| Abstract: |
Implementation of the Clean Water Act has significantly reduced point-source discharges t waters of the United States. Currently, the majority of pollution affecting surface waters attributed to remaining non-point sources. As a result, water resource specialists are becoming increaingly concerned with management of stormwater quality as well as quantity. A new baseball stadium complex in Denver, Colorado will demonstrate the integration of bioaugmentation techniques with constructed wetlands to simultaneously enhance environmental protection as well as stadium revenue.
In 1992, the City of Denver, Colorado was selected to be the home of a new major league baseball expansion team, the Colorado Rockies. The Denver Metropolitan MajorgueBaseball Stadium District was established and the process of locating and planning for a new stadium was initiated. A site was chosen in the highly urbanized downtown.
The extensive required for adequate visitor parking near the stadium eliminated much of the area available for the location of site storm drainage water quality elements. Both the stadium
district and the local urban drainage authorities expressed a strong commitment that quality of the new sports facility should not come at the expense of water quality in the South Platte River or other environmental concerns.
Proposed stormwater retention volumes were approximately 40% less than existing guidlelines.
In an effort to reduce lost revenue from eliminated parking areas, it was proposed that the physical settling capacity of proposed retention basins be enhanced with natural elements designed to ameliorate a wider range of urban pollutants. The stadium wash water and parking lot drainage system will integrate a number of traditional and mnovative best management practices with bio-remediation and passive constructed wetland technologies. The
intent is to create an ecologically compatible and economically feasible treatment system suitable for retrofit within the confined parameters of any traditional urban drainage system. |
