IV. BACKGROUND
The City’s Capital Improvement Program (CIP) calls for the construction of Project No. 1628: Traffic Signal Installation at the intersection of Tajauta Avenue and Del Amo Boulevard (Exhibit No. 1).
Tajauta Avenue is a 40-foot wide local street with one travel lane in each direction, provides north-south access, and has a terminus at Del Amo Boulevard. Del Amo Boulevard is an 86-foot wide major highway with two travel lanes and a bike lane in each direction, and provides east-west access. The intersection of Tajauta Avenue and Del Amo Boulevard is stop-controlled on the southbound Tajauta Avenue approach, while uncontrolled on both the east and westbound Del Amo Boulevard approaches.
The City retained the services of P.A. Arca Engineering, Inc. (ARCA) to prepare the PS&E for this project. ARCA conducted a full signal warrant analysis, and the results of the warrant analyses indicate that existing conditions during a regular weekday satisfy Peak-Hour Warrant (Warrant 3) and Coordinated-Signal-System-Warrant (Warrant 6) for a new traffic signal at the intersection. The project consists of installation of new traffic signal improvements, it also includes installation of crosswalks and upgrade of the existing wheelchair ramps to meet the American with Disability Act (ADA) requirements. This project will improve the pedestrian and traffic safety at the intersection.
ARCA completed the PS&E and it is consistent with staff’s requirements.
