construccion with a chain link or solid wooden fence a minimum of 4 feet high, or other fencing approved during the E•�iginaering and Public Scrvices plan review. (SEPA Earth and Water Policies) Surface/Groundwater, Plants and AnLnals No work is proposed within Merrill and Ring Creek or 'tt'� ouffer. The followi��g li�sl Management Practices (►3MPs) must be followed for all construction work adjacent to Mecritl and Ring Creek and its buffer, unless otherwise required by a permit issutd by a federal or state agency. Construction staging areas must be located outside of environmentally sensiti��e areas and their buffers, unless determined by the Planning Director to be infeasible. Streams, wetlands, buffers, staging areas and conswction limits shall be clearly shown on construction plans. Construction limits shall be clearly marked in the field with orange construction fencing. • Work shall be done so as to minimize turbidity, erosion, and other water quality impacts. Proper erosion and sediment control measures shall be followed to prevent sediments from entering creeks or wetlands. Erosion control measures shall be approved by the Deparunent of Engineering and Public Services and/or agencies with jurisdiction. Measures may includ" but not be limited to, placing silt fences and hay bales between construction areas and all adjacent wetlands and streams; and placing ecology blocks between construction areas and streams or wetlands when a temporary fill is used for roads, etc. • Erosion control measures shall be in place and inspected prior to commencement of work. All erosion control structures shall be inspected regularly to ensure they are maintained in working order. When operating machinery in or near water, extreme care shall be taken to prevent any petroleum products, cement, chemicals, or other toxic or deleterious materials from entering the water. If a spill dces occur, �vork shall be stopped immediately and Ecology's Spill Response Section contacted. • Equipment maintenance shall not occur in or adjacent to wetlands and streams. A variety of native species can be planteJ ro increase lceal diversity and provide attractive wildlife habitat while couniering erosion. The use of native plants can also improve water quality by minimizing the use of fertiliurs, herbicides, and pesticides. Water use efficiency is another advantage of landscaping with native plants. Reduced irrigation means reduced likelihood of erosion, siltation, and landsliding resulting from
