Narrow Gauge Creekshed Study
Project overview
For several years, City staff have responded to inquiries regarding stormwater concerns in the Green Road/Narrow Gauge Way Nature Area. Specifically, the privately-owned detention basin in The Forest development receives runoff from the upstream area, including sediment from erosion in the entire upstream drainage area and runoff from the immediate neighborhood. The detention pond is working as it was designed in 1989, but requires maintenance and sediment removal. However, there are concerns regarding stormwater management and sediment erosion from the streambanks of Millers Creek, upstream of Green Road.
City staff has worked to complete a Drainage Study and Analysis of the entire upstream creekshed area to identify opportunities to minimize erosion and sedimentation along the entire Millers Creek channel. This project includes field assessment, hydraulic and hydrologic modeling, streambank assessment, and recommendations to address concerns that can be included in the City's Capital Improvement Plan (CIP) for future construction.
Project limits
Engagement
The city held three virtual sessions to share the study's drainage analysis and recommendations.
Cost and funding sources
This Drainage Study will cost an estimated $75,000 to be paid from the Stormwater Fund.
