Geographic Information System (GIS) Requirements for Multifamily, Commercial and/or Industrial Development, Right-of-Way Construction and/or Utility Improvements and Performing Plats and/or Short Subdivisions. Developers and or owners of multifamily, commercial and or industrial projects, developers required to construct right-of-way and or utility improvements and developers performing plats and or short subdivisions, shall submit to the city drawing files in the State Plane coordinate system as described below, in a version of AutoCAD and format suitable to the city public works director, accompanied by original mylars (record drawings) which indicate the building footprint(s), property lines, rights-of-way, easements, utilities, utility services, grading and all impervious surfaces. All changes from the original approved plans shall be clearly marked on the record drawing to reflect as-built conditions. The AutoCAD drawing files shall also reflect as-built conditions and shall be supplied in the format listed below:
The AutoCAD files shall be structured so that the following drawing entities are developed using a single polyline or circle that closes on itself, to create a polygon. The entities shall be placed on a unique layer as listed.

20. | Gas line shall run from valve to valve (two-inch gas line would be located on layer G2, three-inch on G3, etc.) | G(size) |
21. | Gas service stubs shall run from the tee to the end of the service | GSTUB |
22. | Gravel shoulders shall be represented by a line running along the outer edge of the shoulder area (two per road if applicable) | SHLD |
23. | Power lines shall run from transformer to riser or feeder line to riser | POW |
24. | Telephone lines shall run from riser to riser or manhole to manhole | TEL |
25. | Water lines shall run between valves and/or fittings (two-inch water lines would be located on layer WL2, three-inch on WL3, etc.) | WL(size) |
The following drawing entities shall be developed as single points representing the location of the center of the item they represent. The city will allocate the proper symbols to these points once the drawing is translated into the city's GIS. The points shall be placed on the proper layer as listed.
| Entity | Layer |
|---|
26. | Survey monument | MON |
27. | Set monument in case | SMON |
28. | Found monument in case | FMON |
29. | Set rebar for lot corner | LOTCOR |
30. | Existing property corner | PROPCOR |
31. | Point of tangency | PT |
32. | Point of curvature | PC |
33. | Electrical manhole | EM |
34. | Electrical transformer | ET |
35. | Electrical vault | EV |
36. | Fire hydrant | HYD |
37. | Gas valve | GV(size) |
38. | Luminaire (street light) | LUM |
39. | Street light pole | LTPOLE |
40. | Pull box for street light | LTBOX |
41. | Storm drainage catch basin | SDCB |
42. | Storm drainage curb inlet | SDCI |
43. | Sanitary sewer manhole | SSMAN |
44. | Sign | SIGN |
45. | Telephone manhole | TM |
46. | Telephone riser | TR |
47. | Cable TV riser | TVR |
48. | Water valve | VALV(size) |
49. | Double check valve assembly | DCV |
50. | Water meter | WM(size) |
51. | Blowoff assembly | BLOWOFF |
52. | Power pole | PPOLE |
53. | Utility vault | UVAULT |
54. | Air vacuum and release assembly | AIRVAC |
55. | Back flow prevention assembly | BFP |
The following drawing entities shall be developed as polylines. Start/end parameters are listed in the entity description. Each entity shall be placed on the proper layer as listed.
| Entity | Layer |
|---|
56. | Sanitary sewer force mains shall start at lift stations and terminate at discharge point | FM(size) |
57. | Sanitary sewer lines shall run between manholes as a single line. (eight-foot sewer lines shall be located on layer SS8) | SS(size) |
58. | Sanitary side sewer stubs shall run between main line and end of stub | SSTUB(size) |
59. | Storm drain lines shall run between catch basins as a single line. (12-inch storm drain lines shall be located on layer SD12, eight-inch on SD8, etc.) | SD(size) |
60. | Water service lines shall run from valve to end appurtenance or cap | WS(size) |
Any other unique features not listed above shall be given a descriptive layer name. A layer list shall be provided with the drawing files to indicate what additional layer names represent. All construction information and pertinent text information provided on the drawings shall be placed in a layer called REFTEXT. Associated leaders, dimension lines and arrows can also be placed in this layer.
Lines associated with node points (i.e., sewer lines and manholes, water lines and valves, etc.) shall be drawn with the end point of the line two drawing units away from the point it's associated with.
A complete set of project drawings and specifications shall be provided with the AutoCAD drawing files to provide data such as fire hydrant model number, pipe material type, valve end types, etc.
Lines that are intended to remain separate must be separated by a space greater than two drawing units. The AutoCAD drawing file shall be drawn with one drawing unit equals one foot and shall be supplied showing the complete project in one drawing file including any cross-referenced files. AutoCAD drawing files separated into different sheets will not be accepted. Drawing files shall be oriented with north at the top of the screen and shall be tied to the coordinate system utilized by the city's GIS. See the spatial reference guidance in subsection
B of this section. AutoCAD deliverables will be considered incomplete and as a result postpone project closeout until spatial reference requirements are met. Labor hours spent by the city GIS technician on project data integration will be charged to project accounts.
