• Earthwork. The project will require earthwork above and below the OHWM.The majority of the project's <br /> earthwork will consist of excavating the roadway embankment over the existing culverts.Excavation,grading and <br /> limited bacicfill will be necessary to construct culvert footings,the stream channel and new roadway embankments <br /> after removing the existing culverts and headwall.Approximately 237 cubic yards of Class A riprap will be removed <br /> and replaced on the banks,4-inch cobbles and streambed sediment will be placed to a depth of 2-feet throughout the <br /> restored stream channel to enhance channel stability. Streambed gravel sizing and distribution will be in accordance <br /> with WSDOT Standard Specification 9-03.11 (WSDOT 2016). <br /> • Road Construction.The roadway will be finished with hot-mix asphalt and gravel base course <br /> and guard rails will be added. <br /> • Mitigation and Restoration Activities.All temporary construction impacts will be restored <br /> following completion of construction activities.During construction,some of the native vegetation within <br /> the disturbance area will be salvaged as possible,for replanting.Disturbed areas that were vegetated will <br /> be re-planted with native plants that are currently found within the area.The City is proposing to overplant <br /> the area in order to account for potential plant mortality and to create vegetated cover more quickly. <br /> See the attached Critical Areas Assessment Report and Restoration Plan for details on species,density, <br /> estimated quantities and proposed restoration areas. <br /> 12. Location of the proposal. Give sufficient information for a person to understand the precise <br /> location of your proposed project, including a street address, if any, and section, township, and <br /> range, if known. If a proposal would occur over a range of area, provide the range or <br /> boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic <br /> map, if reasonably available. While you should submit any plans required by the agency, you <br /> are not required to duplicate maps or detailed plans submitted with any permit applications <br /> related to this checklist.
