Dear Ms. Blomquist:
Subject: Grand Avenue Pedestrian Bridge Traffic Engineering Services
To enhance the safety of pedestrians and bicyclists at the intersection of Grand Avenue and
Second Street and to fully study the safety improvements related to the relocated driveway on the
southeast corner of the intersection Siegfried would like to present the traffic signal modification
and study scope of work below. Said scope of work if approved will be integrated into the existing
project schedule and will become an integral part of the plan set, specifications, and project
estimates. In general the proposed traffic signal modifications would upgrade the existing traffic
signal with mast arms and signal heads, and will install audible countdown pedestrian signals.
The traffic signal modification design will conform to the City's standard design and California
MUTCD guidelines, and Caltrans standard plans, specifications and design requirements.
The specific deficiencies that will be resolved are:
• The existing traffic signal does not have pedestrian signals or push buttons.
• The existing traffic signal operates on fixed time which is not optimal for pedestrian, bike, and
traffic flow.
• The existing traffic signal timing is for pedestrian timing minimum for the vehicle timing.
Pedestrian timing occurs for every cycle regardless if pedestrians are present. This is not
optimal for pedestrian and bicycle and vehicle flow.
Scope of Work
Task 1: Traffic Analysis
The design team will provide traffic operations analysis for the proposed driveway impacts on 2nd
Street at Grand Avenue. Based on our initial field review of the project site and knowledge of the
area, we will carry out the following tasks:
• We will complete turning movement traffic counts for the intersection for the am peak hour
and the pm peak hour from lam to 9am and from 4pm to 6pm.
• We will coordinate with the civil design layout of the site to evaluate the best location for the
new driveway location.

The objective is to determine the best driveway location tomeet the requirements that the City
feels would improve pedestrian safety and traffic safety atGrand Avenue and 2nd Street and to
optimize the multimodal traffic flow in the intersection.
Task 2: Signal Modifications
Adetailed supplemental field survey of the northwest, southwest, and northeast corners of the
intersection to locate and accurately represent the traffic signal equipment, pull boxes, and
striping will beperformed bvthe design heom.BoSedupontnaffioa' na|aa-builtdnawingmforUhe
intersection provided by the City and the above survey the design team will prepare plans,
specifications, and estimates (PS&E) for the modification of the following signal elements:
• Traffic signal mast arms, signal heads, and traffic signal equipment needed to upgrade the
traffic signal to current Caltrans standards.
° Audible countdown pedestrian signals (The new pedestrian signals will be for the three
existing crosswalks)
The plans will provide the layout of the traffic signal equipment, including locations of the signal
controller/cabinet, poles, pedestrian countdown signals, emergency vehicle pre-emption,
intersection striping and signage design, andintenseobonmafehv|ightinQ. Designs will bein
accordance with Caltrans design standards, California Manual on Uniform Traffic Control Devices
(CA yWUTCD)guidelines, and the City of San Rafae|'adesign requirements. inaddition the design
team will include the signal upgrade costs into the overall projectcust estimate and include
additional special provisions for the signal work. The design team will meet with City staff, as
