Recently, the City of Fort Collins has developed additional comments on the traffic impact study. The following list summarizes each comment and the detailed response including any supporting information. TRAFFIC STUDY ASSUMPTIONS The City of Fort Collins requested that the base traffic study assumptions be included with the traffic study. Included with this addendum is Figure 1, summarizing the approved traffic study assumptions. INTERNAL REDUCTION The City requested that the base assumptions for the internal trip reduction be included with the traffic study. Included with this addendum is a copy of the daily and PM peak hour internal trip reduction calculations. The attached calculations are based on the procedures in the Trip Generation Manual and reflect land uses (440 unit apartment complex) shown in the original traffic impact study submitted to the City for review. Subsequent to the first submittal of the traffic study, the land use assumptions for the proposed development changed. The number of apartments increased to 800 total units and approximately 88,000 square feet of retail space was added. The same trip reduction procedures were applied to the updated land uses and the results showed the percentage of internal trips would significantly increase. Given the intensity of the proposed retail square footage, the commercial uses have the ability to attract a large percentage of the residential trips that would be generated. The resulting external trips would be nearly identical to the trip generation estimates for the original land use assumptions. We determined it would not be appropriate to include the increased internal trip reduction with the updated traffic impact study. Therefore to provide a conservative (high) estimate of the external trips in the December 2012 traffic study, the internal trip values from the original traffic impact study were utilized and applied to the revised trip generation estimates. March 15, 2013 Mr. Bryan McFarland Page 2 SHORT TERM BACKGROUNDT RAFFIC SCENARIO The City requested additional information as to the reason a short term background traffic analysis was not completed as part of the traffic impact study. The short term background traffic scenario would analyze the conditions on the transportation network assuming Foothills Mall would not exist. Traffic currently generated by the Foothills Mall development, even the retail uses that would continue to remain on-site, would need to be removed from the system at each of the study intersections. The resulting analysis would show intersections operating at levels of service far superior to current conditions, providing the basis in determining the overall impact the proposed redevelopment would have on opening day. Using this artificial condition would not provide a reasonable comparison to determine the impact additional commercial uses would have on the transportation network. With the redevelopment, a significant portion of the existing uses will remain on-site and will continue to generate traffic. Therefore comparing the opening day traffic to the existing traffic conditions gives a better representation of the relative impact the new retail uses would have on the system. If you have any questions concerning this analysis or need additional information, please feel free to call (303-721-1440) or email (Jeremy.Hahn@fhueng.com) anytime.
