There are many nature-based solutions that
link to the four Green Shores principles .
For example:
Preserving the integrity and connectivity of
shoreline processes could include a
Green Shores project with removal of a
seawall, re-sloping and addition of beach
nourishment and large woody materials .
This helps to restore and maintain shoreline
processes such as sediment movement .
Other nature-based options include marsh
or estuary restoration of the foreshore, and
using features that naturally attenuate wave
action and provide habitat .
Maintain and enhance shoreline habitat
diversity and function could include a
Green Shores design that preserves or
restores the riparian area through the use
of natural woody materials, stones, and
native plants that are well adapted to
conditions of the shore environment .
This type of vegetation provides food for
young aquatic species, helps with wave Figure 8.3 – Typical movement of water runoff to the shoreline via

Minimizing and reducing pollutants to the
shoreline environment can be achieved
by reducing the potential for any upland
contaminants that drain off a roof, driveway
or property as shown in the following
diagram, from reaching the shoreline
(Figure 8 .3) . Methods may include use of
permeable pavers, water collection systems
and development of rain gardens and
further details are provided below .
Reduce and reverse cumulative impacts to
shoreline systems is accomplished when
property owners and communities work
together to implement a ‘neighborhood
scale’ Green Shores project that links Riparian area is defined as the
together adjacent properties . This may be transitional zone between the upland

and more functionally effective for the
