SCOPE OF WORK
This project consists of the preliminary design and final development of construction plans,
specifications and estimates for the re -alignment of the Fairview Park Bike Trail, from its existing paved
alignment to the "canyon" alignment located easterly of the existing trail alignment in Fairview Park,
located at 2525 Placentia Avenue, in the City of Costa Mesa, County of Orange, State of California. This
scope of work also includes construction documents for landscape planting and temporary irrigation
improvements for the Fairview Park Habitat Coastal Sage Scrub Restoration Area, as requested by the
City and as shown on the attached exhibit. Construction PS&E will be incorporated into a single bid
package with the existing planned improvements at Canyon, Placentia and Pacific per the original
contract scope of work.
In an effort to expedite and maintain the City Schedule, we have developed a scope of work outlining the
following required steps necessary to complete this project:
A. Project Analysis and Review
Organize and attend 5 additional progress meetings with City staff for design review and
coordination purposes. Includes preparation of meeting minutes within 1 week of
meeting.
B. Design Survey
Perform field survey to supplement the aerial topographic survey, and to identify existing
site specific topographic features, elevations, and improvements, including cross sections
of the proposed trail drain alignment and canyon slope area (top and toe of slopes)
elevations and trail j oin locations as required for design purposes. Includes field review
of project to identify special conditions and conflicts. Locate and identify horizontal and
vertical control used (Orange County benchmark).
2. Update the existing topographic base map for the project area at 20 scale, using computer
aided drafting (AutoCAD 2014) and the results of the supplemental field topographic
survey data.
C. Construction Documents
1. Prepare preliminary and final precise grading and paving plans for the proposed trail re-
alignment, including paving, slope and local area drainage improvements, at a scale of
1 "=20'(H) per City request in plan view only. The plans shall include plan sheets, detail
sheets with typical cross sections, construction notes, bid item numbers, and
miscellaneous details, as required. Assumes SPPWC retaining wall standard plans will
be used for any required walls, and no separate wall plans or structural design is
included herewith.
2. Prepare preliminary storm drain improvement plans and profiles, including bioswale
design, as required to mitigate drainage along the new trail alignment. Includes
hydrology and hydraulic analysis and calculations, construction notes, bid items and
miscellaneous details as required for construction.

Landscape Design (by Kobata Associates Inc.- subconsultants):
Kobata Associates, Inc. will provide the following Landscape Architectural Services for
the Fairview Park Habitat Restoration Area Coastal Sage Scrub, per the attached City of
Costa Mesa exhibit and bike trail re -alignment:
a. Construction Drawings - Prepare Irrigation Plan, Planting Plan, Irrigation and
Planting Details for subject project, including bioswale design (if required).
4. Prepare Preliminary Opinion of Probable Cost for the Project, using Microsoft Excel.
5. Submit 5 sets of prints of 70% Improvement Plans, Specifications & Cost
Estimates, to City for review and comments.
6. Revise preliminary improvement plans and plot final improvement plans, including Title
sheets, detail sheets, plan sheets.
7. Prepare Final Specifications and Final Opinions of Probable Construction Cost.
8. Submit 5 sets of prints of 100% Improvement Plans, Specifications & Cost
Estimates, to City for review and comments.
9. Revise and Submit Final Improvement Plans, Specifications and Cost Estimate for
the project, to the City, on 22"x34" Mylar and in digital format on flash drive using
AutoCAD 2014, for final approval. Specifications and estimates shall be submitted
in hard copy and on flash drive using Microsoft Word and Excel 2000.
D. Exhibits for Environmental Documentation (Hourly Estimate)
Prepare Exhibits of the proposed improvements upon City request, as required by the City's
environmental consultant to support their documentation of the proposed project.
E. Geotechnical Investigation (by SCS&T Inc: subconsultants)
Southern California Soil & Testing, Inc., (SCST) will provide geotechnical engineering services
for the alternate alignment of the planned multipurpose trail at Fairview Park in the City of Costa
Mesa, California. We understand the alternate alignment will be situated in a ravine that has
bottom levels comprised of undocumented fill. The City wishes to evaluate the undocumented
fill for suitability as subgrade support for the planned trail. SCS&T will explore subsurface
conditions by drilling 2 test borings with a hand auger to a depth of 5 feet or refusal, whichever
is less. An SCST engineer or geologist will log the test borings and assess the relative density of
the materials encountered. The results of the investigation will be summarized in a written
addendum report complete with field data.
OPTIONAL SERVICES:
1. Structural Design, Calculations & Details for Retaining Walls
2. Separate Retaining Wall Plans and Profiles
