four American elm trees removed from Civic Park that died due to Dutch elm disease (DED). The Commission approved the plan and recommended four red oak trees to replace the four removed trees, along with the addition of two Frontier elm trees, which are resistant to DED. When the trees were removed, the heavy construction equipment needed caused significant damage to the park irrigation system and the park turf. A renovation of the outdated irrigation system was determined to be more appropriate than repairing the old existing system. Since the Transportation Corridor Parking Lot project is adjacent to the park and includes irrigation and planting, the City Manager requested the park renovation be accomplished as part of the project. DISCUSSION During the construction of the Transportation Corridor Parking Lot project, several unforeseen conditions were encountered and have caused the need for contract change orders and additional professional services. The change orders are due to unforeseen conditions and include modifications to the storm drain system and retaining walls, changes with PG&E service connection points, modifications to the irrigation, and changes with the drainage and parking lot to accommodate adjacent properties. The pay quantities for the aggregate base and the architectural wall treatment also required change orders to increase the estimated bid quantities to the actual quantities. Addressing these needed changes also disrupted the workflow, resulting in delays to the schedule. The project's schedule has also been delayed due to supply issues for several needed materials, including brick pavers, brick veneers, light standards, handrail coatings, and power equipment. Further challenging the project schedule was coordinating with PG&E to energize the equipment installed for the parking lot's lighting and electric vehicle charging stations. The Transportation Corridor Parking Lot project has required additional design services due to the discovery of unforeseen conditions. The design engineer was also requested to prepare plans for the Civic Park Landscape Renovation Plan's irrigation system and plantings, so they tie well with the irrigation and plantings constructed under the parking lot project. The executed change orders to date, as well as the change orders still under negotiation and the additional needed consultant services, have depleted the project contingency authorized by City Council in April 2021. To complete the Transportation Corridor Parking Lot project, it is estimated that an additional $210,000 will be necessary. This includes the estimated $110,000 for the Civic Park renovations and $100,000 to fund any additional change orders necessary as the project moves to the next phase: constructing the east side of the parking lot. More detail regarding change orders to date, as well those change orders still under negotiation and the additional needed consultant services, is provided below. Page 3 of 6
