The inunda tion <br />could introduce foreign elements into local waterways, resulting in destruction of downstream habitat and <br />detrimental effects on many species of animals, especially endangered species such as coho salmon. The <br />extent of the vulnerability of the environment is the same as the exposure of the environment. <br />8.7. FUTURE TRENDS IN DEVELOPMENT <br />Land use in the planning area will be directed by comprehensive plans adopted under Washington’s GMA. <br />These comprehensive plans, in conjunction with “critical areas” regulations adopted by municipal planning <br />partners, provide the regulatory and planning capability to address the risks associated with dam failures. <br />Dam failure is currently not addressed as a standalone hazard under these programs, but flooding is. <br />Municipal planning partners have established comprehensive policies regarding sound land use in identified <br />flood hazard areas. Most of the areas vulnerable to severe impacts from dam failure intersect the mapped
