Milo Creek Flood Control Improvements

Kellogg and Wardner, Idaho

PROJECT OVERVIEW

Welch, Comer & Associates, Inc. provided engineering services, in association with TerraGraphics Environmental Engineering, Inc., for repairs to the Milo Creek conveyance system which allowed floods to damage the town of Kellogg, Idaho and threaten the town of Wardner, Idaho.  Immediately following the spring 1997 floods, Welch Comer began work to complete temporary emergency repairs to the creek's conveyance system, and then continued work into the year 2000 to complete a comprehensive storm system to prevent future flood damage to the communities.  Welch Comer completed preliminary engineering studies and provided design, bidding and construction phase services throughout the project’s three phases.

Phase 1 and 2 local storm water improvements consisted of approximately 20,000 feet of pipe to avoid conflicts with the dual 54" high-density polyethylene (HDPE) pipes.  Welch Comer's design utilized storm pipes ranging in size from 6-inches in diameter to 36-inches in diameter.  The storm water system handles runoff water, but also serves to collect water from the prevalent springs and reroutes storm flows that previously entered the abandoned Milo Creek Channel.  Completing design and construction of the new system to successfully mesh with the existing system required close communication with the local residents and governmental officials who were familiar with the existing system's characteristics.  The local storm sewer improvements were constructed in conjunction with the 54" HDPE storm water improvement project.
