The detention pond, constructed in 1997 when the property was owned by the Boeing Company, is in need of sediment removal and general maintenance and upgrading. The pond was constructed to prevent downstream transfer of upstream sediment and limit downstream flow during periods of high stream flows. The maintenance and upgrade components of the project are also necessary for the protection of the newly restored salmon habitat further downstream on Sabey property. The project is located in the Manufacturing / Industrial Center / Light zone (MIC /L) and, as such, is eligible for a SEPA Planned Action. The applicant received the input and assistance of Ryan Partee, Department of Public Works Fisheries Biologist, for the consideration of project impacts on the on -going salmon habitat restoration efforts. Agencies with Jurisdiction: Washington Department of Fish and Wildlife. Recommendation: Determine that the proposed sediment pond maintenance and improvements fall under the planned action criteria and therefore require no additional SEPA review. • • CITY OF TUKWILA CrrYOF TUKWILA Department of Community Development 6300 Southcenter Boulevard, Tukwila, WA 498882 0 2002 Telephone: (206) 431 -3670 FAX (206) 431;1665 E-mail: E -mail: tukplan @ci.tukwila.wa.us RECEIVED CITY OF TUKWILA SEPAN 2 0 2002 PLANNENTER ACTION APPLICATION FOR STAFF USE UNLY Sierra Type: P -PACT Planner: File Number: t OD- -o Kp Application Complete: (Date: Project File Number: Application Incomplete: (Date: MIC Planned Action EIS File Number: E96 -0034 Other File Number: NAME OF PROJECT/DEVELOPMENT: �C�P2.��1 -.`� -, Pw-.64 ,A' v4 Cif con O LOCATION OF PROJECT/DEVELOPMENT: Give street address or, if vacant, indicate lot(s), block and subdivision, access street, and nearest intersection.

Most projects that involve grading have the potential to result in increased erosion and/or sedimentation as a.result of disturbances to the soil or earth. If your project involves grading and you have not prepared a, Temporary Erosion and Sedimentation ContgaLP4an specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. NO - Continue to Question 1 -3 1 -3 ill the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -12). Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development.

This action is not anticipated to have a direct effect on salmonids and is not anticipated to result in take as a result of direct affects. (Note: Indirect impacts are evaluated separately.) 2 Habitats in these watercourses or rivers are either directly used by salmonids or support pathway- indicator relationships that are critical for salmonids. Actions effecting these habitats may result in the take of a salmonid. 3 All projects in the City ultimately drain to salmonid- bearing waters. The results of these actions may result in significant secondary alteration to receiving waters that may support salmonid use. Significant secondary effect to these areas may result in the take of salmonids using habitats in these areas. 4 All projects in the City ultimately drain to salmonid - bearing waters. The results of these actions are not anticipated to result in a significant change in the receiving bodies or they may result in a change but are not anticipated to result in an affect to salmonids or a critical habitat element.
