RE: Solarium, Fort Collins – Parking Study
This Parking Study is for the Solarium project located at 706 E. Stuart Street in Fort Collins,
CO. The Solarium project consists of the following:
• Lodging (16 rooms)
• Event Venue (150 people maximum)
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 generation rates in nationwide studies of similar land uses. For
this study, KE used the ITE 10th Edition Trip Generation Report average trip rates. The
Institute of Transportation Engineers’ (ITE) Trip Generation Manual, 10th Edition does not
provide detailed data on the event venue use associated with the project. As such, KE was able
to estimate the peak hour trip generation for this use based upon correspondence with the client
and project team. The proposed project is anticipated to generate a maximum of
approximately 281 daily trips, 20 AM total peak hour trips, and 120 PM total peak hour trips.
See Table 2: Trip Generation.
Event Venue:
Guests: 150 maximum
Passenger vehicles: 60 round-trips/day for personal vehicles (120 daily trips)
Carpool = 2.5 attendees to vehicle
Occasional corporate events/meetings are anticipated to occur during the weekday am peak
hour

The Institute of Transportation Engineers (ITE) also provides guidance on calculating vehicle
parking generation rates for land uses in the ITE Parking Generation – 4th Edition. Using the
appropriate adjustment factors and the ITE Parking Generation manual, the total land uses in
the Solarium project results in an on-site peak parking demand of 64 total parking spaces. See
Table 1.

Based upon the proposed land uses, conversations with the client and project team, and the
vehicle parking generation rates for land uses in the ITE Parking Generation – 4th Edition,
Kellar Engineering LLC has no objections to the Solarium project proceeding with a minimum
of 64 total parking spaces. Based upon the site plan, the proposed project has 11 on-site
parking spaces (10 regular and 1 ADA). Therefore, a minimum of 53 additional offsite
parking spaces will need to be provided. The location(s) for this offsite parking will need to be
approved by the City.
