Stormwater Master Plan

In June of 2003, the City of Milwaukie initiated a project to develop a stormwater plan to replace the previous master plan developed in 1997.

The previous plan covered only the portion of the City draining into Kellogg Creek and it was based on roughly estimated data regarding the existing stormwater system.

In addition the previous master plan did not address potential compliance issues associated with the Clean Water Act, the Safe Drinking Water Act (i.e, Underground Injection Control requirements for stormwater), and the Endangered Species Act.

Therefore, the objectives of this 2003 plan were as follows:

• Compile and evaluate physical data regarding the existing storm system.
• Develop a City-wide plan that enables the City to meet its flood protection needs.
• Address stormwater quality and hence support compliance with associated regulatory requirements associated with both surface and subsurface discharges of stormwater runoff.
• Evaluate the existence of barriers to fish passage and the potential for removal of those barriers to address Endangered Species Act issues for threatened and endangered anadromous salmonids.
