By Larry Trojak As the benefits of a comprehensive GIS effort have become more and more apparent, larger cities and municipal utilities have been steadily getting on board with the technology, citing it as something of a no-brainer in terms of better asset availability, increased accuracy, ease of access to information, and so on. Smaller towns and cities, however, have been reluctant to make the same move, often citing it as both too daunting and far too cost-prohibitive. The City of Troutdale (OR) Dep...... 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 The O’Hare Modernization Program (OMP) is transforming O’Hare International Airport’s airfield from an outdated system of intersecting runways into a mode......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

Last summer, the Virginia Department of Conservation and Recreation, the Department of General Services, the city of Richmond, and the Alliance for the Chesapeake Bay completed a green stormwater retrofit of Virginia’s Capitol Square. As have other states in the Chesapeake Bay watershed, Virginia has paid increasing attention to the quality and quantity of its runoff in recent years. With this project, the state government has taken the lead, demonstrating that low-impact development can be an effective...... continue reading

In 2008 the British Columbia Utilities Commission (BCUC) granted a Certificate of Public Convenience and Necessity for the Ruskin Dam and Powerhouse Upgrade Project. Treating the stormwater runoff from this construction project is a huge challenge. Not only does the project area encompass a large amount of acreage, it is also situated in a very sensitive salmon habitat and is an extremely high-profile project in the public eye. The system of treatment chosen must treat the turbid water without failure, ...... 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 Mike Vaughan Spectators from around the globe have been watching the London 2012 Olympic and Paralympic Games, enthralled by world-class athletes participating in stunning competitions. It’s a safe bet to imagine that few in the crowd have thought about flooding, though flood safety was an essential factor in the creation of the new Olympic Park, site of Olympic Stadium and numerous other competition venues. To keep floodwaters controlled, 2 miles of riverbanks were redesigned and reengineered...... continue reading

By Angus W. Stocking The town of Palm Beach, FL, is located on a long, narrow barrier island 65 miles north of Miami and is well known for its many multimillion-dollar mansions. The expensive real estate and the ever-present saltwater are major complications for the Public Works Department; saltwater corrodes everything, and digging things up for repair is always costly. Therefore, maintenance and trenchless methods are high priorities, and the department is always alert for new technologies. As ...... 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
