  For any commercial or industrial development which creates five acres or more of impervious surface, or any subdivision which creates 50 or more lots, a resource quality protection plan must be submitted and approved.

• Design standards

  Release rate and pollutant loading of stormwater runoff shall not exceed predevelopment; channeling runoff directly into water bodies prohibited; banks of detention areas slope 3:1 or less; preserve intermittent watercourses in vegetated condition; use approved stormwater management practices.

• Groundwater use analysis threshold

  A groundwater use analysis shall be included in the resource quality protection plan for any proposed subdivision with 50 or more lots and an expected groundwater use of 10,000 gallons per day or more.

• Performance criteria

  Minimize disturbance of existing soils and retain vegetation; minimize impervious cover; maintain buffer strips of natural vegetation along water bodies; avoid siting facilities on wetlands; minimize crossing of watercourses; minimize well water impact; obtain all permits.
