XF300 FIRE HYDRANTS
IFC Section 507.5.1
Where a portion of the facility or building hereafter constructed or moved into or within the jurisdiction is more than 400 feet (122 m) from a hydrant on a fire apparatus access road, as measured by an approved route around the exterior of the facility or building, on-site fire hydrants and mains shall be provided where required by the fire code official.
Exceptions:
1. For Group R-3 and Group U occupancies, the distance requirement shall be 600 feet (183 m).
2. For buildings equipped throughout with an approved automatic sprinkler system installed in accordance with Section 903.3.1.1 or 903.3.1.2, the distance requirement shall be 600 feet (183 m).
Title 17 of the King County Code requires buildings with footprints of 20,000 sq. ft. or more, or fire flow requirements of 3,000 gpm or more to have fire hydrants on all sides of the building, with approved fire lane access to serve them. This criteria is not met on this project. The alternative to providing the additional fire hydrants and access is to upgrade the building sprinkler system from NFPA 13R to full NFPA 13 throughout.
The locations of the fire hydrants are not shown and shall be located outside the building collapse zone. The sprinkler systems fire department connection (FDC), standpipe connection and post indicator valve (PIV) can also be located in the same area.
