Full Breakdown
The Implementing Zoning Ordinance's off-street parking chapter sets the baseline standards for every parking facility in the city. 070(E), "Parking in Required Yards," flatly prohibits parking areas in the required front setback or required street-side setback for any use other than single-family residential, residential duplex, or bed and breakfast structures; those three residential use types are the only ones the code exempts from the front-yard and street-side parking ban. 070(F), "Permanent Surface," applies to every parking area, aisle, and access drive in the city without the residential carve-out: each must be constructed and maintained to provide a durable, dustless surface, and must be graded and drained so surface water does not damage private or public property, streets, or alleys.
Gravel, dirt, or other non-durable surfaces that pond or wash water onto a neighboring lot or the public right-of-way fail this standard on their face. 070(D) caps driveway gradient at 15 percent (18 percent in hilly areas) with no more than a 12 percent rise or 8 percent decline change over any 30 linear feet. 080. 010.
Violations & Fines
Under Section 26.020(A), any parking use or structure set up, altered, enlarged, or maintained contrary to the Implementing Zoning Ordinance is declared unlawful and a public nuisance. Upon City Council order, the City Attorney must commence abatement, removal, and injunction proceedings, and courts may restrain any person, firm, or corporation from continuing the violation. Remedies are cumulative, not exclusive, so the city can pursue nuisance abatement alongside other code enforcement action for the same paved-surface or setback violation.
