DISCUSSION Approval of this recommended action will cover the cost increases resulting from unforeseen conditions experienced during the construction of the Sunflower Avenue Rehabilitation Project. The cost increase is due to added asphalt thickness to ensure a suitable pavement structural section. The City of Costa Mesa is the lead agency for design, construction, and construction management of this project. On April 1, 2014, the City Council executed a cooperative agreement in the amount of $35,000 to participate in the Sunflower Avenue Rehabilitation Project administered by the City of Costa Mesa. During construction, the contractor encountered existing base material that is not suitable for asphalt overlay. To ensure the integrity of the new pavement, an additional 2 inches of subgrade material needs to be removed to accommodate an additional 2 inches of asphalt. This process also requires additional excavation, replacement asphalt, and pavement fabric. Since the additional work was not included in the original agreement, staff is requesting an additional $16,000 to pay for the work. ENVIRONMENTAL IMPACT There is no environmental impact associated with this action. 25E -1
