As the owner of shorefront property, you must examine your property and determine what erosion forces are at work. They will be different depending on whether you have property that is exposed or sheltered, high bank or low bank, etc.

The process of shoreline erosion may be due to natural causes such as the interaction of tidal action with the bank face. The erosion may be accelerated by activities such as boat wakes or high waves during storms. Each year, this erosion causes the loss of valuable shorefront property. In addition, bank erosion can adversely affect the living resources of our bays and waterways by increasing sedimentation and turbidity which decreases the light penetration needed to sustain critical underwater vegetation and other habitat.

The practices outlined in this brochure are basic and are presented to introduce you to the concepts. You may wish to seek professional guidance in the actual design of an erosion control project.

Why non-structural alternatives ?

The most commonly used techniques for erosion control have been the installation of physical structures such as bulkheads or rip-rap. Structures such as these may be necessary along very exposed (high energy) shorelines. Although bulkheads and rip-rap are effective in these areas, rip-rap or other non-vertical structures are preferable since they result in less disturbance and loss of adjacent shallow water habitats. In addition, bulkheads contain wood preservatives used to treat bulkheads which have been found to be toxic in the marine environment. Vertical walled bulkheads can cause increased erosion of adjacent, improved shoreline by reflection of wave energy. next.jpg - 5.1 K
