Grigsby Prepared By: Bryan Wheeler and Matt Crisp SUBJECT: MONTEREY/OSOS TRAFFIC SIGNAL INSTALLATION, SPECIFICATION NO. 91377 RECOMMENDATION 1. Approve Plans and Specifications for the “Monterey/Osos Traffic Signal Installation Project, Specification No. 91377,” and authorize staff to advertise for construction bids; and 2. Authorize the City Manager to award a contract if the total of the bid plus contingency is within the available project at time of award; and 3. Approve the transfer of $191,000 from various Public Works Transportation accounts to the Monterey/Osos Traffic Signal Installation Project account. DISCUSSION Background The annual Traffic Safety Report (“Report”) identified the intersection of Monterey and Osos as a high collision rate intersection with correctable measures available. Red light violations in all directions was the pattern of collision identified at the intersection and the Report recommended signal mast arms to enhance visibility. The initial CIP funding for the project, as requested in the 2015-2017 Financial Plan, did not anticipate significant street work necessary for the project. During the design phase of this project, all four corners of the intersection were identified for replacement particularly to address tree root intrusion on one corner. Utility conflicts and limited space at the corners of the intersection require the antiquated signal and streetlight pole foundations to be removed and new signal pole foundations to be installed in the same locations. Each corner must then be reconstructed. This practice is not commonly used because space is usually utilized adjacent to existing foundations that does not require significant disruption of the corner. State and Federal standards for pole placement and existing underground conflicts limit the poles to their existing locations. The existing signal poles and foundations cannot be utilized, as they are well older than current standards, and cannot be upgraded in their current configuration. This increase in estimated project cost reflects increases in labor and materials for the project. The project also includes ADA improvements on the southeast corner of the intersection. A Ficus tree has created significant vertical displacement of the sidewalk. This disruption is identified as problematic by the Engineering Department and requires temporary fixes to reduce trip hazards. The Tree Committee approved the removal of the 36” box size Ficus tree located near the intersection on January 26, 2016. The public notice requirement was followed and there Packet Pg 143 11 was no appeal of the committee’s decision. The removal was conditional upon the reinstallation of a 36” box size Ficus tree near the same location which is being proposed with this project. CONCURRENCES The Monterey and Osos Traffic Signal upgrades have been identified as a mitigation measure to address the collision rates at the intersection in the Traffic Safety Reports completed in 2013, 2014, and 2015. The project is also identified in the 2015-17 Financial Plan. ENVIRONMENTAL REVIEW The project is Categorically Exempt from environmental review pursuant to CEQA Guidelines Section 15304(i) (Class 2 – Replacement or reconstruction; replacement or reconstruction of existing structures and facilities where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced). Upon approval of this item, and before bid solicitation, a Notice of Exemption will be filed through the Community Development Department. Packet Pg 144 11 FISCAL IMPACT The Monterey and Osos Traffic Signal Installation project is identified in the 2015-17 Financial Plan, Capital Improvement Plan, on Page F-29. This project is a Local Revenue Measure funded project. The original budget request was in the amount of $225,000. There is currently a balance of $217,600 remaining in the construction phase available for this project. Staff recommends the transfer of funds from various completed project and transportation accounts in the amount of $191,000, the estimated project cost of $375,000. The project’s estimated construction costs are shown below: Monterey/Osos Traffic Signal Installation, Specification No. 91377 Construction Costs $375,000 Construction Contingencies $33,000 Total for Construction $408,000 Available Funding $217,600 Funding difference -$191,000 The increase in construction costs are due to constraints discovered during the design of the project. A communications vault and fiber optic line was discovered in the area during survey of the intersection. Additionally, adjacent buildings on two corners have basements located underneath the city sidewalk. These obstructions prevent the new signal poles to be in others areas except for the existing streetlight pole locations. The process to remove the existing streetlight pole foundation and install a new signal pole and foundation is longer than a normal signal installation, resulting in increased contractor time and cost. Additionally, as part of the project, several ADA upgrades are being performed to bring the sidewalks within acceptable accessibility conditions. The southeast corner of the project must be completely reconstructed with this signal installation, due to extensive tree root damage in the sidewalk area. Staff recommends the transfer of funds to the project’s construction account. A Budget Amendment Request will transfer $191,143 from various Public Works – Transportation (50500) accounts to the Monterey/Osos Traffic Signal In stallation project account. The project accounts that funds are being transferred from are completed projects or master accounts for which the projects identified have been completed. These transfers provide sufficient funding to support project construction and of an 8% construction contingency. A fiscal impact summary of funding sources is provided below. Several of these accounts are Local Revenue Measure accounts, and are also indicated below. Fiscal Impact Summary Fund Account Phase Balance (to transfer) Account 101 90398 953 $7,508.94 Safety Report Implementation (Measure G) 400 90398 953 $12,536.96 405 90398 953 $210.00 Packet Pg 145 11 400 91321 953 $277.20 Downtown Lighted Crosswalks 400 91321 954 $3,500.00 401 90872 953 $48,477.00 General Traffic Signal Improvements (Measure G) 400 90849 953 $35,000.00 Sidewalk and Tree Replacement 401 91295 952 $83,633.06 Traffic Safety and Operations (Measure G) Costs By Type ALTERNATIVES 1. Deny Authorization to Advertise and direct staff to redesign the project within the available existing budget. This is not recommended as the ADA curb ramp upgrades must also occur at the location. 2. Deny authorization to advertise. The City Council may choose not to authorize project advertisement. This is not recommended since the project has been identified as a necessary project in the Traffic Safety Report.
