Surface Water Resources Information
The Hydrology Unit provides drainage and hydrology expertise to a variety of MaineDOT programs. The unit has updated the drainage design chapter of the Highway Design Manual to incorporate current design practices and the latest research in Maine hydrology. Unit staff perform hydrologic studies for highway and bridge projects, and assist in problem-solving at the division level. The unit also offers training to MaineDOT staff and consultants in MaineDOT drainage practice and policies.

Surface Water Quality Unit
The Surface Water Quality Unit has a multidisciplinary staff that provides technical assistance to the Department in erosion and sedimentation control, stormwater management, and other surface water concerns in the state of Maine. Unit staff offer training to MaineDOT staff and consultants in surface water quantity and quality concerns. They also assist the Maine Department of Environmental Protection's (MDEP) Nonpoint Source Training and Resource Center in training certified contractors in erosion control practices.
Through a stormwater memorandum of agreement (MOA) with the MDEP, the unit oversees the implementation of a temporary erosion and sediment control standard for all MaineDOT construction projects. Each year we provide report to the MDEP summarizing these activities.
The unit is also a primary contact for the general public regarding concerns with stormwater quality impacts of MaineDOT facilities.
