17.135.080 Critical area report – Specific requirements for CARAs.
(1) A critical area report shall be required for any proposed use that is not permitted under SMC 17.135.060 or for any activity that is located within the one-year time of travel zone for any wellhead.
(2) An aquifer recharge area critical area report shall be prepared by a qualified professional who is a hydrogeologist, geologist, or engineer, who is licensed in the state of Washington and has experience in preparing hydrogeologic assessments.
(3) In addition to the requirements of SMC 17.114.160, a hydrogeological assessment shall be provided in a critical area report, and contain the following information:
(a) Available information regarding geologic and hydrogeologic characteristics of the site including the surface location of all critical aquifer recharge areas located on-site or immediately adjacent to the site, and permeability of the unsaturated zone;
(b) Groundwater depth, flow direction, and gradient based on available information;
(c) Currently available data on wells and springs within 1,300 feet of the project area;
(d) Location of other critical areas, including surface waters, within 1,300 feet of the project area;
(e) Available historic water quality data for the area to be affected by the proposed activity;
(f) Best management practices proposed to be utilized;
(g) Historic water quality data for the area to be affected by the proposed activity compiled for at least the previous five-year period;
(h) Groundwater monitoring plan provisions;
(i) Discussion of the effects of the proposed project on the groundwater quality and quantity, including:
(i) Predictive evaluation of groundwater withdrawal effects on nearby wells and surface water features; and
(ii) Predictive evaluation of contaminant transport based on potential releases to groundwater; and
(j) A spill plan that identifies equipment and/or structures that could fail, resulting in an impact. Spill plans shall include provisions for regular inspection, repair, and replacement of structures and equipment that could fail. (Ord. 1164 § 4, 2004).
