Thank you for the opportunity to provide a cursery review of the proposed site plan surrounding the
above named development project in preparation for a pre-application meeting. Tualatin Valley Fire &
Rescue has listed the following conditions that may apply.
FIRE APPARATUS ACCESS:
1. FIRE APPARATUS ACCESS ROAD EXCEPTION FOR AUTOMATIC SPRINKLER PROTECTION: When
buildings are completely protected with an approved automatic fire sprinkler system, the requirements for
fire apparatus access may be modified as approved by the fire code official. (OFC 503.1.1) Note: If
residential fire sprinklers are elected as an alternate means of protection and the system will be
supported by a municipal water supply, please contact the local water purveyor for information
surrounding water meter sizing.

roof surface that exceeds 30 feet in height shall be provided with a fire apparatus access road constructed for use by
aerial apparatus with an unobstructed driving surface width of not less than 26 feet. For the purposes of this section,
the highest roof surface shall be determined by measurement to the eave of a pitched roof, the intersection of the roof
to the exterior wall, or the top of the parapet walls, whichever is greater. Any portion of the building may be used for
this measurement, provided that it is accessible to firefighters and is capable of supporting ground ladder placement.
