The United States District Court for the Eastern District of California is soliciting proposals for substance abuse, mental health, sex offender, and residential treatment services across multiple counties, including Shasta, Butte, El Dorado, Solano, Fresno, Kings, and Tulare. Vendors must have a physical site within the specified catchment area and be capable of providing all listed services, with subcontracting allowed under certain conditions. The agreement term is 12 months starting October 1, 2026, with the government having the option to unilaterally extend for up to four additional one-year periods. Vendors are not required to maintain a call-in phone system for urine collection, but all urinalysis samples must be sent to a designated laboratory in San Diego using pre-paid shipping labels. Performance of services must occur within the identified catchment areas, and proposals will be evaluated based on initial offers without opportunity for modification.
