EXISTING BOULEVARD TURF TO RETAIN EXISTING IRRIGATION FROM HOA OPEN SPACE SYSTEM
Sprinklers/Overhead Irrigation1) All overhead irrigation must consist of multi-stream, multi-trajectory (MSMT) nozzles, or an approved equal, and/or rotors;2) Head(s) subject to low head drainage must be equipped with integrated check valves to avoid draining when the system completes its cycle;3) Sprinkler heads must be spaced 2 inches minimum from hardscape edges and installed flush with finishedgrade;4) Overhead irrigation must use a 6 inch minimum riser;5) Overhead irrigation spacing must be designed to achieve head-to-head coverage or per manufacturerspecifications;6) Areas less than 8 feet in width in any direction must be irrigated with drip irrigation, either subsurface orabove ground. Overhead spray irrigation is prohibited in areas less than 8 feet wide unless being used fortemporary establishment purposes only; and7) It is encouraged to connect all sprinkler bodies to the lateral line with flexible swing joints or swing pipe.
Drip Irrigation1) Drip irrigation must be used for all landscaped areas other than turfgrass, creeping or rooting groundcovers,and seeded areas;2) Drip irrigation must include a pressure regulator and filter;3) Inline drip irrigation installed on a slope must lay parallel to the elevation contours;4) Drip irrigation must be installed with the ability to easily flush the line; and5) All subsurface drip must be installed with air/vacuum relief valves per manufacturer recommendations.
Irrigation Stations/Zones1) Each zone must be designed to achieve matched precipitation rates;2) Irrigation zones must be separated based on hydrozone, which considers irrigation type (e.g. overhead ordrip) and plant water use (e.g. low, medium, or high);223) Stations that irrigate trees cannot irrigate other plant types. An individual irrigation station may irrigate morethan one tree. The established size and extent of the root zone must be considered when designing irrigationfor trees. Drip irrigation, such as emitters, root watering systems, or bubblers, must be used to irrigate trees.4) Each irrigation zone must be designed to prevent runoff, overspray, or other similar conditions.
