THE RIPARIAN BUFFER ZONE AND FLOODPLAIN SECTIONS OF THE PROPOSED ZONING
ORDINANCE: Questions and Answers
Q. If my property already contains a structure or is used within
the buffer zone or floodplain, how does the amendment affect me?
A. Existing uses are not affected, UNLESS you expand the existing
use or structure by more than 10% of the existing ground coverage.
Q. What if I want to improve my property that falls within the buffer
zone or floodplain area?
A. For land disturbing activities within these areas you will
need to apply for a permit. There are many uses that are NOT
considered land disturbances:
-
ordinary maintenance and landscaping;
-
individual home gardens;
-
repairs, additions and minor modifications to existing single family homes;
-
cutting firewood for personal use.
Q. How wide are the buffer zones being proposed?
A. 100 feet along large rivers, and either (Option A) 50 feet,
(Option B) 75 feet or (Option C) 25 feet along perennial streams and lakes.
The Athens Grow Green Coalition is urging the adoption of Option B,
75 feet.
Q. Are all uses of property within floodplains prohibited?
A. Not at all! The prohibited uses are:
-
Hazardous waste handling.
-
Hazardous and solid waste landfills.
-
New structures that require grading or a building permit.
(The ordinance includes requirements for balancing cuts and fills in the
floodplain.)
Many uses are allowed:
-
Excavation and fill to plant new trees or vegetation.
-
Restoration or enhancement of environmental areas consistent with
state and federal standards and guidelines.
-
Placement of structures that don't require a grading or building permit.
-
Routine repair and maintenance of existing uses and structures.
-
Emergency action of A-CC to mitigate a hazard and measures to remove
nuisances or other violations of law.
-
Ordinary maintenance and landscaping of existing disturbed areas,
home gardens, repairs, additions of 10% or less of existing lot coverage,
minor modification of existing single family dwellings, cutting of firewood
for personal use so long as canopy cover isn't reduced.
-
Natural water quality treatment or purification.
-
New public or private transportation or utility stream crossings
and water and sewer lines that run parallel to stream (with some safeguards
specified).
-
Walkways and bike paths constructed of porous materials whenever
feasible.
-
New stormwater pretreatment facilities provided they can't feasibly
be located elsewhere.
-
Timber production and forestry so long as a 70% tree canopy is maintained,
no trees are removed within 25 feet of stream bank, forestry activity is
consistent with Best Management Practices, and forestry activity
doesn't impair water quality pursuant to the Clean Water Act.
-
Agricultural production and management so long as it is consistent with
Best Management Practices, doesn't impair water quality, and is consistent
with all state and federal laws and regulations.
-
Existing land uses except when that land use is enlarged, is moved
to another portion of the property, or ceases for a period of more than
one year.
Q. Are all uses within Riparian Buffer zones prohibited?
A. No, the following uses ARE permitted:
-
Enhancement and restoration projects designed to improve water quality
or provide other environmental benefits so long as they are consistent
w/ state and federal standards.
-
Placement of structures that don't require a grading or building permit.
-
Repair, maintenance, and replacement of existing structures that
don't increase the existing structural footprint in the riparian buffer.
The disturbed portion of the buffer must be restored and non?native vegetation
replaced with native plants.
-
Construction of new structures that cover no more than 10% of the
buffer on a lot or parcel but which are no closer than 25 feet from the
bank.
-
Construction of one single-family home located on a tract of at
least 2 acres in size w/ no other dwelling on the tract.
-
Structures which can't by their nature be located outside the buffer
such as boat ramps or canoe launches, provided they meet all requirements
of the Erosion and Sedimentation Control Act, protect the integrity
of the buffer area as well as reasonably possible, and do not impair
drinking water.
-
Emergency action of A-CC to mitigate a hazard and measures
to remove nuisances or other violations of law.
-
Natural water quality treatment or purification.
-
New public or private transportation or utility stream crossings
and water and sewer lines that run parallel to stream (with some
safeguards specified).
-
Walkways and bike paths constructed of porous materials whenever
feasible.
-
New stormwater pretreatment facilities provided they can't feasibly
be located elsewhere.
-
Timber production and forestry so long as a 70% tree canopy is maintained,
no trees are removed within 25 feet of stream bank, forestry activity is
consistent with Best Management Practices, and forestry activity
doesn't impair water quality pursuant to the Clean Water Act.
-
Agricultural production and management so long as it is consistent with
Best Management Practices, doesn't impair water quality, and
is consistent with all state and federal laws and regulations.
-
Existing land uses except when that land use is enlarged, is moved
to another portion of the property, or ceases for a period
of more than one year.
-
Wildlife and fisheries management activities.
Q. Will this resolution affect how I can subdivide property that
includes buffer zone or floodplain?
A. Yes. All lots modified by lot line adjustments, or
new lots created from existing lots which contain buffer zone or floodplain
areas, must contain a buildable area large enough to accommodate the
uses permitted in the underlying zone. This means that some lots
that are larger than the minimum size required in the zoning ordinance
may not be allowed to be further divided.
Q. What if so much of my lot is within the buffer zone that I can’t
build as many structures as I had planned?
A. Density may be transferred out of unbuildable areas to buildable
areas of a lot, so long as a covenant is recorded which limits Land Disturbing
Activity or construction on the area from which density is transferred.
The density within the buildable area may not exceed twice the permitted
density allowed by the underlying zone.
Q. Can any variances be granted?
A. Yes:
-
The Board of Adjustments may grant a variance, subject to conditions and
a mitigation plan, where the buffer zone requirements represent an extreme
hardship for the landowner such that little or no reasonable economic use
of the land is available without a variance.
-
Also, Planning staff may permit a minor variance, a reduction in buffer
width over a portion of a property in exchange for an increase in buffer
width elsewhere on the same property, such that the average buffer width
is that specified by law (25, 50, or 75 feet depending on how the commission
votes). In no case can a minor variance decrease buffer width more than
25 feet.
