Fall 2022 Update: 

We are so happy to share that we closed on the “Deep Hole Creek” parcel at 4180 New Suffolk Avenue in Mattituck at the end of June! The Peconic Land Trust is now the interim owner of this property, which has been protected in perpetuity through the simultaneous sale of development rights by the Town of Southold.

We are so grateful to the Koehler family for choosing to collaborate with us, the Town, and YOU, the community, to achieve a conservation outcome. This land will be conserved forever, because so many people cared and joined together in community-focused spirit.

To preserve these 15 acres, once at risk of being subdivided into seven building lots, the Trust came forward as the temporary owner of the property. We will keep you posted in the weeks and months ahead as we steward this land as its interim owner and, importantly, as we seek to find a qualified conservation buyer to acquire the protected property and care for it in the future.

This conservation success story is an incredible outcome in a very short period of time, and is only possible because of community members who have energetically rallied to preserve this land. So far, over $652,000 in donations from community members has been raised toward the purchase and permanent protection of this farmland!

We are so grateful for your continued support and for the amazing progress we continue to make, together.

In late August, donors, community partners, and elected officials gathered at McCall Wines together in celebration of the community’s success in saving the Deep Hole Creek parcel and protecting it forever. By saving this small piece of farmland, this community has made a lasting difference in what the North Fork looks like – now and for future generations. We are so grateful for all you have done to make this project possible!

Visitor Information

The Deep Hole Creek parcel is viewable from New Suffolk Avenue and Marratooka Road in Mattituck. Since this parcel is expected to continue to be privately held and potentially cultivated, there is no public access.

There is, however, great public benefit from the protection of this land by contributing to the water quality and scenic vista of this area. We welcome your participation in this community fundraising project through consideration of a donation to support this acquisition, or by sharing our website with friends and neighbors to increase awareness. Thank you!
