Dardenne Prairie recently examined a project that would install a new one-way, low-flow spillway pipe at the 15-acre lake at the Dardenne Greenway in BaratHaven Park. It also would install a trailside concrete swale to direct stormwater from the Henning Road bridge to two existing plastic cross-trail culverts, both of which will be extended to Dardenne Creek.
Currently at Dardenne Creek, the spillway allows creek water to flow into the lake when water rises, also carrying silt and making the lake shallower. Additionally, it allows water and mud to flow onto the lakeside walking and biking trail. The new one-way spillway would prevent that from happening.
During heavy rain, stormwater from the Henning Road bridge drains currently flows directly down to Dardenne Creek and both of its banks and onto the park walking and biking trail near the bridge underpass. The new concrete swale also would prevent that from happening.
City staff solicited sealed bids and received three, which were made public on Sept. 25. The low bid was from Two Alpha Contracting, LLC, for $81,024.
The ordinance [Bill #19-36] requested the authorization of the mayor to negotiate and execute a contract with Two Alpha Contracting for the project.
At its Oct. 2 meeting, the Board of Aldermen voted 6 to 0 to pass the bill.
