• Abstract:
  Recent discussions around State and federal stream crossing regulations have focused on resolving existing barriers ; to fish movement created by pipe culverts associated with transportation infrastructure. Approximately 30% of ; Maine has been surveyed for stream barriers through the joint efforts of state and federal fisheries agencies and non-government organizations, which have mapped this data via GIS. These same entities are currently working toward ; prioritizing identified barriers according to potential habitat value and species status. The resulting database contains ; location information, but does not differentiate crossings for which the state is responsible from those under local or ; private responsibility. This lack of distinction makes it near to impossible to quantify specific future costs to ; MaineDOT other than on a crossing by crossing basis. ; The overall project was focused on continued development of the Maine Barrier Database, integrating MaineDOT ; crossings with that database, and supporting the development of ; the Maine Stream Habitat Viewer http://mapserver.maine.gov/streamviewer/streamdocHome.html ; as a tool to be used by MaineDOT, municipalities and others for viewing aquatic habitat data in association with ; stream crossings. The final dataset developed for use by MaineDOT includes important attributes associated with ; fisheries habitat values, as well as cost estimates for evaluating addition of projects to work plans. ; There are two major outcomes from this work that are already benefitting MaineDOT. ; 1) Completion of GIS aquatic barrier work that was started under other sponsorship: The results were ; delivered to MaineDOT as ArcMAP coverages and to the Maine Office of GIS for incorporation into the Maine ; Stream Habitat Viewer. MaineDOT has been using both products on a regular basis. The products have been of ; great value in enabling the Environmental Office staff to deliver quick preliminary assessments of aquatic habitat ; that might affect MaineDOT projects. ; 2) Application of culvert replacement cost model for providing fish passage: Several years ago University of ; Southern Maine/Muskie School developed a cost model for culvert replacement. The focus was on replacement ; culverts that would be accepted as providing fish passage. This cost model was applied to data generated from his ; GIS data in (1) above. The results show order-of-magnitude implications for various replacement strategies.
