Supporting Information: It was observed on site that the newly installed pedestrian signs for the North leg of the Highland and Walmart intersection conflicted with the existing crosswalk striping. The plans did not show any notes for any crosswalk striping removal. "Do Not Cross" signs for both NW and NE corners were installed but the existing crosswalk needs to be removed to prevent pedestrians from continuing to walk across the street. Removing the existing striping removes the limit line for traffic to identify the stop limit into the intersection. It was directed by the City to remove the existing cross walk by using the grinding method to address the conflict and install a thermoplastic stop bar. Upon removal of this crosswalk, there will be need to install stop bars throughout this intersection to control stoppage limits. Per STC's new striping plan, both the North and East leg of this intersection will have striping installed. Time Adjustment: It is recommended that one (1) working day be added to the contract time. Cost Adjustment: The total cost for removing the existing striping is $4,805.00 Project Manager ttizi Date J HIGHLAND AVENUE TRAFFIC SIGNAL MODIFICATIONS (H51P) CHANGE ORDER NO. 15 CIP NO. 18-03 November 19, 2019 Contractor: HMS Construction, Inc. 2885 Scott St. Vista, CA 92081 This Change Order modifies the Contractor's and the City's obligations and rights under the abovementioned contract.
