The NROD regulates water quality and ensures habitat protection through the enforcement of permanent vegetated corridors between sensitive resources and developed areas. The NROD map and code are in compliance with Titles 3 and 13 of the regional Metro Urban Growth Functional Management Plan.

Also, the NROD helps to implement the Oregon City Comprehensive Plan Natural Resource Goals and Policies, as well as promoting federal Clean Water Act requirements for shading of streams and reduction of water temperatures. The NROD is intended to resolve conflicts between development and conservation of habitat, stream corridors, wetlands, and floodplains identified on the City's adopted maps.
