ATTY/RESO.0086/PC RESO RECOMMENDING APPROVAL OF ZA AMENDMENT – 1616 GORDON STREET REV: 10-13-2021 VR Page 19 of 21 a. The revised plans indicate ladder pads adjacent to the building. They need to be setback from the building to achieve a 75 degree climbing angle. i. The plans indicate that the ladder pads are set back 4 feet from the building. b. Defined paths of travel for firefighters to be able to carry ground ladders to each ladder pad are provided by means of a walking path on one side but no defined clear path of travel on the other side. c. The requirement for emergency escape and rescue windows and therefore ladder pads may be eliminated if a more fire resistive construction type such as Type IIIA as well as an NFPA 13 compliant fire sprinkler system is utilized. 47. Available Water Supply to Project Site - Provide current fire flow information from the water purveyor to indicate the maximum available water flow in gallons per minute (GPM) at a minimum of 20 pounds per square inch (psi) residual pressure from the available fire hydrants. This information must be current and dated within a year. [COA][FIRE] a. Based on the proposed construction type of Type VA, and a square footage of 42,929, the required fire flow is 3,750 GPM at 20 Psi residual pressure. The Redwood City Municipal Code Section 12.16, allows for a maximum reduction in fire flow based on the installation of automatic fire sprinklers meeting section 903.3.1.1 (NFPA 13) of the CFC of 50% making the required fire flow 1875GPM at 20Psi residual pressure for this project. b. The required fire flow would be reduced to 1500 GPM if the building construction type was changed to Type IIIA. 48. Fire Hydrants - Based on the required fire flow for this project, the number of fire hydrants and the required distance between them and to the property lines will be determined utilizing Appendix C of the CFC. [COA][FIRE] 49. Automatic Fire Sprinkler – The building is required to be equipped throughout with an automatic fire sprinkler system meeting all of the requirements in NFPA Standard 13. Provide plans and hydraulic calculations for the design of the system CFC 903.2.13. [COA][FIRE] 50. Fire Department Connection – FDC’s to the fire sprinkler system shall be located at the fire access side of the building within 50 feet of a Fire Hydrant on the same side of the road CFC 507.5.1.1.
