GENERAL COMMENTS
G-0002 Alternate Method
The Lake Oswego Fire Marshal has determined that water supply and/or fire apparatus access are
inadequate for any portion(s) of this site, accordingly the Building Official will allow for the consideration of
Uniform Alternate Construction Standards (UACS) per OAR 918-480-0125. Due to the urban environment
of the City of Lake Oswego, the most likely UACS determination by the Building Official will be, at minimum,
option (4)(a), installation of a NFPA Standard 13D fire suppression system.
