Change Order No. 1 was executed administratively on June 23,2020(See additional information in table below). The reasons for the cost increase for Change Order No.2 are as follows: • Addressing creek erosion that has progressed rapidly since the project scope of work was established. Creek erosion now poses a threat to Keller Haslet Road. • Additional time and cost due to a change in the size of the retaining wall footings. The$200,000.00 in appropriations includes funding for construction,staff time,and material testing.

Funding for this project was included in the FY2020-2024 Capital Improvement Plan in the amount of$2,420,000.00. Additional funding in the amount of$200,000.00 is needed due to increased erosion in the area which increased the size of the retaining wall needed to complete this project. The action in this M&C will update the FY2021-2025 Capital Improvement Plan. This project is located in COUNCIL DISTRICT 7. FISCAL INFORMATION/CERTIFICATION: The Director of Finance certifies that funds are currently available in the UNSPEC project within the Stormwater Capital Projects Fund and upon approval of the above recommendations and adoption of the attached appropriation ordinance,funds will be available in the Stormwater Capital Projects Fund for the Keller Haslet Culvrt Pipe Rehb project to support the approval of the above recommendations and authorization of the change order. Prior to an expenditure being incurred,the Transportation&Public Works Department has the responsibility of verifying the availability of funds. Submitted for City Manager's Office by.
