Greene Group Construction Corp — 24/7 emergency water damage restoration, fire damage restoration, mold remediation, and roofing in Riverhead, Suffolk County, Long Island.
Riverhead is a hamlet and the county seat of Suffolk County, with a population of about 13,299 as of the 2010 Census (the hamlet corresponds to the Riverhead CDP within the Town of Riverhead). Situated at the mouth of the Peconic River where it empties into Peconic Bay, Riverhead has served as county seat since 1727, though most county offices later moved to Hauppauge.
Downtown Riverhead sits along the Peconic River, marking the split between Long Island's North and South Forks. The hamlet's historic role as Suffolk County's administrative center is reflected in its downtown civic buildings.
Riverhead's housing includes historic homes near the Peconic River waterfront alongside more typical suburban construction further inland. Waterfront and near-river properties face significantly higher flood exposure than the hamlet's interior.
With direct frontage on the Peconic River where it meets Peconic Bay, Riverhead carries real storm-surge and tidal flood risk for its waterfront and downtown-adjacent neighborhoods.
