6.1. - Page 3 of 6 that the existing grade in the field is slightly different from the existing grade shown on the project plans. Staff adjusted the design and worked with the contractor to accommodate the existing grade but the elevation changes are more significant than what was anticipated by the designer. Due to the insufficient asphalt concrete thickness and the grade changes, a complete reconstruction of the intersection pavement section is now recommended by staff. The complete reconstruction of the pavement section will allow the intersection to have sufficient strength for a major corridor with a high volume of traffic and will allow the crosswalks' slope to comply with accessibility standards. The reconstruction of the pavement section will take approximately five times the amount of asphalt to complete, thus an increase in cost. Staff negotiated additional cost of the unforeseen condition with the contractor, researched the current market cost for pavement reconstruction, and determined that the estimate provided by the contractor to be reasonable. Council had approved a contract to Seton Pacific Construction for $398,805. This contract was $151,194 less than the original staff estimate and planned budget of $550,000. Even after including the cost of this unforeseen condition, the total project cost remains under the planned budget by $11,613 for a total project cost of $538,387. The balance of the funds resides in the Active Transportation Corridor Program and would need to be transferred into the TIF/Marshall Street Project to compensate for the unforeseen condition. Seton Pacific Construction expects the reconstruction of the intersection to take one week. The striping and traffic detection loops work will follow. Overall, there is approximately three weeks of work that remains. The contractor has tentatively scheduled the reconstruction work to commence in December 2019 and to complete the project before the end of the year. FISCAL IMPACT There are no fiscal impacts to the general fund or Capital Improvement Program funding. Staff recommends a transfer of $139,582 from the Active Transportation Corridor Program into the TIF/Marshall Street Project. ENVIRONMENTAL REVIEW On March 11, 2019, the City of Redwood City as the lead agency determined that the Marshall Street Intersection Improvements at Jefferson Avenue and Middlefield Road Project met the California Environmental Quality Act (CEQA) exemption criteria as set forth in Section 15301, "Existing Facilities," because the project would be a minor alteration of the existing use of the public right-of-way. Furthermore, this project is designed to be compliant with the City's Engineering Standards and currently accepted practices. As revised, the project would continue to meet the exemption criteria of CEQA Guidelines Section 15301 because a complete reconstruction of the subject intersection would not involve any expansion of use.
