Summary
Clarkstown's Architectural Historic Review Board (AHRB) sets the criteria for identifying historic, architectural and cultural landmarks and must review any building or sign permit affecting a Town-designated historic site or district outside the villages. Owners who let a designated property deteriorate face separate violations and escalating fines under § 5-18.
E. To adopt criteria for the identification of historic, architectural and cultural landmarks within the Town; F. To give advisory recommendations to the Town Board for the designation of historic landmarks, sites, roads and districts in the Town of Clarkstown for potential elevation to regional, state or national prominence;
Full Breakdown
The Town Board created the seven-member Architectural Historic Review Board under § 5-2, including a Chairperson and Vice Chairperson, with members trained in art, architecture, tree preservation, landscaping or historical preservation serving staggered seven-year terms. Section 5-3 gives the AHRB authority to adopt criteria for identifying historic, architectural and cultural landmarks within the Town (§ 5-3E) and to give the Town Board advisory recommendations for designating historic landmarks, sites, roads and districts for potential elevation to regional, state or national prominence (§ 5-3F), plus recommendations on using state, federal or private grant funds to preserve those landmarks (§ 5-3G).
Once a property is designated, § 5-4A requires the Building Inspector to refer any building or sign permit application affecting a historically designated residential structure, or any site within a designated historical area, to the AHRB before a permit can issue; the Board has 45 days to act, and inaction within that window counts as automatic approval. Under § 5-5, ordinary maintenance that does not change design, material, color or outward appearance needs no AHRB review, but an owner may not let a designated historic site or a property within a historic district fall into disrepair that damages exterior architectural features, listing deterioration of walls, columns, roofs, soffits, siding and chimneys as examples.
Decisions can be appealed to the Zoning Board of Appeals within 30 days under § 5-6. This authority runs only in the Town of Clarkstown outside the incorporated areas; it does not reach the Villages of Nyack, Upper Nyack or South Nyack, each of which runs its own separate historic-preservation code.
Violations & Fines
First-offense fines run up to $2,500; a second offense within 18 months costs $2,500 to $5,000; a third costs $7,500 to $10,000; and a fourth or subsequent offense within 18 months costs $10,000 to $15,000, with every week of continued noncompliance a separate offense. Owners who let a designated historic site deteriorate must restore it to AHRB-acceptable condition, enforceable by the Town Attorney as a civil remedy alongside criminal prosecution by Code Enforcement.
