About this file
This is a development planning document prepared for the City of Santa Cruz, California, detailing buildout assumptions and development metrics for the Downtown Plan Expansion project adopted in May 2025. The document presents a baseline scenario with a 3.5 Floor Area Ratio (FAR) that includes an arena and establishes development parameters across ten blocks (designated Factors A through J) within the downtown expansion area. The project encompasses a total gross floor area of 1,430,718 square feet, comprising 1,116 residential units and 54,100 square feet of commercial space, supported by 1,251 parking spaces. Individual blocks vary significantly in scale, from Factor G at 4,829 square feet (15 units) to Factor C at 111,723 square feet (313 units), with zoning designations including CBD-E (Central Business District-East) and R-H/RM (High-Density and Medium-Density Residential). Each block establishes specific development assumptions including density metrics (ranging from 40 to 55 units per acre), parking efficiency ratios, residential efficiency factors, and ground floor commercial percentages, all designed to support the City's infrastructure planning and impact fee analysis.
The document serves as the foundational input for the City of Santa Cruz's Nexus Study and Development Impact Fee analysis, which is being prepared in compliance with California's Mitigation Fee Act (AB 1600, Government Code Sections 66000-66025). The buildout assumptions and order-of-magnitude infrastructure cost estimates provided in this document will be reviewed, validated, and updated by the selected consultant to establish appropriate development impact fee rates that demonstrate the nexus between the proposed developments and their impacts on city infrastructure. These planning parameters establish the baseline metrics against which infrastructure requirements, costs, and corresponding impact fees will be calculated to support the City's fiscal planning for the Downtown Plan Expansion area.
