From the Boulder Daily Camera (Heath Urie):
The city’s drought strategy calls for reducing the overall amount of water that Boulder uses — including residential, commercial and government uses — by up to 40 percent during the most extreme water shortages. A “moderate” drought, the lowest level of an official drought declaration, calls for citywide water reductions of 8 percent. Allowing the city manager to reduce water budgets during a drought is designed to be an easy way of reducing overall water consumption citywide. Other regulations that are still in the draft stages would impose additional fines on customers who repeatedly go over their water budget during a drought.
