Lake Front Landscaping Practices
Rain Gardens or Buffer Zones: It's all about stormwater runoff.
 |
Stormwater
Runoff
comes from rain falling
on lawns, patios and driveways or from rooftops (especially gutter
downspouts) and storm drains. Once the water flow or volume exceeds
the absorption ability of the surrounding vegetation, it can
drain directly into the lake. This runoff water often carries
bird or animal feces, insecticides, fertilizers and other pollutants
which may enter the lake without any type of filtration. |

The
Solution is simple............... add a Buffer Zone or Rain
Garden to absorb rain water flow and runoff.
Lakefront
buffer zones are areas of vegetation created near the lake shore
to trap sediments, excess nutrients and other pollutants. They
also serve to prevent erosion and help stabilize sloped areas of
the shoreline. They can be simple and natural or complex and well
manicured depending on the taste of the homeowner. The idea is
to at least have some kind of vegetation (beside green grass) along
the lakefront area - particularly where a slope invites stormwater
runoff into the lake. There are many buffer publications available
on the web to assist in creating a buffer zone and choosing
suitable plants. Native plants are always preferred as they are
easily adaptable to the environment, requiring little to no fertilizer
and also provide food and habitat to the native animals.

Creating
a Rain
Garden provides a natural
way to contain water runoff. Do you have an area in your yard that
turns into a raging river or a sloppy puddle every time it rains?
Not only does this racing water often erode soil and
create havoc in ones yard, it often causes large amounts of stormwater
runoff to directly or indirectly enter the lake. Usually carrying
with it large amounts of sediments, fertilizers or other pollutants
- all bad for our lake.
Building a rain garden
simply requires creating a depression in the ground along the
path of the water flow that is designed to collect, hold and slowly
allow water to re-enter the surrounding ground. This process actually
filters the water as it enters the ground water system. The area
is typically planted with a variety of plants (preferably native)
that mother nature has specifically designed to handle periods
of intense moisture alternated with dry spells. The roots of these
plants hold the surrounding soil securely in place while the plants
themselves offer not only aesthetic appeal but also a habitat to
native birds and animals.
