Title
AUTHORIZE THE MAYOR AND CITY MANAGER TO ENTER INTO A CONTRACT WITH COON CREEK WATERSHED DISTRICT IN THE NOT TO EXCEED AMOUNT OF $14,200 FOR LADDIE LAKE OUTLET AND FLOOD MITIGATION STUDY
Background
On September 28, 2017, the Engineering Department requested assistance from the Coon Creek Watershed District to conduct a flood mitigation study for the area that drains to Laddie Lake as well as alternative designs for the outlet control structure at Laddie Lake. Coon Creek Watershed District has provided a proposal to do the work in the not-to-exceed amount of $14,200.
The goals of the study will be to verify the location, depth, size and duration of flooding in the minor subwatershed draining to Laddie Lake; identify the pipe sizes and alternative practices needed to remedy the flooding situations; identify the preferred construction sequence for use in the City’s CIP and present five different design options to treat stormwater and alternative designs for the outlet control structure on Laddie Lake.
Recommendation
By motion, authorize the Mayor and City Manager to contract with Coon Creek Watershed District in the not-to-exceed amount of $14,200 for Laddie Lake Outlet and Flood Mitigation Study.
