TRAFFIC IMP ACT REPORT ADDENDUM The purpose of this addendum is to update the traffic study completed for the proposed Centre Pointe Business Park development in the Spring of2001, In particular, this addendum documents the impacts associated with modifying the single tenant office space use from 6,600 square feet to 21,500 square feet. To assess the impact ofthe additional office space, this analysis estimated the additional traffic anticipated for the expanded use, and reanalyzed the traffic operations at the study area intersections through the use of Synchro and HCS. The analyses of the traffic impacts due to the increased office space indicate no change in operations. The following discussion summarizes the findings. Trip Generation In order to assess the off site traffic impacts of the proposed development it is necessary to estimate the anticipated traffic conditions one year after its completion, thereby creating a baseline condition, Subsequently, the estimate traffic generated by the development is added to the baseline and comparison of the no-build and build conditions is conducted. In this case the baseline conditions remain as stated in the traffic impact report. The trip generation for the Centre Pointe Business Park was first estimated in 1997 for th~ original approved land use, using Trip Generation published by ITE. Table 1 presents the original estimate and is provided for comparison purposes. It is noted that the trip generation estimate has been reduced by ten percent to account for the shared trip potential associated with multi-use sites.
