Kennydale Lakeline Sewer System Evaluation Condition Assessment Amendment a) AB - 2124 Utility Systems Division recommends approval of Amendment No. 1 to CAG-17- 104 with Carollo Engineers, Inc. for $526,510 for the implementation of Phase 2B for the Kennydale Lakeline Sewer System Evaluation. 2. Emerging Issues in Utilities AB - 2124 City Council Regular Meeting - 23 Apr 2018 SUBJECT/TITLE: Amendment No. 1 to CAG-17-104 with Carollo Engineers, Inc. for the Kennydale Lakeline Sewer System Evaluation Phase 2A Condition Assessment RECOMMENDED ACTION: Refer to Utilities Committee DEPARTMENT: Utility Systems Division STAFF CONTACT: Dave Christensen, Wastewater Utility Engineering Manager EXT.: 7212 FISCAL IMPACT SUMMARY: Funding for Amendment No. 1 to CAG-17-104 in the amount of $526,510, is available from the approved 2018 Wastewater Capital Improvement Program for the Kennydale Lakeline Sewer Evaluation Project budget (426.465512). There is sufficient funding in the budget to cover this amendment and the proposed construction project associated with this amendment. SUMMARY OF ACTION: The initial Phase 2A work determined that there is a strong likelihood the lakeline has a greater than 20-year remaining useful life. That determination allows us to proceed with the in-lake work to better lock down the long-term life of the facility. During the previous analysis it was also determined that the existing lakeline has at least two locations that are at 30% or lower capacity. As a result additional work is necessary, including the installation of two new access points in the lake and the need to have a contractor clean the entire lakeline to ensure it is back to full capacity. This amendment will allow our consultant to perform the additional evaluation work identified as part of the last phase of work. They will also develop a package for bid to install additional access manholes in the lake and provide for a complete cleaning of the lakeline. EXHIBITS: A. Amendment No. 1 STAFF RECOMMENDATION: Execute Amendment No. 1 to CAG-17-104 with Carollo Engineers, Inc. for $526,510 for the implementation of Phase 2B for the Kennydale Lakeline Sewer System Evaluation.
