Value shown is amortized over the lifetime of the proposed <br />Project (assumed to be 30 years). <br />3. Based on the Trip Generation Assessment prepared by Linscott, Law & Greenspan Engineers (dated January 2, 2024), the <br />Project would result in a net decrease of 386 gross daily trips compared to existing conditions; refer to Attachment K. <br />Nonetheless, zero additional trips are inputted for a conservative analysis. <br />Source: Refer to Appendix A of Attachment F, Greenhouse Gas Emissions Assessment, for assumptions used in this analysis <br />20 Modeling was performed for a project with three industrial buildings totaling 325,044 square feet. However, since <br />the completion of the modeling, the total building square footage has been reduced to 313,244 square feet. <br />Therefore, the Project's GHG emissions inventory is conservative. <br />July 2024 Page 53 <br />
