Mitigation Planning Process

Why Have a Mitigation Plan? Provides Risk Analysis Identify hazards that pose a threat Potential loss risk Serves as the gateway to 5 major mitigation grant programs.

Harris County Mitigation Plan Harris County All-Hazard Mitigation Plan FEMA Approved: August 19, 2010 Multi-Jurisdictional Plan (34 Jurisdictions Total) 28 Municipalities 4 Special Jurisdictions Brought over $317 million to Harris County and participating jurisdictions since the year 2000

Timelines Project Timeline Started:June 4, 2009 Completed:February 21, 2011 Duration:448 Workdays Risk Analysis Timeline Started:September 2, 2009 Completed:November 18, 2009 Duration:56 Workdays

Harris County Community Profile 1777 Square Miles 4+ Million People 1.5+ Million Households 3 rd Largest County by Pop 34 Cities 22 Major Watersheds 8800 Miles of Pipeline Over 1200 MUD/PUDs 35 Presidential Declarations of Disaster

Risk Assessment Hazard Profiling Hazard Identification Hazard Analysis Loss Estimation NFIP Requirements Risk Assessment Hazard Profiling Loss Est NFIP Req

FEMA Crosswalk Requirements Risk Assessment Hazard Profiling Loss Est NFIP Req Hazard Profile Hazard Identification Identify the hazards with potential Identify how the hazards are measured or quantified. Hazard Analysis Identify the hazard area at risk Extent of risk (magnitude/severity) Provide historical occurrence data and damage summaries Loss/Vulnerability Identify probability of future events Summarize the vulnerability to each hazard Address impact of each hazard NFIP Requirements Identify types and numbers of repetitive loss properties Describe participation in NFIP Identify, analyze, and prioritize NFIP related mitigation action items

Hazard Identification Where can you go to identify hazards? State Mitigation Plan Local Basic Plan (EAP/EOP) Internet National Weather Service Libraries Floodplain Managers Past Events Mitigation plan currently focuses only on natural hazards Risk Assessment Hazard Profiling Loss Est NFIP Req

Harris County Hazard Analysis EM Survey Focused on “Perceived Risk” among area emergency management professionals. Risk Assessment Hazard Profiling Loss Est NFIP Req

Harris County Hazard Analysis Risk Assessment Hazard Profiling Loss Est NFIP Req Severity of Impact ScoreCriterion 1Limited  Injuries and/or illnesses are treatable with first aid.  Minor quality of life lost.  Shutdown of critical facilities and services for 24 hours or less.  Less than 10 percent of property within the region destroyed or with major damage. 2Minor  Injuries and/or illnesses do not result in permanent disability.  Complete shutdown of critical facilities for more than 1 week.  More than 10 percent of property within the region destroyed or with major damage. 3Major  Injuries and/or illnesses result in permanent disability.  Complete shutdown of critical facilities for at least 2 weeks.  More than 25 percent of property within the region destroyed or with major damage. 4Substantial  Multiple deaths  Complete shutdown of facilities for 30 days or more.  More than 50 percent of property within the region destroyed or with major damage.

National Standard for Loss Estimation GIS Intensive Limited Computer Specifications (SP3, Win7, Etc.) Census Based Data Addresses limited hazards Not designed for “out of box” use A nationally applicable standardized methodology that estimates potential losses from earthquakes, hurricane winds, and floods (FEMA, 2010). Hazards Addressed:  Flooding  Hurricanes  Earthquakes Risk Assessment Hazard Profiling Loss Est NFIP Req
