To protect natural resources and conserve scenic and historic areas and open spaces. Local governments shall adopt programs that will protect natural resources ... for present and future generations. These resources promote a healthy environment and natural landscape that contribute to Oregon's livability.
The Goal 5 rules require the County to inventory certain natural resources, assess their quality, determine levels of protection and adopt policies/rules based on the desired level of protection.
The County’s Goal 5 program was completed in the early 1980s. The inventory process included identification and mapping of 2,400 acres of fish and wildlife habitat. Natural resource policies and standards were developed and implemented through Comprehensive Plan elements, and the program was approved by the state.
The Community Development Code (CDC) addresses two primary types of SNRs:
If a development “seriously interferes” with wildlife habitat and water-related habitat areas, the developer must reduce the impact and/or offset the loss of habitat values from development (mitigate).
In 2005,Washington County collaborated with cities, Clean Water Services and Metro to approve the Tualatin Basin Program, a regional fish and wildlife protection plan for determining consistency with Goal 5. The program limits development in valuable riparian corridor/habitat areas and encourages habitat protection with habitat-friendly designs and incentives for developers. Some changes to the County's regulations were part of this process.
