Findings 11 findings

F1
The San Mateo County men’s jail has been overcrowded each year since 2001. Over the last ten years, incarcerated populations have ranged from 120% of bed-rated capacity in 2002 to 147% in 2007.21
F2
From 2002 through 2007, 50 percent of the average daily population of the San Mateo County men’s jail facility consisted of pre-trial detainees (PTDs); since 2007, the pre- trial detainee (PTD) average daily population percentage has steadily increased to 76 percent in 2011.
F3
San Mateo County has zero (0) pre-trial detainees on an Electronic Monitoring Program (EMP) and nine (9) pre-sentenced/sentenced detainees on an EMP.
F4
The Grand Jury found that significant daily cost savings of approximately $100 per inmate/per day is available if selected pre-trial detainees are released into an EMP.
F5
Currently, there is a risk assessment tool in use to determine eligibility for EMP with pre-sentenced/sentenced detainees. This risk assessment tool is not used with pre-trial detainees. Sheriff’s Office Information: San Mateo County Sentenced vs. Pretrial in Custody Inmate Population Percentage. 8
F6
Based on the U.S. Department of Justice adult male arrest data provided by the San Mateo County Sheriff’s Office, the violent crime index in the county has remained relatively stable from 2001-2009.
F7
According to information gathered from interviews conducted by the Grand Jury, the reasons for the increase in the pre-trial detainee male jail population (compared to pre- sentenced/sentenced detainees) in recent years are due to two main factors: • The types of charges that detainees increasingly face (immigration holds, gang affiliation, violent crimes, sex crimes, DUIs, outstanding warrants) are offenses that eliminate eligibility for any form of release. • To comply with the Corrections Standards Authority (CSA), in 2008 the Sheriff’s Office changed its classification system for parole holds and others with pending cases or warrants from sentenced to pre-trial. This increased the pre-trial detainee population by 10-15%.22
F8
The statistics reported by the U.S. Department of Statistics, Bureau of Justice Statistics (see, Appendix B) from data provided by the San Mateo County Sheriff’s Office do not support the first factor listed in Finding #7.23
F9
The Sheriff’s Office and the Probation Department have not budgeted for studying or implementing an EMP for pre-trial detainees.
F10
Elsewhere EMPs for PTDs have been implemented to varying degrees: • Santa Cruz and Santa Clara have purchased their own ankle bracelets and related equipment. • Santa Cruz and Sacramento have an active budget for EMP expansion and Pre- trial Services. • Santa Clara has one PTD on EMP; Santa Cruz has 25 PTDs on EMP; and Sacramento’s EMP program for PTDs begins May 2012. • Santa Cruz is a member of the California Association of Pretrial Services (CAPS) and uses the Virginia Assessment tool to determine eligibility of PTDs for EMP. • San Mateo County spends $7-10 (not including monitoring, supervision costs) per day on EMP for pre-sentenced/sentenced detainees versus a $169 daily incarceration cost.
