California's SB 1248 compliance requirements require districts to address excessive precipitation and flooding, but the same best practices can help schools anywhere develop safer, more consistent weather procedures. Although most of California's rainfall occurs during the winter months, it coincides with the school year and can significantly impact daily operations. Heavy rain and flooding can disrupt school activities just as quickly as extreme heat. Under SB 1248, California school districts, county offices of education, and charter schools must include excessive precipitation and flooding in their extreme weather protocols. In areas prone to flash flooding, districts should also consider procedures for rapidly changing conditions. Clear procedures protect students, keep staff aligned, and support the documentation needed for compliance.
Heavy rain reduces visibility, creates slippery surfaces, and can overwhelm drainage systems on campus. Flooding may block access roads, inundate playgrounds or athletic fields, and force early dismissals or shelter-in-place decisions. Even moderate rainfall can make outdoor physical education, recess, and after-school activities unsafe. Inland and coastal districts face different risks: rapid runoff in urban areas, flash flooding in canyons or low-lying zones, and prolonged saturation that affects fields and walkways for days.
Following a wildfire, burned hillsides are far more susceptible to debris flows and mudslides during heavy rain. Schools located near burn scars may need additional procedures because hazardous conditions can develop much more quickly than during a typical rain event.
SB 1248 requires every local educational agency to develop a written protocol that addresses extreme weather conditions capable of harming students during outdoor activities. The California Department of Education’s standardized guidelines explicitly include excessive precipitation and flash flooding alongside heat and air quality. The law applies to all outdoor activities across grade levels, not only interscholastic athletics. Districts must define thresholds, response actions, monitoring methods, communication steps, and recordkeeping for these hazards just as they do for heat.
Write progressive actions that match different levels of risk. Examples include:
Identify indoor alternative activities in advance and name the staff authorized to make each decision. Procedures should be simple enough for teachers, recess monitors, and site administrators to follow without delay.
Regional forecasts provide useful advance notice, but conditions on a specific campus can differ significantly from the nearest official station. Local topography, drainage capacity, and nearby waterways influence how quickly water accumulates. Even schools only a few miles apart may experience different rainfall rates because of terrain, elevation, and localized thunderstorms. Look at the following data from our stations in Ventura County where just a few miles of distance made a big difference in rain rates:
On-site monitoring of rainfall rate and accumulation, combined with awareness of flood watches, warnings, and local stream gauges, gives staff the real-time information needed to act. Pair automated alerts with clear thresholds so decisions do not rely on individual judgment alone. Maintain timestamped records of conditions and actions for annual review and liability protection.
Heavy rain and flash flooding often require rapid, multi-channel communication. Define how decisions reach teachers and outdoor supervisors, how families are notified of schedule changes or early dismissals, and how transportation staff receive updates about road conditions.
Include backup methods in case of power or network interruptions. Consistent messaging reduces confusion and helps families plan. Document every significant notification as part of the protocol’s record-keeping requirements.
Excessive precipitation and flooding are explicit parts of SB 1248 compliance. Districts that define clear thresholds, assign decision-making roles, monitor conditions in real time, and communicate promptly create safer campuses and stronger documentation.
Review your current protocol against these elements, close any gaps, and practice the procedures with staff. Prepared, consistent responses keep students safe when heavy rain arrives.

Does SB 1248 require California schools to address heavy rain and flooding? Yes. The California Department of Education's standardized guidance, which LEAs must incorporate into their SB 1248 protocols, includes excessive precipitation and flooding alongside heat and air quality.
What should a rain and flood response procedure include? Clear thresholds, progressive actions (shorten, relocate, cancel), indoor alternatives, named decision-makers, and communication steps for staff and families. Procedures should be simple enough for non-experts to follow quickly.
Why is on-site monitoring important for heavy rain at schools? Campus conditions can differ from regional forecasts due to local topography and drainage. On-site rainfall data and automated alerts support faster, more consistent decisions and create the timestamped records needed for compliance.
