SEPA DETERMINATION OF NON-SIGNIFICANCE (DNS), and NOTICE OF PUBLIC HEARING (NOH) RESIDENTIAL DENSITY BONUS, ZOA26-0005 and SEP26-0009 The City of Auburn is issuing a Determination of Non-Significance (DNS), and Notice of Public Hearing (NOH) for the following described project. The project application and listed studies may be reviewed by contacting the Department of Community Development at planning@ auburnwa.gov or by visiting www.auburnwa.gov/landuse. Proposal: The proposal is a non-project action to implement the amendments to the Revised Code of Washington (RCW) 35.21.990 for New housing in existing buildings—Prohibitions on local regulation. The code was previously implemented under ACC 18.02.067, Units allowed per lot, to allow for density bonuses of up to 50 percent within existing buildings located within commercial or mixed-use zones. The amendments within the RCW and proposed within the ACC will expand that allowance to all residential zones, specifically the RC, R-1, and R-2 Zones, and provide further clarification on when and where energy code updates are required during the proposed density bonus within existing buildings.
