Key Findings
1. Roadway and Intersection Vulnerabilities
Analysis of 17 intersections along major corridors—including Sunset Boulevard, Pacific Coast Highway, Temescal Canyon, and Chautauqua—shows that several locations operate near or at capacity under normal conditions. During reconstruction, increased construction traffic and lane demands could further reduce reliability, particularly at constrained intersections.
Key Intersections of Concern
- Sunset Blvd & Chautauqua Blvd – A major pinch point with limited turn pockets and high peak hour delays.
- Sunset Blvd & Temescal Canyon Rd – Critical for beach, canyon, and residential access; susceptible to long queue spillbacks.
- Sunset Blvd & Pacific Coast Highway (PCH) – A heavily constrained coastal intersection where even minor disruptions propagate quickly along both corridors.
- PCH & Temescal Canyon Rd – A key access point for coastal traffic, canyon neighborhoods, and emergency response.
- Chautauqua Blvd & PCH – A constrained terminus with steep grades that limit merge speeds and queue absorption.
- Sunset Blvd & Via de la Paz – Frequently near capacity under normal conditions; serves high‑turnover commercial and residential activity.
- Sunset Blvd & Palisades Dr – Important for Highlands access and already sensitive to small changes in traffic volume.
2. Impacts of Uncoordinated Construction
Modeling indicates that if numerous home rebuilds proceed simultaneously without coordinated scheduling, intersections could experience significant delays and additional travel time on major corridors. These findings highlight the need for shared scheduling tools and consistent right-of-way management during reconstruction.
3. Need for Centralized Information
Residents reported difficulty accessing consistent updates about closures, construction activity, and curb restrictions. The analysis reinforces the importance of having a unified system where the public can receive accurate, consolidated information.
