f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. <br /> No erosion will occur. <br /> a. About what percent of the site will be covered with impervious surfaces after project <br /> construction (for example, asphalt or buildings)? No impervious surfaces are being added <br /> to the site as a result of this project <br /> a. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: No <br /> erosion will occur. <br /> 2. Air <br /> a. What types of emissions to the air would result from the proposal during construction_ <br /> operation, and maintenance when the project is completed? If any, generally describe and <br /> give approximate quantities if known. Minor diesel emission may occur while work is <br /> being done- total time to complete proposed work would be less than three days. <br /> b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, <br /> generally describe. None <br /> c. Proposed measures to reduce or control emissions or other impacts to air, if any: The <br /> proposed project is in an open area-any emissions would disipate quickly. <br /> 3. Water <br /> a. Surface Water: <br /> 1. Is there any surface water body on or in the immediate vicinity of the site (including <br /> year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe <br /> type and provide names. If appropriate, state what stream or river it flows into. The <br /> project is adjacent to the Snohomish River <br /> 2) Will the project require any work over, in, or adjacent to (within 200 feet)the described <br /> waters? If yes, please describe and attach available plans. Yes-the proposed work is <br /> for the elimination of 875 cubic yards of silk in the existing boat launch ramps. <br /> Work would occur during minus tides using a long reach excavator placing the silt <br /> into dump trucks to be hauled off site. <br /> 3) Estimate the amount of fill and dredge material that would be placed in or removed <br /> from surface water or wetlands and indicate the area of the site that would be affected. <br /> Indicate the source of fill material. No fill is required- the excavated material would be <br /> be hauled off site with placement on two possible sites- Cedar Grove, which is <br /> /S <br />
