Land Located in a Designated Floodplain: Land located in the
floodway of a 100 year flood frequency as defined by Title 76, Chapter
5, M.C.A., or land deemed subject to flooding as delineated by the
most current floodplain maps available and adopted by the City of
Kalispell, shall not be subdivided for building or residential purposes,
or proposed for other uses that may increase the danger to life, health
or property caused by flooding.
(Ord. 1707, 12-19-2011)
Land located in wetlands, ponds or sloughs shall not be subdivided
for building or residential purposes or other uses that may increase
or aggravate hazards to life, health or welfare, or that may be prohibited
by state regulations unless these issues are mitigated.
A. Wetlands
Defined:
1. Wetlands
are areas inundated or saturated by surface or groundwater at a frequency
and duration sufficient to support, and that under normal circumstances
do support, a prevalence of vegetation typically adapted for life
in saturated or hydric soil condition based on the following:
a. The duration the area is inundated or saturated by surface or ground
water and under normal circumstances support a prevalence of vegetation
typically adapted for life in saturated or hydric soil condition;
and/or
b. If vegetation is absent, soils or hydrology that indicate wetland
areas.
2. This
definition does not include man-made wetlands and drainage facilities.
B. Setback:
1. A
minimum 100 foot setback shall be provided around the entire wetland
or that portion which is located on the property to be subdivided.
2. Proposed
lot boundaries will be located at or beyond the 100 foot setback.
(Ord. 1707, 12-19-2011)
Where a development is crossed by or is adjacent to a watercourse,
the developer shall mitigate the impacts of the development on the
watercourse through the use of setbacks and limitations on adjacent
development. This mitigation may be increased in areas of significant
floodplain, adjacent wetlands or for bank stabilization. Proposed
lot boundaries will be located at or beyond the minimum setback.
A. Purpose:
1. Supporting
the riparian habitat.
3. Protecting
the stream/river channel and banks.
4. Maintaining
an effective sediment filter which helps maintain water quality.
5. Protect
adjacent property from natural water course morphology.
B. Minimum
Setbacks:
1. A
minimum 200 foot setback shall be provided for "impaired streams"
(currently Ashley Creek and the Whitefish, Stillwater and Flathead
Rivers).
2. A
minimum 100 foot setback shall be provided for Spring Creek and Trumbull
Creeks.
3. A
minimum 50 foot setback shall be provided for all other water courses
such as intermittent or ephemeral streams. The USGS seven and one-half
(7 1/2) minute quadrangle map shall be used as a reference followed
by an on-site inspection by Planning Department staff to assist in
determining if setbacks are warranted. The water course must have
a defined bed or channel and associated riparian vegetation to be
considered for the minimum setback. A swale does not constitute an
intermittent or ephemeral stream.
C. Setback
Measurements: All watercourse setbacks shall be measured from the
ordinary high water mark. When no ordinary high water mark is discernible,
setbacks shall be measured from the top of the stream bank.
D. Permitted
Uses Within the Setback:
1. On-site
stormwater treatment facilities as approved by the Public Works Department.
2. Trails
and trail-related improvements (benches, trail signage, bridges and
other crossings) subject to the following provisions:
a. Improvements must be constructed to minimize bank instability, sedimentation,
nutrient and pollution runoff;
b. Trails shall be aligned to minimize damage to plant and wildlife
habitat; and
c. Trails crossing water courses must receive appropriate local, State
and Federal permits.
3. Streets,
sidewalks, utility lines or similar public construction for the purpose
of crossing a water-course subject to the following provisions:
a. Crossings shall be minimized to the greatest extent feasible;
b. Crossings with direct angles (90 degrees) shall be used to the greatest
extent feasible instead of oblique crossing angles;
c. Construction shall be capable of withstanding 100 year flood events;
d. A bank stabilization plan shall be prepared and approved by the City
prior to site preparation and installation of the improvement(s);
e. Streets shall allow passage of vehicular traffic per the current
Kalispell Standards for Design and Construction.
4. Control
of noxious weeds and activities required within limits outlined in
an approved noxious weed control plan.
5. Park
lands, park play facilities, open space and associated recreational
facilities.
6. Agricultural
fences, irrigation facilities and other agrelated activities.
E. Prohibited
Uses Within the Setback:
3. Streets
except for water course crossings.
4. Residential,
commercial or industrial primary and accessory structures.
F. The developer may request a reduction in the setbacks listed in subsection
B by providing the Planning Department with sound scientific information and reasonable mitigation to address potential impacts. In the case of bank stabilization a geotechnical report shall be required. The review and approval, conditional approval or denial of the requested reduction shall be in accordance with Section
28.07.01 (Variances) of these regulations.
(Ord. 1707, 12-19-2011)
For any subdivision that exceeds five acres in gross area, the
transfer of water rights shall be addressed at the time of preliminary
plat as provided in 76-3-504(1(j)) M.C.A.
A. The
following options will be considered:
1. Where
a homeowners association or other private or commercial entity is
proposed as part of the subdivision that will be charged with maintaining
open space, park lands, a golf course, agricultural pursuits or similar
uses that will require non-potable water for irrigation, and the use
of water for a closed loop thermal heat pump, existing water rights
may be transferred from the developer, as directed by the City Council,
to that entity commensurate with the proposed need.
2. The
City Council may request that water rights be transferred to the City
based on the City's need to provide municipal service to the
area.
3. The
water right may be severed from the land and extinguished.
B. If water
rights associated with the proposed subdivision are to be transferred
from the developer, they shall be transferred to the respective entities
at the time of filing a final plat. For phased projects the water
rights associated with each phase shall be transferred at the time
of filing of the particular final plat.
(Ord. 1707, 12-19-2011)
