Hazardous Mitigation Plan


Concord’s Natural Hazard Mitigation Plan (NHMP) update focuses on actions to assist the community, public and private sector organizations, and others interested in reducing the impact of natural disasters on the community. The NHMP includes activities that may assist the City of Concord in reducing risk and preventing loss from future natural hazard events.

The Disaster Mitigation Act of 2000 (Public Law 106-390) was passed by Congress on October 30, 2000. The act required local jurisdictions to have a disaster mitigation plan in order to obtain either Pre-Disaster Mitigation (PDM) or Hazard Mitigation Grant Program (HMPG) funds.

The initial Concord Natural Hazard Mitigation plan was the culmination of several years of work by the Concord Division of Emergency Management and the Concord Emergency Planning Committee. That plan reflected the commitment of those whose energy created it, and is a testament to the City’s commitment to make Concord a more enjoyable place to work, live, and play.

A natural hazard mitigation plan addresses hazards that are considered part of the natural environment of Concord. It does not include manmade hazards (such as hazardous materials or HazMat incidents) except for dam failures and wildland/urban interface fires, which can have natural or manmade triggers.

Traditionally, many of the hazards are considered independently. However, the 2010 plan update featured some consolidation. For example, snowstorms and ice storms were considered as winter weather and tornadoes, windstorms, and severe thunderstorms were all combined into a single category:  severe weather. Several hazards were ruled out due to no local potential such as volcanoes, coastal storms, and tsunamis. Because of the extensive research conducted over the past few years into the effects of climate change, the decision was made to provisionally include it in the Plan, but without attempting to address mitigation measures related to it. As more is understood about the consequences for Concord, mitigation measures may be included in future editions of the Plan.

Since the adoption of the 2004 mitigation plan, some but not all of the hazards have had some level of impact on the City. Examples include a minor earthquake in October 2009 and the flood of August 2008, which resulted in a State Disaster Declaration. The 2010 revision includes information taken from recent studies, research, and historical data.   The plan is a result of reviewing existing plans, public input, and survey results to develop strategies to minimize the potential impact of hazards in Concord.

Concord has implemented multiple programs and policies effective in minimizing the impacts of hazards, including: 

  • developing outreach activities such as the Community Emergency Response Team program, Ready Kids, and public education to enable Concord residents, businesses, and visitors to survive in-place for more than three days;
  • ensuring continuation of governmental operations and provision of vital services following a hazard event, such as generators at critical facilities, departmental continuation of operations planning, work from home options, and disaster employee child care;
  • documenting natural hazards to identify venerable structures and infrastructure, in order to evaluate retrofitting or other mitigation efforts;
  • investing resources in building more resilient transportation networks to mitigate against the loss of major transportation facilities in and around the City; and
  • implementing a stormwater management system and continuing to explore educational and warning methods to mitigate impacts from expected increases in incidences of urban flooding.

What is a Mitigation Plan?

A hazard mitigation plan directs the community's efforts of reducing the risks to people and property from natural disasters. As a community grows it develops new areas, in order to avoid risks from natural disasters this growth must be directed away from risky areas. The plan must address new growth and define methods of making current areas safer and better prepared to recovery when a natural disaster does strike. In other words increase the communities hazards resilience.
