Stream Permitting

In 1975, the Legislature enacted the Natural Streambed and Land Preservation Act, aka the 310 Law. This means that any person, agency, contractor, or firm that is proposing a project that may alter or modify the beds or banks of a perennial stream, river, or spring, must first obtain a 310 permit through the Gallatin CD.

The purpose of the 310 law is to ensure that projects are carried out in a manner that does not damage the resource or affect adjoining landowners.

The Gallatin CD Board of Supervisors meets once a month to make decisions on 310 applications. Board meetings are held on the third Thursday of each month; applicants wishing to be on that month’s agenda should submit their completed 310 application to the District office on the first Thursday of the month. Please refer to the schedule under 310 permitting for a complete schedule.
