Here is some helpful information:
What is a green street facility?
- A green street facility is a small rain garden that collects stormwater runoff from streets.
- Green street facilities keep stormwater out of the sewer system and local streams.
- Green street facilities are important parts of the city’s green infrastructure and help protect and improve the efficiency of the city’s grey, or pipe, infrastructure.
- Green street facilities help prevent sewer back-ups in basements and combined sewer overflows (CSOs) to the Willamette River.
- Green street facilities increase urban green space, improve air quality, replenish groundwater, and reduce air temperature.
How does the city choose facility locations?
- To effectively manage stormwater, green street facilities must be located where they will benefit the sewer system. They are typically located close to storm drains.
- Green street width, length and depth are determined through research and modeling conducted by city staff.
- Other factors considered are the width of planting strips, the age and size of existing street trees, and parking impacts.
Do green street facilities reduce on-street parking?
- Green street facilities built within the right-of-way, or planting strip, do not remove on-street parking.
- Green street facilities that are curb extensions do remove parking spaces because they protrude into the street. A curb extension can remove two to three parking spaces, depending on its length.
- The city works with adjacent property owners to limit impacts while ensuring that green street facilities effectively manage stormwater.
- Because green street facilities are not as wide as cars, curb extensions give traffic more room to pass than parked cars do. A curb extension’s low-growing vegetation also improves visibility for drivers and pedestrians.
Green street care and maintenance
- The city is responsible for maintaining green street facilities. City staff generally conducts seasonal maintenance up to four times a year. The city also welcomes volunteer Green Street Steward partnerships.
- Maintenance staff leave door hangers for green street neighbors with a description of the work performed and contact information.
- Maintenance includes removing sediment, leaves or trash that can impede water flow and affect green street performance.
- Green street facilities should never be used to dispose of trash or animal waste. The city welcomes help from green street neighbors in keeping these materials out of green streets.
