I am not great at IDing all types of native ferns, (I had the Fern Finder booklet, but can't find it, Grrr) but some of them just scream their names. This is an Interrrupted Fern. You can see the brown fertile leaflets that interrupt the green sterile ones. The fronds were 2-3 feet high. This is a large in your-face-fern that grows along roadsides.
