  • Channel drain detail of stormwater facilities, Tanner Springs Park, Portland, Oregon.  This park in the Pearl District of downtown Portland, Oregon is a modern-day experiment in sustainable design and stormwater management.  The water feature, designed by Herbert Dreiseitl is an effort to re-create the pre-industrial wetlands and riparian ecology of the original Tanner Creek that flowed to the nearby Willamette River in the early 1800s.  One sustainability feature of the park is the collection, treatment and recirculation of all rainwater that falls within the park.  Additional sustainability features include the re-use of basalt cobbles, or Belgian Blocks, for walkways and the re-use of rusty railroad rails for the undulating wall.

  • 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.

  • Continuous pumping is required from a system of channels and dikes around the Salton Sea to limit flooding of farmlands, a wildlife refuge and nearby geothermal energy plants.  The Sonny Bono Salton Sea Wildlife Refuge (EL -227ft) is located along the course of the Pacific Flyway in the Imperial Valley of California.  Flooding by the Salton Sea has reduced the manageable area from 36,700 acres to 2,200 acres.  The dikes now limit further encroachment.

  • The Astoria-Megler Bridge (1966) spans the mouth of the Columbia River between Astoria, Oregon and Point Ellice near Megler, Washington. The bridge type is a steel cantilever through truss, designed jointly by the state highway departments of Oregon and Washington. Construction was started in 1962 and completed in 1966.

  • FEC New River Bridge (1978) is a single-leaf bascule railroad bridge spanning the navigable New River in downtown Fort Lauderdale. The design type is a through plate girder bridge of total span 70 feet /21.3m, providing a horizontal boat navigable clearance of 60 feet/18.3m. Additionally, the bridge comprises three 25-foot approach spans, plus a 14-foot machinery room span, from the north; and two 25-foot spans from the south. Notable was the use of weathering steel to eliminate environmental concerns around initial and future painting. By 1985, the weathering steel had reportedly reached a stable condition for its environment. One of the design criteria for this bridge was to double-track the crossing, removing the bottleneck of a single track bridge at this location dating back to 1912. Now, in the 21st Century, as freight trains are once again sharing the tracks with passenger trains operated by Brightline, alternatives are being studied through the New River Crossing Feasibility Study to further expand capacity by tunnel and various fixed/movable bridge replacement options.

  • Clay Shaw Bridge (2001), also called the 17th Street Causeway Bridge, is a pair of twin parallel 54-foot-wide causeway structures, each incorporating a double-leaf bascule bridge, separated by a 13-foot open air median. This new bridge, spanning 210 feet between trunnions, increases navigable waterway width of the Intracoastal Waterway from 100 feet to 125 feet, and vertical clearance from 22 feet to 55 feet, over the previous 1956 bridge at this location – the Commodore Brook Memorial Causeway. Striking features of this bridge are its V-shaped Carina piers (providing excellent visibility for shipping navigation) and the Art Deco-style bridge operator’s house. Also notable are the open traffic railings (for greater vista visibility), emergency shoulders, bicycle lanes and sidewalks – with pedestrian overlooks incorporated into the bascule spans. Owner: Florida Department of Transport; Design consultant for piers and bascule bridge: EC Driver & Associates; Design of Bridge Structures: FIGG Bridge Engineers; Roadway: Keith & Schnars.

  • The Morrison Bridge (1958) viewed through spans of the Burnside Bridge (1926), both spanning the Willamette River in downtown Portland. Both bridges are double-leaf bascule drawspan bridges, the distant bridge (Morrison) being approximately three decades more modern in design. Portland, Oregon USA.

  • Burnside Bridge (1926) comprises a double-leaf bascule drawbridge main span, flanked by longer riveted double-intersection Warren deck truss approach spans. The bridge has long multi-beam steel deck girder approach spans bridging railroad tracks, freeways and city streets of downtown Portland, while the main span bridges a fetch of the Willamette River navigable to full-size commercial shipping. This bridge replaced the original 1894 wrought iron truss steam-powered swing-span bridge, two spans of which were repurposed as the current Bull Run River Bridge and Sandy River Bridge on Lusted Road, both in neighboring Clackamas County. Striking features of this bridge are its riveted double-intersection (lattice) Warren trusses featuring intermediate sub-verticals – an uncommon truss configuration, and its ornate bridge operator’s houses. The bridge was designed by Gustav Lindenthal and Joseph Strauss. Other notable features are its hidden below-deck counterweights, ornamental concrete balustrade railings, and fine metal railings on the lift spans. This bridge has great historical significance. Multnomah County, Oregon, USA.

  • Snow-Reed Bridge (1925) is the oldest bridge in Fort Lauderdale, and the last operational swing span bridge surviving in South Florida. In 1989, 64 years after construction, it was designated a historic landmark and renamed from the Southwest 11th Avenue Bridge to Snow-Reed Bridge, for the two mayors whose terms spanned its 1924-5 construction. The bridge spans the North Fork of the New River and was constructed on the north-south alignment of SW 11th Avenue, connecting the neighborhoods of Riverside and Sailboat Bend. The structure is a Warren Pony Swing Metal Truss – the Pony part being simply a through truss that lacks overhead cross-bracing between the top chords. Nice cantilevered sidewalks appear to have been added at some point. The bridge has no practical vertical clearance, while it obstructs a navigable river, so an on-site bridge operator is required 24/7. A one-year major renovation ending in 2010 added a new octagonal-shaped bridge tender control house while retaining and restoring the original bridge tender’s house. Notable also is this old bridge’s vulnerability to sea-level rise; its swing mechanics are set just inches above sea water tide levels, so the mechanics are repeatedly submerged in salt water. Broward County, Florida, USA.

  • This image, "Ebb Tide, Columbia River, Astoria" was previsualized.  But what wasn't anticipated was the constant rain.  Working in the pre-dawn darkness, I had to hold an umbrella with one hand while setting up tripod and camera with the other.  The Astoria-Megler Bridge (4.1 mi / 6.5km long) spans the mouth of the Columbia River between Astoria, Oregon and Point Ellice near Megler, Washington. Construction was started in 1962 and completed in 1966.

  • Tanner Springs Park in the Pearl District of downtown Portland, Oregon is a modern-day experiment in sustainable design and stormwater management.  The water feature, designed by Herbert Dreiseitl is an effort to re-create the pre-industrial wetlands and riparian ecology of the original Tanner Creek that flowed to the nearby Willamette River in the early 1800s.  One sustainability feature of the park is the collection, treatment and recirculation of all rainwater that falls within the park.  Additional sustainability features include the re-use of basalt cobbles, or Belgian Blocks, for walkways and the re-use of rusty railroad rails for the undulating wall.

  • 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.
