Exhibit B <br />ORDINANCE Exhibit A - Page 65 of 66 <br />for stream alteration or relocation, except when allowed by EMC 19.37.050, or to allow access <br />to a lot or substantial portion of a lot when no other feasible means of access exists. <br />B. Compensating for Stream Impacts. Stream system and buffer alteration, when allowed by this <br />chapter, shall be subject to the following requirements: <br />1. Each activity/use shall be designed so as to minimize overall stream system or buffer <br />alteration to the greatest extent possible. <br />2. Construction techniques and field marking of areas to be disturbed shall be approved by the <br />city prior to site disturbance to ensure minimal encroachment. <br />3. A mitigation plan shall be prepared in accordance with this section. <br />4. The city may require the applicant to rehabilitate a stream system and its buffer area by <br />removing harmful debris, sediment, nonnative vegetation, or other material detrimental to the <br />area, by replanting disturbed vegetation, by removing tightlined or culverted portions of a <br />stream from pipes/culverts, or by other means deemed appropriate by the city. Rehabilitation <br />or restoration may be required at any time that a condition detrimental to stream functions <br />exists. <br />5. In approving alteration or relocation of a stream system or its buffer, the city may require <br />that an area larger than the altered portion of the stream and its buffer be provided as <br />compensatory mitigation for destruction of the functions of the altered stream system and to <br />ensure that such functions are replaced. <br />6. When stream system relocation or compensatory mitigation is allowed, the city shall require <br />that the stream relocation be completed prior to allowing the existing stream to be filled or <br />altered. <br />7. The city may limit certain development activities near a stream to specific months in order to <br />minimize impacts on water quality and wildlife habitat. <br />8. The city may apply additional conditions or restrictions, or require specific construction <br />techniques, in order to minimize impacts to stream systems and their buffers. <br />9. Stream compensatory mitigation shall not occur in areas having high-quality terrestrial <br />habitat. <br />C. Voluntary Daylighting of Streams in Pipes and Culverts. <br />1. To encourage daylighting of streams in pipes and culverts, the planning director may modify <br />development standards as set out in subsection C.2 of this section when the applicant submits a <br />plan for daylighting that meets the following criteria: <br />a. The plan is prepared by a qualified professional; <br />b. The ecological functions of the daylighted waters and adjacent area are improved so <br />the new riparian corridor is compatible with and protects the ecological functions of the
