• Buffer nutrient reduction40 pct

  The 100-foot buffer area shall be deemed to achieve a seventy-five (75) percent reduction of sediments and a forty (40) percent reduction of nutrients.

• Buffer sediment reduction75 pct

  The 100-foot buffer area shall be deemed to achieve a seventy-five (75) percent reduction of sediments and a forty (40) percent reduction of nutrients.

• Buffer width100 ft

  a 100-foot buffer area of vegetation that is effective in retarding runoff, preventing erosion, and filtering non-point source pollution from runoff shall be retained if present and established during development where it does not exist.

• Minimum buffer width after encroachment50 ft

  In no case shall the reduced portion of the buffer area be less than fifty (50) feet in width and the encroachment may not extend into the seaward fifty (50) feet of the buffer area.

• Plan of development threshold2,500 sqftsq ftSquare feet. An acre is 43,560 sq ft; a typical suburban lot is 7,000–10,000.

  All development and redevelopment exceeding two thousand five hundred (2,500) square feet of land disturbance shall be subject to a plan of development process

• WQIA threshold for development size50 acresacre43,560 square feet — about the size of an American football field without the end zones.

  A WQIA is required for any proposed development or redevelopment within an RPA, including any buffer area encroachment as provided for in Section 36.271 of this Article, and in any development in the RMA if: a. The proposed development exceeds fifty (50) acres; or b. The proposed development results in more than sixty (60) percent impervious cover on the lot or parcel being developed.

• WQIA threshold for imperviousImpervious coverageThe share of a lot covered by anything water cannot soak through — roofs, drives, patios. cover60 pct

  A WQIA is required for any proposed development or redevelopment within an RPA, including any buffer area encroachment as provided for in Section 36.271 of this Article, and in any development in the RMA if: a. The proposed development exceeds fifty (50) acres; or b. The proposed development results in more than sixty (60) percent impervious cover on the lot or parcel being developed.
