(1)
Wetlands.
(a)
Delineation. The applicant shall delineate the limits of wetlands
on the site in accordance with the following:
[1]
A full wetland delineation report conducted by a qualified wetland
biologist, soil scientist, or environmental professional of demonstrated
qualifications shall be submitted to the City. If there is a question

wetlands are present or not present on the site and a full delineation,
area measurement (in square feet), and description of any wetlands
determined to be present.
(b)
Resource protection standards.
[1]
Any applicant proposing a use, activity or improvement which
would entail the regrading or placement of fill in wetlands shall
provide the City with proof that the Pennsylvania Department of Environmental
Protection (Bureau of Dams and Waterway Safety and Bureau of Water
Quality Management) and the U.S. Army Corps of Engineers have been
contacted to determine the applicability of state and federal wetland
regulations. The applicant shall concurrently provide to the City
a copy of the application and any other wetlands information submitted
to the Department of Environmental Protection and the U.S. Army Corps
of Engineers.
[2]
Wetlands shall not be regraded, filled, piped, diverted, channeled,
built upon, or otherwise altered or disturbed except where state or
federal permits have been obtained.
[3]
Existing wetlands shall not be used for stormwater management
except where the wetlands are highly degraded and a mitigation program
is provided.
(2)
Wetland buffer.
(a)
Except as noted below, no more than 20% of a wetland buffer
shall be regraded, filled, built upon, or otherwise altered or disturbed.
(b)
The following uses or activities shall be permitted in the wetland
buffer and shall not be counted towards the 20% disturbance allowance:
[1]
Regulated activities permitted by the commonwealth.
[2]
Provision for unpaved trail access.
[3]
Selective removal of hazardous or invasive alien vegetative
species.
[4]
Vegetation management in accordance with an approved landscape
plan.

A soil or stream conservation project approved by the Northampton
County Conservation District.
(3)
Riparian buffers.
(a)
Delineation. For purposes of this chapter, riparian buffers
shall be divided into two zones:
[1]
Zone 1: Inner Riparian Buffer. This zone begins at the top of
each stream bank of an identified watercourse and occupies a margin
of land with a minimum width of 35 feet measured horizontally on a
line perpendicular to the edge of the water at the top of the defined
bank, as reviewed and approved by the City Engineer. Where very steep
slopes (25% and over) are located within 35 feet of a watercourse,
Zone 1 shall extend the entire distance of this sloped area.
[2]
Zone 2: Outer Riparian Buffer. This zone begins at the outer
edge of Zone 1 and occupies a maximum width of 35 feet in addition
to Zone 1.
[a]
In cases where Zone 1 extends beyond 35 feet due
to the presence of very steep slopes, the width of Zone 2 shall be
adjusted so that the total riparian buffer width equals a total width
of 70 feet.
[b]
Where the entire width of the Zone 2 riparian buffer
is not wooded, the outer edge, up to the maximum seventy-foot width,
shall be maintained as a filter strip of dense grass or other features
to provide sediment filtering, nutrient uptake, and convert concentrated
flow to uniform, shallow sheet flow.
[3]
Measurements for the Zone 1 boundary are to be made horizontally,
perpendicular from the following reference points: edge of stream
bank of perennial streams, center line of intermittent streams, and
mean water level of lakes and ponds. Measurements for the Zone 2 boundary
are to be made horizontally, perpendicular from the boundary of the
environmentally sensitive lands (see Diagrams 5-1, 5-2).
Diagrams 5-1 and 5-2 Notice: Diagrams are for illustration purposes
and are not to be construed as the operative language of the Zoning
Ordinance. The obligations are governed only by the written standards
set forth in this chapter.

with erosion control.
[d]
Storage of any hazardous or noxious materials.
[e]
Use of fertilizers, pesticides, herbicides, and/or
chemicals in excess of prescribed industry standards.
A.
B.
Intent. The intent of this section is as follows:
(1)
To conserve and protect sloped land from inappropriate development,
such as excessive grading and extensive vegetation removal.
(2)
To avoid potential hazards to property and the disruption of ecological
balance which may be caused by increased surface water runoff, flooding,
soil erosion and sedimentation, blasting and ripping of rock, and
landslides.
(3)
To encourage the use of sloped land for conservation and other uses
which are compatible with the preservation of natural resources and
protection of the environment.
(4)
To avoid loss of biodiversity and wildlife habitat and corridors.
C.
Interpretation. Interpretation of steep slope areas:
(1)
In any application where the lot includes areas of steep, very steep
slopes and severely steep slopes, the applicant shall, using two-foot
contours, delineate slopes from 12% to 25%; greater than 25% but less
than 35%; and greater than or equal to 35%. The applicant shall use
an actual field topographic survey as the source of contour information
and the basis for depicting such slope categories.
(2)
This section shall apply only to those steep, very steep, and severely
steep slopes which exist for three consecutive two-foot contour intervals
(six cumulative vertical feet of slope). All steep, very steep, and
severely steep slope areas shall be shown for the purpose of City
review and verification, but only those occurring over three consecutive
two-foot contour intervals will invoke the standards of herein.
(3)
Once delineated, the mapping provided by the applicant shall be reviewed
by the City Engineer. The applicant shall be required to follow all
regulations of this section for those areas which reflect steep and
very steep slope conditions as determined in accordance with this
section through the City Engineer's review.
D.
Application procedures.
(1)
Before a permit is issued for any construction or land disturbance
on land within or affecting steep and very steep slope areas, the
following material shall be submitted for review by the City Engineer:
(a)
Plans drawn to a scale of at least one-inch equals 50 feet,
sealed by a registered professional engineer, depicting the following:
[1]
The location, dimensions and elevation of the property.
[2]
Existing and proposed uses and development.
[3]
An earthmoving plan of the property which indicates existing
and proposed grades with contour lines at two-foot intervals within
the area of any proposed activity, disturbance or construction. All
areas of steep and very steep slope shall be graphically highlighted.
[4]
A site plan indicating existing and proposed buildings, structures,
other impervious surfaces, storm drainage facilities and retaining
walls. The site plan shall also depict within areas of steep and very
steep slopes existing vegetation, including woodlands, open areas
and their ground cover type, as well as proposed landscaping material
to be installed.
[5]
Typical cross section and elevations of the property and proposed
buildings and structures at intervals prescribed by the City Engineer,
as well as architectural plans, building elevations, and site sections.
[6]
Photographs showing existing uses, vegetation and topography
within the steep and very steep slope areas.
[7]
A statement signed and sealed by a registered architect or professional
engineer explaining the building methods to be used in overcoming
foundation and other structural problems created by slope alteration;
the proposed techniques to preserve natural drainage and prevent soil
erosion and sedimentation; and the methods proposed to avoid excessive
surface water runoff to neighboring properties and/or streets.
[8]
Plan, profile and typical cross sections of any proposed street,
emergency access or driveway within areas of steep and very steep
slopes, with the seal of a registered professional engineer thereon.
E.
Standards and criteria for applications. In evaluating any application,
the City Planning Commission shall determine consistency of the proposal
with the following:
(1)
In areas with a natural slope of 12% to 25%, no more than 30% of
such areas shall be regraded, cleared, built upon or otherwise altered.
(2)
In areas with natural slope of 25% to 35%, no more than 15% of such
areas shall be altered, regraded, cleared, built upon or otherwise
altered.
(3)
Disturbances shall be minimized where the length or area of steep
and very steep slope is extensive both on the site and on adjacent
lands within 50 feet of the site.
(4)
In areas where the natural slope is 35% or greater, no area shall
be altered, regraded, cleared, built upon or otherwise altered. Exceptions
include approved trail development or repair.
(5)
The proposed development, any impervious cover and resultant disturbance
to the land and existing vegetative cover will not cause stormwater
runoff and/or related environmental problems off the site.
(6)
Removal of or disturbance to existing vegetation in steep slope areas
shall be minimized. The proposed impacts on existing vegetation shall
be evaluated in terms of the potentially detrimental effects on slope
stability, conveyance and recharge of stormwater, aesthetic characteristics
of the landscape and existing drainage patterns. Further, it shall
be demonstrated that any and all reasonable mitigation techniques
and procedures will be utilized or have been considered in the preparation
of the plan, such as revegetation measures, control of soil erosion
and sedimentation, stormwater management, and the like. For purposes
of such demonstration, the City may request additional information,
including, but not limited to, an erosion and sedimentation plan.
(7)
Important visual qualities of the site shall be retained to the maximum
extent possible. In addition to vegetation, these may include hilltops/ridgelines,
rock outcroppings, and the natural terrain and contours of the site.
(8)
Road and driveway construction shall follow the natural topography
to the maximum extent possible. Cuts, fills and grading shall be minimized.
(9)
Innovative, imaginative building techniques that are well-suited
to slope conditions shall be encouraged, consistent with other applicable
codes and regulations.
(10)
The stability of the slope, as characterized by the existing
interrelationships among the soil, vegetation, and rock, shall be
disturbed as little as possible.
(11)
Proposed buildings and structures shall be of sound engineering
design. Footings shall be designed in response to the site's slope,
soil and bedrock characteristics. Footings shall extend to stable
soil and/or bedrock.
(12)
All disturbed areas shall be stabilized and seeded or planted,
and notes to this effect shall appear on all plans.
(13)
Finished slopes of all permitted cut and fill shall not exceed
three to one or 33%, unless the applicant can demonstrate the method
by which steeper slopes can be stabilized and maintained adequately.
