The following items shall be included in the SWM site plan:
A. Appropriate sections from the municipality's Subdivision and
Land Development Ordinance, and other applicable local ordinances, shall be followed
in preparing the SWM site plans. In instances where the municipality
lacks subdivision and land development regulations, the content of
SWM site plans shall follow the county's Subdivision and Land
Development Ordinance.
B. The county shall not approve any SWM site plan that is deficient
in meeting the requirements of this chapter. At its sole discretion
and in accordance with this article, when a SWM site plan is found
to be deficient, the municipality may either disapprove the submission
and require a resubmission, or, in the case of minor deficiencies,
the municipality may accept submission of modifications.
C. Provisions for permanent access or maintenance easements for all physical SWM BMPs, such as ponds and infiltration structures, as necessary to implement the operation and maintenance (O&M) plan discussed in Subsection
E(9) below.
D. An approval signature block should be placed on the SWM site plan
to be executed upon approval of a subdivision or land development
plan, verifying that it is in compliance with the Luzerne County SWM
Plan.
E. The SWM site plan shall provide the following information:
(1) The overall stormwater management concept for the project.
(2) A determination of site conditions in accordance with the BMP Manual (NOTE: See §
444-32A). A detailed site evaluation shall be completed for projects proposed in areas of carbonate geology or karst topography, mined areas, and other environmentally sensitive areas, such as brownfields. Depending on site conditions, more stringent standards than those in this chapter may be imposed at the discretion of the Municipal Engineer.
(3) Stormwater runoff design computations and documentation as specified in this chapter, or as otherwise necessary to demonstrate that the maximum practicable measures have been taken to meet the requirements of this chapter, including the recommendations and general requirements in §
444-10; computations are required for all proposed stormwater management facilities.
(4) Expected project time schedule.
(5) A soil erosion and sediment control plan, where applicable, as prepared for and submitted to the approval authority, and in conformance with 25 Pa. Code Chapter
102.
(6) The effect of the project (in terms of runoff volumes, water quality,
and peak flows) on surrounding properties and aquatic features and
on any existing stormwater conveyance system that may be affected
by the project.
(7) Plan and profile drawings of all SWM BMPs, including drainage structures,
pipes, open channels, and swales.
(8) SWM site plan shall show the locations of existing and proposed on-lot
wastewater facilities and water supply wells.
(9) The SWM site plan shall include an O&M plan for all existing

shall address long-term ownership and responsibilities for O&M
as well as schedules and costs for O&M activities.

The SWM site plan shall include the following additional elements:
(a)
Construction details of all proposed stormwater management facilities.
(b)
A stormwater facility design narrative.
(c)
A signature block containing the name, address, and phone number
of the individual responsible for the operation and maintenance plan.
(d)
A drainage area map with time of concentration paths shown.
(e)
Existing contour intervals of two feet.
(f)
All existing features on the property and within 50 feet of
property.
(g)
Floodplain and floodway limits.
(h)
Proposed structures and proposed grades.
(i)
Soil boundary lines and descriptions.
(j)
Date of submission, north arrow, graphic scale, call before
you dig note and reference number, location map, name of development,
name and address of property owner, and individual preparing the SWM
site plan.
(k)
Existing and proposed easements.
(l)
Statement signed by landowner stating that they cannot alter
any stormwater management facility without prior permission of the
municipality.
A modification to a submitted SWM site plan that involves a
change in SWM BMPs or techniques, or that involves the relocation
or redesign of SWM BMPs, or that is necessary because soil or other
conditions are not as stated on the SWM site plan as determined by
the municipality, shall require a resubmission of the modified SWM
site plan in accordance with this article.
A disapproved SWM site plan may be resubmitted, with the revisions
addressing the municipality's concerns, to the municipality in
accordance with this article. The applicable review fee must accompany
a resubmission of a disapproved SWM site plan.
The municipality's approval of an SWM site plan authorizes the regulated activities contained in the SWM site plan for a maximum term of validity of five years following the date of approval. The municipality may specify a term of validity shorter than five years in the approval for any specific SWM site plan. Terms of validity shall commence on the date the municipality signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to §
444-20 within the term of validity, then the municipality may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the municipality shall be resubmitted in accordance with §
444-18 of this chapter.
