          "In the summer of 1917 the U.S. Army began building Camp Upton near present-day Upton to train New York-area draftees for World War I; the first 2,000 men arrived September 10, 1917 and the camp was declared complete on December 20, 1917, eventually training roughly 40,000 soldiers, including the 77th Division.[3] Sergeant Irving Berlin served at Camp Upton and wrote the all-soldier musical revue \"Yip, Yip, Yaphank\" based on his experience there.[3] The camp was reactivated in 1940 as an induction center and later converted to a convalescent and rehabilitation hospital beginning in September 1944.[3] The federal government then repurposed the site for peaceful atomic research: \"In January 1947, Brookhaven National Laboratory was born.\"[3]"

          "Brookhaven has been the named party in two of the Court of Appeals' most significant Long Island environmental-law decisions. In Matter of Citizens for an Orderly Energy Policy v. Cuomo, 78 N.Y.2d 398 (1991), the Court of Appeals rejected separation-of-powers and environmental-review challenges to Governor Mario Cuomo's 1989 settlement agreement authorizing the Long Island Power Authority to acquire and close the Shoreham nuclear power plant.[4] The following year, in Matter of Long Island Pine Barrens Society v. Planning Board of the Town of Brookhaven, 80 N.Y.2d 500 (1992), the Court considered whether the State Environmental Quality Review Act required a single cumulative environmental impact statement covering more than 200 separate development projects then proposed across the Central Pine Barrens. Writing for the Court, Judge Titone concluded that \"the statutory and regulatory criteria for mandatory cumulative impact statements cannot, and should not, be stretched to cover this unique problem,\" reversing the Appellate Division and allowing the individual project reviews to proceed separately.[5] The Legislature responded within a year: \"The New York State Legislature approved and Governor Mario Cuomo signed the Long Island Pine Barrens Protection Act into law in 1993,\" creating a roughly 106,000-acre Central Pine Barrens region across \"portions of eastern Brookhaven Town, southern Riverhead Town and western Southampton Town.\"[6]",
          "Like most New York municipalities, Brookhaven cannot be sued over a defective road or sidewalk unless it had prior written notice of the specific defect; the Town's own Code, Chapter 84, is titled \"Notice of Defective or Dangerous Conditions.\"[7] Appellate courts have repeatedly applied it: in Owen v. Town of Brookhaven, 281 A.D.2d 527 (2d Dept. 2001), the Appellate Division affirmed summary judgment for the Town because it \"was not provided with prior written notice of the allegedly defective condition which caused the plaintiff to fall,\" citing Town Law § 65-a and Town of Brookhaven Code § 84-1.[8] The rule has a well-established exception, however: in Mayer v. Town of Brookhaven, 266 A.D.2d 360 (2d Dept. 1999) — a case brought by a motorcyclist \"thrown off her motorcycle when it struck a pothole in a roadway maintained by\" the Town — the Appellate Division reinstated the suit, holding that \"no prior written notice is required where the locality created the defect or hazard through an affirmative act of negligence,\" and that evidence the Town had performed repair work at the exact accident site weeks before the crash raised a triable issue of fact.[9] The Town's Code separately establishes a Traffic Violations Bureau (Chapter 6) and an Appearance Tickets chapter (Chapter 5).[7]"
