SilverWing v. Bonner CountyAnnotate this Case
This appeal stemmed from a dispute between SilverWing at Sandpoint, LLC (“SilverWing”) and Appellant Bonner County, Idaho (the “County”). SilverWing sought to develop a residential hangar and taxiway adjacent to the Sandpoint Airport for residents who wished to park their aircraft in their home garage. SilverWing alleged that “[i]n 2007, the County provided to SilverWing an ALP that reflected the existing location of the Airport’s runway, and made no mention or reference to any plans for the runway to be moved. At the same time, the County promised that there were no plans regarding changes to runway location which would be incompatible with SilverWing’s development.” During the initial stages of engineering for the development, the County informed SilverWing that it needed to move the taxiway from where it was originally planned onto County-owned airport property, to accord with the County’s Airport Layout Plan (ALP). SilverWing proceeded with its development based on the County’s assurances, and built a taxiway and other infrastructure, including streets, to support its development. Once the taxiway was built, SilverWing learned that the placement of the taxiway was not approved by the FAA. After several years of legal maneuvering, SilverWing proceeded against the County in court, ultimately on a theory of promissory estoppel. After trial, a jury returned a verdict in favor of SilverWing. The County filed a motion for judgment notwithstanding the verdict (“JNOV”), which the district court denied. The County appealed. The Idaho Supreme Court reversed the district court’s ruling on the JNOV and vacated its ruling regarding attorney fees. The Court determined the district court erred with respect to JNOV on the claim of promissory estoppel: "SilverWing actually got what it claims the County promised—an FAA approved taxiway in the location where SilverWing built it. SilverWing can now sell its development with no regulatory uncertainty."
