Nitrogen rules in Eastham
MassDEP's designated Natural Resource Nitrogen Sensitive Area layer does not list an estuary system for Eastham. That does not automatically mean a given property is outside a designated area, and it does not change the Title 5 inspection requirement that applies on any sale.
What the town is building
Eastham was among the towns funded in the April 2026 Water Protection Fund round.
Eastham sits on the later designation date, so its timeline runs from September 2023 rather than July 2023.
