HomeMy WebLinkAbout10-16-2018 Item 12 - Marsh St Bridge replacement Meeting Date: 10/16/2018 FROM: Daryl Grigsby, Public Works Director Prepared By: Brian Nelson, Supervising Civil Engineer SUBJECT: APPROPRIATE GRANT FUNDS FOR MARSH STREET BRIDGE REPLACEMENT PROJECT RECOMMENDATION Appropriate an additional $1,406,160 in grant funding for the Marsh Street Bridge Project , for a total grant funding to match the federal funded allocation of $6,946,943. DISCUSSION Background The Marsh Street Bridge, located near the intersection of Marsh and Santa Rosa Streets, was approved by the City Council in January 2013 for removal and replacement. This followed a determination by the California Department of Transportation (Caltrans) that the bridge, built in 1909, is structurally deficient. Upon this determination, the City contracted with Dokken Engineering to conduct a bridge assessment. This assessment concluded that a complete replacement of the existing bridge was the most prudent and cost -effective alternative given the age of the structure. On January 22, 2013, the City Council conceptually appr oved the removal and replacement of the Marsh Street Bridge and proceeded with design of a new fully-replaced bridge. Dokken Engineering began the design process, including development of the plans, specifications and construction cost estimate for the bridge. That work is nearly complete. Dokken is close to finalizing the environmental permitting process, and the City Council adopt ed the Final Environmental Impact Report (FEIR) for the Marsh Street Bridge Replacement project on May 2, 2017. On August 21, 2018, the Council authorized agreements for temporary and permanent construction easements from adjacent property owners. The temporary easements are necessary for equipment accessibility to San Luis Obispo Creek to conduct construction activities within the creek, provide a staging and equipment area for the bridge contractor, and provide vehicular and emergency access for a medical services business adjacent to the bridge. There will also be permanent easements acquired from two of the owners for construction and maintenance of a wing wall for the bridge. Packet Page 131 Item 12 The temporary and permanent easements are also necessary for obtaining clearance from Caltrans to enter the construction phase. This phase releases the Highway Bridge Program (HBP) grant funds fo r construction, allows advertising the project for construction bidding, enables award of the project to a responsive and responsible bridge contractor, and provides for construction of the bridge. The construction of the Marsh Street Bridge is anticipate d to start in Spring 2019. Agreements have been reached for the easements and transfer of funds is expected to take place in early October. Project Remaining Tasks The purpose of Caltrans HBP Grant Funding Program is to replace or rehabilitate public highway bridges over waterways, other topographical barriers, other highways, or railroads when the State and the Federal Highway Administration determine that a bridge is significantly important and qualifies under the HBP program Guidelines, as is the case with the Marsh Street Bridge. Caltrans provided grant funding to support the preliminary engineer ing and right-of-way acquisition, both of which are nearly complete. The below table outlines completed and ongoing tasks that are critical for the construction phase to begin in 2019. Ensuring that funding is appropriated will allow the work to proceed on schedule. Project Delivery Tasks Anticipated Completion Date Environmental Impact Report Certification February 2018 Regulatory Permitting Prior to Construction Design October 2018 Right of Way Certification October 2018 Construction Spring 2019 ENVIRONMENTAL REVIEW The City Council approved adoption of the Final Environmental Impact Report (FEIR) on May 2, 2017. In addition to National Environmenta l Policy Act (NEPA) approval with the FEIR, environmental permitting should be nearly complete with the Department of Fish & Wildlife, the Regional Water Quality Control Board, the Army Corps of Engineers and the State Historic Preservation Office. Packet Page 132 Item 12 FISCAL IMPACT The project was approved as part of the 2015-17 Financial Plan, page 3-156. This project is 88.53% funded by the HBP grant funding with a 11.47% City Local Revenue Measure match. The table below shows the funding allocation for work complete d, as well as upcoming funding requirements. Total Cost HBP Grant Funds (88.53%) City Match (11.47%) Encumbered Costs to Date: 1 Engineering & Environmental (1)$627,452 $555,484 $71,969 Future Costs: 2 Preliminary Engineering (2)$62,931 $55,713 $7,218 3 Property Acquisition (Purchase of Easements)$158,553 $140,367 $18,186 4 Construction $7,625,000 $6,750,413 $874,588 5 Total Future Costs:$7,846,484 $6,946,493 $899,992 6 Total for Project:$8,473,937 $7,501,976 $971,961 7 Remaining Funds for Allocation:$7,846,484 $6,946,493 $899,992 8 Total Appropriated Funds $6,538,373 $5,540,332 $998,041 9 Total Additional Funds Required $1,406,160 $1,406,160 None Marsh Street Bridge Replacement Project (Specification No. 90480) (2) Design contract amendment from Dokken Engineering due to additional design & property acquisition service costs (1) Contract with Dokken Engineering, which includes design, environmental permitting, and property acquisition Staff recommends the appropriat ion of $1,406,160 in HPB grant funding that Caltrans’ has provided to the City to the construction phase of the Marsh Street Bridge Replacement project. ALTERNATIVES Deny allocation of grant funding. The City Council could choose to not allocate grant funding for the project. Staff does not recommend this alternative. Recognizing the availability of grant funding is necessary to fully fund ongoing des ign and right of way costs, as well as budgeting for construction in 2019.
