6. GENERAL PLAN IMPLEMENTATION
Circulation & Mobility 1.0 Provide a safe, efficient, and comprehensive circulation system
that serves local needs, meets forecasted demands, and sustains quality of life in neighborhoods.
Policy 1.1: Plan, build, and maintain an integrated, hierarchical, and multi -modal system of
roadways, pedestrian walkways, and bicycle paths throughout the City..
Policy 1.2: Identify key intersections and streets with historical or projected traffic congestion
problems and apply creative traffic management measures to improve overall circulation.
17. DISCUSSION and BACKGROUND
Glassell St. and Palm Ave. is one of the intersections identified in the Chapman University
Specific Plan Amendment No. 5 (Specific Plan) that needs to be signalized to accommodate
projected Chapman University and cumulative growth in the City. Glassell St. is a four -lane
north -south Arterial at the Garden Grove Freeway which narrows down to a two -lane section
north of La Veta Ave. and through the Old Towne District then widens again to a 4 -lane section
at Collins Ave. Palm Ave. is an east -west 2 -lane Local Street. The intersection is currently
controlled by a four -way stop.
The existing vehicular, bike, and pedestrian traffic volumes warrant the signalization of the
intersection. Recent traffic counts show there are 10,541 vehicles, 4,107 pedestrians and 430
bicyclists entering the intersection on an average weekday between 7:00 am to 6:00 pm. These
traffic volumes result in a continuing conflict among road users at the intersection. With
projected 2016 traffic volumes, the traffic condition is expected to get worse. The traffic signal at
the intersection will define right -of -way assignment to the road users which will minimize if not
avoid conflicts.
The construction of the traffic signal at the intersection features decorative traffic signal poles
consistent with the standards of the Old Towne Master Plan of Lighting. The scope of work
includes installation of controller, cabinet, service, CCTV camera, emergency vehicle
preemption, loop detectors, LED luminaires, vehicle and pedestrian signal heads, street name
signs, ADA- compliant sidewalk access ramps, and signing and striping. Signal timing at the
intersection highlights an exclusive pedestrian scramble phase. The exclusive pedestrian phase
stops all vehicular movement and allows pedestrians access to cross in any direction at the
intersection, including diagonally.
The construction of the proposed traffic signal will not have any negative impact to the area's
on- street parking. On the contrary during design, staff was able to remove some of the existing
red curb to provide consistency with the proposed striping on Glassell Street and create 6
additional on- street parking spaces between Palm Avenue and Sycamore Avenue.
The total estimated construction costs including 10% contingencies and 5% construction
engineering is $291,180, and the available funding is $265,000. Chapman University is required
2
to contribute 62.3% of the total associated project costs as its "fair -share contribution" as
specified in the Specific Plan for the installation of the intersection traffic signal. Based on the
project cost estimate, Chapman University's fair share is estimated to be to $181,405. After bids
are received, staff will make recommendations on the contract award including additional
appropriation if needed.
This project is fully and adequately addressed in the approved certified Final Environmental
Impact Report (FEIR) No. 1717 -03 prepared for the Specific Plan. The FEIR was prepared in
accordance with the provisions of the California Environmental Quality Act (CEQA) per State
CEQA Guidelines Section 15070 et seq and in conformance with the Local CEQA Guidelines.
