STORMWATER MANAGEMENT FACILITY
Any structure, natural or man-made, that, due to its condition, design or construction, conveys, stores, or otherwise affects stormwater runoff. Typical stormwater management facilities include, but are limited to, detention and retention basins, open channels, storm sewers, pipes, infiltration structures, and other BMPs.
STREAMS

B. 
STREAM, EPHEMERALA reach of stream that flows only during and for short periods following precipitation, and flows in low areas that may or may not be a well-defined channel. Ephemeral stream beds are located above the water table year-round. Groundwater is not a source of water for the stream. Some commonly used names for ephemeral streams include "stormwater channel," "drain," "swale," "gully," "dry stream channel," "hollow," or "saddle."
C. 
STREAM, INTERMITTENTA reach of stream that flows only during wet periods of the year and flows in a continuous well-defined channel. During dry periods, when the water table is depressed by seasonal activity or drought, intermittent streams may go down to a trickle of water and make it appear dry when in fact there is water flowing through the stream bottom or "substrate."
D. 
STREAM, PERENNIAL or WATERCOURSE, PERENNIALA body of water in a channel that flows throughout a majority of the year in a defined channel and is capable, in the absence of pollution, drought, or man-made stream disturbances, of supporting a benthic macroinvertebrate community that is composed of two or more recognizable taxonomic groups of organisms, large enough to be seen by the unaided eye and can be retained by a U.S. Standard No. 30 sieve (28 meshs per inch, 0.595 mm openings) and live at least part of their life cycles within or upon available substrates in a body of water or water transport system. A perennial stream can have Q7-10 flow of zero. For the purposes of this chapter, a perennial stream includes lakes and ponds.
STREET, ROAD or HIGHWAY
Includes streets, avenues, boulevards, roads, highways, freeways, parkways, lanes, viaducts, or any other ways used or intended to be used by vehicular traffic or pedestrians, whether public or private, which are identified on the legally adopted Township street or highway plan or the Official Map, together with all necessary appurtenances, including bridges, rights-of-way and traffic control improvements. The term shall not include the interstate highway system.
A. 
EXPRESSWAYHighways designed for large volumes of high-speed traffic with access limited to grade separated intersections.
B. 
LOCAL ACCESS STREETSThose used primarily to provide access to abutting properties.
C. 
COLLECTOR STREETSStreets which give minimal emphasis to travel mobility, which is characterized by low travel speeds, full land access, neighborhood penetration, and which serve minor traffic generators, such as local elementary schools, small individual industrial plants, offices, commercial facilities and warehouses not served by principal or minor arterials.
D. 
ARTERIAL STREETSThose serving large volumes of comparatively high-speed and long-distance traffic, and include facilities classified as main and secondary highways by the Pennsylvania Department of Transportation.
E. 
MARGINAL ACCESS STREETSMinor streets, parallel and adjacent to arterial streets, providing access to abutting properties and control of intersections with the arterial street.
F. 
CUL-DE-SACA minor street intersecting another street at one end and terminated at the other by a vehicular turnaround.
