Title
Consider a resolution adopting the City of Round Rock Drought Contingency Plan.

In addition to a Drought Contingency and Water Use Management Ordinance that outlines water restrictions that all water customers are required to follow, the City has developed a Drought Contingency Plan (DCP) that is required to be updated and submitted to the Texas Commission on Environmental Quality every five years. The DCP provides detail for staff as to not only when water restrictions are enacted, but also provides details as to when stages can be terminated.

Irrigation will not be permitted between the hours of 10am and 7pm year-round. Water days will be on the same two-day schedule as Stage 1 restrictions allow.
· Stage 1- 3 triggers have been adjusted based on combined storage volumes of Lake Georgetown and Stillhouse Hollow Lake as determined by the Brazos River Authority and Lake Buchanan and Lake Travis as determined by the Lower Colorado River Authority.
· Watering time will be limited to midnight to 10am for Stage 1 twice-per-week watering schedule and Stage 2 once-per-week watering schedule.
· Stage 3 trigger when Lake Georgetown water surface elevation reaches 765 mean sea level for three consecutive days.
The City has also determined that i...
