Brookview Ranch, LLC (Brookview Ranch, or Brookview), the Owner of Brookview Ranch and the Applicant, seeks a Significant Ecological Area (SEA) Conditional Use Permit (CUP) from the County of Los Angeles (County) Department of Regional Planning (DRP) to convert an existing outdoor dance pavilion used for outdoor weddings into an event facility with a sound-insulated event facility reception building and ancillary structures, reconstruct structures damaged in the 2018 Woolsey Fire, install an access bridge over Triunfo Creek, and improve water and wastewater infrastructure on 23 acres of land. The proposed Project site is currently used as an outdoor dance pavilion and equestrian facility. It contains outdoor dance pavilion facilities, equestrian barns, and ancillary structures associated with the outdoor dance pavilion, equestrian uses, or both, as well as a Caretaker’s Residence. Twenty-one structures that support these uses are located on the proposed Project site with two structures damaged by the 2018 Woolsey Fire to be reconstructed as part of the proposed Project. Of the total proposed Project site building area of 54,150 square feet (sf), 7,907 sf support the outdoor dance pavilion uses; 45,120 sf support the equestrian uses; and 1,123 sf comprise the Caretaker’s Residence. The proposed Project would demolish five existing structures. In the same location as some of the structures that would be demolished, the proposed Project would construct a sound-insulated event facility reception building. The proposed Project would also construct a new Caretaker’s Residence in the same location as the existing Caretaker’s Residence and replace the Bride’s Dressing Room and a horse barn that were damaged in the Woolsey Fire. At proposed Project completion, there would be 20 structures on the proposed Project site, with a total of 55,557 sf. Of the proposed Project site building area, 8,891 sf would support the event uses; 43,342 sf would support the equestrian uses; and 3,324 sf would comprise the Caretaker’s Residence.
