This chapter shall be known as and may be cited to as the "Easttown
Township Natural Resource Protection Ordinance."
A.
These regulations are intended to protect the rights of the residents
of Easttown Township to enjoy clean air, pure water and the natural,
scenic, historic and aesthetic values of the environment through the
preservation of woodlands, wetlands, aquifers and floodplains, as
set forth in the Pennsylvania Constitution and in other commonwealth
and federal statutes. In particular, it is the Township's purpose,
through this chapter, to conserve the following natural resources:
(1)
Natural resources identified as land or water resource areas, e.g.,
groundwater recharge zones (aquifers), springs, streams, wetlands,
woodlands, prime wildlife habitats and areas constituting high recreational
and other amenity value which exist on developed or undeveloped land.
(2)
Natural resources performing beneficial ambient air quality or microclimate
functions, e.g., by abating glare and noise, entrapping dust and other
particulates and contributing to the reduction of climate stress and
energy costs.
B.
To accomplish this, the ensuing standards are intended to:
(1)
Define and delineate selected natural resources within the Township
and establish resource protection standards to mitigate potential
hazards associated with land use activity.
(2)
Protect natural resources within the Township in accordance with the goals and objectives of the Easttown Township Comprehensive Plan, the Easttown Open Space, Recreation and Environmental Resources Plan, and the applicable provisions of Article VI of the Pennsylvania Municipalities Planning Code, Act 247.[1]

Editor's Note: See 53 P.S. § 10101 et seq.
C.
No such provision of these regulations shall be construed to deny the right of any property owner to use his/her land as may be permitted by the Township's land use codes. Rather, it is the purpose of these regulations to ensure that such uses minimize disturbances to natural resources and that reasonable measures are taken to mitigate any adverse impacts of such uses. Property owners may use their land as permitted in Chapter 455, Zoning, and Chapter 400, Subdivision and Land Development, provided that the regulations herein are also adhered to.
[Amended 6-2-2014 by Ord.
No. 422-14]
The natural resource protection standards set forth in this
chapter shall apply to all land development, site preparation and
site disturbance activities.
A.
All uses shall be developed in a manner consistent with the preservation
of the quality of the existing environment and of any natural amenities
present on the site. Such uses shall provide for the preservation
and proper management of natural drainage systems, minimizing of grading
and removal of scenic vegetation, preservation of woodlands and substantial
stands of trees and the preservation of scenic vistas, historic landscapes
and any other natural resources and features existing on the site.
B.
For the purposes of this chapter, the sections within this chapter
shall be overlays to the underlying districts as shown on the Easttown
Zoning Map,[1] and as such, the provision for each of these sections
shall serve as additional requirements to the underlying zoning district
provisions. In the event that a conflict exists between a section
of this chapter and the underlying district(s), the more restrictive
provision shall apply.
C.
Should the boundaries or delineations of any section of this chapter
be revised as a result of legislative or administrative actions or
judicial decision, the zoning requirements of the underlying zoning
district and other applicable sections of this chapter shall continue
to apply.
In the interpretation and application of this chapter, the provisions
hereof shall be held to be the minimum requirements for the promotion
of the public health, safety and general welfare. Where the provisions
of this chapter impose greater restrictions than those of any other
ordinance or regulation, the provisions of this chapter shall be controlling.
Where the provisions of any statute, other ordinance or regulation
impose greater restrictions than this chapter, the provisions of such
statute, ordinance or regulation shall be controlling.
Unless otherwise expressly stated, the following terms, words
and phrases shall be construed throughout this chapter to have the
meanings herein stated. Applicable regulations stated in conjunction
with these definitions shall be complied with. The singular shall
include the plural, and the plural shall include the singular. The
present or past tense shall include the future tense. The masculine
gender includes the feminine and neuter genders. The word "shall"
and must" are mandatory; the words "may" and "should" are permissive.
The words "used for" shall include "designed for."

management basins, to diminish and mitigate views of a development
from off site.
[Amended 12-15-2014 by Ord. No. 424-14]
A strip of required yard space adjacent to the boundary of a property or district, not less in width than is designated in Chapter 455, Zoning, which is landscaped for the full width and on which is placed a screen of sufficient density not to be seen through and of sufficient height to constitute an effective screen and give maximum protection and immediate visual screening to an abutting property or district. The required screen shall be permanently maintained and shall constitute a planting of dense evergreen trees or a compact evergreen hedge or, where specifically designated in this chapter, an appropriate wall, fence, suitable planting or combination thereof. All planting shall comply with the provisions of this chapter.
Plantings placed between incompatible land uses or zoning
districts to obscure views of the adjacent property or use.

swamps, marshes, bogs, and similar areas. Any area meeting the official
"wetland" definition of the United States Army Corps of Engineers,
the United States Environmental Protection Agency, or the Pennsylvania
Department of Environmental Protection shall be considered a wetland
for the purposes of this chapter. In the event the definition of a
"wetland" conflicts between any of these agencies, the more restrictive
definition shall apply.

and foraging or feeding conditions necessary to maintain population
of animals.
Any building lot having more than one viable tree, six inches
or greater in diameter dbh, per 1,500 square feet of gross lot area,

complete aerial canopy. For the purposes of this chapter, the extent
of any woodland shall be measured from the dripline of the outer trees.
Woodlands do not include orchards, commercial nurseries, Christmas
tree farms, or old fields, where more than 75% of the trees are smaller
than six inches dbh.
Any activity which alters the existing structure of a woodland
or hedgerow; disturbances include the cutting or removal of canopy
trees, subcanopy trees, understory shrubs and vines, woody and herbaceous
woodland floor species. "Woodland disturbance" also includes any activity
which constitutes a land disturbance (exposes soils, alters topography,
destroys habitat) within a woodland or hedgerow. "Woodland disturbance"
does not include the selective cutting of trees or removal of invasive
plant species.
