This development is located to the south and east of the intersection of Wheaton Drive with Oak Park Drive at 4800 Wheaton Drive in Fort Collins, Colorado. This information has been revised to address City Staff review comments dated July 7, 2025 regarding the need for additional discussion on student drop-off/pick-up queues and potential off-site improvements. The intent of this analysis is to present traffic volumes likely generated by the proposed development addition, provide a traffic volume comparison to the existing land use, and consider potential impacts to the adjacent roadway network. The following is a summary of analysis results. Site Description and Access Land for the development is currently occupied by the existing Academy of Arts & Knowledge school facility. The school occupies the first floor of an approximate 50,000 square foot, 2-story building, originally constructed as a corporate office center. The second floor is understood to be unoccupied. The site is surrounded by a mix of residential and commercial land uses. The proposed development is understood to entail the refurbishment of the second floor of the existing structure to allow the current school use to expand. This expansion is anticipated to allow for an increased student capacity of approximately 180 students, for an estimated total capacity of 423 students. It is noted that full capacity is not anticipated to be achieved for approximately four years. No other new construction is proposed. Existing access to the development is provided at the following location: one full-movement access onto Wheaton Drive (referred to as Site Access). General site and access locations are shown on Figure 1. Given that the proposed development does not proposed any new construction, only the re-use of the existing building, no site plan is currently available.

A vehicle trip is defined as a one-way vehicle movement from point of origin to point of destination . Table 1 presents average trip generation rates for the existing and proposed development areas. Use of average trip generation rates presents a conservative analysis. ITE land use code 536 (Charter Elementary School) was used for analysis because of its best fit to the existing and proposed land use.

PM PEAK HOURAM PEAK HOUR TOTAL TRIPS GENERATED As Table 2 shows, the proposed development addition has the potential to generate approximately 333 daily trips with 187 of those occurring during the morning peak hour and 29 during the afternoon peak hour. Compared to the existing land use, this represents a cumulative build-out site generation of approximately 783 daily trips with 440 of those occurring during the morning peak traffic hour and 68 during the afternoon peak traffic hour. Joy Griffin July 2025 Academy of Arts & Knowledge Page 4 25-032365 Adjustments to Trip Generation Rates A development of this type is not likely to attract trips from within area land uses nor pass -by or diverted link trips from the adjacent roadway system, therefore no trip reduction was taken in this analysis. Trip Generation Distribution and Assignment The overall directional distribution of site-generated traffic was determined based on the location of development site within the City, proposed and existing area land uses, allowed urning movements, and available roadway network. Site-generated traffic is anticipated to be distributed through the existing Site Access. Distribution along Wheaton Drive is general and assumed to be 50 percent to/from the north and 50 percent to/from the south. Traffic assignment is how the site-generated and distributed trips are expected to be loaded on the roadway network. Applying assumed trip distribution patterns to site-generated traffic provides the peak hour trip volume assignments for existing access. Table 3 below uses the total new trip generation volumes from Table 2 and denotes projected additional traffic volumes at the existing Site Access intersection due to the proposed expansion.

Dependent on existing through volumes and capacity along the Wheaton Drive corridor, these added volumes may be able to be accommodated without significantly impacting current intersection and roadway operations. Joy Griffin July 2025 Academy of Arts & Knowledge Page 5 25-032365 Student Drop-Off/Pick-Up Queue Length Analysis Pursuant to City review, additional assessment of vehicle queuing for student drop-off/pick-up was considered based on the anticipated trip generation. Pursuant to various urban/suburban sites surveyed, ITE’s Trip Generation Manual describes how Charter Elementary School land uses typically experience their greatest demand between the morning peak period of 7:15 AM to 8:15 AM and the afternoon peak period of 2:45 PM to 3:45 PM during typical weekdays. It is important to note that typical afternoon peak periods for adjacent street traffic occur from 4:00 PM to 6:00 PM, outside of the Charter Elementary School peak period. Pursuant to ITE, the proposed Charter Elementary School land use experiences 453 vehicle trips during the AM peak hour of generation (7:15 AM to 8:15 AM) based on a student capacity of 423 students. Of the 453 trips anticipated, 53 percent enter the site or approximately 240 vehicles. Pursuant to information on anticipated school operations as provided by the school, it is understood that all pre-kindergarten parents must park to drop off their students and therefore are not expected to occupy the drop-off queue for any significant length of time. As such, assuming an even distribution of vehicles to the site by grade, the effective number of entering vehicles that may join the queue, as opposed to parking, is estimated at approximately 180 vehicles. Student drop-off is expected to occur within a 15-minute period from 8:00 AM to 8:15 AM, and it is expected that as many as 15 percent of the total inbound trips may arrive within the queue at one time. This would result in an anticipated peak queue length of approximately 27 vehicles. Assuming a typical vehicle length of 2 0 feet, this equates to a queue of approximately 540 feet. A site circulation plan and description of drop-off and pick-up procedures, prepared by Academy of Arts & Knowledge, is included for reference in Attachment A. Pursuant to the provided site circulation plan, an examination of the existing site reveals that the site provides pick-up/drop-off queue capacity of approximately 570 feet. Based on these considerations, it is anticipated that proposed student pick-up/drop-off queues are able to be accommodated on-site. As such, no significant negative impacts are anticipated due to student pick-up/drop-off queues, and it is not expected that adjacent roadways or intersections will be negatively impacted by the proposed school expansion. Additionally, should queuing occur exceeding that estimated for the site and the available capacity, it is noted that available on-site parking as well as adjacent on-street parking along Wheaton Drive may provide a suitable alternative to vehicle queuing. Joy Griffin July 2025 Academy of Arts & Knowledge Page 6 25-032365 07/25/2025 Conclusion This analysis assessed traffic generation for the Academy of Arts & Knowledge development, provided a traffic volume comparison to the existing land use, and considered potential impacts to the adjacent roadway network. It is our professional opinion that the proposed site-generated traffic resulting from the additional expansion may be accommodated by the existing roadway network, dependent on existing available capacity along the Wheaton Drive corridor. Additionally, it is expected that proposed student drop- off/pick-up queues are able to be accommodated on site and therefore no significant impacts to the adjacent roadway network are currently identified. We trust that our findings will assist in the planning and approval of the Academy of Arts & Knowledge development. Please contact us should further assistance be needed. Sincerely, SM ROCHA, LLC Traffic & Transportation Engineering Consultants Stephen Simon, PE Fred Lantz, PE Traffic Engineer | Project Manager Traffic Engineer ATTACHMENT A Student Drop-Off/Pick-Up Procedures AAK Families, Below are the drop off and pickup plans and directions and attached maps to help explain the process for each. Morning Drop Off Families will enter our parking lot from Wheaton and turn right, drive all of the way to the south end of the parking lot and turn left towards the building. Pull up in front of the building, remain in your vehicle, a staff member will open the car door and help your child out of the car. Continue straight ahead to the stop sign, turn left and exit the parking lot. The far north side of the parking lot heading west is one way. Do not enter the parking lot using the far left lane. Pre-K families will follow the same route until they reach the stop sign, at the stop sign turn right and park. You will meet the teacher at the side door under the stairs. Drop off will be from 8:00am-8:15am! Afternoon Pick Up: Families will park and pick up their children from the classroom. To ensure the safety of all students, families must adhere to the following traffic pattern. Doors will open from 3:20pm-3:35pm. We will not be calling students out early from 3:00pm-3:20pm, this is extremely disruptive to the end of the school day. You will enter the parking lot from Wheaton Drive and immediately turn right into the parking lot. You may then choose to turn left and park in any of the available lanes. All parking lanes are one way towards AAK. Once you have entered the building and you have your child, an AAK staff member will be out front providing opportunities for groups to safely cross to get back to your car. Once in your car, you will exit the parking lot towards AAK, at the stop sign you will turn left and exit the parking lot. The north side of the parking lot heading west is one way. Pre-K families will follow this same pick up procedure! ●You must have a permit to park for ANY length of time in a handicap parking spot. Violators will be ticketed. ●Afternoon pick up is not a time to have a conference with your child’s teacher. Please email them to schedule an appointment. A few reminders:
