Councilmember Stuart asked: what steps are needed to plan for the anticipated water storage deficit
in Overlake, especially in light of anticipated growth in the area. CM Stuart expressed the importance of
addressing potential storage shortfalls ahead of growth.
Staff Comment: Given the ability to move water supply within the system as needed, the needs identified in Overlake can be met by adding storage in multiple locations in Rose Hill and Overlake. The well service area (including the Education Hill Tanks) can be fed by the higher Rose Hill/Overlake pressure zones but the higher Rose Hill/Overlake pressure zones cannot be fed by the well service area.
Additional storage in Rose Hill will directly benefit the Overlake area. The WSP specifically identifies adding a third storage tank on Education Hill. The total estimated cost to add the needed storage is $24 million (in 2023 $).
To provide the total volume identified in the current plan, a new reservoir site will be needed to meet the 20-year demand. 9/16
