This development is located southwest of the intersection of Squadron Drive and Terrazzo Drive in Monument, Colorado. The intent of this analysis is to present traffic volumes likely generated by the proposed development, provide a traffic volume comparison to previous land use assumptions approved for the development site, 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 vacant and surrounded by open space and a mix of industrial and commercial land uses. The proposed development is understood to entail the new construction of two buildings, supporting a total of approximately 354,200 square feet of warehousing space. Proposed access to the development is provided at the following locations: one full-movement access onto Squadron Drive (referred to as Access A) and two full-movement accesses onto Terrazzo Drive (referred to as Access B and Access General site and access locations are shown on Figure 1. A conceptual site plan, as prepared by VanTrust Real Estate, LLC, is shown on Figure 2. This plan is provided for illustrative purposes only. ---PAGE BREAK--- Development Site Baptist Road Old Denver Road Squadron Drive Woodcarver Road Terrazzo Drive Interstate 25 Struthers Road May 2024 SQUADRON & TERRAZZO INDUSTRIAL Traffic Generation Analysis SM ROCHA, LLC Traffic and Transportation Consultants Page 2 Figure 1 SITE LOCATION Not to Scale ---PAGE BREAK--- Access A Access B Access C Squadron Drive Terrazzo Drive May 2024 SQUADRON & TERRAZZO INDUSTRIAL Traffic Generation Analysis SM ROCHA, LLC Traffic and Transportation Consultants Page 3 Figure 2 CONCEPTUAL SITE PLAN Not to Scale ---PAGE BREAK--- Erick Hartzell May 2024 Squadron & Terrazzo Industrial Page 4 24-042149 Vehicle Trip Generation Standard traffic generation characteristics compiled by the Institute of Transportation Engineers (ITE) in their report entitled Trip Generation Manual, 11th Edition, were applied to the previously assumed and proposed land uses in order to estimate the average daily traffic (ADT) and peak hour vehicle trips. 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 previously assumed land use, as approved within the Falcon Commerce Center Phase 2 Traffic Generation Analysis1, and for the development area proposed. Use of average trip generation rates presents a conservative analysis. ITE land use code 150 (Warehousing) was used for analysis because of its conservative rates and best fit to the previously assumed and proposed land uses.

Compared to the previously assumed land use, this represents a potential increase in site generation of approximately 93 daily trips with 9 of those occurring during the morning peak hour and 10 during the afternoon peak hour. Adjustments to Trip Generation Rates While the overall mixed-use Falcon Commerce Center development area is likely to attract trips from within area land uses, no trip reduction was taken in this analysis. This assumption provides for a conservative analysis. Trip Generation Distribution and Assignment Overall directional distribution of site-generated traffic was determined based on existing area land uses, the site location within the Town, the available roadway network, and in reference to historical traffic count data provided by the Colorado Department of Transportation’s (CDOT) Traffic Count Database System (TCDS)2. Site-generated traffic is anticipated to be distributed through each proposed access. Distribution along Baptist Road is general and assumed to be 85 percent to/from the east and 10 percent to/from the west. Distribution along Old Denver Road is assumed to be 5 percent to/from the north. 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 the proposed accesses. These volumes are then divided further upon travel through adjacent roadways serving the overall development area. Table 3 below uses the difference in trip generation volumes from Table 2 and denotes projected traffic volumes at each proposed access. 2 Transportation Data Management System, MS2, 2024. ---PAGE BREAK--- Erick Hartzell May 2024 Squadron & Terrazzo Industrial Page 6 24-042149 Table 3 – Site Generated Trip Assignment DEVELOPMENT ACCESS TURNING MOVEMENTS Inbound Volume Outbound Volume Inbound Volume Outbound Volume Access A / Squadron Drive Eastbound Through 0 - 0 - Eastbound Right 1 - 1 - Westbound Left 2 - 1 - Westbound Through - 0 - 1 Northbound Left - 0 - 1 Northbound Right - 0 - 2 Access B / Terrazzo Drive Eastbound Left - 1 - 3 Northbound Through - 1 - 1 Southbound Through 1 - 0 - Southbound Right 3 - 1 - Access C / Terrazzo Drive Eastbound Left - 1 - 1 Southbound Right 1 - 0 - - AM PEAK HOUR PM PEAK HOUR Development Impacts As Table 2 shows, there is an increase in peak hour traffic volumes anticipated for the proposed development. However, as shown in Table 3 above, these volumes are considered minor and are not likely to negatively impact operations of Squadron Drive, Terrazzo Drive, nor other adjacent roadways or intersections. ---PAGE BREAK--- Erick Hartzell May 2024 Squadron & Terrazzo Industrial Page 7 24-042149 05/21/2024 Conclusion This analysis assessed traffic generation for the Squadron & Terrazzo Industrial development, provided a traffic volume comparison to previous land use assumptions for the development site, and considered potential impacts to the adjacent roadway network. It is our professional opinion that the proposed site-generated traffic resulting from the development is expected to create no negative impact to traffic operations for the surrounding roadway network and proposed site accesses, nor at the Squadron Drive intersection with Terrazzo Drive. Analysis of site-generated traffic concludes that proposed development traffic volumes are minor. We trust that our findings will assist in the planning and approval of the Squadron & Terrazzo Industrial development. Please contact us should further assistance be needed.
