This RFP is to procure site-based supportive housing case management services for Clackamas Apartments, located at 15125 SE 90th Ave, Clackamas, OR 97015. The program resulting from this RFP will provide supportive housing case management services to residents in 20 units of affordable housing at Clackamas Apartments that serve households with a severe and persistent mental illness who are at or below 50% of Area Median Income (AMI). The primary aim of this initiative is to provide assistance to households that have secured permanent housing and express a need for, or desire to receive, supportive services to enhance housing stability. If households are already receiving housing support through alternative programs, they may be referred to this specific program for continuous case management services. It's important to note that this program covers the expenses associated with case management and other supportive services, and providers delivering these services may not be tasked with administering or providing rent subsidies for the participating households. The case management services offered are committed to ensuring participants sustain permanent housing over the long term, either through ongoing housing subsidy and support or by successfully transitioning away from rental subsidy and/or intensive case management support (referred to as "graduating"). Budgets for this program should comprehensively encompass all related expenses, including staffing costs and adequate flexible funds to meet the outlined program outcomes. Supportive housing, as conceptualized in this program, combines affordable housing with adaptable, tenant-driven, non-time-limited, and voluntary case management services. The overarching goal is to assist households experiencing homelessness in achieving housing stability
