Design standards

In addition, in reviewing proposed developments not exempt under section 32-138 of this ordinance, the planning board shall determine, taking into full consideration the report of the conservation commission, that the proposed use or development will not cause, or does not have the potential to cause, short or long term degradation to the water quality of the Kickemuit Reservoir with respect to established pollutant standards.

The planning board shall also review the site plan to insure that the proposed development adheres to the following performance and design standards where applicable:

- A. All new structures and expansions, paved areas and land disturbances shall be designed so as to minimize or prevent the discharge of any material which may have an adverse impact on the water quality of the reservoir.
- B. The storage of hazardous materials and petroleum products shall be located within a building unless it is determined that indoor storage will not meet fire safety standards. No new underground storage tanks shall be permitted.
- C. The exterior storage of hazardous materials and petroleum products contained within any tank larger than two hundred and seventy-five (275) gallons shall be located within a containment structure that meets the following standards:
  - 1. The base and surrounding dike shall be impermeable and compatible with the material being contained.
  - 2. The containment structure shall be protected by a roof and adequate sides to prevent exposure to stormwater. It shall also be protected from vehicular accidents, vandalism, corrosion, leakage or spillage through the use of steel guardrails, secure fencing, concrete barriers or similar devices acceptable to the planning board.
- D. Dumpsters shall be covered or located within a roofed area and shall not have open drain holes.

In its review, the planning board may impose restrictions and conditions which, in its judgment, will safeguard the source of drinking water supply for the town and others.
