A California Court of Appeal upheld denial of a petition by vintners challenging the prohibition on new vineyards within the Santa Monica Mountains Coastal Zone in deference to the California Coastal Commission’s finding that viticulture adversely impacts sensitive habitats, water quality, water supply, and scenic resources. Mountainlands Conservancy, LLC v. California Coastal Commission, No. B287079 (2d Dist., Apr. 1, 2020).
The California Coastal Act requires the California Coastal Commission to review and certify local coastal programs (LCP) developed by local authorities that control land use planning within their respective areas of the coastal zone. Los Angeles County proposed to amend the LCP for the Santa Monica Mountains Coastal Zone in a manner that would ban new agricultural uses. Commission staff recommended approval of the LCP with modifications that lightened restrictions on some new agriculture but retained the ban on new vineyards. Commission staff reasoned that the majority of land within the LCP area was “unsuitable” for agriculture, and new vineyards should “remain prohibited due to a number of identified adverse impacts attributed specifically to those operations, including increased erosion from removal of all vegetation, use of pesticides, large amounts of water required, their invasive nature, and their adverse impact to scenic views.”
The Commission unanimously voted to approve the LCP as modified and certified the LCP in October 2014. Landowners within the LCP area sued, contending principally that the Commission erred in failing to heed policies favoring the preservation of agricultural lands within the coastal zone and that there was insufficient evidence to justify its ban on new vineyards.
The Court of Appeal found no legal error in the Commission’s consideration of California Coastal Act policies requiring the Commission to maintain the “maximum amount of prime agricultural land . . . in agricultural production” and forbidding the conversion of other lands “suitable for agricultural use” unless “continued or renewed agricultural use is not feasible.” The court observed that the LCP fully protected existing agricultural production, including existing vineyards. It also noted that the California Coastal Act definition of “feasible” includes “economic, environmental, social, and technological factors” that the Commission properly considered in support of its finding that the LCP lands were mostly “unsuitable” for agriculture.
In response to the landowners’ further contention that new vineyards should be treated equally to other agricultural uses not subject to a total ban, the court found substantial evidence in the record supporting the special ban under the LCP. The court pointed to a UCLA Institute of the Environment & Sustainability report, which studied urbanization within the Santa Monica Mountains National Recreation Area and found that “[a]dditional vineyard development has the potential to severely disturb natural areas, which could result in fragmentation and loss of native species.” The court also relied upon administrative testimony from the Commission’s staff ecologist, who opined at the Commission hearing that new vineyards in the LCP area would threaten habitat loss, disrupt wildlife corridors, reduce biodiversity, and impact freshwater resources. Evidence of the economic feasibility of new coastal vineyards, such as federal recognition of the Malibu Coast American Viticulture Area, did not override competing environmental and ecological factors in the view of the Commission or the Court of Appeal.
