Identifying Deficiencies and Recommending New Projects
Civiltech provided engineering services to update the City of Highland Park’s Storm Sewer Master Plan. The City’s previous plan had been completed in 2008. Civiltech’s update addresses the entire storm sewer system including projects completed since 2008. The plan identifies current storm system deficiencies and provides recommendations for new projects to address flooding.
An EPA SWMM hydrologic/hydraulic model was created to analyze the existing system, develop recommendations, and determine the impacts of the proposed improvements. The model was based on data available from the City utility atlases and GIS data and used Bulletin 70 rainfall data. The existing condition model analysis included the City’s main storm sewer system for each of the three major watersheds; Lake Michigan, Skokie River, and Middle Fork North Branch of the Chicago River.
Demonstrating Benefits of Proposed Improvements
The model replicated the existing flooding conditions that have been documented within the City and provided detail in areas that have been more prone to flooding. The proposed conditions model included and analyzed the existing system with the proposed improvements in place and demonstrated the benefits and level of protection that the proposed improvements provide.
