The purpose of the Watershed Protection District (WPD) is:

   (A)   To protect, preserve and maintain the quality and supply of groundwater and surface water upon which the residents of the town and others depend;

   (B)   To protect the quality and supply of water by regulating the use and development of land adjoining water courses or primary water recharge areas and to prevent uses of land detrimental thereto; and

   (C)   To protect the health, safety and general welfare of the public.

(Ord. passed 10-30-06)

   The Watershed Protection District is superimposed over any other zoning district established by this chapter. The regulations imposed by the WPD shall be considered to supersede the regulations of the underlying district. The Watershed Protection District is subdivided into two subdistricts, designated Zone 1 and Zone 2.

   (A)   Zone 1 is an area which is critical to the protection of surface and sub-surface water supplies and requires a high degree of protection from incompatible land uses.

   (B)   Zone 2 is the watershed area which is contributory to surface water runoff to the primary water bodies contained in Zone 1, and which drains into Zone 1 areas either though surface water runoff or groundwater movement.

(Ord. passed 10-30-06)

   (A)   Areas within Zone l of the WPD are as follows:

      (1)   Areas shown on the official zoning map as that area within 200 feet from the centerline of a watercourse or the edge or bank of a surface water body or as otherwise shown on the official zoning map; and

      (2)   Those areas of Stissing silt loam (Se) as generally designated on Soil Survey of Rhode Island, U.S. Dept. of Agriculture, Soil Conservation Service, issued July 1981, the provision of which are incorporated herein by reference thereto; and

      (3)   Those areas of Mansfield mucky silt loam (Ma) as generally designated on said Soil Survey of Rhode Island, referenced in division (A)(2) above.

   (B)   NOTE: Recognizing that the standards employed in making said Soil Survey of Rhode Island allow for inclusion of small areas of contrasting soils, said soil survey map may be superseded provided the applicant provides adequate soil description information to the Zoning Board of Review. Such detailed soils information should be prepared by a qualified soil scientist and be presented using the descriptive terminology defined in the National Cooperative Soil Survey.

(Ord. passed 10-30-06)

   (A)   Buildings, structures and land in Zone 1 may be used only for the following purposes:

      (1)   Conservation of soil, water, plants, and wildlife;

      (2)   Water supply facilities and accessory uses and structures;

      (4)   Public streets or highways;

      (5)   Public or private parks;

      (6)   Uses customarily accessory to residential uses;

      (7)   Stormwater detention and/or retention areas or systems.

   (B)   Uses listed in divisions (A)(1) through (7) above are permitted in Zone 1 areas by right. All other uses otherwise permitted by right (Y) or by special use (S) in § 602, on lands within Zone 1 of the Watershed Protection District shall be permitted only by the granting of a special use permit by the Zoning Board of Review in accordance with the provisions of Article 9 and § 1106.

(Ord. passed 10-30-06)

   Areas within Zone 2 of the WPD are shown on the official zoning map.

(Ord. passed 10-30-06)

   (A)   This section is applicable to the following uses:

      (1)   Uses within Zone l otherwise permitted in the underlying zoning district (S or Y) pursuant to § 602. Uses listed in § 1103(A)(1) through (7) are permitted by right and are not governed by the provisions of this section.

      (2)   Uses in Zone 2 listed in § 1105(A) through (J)(4).

   (B)   Special use permits for these uses shall be granted by the Zoning Board of Review only if the Board determines that said proposed use would not be inimical to the public health, safety and welfare and that such use would not conflict with the purposes for which the WPD has been established. The Zoning Board of Review shall not act upon the granting of a special use permit until the question has been referred to, and an advisory report has been received from, the Planning Board and the Conservation Commission. Said advisory report shall be submitted by the Planning Board and Conservation Commission to the Zoning Board within 45 days of receipt of plans. The Zoning Board shall then hold a public hearing on the application for a special use permit. Where the decision of the Zoning Board of Review differs from the recommendations of the Planning Board or Conservation Commission, the reasons therefor shall be clearly stated in writing.

   (C)   Applications for special use permits in accordance with the provisions of this section shall meet all applicable requirements of Article 9, plus the requirements of § 1107.
