The first repair phase will cost about $220,000, said Kathy Bartlett, service director for Riverside, something the city has the ability to pay for. But in a feasibility study from last year, estimates of the wall replacement ranged from between $7 million to $8 million and up to $15 million.
The city plans to have a project in place to replace the current road and wall by 2025 or earlier. The city can’t move forward on the project until they have funding in place, she said, but the city plans to work with an outside group, the Montgomery County Transpiration Improvement District, which would help the city figure out what funds and grants they may be eligible for.
“They’re instrumental in trying to secure funding for projects like this, because it’s really more than the city can handle by itself,” Bartlett said.
City council will vote on Thursday on whether to start a contract with the Montgomery County TID.
Bartlett said the need to replace the wall and the road is high at this point.
The curvature of the road is no longer up to standards, she said. There have also been multiple car accidents where people crash into the wall. More than 20,000 vehicles a day travel on the roadway.
Before the wall was first built, there were several head-on collisions, including at least one death.
Now, the wall is about 50 years old and concrete only lasts for about 50 years, Bartlett said.
Bartlett said two sections of the wall also bowed out during the heat of the summer and they are no longer stable. During an inspection over the summer, the city discovered there were ants in the wall.
Sara Lommatzsch, deputy mayor, said during a city council work session Thursday the city needs to fix the wall because it’s a liability.
“I think the liability of not fixing the wall is what we have to put front and center,” she said.
The city plans to replace the current roadway and wall with a redesigned road with grass in the middle. There will also be curbs and gutters along the side of the road, which would make the road feel narrower.
Making the road feel narrower so people are forced to go slower could help with the accident problem, Bartlett said. The current speed limit on that road is 45 mph. The city has also suggested dropping the speed limit on the road to 35 mph.
Bartlett said beginning next year, the worst parts of the wall should be fixed.
“The first phase of repairs should take care of the worst sections in that inspection which took place this summer,” Bartlett said.
