The purpose of the City of Saratoga Springs Zoning Ordinance is to encourage physical development while promoting public health, safety, and welfare. The ordinance is intended to classify, designate, and regulate the location and use of buildings, structures, and land for agricultural, residential, commercial, industrial, or other uses, and to divide the City into districts best suited to carry out the regulations set forth in the General City Law and provide for their enforcement. The regulations and district boundaries identified in the Zoning Map are also intended to facilitate the efficient and economical provision of public utilities, provide privacy and protection for families and residential areas, prevent traffic congestion, gradually eliminate nonconforming uses, conserve the value of land and buildings while enhancing the appearance of the City as a whole, encourage flexible design and development of land, protect natural resources, and safeguard the heritage of Saratoga Springs by promoting the use of historic districts and landmarks. Section 7.3.2 regulates certain activities to prevent pollution and manage storm water runoff during land development. A Storm Water Pollution Prevention Plan (SWPPP) is required for different land disturbance activities. Residential development (single and two-family development) activities involving land disturbance of 1.0-5.0 acres shall require a basic SWPPP; residential development activities involving land disturbance exceeding 5.0 acres shall require a full SWPPP; non-residential and mixed-use development exceeding 0.1 acre shall require the submission of a full SWPPP.
