Subject: Additional Transportation Analysis of Stanford Senior Living - Trip Generation
Comparison
The following memorandum provides an evaluation of the trip generation of the proposed
Stanford Senior Living in Fort Collins. A traffic impact study was prepared for the project and
documented in the December 16, 2020, report. This study was conducted with the proposed 137
continuing care units. The updated project will allow for 158 units. The table shown below
compares the original 137 units with the 158. It should be noted that the original trip generation
was estimated using data from the Institute of Transportation Engineers (ITE) Trip Generation
Manual, 10th Edition. The manual has been updated and the most recent version is the 11th
Edition.
As indicated in the table, the difference in the trip generation is negligible. Due to the updated trip
generation rates, the PM peak hour inbound traffic decreases slightly. Section 4.2.3 of the
Larimer County Urban Area Street Standards, August 1, 2021, indicates that a change in the
project traffic estimates of less than 20 percent, 20 peak hour trips, and/or 200 daily trips do not
require an update to the traffic study. The increases do not meet these thresholds.
Steve, let me know if you have any questions or comments.
Respectfully,
President, Rollins Consult LLC
