What a good response to plan check corrections has

General guidance, not Yamhill County’s own rules. Check its page before you resubmit.

• Answer every comment, in the reviewer’s order and numbering, so nothing is missed.
• Say plainly what you changed for each comment, or why no change is needed.
• Name the sheet and detail where each change is, so the reviewer can find it fast.
• Mark changes on the drawings (clouds or deltas are common) and keep sheet numbers the same.
• Send the response letter, the revised drawings and any new calculations together.
