I'm considering building a new house in the mountains. How much property do I need to install a septic system and well?

It depends on the zoning of the area and when the lot was created or subdivided.


Individual Wells, Springs or Cisterns

  • Before November 10, 1973 = 1 acre minimum
  • Between November 10, 1973 and December 5, 1977 = 2 acre minimum
  • After December 5, 1977 = 5 acre minimum (but may be reduced to 3.5 acres per Section 4.2 B)

Public Water System

  • Before November 10, 1973 = 0.5 acre minimum
  • Between November 10, 1973 and December 5, 1977 = 1 acre minimum
  • After December 5, 1977 = 1 acre minimum
