Design Criteria & Improvement Standards

The Design Criteria and Improvement Standards (DCIS) Manual is divided into two parts, Part I - Planning Design Criteria, and Part II - Engineering Design Criteria and Standards. This Manual was developed to work in conjunction with the Douglas County Master Plan and the Douglas County Development Code (Title 20).

The Board of County Commissioners approved revised standards for residential driveways at the April 18, 2019 board meeting.  The document is available at the link below.
