Title
Discuss and consider action to approve a professional services supplemental agreement with the Thornhill Group, Inc. to amend the original agreement's timeline, scope of services and cost.
Summary
The proposed services include evaluating well and aquifer data for the local Edwards aquifer in order to conduct evaluations regarding optimizing current ground-water supplies and to locate favorable well sites near the proposed Data Center site near Stone Hill Town Center to obtain additional groundwater supplies. A key component of this project will be evaluating and assessing the City's existing wells and their current conditions, and conducting drilling and testing programs to assess the potential for developing additional groundwater supplies from one or more new wells drilled in the Edwards aquifer.
Additionally, the project will include a detailed inspection of the City's existing Well No. 6 to assess the potential for modifying or refurbishing the well to enhance production capacity.
Status
As the City continues to determine viable options for planning and providing water to our customers, staff has determined the need to examine all possible opportunities to optimize groundwater supplies. This evaluation will assist with determining possible alternatives. The original agreement was approved by the City Council on August 13, 2013. A technical memorandum related to preliminary findings for Task 1 was reported to the City on September 23, 2013.
Prior City Council Action
The City Council approved a professional services agreement with Thornhill Group, Inc. on August 13, 2013 in an amount not to exceed $132,700.
Deadline for City Council Action
There is no deadline for action.
Fiscal Impact
This project will be funded from Utility Fund Balance. This amendment reduces the original budget from $132,700 to $73,500.
