<br />Memorandum to Dennis Trooien, Dennis Properties <br />Subject: Traffic Study for Proposed Redevelopmcnt of Arden Plaza <br />Page 2 of 6 <br />June 29, 2007 <br /> <br />RESPONSES TO TRAFFIC QUESTIONS <br /> <br />Chan!!es in Trip Generation due to Proposed Redevelopment (question a) <br /> <br />To determine how the proposcd redcvelopmcnt would affect thc total trip generation for the site <br />during the a.m. peak hour, p.m. peak hour, and on a daily basis, the following approach was <br />used: <br /> <br />1) We completed traffic counts at the driveway interscctions on County Road E and <br />Lexington A venue on a typical weekday during the p.m. pcak period. Using those traffic <br />counts, we determined the existing total p.m. peak hour trip generation for the site. <br /> <br />2) Since the proposed redevelopment involves removal of the existing office buildings, it is <br />important to divide the total trip generation for the site between retail and office. To <br />detcrmine what portion of thc existing trip generation is due to the office and what <br />portion is due to retail, we developed trip generation estimates for the existing uscs based <br />on data presented in the Institute of Transportation Engincers' (lTE) Trip Generation, <br />Seventh Edition. Based on the relationship between the estimated office and retail trips, <br />we divided the existing trip generation for the site between retail and office. <br /> <br />3) As describcd earlier, there presently is some vacant space both in the office and retail <br />buildings. To detcrmine the true change in trip gcneration for the sitc due to the proposcd <br />redevelopment, it is important to calculate the total trip generation for thc site with <br />existing uses fully occupied. Thus, the existing retail and office trips from step 2 were <br />increased by a ratio of tOlal square feet to occupied square feet. The resultant trip <br />generation from this stcp is the total trip generation for the sitc with full occupancy of thc <br />existing uses. <br /> <br />4) Trip generation for the proposed new retail uses was estimatcd based on data presented in <br />rTE Trip Generalion. <br /> <br />5) We removed trips due to the existing office buildings from the total trip generation for <br />the site with full occupancy of existing uses. We then added trip generation for the new <br />retail uses from step 4 to determine total trip generation for the site upon completion of <br />the proposed redevelopment. <br /> <br />6) Trip generation for the a.m. peak hour and on a daily basis was cstimated using the p.m. <br />peak hour counts and based on the relationship between p.m. peak hour and a.m. peak <br />hour and daily trip generation as per ITE data. <br /> <br />Table I shows a comparison of the trip generation for existing uses with full occupancy and upon <br />completion of the proposed redevelopment. As indicated in Table r, the proposed <br />
