Maintaining and improving the City’s 213 miles of storm pipeline, 5294 catch basins and 3042 maintenance access holes are major functions of the Subsurface Drainage subprogram. Maintenance activities include catch basin and pipeline cleaning, root sawing and repairing maintenance access holes and pipes. This program also provides information on design, inspection and construction of new storm drains for capital improvement projects, planning, and mapping.
The goal of Subsurface Drainage is:
- to efficiently and effectively maintain the subsurface storm water drainage system,
- to maximize the system capacity
- to minimize the occurrence and extent of localized flooding
- to improve the quality of urban storm water runoff discharged to rivers.
The City works with a variety of volunteer groups on the Storm water Drainage Awareness Program (Fish Stenciling).
Volunteers stencil warnings “No Dumping – Drains to Streams” at catch basins around the City to help educate the public. The City of Springfield took the lead in finding a solution to a problem that faced all municipalities regarding the disposition of vactor waste material removed from the subsurface drainage system. In a combined effort of the City of Springfield, City of Eugene and Lane County, a storm water waste facility was built. Each agency disposes of their catch basin debris at this facility until well-drained. The dried material is then hauled off to the county landfill.
