AMENDMENT NO. 5 – EXHIBIT A-3
SCOPE OF SERVICES
KOA Corporation has provided design alternatives for the Manhattan Beach Boulevard (MBB) and Pacific Avenue Intersection Improvement Project. KOA will provide additional services for concert scenarios and Synchro/SimTraffic simulation.
The Scope of Services will include tasks for up to three (3) concept scenarios and Synchro/SimTraffic simulation:
TASK 1 – Design Concept Scenarios
KOA will use the previous base files and concepts submitted to the City on November 10, 2023, and April 25, 2024, to develop the implementation of the striping and signal modifications refined from previous conceptual plans to accommodate the redesign up to three (3) conceptual plans for the intersection of Manhattan Beach Boulevard and Pacific Avenue. The designs will include transitions to join points with the existing striping between Pine Avenue and Ardmore Avenue, but zoomed-in graphics of the area near the intersection will be prepared to facilitate the City Council review.
The three potential concept scenarios include refining the previous scenarios, A & B, and the development of a third new scenario, C. They are as follows:
• Scenario A – (New scenario)
o MBB split signal phases (East-West opposed phasing),
o Left-turn pockets to be installed on the southbound (SB) and northbound (NB) approaches,
o An eastbound (EB) bike lane and westbound (WB) sharrows to be provided,
o The westbound through lanes continue to merge west of the Pacific intersection,
o The parking on MBB is maintained on the north side past the merge area and the south side,
o A crosswalk to be installed on the west leg,
o Two northwest (NW) corner ADA ramps to be installed without a NW corner bump-out,
o Two southwest (SW) corner Americans with Disabilities Act ( ADA) ramps to be installed with an adjusted design SW corner bump -out and
o The zoom-in and refined frame is to be used.
• Scenario B – (Modified Previous Scenario B)
o Left-turn pockets to be installed on the WB, SB, and NB approaches,
o An eastbound bike lane and westbound sharrows to be provided, o The westbound through lanes merge east of the Pacific intersection,

o The MBB parking is to be maintained through 10’ through lane widths being used (despite a steep grade, 4’ bike lane eastbound and sharrows westbound),
o A crosswalk to be installed on the west leg,
o Two NW corner ADA ramps to be installed without a NW corner bump-out,
o Two SW corner ADA ramps to be installed with an adjusted design SW corner bump-out, and
o A zoom-in and refined frame to be used.
• Scenario C – (Modified Previous Scenario A)
o Left-turn pockets to be installed on the WB, EB, SB, and NB approaches,
o The westbound through lanes merge east of the Pacific intersection,
o A crosswalk to be installed on the west leg,
o Two NW corner ADA ramps to be installed without a NW corner bump-out,
o Two SW corner ADA ramps to be installed with an adjusted design SW corner bump-out, and
o A zoom-in and refined frame to be used.
Assumptions:
• Compliance review of wheelchair ramps with ADA is not in the KOA scope. • Review comments from the City are limited to one (1) round from the City.
Deliverable(s):
• Electronic submittals of Draft and Final plan for up to 3 Concept Alternatives (One sheet each for up to 3 Scenarios) at 1” = 40’ scale. • Address one (1) round of comments from the City on the draft plans.
TASK 2 – Synchro - SimTraffic Analysis
KOA will prepare Synchro model runs to perform SimTraffic analysis for the following scenarios:
1. Existing Condition Scenario - The existing conditions with no alterations to traffic control.
2. Scenario A - Implementation of the striping modifications for Left Turn lanes on the NB & SB approaches lane merge improvements west of the intersection, and installation of east-west opposed signal phasing.
3. Scenario B - Implementation of the striping and signal modifications refined from previous Scenario B plans that accommodated Left Turn lanes on the EB, NB & SB approaches with lane merge east of the intersection.

2817434v1.doc City of MB Form
4. Scenario C- Implementation of the striping and signal modifications refined from previous Scenario A plans that accommodated Left Turn lanes at all approaches with lane merge east of the intersection.
SimTraffic uses progression to minimize delay within a corridor, therefore, the SimTraffic analysis will include the following four intersections:
1. Manhattan Beach Boulevard and Sepulveda Boulevard
2. Manhattan Beach Boulevard and Poinsette Avenue
3. Manhattan Beach Boulevard and Pacific Avenue
4. Manhattan Beach Boulevard and Ardmore Avenue/Valley Drive
Assumptions:
• For the analysis, KOA will use volumes from the City-wide signalized intersection counts conducted in April 2022 and will not apply a growth factor as directed by the City staff.
• For the Existing Conditions Scenario, we will utilize signal timing charts provided by the City.
• The existing conditions, lane configurations, and pocket lengths will be taken from the most recent Google photos. The lane configurations at the four intersections, as mentioned above, will be field-verified by the KOA team.
• The signal timing for Scenarios A, B, and C will be based on the optimization of the individual phases as well as the overall cycle length. • The Scenarios A, B, and C lane configurations and pocket lengths will be taken from Task 1 Design Concept Alternatives.
• SimTraffic microsimulations will be prepared for the four (4) scenarios based on the Synchro model assumptions and results.
• One (1) round of network modifications as directed by the City will be considered.
Deliverable(s):
• Visual simulations (Model)
• Technical Memo summarizing the alternative scenarios and the results.
The memo will include tables showing delays by intersection movement for each scenario, as well as queueing on Manhattan Beach Boulevard by lane for each scenario.
TASK 3 – Additional Services
KOA will provide additional professional design services for unforeseen services related to the Project as necessary. For this task, KOA will prepare a written task proposal for the City’s approval before any work is initiated. Each task proposal shall also contain an estimated cost and a not-to-exceed amount, including all labor costs and expenses.
