[Ord. 2013-04, 12/18/2013, § 202]
Engineering or site plans or drawings that document the actual locations, dimensions and elevations of the improvements, and building components, and changes made to the original design plans. The final version of these documents, or a copy of same, are signed and sealed by a qualified licensed professional and submitted to the municipality at the completion of the project, as per the requirements of § 19-502 of this chapter as "final as-built plans."
Activities, facilities, designs, measures, or procedures used to manage stormwater impacts from regulated activities, to provide water quality treatment, infiltration, volume reduction, and/or peak rate control, to promote groundwater recharge, and to otherwise meet the purposes of this chapter. Stormwater BMPs are commonly grouped into one of two broad categories or measures: "structural" or "nonstructural." In this chapter, nonstructural BMPs or measures refer to operational and/or behavior-related practices that attempt to minimize the contact of pollutants with stormwater runoff whereas structural BMPs or measures are those that consist of a physical device or practice that is installed to capture and treat stormwater runoff structural BMPs include, but are not limited to, a wide variety of practices and devices from large-scale retention ponds and constructed wetlands to small-scale underground treatment systems, infiltration facilities, filter strips, low impact design, bioretention, wet ponds, permeable paving, grassed swales, riparian buffers, forested buffers, sand filters, detention basins, and manufactured devices. Structural stormwater BMPs are permanent appurtenances to the site.
Act 394 of 1937, P.L. 495, 35 P.S. § 691.1 et seq., as amended.
A plan written by a planner certified by NRCS that identifies conservation practices and includes site specific BMPs for agricultural plowing or tilling activities and animal heavy use areas.
The outside bark diameter of a tree at breast height which is defined as 4 1/2 feet (1.37 m) above the forest floor on the uphill side of the tree.
That land area contributing runoff to a single point (including, but not limited to, the point/line of interest used for hydrologic and hydraulic calculations) and that is enclosed by a natural or man-made ridge line.
(A) (noun) A slope, usually of a road, channel, or natural ground, specified in percent and shown on plans as specified herein. (B) (verb) To finish the surface of a roadbed, the top of an embankment, or the bottom of an excavation.
Water that occurs in the subsurface and fills or saturates the porous openings, fractures and fissures of under-ground soils and rock units.
A surface that has been compacted or covered with a layer of material so that it prevents or is resistant to infiltration of water, including, but not limited to, structures such as roofs, buildings, storage sheds; other solid, paved or concrete areas such as streets, driveways, sidewalks, parking lots, patios, tennis or other paved courts; or athletic playfields comprised of synthetic turf materials. For the purposes of determining compliance with this chapter, compacted soils or stone surfaces used for vehicle parking and movement shall be considered impervious. Surfaces that were designed to allow infiltration (i.e., areas of porous pavement) will be considered on a case-by-case basis by the Municipal Engineer, based on appropriate documentation and condition of the material, etc.
Development in accordance with § 503(1.1) of the Pennsylvania Municipalities Planning Code (as amended).
A seasonal high water table, whether perched or regional, determined by direct observation of the water table or indicated by other subsurface or soil conditions.
Act of, July 31, 1968, P.L. 805, No. 247, 53 P.S. § 10101 et seq., as amended, the Pennsylvania Municipalities Planning Code, Act 247.
Franklin Township, Chester County, Pennsylvania.
O & M means "operation and maintenance." See Part 7.
PABMP MANUAL
Pennsylvania Stormwater Best Management Practices Manual, as amended.
Any discernible, confined, and discrete conveyance including, but not limited to, any pipe, ditch, channel, tunnel, or conduit from which stormwater is or may be discharged, as defined in state regulations at 25 Pa.Code § 92.1.
A method of estimating the runoff in a drainage basin at a specific point and time by means of the rational formula Q = cia, where "Q" is flow in cubic feet per second, where "c" is a runoff coefficient based on type of surface, set forth in Appendix 19-C of this chapter, "i" is the rainfall intensity in inches per hour, and "a" is the area in acres.
Any activity involving earth disturbance subject to regulation under 25 Pa.Code, Chapter 92.a, Chapter 102, or the Clean Streams Law.
RETURN PERIOD/STORM FREQUENCY
The average interval, in years, within which a storm event of a given magnitude can be expected to occur one time. For example, twenty-five-year return period rainfall would be expected to occur on average once every 25 years; or stated in another way, the probability of a twenty-five-year storm occurring in any one year is 0.04 (i.e., a four-percent chance).
A method of runoff computation developed by NRCS that is based on relating soil type and land use/cover to a runoff parameter called curve number (CN) as set forth in Appendix 19-C to this chapter.
The regulatory requirements to protect, maintain, reclaim, and restore water quality under 25 Pa.Code and the Clean Streams Law.
Act of October 4, 1978, P.L. 864, No. 167, 32 Pa.C.S.A. § 680.1 et seq., as amended.
The plan prepared by the applicant or its representative, in accordance with the requirements of Part 4 of this chapter, indicating how stormwater runoff will be managed at a particular site in accordance with this chapter, and including all necessary design drawings, calculations, supporting text, and documentation to demonstrate that Part requirements have been met, herein referred to as "SWM site plan." All references in this chapter to "final" or "approved" SWM site plans shall incorporate the approved SWM site plan and all subsequent approved revisions thereto.
The division or re-division of a lot, tract, or parcel of land as defined in the Pennsylvania Municipalities Planning Code, Act of July 31, 1968, P.L. 805, No. 247 (as amended).
Subdivision and Land Development Ordinance of the municipality, as amended.
Highest point of elevation of the bank of a stream or channel cross-section at which a rising water level just begins to flow out of the channel and into the floodplain.
The upper most level of saturation of pore space or fractures by groundwater. Seasonal high water table refers to a water table that rises and falls with the seasons due either to natural or man-made causes.
Any land area of at least 0.25 acre with a natural or naturalized ground cover (excluding manicured turf grass) and that has an average density of two or more viable trees per 1,500 square feet with a DBH of six inches or greater and where such trees existed at any time within three years of the time of land development application submission of the proposed project. The land area to be considered woods shall be measured from the outer drip lines of the outer trees.
