Yes the project will alter the drainage pattern for the site. Currently, during high flow events, <br /> the creek overtops the roadway and has caused erosion and endangered the roadway stability. <br /> The proposed project will replace the culvert with a larger structure that is designed to be fish <br /> passable and accommodate high flow events. <br /> d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage <br /> pattern impacts, if any: 'help' <br /> Stormwater generated during active construction will be managed using BMPs. <br /> 4.

However,other species that will be removed include grasses,Himalayan blackberry,vine <br /> maple,thimblebeny,red alder trees and bigleaf maple trees(See figure 2 in the Critical Areas Assessment <br /> and Restoration Plan).Approximately 4,820 square feet of herbaceous vegetation,2,090 square feet of <br /> Himalayan blackberry, 1,345 square feet of native shrub vegetation and a total of eight red alder trees <br /> (approximately 7 to 9-inch diameter at breast height)and three big leaf maple trees(approximately 7 to <br /> 12-inch diameter at breast height)will be removed.A total of 3,200 square feet of existing riprap <br /> armoring will be replaced in approximately the same location. Some native shrubs are currently growing <br /> within the existing riprap area. <br /> c. List threatened and endangered species known to be on or near the site. 'help"' <br /> There are no known threatened or endangered plant species that are known to be on or near the site. <br /> d.
