B. Exemption requirements.
(1) An applicant proposing the cumulative installation of 1,000 square feet or less of impervious surface coverage since April 8, 2014, may be exempt from the design, plan submittal and processing requirements of Articles
III and
IV of this chapter. No person or activity is exempted from compliance with §
93-32 and Articles
VI,
VIII, and
IX of this chapter. Exemptions do not relieve the applicant of the responsibility to secure required permits or approvals for activities regulated by any other code, law, regulation, or ordinance. Exemption shall not relieve an applicant from implementing such measures as necessary to meet compliance with any NPDES permit requirements. Any exemption based on false, misleading, or erroneous information provided by an applicant is void without the necessity of any proceedings for revocation. Any work undertaken or use established pursuant to such permit or other authorization is unlawful.
(2) The determination of whether a project qualifies for an exemption
will be made by the Township Engineer at the time a building permit,
zoning permit, land development or other permit application is submitted
to the Township.
(3) Impervious area shall include all impervious and semi-impervious
areas as defined by this chapter.
(4) No impervious surface coverage shall be installed and no earth disturbance
activity shall be conducted within any existing drainage or stormwater
easement created by or shown on any recorded plan.
(5) Existing, unimproved lots of record in the Township shall not be
eligible to qualify for an exemption as specified under this chapter.
(6) The Township may recommend imposing additional conditions to the
approval of an exemption under this section where he or she feels
it is necessary to protect a down-gradient property owner, the public
health, safety or welfare of Township residents or where an existing
drainage problem is located in the vicinity of the proposed project.
For projects under this scenario, the Township Engineer shall forward
a report of the recommendations to the Township Board of Supervisors
who shall make the final decision in these situations.
(7) All cumulative new impervious areas will be tracked by the Township.
If a permit application is submitted that proposes new impervious
areas which exceed the maximum allowed for an exemption to be approved,
the applicant must provide stormwater management controls to address
the entire impervious area proposed within that application.
C. Small projects.
(1) Regulated activities that, measured on a cumulative basis from April
8, 2014, create additional impervious areas of more than 1,000 square
feet and less than 5,000 square feet, or involve earth disturbance
activity of an area less than 5,000 square feet and do not involve
the alteration of stormwater facilities or watercourses are considered
small projects and shall follow the process herein, provided the following
criteria are met:
(a)
Impervious area shall include all impervious and semi-impervious
areas as defined by this chapter.
(b)
No impervious surface coverage shall be installed and no earth
disturbance activity shall be conducted within any existing drainage
or stormwater easement created by or shown on any recorded plan.
(c)
Existing, unimproved lots of record in the Township shall not
be eligible to be considered a small project as specified under this
chapter.
(d)
The Township may recommend imposing additional conditions to
the approval of a small project application under this section where
he or she feels it is necessary to protect a downgradient property
owner, the public health, safety or welfare of Township residents
or where an existing drainage problem is located in the vicinity of
the proposed project. For projects under this scenario, the Township
Engineer shall forward a report of the recommendations to the Township
Board of Supervisors who shall make the final decision in these situations.
(e)
All cumulative new impervious areas will be tracked by the Township.
If a permit application is submitted that proposes new impervious
areas which exceed the maximum allowed for the project to be considered
a small project, the applicant must provide a SWM site plan compliant
with all requirements of this chapter.
(2) Anyone proposing a small project shall submit three copies of the
small project application to the Township.
(3) The small project application shall be submitted in a format that
is clear, concise, legible, neat and well organized and shall include:
(a)
Small project application form (Appendix A).
(b)
Small project sketch plan including the following:
[1]
Name and address of landowner (and/or developer).
[3]
Name of individual and/or firm that prepared the sketch if different
than landowner/developer.
[4]

(2) Any small project with a limit of disturbance in excess of 5,000
square feet shall be required to obtain a letter of adequacy from
the Lancaster County Conservation District as a condition of approval
of the small project application.
