Urban stormwater planning

Reduction of flooding brings significant benefits to neighborhoods, businesses and urban infrastructure. GKCC has brought state of the art tools to bear on this problem with great success.  For the T-REX project, GKCC took on the challenging design of Interstate 25 through Denver where chronic flooding routinely shut down the highway.  Modeling of the drainage basin was accomplished using detailed digital terrain models, GIS maps of land use, and full-dynamic analysis of the existing and proposed drainage systems.  This integrated approach enabled the development of very practical and cost effective solutions.

Our recent project experience is extensive and includes master planning for the T-REX Corridor for Colorado Department of Highways, the Broadway Basin for the City and County of Denver, Lena Gulch Major Drainageway Planning for City of Wheat Ridge and the Urban Drainage and Flood Control District.  We have accomplished stormwater planning studies for communities in Arizona, Nevada and Southern California and have worked with many different requirements for planning and design.

Our stormwater modeling capability includes XP-SWMM and EPA SWMM for full-dynamic unsteady flow analysis, and StormCAD and InRoads Storm and Sanitary for steady-flow analysis.  We have used many additional applications for the analysis of special problems in hydrologic modeling and urban hydrology.
