Shoreline Erosion Management Project

Shoreline Erosion Management Project

At the request of the Town Manager, John Eldridge, a working group was formed to help develop standards for shoreline stabilization in Brunswick.   The Town Planner serves as primary staff with assistance by the Harbor Master & Marine Resource Officer, and the Director of Planning and Development.

 

Logic Model: Shoreline Erosion Management

The following logic model depicts the planned work and intended results for the shoreline erosion management project based on these two (2) assumptions:

  1. Natural shoreline erosion is a community issue in Brunswick
  2. Additional information is required for local management decisions.

Logic Model

 

Shoreline Stabilization and Living Shoreline Best Management Practices (BMPs)

In Maine, the state and federal permit process for activities associated with shoreline stabilization favors construction practices that avoid and minimize direct impacts to wetlands and water bodies. The most expeditiously approved shoreline stabilization method that achieves the goal of reducing direct resource impacts is to fill angular blasted ledge or riprap stone on the seaward face of a cleared and graded upland slope. Angular stone is accepted for its ability to absorb wave action, and that it may be securely installed at a relatively steep slope thus reducing its footprint within the resource. Two (2) primary concerns with the practice of using rock or structural methods of shoreline stabilization (i.e. retaining walls, bulkheads, etc.) include the removal of vegetated buffers, and the interruption to the natural transfer of upland sediment to wetlands and water bodies.

Ecologically sensitive methods of shoreline stabilization may provide long term solutions for the management of severe storms, flooding, and erosion.  Living shoreline methods are intended to sustain geological and ecological systems by restoring or enhancing natural functions and values through shoreline stabilization. Unfortunately, no Best Management Practices (BMPs) for constructing living shorelines are accepted by the natural resource agencies that regulate or advise Maine. To address this fact, this technical working group is tasked with developing innovative options for the Brunswick Town Council to consider in their policy discussions pertaining to shoreline management.
