Guam Hazard Mitigation Plan - Western States Seismic Policy Council

SECTIONSIXMitigation StrategyTable 6–2Potential Mitigation ActionsAction No.Descriptionstorms and/or typhoons.23 Design and construct stormwater drainage facilities in the Calvo Industrial Park.24Harden or brace the Massey building in order to protect the integrity and structure of the butlerstyle warehouse facility.25Upgrade the stormwater drainage system at Harmon Industrial Park in order to resolvedocumented flooding problems.26 Install typhoon shutters on the GALC Tiyan buildings used by Public Health and GEPA.27 Elevate buildings at the Port located in Zone A as depicted on 2007 FIRM.28 Install stormwater outfalls at the Port.29 Install typhoon shutters on new or existing PAG buildings.Train personnel to achieve Wildland fighter type I & II certification, Wildland fire officer I initial30 attack incident commander. Wildland officer II Incident Commander, extended attack taskforce/strike team leader.Expand/Improve the network of available rain gauges and river gauges in order to enable31improved mitigation against erosion. There is a need for 10 additional rain gauges and 5additional stream gauges. These gauges should have both data-logging and real-time telemetrycapability.Install a wave-rider ocean wave buoy in southwestern Guam off-shore waters to mitigate against32coastal erosion. The existing ocean wave buoy off Ipan Talofofo cannot detect waves on the westside of Guam, and a similar buoy planned for northwest Guam will not be able to detect the mostcritical waves affecting the Agat to Merizo area due to blockage by Orote Point.33Install typhoon shutters and appropriately protected roll-up doors on all emergency servicesbuildings such as fire and police stations not equipped with these features.34Acquire, retrofit, and install back-up power and water systems for all emergency servicesbuildings such as fire and police stations not equipped with these features.Remove the large storefront windows located at the Front Courtyard Areas of the Hospital along35 the 1 st and 2 nd floor main corridors in order to limit water seepage during heavy rains and tropicalcyclones that causes slippery, unsafe condition in the 1 st and 2 nd floor main corridors.36Install typhoon shutters in the Skilled Nursing Unit (SNU) in Barrigada in order to mitigateagainst tropical cyclones.37 Evaluate all DOE buildings for seismic safety & retrofit.Identify and demolish DOE wood & tin classroom structures that pose a safety threat to students38and staff.Identify and mitigate schools that are susceptible to landslides such as FQ Sanchez Elementary in39Umatac.Identify, remove and dispose of abandoned A/C package units and related debris that pose40windblown hazards.Identify and upgrade rooftop electrical junction boxes to stainless steel, weatherproof, NEMA41rated to mitigate currently exposed electrical wiring.Replace/retrofit roofing from butler tin to concrete at the Cafeteria/Main Office buildings (642each) located at Machanaonao, AsTumbo & Ordot/CP Elementary Schools.Provide a redundant Energy Management System to monitor and control the island wide power43system. This will protect against cyber threats as well as physical damage.44 Protect electrical infrastructure along coastal areas from erosion.Mitigate the hazard and risk of the property on Block 24 and other flood-prone properties through45elevation and flood proofing or other minor flood control management efforts.6-21
