Surface Drainage

The Surface Drainage program strives to balance flows of stormwater with improving the cleanliness of the stormwater runoff discharged to the McKenzie and Willamette rivers. The surface drainage system includes cross country canals, roadside ditches, culverts, bridges, ponds, swales, wetlands and the Springfield Mill Race. The surface drainage system comprises the visible components of the City's stormwater system. The underground components; pipes, catch basins and water quality manholes are part of the Subsurface Drainage program. 

In 1996 Springfield began requiring subdivisions to build water quality facilities to clean stormwater before it enters the stormwater system. Developers built ponds and swales, and restored wetlands to filter stormwater. These facilities are now prevalent in most subdivisions. The Surface Drainage program works with the Environmental Services Division to ensure these facilities effectively clean stormwater

The Operations Division makes sure the facilities do not flood and operate properly.  These facilities are often plugged by illegal dumping of debris and yard clippings (Springfield Municipal Code 4.372 Illicit Discharge).


The activities to maintain surface drainage systems include excavating sediment build up, removing litter and debris, controlling invasive plants and weeds, trimming trees and shrubs, mowing, bridge inspection and repairs, and cleaning culverts.

The Springfield Mill Race is a unique waterway that provides water for industrial users, and irrigation and stormwater conveyance. It was hand dug in 1852 by Elias Briggs, and in 1985 Georgia Pacific donated the Mill Race to Springfield.  In 2009 the Army Corps of Engineers began an enhancement project creating a stable inlet at Clearwater Park, which included removal of the Mill Dam, riparian restoration, and creation of wetland and backwater sloughs in the former Mill Pond area.

Maintaining and improving the City's 206 miles of storm pipeline, 6,520 catch basins and 3,042 manholes are major functions of the Subsurface Drainage subprogram. Maintenance activities include catch basin and pipeline cleaning, root sawing and repairing manholes 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 stormwater drainage system,

  • to maximize the system capacity

  • to minimize the occurrence and extent of localized flooding

  • to improve the quality of urban stormwater runoff discharged to rivers.

Drain to river

The City of Springfield took the lead in finding a solution to a problem that faced all municipalities regarding the deposition 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 stormwater 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.
