该项目是丹佛市历史上的第四个设计建设项目，也是丹佛运输和基础设施办公室（DOTI）选择SEMA作为设计建造承包商的第三个设计建设项目。该项目的雨水排水和公园设施的组合元素需要在公共安全和城市维护团队的需求方面进行特别的设计关注。除了安装大量排水和道路改进外，该项目还包括最先进的社区设施和丹佛的第一个共享街头概念。

The project created a greenway along 39th Avenue that collects and conveys floodwater through an open channel to the outfall at Globeville Landing Park. Crews installed extensive drainage and roadway improvements along with innovative features that included children’s play zones and a plaza, classrooms, community gardens, shade structures and bouldering elements.

In addition, the work included design and construction of a detention basin within the Park Hill Golf Course, connected by a storm-drainage system from the Holly Pond. That included utility relocations, jacking of pipes under the Regional Transportation District and Union Pacific Railroad tracks, landscaping, drainage system infrastructure improvements and water-quality enhancements.

该项目最大的挑战围绕着其中央愿景的重大变化，该愿景发生在实用程序和排水任务开始后12个月后发生。

After submission of documents for the 90% design stage, the design-build team and DOTI decided that part of the plan for Franklin to Williams streets needed to change. During a three-month pause, the entire project team worked to incorporate changes to the retaining walls and layout of the greenway without delaying the overall project completion date.

Without the use of design-build, such a sweeping change to the overall vision would not have been possible during construction of one of Denver’s most complex drainage projects.
