Project Case Study: Treating Roof Runoff at the Source
In the late 1990s,the Puget Sound Regional Council concluded that its only option for expanding commercial aviation capacity was at Seattle-Tacoma (Sea-Tac) International Airport. But the Port of Seattle’s Aviation Division determined that construction of a third runway would encroach on wetlands, requiring control of both the quantity and quality of stormwater discharge.
Design and Analysis Software
The staff of CE News is pleased to present its annual product guide featuring stand-alone design and analysis software for a wide variety of civil engineering applications.
The software applications are divided into general categories, and each product’s specific functions and features are indicated. Please contact the developers directly to learn more about the products. We hope this information introduces you to new tools for your designs.
Parking Lots That Leak
Design of stormwater management systems is changing dramatically, with volume reduction by infiltration and water quality considerations dictating the methods and materials used. Porous asphalt pavements with sub-surface infiltration beds offer site planners and public works officials the opportunity to minimize impervious surfaces and manage stormwater in a cost-effective and environmentally friendly way.
Pumps, Valves, and Meters

New Orleans Drainage
Settled by the French in 1718 on high” ground between the Mississippi River and Lake Pontchartrain, New Orleans has battled flooding throughout its history. In the 19th century, a moderate rainfall was enough to flood parts of the city, often for as long as a week, according to the Sewerage and Water Board of New Orleans (SWBNO).
