All activities shall comply with the rules and regulations established
by the Northampton County Conservation District.
[Amended 7-1-2014 by Ord.
No. 2014-06]
A. Purposes. In addition to the floodplain management regulations of Chapter
150, Floodplain Management, there are areas of known alluvial soils lying outside the identified floodplain areas. The intent of this section is:
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. III)]
(1) To regulate development in areas of the Township in which alluvial
soils lying adjacent to streams are known to possess characteristics
indicative of flooding and/or chronic wetness which could pose hazards
to the public health, safety and welfare due to flooding and pollution
if indiscriminately developed.
(2) To reduce the financial burden imposed on the Township and individuals
by floods and overflows on lands.
(3) To permit certain uses which can be appropriately located in such
areas and which will not impede the flow of floodwaters or otherwise
cause danger to life and property at, above or below their locations
along the flooding.
(4) To provide sufficient drainage courses to carry abnormal flows of
stormwater in periods of heavy precipitation.
(5) To permit and encourage the retention of open land uses which will
be so located and designed as to constitute an appropriate part of
the physical development of the Township as provided for in the Comprehensive
Plan.
B. Alluvial soil floodplain areas.
(1) Areas designated as "alluvial soils" are based on the soil map prepared
by the Soil Conservation Service of the United States Department of
Agriculture, and published in the Soil Survey: Northampton County,
Pennsylvania. These areas contain one or more of the soil types which
are identified by the Soil Survey: Northampton County as "soils of
floodplains that are subject to overflow."
(2) The areas delineated as "alluvial soils" shall be used only to determine where the provisions of the approval procedure in the following subsection shall apply. It shall not be considered an exact delineation for the purposes of applying the regulations defined in §
300-37E.
C. Applicability. The provisions of this section shall be required for
all development plans and for all uses which lie within alluvial soils
areas, including, but not limited to uses requiring or involving buildings
and structures; facilities such as septic systems and wells which
will be located in or within a distance of 100 feet from areas designated
as containing alluvial soils; and recreational or utility uses within
or adjacent to alluvial soils.
D. Approval procedure. The Zoning Officer shall require submission of
a detailed alluvial soil delineation prepared by a qualified engineer,
soil scientist, hydrogeologist, or sewerage enforcement officer approved
by the Board of Supervisors in accordance with accepted soil delineation
practices.
E. Alluvial soil protection regulations. On any site or portion of a
site which is found, based upon a detailed investigate pursuant to
the provisions of this section, to contain potential hazards due to
flooding, chronic wetness or pollution, the use regulations of the
zoning district in which the site is located shall apply, except that
the following uses shall be prohibited:
(1) All permanent residential dwellings and permanent commercial or industrial
buildings or structures.
(2) The filling of marshlands, removal of topsoil, or damming or relocation
of any watercourse except with the approval of the Commonwealth of
Pennsylvania Department of Environmental Protection.
(3) Sanitary landfill, dump, junkyard, outdoor storage of vehicles and/or
materials, including manure.
(4) On-lot sewerage disposal systems.
No materials or wastes shall be deposited upon a lot in such
form or manner that they may be transported off by natural causes
or forces, nor shall any substance which can contaminate groundwater
or surface water or otherwise render groundwater or surface water
undesirable as a source of water supply or recreation, or which will
destroy aquatic life, be allowed to enter any groundwater or surface
water. Applicable Department of Environmental Protection regulations
shall apply.
Any proposed land use located in an area which has a year-round
or seasonal high-water table which comes to within four feet of a
ground surface and which may directly by means of effluent discharge
into the ground or indirectly through the leaching of stored materials
result in the pollution of the groundwater shall be prohibited from
developing in such areas. The determination of such hazards shall
be made by the appropriate state agency and/or by a qualified sanitary
engineer, geologist or soil scientist approved by the Board of Supervisors.
Bonding will be required for all proposed centralized water
supply systems in an amount equal to the replacement cost of such
facility in 20 years or at the end of the anticipated life span of
such system.
