Guam Hazard Mitigation Plan - Western States Seismic Policy Council

SECTIONFOURIsland Description- Bus stations- Major roadsValues for the EFMUTS were collected from a wide variety of sources, including the following:the Government of Guam agencies that own, operate, and/or insure or maintain the facilities; theGuam Department of Revenue and Taxation; and HAZUS.A total of 850 EFMUTS worth over $1.90 billion were identified and mapped. The following is abreakdown of these EFMUTS by major category of Critical Buildings, Facilities, andInfrastructure:• 355 Essential Facilities worth $906.03 million (an increase of 66 Essential Facilities from the2008 Guam HMP). Additional Essential Facilities added to the 2011 Guam HMP includerecreational facilities (softball and baseball fields, tennis courts, etc.) and additions to mostother categories, such as newly opened schools and fire stations.• 362 Major Utilities worth $884.86 million (an increase of 68 Major Utilities from the 2008Guam HMP). Major Utilities added to the 2011 Guam HMP include a larger number ofpotable water and wastewater assets.• 133 Transportation Systems worth $112.71 million, including 23 major roads totaling 133miles and worth $1.9 million (an increase of 53 assets from the 2008 Guam HMP).Transportation Systems added to the 2011 Guam HMP include additional traffic signals andpedestrian crossing signals as well as additional bridges.The EFMUTS are listed in Tables E-1, E-2, E-3, and E-4 (Appendix E [Essential Facilities,Major Utilities, and Transportation Systems]) and are shown on Figures D-6 through D-11.These facilities and related data have been mapped using GIS and form the basis for thevulnerability and potential loss estimates.4.9 PLANNING AND DEVELOPMENT4.9.1 General BuildupGuam’s General Building Stock (GBS), which includes both residential and nonresidentialstructures (non-EFMUTS), was identified and mapped as 40,069 buildings. For the updated 2011HMP, no new data on building stock were available. With 2010 property tax information, valueswere obtained for the average assessed building value (in $/building) for each village. Theaverage building values for Guam’s GBS varied from a low of $65,548/building in Umatac to ahigh of $412,678/building in Tamuning. The average value of a building (residential andnonresidential) in Guam is $133,946. Earlier versions of the Guam HMP used an average valueper square foot of building space, by village, to estimate the value of the GBS. However, theaverage value per square foot of building space for each village was not available for the 2011Guam HMP, which is why the average building value was used to estimate the value of the GBS.As shown on Figure D-12 and listed by village in Tables F-1 and F-2 in Appendix F(Vulnerability and Potential Loss Results by Village), the highest numbers of buildings, indescending order, are found in the villages of Dededo, Yigo, and Tamuning. The highestconcentrations of building values, in descending order, are found in the villages of Dededo,Tamuning, and Yigo.4-12
