Residential System Plan Help

Hey there.

I'm doing a relatively simple install for some friends. So far, here is my current plan. I want to know what kind of components and requirements I'll need for a system like it (Rainbird). Would the anti-siphon sprinkler valves be sufficient or does it need a dedicated bpd?

The plans, bottom to top:

Large Blue Dot - Water Meter

White Dots - Valves

Purple Dots - Sprinkler Heads

Red Line (bordering the back fence) - Zone 1 (garden bed)

Light Blue Lines - Zone 2 (lawn)

Yellow Lines - Zone 3 (veggie garden - haven't decided on sprinklers vs drip)

Approx 250ft of pipe and 3 valves total:

Zone 1 ~ 120 ft

Zone 2 ~ 75 ft

Zone 3 ~ 50 ft

Number of sprinklers will be based off spray radius

Thanks so much!
