Summary
A city with a population over 2,500 in its urban growth boundary (UGB) that adds more than 50 acres to its UGB submits the amendment to DLCD for review. Based on this review, the DLCD director decides whether the amendment complies with applicable laws and whether to approve the submittal. A UGB review includes analyses, findings, and conclusions regarding whether there is a need for an expansion, if so how much, and if so where the expansion should be located. Currently, such amendments often must be submitted as one package when all of the various components are complete and adopted by the city and county.
Senate Bill 418 (2017) created a new process by which local governments may submit these components to DLCD in sequential phases, and DLCD will review the component and make a decision on it prior to the completion of the final UGB amendment. The legislation created the new process, but details of how it works will reside in administrative rules.
The Land Conservation and Development Commission 
adopted administrative rules to implement SB 418 at its January 2019 meeting. The DLCD report to LCDC explains the amendments.
