Standards for Setback and Location

The city regulates billboard location by setback from property lines, rights of way, intersection sight triangles, and distance from residential zones. Specific dimensional requirements, allowable zones, and prohibited locations are set in the municipal sign regulations and zoning chapters.

For the controlling ordinance text and zone tables, consult the municipal code and planning division guidance [1].

Standards for Illumination and Brightness

Illumination rules typically limit hours of lighting, require shielding to prevent glare on roadways and residences, and may restrict dynamic or changing-message displays. Exact lumen/brightness or candela limits, and standards for electronic message centers, are established in the city sign regulations or technical permit conditions.

Permits, Variances, and Approvals

Most new billboards and substantial alterations to existing signs require a sign permit, site plan review, and may require a variance if standards cannot be met. Permit review involves plan sets showing setbacks, elevations, illumination details, and structural calculations when applicable.
