[CFC Appendix D§105.1] F7. Required Fire Flow: Based on the proposed construction type of Type III-A, at <br />94,925 square feet, the required fire flow for this project is 4,500 GPM at 20 psi residual pressure. After allowing for a 50% reduction due to the installation of automatic fire sprinklers meeting section 903.3.1.1 of the 2019 CFC (NFPA 13), the required fire flow for this project is 2,250 GPM at 20 psi residual pressure. [CFC §507.1] Based on the required fire flow of 2,250 GPM at 20 psi residual pressure, the required number of fire hydrants is two with a spacing of 450 feet in accordance with Appendix C of the CFC.

Alternate Source of Power: Notwithstanding the availability of a public utility to provide electric service for a fire pump, electrically driven fire pumps must be provided with an alternate source of power in accordance with NFPA 20 due to foreseeable extended electrical service interruptions along the California Power Grid due to high demand, high heat, Public Safety Power Shutoffs, or damage to the power grid caused by destructive natural events such as wildfires, high winds, and earthquakes. [CFC §913.2.3 and the Redwood City Municipal Code §12.24.1] The alternative source of power may be supplied with fuel in the form of diesel, natural gas, or LPG. F10.
