SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Is this too many zones? I'm considering a proposed system with 24 zones. 45 rotors, 17 turf sprays, 44 shrub sprays. I've got low pressure (68psi at faucet), and they've suggested a .75 hp pump. My lot is over .75 ac. Sort of U shaped (with the left side curving out wider) with the house in the middle. The straight part (top of U) is about 240 ft long. The radius to the bottom of the U is almost 100 feet. I've got almost 500 ft of street frontage. Shortest distance from street to house is 50-60 feet. 3 rows of rotors going around the curved part of the U.

I'm worried about how long it will take to water, but no one put in a bid with less than 21 zones. I went with this guy because of his service reputation, installation practices and the feedback I got from other customers.

I know I probably haven't provided you enough information, but from what you can tell, does it seem to be a good design? Thanks for the help.
