Description: This feature class contains features mapped to represent storm water blind junctions which are structures designed to accomodate the convergence of storm drainage pipes without an inlet or manhole access to the structure. The GIS data herein have been incorporated by SGS during Phase I as derived from plans (see process steps) or surveyed by SGS during Phase II. All data herein are identified as to their source (Scanned Hardcopy Plan, AutoCAD data, NCAGR Redline Drawing, Mapping Grade GPS Survey, and Survey Grade GPS Survey).

Description: This feature class contains features mapped to represent storm water curb inlets which are drainage structures situated concurrent with curb and gutter infrastructure.All inverts related data fields house data derived from the original AutoCAD or hardcopy plan source, are not the result of SGS surveys, and have not been modified in any manner by SGS. This data may be incomplete and/or incorrect. Rim elevations may be referenced to NGVD 29. All SGS surveyed positions are NAD 1983 (2011), NAVD 88 positions as represented by the Easting, Northing, and Elevation data fields. If a feature originally derived from AutoCAD or a hardcopy plan has been surveyed by SGS, the Easting, Northing, and Elevation data fields are the result of the SGS survey, with inverts related data fields remaining a result of the original source.For invert elevation attributes for inlet and outlet pipes, the protocol utilized herein for identifying pipe # is to number them ascending in a clockwise fashion from the outlet pipe. For example, the outlet pipe is the outlet pipe and the inlet pipe that is first in a clockwise fashion from a plan view perspective is pipe #1, the next is pipe #2, and so on. This protocol is designed to identify which pipe is being referred to for inverts via attribute fields.For storm water, inverts are recorded from AutoCAD or hardcopy plans only, are recorded only if that data are provided on the plans, and are not recorded for infrastructure surveyed in the field by SGS at the request of NCAGR. Whatever data is available via plans will be entered. In this case certain information may be absent due to the addition of infrastructure subsequent to the plan date or due to incomplete plans. If invert attributes are derived from plans and the plans do not specify the difference between 2 pipes of the same dimension they will be entered without verifying that they follow the clockwise protocol.The GIS data herein have been incorporated by SGS during Phase I as derived from plans (see process steps) or surveyed by SGS during Phase II. All data herein are identified as to their source (Scanned Hardcopy Plan, AutoCAD data, NCAGR Redline Drawing, Mapping Grade GPS Survey, and Survey Grade GPS Survey).
