Investment and Revitalization Strategy for Sacramento County Commercial Corridors

Solicitation # 2026-GEN-0073

Sacramento County is seeking to develop a comprehensive Investment and Revitalization Strategy for its 15 commercial corridors in the unincorporated areas, aiming to address longstanding challenges such as aging infrastructure, underutilized properties, fragmented ownership, and declining private investment. With a population of approximately 1.6 million and a diverse economy anchored by government, healthcare, logistics, education, and emerging sectors like clean technology and life sciences, the County has identified these commercial corridors as vital to economic vitality, community resilience, and long-term fiscal sustainability. Previous planning efforts—including market analyses and strategic reports from 2017 through 2024—have underscored the need for place-based, implementation-focused interventions that integrate housing, retail, public space improvements, and business support to attract private capital and revitalize underperforming districts. This initiative builds on those foundations to create an actionable roadmap that prioritizes opportunities, evaluates barriers, and aligns public resources to maximize impact across varied market conditions. The County is soliciting proposals through solicitation number 2026-GEN-0073, with responses due by September 5, 2026, and the work will be led by the Office of Economic Development based in Sacramento. The selected contractor will be tasked with delivering a practical, data-informed strategy that identifies realistic redevelopment opportunities, outlines prioritized actions for County intervention, and provides a clear framework for leveraging both public and private investment. Emphasis will be placed on strategies that enhance neighborhood-serving businesses, improve the physical environment, expand housing options, and foster equitable economic growth. The project will rely on existing background materials, including market studies and corridor maps, and is designed to ensure that revitalization efforts are tailored to the unique context of each corridor while contributing to broader regional goals. The final strategy must be executable, measurable, and designed to support sustainable fiscal outcomes for the County’s unincorporated communities.
