  • Rain garden manages stormwater runoff at Mt Tabor Middle School.  Partnership of the school, Portland Public Schools and Environmental Services built the rain garden to reduce storm flows to the public sewer line.  Sediments and pollutants are removed before the water gradually soaks into the ground.  A 10-year maintenance agreement has been signed.

  • Public art waterfall fountain entitled Spawning (2000), by Pat Tamley & Engineering Services, City of Richmond B.C.  The spawning salmon within the waterfall relate to Richmond's fishing heritage and strong ties to the Fraser River.  The male salmon exhibit the 'kype' (or hooked nose) that is developed when the fish enter fresh water to spawn. River Road near Richmond Olympic Oval.  ICE Americas Convention.

  • Landscaped stormwater planter strip manages rain water from the "first flush" during a rainfall event.  Stormwater has filled the first chamber and is overtopping a weir and filling the second chamber.  Green streets collect stormwater runoff and route it through facilities like this planter where vegetation and soils filter pollutants before allowing water to soak into the ground.  These facilities replenish groundwater and enhance neighborhood green spaces.  Green streets require routine cleaning and maintenance.  This facility is on NE 47th Avenue at NE Davis Street in Portland, Oregon.

  • Vegetated Filter Strip treats rain water runoff from parking lot before it reaches a swale which in turn discharges the stormwater into a nearby stream.   Vegetated filter strips are now a widely accepted best management practice (BMP) for low impact development.  They work on the principle of contact time and therefore require low runoff velocities.  This is achieved by maintaining low-angled slopes and avoiding flow-concentrating features such as curbs.

  • The First Regiment Armory Annex, commonly known as the Portland Armory Building, at 128 NW 11th Avenue.  The building was renovated from 2002 to 2006 (to LEED Platinum certification) and now houses the Gerding Theater, used primarily by the theatre group Portland Center Stage.   The adjacent Vera Katz Sidewalk Park, or Sliver Park, includes a bioswale for stormwater treatment and a water channel of sculpted black basalt.  The water feature design, by Scott Murase of landscape architect firm Murase Associates, is part of the building's storm water management and is fed by roof runoff.

  • 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 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 />

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 />

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 />

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 />
