Public Invited to Comment on Multnomah County Stormwater Management

Multnomah County invites the public to review and comment on its annual report regarding its stormwater management plan.

New management practices

The county has stormwater management responsibility on county-owned roadways in the cities of Fairview, Troutdale, and Wood Village, the county-owned Willamette River bridges, and urban pockets of unincorporated Multnomah County. The Stormwater Management Plan is designed to minimize the impact from roadways, development, and county operations on water quality. The plan consists of seven categories of best management practices that provide a comprehensive approach to reduce stormwater pollution. These include activities such as catch basin cleaning, street sweeping, public education, land use permitting, and capital improvements. 

The report

The annual report is a requirement of the county’s National Pollutant Discharge and Elimination System Municipal Separate Storm Sewer (NPDES MS4) Phase I permit. The county solicits public comment and review of the stormwater management activities completed in the past year before the report is submitted to the Oregon Department of Environmental Quality.

The draft 2021 annual report is available online at https://multco.us/water-quality-program. It summarizes activities for the permit year ending June 30, 2021.

Written public comments on the plan can be submitted by October 26 at 5 p.m. to the Water Quality Program at water.quality@multco.us or 1620 SE 190th Avenue, Portland, Oregon 97233.
