Mill Creek Watershed Study

Mill Creek Watershed Study

Location: Johnson County, Kan.

Client: Johnson County Stormwater Management Program

Completion Date: 2005

Burns & McDonnell prepared a comprehensive study of the Mill Creek Watershed and integrated the project data into an existing enterprise geographic information system (GIS) for the Stormwater Management Program of Johnson County, Kan. The study evaluates existing and anticipated future conditions within the watershed and develops a stormwater master plan and readily accessible data tools for future stormwater management facilities.

A relational database was created to house the stormwater data. The database was developed using SQL Server and ArcInfo with Spatial Database Engine. Stormwater conveyance systems and sub watersheds of 160 acres are being delineated using Arc/Info and ArcView Spatial Analyst. Using an automated process, runoff curve numbers are being developed from land use and soil types. In addition to curve numbers, HEC-RAS model runs will also be incorporated in this manner. Burns & McDonnell is facilitating the flow and quality of information between project team members via a project Web site. During the project, Burns & McDonnell may migrate the GIS data into the Arc8 platform.

Upon completion of the project, Johnson County possessed a database compatible with its enterprise GIS and capable of being implemented for all aspects of the stormwater management program.
