To: Chair Thiesse and Planning Commission Members Dustin Rief, City Administrator From: Melanie Curtis, Planner mcc Date: 17 September 2018 Subject: #LA18-000057, Text Amendment: Accessory Building & Structure Setbacks Memo #4 - Public Hearing - Continued Application Summary: The draft ordinance would re -organize the regulations, and clarify the setbacks for accessory buildings and structures throughout the City. Staff Recommendation: Planning Commission should continue the public hearing opened in June and discuss the proposed format and amendments. Staff will prepare an ordinance for future consideration, based on input received. Background/Update This is a continuation of the discussion beginning in June, regarding proposed changes for Accessory Building and Structure setbacks. The changes discussed thus far have been regarding the overall organization of the regulations in the Code, and whether or not adjustments to the existing setbacks are needed. For the August meeting, Staff prepared a summary of the existing regulations in a newly organized table format, as well as a table showing proposed changes to the setbacks for the R - 1A, R1 -B, LR -1A, & LR -1B districts. The proposed changes to the setbacks shown reflected the feedback from the previous discussions with the Planning Commission. Staff took the feedback given at the August meeting and continued to develop the remainder of the residential tables continuing the same agreed-upon philosophy. The RS District (i.e. Big Island and Deering Island) has some additional complications and staff is seeking guidance on how to proceed regarding accessory building/structure setbacks in that district. For clarification: AS = Accessory Structure, anything which is built, constructed, erected, etc... AB = Accessory Building (a structure with a roof) less than 1000 square feet OAB = Oversized Accessory Building a structure with a roof exceeding 1000 square feet Planning Commission should review the additional tables and the setbacks contemplated within; some are new and some are a clarification on the existing. Additionally staff asks that the Planning Commission provide direction on the following questions/topics: RS Seasonal Recreational District - Big Island/Deering Island. The current minimum side yard setbacks for all structures and buildings are based on the width of the property. For example: Lots 200 feet or more in width have a minimum side setback requirement of 50 feet. Lots greater than 100 and less than 200 feet in width have a minimum side setback requirement of 30 feet. And lots less than 100 feet in width have a minimum 10 foot side setback. This can also be accomplished similarly to our recent setback flexibility for lots with nonconforming widths where we permit the side setback to be 10% of the lot width but not less than an appropriate minimum (10 or 7.5 feet, etc.).
