Along Interstate 69 in Indiana Keeping Soil Onsite Strategies for construction-site management BY MARGARET BURANEN Reclaiming an Airport Site Denver, CO, is the location of one of the largest urban infill projects in the nation, and erosion control is a big part of the project. The construction that has been going on there for several years is on the site of Denver’s former airport, Stapleton International. Denver outgrew this airport, which was named for a former mayor. The facility was closed in February 1995 and replaced by Denver’s new International Airport. Once the concrete from the old airport’s runways had been removed and recycled, some roads and other infra-structure were added. Then the 4,700 acres were ready for site development preparation work for the thousands of homes (and churches, schools, and shopping centers) to be built there over the next few years. The conversion from busy metropolitan airport to suburbia has involved a number of different construction companies. The overall responsibility for development rests with the firm Forest City Stapleton. With this much construction taking place, there is a lot of soil on residential lots that has to be kept onsite. Jaime Hernandez, project manager for Down to Earth Compliance of Aurora, CO, says that about three-fourths of the develop-ment has been done. “The demand for housing is skyrocketing here, and the more homes they build, the more work for us,” he notes. Employees of Down to Earth Compliance are respon-sible for erosion control on the lots where homes are being constructed by many different builders. To keep sediment on these lots while construction is taking place, they rely on ero-sion control wattles made by Gator Guard of Boise, ID, and supplied by Bowman Construction Supply of Denver. Hernandez says that he is convinced of the value of using Gator Guard, even if it costs more than some other products. With Gator Guard, “you can tell the difference when you jump on it or step on it. You can understand how it will last.” He explains that similar products made by other 20 EROSION CONTROL WWW.EROSIONCONTROL.COM D2 LAND AND WATER RESOURCE E very type of construc-tion project—building, road, bridge—involves erosion control. As soon as removal of an existing structure starts or a shovel turns over grass to expose the soil beneath, the need for erosion control begins.
