Re: Additional Services Associated with Curb Radius Improvements at SW Corner of Gobbi & State Streets -
Amendment #3
Dear Rick:
Per your request and previous phone conversations, we have enclosed a brief scope of services and associated
fee for the curb return improvements associated with the SW corner of Gobbi and State Streets. It is our
understanding that the City wishes to expand the scope of services that were performed under contract
amendment #2, to include a much larger radius than what was proposed. We have increased the radius from
approximately 12' to the current 25', which will facilitate larger trucks in the turning movements.
Our Understanding
We understand that the City would like to increase the radius of the referenced intersection at the SW corner
beyond what was originally agreed upon in order to accommodate truck turning movements, as feasible. The
increased radius will require the modification of the existing traffic signal, storm drain and catch basin relocation,
extensive concrete reconstruction, and the preparation of legal documents for right of way acquisition. The
proposed work will be coordinated with our existing project and included in the set of plans that have been
prepared for advertisement and construction this summer.
The final improvements to the SW corner will result in a dedicated right turn lane with a stacking length as
feasible within the physical constraints of the corner.
We will work with WTrans Traffic Consultants for the preparation of the signal modification plans and have
included their scope of work and associated fee below.
75% Design and Improvement Plans
We will submit revised 75% design documents that will incorporate the proposed additions above, including: the
structural section details for the widened curb return, horizontal limits proposed for the curb return, turn lane and
the pavement reconstruction improvements, and the detailed grading plan for ramp conforms, striping and
signing, and conceptual signal modification plans (electric plan, details and schedules, signal interconnection
system modifications). The plan sheet will indicate existing right-of-way lines and any pertinent easements,
topographic features, and existing utility systems. Previous project specifications that were submitted for the
water main and pavement reconstruction improvements will be amended for the additional work to allow for
subsequent advertising.
Upon approval of our preliminary layout, we will prepare the necessary R sheet and legal description to allow the
City to negotiate for the needed right of way.

An updated cost estimate will also be submitted to allow for budgeting purposes.
100% Design and Improvement Plans
A 100% submittal of the plans will incorporate all comments from the 75% review, as well as results of utility
company reviews of the plans. The civil component will include final grading details, storm drain relocations,
striping and signing and any miscellaneous details will be included. The electrical plans will include existing and
proposed conduits, pull boxes, poles, vehicle and pedestrian heads, detector loops, controller and service
cabinets, luminaires, conductor and equipment schedules, preemption equipment and pertinent notes,
including those necessary to ensure that Contractor maintain an operation signal during construction.
Construction documents will be prepared in accordance with the City of Ukiah Design and Construction
Standards. The final cost estimate will updated to incorporate current bid results.
Fee for Amendment #3 $22,995
Thank you again for the opportunity to submit a proposal for our services. Should you accept our proposed
scope of services and associated fee, Green Valley can begin work upon authorization to proceed. We look
forward to hearing from you and please do not hesitate to contact us with any questions you may have.
