Summary
Every billboard erected along Folsom's Highway 50 corridor needs its design, colors and lighting approved by the planning commission before it goes up, and any later change to the sign, including a lighting change, needs a fresh planning commission sign-off. The lighting has to read as consistent with the surrounding topography, trees and open space corridor rather than stand out on its own. Folsom Municipal Code Section 17.59.040(E)(3)(g) sets the rule.
g. The design, colors and lighting of any billboard sign erected pursuant to this section shall be subject to the review and approval of the planning commission. No changes to a sign may be made without planning commission approval. The design, colors and lighting shall be designed to be consistent with the surrounding topography, trees and open space corridor along U.S. Highway 50.
Official source re-checked September 8, 2026: no newer edition of the code had been published (publisher’s edition: current through Ordinance 1369, passed April 28, 2026).
Full Breakdown
040(E)(3): the billboard must advertise a retail center without its own freeway frontage, can't exceed twenty-five feet in height or twenty feet in width, can't exceed three hundred square feet of sign area per side, needs a conditional use permit plus a building permit plus a Caltrans outdoor advertising permit, and can't sit within five hundred feet of another freestanding freeway-oriented sign. The design, color and lighting clause singles out illumination specifically because these are the only off-site billboards Folsom allows at all, and the corridor runs through open space and tree-lined frontage the city wants the sign lighting to blend into rather than compete with.
Because the planning commission must re-approve any change, a billboard owner can't swap in brighter LEDs or a different color scheme without going back through the same discretionary review that approved the original design.
Violations & Fines
Changing a billboard's lighting, colors or design without planning commission approval is an administrative violation under FMC 17.59.070, classified Level B, carrying a monetary sanction of one hundred to twenty-five hundred dollars under FMC 1.09.012(A)(2), in addition to any conditional use permit revocation for the underlying billboard.
