High Water Vulnerability

ARE YOU READY?

... for Lake Michigan and Huron to rise another foot this year?  Rising water levels in the Great Lakes also produce rising water levels in rivers and groundwater.

  • How will your infrastructure perform?

  • Will your wastewater treatment system outlet be restricted by high water?

  • Will your sewer pump stations be able to keep up with groundwater infiltration and inflow?

  • Will any water supply systems be threatened?

  • Will road flooding occur due to poor drainage conditions?

Gosling Czubak has the tools, resources, and know-how to help you evaluate vulnerabilities and develop action plans. EGLE has issued a request to all municipalities and industrial facilities to perform a vulnerability assessment of their infrastructure. 

A Vulnerability Analysis could include:

  • Identify assets that are impacted by high water levels

    • Wastewater treatment plant discharges

    • Stormwater basins

    • Wastewater pump stations

    • Flow increases due to elevated infiltration and inflow

    • Septic System Drainfields

  • Determine your ability to continue to meet NPDES discharge permit requirements

  • Define the 25 year and 100 year flood elevation near your assets

    • All systems should be operational and accessible at the 25 year flood elevation

    • All systems must be protected from damage by the 100 year flood elevation

  • Identify the potential for by-pass flows, backups, and spills

  • Prepare a mitigation and response plan for vulnerable assets

EGLE has provided a letter regarding High Water Level Impacts and General Guidance for Vulnerability Analysis.
