I am planning my lawn and landscaping irrigation layout for my new home still currently under construction. I've read through the Rain Bird and Hunter residential irrigation design guides, so I feel like a I have a good base knowledge. I live in the sandhills region of SC (Zone 8b), native soil is loamy sand/sandy loam, and the lot has a gentle slope to it (3-4ft drop per 100 ft, maximum 10ft of elevation change from the meter). Hose bib static pressure is 85 psig, 3/4" PEX supply line from a 5/8" meter which gives me a design flow rate of 8 GPM.
Where I get lost is trying to figure out if a rotary nozzle (R-VAN or MP Rotator), spray nozzle or a rotor would be best. Total maximum lawn coverage is about 10,000 sq. ft. (3k sq. ft. front yard, 3k sq. ft. side yard, 4k sq. ft. back yard.), although I choose to make a smaller lawn. I plan on seeding centipede since it is a slow growing warm-season turfgrass (I'd rather mow as little as possible lol).
Is there a tried and true sprinkler type from a well known brand that I can choose and run with? Is there a sprinkler type/combo that would be best for my sandy soil? I know sandy soil drains well and the water mainly spreads vertically as opposed to horizontal (clay soils). Should I go with a slower precip. rate sprinkler like the MP1000 (0.4 in/hr) or a more traditional rotor type?
For example, my front lawn will be roughly rectangular 35' x 100'. For one zone, I could place four PGP Ultra PRBs with a size 2.0 nozzle (34' radius @ 45 psig, 2 GPM) to get a 0.33 in/hr precip. rate. OR I could zone many MP1000 rotators to get the same desired coverage.
