(1) When minimum requirement 8 applies pursuant to part 300 of this chapter and no exemption under SCC 30.63A.200 applies, and when a project will result in the direct or indirect (through a conveyance system) discharge of stormwater into a wetland or wetland buffer, the requirements of this section shall be met. Each threshold discharge area (TDA) within a project site that requires minimum requirement 8 must be reviewed to determine what level(s) of wetland protection must be applied to the TDA to comply with minimum requirement 8. Levels of wetland protection shall apply as set forth in volume I, Appendix I-D of the Drainage Manual.

(2) Stormwater treatment and flow control facilities shall not be built within a natural vegetated buffer, except as necessary for conveyance systems as approved by Snohomish County or as allowed in wetlands approved for hydrologic modification and/or treatment in accordance with volume I, chapter 2 and Appendix I-D of the Drainage Manual.

(3) In instances where stormwater from the project site discharges to a stream that leads to a wetland, or to a wetland that has an outflow to a stream, compliance with both minimum requirement 7 and minimum requirement 8 is required.
