Development "within a half mile and draining to" SA waters; a half mile buffer should delineate all possible areas. Very stringent density thresholds apply here. Development "within one mile of and draining to" HQW waters. However, this criterion does not apply to WS-I, WS-II, and coastal (where many HQW are SA). Development "draining to" ORW waters (statewide). These areas may be smaller than 14-digit hydrologic units. Note that some watersheds have special management strategies tantamount to ORW requirements.As of October 2008, the State Stormwater Program (Coastal and non-Coastal) requirements satisfy Phase II requirements.
WS-I & WS-II: Technically, these are subject to the State SW Program above, but the Water Supply Program at the local government level satisfies the HQW requirement (i.e., there is no need to get a State SW permit from the Regional Office). Requirements will also vary based on whether the watershed is a Critical Area (CA) or Protected Area (PA). However, where WS-I & WS-II areas overlap ORWs, both the DWQ Regional Office and the Local Government should be contacted (this is a correction from previous years, verified by J. Ventaloro of DWQ.) WS-III & WS-IV: These areas are different from the State SW program above but do have stormwater requirements at the local government level. Where WS-III & WS-IV areas overlap HQWs, ORWs, or coastal counties, both the DWQ Regional Office and the Local Government should be contacted.WS-I through WS-IV requirements in the WS Protection Program satisfy Phase II requirements. Where WS-I and WS-II overlap ORWs, both State SW Program and Local Program requirements apply. Where WS-III and WS-IV overlap HQW/ORW/Coastal Counties, both State SW Program and Local Program requirements apply.
The 15 largest local governments implement this program in the Neuse Basin (only portions within the basin):Cary, Smithfield, Durham, Wilson, Garner, Goldsboro, Havelock, Kinston, New Bern, Raleigh, as well as Orange County*, Durham County*, Johnston County*, Wake County*, and Wayne County*.
Six municipalities and five counties implement this in the Tar-Pamlico Basin (only portions within the basin):Greenville, Henderson, Oxford, Rocky Mount, Tarboro, and Washington. The counties are: Beaufort*, Edgecombe*, Franklin*, Nash*, and Pitt*. *Only applicable to areas under jurisdiction of respective county (i.e., unincorporated areas). Both the Neuse and Tar-Pamlico NSW strategy programs satisfy Phase II requirements. However, these programs do not satisfy State SW or WS requirements.

These data are intended to assist government agencies and their constituents in identifying which stormwater permitting requirements, if any, apply to a given location in North Carolina. This data set includes attributes relating to stormwater programs (nutrient management strategy areas/local governments, water supply watersheds, high quality and outstanding waters areas, etc.) and jurisdictions, including federally managed areas (e.g., military bases).

Some CONTACT field records that include military base names need to be shortened to avoid truncated text in the info. Some records for ORW watersheds on the coast that are also in Phase II cities (e.g., Wilmington) need revision to send user to local authoritywho will permit through Post-construction prog.
Some [NOTE] field records need to be shortened to avoid truncated text in the info. This includes changing WS contact URL to just 'WS Prog' before making edits so that watershed name fits. Reconcile any records where SA buffers extend into non-CAMA county (e.g., Jones Co.) and revise fields appropriately. Select and note USMP cities in [NOTE] field; verify with Regional Office who permits in coastal areas. Screen areas within federally managed lands to ensure some indication to contact military where needed. Modified TYPE, NOTE, and/or CONTACT where appropriate./*New Jordan Lake Watershed SW Rules*/

NC Department of Transportation GIS Unit, 2010, County boundaries in North Carolina.
The attributes for the base geospatial layers used in the model have beeen checked for accuracy in terms of watershed identifiers, county names, municipal names, municipal population, urbanized area names, and Phase II status of jurisdictions.
Base layers used in the model were mapped at a scale of 1:24,000 or better to be consistent with National Map Accuracy Standards. The digital files were plotted and overlayed to the originals and needed line corrections were made to within one line width.
There is no vertical dimension to this data layer.
This data layer represents stormwater jurisdiction within North Caroilna based on the best available geospatial data relating to Stormwater Phase II municipal boundaries, planning jurisdictions, municipal spheres of influence represented by urbanized areas (Census 2000) and buffers of municipal boundaries based on US EPA criteria, and other local and state stormwater programs related to nutrient sensitive waters, water supply watersheds, high quality water and outstanding resource water watersheds, the NC Coastal Area Management Act, and other watersheds where special stormwater requirements apply. The only base geospatial layer that is incomplete is the planning jurisdiction (extra territorial jurisdiction or ETJ) layer that lacks digital representations for municipalities in New Hanover and Henderson Counties (not available in digital format).
Original processing: using ESRI's ARC/INFO GIS software, the dataset was developed using Model Builder and the Spatial Analyst extension. The model processed statewide datasets or subsets of statewide datasets to represent stormwater jurisdiction within the boundaries of North Carolina.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None.
- Use_Constraints:
- It is important to remember that a local government may choose to pass ordinances that are above and beyond what existing stormwater programs or Phase II requires. A local government may choose to pass ordiinances in areas outside of Phase II areas. Also, city limits and extraterritorial jurisdictions (ETJ) may have changed since this dataset was created. Also, water supply watersheds or other water quality delineations may have changed between updates of this dataset. Therefore, users of this dataset should check for specific local government requirements to verify the information represented in this dataset. Acknowledgement of products derived form this data set should cite the following: The sources of the stormwater reference data are mapped at a scale of 1:24,000 or better, implying horizontal error plus or minus 40 feet. This representation is intended as a guide to persons seeking stormwater permits and to permitting authorities. While efforts have been made to ensure that these data are accurate and reliable within the state of the art, CGIA cannot assume liability for any damages or misrepresentation caused by any inaccuracies in the data or as a result of changes to the data caused by system transfers.
