1.
All SWM site plan materials shall be submitted to the Township in a format that is clear, concise, legible, neat, and well organized; otherwise, the SWM site plan shall not be accepted for review and shall be returned to the applicant. The following items shall be included in the SWM site plan:

General description of 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 and assumptions and criteria used in the design of the stormwater management facilities.
(4)
A determination of site conditions in accordance with the BMP Manual. A detailed site evaluation shall be completed for projects proposed in areas of carbonate geology or karst topography, and other environmentally sensitive areas, such as brownfields.
(5)

(7)
Expected project time schedule.
(8)
Development stages (project phases) if so proposed.
(9)
An operation and maintenance (O&M) plan for all existing and proposed physical stormwater management facilities. This plan shall address long-term ownership and responsibilities for O&M as well as schedules and costs for O&M actives.
(10)
A justification must be included if BMPs other than green infrastructure methods and LID practices are proposed to achieve the volume, rate, and water quality controls under this chapter.
(11)
Provisions for permanent access and/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.
B.
Maps. Map(s) of the project area shall be submitted on 24-inch x 36-inch sheets and/or shall be prepared in a form that meets the requirements for recording at the offices of the Recorder of Deeds of Monroe County. The contents of the map(s) shall include, but not be limited to:
(1)
A location map at a scale of 1" = 2,000' or less showing the location of the project relative to highways, municipalities, or other identifiable landmarks.
(2)
The name of the development, the name and address of the applicant, the address of the property, and the name and address of the individual or firm preparing the SWM site plan.
(3)
The date of submission.
(4)
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.
(5)
A North arrow, with a notation of whether it is true or magnetic.
(6)
The boundaries of the total property and, if different, development site boundary and size with distances marked to the nearest foot and bearings to the nearest degree.
(7)
Names, numbers and rights-of-way widths of adjoining roads.
(8)
Locations of existing streams, lakes, ponds, wetlands or other waters of this commonwealth within the development site.
(9)
Locations of wooded areas and tree masses, buildings and structures, rock outcrops, paved areas, sidewalks, culverts, storm sewers, swales, utilities, and all other significant man-made features.
(10)
The locations of existing and proposed on-lot wastewater facilities and water supply wells.
(11)
Floodplain and floodway boundaries, riparian buffers, existing drainage courses, areas of natural vegetation to be preserved, the total extent of the upstream area draining through the site, and pre- and post-development drainage areas.
(12)
Existing and proposed contours at intervals of two feet. In areas of steep slopes (greater than 15%), five-foot contour intervals may be used.
(13)
The locations of all existing and proposed utilities, sanitary sewers, and water lines within 50 feet of property lines.
(14)
The location(s) of any wellhead protection zones.
(15)
Soil names, boundaries, hydrologic group, and limitations.
(16)
Limits of earth disturbance, including the type and amount of impervious area that would be added.
(17)
Proposed structures, roads, paved areas, impervious surfaces, buildings and other land cover.
(18)
Existing and proposed land use(s).
(19)
A key map showing all existing man-made features beyond the development site boundary that would be affected by the project.
(20)
Location of all open channels.
(21)
Overland drainage patterns and swales.
(22)
The location of all erosion and sediment control facilities.
(23)
The location of permanent access and/or maintenance easements for all physical SWM BMPs.
(24)
Plans, profiles, and details of all SWM BMPs, including, but not limited to, drainage structures, pipes, open channels, and swales.
(25)
A note on the plan indicating the location and responsibility for maintenance of stormwater management facilities that would be located off-site.
(26)
A statement, signed by the applicant, acknowledging that any revision to the approved SWM site plan must be approved by the Township and that any revised erosion and sediment control plan must be submitted to the Conservation District for a determination of adequacy.
(27)
The following signature block for the qualified professional:
"I, [qualified professional], on this date, [date of signature], hereby certify that the SWM site plan meets all design standards and criteria of the [name of applicable Act 167 Plan] and Stroud Township Stormwater Management Ordinance."
(28)
Isolation distances from wells, buildings, and septic systems, as noted in the Pennsylvania Stormwater Best Management Practices (BMP) Manual.
C.
