Farmland in Sussex County, NJ: Dairy and the Highlands Ridge

Sussex County has been formally recognized by New Jersey's own state planning process as a location of excellent agricultural and natural resource lands. Here's what its dairy, hay, and corn farming economy, and its Highlands-adjacent geography, mean for a farmland buyer.

This page covers what's specific to Sussex County. For the general explanation, see the national guide.

A state-recognized agricultural resource area centered on dairy

Sussex County's agricultural economy is built primarily on hay, corn, dairy, and horticulture, and both the State Development and Redevelopment Plan and the Highlands Regional Master Plan formally recognize the county as a location of excellent agricultural and natural resource lands. That recognition isn't incidental -- most of the county's best farmland sits along or near the Highlands Ridge running between Vernon and Byram Townships, and near the Kittatinny Ridge close to the county's northern border, geography that has kept large-scale suburban development from displacing agricultural use the way it has in much of central and southern New Jersey.

Dairy in particular holds a historically central place in Sussex County's farm economy, though the county's own planning documents are candid that sustaining dairy's dominance requires a concerted, ongoing effort -- language that reflects the same economic pressures (commodity milk pricing, land costs, generational farm transitions) affecting dairy operations nationally, rather than suggesting dairy has already disappeared from the county. A buyer specifically interested in an active or former dairy operation should ask directly about a parcel's current agricultural use and any recent history of dairy operations, since the underlying land -- barns, silos, and pasture infrastructure -- can still carry real value and specific zoning classifications even where active dairying has scaled back.

The farmland preservation program: a real but imprecisely current total

The Sussex County Agriculture Development Board (SCADB) administers the county's farmland preservation program in partnership with the state's Agriculture Development Committee (SADC), working with municipalities and nonprofit organizations to identify and preserve qualifying farms. As of the end of 2007, the county's own planning documents put the total preserved acreage at 12,362 acres -- a genuinely substantial figure for the time, though clearly a dated one nearly two decades old at this writing. This page also found a separate, differently scoped figure describing 2,763 acres across 26 farms in 6 municipalities, which could not be reconciled with the 12,362-acre total in this research pass; it may reflect a specific sub-program, funding round, or different reporting period rather than a contradiction. Given that ambiguity, treat both figures as historical reference points and confirm the SCADB's current total directly rather than relying on either number as up to date.

As with any New Jersey county farmland preservation program, an enrolled farm carries a recorded conservation easement that runs with the land regardless of ownership, permanently restricting non-agricultural development while preserving the ability to farm, sell, and finance the property. A buyer evaluating a preserved Sussex County farm should request the specific easement terms from the SCADB directly, since the exact permitted uses (secondary residences, agritourism activity, farm-worker housing) can vary somewhat farm to farm.

What to check before buying farmland in Sussex County

First, confirm with the SCADB whether a specific parcel is currently enrolled in the preservation program and, if not, whether the board is accepting new applications -- program funding availability changes over time. Second, if the parcel sits near the Highlands Ridge or Kittatinny Ridge, separately confirm with the New Jersey Highlands Council whether it falls within the mapped Highlands Region and, if so, whether it's in the Preservation Area (subject to direct state regulatory standards) or the more locally governed Planning Area, since farmland inside the Preservation Area can face additional water-quality-driven restrictions beyond ordinary agricultural zoning.

Third, budget for Sussex County's specific soil conditions when evaluating septic feasibility for any residence or farm-worker housing on the property: the Sussex County Division of Health's Office of Environmental Health enforces the statewide N.J.A.C. 7:9A septic standard plus additional design requirements tailored to the clay-heavy soil conditions common in parts of the county, which can affect both perc-test outcomes and system design cost beyond the generic statewide baseline. A licensed local soil evaluator with specific Sussex County experience is worth engaging before finalizing a purchase decision that depends on septic feasibility.
