Head selection odd shaped lawn

I am having difficulty designing my system because it has some odd shapes. For one, the main lawn has about 7 feet at the top right corner and then in comes in on a slant. I am thinking about placing a 9sst side strip nozzle and dial it down to 7 feet width. Not sure what my spacing would be to the next head which is a half circle. Then my parkway strip is 8 feet by 46 feet. I guess I could place a few center strip heads but I am concerned about water loss. Here is LA we get fined if our sprinkers water the sidewalks.

I have attached a diagram. I know I need more heads for even coverage...stilling working out the arcs.

I am replacing an old system that didn't do that bad with only two circle hads in the center of the main lawn and a few around the perimeter. Overspray goes into the shrubs.

I have at least 20 gpm

Thanks for any suggestions.
