The 1981 legislature adopted laws that require cities and counties to review their comprehensive plan periodically, and make changes necessary to keep those plans up to date and consistent with the statewide planning goals. The state's Land Conservation and Development Commission (LCDC) coordinates such reviews with Oregon Administrative Rule 660, Division 19, "Periodic Review."

The regulations require each local government to adopt findings responding to four periodic review factors and to take necessary steps to maintain local Plan and Land-use Regulations in compliance with such factors. This draft review will provide the findings to the program's past comprehensive plan in order to satisfy the periodic review requirements.
