The MX-3 district is intended to provide opportunities for office, commercial, institutional, and residential uses to support active modes of transportation. This zoning district will require transit- and pathway-oriented development organized along the City’s best-in-class transit routes and pathways at a scale designed to support the city’s transportation goals and investments and serve community needs broader than those of nearby neighborhoods. This zoning district may be expanded as new investments in Best-in-Class Transit Routes and pathways are developed.
