Ocean Lakes issued the following statement on its Facebook page Sunday morning:

“We want to let everyone know the FACTS about the fire this morning at Ocean Lakes, there is a lot of misinformation. Most importantly, no one was injured (guests, homeowners, team on site to fight fire). One homeowner struggled with smoke and was administered oxygen and is being monitored. HCFR was called at 6:09 AM. Security was on site to inform and direct emergency responders as they arrived and assisted homeowners impacted by the fire.

“ALL homeowners whose sites have been visibly impacted have been notified, we cannot release those site numbers. FACTS: 2 sites destroyed, 1 heavily damaged, 8 others impacted (mainly due to heat such as siding). HCFR has control as fire is diminished and is on site to continue hot spot monitoring and keep under control. PLEASE avoid the area; barricades and caution tape are there for everyone’s safety! PLEASE respect the homeowners’ property. Our team is assisting the 3 permanent residents impacted. Your kind thoughts and prayers are appreciated.”
