All Hazards Planning

Horsley Witten Group works with clients in both the government and private sectors to develop refine and update emergency preparedness and response plans. By working closely with clients and their response partners, we ensure that plans will aid agencies and jurisdictions in preparing for, mitigating against, responding to and recovering from both natural and man-made disasters.






Hazard Mitigation Planning

Hazard mitigation is the effort to reduce loss of life and property by lessening the impact of disasters. We work with clients to develop community-specific hazard mitigation plans to qualify for FEMA grant funding, as well as with government agencies to develop national hazard mitigation planning guidance.







HSEEP Exercises

We follow the Homeland Security Exercise and Evaluation Program (HSEEP) methodology as the basis for developing and conducting emergency response exercises. The firm designs both discussion-based and operations-based exercises, working with an exercise planning team of local stakeholders. Exercises are objective-based and our staff creates the”story” that allow participants to discuss and practice targeted capabilities of their response and/or recovery procedures and plans. 



The Horsley Witten team of experienced emergency preparedness planners are actively supporting COVID-19 response remotely in our nation’s capital by working with the District of Columbia Water and Sewer Authority (DC Water) Incident Management Team. Read more…

Specialty Workshops & Training for Critical Infrastructure and Key Resources
