PART "B": Riparian Restoration This residential development project could contain riparian restoration components as the phasing continues pursuant to the development build out. Currently the first proposed bridge (over EWC canal) to be installed contains an encroachment into an Identified Category IV wetland. The square footage of this encroachment will be calculated with the appropriate replacement ratio used per the Kittitas County Critical Areas Code (KCC) 17.A.04, with the replacement area along Currier Creek identified. Riparian re -vegetation actions along Currier Creels will require an irrigation system to establish plants in the near-term. The bridge encroaches into an identified Category IV wetland on the eastern side of EWC canal. The bridge abutment, on the south side of the road, encroaches into the Category IV wetland 800 square feet. The 800 square feet includes an additional 15 -foot buffer from the boundary edge of the wetland. Pursuant to KCC 17A.04.040 up to 2 acres of Class IV wetlands may be filled, drained, or modified with no approval from the planning manager. Furthermore KCC 17A.04.050 still requires a replacement ratio for disturbed wetlands. The landowner will be disturbing 800 Sq. ft. of a Category IV wetland due to a single bridge abutment. The landowner is proposing a replacement area along Currier Creek. The replacement ratio of 2:1 will be used and is more than the county code requires for a Category IV wetland. This will result in a1600 square feet replacement area along Currier Creek. Native riparian plants will be used. See Exhibit C. Bridge drawing and restoration location. The re -vegetation will be of like kind native riparian vegetation. PART "C": Establish a 200 -foot buffer zone along Currier Creek. Develop an assessment of habitat improvement opportunities and non -diversionary irrigation water efficiencies. This project component will require a 100 -foot buffer from the top bank line of Currier Creek on both sides (See Exhibit D). As part of this plan the landowner will include the development of a piping strategy that will allow irrigation water (Ellensburg Water Company) to be delivered in an efficient system of pipes rather than through the creeks. This piping strategy will require a irrigation plan, using the landowners water rights, showing how irrigation water will be provided to each lot has the development continues to build out. This strategy eventually eliminates the use of flood irrigation and creating more efficient irrigation system therefore providing more water and protection to the Currier Creek. PART "D": Future habitat improvements and\or irrigation efficiencies. The Landowner is willing to continue to review Currier Creek riparian areas throughout the life of the project along with entertaining other agency proposals for future habitat or irrigation improvements that would be beneficial to Currier Creek. The landowner will also allow the continuation of access through the property for the transplanting of fish into the Currier Creek tributary. Page 2 of 4
