Bournes Pond

Bournes Pond

A designated Natural Resource Nitrogen Sensitive Area covering parts of Falmouth, Mashpee.

On MassDEP's address map, this area is called Great, Green, and Bournes Pond Embayment Systems. That is the name you will see in the popup if you click your property on the map, and it is the name to look for — not the shorter one at the top of this page.

The same area on the map also covers Green Pond, Great Pond. MassDEP's application table lists those separately from this one; the map does not divide them. For a property here, that distinction does not change the answer — each town's filing is the same across the whole area.

What each town filed

TownFilingTransmittal
Falmouth Notice of Intent 23-WP94-0014-APP
Mashpee De Minimis application 24-WP98-0002-APP
The towns here did not file the same way. Two properties in this watershed can sit in different legal positions depending on which side of a town line they fall. If you are near a boundary, the town matters as much as the watershed.

What the filings mean

Notice of Intent

The town has filed a Notice of Intent: a commitment to apply for a Watershed Permit later, on a schedule approved by MassDEP. It pauses the clock. It does not stop it.

De Minimis application

The town has applied for a De Minimis Load Exemption — a separate legal route arguing the nitrogen load from this area is too small to warrant the upgrade requirement.

Because these are applications rather than granted permits, the suspension is conditional. A town that misses the milestones in its approved schedule can have the five-year upgrade clock started by MassDEP — running to 8 July 2030.

MassDEP's reports for this area

The studies behind this area, published by MassDEP. They cover the whole Great, Green, and Bournes Pond Embayment Systems area rather than Bournes Pond on its own.

Selling a property here

On the MassDEP nitrogen disclosure form, a seller in Bournes Pond would normally tick box 2 — located in a Nitrogen Sensitive Area, but not subject to the upgrade requirement because a filing covers the watershed — and name the filing for their town above.

Separately, a passing Title 5 inspection is required before transfer, as it is everywhere in Massachusetts. How the disclosure works →
