Article 10: Definitions
<br /> Section 10.1: Definitions
<br />
<br />Orange County, North Carolina – Unified Development Ordinance Page 10-65
<br />
<br />A system of wastewater collection, treatment, and disposal in single or multiple components, including
<br />ground absorption systems, non-discharge systems, and systems that discharge effluent to the surface
<br />waters, and any other system as may be permitted by the Orange County Health Department or the State
<br />of North Carolina. (ref. NCGS Article 11, Chapter 130A)
<br />Waterbody, Perennial
<br />A natural or constructed basin that stores surface water permanently at depths sufficient to preclude
<br />growth of rooted plants, including lakes, ponds, sounds, non-stream estuaries, and oceans. For the
<br />purpose of stormwater provision of this Ordinance, the waterbody must be part of a natural drainageway
<br />(i.e. connected by surface flow to a stream).
<br />Water-Dependent Structure
<br />Any structure for which the use requires access to or proximity to or citing within surface waters to fulfill its
<br />basic purpose, such as boat ramps, boathouses, docks and bulkheads. Ancillary facilities such as
<br />restaurants, outlets for boat supplies, parking lots and commercial boat storage areas are not water-
<br />dependent structures.
<br />Water Feature
<br />A prominent aspect or characteristic of a geographic area that exhibits verifiable evidence of a presence
<br />of water in the soil. Examples of water features include, but are not limited to, perennial and intermittent
<br />streams, lakes, ponds, reservoirs, springs, artesian wells, irrigation wells, marshes or swamps, wetlands,
<br />and natural drainage ditches (non-ephemeral).
<br />Water surface elevation (WSE)
<br />The height, in relation to mean sea level, of floods of various magnitudes and frequencies in the
<br />floodplains of coastal or riverine areas.53
<br />Watercourse
<br />A lake, river, creek, stream, wash, channel or other topographic feature on or over which waters flow at
<br />least periodically. Watercourse includes specifically designated areas in which substantial flood damage
<br />may occur.
<br />Water Supply, Public
<br />A water supply system that serves a city or town located partly or entirely within Orange County that has a
<br />population in excess of 2,500.
<br />Water Supply Watershed (or Protected Watershed)
<br />Land that drains to existing reservoirs which are public water supplies or potential reservoir sites or
<br />stream intakes which have been designated for protection. All such lands have been classified by the
<br />Environmental Management Commission as WS-II, WS-III or WS-IV watersheds and require protection in
<br />accordance with the State Mandate. (See definition for “State Mandate”).
<br />Water Supply Watershed Critical Area, County Designated
<br />The land area within one-half mile of the normal pool elevation (or designated elevation) of an existing
<br />Class II water supply reservoir, or the ridgeline of the watershed, whichever is less; and the land area
<br />within one-half mile of the normal pool elevation (or designated elevation) of a proposed water supply
<br />reservoir designated for protection, or the ridgeline of the watershed, whichever is less; and the area
<br />within one-half mile of streams flowing into Class I reservoirs, as designated for protection within this
<br />Ordinance.
<br />Water Supply Watershed Critical Area, State Required
<br />The land area within one-half mile of the normal pool elevation of water supply reservoirs in which an
<br />intake is located (i.e., Class I reservoirs), or the ridgeline of the watershed, whichever is less.
<br />
<br />53 As we are not in a coastal area there is no need to reference same in our definition(s) section.
