Great news! I recieved a reply from the Port A Deputy City manager today:
Tim –
The ordinances you posted are correct. You can beach launch in the I.B. McGee County Park (from the south jetty to within 250’ of the fishing pier) and anywhere south of Beach Access Road #1 (the golf course road). We always have a turnover in the police force so many of the new officers don’t know the regs. I’d just print out a copy of ordinance so you can show them. Or just tell them “Dave Parsons” said it was okay.
Take care and have some fun,
David
