Southern Tier New York Government and Regional Planning

The Southern Tier is one of New York State's most geographically distinct economic regions, spanning a broad arc of counties along the Pennsylvania border from the Delaware River watershed in the east to the Lake Erie shore in the west. Regional planning in this zone involves a layered system of county governments, state agencies, and interstate compacts that coordinate land use, transportation, economic development, and environmental management. Understanding how authority is distributed across this region is essential for residents, businesses, and local officials navigating permits, infrastructure investment, and social services.

Definition and scope

The Southern Tier region, as formally recognized by the Empire State Development Corporation and the New York State Division of the Budget, encompasses 8 core counties: Broome, Chemung, Chenango, Delaware, Schuyler, Steuben, Tioga, and Tompkins. A broader definition used by the Southern Tier Regional Planning and Development Board also draws in Allegany and Cataraugus counties, which connect the Southern Tier corridor to Western New York regional government.

The region's geographic extent covers approximately 9,000 square miles, making it larger in land area than the states of Connecticut and Rhode Island combined. Population density across the region averages fewer than 100 persons per square mile in most non-urban counties, contrasting sharply with metropolitan areas like New York City or even the Capital Region.

Scope and coverage limitations: The Southern Tier regional planning framework applies to counties within the boundaries described above and to programs administered under New York State authority. It does not govern activity in Pennsylvania's Tier counties immediately to the south, does not extend to Finger Lakes counties (covered separately under Finger Lakes regional government), and does not apply to federally designated lands such as the Catskill-Delaware watershed protection areas, which fall under U.S. Environmental Protection Agency jurisdiction. Readers seeking information specific to Central New York governance should consult that region's dedicated reference.

How it works

Regional planning in the Southern Tier operates through three primary structural mechanisms:

County governments — Each of the 8 core counties maintains an elected legislature (or board of supervisors) that passes local laws, adopts budgets, and administers state-mandated programs including social services, public health, and real property assessment. Binghamton, located in Broome County, functions as the region's largest city and serves as the informal administrative hub.
Regional Planning and Development Boards — The Southern Tier Central Regional Planning and Development Board serves Chemung, Schuyler, and Steuben counties. A separate organization, the Southern Tier East Regional Planning Development Board, covers Broome, Chenango, Delaware, Otsego, and Tioga counties. These boards are public benefit corporations authorized under Article 12-B of the New York General Municipal Law, enabling them to prepare regional plans, administer federal grants, and provide technical assistance to member counties and municipalities.
State agency regional offices — The New York State Department of Transportation Region 9 office, based in Binghamton, manages federal and state highway programs across the Southern Tier. The New York State Department of Environmental Conservation Region 7 covers portions of the zone. These offices implement state policy but do not create it independently.

The New York State Regional Economic Development Councils, established by executive order in 2011, added a competitive grant layer to this structure. The Southern Tier Regional Economic Development Council submits annual strategic plans and competes for funding from the state's $750 million consolidated funding pool alongside 9 other regional councils (REDC Program, Empire State Development).

Common scenarios

The following situations routinely engage Southern Tier regional planning structures:

Infrastructure funding applications: A municipality seeking federal transportation dollars routes its request through the Southern Tier region's Metropolitan Planning Organization (MPO) or the regional planning board, which maintains the federally required Transportation Improvement Program list. Projects not appearing on this list are ineligible for federal-aid highway funding.
Economic development site selection: A manufacturer evaluating a site in Steuben County may interact with the county's Industrial Development Agency (IDA), the Southern Tier Central Planning Board for environmental review support, and Empire State Development for Excelsior Jobs Program tax credits simultaneously.
Agricultural land preservation: Farms in Chemung or Tioga counties seeking conservation easements work through the New York State Department of Agriculture and Markets Farmland Protection Program, often coordinated with county soil and water conservation districts.
Broadband expansion: Rural broadband projects in Delaware County apply through the New York State Broadband Program Office and coordinate with county planning departments on right-of-way and easement issues. Delaware County's geographic isolation — with roughly 47,000 residents distributed across 1,446 square miles — makes broadband investment a high-priority regional planning issue (U.S. Census Bureau, 2020 Decennial Census).

Decision boundaries

Authority in the Southern Tier is bounded by legal structure, not geography alone. Several distinctions define where one governmental layer's authority ends and another's begins.

County versus municipal jurisdiction: County land-use regulations apply only in unincorporated territory. A zoning ordinance adopted by Broome County does not supersede the City of Binghamton's zoning code within Binghamton's municipal limits. Cities, villages, and towns retain independent zoning authority under New York's Municipal Home Rule Law (New York Municipal Home Rule Law, §10).

Regional planning boards versus county legislatures: Planning and development boards carry no direct regulatory authority. They prepare plans, administer grants, and provide technical assistance — they do not pass ordinances or levy taxes. A regional plan recommendation carries persuasive weight but requires adoption by individual county or municipal governments to become binding.

State agency authority versus local discretion: When a state agency such as the Department of Environmental Conservation issues a permit or enforcement order, local governments cannot override or nullify that determination. The reverse also applies: a county health department may impose standards stricter than state minimums for certain programs but cannot relax state-set floors. This distinction matters most in environmental permitting, where Southern Tier New York government stakeholders often encounter overlapping DEC, Army Corps of Engineers, and county-level review for projects near waterways.

Interstate compacts and federal preemption: The Delaware River Basin Commission (DRBC), a federal-interstate compact body with authority over the Delaware River watershed, exercises jurisdiction that preempts both state and local authority within its defined basin area. Counties in the eastern Southern Tier — particularly Delaware and Chenango — fall partly within this zone. The DRBC's water withdrawal and natural resource regulations apply regardless of New York State or county action.
