The otherwise applicable limits for size and height of freestanding freeway-oriented pole signs may be authorized by a special permit approved by the planning commission upon finding that such exceptions are needed to achieve visibility which is consistent with other freeway-oriented business in the vicinity and that such exceptions are consistent with other goals and policies of the city; such findings must be made without consideration of the message content of any such sign, other than the distinction between onsite and offsite commercial messages.
Full Breakdown
LMMC § 15.10.040(d)(1) governs freestanding pole signs for commercial and industrial uses in the C, CN, CD, CM, M and RB zones. The baseline height limit is twenty feet, but subsection (c)(i) creates a specific bonus for a freeway-oriented establishment located within five hundred feet of a designated freeway: the overall sign height may be increased to reach a maximum of twenty feet above the elevation of the freeway centerline, or fifty feet above the centerline of the nearest street, whichever of those two figures is less, and in no case may the sign exceed fifty feet above its own base.
Subsection (d) layers a further exception on top of that bonus: the planning commission may authorize a special permit relaxing the otherwise-applicable size and height limits for a freeway-oriented pole sign, but only on findings that the extra height or size is needed to match the visibility of other freeway-oriented businesses nearby and is consistent with the city's other goals and policies, and those findings must be made without regard to the sign's message content, apart from distinguishing onsite from offsite commercial messages. The same subsection caps ordinary pole sign area at one square foot per linear foot of street frontage (not exceeding one hundred square feet, with a twelve-square-foot bonus for motels and hotels) and limits a site to one freestanding pole sign per street frontage, two per site.
Violations & Fines
The community development director enforces sign height and size standards under LMMC § 15.10.030, and a nonconforming pole sign that exceeds these limits, or a special-permit request denied by the planning commission, is a sign-related decision appealable to the planning commission and then the city council within ten calendar days of notice. A sign built over height without the special permit is subject to nonconforming-sign abatement under § 15.10.039.
