Irrigation Notes/Criteria to be added:
1. Sprinkler spacing shall be designed to achieve the highest possible distribution uniformity using the manufacturer’s recommendations. Spacing must achieve head-to-head coverage. All
sprinkler heads installed in the turf grass areas shall have a distribution uniformity of 0.65 or higher using the protocol defined in ASABE/ICC 802-2014 standard.
2. The irrigation system must be designed and installed to meet, at a minimum, any water windows or restrictions for operation such as day of the week and hours of the day.
3. Sprinklers within zone shall have matched precipitation rates, unless otherwise directed by the manufacturers recommendations.
4. Application rate on slopes greater than 25% shall not exceed 0.75 inches per hour
5. Any work performed under protected trees requires hand grubbing no deeper than 4
inches (4"). Any additional soil above existing grade limited to a maximum 3 inches 3").
