City Program


Currently, the city has a guidance manual for city staff, property owners, developers, and neighbors to use to learn about the overall program and how to implement it. The guidance manual is one component of the Tualatin Basin program.

Removal of Barriers 

City staff, as part of the Tualatin Basin Steering Committee (TBSC), reviewed the Comprehensive Plan, the Development Code, the Engineering Design Manual and Standard Drawings, and the City Code to determine where barriers to use of the different habitat friendly development practices (HFDPs) existed. The result is the city’s Gap Analysis, which helped staff start the process of modifying the documents in order to remove, where possible, existing barriers. 


The city will work to provide multiple educational opportunities to people who are interested in HFDPs and best management practices (BMPs). Initially, staff throughout the city will receive informational packets and will participate in tours to locations in the metropolitan area that have BMP techniques implemented in the site design. Further outreach materials will need to be created and distributed to citizens, property owners, developers, and industry professionals. The guidance manual should be a good educational base. 

Encouraging Habitat Friendly Practices 

Finding ways to encourage use of HFDPs is also an important element of the program. Changes to the Comprehensive Plan include direction for implementation of HFDPs and educational opportunities, as well as adoption of the Comprehensive Plan Volume III Habitat Benefit Area Map

The Habitat Benefit Area Map depicts areas that were determined to have a habitat benefit through Metro’s inventory process. A proposed new section of the Development Code is specifically created to allow options that provide for flexibility in site design when proposed in conjunction with preservation of Habitat Benefit Areas (HBAs) and/or use of Best Management Practices (BMPs). The Engineering Design Manual and Standard Drawings may also receive a new section that is specific to BMP designs; yet, many options will continue to require separate approval of a modification by the city engineer to vary from the standards. City Code changes generally provide clarification for use of BMPs; however, proposed reductions to SDC fees associated with reductions to Effective Impervious Area (EIA) are also proposed. 

Adoption of a guidance manual is proposed as part of the city’s program. The guidance manual will bring all elements of HFDPs and use of BMPs together in one document so that citizens, property owners, developers and industry professionals will have a better understanding of how separate practices work together. The guidance manual may either be the product of the city, alone, or may be the product of the Tualatin Basin Partners for Natural Places as a base line for all jurisdictions in the basin.
