Greene Group Construction Corp — 24/7 emergency water damage restoration, fire damage restoration, mold remediation, and roofing in Locust Valley, Nassau County, Long Island.
Locust Valley is a hamlet on the North Shore of Long Island in the Town of Oyster Bay, Nassau County, with a population of about 3,485 as of the 2020 Census. Originally called Buckram after Captain John Underhill purchased the land from the Matinecock in 1667, the hamlet was renamed Locust Valley in 1856 for its abundant locust trees.
Locust Valley became part of the North Shore's "Gold Coast" in the early 1900s, with wealthy families building great estates nearby. The Matinecock Friends Meetinghouse and Planting Fields Arboretum are notable historic and cultural landmarks near the hamlet.
Locust Valley's housing includes historic estate-era homes alongside a commercial center that grew up around its 1869 railroad station. Older homes carry original plumbing and roofing systems common to the Gold Coast era.
Locust Valley sits at about 128 feet of elevation on the North Shore with limited direct waterfront, though its proximity to Long Island Sound means rising sea levels and storm intensity are increasing flood risk — an estimated 165 properties face moderate flood risk over the next 30 years.
