Subject: Additional Engineering Services Contract Amendment - North State Street

Gap Road/Brush Street Project -Brush Street/ Mazzoni Street Accessibility
Improvements
Dear Mr. Seanor:
Under the direction of the City of Ukiah (City) staff, SHN Consulting Engineers & Geologists,
Inc. (SHN) is submitting an estimate to amend the existing Service Agreement for additional
services for the North State Street Intersection Traffic Signalization and Storm Drainage
Improvements - Low Gap Road/Brush Street Project.
SHN will prepare modifications to the plans to include ADA compliant sidewalk curb returns
on the two corners of Mazzoni Street at the intersection with Brush Street. Also, the proposed
driveways on the south side of Brush Street will be modified to provide an ADA path of travel
at the back of the sidewalk, together with adding curb, gutter and sidewalk on the north side of
Brush Street where none currently exists. The preparation of the modified project plans will
include the following:
TASK ONE
• Perform research and calculation of the existing right-of-way to determine the feasibility
of constructing a 25 -foot curb return on the northwest corner of Mazzoni Street.
• Perform additional topographic surveying, boundary control, and prepare an updated
topographic surface for design of the additional frontage and storm drainage
improvements.
• Prepare a new storm drain plan with details to address adding the curb return with an
ADA ramp adapting or revising the existing grated junction box and the existing storm
drain configuration that joins in the inlet at the northwest corner of the Mazzoni Street
intersection.
• Prepare a plan and profile, and details to add curb, gutter, and sidewalk along the north
side of Brush Street from the Mazzoni Street curb return westerly approximately 170 feet
to the end of the existing sidewalk within the existing right-of-way.
• Meet with the City staff to discuss the alignment options.
• Analyze plan layout options for the northeast corner curb return to upgrade the existing
ADA ramp, addressing the existing utilities in the sidewalk at the corner.
