Planning & Design

The Planning & Design (P&D) department is responsible for all plans that involve the improvement of a county road. These responsibilities include the development of the concept of the improvement, the preparation and/or review of detailed plans, the acquisition of the necessary easements and/or right-of-way, the preparation of the notes and quantities for the bidding process and the selection of a contractor to construct the improvements. After a contractor has been selected, the improvement project would be under the jurisdiction of the Permit & Construction department.

Capital Improvements

The Hamilton County Engineer prepares a two year capital improvement program. To see the current listing of projects click on the links below. Engineering projects are contracts to prepare detailed engineering plans for future bridge and roadway projects and the roadway and bridge projects are the proposed construction of improvements. The actual timing on the projects is dependent upon available financial leveraging to secure needed funding.
