Originator City of Portland
Bureau Portland Fire & Rescue
Publication Date
Abstract Alternate water sources that can be drafted from for Portland Fire & Rescue apparatus. Consists of river access via boat ramps, hydrants connected via water mains to tanks, ponds/lakes, and public swimming pools. In a post-earthquake event, none of these sites can be guaranteed as reliable alternate water sources. Data is projected in NAD_1983_HARN_StatePlane_Oregon_North_FIPS_3601_Feet_Intl.
Purpose To be used as reference in case of a large scale disaster that compromises the City's water system, preventing most hydrants from being a point of distribution. In a post-earthquake event, none of these sites can be guaranteed as reliable alternate water sources.

Tank sites obtained from Water Bureau (4/2016). There is no direct way to pump from a tank. Hydrants connected to tanks through water mains were selected as possible reliable sources for tank water. There is no guarantee from the Water Bureau that the tank contains water.Pond and Lake sites obtained from Water Bureau – (4/2016). Some ponds and lake sites owned by Parks and Recreation Department were included if they seemed reasonably accessible to fire apparatus (w/i 20 to 40 feet vertical/horizontal reach). Boat ramp sites obtained from State of Oregon open data (6/2016). Downloaded from data.oregon.gov. Boat Ramp sites were narrowed down to just those sites along the Willamette, Columbia and other water bodies that had concrete/driveable access up to the water’s edge.Public swimming pool sites owned by Parks and Recreation Department or Swimming Districts obtained from Google Maps search. KML was downloaded from Google My Maps and incorporated into the dataset (4/2016). Ponds on Golf courses owned by Parks and Recreation Department obtained from Google Maps search.
