City of San Dimas Local Hazard Mitigation Plan & General Plan Safety Element Update

Community Survey

The Federal Disaster Mitigation Act of 2000 (DMA 2000) requires a community to have an approved hazard mitigation plan to be eligible to apply for and receive certain Federal Emergency Management Agency (FEMA) hazard mitigation funds. Receipt of FEMA funding is critical to implementing identified hazard mitigation projects and programs.

The City of San Dimas is preparing a new Local Hazard Mitigation Plan (LHMP). The LHMP provides a framework for the community to reduce its vulnerability to the impacts of natural hazard events such as earthquakes, flooding, and wildfires. The purpose of mitigation planning is to identify actions that can be implemented over the long term to reduce risk and future losses when an emergency or disaster occurs. Mitigation plans form the foundation for a community's long-term strategy to reduce disaster losses as well as to reduce the potential of repeat cycles of disaster damage, reconstruction, and repeated damage.

In conjunction with preparation of a LHMP, the City is updating the General Plan Safety Element. The purpose of the Safety Element is to reduce potential risks to people, property, and economic loss from natural and human-caused hazards. The General Plan establishes goals, policies, and programs to guide public decision-making regarding safety considerations in planning and development.

As we prepare the LHMP and update the Safety Element, your participation is critical. Please complete this survey! Your input will help the Planning Team understand the community's concerns and will guide development of the LHMP and Safety Element Update. Please note this is not a scientific survey, but it will assist the Planning Team to better understand the community's perspective on hazards that could impact the City and identify opportunities to inform and help the community prepare and respond to those hazards.

The survey should take approximately 10-12 minutes to complete and is anonymous. Your information will be kept confidential. The results of the survey will be included within the LHMP. The survey is open until 5:00 P.M. on February 27, 2026.

Structure and Infrastructure Projects: Construct "brick and mortar" public infrastructure and building improvements to eliminate or reduce hazard threats, or to mitigate the impacts of hazards. Examples – seismic retrofits, drainage improvements.
Preparedness, Coordination and Response Actions: Ensure that a framework exists to facilitate and coordinate the administration and enforcement of planned activities. Integrate prevention/mitigation activities into all local community operations.
Education and Awareness Programs: Education and community outreach to raise awareness of overall or hazard-specific risk and generate support for individual or community-wide efforts to reduce risk. Examples – school programs, mailed information, etc.
Local Plans and Regulations: Integrate mitigation into local bylaws, ordinances, and regulations to protect vulnerable resources and reduce risk. Examples – development restrictions in flood zones, capital planning for mitigation projects, etc.
