Start with the right office
Have the parcel address, a survey and a short description of the whole project ready. These are public agency contacts, not contractor referral lines.

Build one file for the whole scope
Start with the property-records checklist, then record the wall, dock, lift, drainage and access changes together. Keep the dated responses from each office with your drawings so a later design change does not disappear between separate conversations.
Use the benthic-survey guide to prepare habitat questions and the contractor verification guide before discussing a contract. A useful submission describes existing conditions and proposed work distinctly.
