s storm sewers. Basically the payment is structured to be a consumer payment for the Metropolis’s stormwater dealing with.
- $51 million for water high quality infrastructure initiatives required underneath our MS4 Allow
- $19.three million for stomwater capability enhancements
- $5 million for stream and channel upkeep
A number of the particular drawback areas that now have recognized stormwater tasks are:
- Carlisle Drive Alley
- Founders Park
- Key Drive (Unnamed Tributary channel wall)
- Lloyd’s Lane
- Loyola Road
- Oakland Terrace (Timber Department channel wall)
- Saylor Place
- W. Alexandria Alley
For Alexandria, a 10-year storm occasion constitutes one that can drop 2.28 inches of rain over a 60-minute interval or 4.81 inches over a 24-hour interval. This can be a capability that’s at, and in lots of circumstances above, that of neighboring jurisdictions.
Setting up the infrastructure that may assist a altering local weather will likely be a big endeavor for our group. It’s going to contain a big dedication of recent assets and presumably property impacts.
But it’s my perception that this work requires better urgency to guard the property homeowners impacted in our Metropolis.
