In a developer's suit against the City of Los Angeles for rejecting as incomplete an application for conversion of its mobilehome park because the application failed to include an application for clearance under the Mello Act and an application for a coastal development permit under the Coastal Act, trial court's entry of judgment directing issuance of a peremptory writ of mandamus commanding the city to deem plaintiff's application complete is reversed and vacated as, in light of the paramount concern for protecting coastal resources by regulating development as expressed in the Coastal Act, section 66427.5 does not preclude the city from imposing conditions and requirements mandated by the Mello Act and Coastal Act on a subdivider seeking to convert to resident ownership a mobilehome park located in the coastal zone.
