Sure, we miss having the airport close to the city -- but at least Denver got something out of the deal. Last year, the Stapleton redevelopment project received the James C. Howland Urban Enrichment Silver Award from the National League of Cities for its contributions to the urban environment. The old airport is being redeveloped into a combination of housing, shops, office buildings and parks, incorporating such elements of traditional neighborhood design as tree-lined streets, parks, front porches and old-time architecture, with 21st-century technology and sensibilities (including drought-resistant landscaping). And 21st-century capitalism: There was never a Wal-Mart on Main Street.
