Agricultural districts and preservation
Delaware's Agricultural Lands Preservation programme operates in two stages. A landowner can enroll land in an agricultural district for a ten-year term, receiving tax benefits and protections. Districts can then be offered for permanent preservation easement purchase by the state.
A buyer acquiring enrolled land inherits the commitment. Establish which stage applies, when the term expires, and whether a permanent easement has been sold — the last of these is irreversible.
County zoning differs meaningfully
Delaware's three counties administer zoning independently and with different philosophies. Sussex County's approach to rural residential development, minimum lot sizes and agricultural protection differs from Kent's and New Castle's, and the differences matter for what a parcel can become.
Direct every buildability question to the specific county, and expect the answer to differ from what a neighbour across the county line experienced.
Growth pressure and price
Coastal Sussex has experienced substantial residential development, and agricultural land within reach of the growth corridors is priced with development potential in mind. Land further inland trades closer to agricultural value.
A buyer should be clear which they are purchasing, because agricultural returns do not support development-premium prices.
Wetlands and drainage
Delaware's low elevation means wetlands and drainage matter across much of the state. State and federal wetland jurisdiction both apply, and tax ditch systems administered locally assess benefited land for drainage maintenance.
What to verify
Agricultural district enrollment or permanent easement status. County zoning and what it permits. Tax ditch assessments. Wetland delineation where building is intended. Septic feasibility, which matters given water table depth. The risk scorecard covers the screening.
