North Ridgeville proposes two projects to ease flooding

NORTH RIDGEVILLE — Two pending sewer projects are designed to reduce the devastating impact of future flooding.

One improvement is a nearly $500,000 sewer line change that should boost the speed with which sewage and water enters the city’s French Creek Wastewater Plant.

The other is an alteration in a weir, or low concrete, that regulates the flow of stormwater held behind a dam.

The planned changes ideally will lower stormwater by up to six inches for residents of the Gina-Pitts-Gail Drive area, which has sustained some of the worst flood damage in the city over the past 20-plus years.

Both projects are to be done this year, said Mayor David Gillock.

The smaller project calls for an $18,300 modification of an opening at the top of a 60-foot-wide concrete dam that runs parallel to Root Road north of the Ohio Turnpike.

The dam, which is 12 to 13 feet tall, was built in 1998, and retains stormwater before releasing it into a detention basin off West Point Drive, which runs parallel to Bainbridge Road. The detention basin releases stormwater into a nearby ditch that carries it north out of the city, said Assistant City Engineer Cathy Becker.

The change in the dam was recommended by an engineering study and would dovetail with recent work to dig the detention basin substantially deeper to hold more stormwater, Gillock said.

Plans call for a small opening at the top of the weir to be altered to retain more water behind the dam.

City officials are checking calculations to determine whether putting more water behind the dam can be achieved without putting too much pressure on the dam, Becker said. If the dam was to shift or begin to give way due to extreme pressure, it could lead to serious flooding upstream, or south of the dam.

If needed, the area of the dam around the altered opening could be reinforced with steel to prevent it from possible collapse, Becker said.

Stormwater is generally held for up to 12 hours behind such dams before being released into drainage ditches, she said.

“If water comes across (residential) yards in a big storm, and you have two inches in front of your door, lowering that by six inches should prevent flooding,” Gillock said. “We’re not saying this is a cure-all, but it will certainly help.”

The French Creek Wastewater Treatment Plant project is a $470,000 enlargement of sanitary sewer lines at the entrance to the plant on North Abbe Road.

Plans call for the removal of a 90-degree, T-shaped sewer line connection that links south and northbound lines into a single pipe that moves into the plant.

The T-shaped line would be replaced by 42-inch pipe containing two 45-degree bends to move water and sewage more quickly into the plant through a much bigger 60-inch line, Gillock said.

Over time, the T-shaped connection has deteriorated, Gillock said.

    I am strongly opposed to any attempt to retain more water in
    the West Point weir. Possible collapse, checking calculations all are speculation.
    Water runs north, if you stem the flow at West point it will just flood further south on WestPoint, Blanchard, Chennault, Timothy, Denny, Grant, perhaps Bainbridge.

    I’m not unsympathetic to the Gina drive problem, but most of
    these houses around West point are ranches, a flood will cause the loss of everything and as we all know there is no insurance for non flood plain areas.

    Again I am sympathetic to areas flooded, however people here
    bought homes with no basements and understanding there was no flooding. Gina drive area has been flooding for decades.

    This just sound s like its moving the problem and should the city create the conditions that cause flooding what recourse will homeowners have.

      33% of all flood damage insurance claims come from property outside of
      the 100-year flood plain. Floodsmart.gov is a start and if you find the
      coverage to be too low, additional specialized policies and/or homeowner riders can be purchased.

      It is up to each property owner to do the cost-risk-benefit analysis but to say the products are not available is simply untrue.

      • Dan F

        Your right, I should have said affordability instead of unavailability. I guess the point is why do I have to insure for something not from acts of god but by actions that the city is taking. Seems that I should not have to bear the financial burden.

    • Kevin Jenkins

      Screw you Dan. We do not care what you are opposed to. I hope your house floods, because you are not sympathetic at all.

        Nice post… real poetic

  • Fred Garvin

    N.R. has been duped by the developers. With the expression on the mayors face during council meetings, it is clear to me he does not care anymore and needs to be voted out in the next election.

  • Fred Garvin

    The city needs to find out why the sanitaries are backing up. Storm water is not supposed to have an effect on the sanitaries. Illegal connections are to blame.

  • Sis Delish

    Build a reservoir, bottle the water, and sell it world-wide under some fancy name like “Ranger Danger”, or “Whet yer whistle, with Corn Festival fissile”.

  • Fred Garvin

    N.R. needs term limits so these career politicians can be booted out and get some new ideas in city hall. The mayor does little and seems to be bored listening to the people who have to put up with this constant flooding. They need more than the periodic ditch cleaning and the nonsense of getting 6 inches of rain in one hour. Sounds like excuses.

  • Nita Morrison

    How about this: reline or repair the outdated, inadequate sewer lines so storm water does not infiltrate sanitary sewers? Seems like City government is pussyfooting around that solution.
