Not sure if this site is good for paragliding or not.
\'Rebar\' Dan: I suggest you go have a look in person. Powerlines, mounds, fences, sign poles, gullies and the strong afternoon sea breeze probably disqualify it as a P3/H3 site.
Rules
There is a class C overhead. ONT begins about 1300 over launch: 2500msl.
