Guam Hazard Mitigation Plan - Western States Seismic Policy Council

SECTIONFOURIsland DescriptionThis GBS has been mapped using GIS and has formed the basis for the vulnerability andpotential loss estimates. However, additional information that would have contributedconsiderably to the vulnerability and potential loss analysis was simply not comprehensivelyavailable for the GBS for this update with the time and resources available. Useful informationfor future plan updates would include the type of building (e.g., residential, commercial,industrial, governmental); age/year built; primary building material; roofing material; generalcondition; mitigation upgrades (e.g., seismic retrofit, wind shutters); and prior hazard damage.A method of determining the level of growth in the GBS is through an analysis of buildingpermits. Table 4-7 shows the numbers of new building permits issued, the total values of thesebuildings, the number of permits issued for additions to buildings, and the values of thesebuilding additions for the years 2000 through 2010. These values do not include any newbuildings and additions to existing buildings that were constructed without a building permit.From 2000 to 2010, the largest number of building permits (for both new structures andadditions) were issued in 2000.Table 4-7 Building Permits Issued by Year, 2000–2010Fiscal Year Number (New) Value ($) Number (Additions) Value ($)2000 428 $64,385,684 228 $43,010,4122001 277 $55,883,125 229 $30,344,6952002 211 $25,617,000 206 $24,677,0002003 407 $43,852,733 759 $52,188,5232004 266 $46,524,605.41 391 $31,112,4232005 290 $54,521,457 252 $32,288,1132006 329 $85,383,295 234 $36,971,3472007 373 $160,096,000 247 $25,807,0002008 383 $121,840,000 277 $20,835,0002009 274 $138,662,000 225 $13,050,0002010 386 $80,501,000 196 $11,157,000Note: Values do not include government, demolition, relocation, grading, signing, miscellaneous, or renewal permits.Source: DPW 2011.Table 4-8 shows the number of building permits issued by village on Guam in 2010. Thesequantities indicate the villages where large amounts of construction are occurring. In Yigo, 72permits (19 percent of the total number of permits) were issued for new construction in 2010, thehighest number in Guam. The village with the second-highest number of permits issued for newconstruction in 2010 was Dededo, where 60 permits (16 percent) were issued for newconstruction. In 2010, the largest number of permits issued for additions to existing structureswas issued in Tamuning, with 48 such permits (24 percent) issued. Tamuning is followed byDededo, where 46 permits (23 percent) were issued for additions.4-13
