A sufficient number of hydrants shall be installed to concentrate the required fire flow within 400' of any structure. Hydrants shall be placed at least 50' from the structure being protected. Where this is not possible, they shall be placed where the possibility of injury from building collapse is limited. Installation locations shall be approved by the Fire Prevention Bureau. Any changes or relocation of fire hydrants from the approved hydrant location plan shall be approved by the Fire Prevention Bureau prior to installation or relocation. Streets with medians of more than four lanes of traffic shall have hydrants placed on each side of the median so that fire lines will not have to cross the street. Tactical considerations may require additional hydrants and will be considered on a project-by project basis. Onsite hydrants shall not be connected to the fire sprinkler system. When any portion of a building is more than 150 feet from a fire hydrant provided on a public street, onsite hydrants capable of providing the required fire flow will be required.

NOTE: Fire flows listed are guidelines and specific projects may require different fire flows depending on occupancy, size, and construction of a particular building.
