Edward's hairstreakHabitat Related Measures to Augment Local Road Review


Street design and acceptance policies do not just have public safety and public works maintenance budget implications, but also have direct consequences for wildlife habitat. The manner in which towns accept roads will often determine how developers approach subdivision design. Limiting the length of dead end roads, or not accepting dead end roads unless they are part of a conservation subdivision, is often the only incentive needed by developers to design more habitat friendly projects. Additionally, a road ordinance can be crafted with design standards that can help to maintain existing habitat values and to minimize barriers to overland species travel.

Additional Information

Example Tools

  • Street Standards- A tool to reduce direct consequences for wildlife habitat that can result from some street design and acceptance policies.
  • Waterway and Wildlife Crossing Policy and Design Guide (Maine Department of Transportation)- Includes in-depth information regarding the physical and biological needs for wildlife passage on Maine's roads and guidance for the installation, replacement, repair and maintenance of both aquatic and terrestrial crossing structures including culverts, pipes, and bridges. Although the document was developed for Maine DOT projects with waterway crossings, direct wildlife habitat or travel corridor impacts, the design guidance can be adapted to similar municipal or private projects.
