Zoning Reform and Code Writing

The city's zoning code includes a mix of use-based and form-based zoning standards. It defines and regulates uses based on broad categories, with select specific use types, and includes use-specific standards to minimize reliance on discretionary use permits. And it includes building form standards for each district. It is richly illustrated and uses tables to organize use permissions and dimensional standards.

Its general intent statements address balancing conservation and development; achieving design excellence; and guiding the city’s prosperous and sustainable future (§1.1.2).
