Guam Hazard Mitigation Plan - Western States Seismic Policy Council

SECTIONSIXMitigation StrategyTable 6-3Implementation StrategyActionNo.156Description Primary Estimated CostComprehensively inventory and update all EFMUTS at risk fromhazards in order to provide emergency responders with accurateinformation about critical facilities. Inventory information shouldinclude exact location, facility type, owner/operator,replacement/insured value, year built, primary structural system,secondary building system/redundancy, building material, roofmaterial/type, mitigation upgrades (e.g., shutters, seismic retrofit),potential secondary impacts due to failure, and prior disaster impacts.Elevate, retrofit, or otherwise protect bridges and road segments,especially those provide ingress and egress to essential facilities thatare susceptible to flooding, landslides, and earthquakes. Fund a studyto evaluate vulnerability of these facilities to tsunami events.Develop and implement a process for assessing the hazardvulnerability of school buildings and grounds designated as stormshelters. Upon completion of vulnerability assessment, retrofitbuildings and grounds by installing typhoon shutters or replacingwindows and doors. This project will mitigate against multiplehazards, including tropical cyclone, severe wind, and disease events.Potential FundingSourceEstimated TimeFrameBSP $200,000 HMGP/PDM 2 yearsDPW TBD HMGP/PDM OngoingGuam PublicSchool SystemTBD HMGP/PDM 3 years9 Stabilize telemetry systems for domestic water and sewer systems.
