A. Maine DOT’s Crossing Goals and Objectives

Through implementation of this policy and design guide, MaineDOT continues to support its goal of developing effective ways to build, repair and maintain the transportation infrastructure, while protecting important aquatic, wildlife and surface water resources. When examining whether aquatic organism, wildlife habitat, or hydrologic connectivity are compatible with new stream crossing structures, improvements to existing structures or location of new roadways, Maine DOT must balance the interrelated needs of the site, including regulatory, biologic, hydrologic, structural, and economic constraints. Objectives based on these various needs may include, but are not limited to, any of the following:

  • ™Locate and design projects to avoid and minimize adverse impacts to wetlands, natural stream channels, wildlife habitats, and other natural resources to the extent practicable and “feasible considering cost, existing technology and logistics based on the overall purpose of the project” (Maine Department of Environmental Protection’s Chapter 310, Wetland and Waterbodies Protection Rules, Sections 3(R) and 5(D));

  • ™Pass peak stream flows in accordance with Maine DOT’s best drainage practices;
  • ™Meet applicable regulatory standards and comply with state and federal guidance specific to water quality and aquatic and wildlife migration or movement corridors to the extent practicable;

  • Mitigate, to the extent practicable, unreasonable adverse impacts to protected natural resources as determined appropriate by regulatory agencies;

  • ™Consider potential impacts to private property, utilities and traffic;

  • ™Meet appropriate engineering standards and safety requirements; and

  • ™Provide reasonable life cycle costs.
