Utility Services

The purpose of Computer Aided Drawing(CAD) Submittal Standards is to depict water, sewer and reclaim infrastructure data in an electronic format that can be used directly with CAD and GIS software.Providing a CAD file to consultants will reduce or eliminate the need for consultants to convert information from PDF maps to CAD data.Requiring a CAD file from consultants will reduce or eliminate the City’s need to convert information from PDF sheets to GIS data.

The Department of Utility Services will provide to consultants upon request a CAD file containing existing water, sewer and reclaim data which follow the standards that will be required in return. The CAD Submittal Standards outlined below apply only to water, sewer and reclaim asset data applicable to the City of Henderson Department of Utility Services.

CAD files submitted to the City must adhere to the following standards:

1. Submit one and only one AutoCAD DWG file that contains data specific to water, sewer and reclaim utilities only and must be named with an underscore UT at the end of filename (i.e.ANYPROJECTNAME_UT.DWG) to be accepted.
2. DWG file must match the information represented in the mylars at the time of submittal.
3. DWG file must be defined in the NAD83 State Plane Nevada East Survey Feet(FIPS 2701; WKID 3421; EPSG 3421) coordinate system.
   1. 
4. The CAD data must be stored using simple points, polylines and closed polylines.
5. Each drawing layer in the CAD file may only store a single data type. For example, if a layer is created to store proposed water valves, only simple points representing water valves may be stored in that layer. Extraneous information such as text blocks, annotation, leader lines, etc.may not be stored in the data layer.
6. CAD data stored in the CAD layers must be contiguous and coincident where appropriate. For example, a sewer main pipe will be drawn using a polyline that extends to and whose endpoint is coincident with the end of the adjoining sewer main pipe.The coincident endpoints will also be coincident with the point representing the center of the sewer manhole located between the two sewer main pipes.
7. CAD layers must adhere to the following naming convention.
   1. A prefix of “EX_", "PR_", or "DM_” will indicate whether the layer will store Existing, Proposed, or Demolition utility data.
   2. A “W_” “R_” or “S_” will indicate whether the layer will store data associated with the water system, reclaim water system, or sewer system respectively.
   3. The layer name will follow to indicate what type of data is stored in the layer, for example, MAIN for main pipes or LATERAL for lateral pipes.For example, PR_S_MAIN will be the layer storing polylines representing proposed sewer mains.

      Prefix	System	Name	Feature Type	Description
      EX_, PR_, DM_	W_, R_, S_	MAIN	Polyline	Represents main pipe centerline.Drawn with straight polyline consisting of two end points. End points will be coincident with points representing a system valve, hydrant, meter, CCCD, pump assembly, reservoir, lift station, network structure, or fitting of all types except wye and true wye.
      EX_, PR_, DM_	W_, R_, S_	LATERAL	Polyline	Represents lateral pipe centerline.Drawn with straight polyline consisting of two end points. End points will be coincident with points representing a system valve, hydrant, meter, CCCD, network structure, cleanout, or fitting of all types.
      EX_, PR_, DM_	W_, R_, S_	CASING	Closed Polyline	Represents extents of pipe encasement, typically drawn as a rectangular, closed polyline overlapping with a MAIN or LATERAL pipe.
      EX_, PR_, DM_	W_, R_, S_	EASEMENT	Closed Polyline	Represents extents of easement drawn as a closed polyline.
      EX_, PR_, DM_	W_, R_, S_	SYSTEM_VALVE	Point	Represents horizontal center of valve operating nut
      EX_, PR_, DM_	W_	HYDRANT	Point	Represents horizontal center of hydrant assembly
      EX_, PR_, DM_	W_, R_	METER	Point	Represents horizontal center of meter
      EX_, PR_, DM_	W_, R_	CCCD	Point	Represents horizontal center of the cross connection control device, or backflow device(types below)
      EX_, PR_, DM_		UTIL_STRUCTURE	Closed Polyline	Represents structure horizontal extents
      EX_, PR_, DM_	S_	MANHOLE	Point	Represents horizontal center of manhole (not lid)
      EX_, PR_, DM_	W_, R_, S_	FITTING	Point	Represents horizontal center of fitting (types below)
      EX_, PR_, DM_	S_	SOGI	Point	Represents horizontal center of sand, oil and grease interceptor(types below)
      EX_, PR_, DM_	S_	CLEANOUT	Point	Represents horizontal center of sewer cleanout(types below)

8. CAD entities must include attribution that is digitally transferable. One of three options is recommended:
   1. Include CAD Object Data attached to each CAD entity with fields and values following the layer attribute table below. For an example, please see the CAD template of existing utility data provided by COH DUS.
   2. Include Civil 3D Extended Data attached to each CAD entity with fields and values following the layer attribute table below.
   3. Use the free ArcGIS for AutoCAD downloadable plug-in application for AutoCAD to enter values following the format provided by COH DUS.Note: this option requires a DWG template (seed) file created for use with this application.
