Contents of environmental review statement
a. The environmental review statement shall contain appropriate and sufficient data to determine the probable effect of the proposed development on the water supply resource. In compiling such statement, the applicant shall consult with the various town departments, such as the department of public works, conservation commission, etc., having knowledge and authority in the various subjects cited below. The ERS shall include, where applicable, an analysis of local, state and federal performance standards as they relate to the proposed project. The specific scope of each ERS shall be determined by the planning board based on the particular circumstances of each application.
b. The planning board shall have the power to require an applicant to submit additional documentation in support of its application, where the planning board believes that such information is necessary in determining the impact of the proposal. The ERS shall be analytical rather than encyclopedic, and must, at a minimum, contain the following:
(1) A concise description of the proposed project including its use, purpose, need, total land area and total area of proposed development, and proposed phasing.
(2) A concise description of the environmental setting of the project and the area to be impacted, to include all manmade, natural and physiographic features within 500 feet of the property line. This shall include, but not be limited to, wetlands or water bodies, soils, topography, vegetation, unique species and habitat areas and existing development. The use of mapped data is encouraged. Data must be sufficient so that the effects of and alternatives to the proposed project can be understood.
(3) A wetlands permit or a finding of no significant impact (FONSI) from the department of environmental management (DEM), where applicable.
(4) Approval for an OSDS upgrade from the DEM, where applicable.
(5) A complete list of all chemicals, pesticides, fertilizers, fuels and other hazardous materials to be used or stored on the premises in quantities substantially greater than those associated with normal household use. This list shall be accompanied by a description of the measures to protect them from vandalism, corrosion, and leakage and to provide for spill prevention and countermeasures.
(6) A description of potentially hazardous wastes to be generated, indicating a storage and disposal method.
(7) A statement of any prior or anticipated flood levels, and of the expected flood hazard present on the site.
(8) An erosion and sediment control plan.
(9) A plan for stormwater management.
(10) A statement of both the favorable and adverse environmental impacts of the proposed project, including short and long term effects, on-site and off-site impacts and the cumulative impact of the proposed project as it relates to the entire watershed. Such discussion must include nutrient loading, point and non-point-source water quality impacts to surface and ground waters, applicable data on wetlands and identification of significant habitats impacted by the project.
(11) A discussion and evaluation of the alternatives considered in the design and location of the project.
(12) The identification of any irreversible commitment, or alteration of natural features as a result of the proposed action.
(13) The means and estimated costs necessary to minimize adverse environmental impacts.
(14) A list of any underlying studies, reports and other information obtained and considered in preparing the ERS.
c. Drawing standards and documentation requirements for building permit requests within the Watershed Protection Overlay Districts are contained in the written procedures of the Tiverton Planning Board. In addition, as described in these procedures, a corporate survey is required for any application that involves one of multiple or shareholder parties leasing land within the Stafford Pond watershed. This corporate survey, minimum class IV, must be on file in the office of the building official one year from zoning ordinance amendments effective June 4, 2001, and must indicate all structures, roadways and overall area of the corporate or multiple leased area.
d. In reviewing the appropriateness of the development for a Watershed Protection Overlay District, the planning board shall give consideration to the simplicity, reliability and feasibility of the control measure proposed, and the degree of threat to water quality and/or quantity which would result if the control measures were to fail. In its review, the planning board may impose restrictions and conditions which in its judgment will safeguard the source of water supply for the town, upon finding that the issuance of said permit will not adversely effect said source of water supply.
