  • A mini-series following my 44mm-high “Homies” character Pelon, where he poses for photo ops at potholes on the streets of Mount Tabor Park.<br />
Leadership fixes potholes, not patching.<br />
Chronic neglect of Portland’s streets is manifesting in the burgeoning number and size of dangerously large potholes across the city.  Here, pothole road damage is seen in Mount Tabor Park, Portland, Oregon. <br />
Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case.  Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  The asphalt layer is minimal,  confirming this road never received the maintenance originally planned. The river-rounded pebbles of the base course layer tell the story of a roadway constructed originally from deficient materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock – a crushed and sieved mix from those same pebbles would suffice.  Finally, from the moisture visible in the pothole, and the shape of terrain at the road shoulders, it is clear that poor drainage has contributed to the failure of this road.  The conclusion is unequivocal; this road has failed and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

The size variation of aggregate chunks in the base course layer tells the story of a roadway constructed originally from well-graded materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  The breakup of pavement behind and to the left of Pelon – at the gutter – suggests that poor drainage played a role in this failure, and absence or repair has allowed water to saturate the base layers and complete the failure.  This road has failed due to neglect and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case.  Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  At this pothole, the asphalt layer is thick; confirming this road has received an overlay, but perhaps covering up this pothole without first repairing it. The base course layer is hard to characterize because the quantity of water present. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  This dangerous pothole, in the traveled way and where pedestrians cross, can be repaired by cutting out and reconstructing, but simply patching or overlaying will rapidly lead to a repeat failure, preventing a level of service – or service life – that should be reasonably expected of it.<br />

  • Reservoir 5 at Mt Tabor Park was emptied by Portland Water Bureau in October 2022, to check for leaks in the liner, seen here. Reservoir 5 (1911) is one of three open reservoirs at Mount Tabor Park and of five total in Portland.  Mount Tabor's three open reservoirs and their ancillary structures were placed in the National Register of Historic Places in 2004.  The Environmental Protection Agency (EPA) 2006 regulation known as the Long Term 2 Enhanced Surface Water Treatment Rule (aka the LT2 Rule) imposed new requirements that open water reservoirs be covered, buried or additionally treated.  This applies to Portland's five open reservoirs and to the unfiltered Bull Run source supplying them. These requirements could not practicably be met while maintaining these open reservoirs, and in 2016 all of the reservoirs at Mount Tabor were finally taken offline and permanently disconnected from Portland’s drinking water system.

  • Celebration of Mount Tabor Park, one of the oldest urban parks in the United States.  Located on an extinct volcanic cinder cone, and designed in 1909 by Emanuel T. Mische and John Charles Olmsted, this urban park incorporated working open water reservoirs, a vital link to bringing fresh, high-quality drinking water from Bull Run to the Portland area.  These reservoirs have been condemned by new EPA regulations, and plans are already in progress for their elimination from the water distribution system.  Standard format – 8.5" x 11" (217mm x 280mm) – full color.  All photos © Andrew Haliburton.
