BACKGROUND AND PREVIOUS ACTIONS
The intersection was originally proposed and approved in the FY2019 CIP as project C4200012 and was cancelled due to proposed developer and utility projects that conflicted with the project. It was reintroduced and approved in FY2022 CIP as project 42040.
STAFF ANALYSIS
Traffic volumes at the intersection of Indian School Road & Perryville Road have increased significantly which have caused the current all-way stop to meet traffic signal volume warrants. This project will install a traffic signal and also provide additional pavement for a northbound left turn lane on Perryville Road.
Perryville Road south of the intersection and Indian School Road west of the intersection are located in Maricopa County. Perryville Road north of the intersection and Indian School Road east of the intersection are located in Goodyear. The Intergovernmental Agreement, requires Maricopa County and Goodyear to share equally in the costs of the improvements, which is consistent with each jurisdiction controlling 50% of the intersection.
