Extreme Heat and Community Corrections

Introduction

When a person under supervision is expected to find housing after leaving a California prison, they must navigate a fragmented system of housing subsidies, transitional beds, and eligibility criteria while a corrections officer sets their curfew, approves residences, and can send them back to prison for a missed appointment. California reform strategies have depended on systems of community corrections to empty beds in carceral facilities; while living anywhere but a state prison likely reduces heat risk, these systems have not been examined for the heat exposure and vulnerability they may add.

As parole and probation caseloads have fallen and per-person supervision spending has risen in California (see Appendix A), the concentration of resources reflects a concentration of need. California’s Public Safety Realignment (AB 109, 2011) and Proposition 47 (2014) diverted non-serious, non-violent, non-sexual offenders out of the state system and into county supervision or out of the system entirely. For decarceration, this has been effective; since 2011, the reconviction rate for all felony offenders dropped from 30% to 22% (Bird et al., 2019). But the people who remain under supervision are disproportionately those with higher risk classifications, more intensive service needs, and greater vulnerability (Grattet et al., 2018), including to extreme heat.

County probation departments operate with a “hybrid” model in which officers provide social work support such as substance abuse counseling, mental health support, and employment and housing referrals alongside their surveillance and sanction authority (Skeem & Manchak, 2008; Grattet et al., 2018). A 2014 statewide survey found that supervisor expectations for social work tasks had risen since 2002, while expectations for enforcement had not declined (Grattet et al., 2018). Enforcement is implemented via supervision, often via electronic monitoring, and violations are used to impose control and physical restrictions (Davis, 2016; Gottschalk, 2011). Violations issued from these restrictive conditions can result in extended parole or returning to a carceral facility, and have been shown to contribute to increasing incarceration rates, longer terms, and racial disparities in jail (Kang-Brown, 2020). In the hybrid model, services are directed at criminogenic needs and the risk factors for recidivism; program outcomes track recidivism and sobriety and do not include metrics for overall well-being, job, or housing status (C-ROB, 2024; CDCR Office of Research, 2026).

This intersect asks whether supervision conditions create new heat exposure pathways that parole and probation agencies have not addressed, by examining whether the community supervision “hybrid” model includes climate emergency response as a social work responsibility. Neighborhood-level resilience depends on the services the hybrid model intends to deliver; investing in addiction recovery, mental health support, and housing stability strengthens social networks and reduces isolation, which increases a neighborhood’s capacity to respond to climate emergencies (Chandra et al., 2011).

This intersect conducts a gap assessment of extreme heat emergency policy across California’s state parole and three county probation departments and finds that none have developed emergency planning for community-supervised populations. Without explicit policy, every heat-related compliance decision defaults to individual officer discretion, which compounds the racially disparate outcomes documented in routine supervision and increases the likelihood of technical violations that return individuals to carceral facilities — and to a second layer of heat risk.

Methodology & Data Sources

This intersect establishes the extreme heat risk profile for community-supervised populations by applying the shared environmental risk framework to peer-reviewed literature on supervision constraints, housing instability, and health vulnerabilities. A policy gap assessment is then conducted using the five-question comparative framework developed by Henry & Wachtendorf (2023) to evaluate whether parole agencies account for disasters in their policies. The original framework assessed hurricane evacuation procedures across three state parole systems; here, the same five questions are applied to CDCR’s Division of Adult Parole Operations (DAPO) and three county probation departments (Los Angeles, San Bernardino, Fresno), narrowing the hazard from hurricanes to extreme heat. Findings are assessed against Critical Resistance’s abolitionist framework to center formerly incarcerated voices as a precondition for emergency protocol design.

State parole was included as a direct continuation of Intersect 2’s analysis of state carceral facilities, as CDCR is the managing department of both populations. CDCR’s DAPO policy governs state parole directly but does not regulate county probation departments. County probation operates under their own separate authorities, with the Board of State and Community Corrections (BSCC) setting minimum standards for local detention facilities under Title 15, but not for community supervision operations (BSCC, 2023). Three counties were selected from among those with the highest total probation populations and probation rates per 100,000 residents (2023 data), with a variety of heat exposure and availability of publicly accessible policy manuals (Table 2). Twelve documents total were downloaded and reviewed in March 2026.

Table 2. Agencies selected for analysis, with population, heat data, and policy document sources.

All documents were reviewed using five adapted questions as the assessment structure:

1. Does the supervision agency have an emergency preparedness or continuity of operations plan that addresses supervised persons, as opposed to employee or building safety only?
2. Is the supervision agency or community supervision population included in the state or county emergency management plan?
3. What are supervision employees required to do during a climate emergency?
4. What are supervised persons required to do during a climate emergency?
5. Are supervision restrictions modified or lifted during climate emergencies?

This analysis is limited to publicly available documents; non-public internal procedures may address emergency planning in ways not captured here. Los Angeles County’s Probation Department Policy Manual (2010) references a separate “Emergency Manual” that is not published online, and Fresno County’s Procedures Manual contains no emergency planning content. Sacramento County was considered due to its high probation population (12,653) and heat exposure (92.1 historic heat days) but was excluded because its probation department operations manual was no longer publicly accessible at the time of review. The Tehama County probation manual was reviewed but contained no emergency planning provisions. The county analysis covers three of California’s 58 counties, selected for high supervision populations and heat exposure rather than representativeness.

Extreme Heat Risk in Community Corrections

There is very little literature on extreme heat risk for those within the systems of parole and probation, in California or elsewhere.

Exposure

Supervision Constraints

The systems of parole and probation are based on mobility and travel restrictions as a form of punishment (Phelps, 2018); these restrictive conditions create specific heat exposure pathways. Many parolees work in the outdoor industries of agriculture, construction, and warehouse operations and are most frequently released to Central Valley and Inland Empire counties (Harris et al., 2024), regions with high heat exposure. Parolees must obtain agent approval to travel more than 50 miles from their residence, with no exception for emergency evacuation due to climate hazards (CDCR, 2026; Cal. Penal Code § 3067). These conditions are mediated by officer discretion, which produces racially disparate outcomes: probation officer recommendations contribute to more severe sentences for African Americans, and racial disparities in technical violations are amplified where officers have greater discretionary authority (Leiber et al., 2011; Saunders et al., 2021).

Housing Instability

Housing instability is both a direct consequence of incarceration and a primary driver of heat exposure for community-supervised populations. Federal and state housing policies adopted during the 1990s excluded people with conviction histories from public and private rental markets, with no evidence that these exclusionary policies improve safety; this discrimination limits access to housing even when suitable options can be identified (Kajeepeta, 2025; Lake, 2021; Taber et al., 2022; California Civil Rights Department, 2022). Formerly incarcerated individuals are nearly 10 times more likely to experience homelessness than the general population, and homelessness increases the likelihood of incarceration (Couloute, 2018; Cusack & Montgomery, 2017). In California, up to one-half of all people on parole in San Francisco and Los Angeles are experiencing homelessness at any given time, and approximately half of people experiencing homelessness statewide report a history of incarceration (CA Assembly Committee, 2022). Suitable post-release housing for medically complex and older formerly incarcerated individuals is especially limited (CCHCS, 2026). Housing vouchers are one of the few rental subsidies available to people with conviction histories, but affordable units are severely scarce and vouchers are restricted to the holder’s county of residence, preventing supervised individuals from searching beyond their county even when local options are exhausted (Augustine & Kushel, 2022). Housing instability increases heat exposure both directly, for those in low-quality housing or unhoused during extreme heat events, and cyclically, for those whose instability drives reincarceration into facilities where heat risk is concentrated.

Housing provides the foundation for accessing all other reentry services, including employment, behavioral health, and physical health (Fontaine & Biess, 2012). People on parole in California are seven times more likely to recidivate when homeless; in San Francisco, housing instability increased recidivism especially for people on probation for low-risk and low-severity offenses (CA Assembly Committee, 2022; Jacobs & Gottlieb, 2020). Program pilots in Los Angeles for permanent supportive housing showed that 92% of participants achieved housing stability over six months; of those housed, 56% did not recidivate to jail in a two-year period, compared to the CDCR baseline of less than 30% (Hunter, 2023). In a 2020 survey of currently incarcerated people, among the top answers for what could have kept them out of prison were access to affordable housing and living wages (Lewis et al., 2020). A lack of housing also directly increases heat risk; heat-related mortality associations for unhoused people are 10 to 100 times greater than for the general population (Lin et al., 2024). Major heat days were associated with a 59.3% increase in deaths among homeless individuals in Los Angeles County (Baker & Sturm, 2024).

Vulnerability

Populations who have gone through the carceral system have high rates of hypertension and cardiovascular disease, conditions in which heat exposure directly increases cardiac strain and mortality risk (AAFP, n.d.; Singh et al., 2024). Extreme heat days are associated with higher risk of substance use disorder emergency healthcare utilization (Jhang, 2025). Over 75% have an identified behavioral health need at release, and many are on medications for those needs (CDCR CCJBH, 2025); these medications increase heat-related illness risk, and individuals must comply strictly with medication adherence as a condition of parole regardless of temperatures. Within six months of release only 41.4% of individuals with serious mental illness maintain their prescriptions, primarily because they have unpredictable housing (Dague et al., 2025). Typically, age vulnerabilities for heat-related illness and death begin at age 65; however, those who are previously incarcerated have symptoms of “accelerated aging” and show statistically significant health impacts beginning at age 50 (Novisky, 2025). Re-entry planning routinely fails this aging population: common issues include delays in accessing health providers, interruptions in medication or treatment due to lost prescriptions or records, and difficulty navigating health systems post-release (CCHCS, 2026).

Social and physical isolation also increases heat vulnerability; during heatwaves, isolated individuals are less likely to be checked on or to be reached by emergency services (Klinenberg, 2002). Incarceration erodes the capacity to seek help and maintain social connections; past trauma among incarcerated populations is associated with lower perceived social support and higher loneliness (Kao et al., 2014), and the stigma of a criminal conviction compounds racial discrimination in access to employment, housing, and services (Beckett & Goldberg, 2022). Among people returning from prison, those with co-occurring addiction and mental illness had the weakest remaining support networks, the most unstable housing, and the lowest levels of employment (Western, 2018). Parole and probation often require maintaining employment, but previously incarcerated individuals are more likely to experience spatial mismatch and less access to transportation, making employment more difficult to acquire and maintain (Roddy, 2024; Bohmert, 2014).

These compounding vulnerabilities form a reinforcing cycle: incarceration produces increased heat vulnerability and unstable housing, job, and healthcare access; this instability and isolation increases heat exposure, which in turn further destabilizes housing and increases the chances of supervision violations; those violations could lead to returning to jail or prison where heat risk is much higher. For community-supervised populations, each stage of this cycle operates under supervision constraints that limit the individual’s capacity to intervene on their own behalf.

Emergency and Climate Policy Gap Assessment

Neither DAPO’s publicly available regulations nor any of the three county probation departments’ manuals contain policies or procedures addressing climate emergencies or extreme heat events for community-supervised populations (Table 3). Emergency planning for county probation departments falls to each county’s Office of Emergency Services or equivalent, and there is no state mandate requiring county probation to include community-supervised populations in emergency plans. This regulatory fragmentation means that responsibility for climate emergency planning for the community-supervised population is distributed across many independent agencies.

State Parole: DAPO Emergency Policy Assessment

The State DOM contains two articles addressing emergency preparedness for parole: § 11050 (“Evacuation and Emergency Management,” effective January 1990) and § 85090 (“Emergency Protection,” revised February 2018). Both are exclusively concerned with employee safety and building evacuation. Neither references supervised persons, and neither mentions extreme heat as a hazard type; § 11050 addresses fire, explosions, earthquakes, bomb threats, and nuclear threats, while § 85090.13 identifies earthquakes, fire, flood, and terrorism.

DAPO is also absent from the state’s broader emergency infrastructure. CDCR is listed as an Emergency Support Function agency in the California State Emergency Plan, but this role centers on institutional operations and incarcerated fire crews, not parole supervision (CalOES, 2023). The 2022 Extreme Heat Action Plan does not reference community corrections populations in any capacity (California Natural Resources Agency, 2022). No DOM provision addresses what parole agents or supervisees should do during heat emergencies; the conditions of parole (DOM § 81010) and Notice of Conditions contain no emergency exception clauses, and the only relocation mechanism (Transfer Investigation Request, § 81010.10) requires agent investigation, supervisor approval, and District Administrator authorization, a timeline incompatible with emergency conditions.

County Probation: Emergency Policy Assessment

The county-level analysis mirrors the state finding. Across the three counties, emergency planning is oriented toward facility operations and employee safety, not toward the populations supervised in the community. Los Angeles County’s probation manuals contain no community supervision emergency protocols; the AB 109 Manual on Post-Release Community Supervision contains zero references to extreme heat, wildfire, or climate (Los Angeles County Probation Department, 2023). Fresno County’s Procedures Manual is entirely silent on emergency planning for supervised populations (Fresno County Probation Department, 2026).

San Bernardino County is the only county with a manual that explicitly acknowledges the community-supervised population, in three sections: it identifies continuity of supervision as an organizational objective during emergencies, then later classifies community supervision as a “deferred (non-mandatory) function” that “should resume” after the emergency ends, and carves out exceptions for high-risk sex offender GPS monitoring and juvenile house arrest that must be maintained “if still functional” (San Bernardino County Probation Department, 2025). The plan’s preparedness provisions reference mutual aid agreements and coordination with county social service agencies, but the actions operationalize facility operations for detained juveniles; no preparedness action specifies communication protocols with community-supervised adults. The DEOP anticipates that supervised people will be “displaced or adversely affected by the disaster” but offers no protocol for locating, communicating with, or supporting them once displaced.

Table 3. Emergency policy gap assessment, applying the Henry & Wachtendorf (2023) framework to California’s state parole system (DAPO) and three county probation departments.

Impacts

Applying the Henry and Wachtendorf (2023) gap assessment framework to the California findings identifies four categories of impact on community-supervised populations during climate emergencies.

Disaster Preparedness

California follows the same pattern Henry and Wachtendorf (2023) found in Texas, Louisiana, and Florida: emergency plans focus exclusively on agency operations and staff, with the supervised population excluded. The county-level analysis confirms that this gap is structural across many scales of community corrections governance. San Bernardino County’s DEOP is the only document that explicitly acknowledges the supervised population, but it is internally contradictory: it simultaneously frames supervision as an organizational objective, classifies it as deferrable, and carves out qualified exceptions for GPS monitoring of high-risk individuals. The policy gap is not merely an absence of heat-specific guidance; it is the complete exclusion of supervised persons from emergency frameworks at both the state and county levels. The absence of planning is especially striking given that CDCR developed detailed heat protocols for its incarcerated population in response to Coleman v. Wilson (1995), but the moment an individual crosses from incarcerated to paroled status, every one of these protections disappears despite ongoing heat risk.

Undermining Self-Sufficiency

The gap assessment findings confirm that no agency has plans for supporting supervised individuals during climate emergencies. In San Bernardino, the DEOP references mutual aid agreements and coordination with county social services, but never operationalizes these provisions for community-supervised adults. The result is that the individuals whose mobility, housing, and employment are constrained by supervision conditions are given the most responsibility for their own safety during emergencies, when maintenance of support networks is critical for resiliency.

Exacerbating Social Vulnerability

The policy gaps identified in this assessment do not merely fail to address existing vulnerabilities; they actively deepen them during the emergencies when they are most dangerous. San Bernardino County’s DEOP provides the clearest illustration: the plan’s Heat Illness Prevention Plan and Wildfire Smoke Protection plan establish detailed protocols for protecting probation officers during heat and air quality events, but extend none of these protections to the people those officers supervise (San Bernardino County Probation Department, 2025). This creates a two-tier emergency response within the same agency, where the system acknowledges the hazard for its employees but not for the population it controls.

For a population whose incarceration experiences have diminished capacity to seek help and navigate unfamiliar systems (Kao et al., 2014; Haney, 2012), the loss of institutional contact during a crisis intensifies the isolation that makes them vulnerable. No county or state document reviewed establishes an emergency shelter placement mechanism for supervised individuals, meaning the heat-risk cycle documented in this intersect — increased heat vulnerability and unstable housing lead to greater heat exposure, which could lead to more incarceration — has no policy intervention point during an emergency. The deferral of supervision does not defer the conditions of supervision; mobility restrictions, reporting obligations, and employment requirements remain in effect as the agency steps back from responsibilities during an emergency.

Recidivism and Quality of Life

Without disaster-specific guidance, routine supervision conditions can conflict with self-protective behavior during heat emergencies. A supervised individual who travels outside their approved area to access a cooling center, stays at an unapproved address to escape heat, or misses a reporting appointment due to heat illness could face a technical violation, with the determination resting on individual officer discretion. This discretion produces racially disparate outcomes; the absence of explicit emergency policies means that every heat-related compliance decision defaults to the same discretionary authority that research has shown to be biased against people of color (Leiber et al., 2011; Saunders et al., 2021). No agency reviewed contains emergency exception clauses for supervision conditions or modification mechanisms for climate emergencies. Revocation for a heat-related technical violation returns an individual to prison or jail, exposing them to a second layer of heat risk within the carceral system.

Conclusions

California’s chronic and worsening heat hazard creates conditions in which the current systems of parole and probation become mechanisms that undermine self-sufficiency, exacerbate vulnerabilities, and could increase recidivism. Climate emergency response is entirely absent from the hybrid model of community corrections; supervision conditions that were designed without climate in mind now function as heat exposure mechanisms, and no agency reviewed has plans to address them. The interaction between supervision constraints and compound climate hazards has no precedent in the corrections policy literature and represents an area requiring both scholarly attention and policy response.

Limitations & Next Steps

This analysis is limited to policy gap assessment and literature review, and should be considered a first step in a larger research project. The county analysis is based on publicly available documents from three of California’s counties. Follow-up research should extend this framework to additional counties, request non-public policy documents, and incorporate interviews with supervisees and program employees about actual practices during heat events. Follow-up research should also include investigating a measurable relationship between extreme heat events and recidivism for those on parole or probation.

A potential policy response to these findings would be to require DAPO and county probation departments to develop emergency protocols for supervised populations. Both Critical Resistance’s framework and Sanders’ carceral humanism toolkit caution that emergency protocols developed by supervision agencies risk creating new reporting obligations, new conditions of supervision, and expanded surveillance. Follow-up research that informs specific strategies should be authored by individuals who have experienced or been impacted by the systems of parole and probation in California; the people most affected by a system hold experiential knowledge that institutional research cannot replicate, and centering this knowledge is a precondition for policy that serves rather than surveils those communities (Jolivétte, 2025). The goal is not to make community corrections more comprehensive but to ensure that climate emergency response for this population supports successful re-entry and improved quality of life.

The work of rebuilding social connections, stabilizing housing, and restoring health after incarceration is the same work that builds community capacity to increase resilience to climate emergencies. The community-based organizations building resilience hubs in Intersect 1 offer a model for what this integration can look like when it is led by the communities most affected. Supervised individuals returning to heat-exposed neighborhoods need stable housing, healthcare continuity, and the social capital of community; resilience hubs are already building that capacity to support climate adaptation and decarceration.
