Burns  Watershed Planning And Regulation Burns Watershed Planning And Regulation Presentation Transcript

  • Streams, Watersheds and Land Use Regulation Community Development Department York, Maine
  • Streams, Watersheds and Land Use Regulation
    • Impervious Surfaces Policy
    • Impervious Science
    • Ecosystem-Based Management
    York Community Development Department
  • Impervious Surfaces
    • It all started innocently enough…
      • A proposal to overhaul the Zoning provisions dealing with impervious surfaces in October 2005
      • A new Natural Resources Chapter for the Comprehensive Plan in May 2006
      • A goal about protecting water quality in June 2006
    York Community Development Department
    • Why regulate impervious surfaces?
      • Main Reason:
        • impervious surfaces are a primary determinant of surface water quality
      • Secondary Reasons:
        • Relationship to storm water volumes and flooding
        • Relationship to retaining open spaces

  • York Community Development Department
    • Why change our requirements?
      • Inconsistent use of terms
      • Inconsistent application of standards
    York Community Development Department
    • Inconsistent Use of Terms:
      • “ lot coverage”
      • “ maximum coverage”
      • “ foundation coverage”
      • “ coverage”
      • “ impervious surface”
      • “ impervious surface ratio”
    York Community Development Department
    • Inconsistent Application of Standards:
      • In some zones, impervious surfaces are regulated the same way for every use
      • In some zones, impervious surfaces are not regulated at all for residential uses
      • In some zones, the calculation of impervious surface differs for residential and non-residential uses
      • In the Shoreland Overlay District, impervious surfaces are defined differently than in the base zones
    York Community Development Department
    • Conceptual proposal rejected…
      • No relationship between proposed standards and science
      • Directed by the Board of Selectmen to go back to the drawing board, and to return with a science-based approach
    York Community Development Department
  • Impervious Science
    • What does a scientific approach require?
    • We relied heavily on work by the Center for Watershed Protection
    • CWP.ORG
    • Our bible: Rapid Watershed Planning Handbook: A Comprehensive Guide for Managing Urbanizing Watersheds (2001)
    York Community Development Department
    • Impervious surfaces should be evaluated at the second order watershed level
    • Starting point is to generate a 2 nd order watershed map of York
      • Had recently obtained 2’ contour data
      • Needed to generate new stream layer based on contours
      • Needed to generate watersheds layer based on streams and contours
    York Community Development Department
    • Why the quad sheets don’t cut it any more…
    • York Beach Quadrangle:
      • Prepared in 1956
      • Photorevised in 1973 – 35 years ago
      • Scale of 1:24,000
      • 20’ contours
    • York’s GIS
      • Based on current (1998 -2005) aerial photography
      • 6” resolution
      • 2’ contours
    York Community Development Department
  • Quad or Local Mapping?
    • York Beach Quad Sample
    • York GIS Sample

    • As we proofed our initial work, we found some significant flaws
    • We have contracted with Tom Burns to take our streams and watersheds work to the next level
      • One big gap – missing the storm water system
      • Second problem – using GIS software to generate watersheds without understanding the implications of the program settings
    York Community Development Department
  • Ecosystem-Based Management
    • The State of Michigan defines this as: “a process that integrates biological, social and economic factors into a comprehensive strategy aimed at protecting and enhancing sustainability, diversity and productivity of our natural resources.”
