HomeMy WebLinkAbout03-06-2018 Item 04 Authorize Advertisement of Spec 91455 - Concrete Streets and Accessibility Improvements Project Meeting Date: 3/6/2018 FROM: Daryl R. Grigsby, Director of Public Works Prepared By: Brian Nelson, Acting Supervising Civil Engineer SUBJECT: CONCRETE STREETS AND ACCESSIBILITY IMPROVEMENTS PROJECT, SPECIFICATION NO. 91455 RECOMMENDATION 1. Approve plans and specifications for the Concrete Streets and Accessibility Improvements Project, Specification Number. 91455; and 2. Authorize staff to advertise for bids and authorize the City Manager to award the construction contract if the lowest responsible bid is within the Engineer’s Estimate of $660,000. DISCUSSION Background The City’s Pavement Maintenance Plan (Pavement Plan) was adopted by the City Council on April 14, 1998. A key element of the Pavement Plan is the establishment of a rotating and methodical approach to ensuring all areas of the City receive regular preventative or corrective maintenance. The City has applied this approach to asphalt streets, which represent over 99% of City streets. This routine maintenance approach was not suitable to the City’s concrete streets, however, due to the relative longevity of concrete pavement and high costs of concrete maintenance. As a result, the City has several concrete streets which have never received maintenance. Furthermore, the City’s most recent Pavement Condition Survey indicated that, while overall Pavement Condition Index (PCI) has increase from 72 to 73; the concrete streets have declined to 35. Three concrete intersections included in this project have been identified as in need of attention. The intersections include Dana and Nipomo, Palm and Toro, and Palm and Johnson. These intersections are very uneven and present a challenge to pedestrians crossing the street, particularly those with mobility limitations. This project will allow for complete reconstruction of these intersections, including upgraded new curb ramp facilities, without impacting funding for regularly planned neighborhood paving. The new intersections will be safer and more accessible. Additionally, Dana Street, which is in poor condition, will receive an asphalt concrete overlay which will remove surface irregularities, seal cracks, and bring the roadway back to excellent condition. Completion of the Concrete Streets and Accessibility Improvements Project will enable the City to make progress towards the Council’s established goal of maintaining at least 70% of streets in good condition and have no less than 7% of the City’s streets in bad condition. This project also helps implement multimodal improvements, a Major City Goal, due to the installation of curb ramps and providing a smoother roadway surface which is more conducive to bicycle Packet Pg 29 4 transportation needs. ENVIRONMENTAL REVIEW This project is categorically exempt from environmental review pursuant to section 15301 of the CEQA Guidelines (Existing Facilities) since it is a maintenance and replacement project. A Notice of Exemption has been filed through the Community Development Department. FISCAL IMPACT There is currently a balance of $920,000 in the Street Reconstruction and Resurfacing Master Account (Specification Number 90346). A portion of those funds will be used for construction of the upcoming CDBG Marsh Street Ramps Project, leaving a balance of $840,000 for construction of this project, which is sufficient to support this request. Other sources of funding include the Water Distribution System Improvements Master Account ($3,783,838) and the Collections System Improvement Master Account ($2,512,683). These funding sources support adjustment of water and sewer facilities to the new pavement elevations. This project is 95% funded through the Local Revenue Measure.

ALTERNATIVES 1. Deny authorization to advertise. The City Council may choose not to authorize project advertisement. This is not recommended since summer is the best time to pave streets and impacts to the public and adjacent schools will be minimized.
