Help with a Design

Ok so this is my first ever sprinkler installation design. I have made a map of my backyard and I think that I have everything ready.
I am just going to hook a hose up to my faucet (with a vacuum breaker) and have it lead to a pvc pipe which will go underground into a zone box. I tested the faucet and the psi is at 50 and the GPM is 6.8



Now I have a couple of questions for the community. I am thinking of installing these sprinklers throughout my entire lawn. ( http://www.sprinklerwarehouse.com/Hunter-Sprinkler-Spray-Body-p/pros-06-prs30.htm )
I will be using two nozzles, one for a 10' radius and another for a 15' radius.

Here are my questions...
Will the setup that I have so far work? (See picture below)
How should I split up my zones?
Should I have my zone box close to the backyard where all my sprinklers are or closer to my faucet which is by my house?
How many sprinklers should I have per zone?


Here is my floor plan so far. Red circles indicate possible sprinklers and blue circles indicate the sprinkler radius.

First off, you can't feed a zone valve manifold through a vacuum breaker connected to a hose bib. That is a code violation that puts the house water supply at risk of contamination. What you can do, on a flat property, is have a manifold of antisyphon valves attached to the hose bib. They each have a built-in vacuum breaker at the correct point in the line of plumbing, and being above ground at the hose bib location, they have the elevation to be a foot higher than the sprinkler heads.

Second, is the need for a more thorough plan. You don't want sprinklers spraying onto the patio, so trade in the 10-foot-radius nozzles for 8-foot-radius nozzles, and draw a plan with more regular placement and overlap near the patio. What covers the strip near the patio? (by the way, your image host may not allow "remote viewing" on another webpage, so I moved a copy to a host that does)

Thank you for the help. I was able to fix some the errors that I made in the picture and also I replaced the 10' sprinkler with an 8' sprinkler. The reason why I didn't put any sprinklers by the strip near the patio because the narrow 3' space really does not allow me to put any sprinklers on it. I could not find any 3' radius sprinklers and even if I did I would probably have to put a lot of them. Since the sprinklers nozzles I am buying are 0 to 360 degree adjustable I though I would take advantage of that and just buy less sprinkler heads and have them cover a larger amount of grass (10' and 15') by placing them on 90 degree and 270 degree corners. This way I only have two instances where I am either spraying a little water on my neighbors lawn or a little water is hitting the siding of the garage.

I am still just confused how many sprinklers I should have per zone. I looked at the webpage of the sprinkler and I could not find any place where it mentioned the GPM or PSI minimum required for operation. http://www.sprinklerwarehouse.com/Hunter-Sprinkler-Spray-Body-p/pros-06-prs30.htm

I think you need to take your diagram to Rainbird and have them supply you with a design.
