Introduction JR Engineering (JR) has completed a review of the traffic impacts of the proposed Residence Inn Hotel located near the northeast corner of the S. Abilene Street and E. Yale Avenue intersection in Aurora, Colorado. The purpose of this traffic impact study (TIS) is to assess the short-term and long-term effects of the proposed development project on both the local and regional transportation system. The Residence Inn Hotel project site is located within the southwest 1/4 of Section 30 of Township 4 South, Range 66 West, 6th Principal Meridian, City of Aurora, County of Arapahoe, and State of Colorado. The site is located between S. Abilene Street and S. Anaheim Street. Interstate 225 is located to the west of the site, a United States Postal Service (USPS) office to the north, and the St. Andrews Village retirement community to the south and east. The project site encompasses approximately 2.0 acres. The site is proposed to be developed into a single hotel with 102 rooms and 88 vehicular parking stalls. The preliminary site plan is included in Appendix E. The developer anticipates starting construction in 2019, and the hotel would open in 2019 or 2020. Access to the site is proposed in two locations, both located off S. Abilene Street. The northern access point will be referred to as “A1” in this study and will be restricted to a right-in/right-out (RIRO). The southern access point will be referred to as “A2” in this study and will be full movement. The access spacing between A1 and A2 is approximately 400 feet. The remainder of this report presents our findings concerning the traffic impacts of the proposed Residence Inn Hotel project. The existing, one year after completion of the development and Year 2040 will be evaluated in this study. Section 2: Existing Conditions The vicinity map is shown in Figure 1. The existing site is comprised of vacant land with minimal vegetation. A sidewalk with pedestrian lighting runs along the west side of the property. The sidewalk is attached to S. Abilene Street. The existing ground is minimally vegetated with native seeding. The soils are described as Blakeland Loamy Sand (BoD2) by the NRCS soil survey. The soils are all part of Hydrologic Soil Group A. The site slopes average from 1% to 9%. The site drains generally to the north and northeast. The surrounding area is similar to the project site and includes primarily existing buildings, paved areas and minimally-landscaped areas. A USPS office and 2-10 Home Buyers Warranty corporate office are located to the north, and the St. Andrews Village retirement community is located to the south and east.
