Gilbert Director of Public Worksv DATE: December 10, 1999 (Council Meeting 1 -5 -00) SUBJECT: Consider Approval of the Plans and Specifications for the New Los Angeles Avenue Bridge Widening Project and Authorization to Advertise for Receipt of Bids for the Said Work DISCUSSION A. Project Scope The proposed project provides for the widening of the New Los Angeles Avenue bridge across the Arroyo Simi, generally described as follows: I. South Side Widening Only: The primary purpose of the project is to widen the bridge structure on the south side of the street - or the downstream side of the bridge. When completed the center line of New Los Angeles Avenue will be shifted southerly. 2. Bridge Width (outside dimension): The current width of the bridge is 821. The new bridge will be 117' wide. 3. Curb -to -Curb Width at Bridge: Presently there are no curbs. When the project is completed the curb -to -curb dimension will be 1021. 4. Eastbound Bridge Approach: The plans include an eastbound bridge approach approximately 120' long. This will result in a minimum curb -to -curb width of 102' between Spring Road and the bridge (existing improvements may exceed 102' curb - to -curb due to provisions for acceleration or deceleration lanes) .

Eastbound Bridge Departure: Project improvements will be compatible with the street widening on the south side of the street, which was recently constructed by the developer of the Carlsberg Specific Plan area. &. North Side Improvements: Project improvements include the addition of a sidewalk on the north side of the bridge. This new sidewalk will be extended westerly to connect to an existing sidewalk west of the bridge, and will be extended easterly to Science Drive. 7. Sidewalks: When the project is completed there will be a sidewalk on the north side of the street west of Science Drive and a sidewalk on the south side of the street all the way to and under the freeway. 8. Emergency Lane (Bicycles): When the project is completed there will be an eight feet (81) wide (minimum) emergency lane on each side of the street. The existing NO STOPPING ANYTIME prohibition on this street segment will remain in place. Although there will be no painted bike lanes, there will be painted "sidelines" and additional pavement width for emergency lanes, which will be more "user - friendly" for bicyclists. 9. Median: When the project is completed, there will be a 14' wide (minimum) painted median between the freeway and Spring Road, with left turn lanes in the painted median where required. 10- Striping: The project plans will include the re- striping of the street to provide three travel lanes in each direction between the freeway and Spring Road, plus left -turn lanes where required. There will be a right -turn lane for both eastbound and westbound traffic at Science Drive. The number three westbound lane will convert to a "Right -Turn Only" lane as it approaches Spring Road. When future planned widening occurs west of Spring Road, the westbound approach to Spring Road will have three lanes plus a right -turn lane and a left -turn lane. 11.Temporary Provisions for Pedestrians / Bicycle: The plans include the installation of two sets of concrete barriers along the south side of the street during construction, to provide a protected area for pedestrians and bicycles during construction of the project. The installation of these concrete barriers will require temporary striping "narrowing" the painted median and shifting the eastbound traffic to the north. New L A Brg _ad 000350 New Los Angeles Avenue Bridge Widening Project Authorization to Advertise December 17, 1999 Page 3 12-Construction Phasing: • Stage 1: Temporary striping will be installed shifting the existing four (4) lanes of traffic (two lanes in each direction) to the north to allow for the construction of the bridge widening on the south side of the street. • Stage 2: Certain excavation work in the travel lanes will require traffic to be restricted to one lane in each direction, to be shifted to the north side of the bridge. It is anticipated that this work and restricted traffic pattern will last approximately three (3) weeks. At the end of this work, traffic control will revert back to the Stage 1 plan. • Stage 3: Temporary striping will be installed shifting the four lanes of traffic (two lanes in each direction) to the south to allow for the construction of the sidewalk on the north side of the street. • Traffic Management: If necessary, the traffic signal controllers will be adjusted to better accommodate traffic flow for each stage of construction. • Post Construction: Again at the end of the construction project the street will be re- striped to provide three (3) lanes of traffic in each direction, plus turning lanes where required. B. Right -of -Way No additional street right -of -way is required in order to construct the project. C. Environmental Document In 1994, in the early stages of the design process, the City prepared a Categorical Exemption for this project. The Project Study Report (PSR) approved by Caltrans identified the project as Categorically Exempt. Later in the design process, the City retained a consultant to do a more thorough analysis of the potential environmental impacts of the project, with an eye toward assessing the need for upgrading of the environmental document to a Mitigated Negative Declaration. That review has been completed and the consultant has determined that a Categorical Exemption is the proper finding for compliance with CEQA. A revised Notice of Determination, documenting this latest finding that the project is Categorical Exempt, has been issued and distributed to appropriate review agencies. No comments were received within the review period. New L A Brg _ad 00035 New Los Angeles Avenue Bridge Widening Project Authorization to Advertise December 17, 1999 Page 4 D.
