Exhibit B <br />ORDINANCE Exhibit A - Page 33 of 55 <br />6. When the city finds, based upon a site-specific wetland analysis, that impacts on the wetland from a <br />proposed development can only be mitigated by a greater buffer width. <br />C. General Mitigation Measures. Implementation of all of the following general mitigation measures <br />allows use of the reduced wetland buffers listed in Table 37.3: <br />1. Direct lights away from the wetland. <br />2. Locate activity that generates noise away from the wetland. <br />3. Route all new, untreated runoff away from the wetland while ensuring wetland is not <br />dewatered. <br />4. Establish covenants limiting use of pesticides within one hundred fifty feet of the wetland. <br />5. Apply integrated pest management. <br />6. Retrofit stormwater detention and treatment for roads and existing adjacent development. <br />7. Prevent channelized flow from lawns that directly enters the buffer. <br />8. Infiltrate or treat, detain, and disperse into buffer new runoff from impervious surfaces and <br />new lawns. <br />9. Use privacy fencing; plant dense vegetation to delineated buffer edge and discourage <br />disturbance using vegetation appropriate for the ecoregion; place the wetland and its buffer in a <br />separate tract. <br />10. Use best management practices to control dust. <br />D. Where wetland functions have been improved due to voluntary implementation of an approved <br />stewardship, restoration and/or enhancement plan that is not associated with required mitigation or <br />enforcement, the standard wetland buffer width shall be determined based on the previously <br />established wetland category and habitat score as documented in the approved stewardship and <br />enhancement plan. <br />19.37.120 WETLAND ALTERATION THRESHOLDS AND COMPENSATION. <br />A. Wetland Preservation/Alteration Thresholds. <br />1. Category I Wetlands. All category I wetlands shall be preserved except as provided in this <br />chapter. The planning director, using the review process as described in EMC Title 15, Local <br />Project Review Procedures, may allow alteration of category I wetlands: <br />a. Where alteration is allowed pursuant to EMC 19.37.050; or <br />b. The alteration is to allow a public park or public recreational use; provided, that <br />there is no feasible and reasonable alternative to making the alteration and the <br />alteration does not act to degrade the functions of the wetland, or the alteration <br />proposed has a reasonable likelihood of being fully mitigated;
