Transportation Impact Study for Hidden Canyon Residences & Preserve <br />March 2023 Page | 9 <br />1.0 INTRODUCTION <br />This report summarizes the results of the Transportation Impact Study (TIS) for the proposed project, a <br />residential development with proposed dedicated open space. The project site is located along Dublin <br />Canyon Road on the western unincorporated portion of the City of Pleasanton. <br />1.1 STUDY PURPOSE <br />The purpose of the TIS is to evaluate the impacts on the transportation infrastructure due to the addition <br />of the traffic from the proposed residential project. The report also includes evaluations and <br />recommendations concerning project site access for motor vehicles, bicycles, and pedestrians. <br />1.2 STUDY AREA <br />Dublin Canyon Road at the north of the project site would provide direct access to the proposed project <br />and connect Schaeffer Ranch Road, Foothill Road, and Laurel Creek Drive. I-580 lies to the immediate <br />north of Dublin Canyon Road and is accessible via Foothill Road. The proposed Street B would intersect <br />Dublin Canyon Road about 300 feet east of Canyon Creek Circle and provide access for all travel modes to <br />the residential portion of the project. Street B is intended for primary motor vehicle traffic whereas Street <br />A would connect with both Street B and an emergency vehicle access (EVA) road that would provide <br />secondary EVA access to/from Dublin Canyon Road. The project site is in close proximity to some existing <br />residential developments, and a religious facility. <br />1.3 STUDY INTERSECTIONS <br />TJKM evaluated traffic conditions at 10 study intersections during the a.m. and p.m. peak hours for a <br />typical weekday. The peak periods observed were between 7:00-10:00 a.m. and 4:00-7:00 p.m. The study <br />intersections and associated traffic controls are as follows: <br />1. Dublin Canyon Road & Schaefer Ranch Road (Side-street stop sign controlled) 2. Dublin Canyon Road & Proposed Street B (Side-street stop sign controlled) 3. Dublin Canyon Road & Canyon Meadows Drive (Side-street stop sign controlled)* 4. Dublin Canyon Road-Canyon Way & Foothill Road (Signalized)** 5. Foothill Road & I-580 Eastbound Off-ramp (Signalized)** <br />6. Foothill Road & I-580 Westbound Off-ramp (Signalized)** 7. Foothill Road & Stoneridge Drive (Signalized) 8. Stoneridge Drive & Stoneridge Mall Road (Signalized) 9. Stoneridge Drive & I-680 Southbound Off-ramp (Signalized)** 10. Stoneridge Drive & I-680 Northbound Off-ramp (Signalized)** <br />*In coordination with the City, the developer is proposing to install a traffic signal at the intersection of Dublin Canyon Road and Canyon Meadows Drive as part of the project. This is reflected in all “Plus Project” scenarios. <br />**Intersections 4, 5, 6, 9 and 10 are designated as “Gateway” intersections by the Pleasanton General Plan. <br />This applies to the intersections of Foothill Road with Dublin Canyon Road and I-580 on and off ramps; and <br />the intersections of Stoneridge Drive with I-680 on and off and ramps.
