Re: Greenburg Apts
Thank you for the opportunity to review the proposed site plan surrounding the above named development
project. Tualatin Valley Fire&Rescue endorses this proposal predicated on the following criteria and conditions
of approval:
1) FIRE APPARATUS ACCESS ROAD DISTANCE FROM BUILDING AND TURNAROUNDS: Access roads
shall be within 150 feet of all portions of the exterior wall of the first story of the building as measured by an
approved route around the exterior of the building. An approved turnaround is required if the remaining
distance to an approved intersecting roadway, as measured along the fire apparatus access road, is greater
than 150 feet. (OFC 503.1.1)
2) DEAD END ROADS: Dead end fire apparatus access roads in excess of 150 feet in length shall be
provided with an approved turnaround.(OFC 503.2.5)
3) FIRE APPARATUS ACCESS ROAD EXCEPTION FOR AUTOMATIC SPRINKLER PROTECTION: W hen
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.
4) ADDITIONAL ACCESS ROADS—COMMERCIAL: Where buildings exceed 30 feet in height or three
stories in height shall have at least two separate means of fire apparatus access. Buildings or facilities
having a gross area of more than 62,000 square feet shall be provided with at least two separate means of
fire apparatus access. Buildings up to 124,000 square feet provided with fire sprinklers may have a single
access.(OFC D104) The fire code official is authorized to modify Sections 503.1 and 503.2 where the
following applies:If fire apparatus access roads cannot be installed because of location on property,
topography, waterways,nonnegotiable grades or similar conditions an exception can be made if an
approved alternative means of fire protection is provided.
5) AERIAL FIRE APPARATUS ACCESS: Buildings or portions of buildings or facilities exceeding 30 feet in height
above the lowest level of fire department vehicle access shall be provided with approved fire apparatus access
roads capable of accommodating fire department aerial apparatus. Overhead utility and power lines shall not be
