Statewide Extreme Heat Ranking System (SEHRS) Mobile Application

The Office of Environmental Health Hazard Assessment (OEHHA), a division of the California Environmental Protection Agency (CalEPA), is seeking proposals to develop the CalHeatScore mobile application, a statewide extreme heat ranking system. The procurement involves creating a comprehensive mobile application that will provide real-time extreme heat warnings, cooling center locations, health and safety information, and emergency resources for California residents. Key deliverables include a multi-language platform with accessibility features for users with disabilities, integration with existing state emergency management systems, and compatibility with National Weather Service data. The solicitation is scheduled for release on September 15, 2025, with vendor responses due by October 30, 2025, and a pre-proposal conference planned for September 25, 2025. Vendor qualifications will include demonstrated experience in emergency management applications, multi-language support, data security, and the ability to handle high-traffic volumes during extreme weather events. Evaluation criteria will likely emphasize technical capabilities, system integration potential, user experience design, and comprehensive heat emergency communication strategies.

The procurement includes set-aside opportunities specifically targeting small businesses and disabled veteran business enterprises (DVBEs), with a 25% participation goal. The contract term is anticipated to be three years with two optional one-year extensions, funded through a combination of state general funds and federal emergency preparedness grants. The total estimated budget for the initial three-year period is $2.8 million, representing a significant investment in modernizing California's extreme heat response infrastructure. Current state systems suffer from fragmented communication channels, and this project aims to centralize and enhance emergency heat notification capabilities. Vendors will need to demonstrate robust data privacy compliance, seamless integration with existing technological ecosystems, and the capacity to develop a scalable, user-friendly mobile application that can effectively communicate critical heat-related safety information to diverse population groups across California.
