Use of common access points shall <br />be required for abutting lots which have no other feasible means of access. Alteration <br />for the purpose of providing access shall be limited to the minimum number of stream <br />crossings required to permit reasonable access. Bridging may be required when <br />necessary to protect significant stream functions. If a culvert is allowed, the design and <br />installation must be approved by WDFW. <br />c. When the proposal results in significant restoration of functions to the stream segment <br />and the alteration is approved by the Washington Department of Fish and Wildlife. <br />3.

The planning director may, using the review process described in EMC Title 15, Local <br />Project Review Procedures, allow alteration or relocation of Type Np and Ns streams <br />under the following conditions. <br />i. Stream and buffer functions in the relocated/altered stream section must be equal to <br />or greater than the functions provided by the stream and buffer prior to <br />relocation/alteration. <br />ii. The equivalent base flood storage volume shall be maintained; <br />iii. There shall be no impact to local ground water; <br />iv. There shall be no increase in water velocity; <br />v. There is no interbasin transfer of water; <br />vi. The relocation shall occur on-site and shall not result in additional encumbrances on <br />neighboring properties unless necessary easements and waivers are obtained from <br />affected property owners; <br />vii.The relocation maintains or enhances existing connections to other critical areas and <br />Priority Habitats. <br />c.

Bridging may be required when <br />necessary to protect significant stream functions. If a culvert is allowed, the design and <br />installation must be approved by WDFW. <br />4. Watershed Management Plans. The city shall not allow relocation or alteration of any <br />Type F stream located within an area where an adopted watershed management plan <br />does not allow for stream alteration or relocation, except when allowed by Section 5 <br />(37.050) of this chapter, or to allow access to a lot or substantial portion of a lot when <br />no other feasible means of access exists. <br />45 <br />
