3. Flow rate (gallons per minute), application rate (inches per hour), and design
operating pressure (pressure per square inch) for each station;
4. Irrigation schedule;
5. Location and size of separate water meters for landscape (if applicable); and,
6. The following statement: "I have complied with the criteria of the Water
Conservation in Landscaping Ordinance and applied them accordingly for the
