The SCM Operation and Maintenance Plan <br /> must be attached to the SCM Operation and Maintenance Agreement (as "Attachment A") and shall meet <br /> the requirements of the most current version of the NCDEQ Stormwater Design Manual. <br /> Stormwater, SCM Performance Guarantee294 <br /> A financial assurance instrument used to guarantee the complete construction of a Stormwater Control <br /> Measure (SCM) in conformance with the approved Stormwater Management Plan (SMP). The SCM <br /> Performance Guarantee instrument shall be secured and posted by the owning entity of the Stormwater <br /> Control Measure (SCM), and shall meet the requirements of SL 2019-79 (SB 313). <br /> Stormwater, Stormwater Management Plan (SMP)295 <br /> A set of plans and supporting calculations prepared and sealed bV a North Carolina registered <br /> professional engineer or landscape architect (to the extent that the General Statute Chapter 89A allows), <br /> detailing how a proposed development will meet the requirements of Section 6.14 of this Ordinance.

Streams are identified by <br /> any of the following means: <br /> a) Shown as solid blue lines or as broken blue lines on the USGS Quadrangle maps, <br /> b) Shown as a water feature in the Orange County Soil Survey, or <br /> c) A water feature identified by a field determination of County staff trained in surface water <br /> identification through the North Carolina Division of Environmental Quality(NCDEQ). <br /> Stream buffers shall extend around the perimeter of all other water features if any portion of the stream <br /> buffer touches the water feature. Disputes pertaining to water feature identification decisions by County <br /> staff shall be filed directly to the NCDEQ. <br /> Stream, Ephemeral (Stormwater) <br /> A feature that carries only stormwater runoff 296in direct response to precipitation with water flowing only <br /> during and shortly after large precipitation events. An ephemeral stream may or may not have a well- <br /> defined channel, the aquatic bed is always above the water table, and stormwater runoff is the primary <br /> source of water. An ephemeral stream typically lacks the biological, hydrological, and physical <br /> characteristics commonly associated with continuous or intermittent conveyance of water. <br /> Stream, Intermittent <br /> A well defined channel that contains water for only part of the year, typically during winter and spring <br /> when the aquatic bed is below the water table. The flow may be heavily supplemented by stormwater <br /> 293 NEW DEFINITION—this definition has been added in order to support applicable stormwater section(s)of this <br /> Ordinance. <br /> 294 NEW DEFINITION—this definition has been added in order to support applicable stormwater section(s)of this <br /> Ordinance. <br /> 295 NEW DEFINITION—this definition has been added in order to support applicable Stormwater section(s)of this <br /> Ordinance. <br /> 296 Consistent use of"stormwater runoff'. <br /> Orange County, North Carolina—Unified Development Ordinance Page 10-56 <br />
