Wakefield Town Hall

Slide show prepared by:

Metropolitan Area Planning Council

How is Stormwater Regulated?

  • Directly Regulated

  • MA Wetlands Protection Act, Stormwater Management Standards (Conservation Commission)

  • Indirectly Regulated

  • Zoning bylaw

  • Subdivision rules and regulations

  • Site plan guidelines

  • Board of Health Regulations


Stormwater/LID Regulation

New Approaches to Direct Regulation

  • Stormwater bylaws

  • Illicit discharge bylaw

  • Clearing and grading bylaw

  • Erosion control bylaw


Stormwater/LID Regulation

Stormwater Bylaws—The Basics

  • Establishes new Stormwater Authority

  • Establishes thresholds and submittal requirements

  • Establishes performance standards

  • Outlines review process

  • Establishes fines for noncompliance

  • Requires operations & maintenance plan


Stormwater/LID Regulation

Stormwater Bylaws—Optional

  • Credits for use of LID techniques

  • General permit for certain activities

  • Engineering review fees

  • Required surety bond

  • Stormwater enterprise fund, stormwater utility, or stormwater fees

  • Address illicit discharges, construction disturbance


Stormwater Regulation

  • Performance Standards

    • Volume and rate controls

    • Recharge requirements

    • Treatment requirements

    • Illicit discharges prohibited

    • Erosion control requirements

    • Site design and landscaping standards

    • Redevelopment standards


Stormwater Regulation

Approaches to Stormwater/Erosion Control

  • Model Bylaws:

    • MA Smart Growth Tool Kit

    • Comprehensive Environmental Inc.

  • Topsfield: Stormwater and Erosion Control

  • Cohasset: Erosion Control and Stormwater

  • Salem: Stormwater

  • Framingham: Erosion Control


MA Smart Growth Toolkit

  • Authority:

  • Planning Board or Conservation Commission

  • Threshold:

  • Disturbance of 5000 ft 2 or greater

  • Performance Standards:

  • MA Stormwater Policy

  • Other:

  • General permit for small projects; allows multiple board stormwater review


CEI Model

Authority:

  • Separate Stormwater Authority

    Threshold:

  • Disturbance greater than 40,000 ft2 or disturbance of 200 ft2 on areas with slopes greater than 15%

    Performance Standards:

  • Uses MA Stormwater Policy or locally created Design and Landscape Standards

    Other:

  • No SW permit until ConsComm and PB issue permitting decisions


Topsfield Stormwater & Erosion Control

  • Authority:

  • Planning Board, but ConsComm reviews and conditions all wetland resource areas under Order of Conditions prior to SW Permit being issued by the Planning Board

  • Threshold:

  • Any alteration over 7500 Ft2 or over 4000 Ft2 on slopes more than 15 % with exemptions

  • Performance Standards:

  • MA Stormwater Standards


Cohasset Draft

  • Authority:

  • New Stormwater Commission

  • Threshold:

  • All development, any increase in stormwater or impervious surface: no area threshold

  • Performance Standards:

  • MA Standards and local guidelines (TBD)

  • Other:

  • Simplified permit process for 1- or 2-family homes

  • Also prohibits illicit discharges


Salem: Urban Model

  • Authority:

  • City Engineer is reviewing authority

  • Threshold:

  • All development, Minor Impact Permit for small projects

  • Performance Standards:

  • MA Standards and local guidelines

  • Other:

  • Accompanied by detailed guidebook, checklist, and submittal requirement list.


Framingham: Erosion Control

  • Authority:

  • Planning Board (requires Special Permit for nonexempt activities)

  • Threshold:

  • Threshold: Land disturbance of at least 4000 ft 2 on slopes steeper than 15%

  • Performance Standards:

  • MA Standards and local guidelines

  • Other:

  • Erosion control only


Review of Local Codes

Do They Prohibit LID?

Do they Promote LID?

Do they Agree with Each Other?

  • Zoning Bylaw and Site Plan Review

  • Subdivision Rules and Regulations

  • Board of Health Regulations

  • Wetland Regulations

  • Building Codes
