Background
Laguna Beach’s general plan Policy 14-B prohibits hillside development on slopes of 45 percent or greater. The plan defines slope as rise divided by run, expressed as a percentage, but does not identify the points between which those distances must be measured. The municipal code separately defines “slope in percent” using average elevations at the front and rear property lines and the lot’s average depth; although adopted in a 1989 building-height ordinance, it appears in the zoning title’s general definitions and is not expressly limited to height calculations.
Owners proposed a custom home on a sloping Laguna Beach parcel in 2017. Revised 2022 plans listed a 32.6 percent lot slope, and the Design Review Board approved construction. Neighbors appealed to the City Council, initially emphasizing driveway and fire-access concerns without citing Policy 14-B or supplying a slope calculation. The day before the hearing, their architect asserted slopes of 62 to 100 percent. At the hearing, the city planner presented an approximately 36 percent average-lot-slope calculation, and councilmembers, neighbors, the architect, and the Coalition’s future counsel extensively debated averaging, property lines, and footprint slopes. The Council denied the appeal four to one.
The Coalition petitioned for a writ of mandate, alleging the site was too steep under the general plan. The trial court allowed supplemental briefing, granted the petition, found the Council fairly apprised of the slope issue, rejected the City’s municipal-code methodology, found the only proper record evidence showed a 91 percent slope, and directed the City to set aside its approval. The City appealed. The Court of Appeal granted the Coalition’s judicial-notice request only as to the Land Use Element and Ordinance No. 1187 and denied the remaining requests.
The Court’s Holding
The Court of Appeal held that the Coalition largely exhausted its administrative remedies. Although the notice of appeal and attached letters did not specifically invoke Policy 14-B, the slope issue was front and center: the planner introduced his calculation, councilmembers repeatedly sought clarification, and opponents presented competing measurements. Applying the administrative “fairly apprised” standard rather than judicial-level specificity, the court found no unfairness to the City despite a code provision limiting certain appeals to stated grounds. A footnote flagged, without deciding, whether the Coalition’s later 86 percent calculation was exhausted.
On the merits, the court reviewed the City’s general-plan consistency determination for prejudicial abuse of discretion and deferred unless no reasonable person could reach the same conclusion. It found the City considered Policy 14-B, at least implicitly made the consistency finding, and supported that finding with the planner’s 36 percent calculation. The general plan’s slope definition was mandatory but incomplete because it did not specify which points to use on a three-dimensional hillside with contours, cross-slopes, and level areas.
The court criticized both sides: the Coalition offered at least ten different calculations, while the city planner relied rigidly on the code without working through the front- and rear-lot-line definitions. But the street-facing explanation and the City’s consistent averaging procedure made the method reasonable rather than unreasonable. The court therefore reversed, directed the trial court to vacate its judgment and enter a new judgment denying the writ petition, and awarded the City costs on appeal.
Key Takeaways
- An administrative appellant need not state an issue with judicial precision when the agency was fairly apprised and had an opportunity to evaluate and respond.
- Laguna Beach’s general plan defines slope through rise and run but does not specify which points on a three-dimensional parcel must be used for those measurements.
- The City’s approximately 36 percent calculation supported its implicit general-plan consistency finding under the deferential abuse-of-discretion standard.
- The appellate court did not endorse the City’s method as the only reasonable approach; it held only that the method was not unreasonable on this record.
- The judgment granting the writ was reversed with directions to vacate and deny the Coalition’s petition, and the City was awarded its costs on appeal.
Why It Matters
The decision separates preservation of a land-use objection from success on that objection. Extensive agency consideration can satisfy exhaustion even when the initial appeal papers are imprecise, while the merits remain subject to substantial deference to local general-plan consistency findings. The exhaustion footnote also identifies, without resolving, a potential problem with calculations introduced only during later judicial briefing.
The ruling is record-specific and unpublished. It does not establish a universal slope-measurement rule or require expert evidence in every case; the court expressly set no hard-and-fast rule. Its practical point is that an incomplete general-plan formula, varied topography, and a consistently applied municipal methodology left room for a reasonable local determination.
