Alternatives to Seawalls
There
are many effective shoreline stabilization
alternatives to seawalls and these alternatives have many advantages, including
reduced cost and maintenance. Seawalls protect only the land immediately behind
them but offer no protection to adjacent areas. In fact, vertical faces may
reflect wave energy, causing increased erosion in front or to the sides of the
structure. A vertical wall effectively eliminates shallow shoreline areas
thereby eliminating functions such as wildlife habitat, stormwater treatment and
attenuation/absorbsion of erosion-causing wave energy.
Rip-rap, unconsolidated rock material, can also be placed along a shoreline or
in front of a seawall to break the force of waves, protect the shore from
erosion, and can offer some functionality of habitat since some vegetation is
able recruit within the rock voids.
A naturalized shoreline is
one that is designed to work with and not against the forces of nature and
should incorporate existing natural features, such as a gradual slope, native
vegetation, rocks, etc. You can design a naturalized shoreline to accommodate
boat docking, scenic access, fishing, and other appropriate human activities. A
naturalized shoreline can accommodate both proper usage and site
conservation.
If you choose to maintain or develop a naturalized shoreline, you may need only
to maintain those features that provide positive aesthetic and natural benefits,
such as wildlife habitat and stormwater management, in the design of your
proposed shoreline. In doing so, you will not only increase your enjoyment of
the property, but also enhance both its resale value and its value as a natural
system.
Careful plant selection is required when acquiring plants for shoreline
stabilization. Native plants with extensive root systems, adaptable to the rise
and fall of water, and not prone to freeze, are preferable. The agencies listed
below can assist you in designing shoreline vegetation projects, and local
"native plant" nurseries can help you select appropriate plant species and other
natural materials.
When considering
shoreline management options, property owners should consult marine contractors
or design engineers, professionals who are trained to design and experienced in
construction of shoreline structures. In addition, those agencies which require
permits for construction should also be consulted, regardless of the likely size
or cost of the project.
