City Council approved funding in the 2015-2017 biennial budget for this South Awbrey Butte Drainage Study capital improvement project. The associated project area included the southern hillside of Awbrey Butte as it directs drainage flows to the Newport Avenue Storm Sewer and all surrounding areas which drain towards Newport Avenue.

The Newport Avenue storm drain begins at the intersection of College Way and Newport Avenue, extending east to the outfall at the Deschutes River.

The selected consultant completed a drainage system analysis to identify drainage problem areas within the catchment area and along the Newport Avenue Storm Sewer. The drainage system analysis included areas which lack or have inadequate drainage facilities to manage a 25-year design storm event, unsafe passage of the 100-year design storm event, and areas of excessive concentrations of debris and other pollutants. The engineering consultant provided preliminary design solutions which meet applicable regulatory requirements. Preliminary design solutions were provided to solicit feedback from internal and external stakeholders.

The final deliverable was submitted in the form of a drainage report and will be a comprehensive report describing the project area, process, and final deliverables.


The project objective is to develop a prioritized stormwater project list which provides a systematic and cost-benefit balanced approach to improve deficient segments of the Newport Avenue Storm Sewer and upstream basin drainage problem areas.
