The purpose of the urban residential zone is to reinforce the City’s planned concentration of pedestrian-oriented mixed use residential development at intensities that support and are supported by multi-modal transportation options, including high capacity transit. The urban residential zone provides opportunities for a mix of jobs and high-density residences, cultivates a respectful relationship among development within the area, the natural environment, and nearby traditional neighborhoods, and provides a framework for future infrastructure and service decisions. The urban residential zone provides public benefits in the form of affordable housing, increased pedestrian connectivity, quality design, and incentives to preserve significant tree groves where they exist.
