Digital Submission Standards for Computer Aided Drafting Files

As part of the City of Rohnert Park's commitment to convert all mapping to a digital format we now require that all final or parcel maps and commercial/industrial site improvement permits provide a digital map consisting of the following data prior to recordation/approval. If the developer/applicant is unable to provide the data the City will provide conversion services at a cost of $10 per lot.

The Data required is as follows:

• All property lines.
• All face-of-curb lines. (In the case of rolled curbs, back of curb data will be accepted.)
• All street centerlines (public and/or private)
• All new water infrastructure, (public and/or private) which will include: water mains, valves, air relief's, detector checks, hydrants, reducers, blow-offs, and meters.
• All new sewer infrastructure (public and/or private) which will include: sewer mains, manholes, clean-outs, and lift or pump stations.
• All new storm drain infrastructure (public and/or private) which will include: storm drain mains, inlets, catch basins, and manholes.
• Street lights (public and/or private) which will include: poles, pole numbers, and conduits.
• All new set street numbers.

This information must be separated into distinct layers using common names (example: water main, manhole, etc.) or a key must be provided showing which layer goes with which data as listed above.

The digital information must be submitted either in "DXF" or "DWG" file format on 31/2" floppy diskette(s). Compressed files will be accepted in "ZIP(tm)" Compression ONLY. Format platform will be DOS or WINDOWS 95.

In addition to the diskette, a hard copy plot must be provided at 1" = 100' 0" scale. The project engineer shall sign the plot as being an accurate representation of the data provided on the diskette(s). The City will review the digital data to verify that the plot is an accurate representation of the digital data and notify the project engineer of its acceptance prior to recordation.

Please be aware that the City will be using this data for the sole purpose of streamlining its basemapping.
