Title
Consider and take action on a resolution approving the Second Supplement to Fourth Amended and Restated Water Supply Contract between Gulf Coast Water Authority (GCWA) and City of League City, Texas (Director of Public Works)

COH anticipates initiating design activities in FY2026, with construction completion and new capacity online by 2032.
