The Town Board of the Town of Islip finds that the Connetquot River, from its headwaters to the Great South Bay, is a unique recreational river area. The State of New York has designated a portion of this river, from its headwaters to Sunrise Highway, a recreational river, thereby ensuring the preservation and restoration of its natural scenic preservation and restoration of its natural scenic and recreational qualities. Although the State of New York has not included that portion of the river south of Sunrise Highway in its designation, the Town Board of the Town of Islip finds that this portion possesses remarkable beauty, remains relatively unspoiled by development and is an invaluable recreational facility. The preservation and restoration of the natural scenic and recreational qualities of this portion of the river is important. Upland and waterborne development which materially affects the existing condition, use or appearance of the river south of Sunrise Highway should only be permitted under regulations that will prevent adverse effects upon its scenic and recreational qualities.
