Choosing The Right Stp Choosing The Right Stp Presentation Transcript

  • Selecting the Most Effective Stormwater Treatment Practice Presented by the Center for Watershed Protection
  • Seven-Step Process to STP Screening
    • Land Use
    • Physical Feasibility
    • Climate/ Regional Factors
    • Watershed Factors
    • Stormwater Management Capability
    • Pollutant Removal
    • Community and Environmental Factors
  • Customizing Matrices to Local Needs
    • Matrices are not necessarily exhaustive.
    • Specific additional criteria may be incorporated or removed depending on local goals.
    • Most of the material in the screening matrices provides technical guidance, and is not necessarily a regulatory mandate.
  • Step 1. Land Use
    • Rural —STPs for low density areas
    • Residential —STPs for med. to high density residential
    • Roads & Highways —STPs for major roads Commercial— STPs suitable for new commercial areas
    • Hotspot Land Uses— STPs for high risk areas
    • Ultra-Urban Sites— STPs for space-limited areas
    Step 1 Matrix
  • Step 2. Physical Feasibility
    • Soils
    • Water Table
    • Drainage Area
    • Slope
    • Head
    Step 2 Matrix
  • Step 3. Climate and Regional Factors
    • Arid/Semi-arid
    • Low Relief
    • Cold Climates
    • Karst Topography

    Step 3 Matrix
  • Step 4. Watershed Factors
    • Considerations for the following resource categories:
    • Sensitive Streams
    • Impacted Streams
    • Non-Supporting Streams
    • Restorable Streams
    • Aquifers
    • Urban Lakes
