Full Breakdown
Section 16-6-3-1 states the SOD was established along the three-mile Freeway 61/151 corridor to protect visual aesthetics, protect and enhance vistas to and from the Mississippi River valley, and eliminate visual clutter viewable from the freeway while still allowing appropriately sized signage. Section 16-6-3-2 divides the corridor into Areas A through G by street and landmark boundaries, including Locust Street, Grandview Avenue, Dodge Street, the Julien Dubuque Bridge and Schmitt Island, with Area C eliminated because it lies entirely within the Port of Dubuque PUD.
Section 16-6-3-3(A) bans off-premises signs entirely in Areas A, B and D. Section 16-6-3-3(B) sends Areas X, Y and Z to the standard sign rules in Section 16-15-12. Section 16-6-3-3(C) sets corridor-specific numeric limits for the remaining Areas E, F and G, applying whichever standard between Section 16-15-12 and the SOD is more restrictive: no sign or sign structure within 660 feet of the Freeway 61/151 right of way may be visible to a person of normal visual acuity traveling on the freeway, and in no event may a sign exceed 25 feet in height, 300 square feet in size, with a minimum 500-foot linear spacing between signs visible to oncoming traffic.
Section 16-6-3-3(D) allows the zoning board of adjustment to grant a variance increasing the height or size standards, or reducing the spacing requirement, for any lawful sign. All of these provisions trace to Ordinance 52-09, adopted October 19, 2009.
Violations & Fines
The zoning board of adjustment and Planning Services administer variance requests and sign compliance in the SOD; erecting an off-premises sign in a banned subarea, or exceeding the 25-foot height, 300-square-foot size or 500-foot spacing limits elsewhere in the overlay without a granted variance, is enforced as a Title 16 zoning violation subject to removal or correction orders.
