The basis for this estimate is from a traffic study presented in the 2005 Self-Storage Almanac. The study is updated annually and is for the purpose of advising storage designers how to estimate parking requirements. (See excerpt attached) This study states "As seen in Table 7.1, an average facility may draw 20 vehicles per day. However, this number vanes depending on whether the facility is located in a heavy industrial area versus a rural setting, or the size of the facility is less than 25,000sq.ft. or more than 100,000." The study has further broken down the expected traffic draw by 5 independent variables: Region, Number of Units, Rentable Square Feet, Market Area & Population of Surrounding Area. I have today customized this data, using graphs where appropriate, to more closely estimate the expected daily visits for this facility. The assumptions and results are as follows: Region Pacific 19.5 per day Number of Units 540 30.0 Rentable Square Footage 56,000 27.0 Market Area Rural 13.9 Population of Surrounding Area 35,000 16.8 Average Daily Visits 21.4 As a further check, I have obtained the actual trip count for the A-American facilities in Hawaii for the month of January 2007. (See attached analysis) I have added two columns for Average Unit Size and Daily Trips fora 540 unit facility. After excluding the atypical Kihei (mixed commercial tenants) and the Lipoa (in rent up phase) facilities, the average trip count is 19.87 vehicles per day. Comm. No. S ~ 8 R®f. To: heass+t~e Ref.
