The Clear Creek Federal Flood Risk Management Project is a major partnership project between HCFCD and US Army Corps of Engineers (USACE) to improve a significant portion of the Clear Creek watershed including three of its tributaries for flood damage reduction. The purpose of the Owner Advisor Team is to assist HCFCD in planning, scoping, contract and procurement support, engineering and construction phase support, programming, and implementing a Design-Build project delivery.
