Public Involvement: The goal of the communication program is to create an open and transparent process that provides the opportunity for interested members of the public and internal staff to participate in the development of codes and supporting materials so they understand and feel ownership of these changes at the end of the process.

Why Now?
The timing of this project is driven primarily by the City's NPDES-MS4 Permit, a requirement of the Clean Water Act. Municipalities operating stormwater systems are required to obtain a NPDES-MS4 permit to discharge into waters of the State (like Oswego Lake or the Willamette River). Lake Oswego is included under an MS4 permit issued to a group of Clackamas County jurisdictions. The permit is due to be reissued in the Fall of 2011, and then the City must respond with updated codes and policies to meet the new requirements. Here are the reasons for pursuing this project now:

  1. New permits require Lake Oswego to change some of the ways it addresses stormwater in the City
  2. This project also addresses several City Council goals.
  3. It addresses the Community Vision outlined in the City's Comprehensive Review process - to be "Good Stewards of our environment" - When asked what aspects of Lake Oswego's natural environment they believe will be of most value to them and future generations in 25 years, most respondents said healthy watersheds (Source: This effort is one very tangible way for the City to work toward achieving that goal.
  4. The public needs and deserves an easier and more cohesive process - stormwater requirements are not organized in one place, they can be hard to understand and difficult to implement.
  5. Changes can make our stormwater treatment facilities more effective, attractive, and better at protecting Oswego Lake, Willamette River, Tualatin River and Tryon Creek and our other water resources in the community.
  6. The regulatory agencies and Lake Oswego City Council have supported a shift to low impact development.
