To: Andrew Winje, P.E., City Engineer, City of Redondo Beach From: Ignacio Sanchez, P.E., Senior Transportation Engineer, AGA Engineers, Inc.
Subject: Artesia Boulevard Intersections Safety Improvements – Conceptual Design Plans Via the City’s Capital Improvement Program, the City of Redondo Beach has funded a project to improve safety at various intersections along Artesia Boulevard by improving the line of sight conditions for drivers making the eastbound and westbound left-turn movements. The improved line of sight is accomplished by modifying the alignment of eastbound and westbound left-turning lanes at five signalized intersections along Artesia Boulevard. The five intersections are as follows. - Artesia Boulevard at Aviation Way
- Artesia Boulevard at Green Lane
- Artesia Boulevard at Rindge Lane
- Artesia Boulevard at Mackay Lane
- Artesia Boulevard at Felton Lane
The City of Redondo Beach requested AGA Engineers, Inc. to prepare conceptual plans and develop an estimate of probable construction cost for proposed improvements. The proposed improvements include reduced width of raised medians for eastbound and westbound approaches, asphalt repairs, realignment of left-turn and through lanes, addition of buffers next to left turn pockets, lowering or abandonment of existing pull boxes on medians, and other appurtenant work, including minor signing and striping and traffic signal improvements.
In addition to the five study intersections, two intersections (traffic signals) along Artesia Boulevard: at Slauson Lane and at Vail Avenue, are also included in this assessment, but will only include minor traffic signal equipment improvements as no median work is proposed at these two intersections. The figure on next page shows the project location map.
Mr. Andrew Winje, P.E
July 11, 2022
All project intersections along Arteria Boulevard are currently signalized. Artesia Boulevard is classified as a major arterial and is also a truck route. The posted speed limit on Artesia Boulevard is 35 mph.
Artesia Boulevard is a four lane facility and there is an existing raised median on Artesia Boulevard at the project intersections. Protected/permissive left-turn traffic signal operation is utilized at all study intersections with the exception of Artesia Boulevard/Aviation Way, that intersection utilizes permissive left-turn phasing.
Field reviews were conducted to identify specific improvements at each of the project intersections.
Typical improvements at the five intersections along Artesia Boulevard include:
• Raised median modifications: reducing the width of the raised median, and realigning the leftturn pocket with a 4-foot right side buffer to improve the left-turning line of sight for the eastbound and westbound approaches.
• Implementing roadway striping modifications.
• Relocating the existing No-U-Turn signs for the eastbound and westbound traffic from the raised median to traffic signal mast-arm.
• Replacing left-turn vehicle detection loops with new loops as necessary, adjacent to the reconstructed median.
• Upgrading vehicle signal head and back plates.
• Upgrading to ADA compliant pedestrian push buttons as appropriate. • Replacing faded signs to current standards.

July 11, 2022
Exhibits showing available sight distance under existing conditions and with proposed median modifications are attached. With the proposed realignment of left-turn lanes on Artesia Boulevard, all five intersections will exceed expected sight distance.
At the two additional locations, both of which are T-intersections – Artesia Blvd/Slauson and Artesia Blvd/Vail Avenue, no median modification work is proposed at these two locations as left-turn lane is provided in only one direction and there is no impact to sight distance as there is no opposing left turn movement. Minor traffic signal upgrades are recommended at the two intersections.
The following exhibits show photographs of existing conditions along with typical proposed improvements at each intersection. Conceptual plans of proposed improvements are included for the five intersections where left-turn pockets will be realigned via median modifications. A typical curb median modification is included in the attachments. An order of magnitude cost estimate of proposed improvements is $776,000. Preliminary cost estimates of proposed improvements at each intersection are included in the attachments.
Upon receipt of City approval of the proposed improvements identified in this memorandum, AGA team will conduct topographical survey for median modifications, and prepare detailed engineering plans for the proposed improvements.
