I could be reading it wrong, but it seems that the city of San Diego might exclude artificial turf in their rebate program, and that other programs only pay if you comply with the city’s guidelines.
Note that on that webpage, it says artificial turf won’t get you a rebate in their program, but it points to two other rebate programs, and says that rebates “may” be available through those programs. Of those two links, one link refers you back to the other link, and that link says that applicants must “follow any additional requirements for their city.”
If anybody reads that different or knows what the story is, I’d be very interested to hear.
