Rain Garden Resources
Typically, a rain garden is a small- to medium-sized garden planted in a shallow depression, and often includes native plants. The specialized plants and soil slow runoff during heavy rains and provide natural filtration for several common pollutants. Rain gardens can also be designed to provide habitat for birds, butterflies and beneficial insects.
The City of Eugene installs rain gardens to treat stormwater in public areas, and requires new developments to incorporate them to handle water from downspouts, streets, roofs and other impervious surfaces. They are considered a best practice by the Environmental Protection Agency, so support water quality policies that are reported as part of our NPDES permitting.

Eugene’s municipal stormwater system, comprised of catch basins, pipes, ditches and waterways, conveys runoff from properties within the City and drains directly into the Willamette River and other local waterways such as Amazon Creek. A Federal discharge permit requires the City to implement a comprehensive stormwater management program that establishes controls on stormwater runoff from developing areas to protect local water quality.
The Stormwater Management Manual (SMM) outlines specific requirements that Public Works engineers, developers and designers must follow in constructing stormwater facilities. This includes sections for several types of rain garden facility designs, operations and maintenance.
