6. GENERAL PLAN IMPLEMENTATION
Infrastructure Goal 3.0 Ensure adequate maintenance of public rights -of -way to enhance
public safety and improve circulation.
Policy 3.3: Continue to design, install, and maintain signals, signage, streetlights, and traffic
control devices within rights -of -way.
7. DISCUSSION and BACKGROUND
The traffic signal modification at the Glassell Street and Walnut Avenue intersection will provide
protected left turn phasing for the north -south and split phasing on Walnut Avenue for the east -
west approaches. At the Chapman Avenue and James Street intersection, a protected left turn
phase for the east -west approaches will be added.
The two projects were approved for funding under the Federal Highway Safety Improvement
Program (HSIP). HSIP provides a maximum of 90% reimbursement for eligible project costs,
while the local agency contributes the remaining 10 %. The purpose of the program is to reduce
traffic fatalities and injuries on public roads by implementing infrastructure related highway
safety improvements. The installation of left turn and split phasing will also improve the
operational efficiency by assigning through and left turn movements through the intersection, and
enhance pedestrian safety.
KOA Corporation has completed the preparation of plans, specifications, and estimates for the
projects. The total estimated construction cost for the two projects including contingencies and
construction engineering is $575,000 while the projects available funds are $572,260. When bids
are opened and actual cost known, staff will make recommendations on the contract award
including any additional appropriation that may be required. The two projects are combined into
one bid package to take advantage of the economies of scale and ease of construction
coordination with one contractor.
The scope of work, in general, includes removal of existing and replacement with new signal
poles, mast arms, luminaries (safety lighting), signal head indications, electrical service,
illuminated street name signs, and concrete foundations; installation of signal controller cabinets,
signal controller and battery back -up systems, service pedestals; installation of emergency
vehicle preemption (EVP), new conduits and conductors; and construction of ADA compliant
sidewalk access ramps. At the intersection of Glassell Street and Walnut Avenue, the traffic
signal improvements will feature decorative traffic signal poles consistent with the standards of
the Old Towne Master Plan of Lighting.

The projects are categorically exempt from the provisions of the 2016 CEQA Guidelines under
Article 19. "Categorical Exemptions ", Section 15301 "Existing Facilities ", classifies this project
as Class 1 (b) "Existing highways and streets, sidewalks, gutters,... ". The categorical exemption
applies to the project because the installation of the protected left -turn phase and split phase are
for safety and involve negligible or no expansion of the arterials' existing use. The Notice of
Exemption has been filed with the County of Orange.
Construction is anticipated to start this fall and is expected to be completed in approximately six
months.
