Clear Creek Federal Flood Risk Management Project

Aurora currently serves as the lead engineer to provide utility coordination and engineering efforts as well as support for construction phase services as part of the Owner Advisory Team. The Clear Creek Federal Flood Risk Management Project is a major partnership project between HCFCD and the US Army Corps of Engineers (USACE) to improve a significant portion of the Clear Creek watershed including three 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.

The flood risk management scope for the Clear Creek Federal Project includes conveyance improvements of 15.2 miles of Clear Creek channel from SH 288 to Dixie Farm Road, 2.4 miles of Turkey Creek channel from Dixie Farm Road to Clear Creek, 0.8 miles of Mud Gully and 2.1 miles of Mary’s Creek channel from Harkey Road to SH 35. The project also includes the improvement of up to 485 acre-ft of in-line detention as well as channel realignment, stream bank preservation, and sediment abatement features.

To support utility coordination and engineering efforts, Aurora is responsible for utility conflict identification and validation as determined from previous work by the USACE and HCFCD, other utility investigations, and coordination with utility facility owners. The scope includes evaluating alternatives to avoid or mitigate conflicts or plans for adjustment. Notable challenges include numerous utility relocations such as pipeline crossings, oil wells, public and private utilities, and 13 bridge structures. Close coordination with the project team and scheduling is one of the major critical path efforts to plan and execute utility adjustments and to achieve the intended project schedule.

The scope also includes Subsurface Utility Engineering (SUE) Quality Level field locating services such as QL-A test hole investigation and QL-B utility designation services. Project responsibility is to provide utility conflict verification including surveying and field reporting in assessing and supporting the utility conflict coordination and related relocation efforts.
