For reference, the currently proposed land uses within The Hub Fort Collins are expected to generate 838 daily trips with 66 of these trips occurring during the morning peak hour and 65 trips occurring during the afternoon peak hour. Based on a comparison to the previous traffic study, the proposed changes in land uses are anticipated to generate within the volume limits for daily and afternoon peak hour trips of what was previously studied. The current proposal is expected to account for a decrease of 60 daily trips and a decrease of 58 trips during the afternoon peak hour. The trips generated during the morning peak for the proposed uses are expected to exceed what was studied in the original traffic study; however, the high -volume controlling hour occurs in the afternoon which typically generates capacity related improvements on the roadway network. Additionally, an occupant for the sit-down restaurant is unknown at this time and trips under the current proposal would be less than trips in the original study during the morning peak hour if the restaurant does not serve breakfast. Based on these results of the trip generation comparison, the change in land uses within The Hub Fort Collins development should not change the results of the original traffic study, as site generated trips during the controlling afternoon peak hour are anticipated to be less than in the original study. Therefore, the proposed Hub Fort Collins project is believed to be in traffic compliance with the original "The Hub — 1415 Elizabeth Street Traffic Impact Study', prepared by Kimley-Horn and Associates on December 14, 2017. It is believed that all potential traffic impacts with the proposed project have been previously addressed within the original traffic impact study. Based on this, we believe that no further traffic analysis is needed or will be required based on this proposal.

The proposed site contains changes in land use as evaluated in the original traffic study. The original traffic study, The Hub — 1415 Elizabeth Street Traffic Impact Study, was completed by Kimley-Hom and Associates on December 14, 2017. The trip generation of the proposed land use changes within the current site were compared to the trip generation of the same parcels from the original traffic study. The original traffic impact study assumed the development of student residential apartments containing 381 beds as well as 6,202 square feet of supermarket and 6,202 square feet of shopping center land use. The current proposal consists of student residential apartments containing 381 beds, 5,900 square feet of high -turnover sit-down restaurant, and 2,000 square feet of shopping center land use. The 381 apartment beds were not utilized in the trip generation comparison due to currently being the same quantity as in the original traffic study. Site -generated traffic estimates are determined through a process known as trip generation. Rates and equations are applied to the proposed land use to estimate traffic generated by the development during a specific time interval. The acknowledged source for trip generation rates is the Trip Generation Report' published by the Institute of Transportation Engineers (ITE). ITE has established trip rates in nationwide studies of similar land uses. Trip generation is based on the ITE Trip Generation, 9th Edition (most current edition at the time of the original study) average rate equations for supermarket (ITE 850), shopping center (ITE 820), and high-tumover sit-down restaurant (ITE 932). The following table summarizes a comparison of the trip generation from the change in land uses evaluated within the original traffic impact study to the proposed changes in land uses within the current project. This trip generation comparison was evaluated to determine if the overall site is within compliance of the original study. Trip generation calculations are attached. 1 Institute of Transportation Engineers, Trip Generation: An Information Report, Ninth Edition, Washington DC, 2012.
