AKEL ENGINEERING GROUP, INC. (2)

MEMORANDUM Date: November 14, 2024 To: Susan Hsieh, Director of Finance Gerry Beaudin, City Manager Through: Siew-Chin Yeong, Public Works Director From: Ryan Smith, Assistant Director of Utilities & Environmental Services Subject: Sole Source Justification for Akel Recommendation: PWD Staff recommends entering into this Agreement with Akel to provide engineering services to evaluate impacts to the City’s water distribution system for alternative changes in groundwater supply. Background: As part of the Regional Groundwater Facilities Project – Phase I Feasibility Study with Zone 7, the City ultimately needs to decide if it is better to build new wells on its own in the Bernal subbasin or jointly with Zone 7. As part of the analysis, the City needs to understand the impacts to the City’s water distribution system from these alternative changes in groundwater supply. If the City operates its own new wells then new piping improvements will be required to tie into the City’s distribution system. If the City instead pursues a joint project with Zone 7 then the additional water will need to enter the City’s distribution system through turnouts which likely will require pipe upsizing/replacements, new turnouts, and/or turnout boosting. To evaluate these impacts and estimate costs, this Agreement with Akel has been prepared. Under a previous and separate agreement, Akel prepared the 2024 Water Distribution System Capacity Master Plan (WDSCMP) for the City of Pleasanton (City). The WDSCMP evaluated the City’s water distribution system and recommended improvements necessary to service the needs of existing users and future development. Table 8.2 of the WDSCMP provides a summary of the recommended improvements. As part of the WDSCMP, the assumption was groundwater supply would come from new City wells at Bernal Park and Del Prado Park. This assumption is no longer accurate as now the new groundwater supply would either come from new City wells at different locations (i.e. not Bernal Park) or the joint project with Zone 7. Akel’s work as part of this Agreement would evaluate the water distribution for the newly proposed alternatives for water supply. The evaluation would determine any changes to the recommended improvements in the WDSCMP by providing a Revised Table 8.2. Docusign Envelope ID: E67CB798-34D0-4A4E-BFB8-E9718C48E0D9
