Construction Drawings - Minor Revisions

Construction Drawings - Minor Revisions

Construction Drawings – Minor Revisions (CD-MR) is a Water Resources-only process, developed to coordinate efforts within internal approving Business Units.

The Minor Revision (In Field) process does not fulfill the formal CCC requirement, where a full set of drawings set is required. Instead, it ensures all information required for fulfillment is captured. For an application to be considered minor:

It must only affect Water Resources, i.e., one Business Unit.

If the change requires a revision to the Subdivision Stormwater Management Report, it will not be considered minor.

Design changes to construction cannot be outside the construction boundary.

To be considered minor, all changes must be within the established construction boundary.

Line Assignment change(s) are not a minor revision.

Minor changes should not contravene any design guidelines or specifications.

What to Submit

How to Submit

Construction Drawings and CD-MRs are submitted electronically via POSEIDONOnline.

POSEIDONOnline electronic submissions must contain all required information and attachments for a review. If any information or required attachments are missing the submission will be rejected. No partial applications will be accepted.

POSEIDONOnline is accessed through The City's VISTA website, by selecting the Submit to Water link located on the left hand side of the VISTA main page.

The E-CD must be submitted first, before a CD Checklist can be submitted.

A CD identification number (CDID) is assigned when an E-CD is submitted via VISTA.

The CDID is required to submit the CD Checklist via POSEIDONOnline. Once the CDID has been received by the applicant, proceed with the submission of the CD Checklists.
