By Carol Brzozowski Damaged pipes pose a host of problems, from significant maintenance costs to environmental threats. Many communities throughout North America have been mitigating those problems in such a way that minimizes costs, traffic interruption, and maximizes on the longevity of newer materials and repair methods. Stoney Creek In Oakland Township, MI, a pipe arch culvert that allowed Stoney Creek to pass underneath Stoney Creek Road had corrosion and was exhibiting various signs of distress du...... continue reading

By James McRay If the saying goes, “The whole is more than the sum of its parts,” then all those parts must absolutely be important in creating a dynamic final product. This adage is especially true at Chicago’s O’Hare International Airport, one of the world’s busiest, which is in the midst of one of the country’s largest construction projects. The O’Hare Modernization Program (OMP) is transforming O’Hare International Airport’s airfield from an outdated system of intersecting runways into a mode...... continue reading

By Don Talend Handling Wet, Emergency Conditions The intersection of Routes 9 and 440 with the Garden State Parkway is one of New Jersey’s busiest and most vital cloverleaf complexes. Sinkholes began to appear there after Hurricane Irene in 2011. “Soil was collapsing into large-diameter corrugated metal pipe [CMP] storm sewers and creating big sinkholes,” notes Alkesh Desai, stormwater emergency manager for the New Jersey Department of Transportation (NJDOT). “When we inspected, we found that mor...... continue reading

By Angus W. Stocking Smuggler’s Notch ski resort, near Jeffersonville, VT, was established in 1956 and is New England’s fourth-largest resort area. It is built around Morse, Madonna, and Sterling mountains. Record storms in the Northeast, and the resulting record snowmelt, caused near-flooding at Smuggler’s Notch, and two 72-inch “boilerplate” culverts, each 130 feet long, were filled to near capacity with fast-moving water. They survived but were damaged; it was clear to managers that the culver...... continue reading

By Don Talend Back in the late 2000s, the city of Portland, ME, faced a situation that is not uncommon for a Northeastern municipality: separating sewage and stormwater flows, and replacing very old infrastructure in the process. The $4 million West Side Interceptor combined sewer overflow abatement project replaced 100-year-old 24- and 30-inch-diameter vitrified clay line with 60-inch-diameter, high-performance polypropylene pipe. Additionally, the project created a parallel 10-foot-diameter lin...... continue reading

By Margaret Buranen Seattle’s Thornton Creek Water Quality Channel (TCWQC) does more than manage stormwater. This innovative project catalyzed over $200 million in development that revitalized an aging neighborhood. The American Society of Landscape Architects (ASLA) named it one of the best projects of 2010. TCWQC “not only improved water quality, but also reconnected people with Thornton Creek in a new transit-oriented urban setting with residence, jobs, and recreation, and created new open spa...... continue reading

By Janis Keating Piping systems have existed for millennia; ancient Crete made its from terra cotta, a material that’s still used today. When the Romans discovered how to refine lead, the element was employed in piping systems. (The word plumber derives from the Latin term for lead: plumbum .) Later manufacturing discoveries added iron, steel, and concrete to plumbing’s repertoire; when high density polyethylene plastic (HDPE) was developed in 1951, it, too, found work in the piping industry. Creating a...... continue reading

Flooding can be caused by heavy rain falling for an unusually long time. It can be caused by an unusually large snowpack followed by a sudden thaw. It can be caused by unusually high tides, tsunamis, dam failures, deforestation, poor drainage, or a high proportion of impervious land, or by a combination of any of these factors. Because the most vulnerable areas are low-lying, the first method of flood control is often to build berms, levees, and floodwalls. Another is to dig down and construct ponds and...... continue reading

With development occurring at a rapid rate in many parts of the United States and across the globe, stormwater experts are grappling with ways to deal with increased runoff and water-quality problems. More than half the rain that falls on some developed areas may become runoff, and during intense storms, the runoff in these areas can lead to flash flooding. Use of detention ponds has become a best management practice in urbanizing areas to deal with both water-quantity and -quality issues. But designing...... continue reading

By Lalit Jha, Devin Biesecker, Jonathan E. Jones, J. D. Johnson, and Sally Kribs Virtually every municipal public works staff person has had the experience: Heavy rains are followed by calls from certain residents on particular streets complaining about drainage issues. Oftentimes these “squeaky wheels” have their concerns addressed far sooner than other potentially more serious municipal drainage problems that are not the subject of complaints. In fact, frequency of resident complaints is commonly...... continue reading
