Overview and History

In December of 2017, a tree fell into the drainage channel immediately upstream of the City’s M-1 Dam. This dam was constructed in 1987 (prior to the City’s incorporation) to provide inline stormwater detention within the Boeing Creek basin. In-channel flows diverted by the tree caused substantial erosion damage to the maintenance access road adjacent to the channel. The access road is used primarily for general maintenance of the dam, including access for larger equipment to clean the sediment trap.

The City’s Surface Water Utility engaged an on-call consultant to study and prepare a preliminary design recommendation for the repair of the access road. During review of the repair process, it was determined that a broader analysis of the channel and side slope configuration was advisable in order to identify proactive mitigation strategies for potential future problems. 

This project will evaluate and progress the project design to final and construction for these improvements.
