<br />N Submit 30-, 60-, and 100 -portent plans to those utility companies with facilities In immediate project area for ,
<br />review and comment,
<br />• Coordinate with utility companies to implement upgrade of facilities (upon request), as needed, within project
<br />limit and Maintain contact log. I
<br />• Determine any utility upgrades or installations that will be required to service existing and proposed Improve-
<br />ments and coordinate installation of required upgrades with each affected utility company Id
<br />• Lead efforts to identify ownership of unknown utility lines
<br />Task 3 - Environmental Compliance and permits — Option A and Option S
<br />it is anticipated that the projects will qualify for Categorical Exemption Section 16301 Class 1(c) under existing
<br />highways and streets Improvements that allows for roadway Improvements for the purpose of public safety and
<br />has no significant effects on the environment, Willdan will perform Its due diligence as part of this task to verify
<br />exemptions criteria set by California Environmental Quality Act (CEQA) under Article 19 of Categorical Exemp-
<br />tions and make necessary recommendations to the City. The Clty's Planning Division will make the final environ-
<br />mental determination. To satisfy CEQA requirements for the project, Willdan will prepare a notice of exemption,
<br />for the City's use, We will assist with posting of the notice and with tiling the Notice of Exemption with the County
<br />Clerk,
<br />If Willdan believes that further detailed environmental studies and reports are needed to comply with CEQA and i
<br />or National Environmental Protection Act (NEPA), subject to confirmation by City Staff, Willdan will meet and dis-
<br />cuss with the applicable resource/regulatory agencies to confirm the necessary work effort and Identify the cost
<br />and schedule to prepare the environmental reports, applications for
<br />permits and obtain clearance through all applicable agencies as addi- J Task 3 Deliverables

<br />Task 4 — Preliminary Enginoodrng — Option A and Option R
<br />Subtask 4.01 — Site Visit and Evaluation. Visual Inspection is important for quality assurance and ensures a
<br />site facilities and constraints. Willdan will catalog existing conditions and facllltles through photographs and field
<br />r'
<br />notes to be used as a reference during design.

<br />An initial assessment will be performed to evaluate the existing condition of the water well, Based on the initial
<br />evaluations, rehabilitation options will be proposed. The entire well will have to pulled and the casing will have to
<br />be video inspected. Common causes of reduced well capacity could be sanding, rupture of casing, mineral build•
<br />LJ
<br />up, heavy encrustation, screen damage, screen clogging or mechanical failures of the pump. Depending on the
<br />assessment, rehabilitation could include brushing and bailing casing, replacing ruptured casing, adding an elon-
<br />r?
<br />gated nozzle to bull to reduce sand flow, chemical treatment, remachine the pump and or rewind. Afterthe initial
<br />LJ
<br />evaluation, Willdan will work with City's current maintenance and repair contractorto rehabilitate the well or will
<br />work with the City to bid out the project,
<br />Subtask 4,02 — Field Survey and Right -of -Way. Wllidan will perform a field survey to ensure the accuracy
<br />and constructability of the final construction plans, For this project the survey will:
<br />Establish right-of-way through record research and/or survey,
<br />r�
<br />• Option A: Ground Survey to map the existing facilities and utility Subtask 4.02 Deliverables

<br />alignment. The utility survey will include manholes, covers, and • One electronic copy of all field sur -
<br />depth of cover when required, vey data In Mlorostation VBI format
<br />n
<br />• Option B: Topographic/ground survey will be required to deter-
<br />mine existing grades and facilities. To ensure acceptable cross -slopes full street sections will be surveyed
<br />ti
<br />and analyzed at 25 -foot intervals, driveways, and at approaches. The topographic survey shall extend a minl-
<br />mum of 200 feet beyond limits of oonstruotion within the public right-of-way, where possible. Full street sec-
<br />!
<br />tions include obtaining field data at all control or critical points, such as CL, BCR, ECR, and at any grade
<br />r
<br />breaks between lips of gutters, and/or edges of pavement, and flow lines; Where applicable to the project
<br />scope, survey'of private property Improvements shall be Included.
<br />Subtask 4.03 — Geotechnical Investigation and Pavement Rehabilitation Strategies. All geotechnlcal
<br />Investigation and analysis shall be performed by a state -licensed geotechnical engineerwith expertise in pave-
<br />ment design. Willdan will conduct geotechnical Investigations to measure the existing pavement sections and
<br />r•
<br />collect representative samples of subgrade soils for laboratory testing as described below. The taslc work In-
