-� <br />Mr. Jeffrey Agnes <br />0 <br />September 12, 2007 <br />accomplished by applying typical trip generation rates to these uses and then assigning the <br />resultant trips through the three subject intersections according to expected routes of travel. <br />In progressing from the 2009 no-build condition to the 2009 build condition, we accounted for <br />the following two factors: <br />a) Replacement of all former uses with the new proposed uses. This involved <br />accounting for the incremental increase in trip generation as will be quantified later. <br />b) Closure of the existing right turn in and out only access on County Road B. Though <br />this action is not part of the current plan, a need exists to account for this change, <br />because it may occur in the future. <br />For the weekday p.m. peak hour, the gross trip generation for the former and proposed uses is <br />shown in Table 1. For this purpose, it is important to point out that a conservative approach has <br />been taken to estimating trip generation for the proposed uses in spaces 81 A, 81 B, and 81 C. The <br />current plan is for 81A (3,300 square feet) to be occupied by a sit-down restaurant, and spaces <br />81 B and S 1 C(total of 3,300 square feet) to be occupied by general retail uses. To be <br />conservative, we have applied the sit-down restaurant trip generation rate for a116,600 square <br />feet in these three spaces. For the Saturday mid-day peak hour, the corresponding gross trip <br />generation for the former and proposed uses is shown in Table 2. <br />As mentioned above, the 2009 build volumes account for the incremental increase in trip <br />generation for the proposed uses. The incremental increase in gross trips is shown in Tables 1 <br />and 2. This change also is shown in Table 3, together with differences in net total trips, net new <br />trips, and net pass-by trips. Beyond the incremental changes in gross trips, the changes in the <br />other trip categories shown in Table 3 are described as follows: <br />a) Net total trips. The difference in net total trips is iive percent lower than the <br />difference in gross trips to account for multi-purpose trips that will be within the Har <br />Mar Shopping Center development. <br />b) Allocation of net trips between new trips and pass-by trips. Based on data published <br />by the Institute of Transportation Engineers, we have estimated that 70% of the net <br />trips generated by retail uses will be new trips, and 30% will be pass-by trips. These <br />percentages apply both the weekday p.m. peak hour and Saturday mid-day peak hour. <br />For the sit-down restaurant uses, we have estimated that 60°Io of the net trips will be <br />new trips, and 40% will be pass-by trips during the weekday p.m. peak hour. For the <br />Saturday mid-day peak hour, we expect the ratio will be 70% new trips and 30% <br />pass-by trips for the sit-down restaurant use <br />
