For any of the activities regulated by this chapter, the final
approval of subdivision and/or land development plans, the issuance
of any building or occupancy permit, or the commencement of any land
disturbance activity may not proceed until the property owner or developer
or his/her agent has received written approval of a stormwater management
site plan from the Borough.
All activities regulated by §
377-4 of this chapter and governed by the Jim Thorpe Borough Watershed Stormwater Management Plan shall prepare a stormwater management site plan. The stormwater management site plan shall consist of all applicable calculations, maps, and plans. A note on the maps shall refer to the associated computations and erosion and sedimentation control plan by title and date. The cover sheet of the stormwater-related computations and the erosion and sedimentation control plan shall refer to the associated maps by title and date. All stormwater management site plan materials shall be submitted to the Borough in a format that is clear, concise, legible, neat, and well organized; otherwise, the stormwater management site plan shall be disapproved and returned to the applicant. The following items shall be included in the stormwater management site plan:
A. General.
(1) General description of project.
(2) General description of any permanent stormwater management techniques,
including construction specifications of the materials to be used
for stormwater management facilities.
(3) Complete hydrologic, hydraulic, and structural computations for all
stormwater management facilities.
B. Map(s) of the project area shall be submitted on twenty-four-inch-by-thirty-six-inch
sheets and shall be prepared in a form that meets the requirements
for recording the offices of the Recorder of Deeds of Carbon County.
The contents of the maps(s) shall include, but not be limited to:
(1) The location of the project relative to highways, municipalities,
or other identifiable landmarks.
(2) Existing contours at intervals of two feet. In areas of steep slopes
(greater than 15%), five-foot contour intervals may be used.
(3) Existing streams, lakes, ponds, or other bodies of water within the
project area.
(4) Other physical features including flood hazard boundaries, sinkholes,
streams, existing drainage courses, areas of natural vegetation to
be preserved, and the total extent of the upstream area draining through
the site.
(5) The locations of all the existing and proposed utilities, sanitary
sewers, and waterlines within 50 feet of property lines.
(6) An overlay showing soil names and boundaries. This overlay shall
include a table on the map showing the recharge capabilities of each
soil represented on-site in inches per hour, and describe their recharge
or infiltration capabilities.
(7) Proposed changes to the land surface and vegetative cover, including
the type, location, and amount of impervious area that would be added.
(8) Proposed structures, roads, paved areas, and buildings.
(9) Final contours at intervals of two feet. In areas of steep slopes
(greater than 15%), five-foot contour intervals may be used.
(10)
The name of the development, the name and address of the owner
of the property, and the name of the individual or firm preparing
the plan.
(11)
The names of adjoining property owners and features within 100
feet of the property boundaries.
(12)
The date of the plan submission.
(13)
A graphic and written scale of one inch equals no more than
50 feet; for tracts of 20 acres or more, the scale shall be one inch
equals no more than 100 feet.
(15)
The total tract boundary and size with distances marked to the
nearest foot and bearings to the nearest degree.
(16)
Existing and proposed land use(s).
(17)
A key map showing all existing man-made features beyond the
property boundary that would be affected by the project.
(18)
Horizontal and vertical profiles of all open channels, including
hydraulic capacity.
(20)
A fifteen-foot-wide access easement around all stormwater management
facilities that would provide ingress to and egress from a public
right-of-way.
(21)
A note on the plan indicating the location and responsibility
for maintenance of stormwater management facilities that would be
located off-site. All off-site facilities shall meet the performance
standards and design criteria specified in this chapter.
(22)
A construction detail of any improvements made to sinkholes
and the location of all notes to be posted, as specified in this chapter.
(23)
A statement signed by the landowner, acknowledging the stormwater
management system to be a permanent fixture that can be altered or
removed only after approval of a revised plan by the Borough.
(24)
The following signature block for the Municipal Engineer:
"(Municipal Engineer), on this date (date of signature), has
reviewed and hereby certify that the Stormwater Management Site Plan
meets all design standards and criteria of the Jim Thorpe Borough
Watershed Act 167 Stormwater Management Ordinance."
(25)
The location of all erosion and sedimentation control facilities.
C. Supplemental information.
(1) A written description of the following information shall be submitted:
(a)
The overall stormwater management concept for the project.
(b)
Stormwater runoff computations as specified in this chapter.
(c)
Stormwater management techniques and best management practices
to be applied both during and after development.
(d)
Expected project time schedule.
(2) A soil erosion and sedimentation control plan, where applicable,
including all reviews and approvals, as required by PA DEP.
(3) A geologic assessment of the effects of stormwater runoff and infiltration
on sinkholes as specified in this chapter.
(4) The effect of the project (in terms of runoff volumes and peak flows)
on adjacent properties and on any existing municipal stormwater collection
system that may receive runoff from the project site.
(5) A declaration of adequacy and highway occupancy permit from the PA
DOT District Office when utilization of a PA DOT storm drainage system
is proposed.
D. Stormwater management facilities.
(1) All stormwater management facilities must be located on a plan with
maps and described in detail.
(2) Maps for groundwater recharge facilities must show the locations
of existing and proposed septic tank infiltration areas and wells.
A separation distance of no less than 20 feet shall be used between
any septic system and any facility used for stormwater management.
(3) All calculations, assumptions, and criteria used in the design of
the stormwater management facilities must be shown. If multiple facilities
are used in conjunction with each other, such as infiltration best
management practices with vegetation-based management practices, a
summary narrative shall be included describing any sequencing and
how the facilities are meant to function with each other to manage
stormwater runoff.
For the purpose of complying with this chapter, the steps below
shall be followed for stormwater management site plan submission.
For any activities that require a PA DEP joint permit application
and regulated under Chapter 105 (Dam Safety and Waterway Management)
or Chapter 106 (Floodplain Management) of PA DEP's Rules and
Regulations, require a PA DOT Highway Occupancy Permit, require approval
from the Army Corps of Engineers, or require any other permit under
applicable state or federal regulations, the permit(s) shall be part
of the plan.
A. The stormwater management site plan shall be submitted by the developer
as part of the preliminary plan submission.
B. A minimum of three copies of the stormwater management site plan
shall be submitted.
C. Distribution of the stormwater management site plan will be as follows:
(1) Two copies to the Borough accompanied by the requisite municipal
review fee, as specified in this chapter.
(2) One copy to the Municipal Engineer, qualified professional, or agency
designated by the Borough or per municipal ordinance required to review
preliminary and final subdivision or land development plans.
A disapproved stormwater management site plan may be resubmitted, with the revisions addressing the reviewer's concerns documented in writing, to the reviewer in accordance with §
377-18 of this chapter and be subject to review as specified in §
377-19 of this chapter. The applicable municipal review fee must accompany a resubmission of a disapproved stormwater management site plan.
