Glenrose Watershed

The Glenrose Watershed encompasses the southeast corner of the City of Spokane and the unincorporated area that wraps around that portion of the City. Many residents contend with flooded basements, crawl spaces and intersections, soggy lawns and muddy debris in garages, driveways and yards. Landowners developing their properties have become aware of the difficulty of finding safe places to dispose of the additional stormwater runoff created by new subdivisions and commercial buildings.

The County’s construction of a storm sewer in Glennaire Drive on Browne Mountain and the construction of a grass-lined channel to the north were two early projects of the regional stormwater system. The next project was constructed in 2008 and is called the Browne Mtn. Regional Stormwater Facility.  The site is located near 46th and Sumac and is on land where the City of Spokane once maintained sanitary sewage lagoons.  The land is now owned by Spokane County.  Design and construction of more facilities will occur in future years.

Public opinion and input regarding regional facility planning and design is highly valued.  Input is gathered through public meetings for all of these projects.  Notices/ads are placed in the Spokesman Review and property owners in the vicinity of proposed sites are notified by mail.  We also make every effort to keep our web information up to date by posting notices and progress reports so you may want to check back periodically to see if there is anything new going on.
