Full Breakdown
160(c)(2), part of the standards for permanent signs in nonresidential zoning districts, carves out an enhanced sign allowance for 'freeway adjacent establishments,' meaning businesses that provide food, lodging, and/or fuel to freeway users. S. Highway 101 and State Highways 85 and 237. A gas station or hotel along a different arterial, even a busy one, does not qualify for these larger signs. For establishments that do qualify, the section sets three location and size rules. Signs must be located along the freeway, frontage road, or freeway off-ramp frontage, oriented parallel to the freeway rather than the surface street.
160(a). 66 square feet per lineal foot of building frontage. All other copy-height and design restrictions in the sign code, including the ban on moving or wind-activated signs, still apply to these enhanced freeway signs.
Violations & Fines
A ground or wall sign that exceeds the thirty-foot height, one hundred/two hundred-square-foot ground sign caps, or the one hundred fifty-square-foot wall sign bonus in § 19.44.160(c)(2), or a freeway sign erected at a location not adjacent to U.S. 101 or State Routes 85/237, is an unpermitted sign subject to removal. As a Title 19 zoning violation it defaults to a misdemeanor under § 1.04.010 and § 1.04.020: up to a $1,000 fine, up to six months in jail, or both, with each day the illegal sign remains a separate offense.
