EVEN MORE DETAIL
Jeffersonville’s Drainage Board issued a request for proposals to conduct an even more detailed flood mapping study.
The project was one of 11 projects planned to begin this year from the recently approved stormwater masterplan. The scope of the project consists of a flood depth mapping study for the tributary at Woodland Court to Lancassange Creek and updating a stream hydraulic study for the same tributary.
“We know there’s flooding through here, we want to know how bad it is,” Crouch said.
The city is looking for answers on whether or not floodproofing a home’s doors and windows will be enough to mitigate the flooding problems for the residents in the area or if the home would be submerged under water if a flood were to occur. The later scenario may force the city to enter into some voluntary buyouts of the affected properties.
The request for proposal would require on-site surveying and mapping of the area’s terrain.
“This is going to be much more detailed than what we gave FEMA,” Crouch said.
The proposals are due to be turned into the city by 3:30 p.m. Tuesday, July 30.
