vi. The relocation shall occur on-site and shall not result in additional encumbrances on neighboring properties unless necessary easements and waivers are obtained from affected property owners; vii.The relocation maintains or enhances existing connections to other critical areas and priority habitats. c. Stream Crossings. Stream crossings are regulated by the Washington State Department of Fish and Wildlife (WDFW).Stream crossings shall only be permitted as provided by Section 19.37.050 of this chapter or to provide access to a lot or a substantial portion of a lot when no other feasible means of access exists. Use of common access points shall be required for abutting lots which have no other feasible means of access. Alteration for the purpose of providing access shall be limited to the minimum number of stream crossings required to permit reasonable access. Bridging may be required when necessary to protect significant stream functions. If a culvert is allowed,the design and installation must be approved by WDFW. 4. Watershed Management Plans.The city shall not allow relocation or alteration of any Type F stream located within an area where an adopted watershed management plan does not allow for stream alteration or relocation, except when allowed by Section 19.37.050 of this chapter, or to allow access to a lot or substantial portion of a lot when no other feasible means of access exists. CB. Compensating for Stream Impacts. Stream system and buffer alteration,when allowed by this chapter, shall be subject to the following requirements: 1. Each activity/use shall be designed so as to minimize overall stream system or buffer alteration to the greatest extent possible. 2. Construction techniques and field marking of areas to be disturbed shall be approved by the city prior to site disturbance to ensure minimal encroachment. 3. A mitigation plan shall be prepared in accordance with this section. 4. The city may require the applicant to rehabilitate a stream system and its buffer area by removing harmful debris, sediment, nonnative vegetation, or other material detrimental to the area, by replanting disturbed vegetation, by removing tightlined or culverted portions of a stream from pipes/culverts, or by other means deemed appropriate by the city. Rehabilitation or restoration may be required at any time that a condition detrimental to stream functions exists. 5. In approving alteration or relocation of a stream system or its buffer,the city may require that an area larger than the altered portion of the stream and its buffer be provided as compensation for destruction of the functions of the altered stream system and to ensure that such functions are replaced. 6. When stream system relocation or compensation is allowed,the city shall require that the stream relocation be completed prior to allowing the existing stream to be filled or altered. 7. The city may limit certain development activities near a stream to specific months in order to minimize impacts on water quality and wildlife habitat. 8. The city may apply additional conditions or restrictions, or require specific construction techniques in order to minimize impacts to stream systems and their buffers. 9. Stream compensation shall not occur in areas having high-quality terrestrial habitat. CB.Voluntary daylighting of streams in pipes and culverts. 1. To encourage daylighting of streams in pipes and culverts,the planning director may modify development standards as set out in subsection D.2 of this section when the applicant submits a plan for daylighting that meets the following criteria: a. The plan is prepared by a qualified professional; b. The ecological functions of the daylighted waters and adjacent area are improved so the new riparian corridor is compatible with and protects the ecological functions of the existing EMC Title 19.37 (Critical Areas) Page 50
