Change to Design
EHLF Code Research
The Federal Aviation Adminitration (FAA) was consulted to verify that an evaluation for the rooftop was not necessary due to the function of the emergency helicopter landing facility (EHLF) prohibiting personal and private use of the helipad. Likewise Caltrans Division of Aeronautics did not require a permit due to the landing pad solely operating for emergencies. Los Angeles City Fire Department code was adhered to when implementing fire hose cabinets and adequate flammable liquid drainage. The California Building Code was used to design for a non-combustible construction and the dimensions of the EHLF.
EHLF Design Plans
To ensure that the Irvine Streamline's Emergency Helicopter Landing Facility (EHLF) complied with the federal and city codes, the design team were able to include the safety zone surrounding the Touchdown and Liftoff area (TLOF) whilst maintaining at least 50% of the green roof to ensure no point deductions based on LEED v4 BD+C criteria.
