In 1994, the Plaza and Towers were installed in Civic Park to commemorate Pleasanton's 100th anniversary. Over time, the soil supporting the plaza settled, creating an uneven surface that caused water to pond. The uneven surface created accessibility issues, and the ponding water eventually impacted the in-ground up- lighting of the towers' art pieces. The Centennial Tower Plaza Renovation Project CIP No. 20770 was funded in the Fiscal Year 2019/20 Capital Improvement Program. The Centennial Towers Plaza renovation was included under the Downtown Transportation Corridor Parking Lot project to attract interested bidders, save costs, and promote timely construction. Civic Park On August 12, 2021, staff presented the proposed Civic Park landscape renovation plan to PRC for a review and a recommendation regarding tree replacement. Due to Dutch elm disease, four heritage American elm (Ulmus americana) trees were removed from Civic Park in fall 2021. The removal of the elm trees and impacts from the adjacent construction damaged the turf and irrigation of Civic Park. DISCUSSION Transportation Corridor Parking Lot The downtown transportation corridor parking lot expansion consisted of replacing and widening the existing 60-stall gravel parking lot to accommodate 139 parking stalls on an asphalt pavement surface. A new 13-foot-wide multi-use trail was constructed along the parking lot, separated by a retaining wall. The parking lot was completed to incorporate more than 2,000 new street trees and plants, Silva Cells to improve tree health and provide for water treatment and storage, 14 new light poles that provide lighting for vehicle and pedestrian traffic through the corridor, and three electric vehicle charging stations that provide charging opportunities for up to five vehicles. Centennial Towers Plaza The Centennial Towers Plaza renovation included removing and replacing the plaza flatwork, lighting, and site furnishings. The engraved centennial bricks were removed, cleaned, and put back in place with a new concrete base to prevent further settling. Civic Park The Civic Park renovation included the planting of four new large red oak trees and two medium-sized Frontier elm trees to replace the four removed elm trees, new landscaping strips, irrigation updates, and the grading and replacement of existing turf. The Civic Park renovation was completed for $110,000 rather than the estimated cost of $160,700. Bud et Several unforeseen conditions were encountered during the project's construction, requiring change orders and utilization of the project allowances. The final construction contract cost, including contract change orders, was $2,797,125.47. Page of ,5
