Subject: Engineering Design Proposal for Ocean Avenue and Beach Street Improvement Project Dear Alpha:
KOA Corporation (KOA) is pleased to submit the enclosed proposal to provide engineering services for Ocean Avenue and Beach Street Improvement Project in the City of Laguna Beach. The engineering services include feasibility evaluation of the concept plan prepared by SWA and the preparation of construction plans, specifications, and cost estimates. The scope of work is provided below for your review, followed by a fee estimate. Let us know if you have any questions or comments regarding this letter proposal.
PROJECT UNDERSTANDING
The project corridor includes Ocean Avenue between Forest Ave and Pacific Coast Highway (PCH) and Beach Street between Ocean Avenue and Broadway Street, both located in the heart of the City’s downtown area. The purpose of the project is to improve safety for all roadway uses and conversion of Ocean Avenue into a one-way street (southbound), contingent upon the traffic evaluation to be conducted by KOA Corporation (a separate proposal was submitted for the traffic evaluation). Ocean Avenue and Beach Street serve as important local connectors for vehicles, pedestrians, and bicyclists, while also supporting adjacent commercial, recreational, and visitor-serving uses. The exhibit below highlights the proposed improvements included in our scope of work.

TASK 2 – PRELIMINARY ENGINEERING
RECORDS RESEARCH
KOA will work with the City to obtain record drawings and documents relevant to the work site. Record drawings and documents can include, but are not limited to existing improvement plans, SWA Group concept plans, topographic maps, centerline ties, corner records, as-built plans, utility plans, etc. We will send our request for record drawings and documents through the City’s Project Manager.
UTILITY RESEARCH, NOTIFICATIONS, AND MAPPING
KOA will obtain a list from the City of utility companies known to own and operate facilities in the City of Laguna Beach.
KOA will send an email with our standard utility response form, and a map of the project site to all relevant utility companies. We will request information from them including record drawings of their facilities, prior rights information, and any planned upgrades expected in the future. Utility responses will be logged and information regarding existing facilities will be shown on our plans. In some cases, the utility owner may require a request presented on City letterhead.
We will coordinate these situations, if needed, with the City’s Project Manager. KOA will provide the City’s Project Manager with a utility response list and maps/data received when all utility companies have responded. KOA will compile all asbuilts received from the utility agencies and develop a utility base map that will be referenced in the project plans.
TOPOGRAPHIC SURVEY
Our subconsultant, KDM will perform research, obtaining record maps and pertinent data from the City of Laguna Beach and Orange County. Record centerline and right-of-way (R/W) lines will be established and included in base topographic files.
Topographic field surveys will consist of R/W to R/W (back-of-walk to back-of-walk) where accessible, cross-sections at 25’ intervals with additional sections at grade breaks, and the beginning and end of curb returns at intersecting streets.
Sections will include sidewalks, top-of-curb, flowline, lip, grade breaks, crowns and striping. Detailed surveys of existing handicap ramps will also be performed to allow determination of compliance with current ADA standards. Improvements, including but not limited to, utility structures, driveway approaches, sidewalks, trees over 6”, mailboxes, walls and fences will be located within the apparent right-of-way. Base mapping will be compiled at 1" =20 scale with 1-foot interval contours produced.
1. Topographic survey will be conducted in the following areas:
a. Ocean Avenue — From Pacific Coast Highway to Forest Avenue, including handicap ramps at each end and 25-feet beyond the ECR.
b. Beach Street — From Ocean Avenue to Broadway Street, including handicap ramps at each end and 25-feet beyond the ECR.
2. Collect detailed information for existing handicap ramps to verify conformance with ADA standards.
3. Collect standard topographic data within the R/W segments, including all hardscape features and surface indications of utilities, such as pull boxes and manholes. Catch Basins — Manhole rim, local depressions and inverts of catch basins within the topographic limits will be collected. The size and type of pipes will be noted if able to be determined.
4. Collect 25-foot intervals cross sections R/W to R/W within each of the reaches of street as described above.
Additional sections will be collected as described above. 7 Ocean Avenue & Beach Street Improvement Project Page 4 City of Laguna Beach X00025881_R1

STREET IMPROVEMENT PLANS
CURB EXTENSION DETAILS
KOA will prepare curb extension detail plans to accommodate eight (8) curb extensions along Ocean Avenue. The plans will be prepared at 1”=5’ scale and will include a detailed horizontal layout showing existing/proposed roadway improvements, right-of-way, centerline, utility manholes/valves/boxes, underground utilities, construction notes, applicable construction details, elevations, and grades. Vertical profiles are excluded from our scope of work.
OCEAN AVENUE MINOR BUMP OUTS
KOA will prepare street improvement plans along Ocean Avenue for installation of ten (10) minor bump outs to create additional traffic calming and landscaping opportunities. The street improvement plans will be prepared at 1”=20’ scale and will include a detailed horizontal layout showing existing/proposed roadway improvements, right-of-way, centerline, utility manholes/valves/boxes, underground utilities, construction notes, applicable construction details, elevations, and grades. Vertical profiles are excluded from our scope of work. Note: We have assumed that the minor bump outs will be constructed up to the edge of the existing gutter and the existing curb/gutter/flow line will be protected in place.
BEACH STREET SIDEWALK WIDENING
KOA will prepare street improvement plans along Beach Street between Broadway Street and Ocean Avenue to accommodate the widening of the northside sidewalk to a 12-foot width. Our plans will be prepared at 1”=20’ scale and will include a detailed horizontal layout showing existing and proposed roadway improvements, vertical profiles, right-ofway, centerline, utility manholes/valves/boxes, underground utilities, construction notes, and applicable construction details. Roadway cross sections are excluded from our scope of work.
SIGNING AND STRIPING PLANS
KOA will prepare signing and striping plans along Ocean Avenue and Beach Street to accommodate the proposed improvements. The signing and striping plans will be prepared at a scale of 1”=20’ and will show centerlines, existing/proposed street improvements, existing/proposed pavement delineations, pavement markings and roadside signs.
TRAFFIC SIGNAL PLANS
KOA will prepare traffic signal modification plans at the intersections of Ocean Avenue / PCH and Beach Street / Broadway Street. The traffic signal plans will be prepared at 1”=20’ scale and will show existing and proposed street improvements, centerlines, right-of-way lines, utilities of record, proposed removal and installation of signal equipment, recommended signal phasing, and vehicle detection system. The drawing will include all notes, schedules, and other features required by the City to complete the traffic signal plan. Note: During the 30% design stage we will evaluate whether a traffic signal modification plan will be required to accommodate the proposed improvements.
CATCH BASIN MODIFICATION PLANS
Based on our preliminary review of the site, the proposed improvements may impact up to four (4) existing catch basins and may require relocation. All four (4) catch basins are City owned. The area is also within the 100-year FEMA Flood Plain. CWE will conduct a brief hydrologic analysis to verify whether the existing catch basins are sized to handle the runoff generated from the existing drainage areas. No hydraulic analysis is proposed. The design plans will include plan and profile sheets for the catch basin modifications. It is anticipated that the slopes of the existing connector pipes will stay the same and therefore no hydraulic impacts are anticipated. Erosion control plans will also be included with CWE’s submittal.

SPECIFICATIONS
KOA will prepare the technical specifications using the City templates, Standard Specifications for Public Works Construction (SSPWC) and Caltrans Standard Specifications.
COST ESTIMATES
KOA will prepare and submit a cost estimate with each plan submittal to the Client. KOA will apply market construction costs for each bid item to the quantities measured using a combination of available sources including Caltrans published data, recent bid prices from other local projects, and any other data provided for our use. We will update the cost estimates based on the refinement of the quantities throughout the project.
Task 4 Deliverables:
60% plans, specifications and cost estimates.
TASK 5 – 100% (FINAL) SUBMITTAL
KOA will review the City’s 100% submittal package comments and coordinate any remaining issues with the City. We will revise the plans accordingly and submit the final, signed plans, specifications, and cost estimates to the City for approval.
Task 5 Deliverables:
Final, signed plans, specifications and cost estimates.
TASK 6 – WQMP
We are anticipating the work impact area will be greater than 10,000 square feet. We understand that the City of Laguna Beach will need a Preliminary WQMP (P-WQMP) and a Final WQMP (F-WQMP) for the project. The City falls within the South Orange County MS4 Permit area. A P-WQMP may need to be developed at the 30% design plan level, and updated to the F-WQMP which will require submittal along with the 60% design plan level. This will develop details of meeting the MS4 permit as stated in the TGD for South Orange County. Additionally, we have budgeted for up to one (1) meeting under this task.
Task 6 Deliverables:
Preliminary and Final WQMP
OPTIONAL TASK 7 – CALTRANS ENCROACHMENT PERMIT
KOA will prepare and process the Caltrans encroachment permit for the proposed work at the intersection of Ocean Avenue and PCH. We will coordinate with the City’s project manager for the required documents and signatures needed for permit processing. We will submit the following as part of the first submittal package:
• Authorization Letter signed by the City authorizing Lochner’s project manager to submit the application package on behalf of the City.
• Standard Encroachment Permit Application (DOT TR-0100) • Project plans including required worksite traffic control plans After the Encroachment Permit package has been accepted Caltrans for review, we will submit up to three (3) additional submittals for Encroachment Permit approval. We will attend up to two (2) virtual coordination meetings with the City and/or Caltrans. We have assumed the City will be responsible for renewing and maintaining the Caltrans Encroachment Permit after approval.
