Fayetteville is making plans to address recurrent flooding in a neighborhood in the southeast part of the city.
The city council last week unanimously gave the go ahead to design a flooding mitigation plan for the Locks Creek area. It’s estimated to cost $8.8 million.
The project would improve drainage among roadways in the neighborhood, including the primary throughway, Locks Creek Road, which will also be elevated as part of the construction.
Byron Reeves, the city’s stormwater manager, said the purpose is to give access to emergency help to households in the event of a flood.
“When you get certain storm events, you can’t get in and out of the neighborhoods, no emergency access, people can’t get in and out to their homes,” he said.
This is the first phase, the only one approved last week. A second phase would call for a bridge on nearby State Road 53.
If that second phase is eventually approved, the entire construction, including phase 1, is estimated to cost $24.5 million.
Reeves said the primary purpose is to serve the 180 houses in the neighborhood that do not flood. The flooding among the homes along Bombay Drive and Turkey Run, however, would continue.
At last week’s council meeting, Mayor Mitch Colvin said the plan is a partial fix.
“You still have Bombay Drive, which is one of the most impacted ones,” he said. “Those are the folks that come in year after year — after the two hurricanes — about flooding.”
To address the flooding of the homes, Reeves said, little can be done in terms of new construction.
“We can’t fix everything out there, however, we can do some things out there to improve the infrastructure for some in the neighborhood,” he said.
Another option presented to the council was to pay fair market value for the homes that flood and turn them into levees to prevent further flooding in the area.
However, this buyout though cannot be funded federally as the Federal Emergency Management Agency does not consider the area a floodplain, a requirement for FEMA’s hazard mitigation assistance program.
The current flood designation only extends within the immediate area of the Cape Fear River, miles west of the homes.
If the houses were in a FEMA floodplain, a buyout could be issued in which the federal agency would pay for 75% of the costs. The rest would be paid by either state or local funds, if the homeowner agreed.
Since FEMA funds aren’t on the table, however, the council last week was presented a second option, which includes all the roadway mitigation efforts from the first, where the city would front all the costs of property acquisition. It costs much more, $45 million in total.
If they wanted to consider that plan in the future, the council was encouraged to search for grant funding as the stormwater budget wouldn’t cover such a price.
‘Water always wins’
Even if the city obtained enough funding for the $45 million option, it wouldn’t stop all the flooding in the area.
The levees wouldn’t completely stop waters reaching north of the neighborhood around L.A. Dunham Drive.
“It’s very challenging to mitigate all the flooding out there,” he said. “You’re putting a lot of money in. It’s not solving the problem. You’re mitigating it, but you’re not completely mitigating it.”
Matthew in 2016 and Florence in 2018 were historic hurricanes for Fayetteville. They resulted in two floods that are typically only seen once in a 500 year span, according to research from the U.S. Geological Survey.
The study presented to the council last week for the Locks Creek watershed only accounted for 25-year flood events.
If another hurricane of the same magnitude hit the area, it would likely surpass these expensive mitigation measures, Reeves said.
“There’s some storm events that you just can’t design your way out of,” he said.
Mayor Pro Tem Kathy Jensen, at last week’s meeting, said further discussion is needed before the council considers paying $45 million to address only a 25-year flood.
“Water always wins,” she said. “It always winds up taking.”
