Overview
Euclidean base zones with hybrid naming: R-1 uses lot-size-suffix variants (R-1-5, R-1-6, R-1-7500); R-M is density-based multifamily; commercial uses alphabetic-type naming (C-N, C-R, C-S, C-MU, D-MU); office splits into O-PA and O-C; industrial splits into I and I-L; plus Quasi-Public (QP), Business Research Park (BRP), Airport, Agricultural (A), and Open Space (OS). Chapter 17.32 (Special Provisions) governs mixed-use residential standards, trash storage, home occupations, mobile home parks, emergency shelters, B&B, wireless facilities, and micro-brewery standards. Chapter 17.30 carries the development standards tables (not retrieved live due to amlegal 403). ADU Ordinance (2025-01-21) and Single-Family Objective Design Standards (2025-05-05) are recent amendments. Downtown Retail Design District and Historic Preservation overlays provide additional design layer.
