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.
