A.
It is the policy of the city to require site planning to avoid or minimize damage to wetlands wherever possible; to require that activities not dependent upon a wetland location be located at upland sites; to achieve no net loss of wetlands by requiring restoration or enhancement of degraded wetlands or creation of new wetlands to offset losses that are unavoidable.
B.
The purposes of this chapter are to protect the public health, safety, and welfare by:
1.
Preventing the adverse impacts of development within and adjacent to wetlands;
3.
Alerting appraisers, assessors, owners, and potential buyers or lessees to the development limitations of wetlands;
4.
Providing city officials with information to evaluate, approve, condition, or deny public or private development proposals;
5.
Implementing the policies of the Growth Management Act, the State Environmental Policy Act, Chapter 43.21C RCW, city comprehensive plan, as updated, and all other present and future city environmental and community plans and programs; and
6.
Preventing the net loss of wetland functions and values.
C.
It is the intent of the city that activities in or affecting wetlands not threaten public safety, cause nuisances, or destroy or degrade natural wetland functions and values by:
1.
Impeding flood flows, reducing flood storage capacity, or impairing natural flood control functions, thereby resulting in increased flood heights, frequencies, or velocities on other lands;
2.
Increasing water pollution through location of domestic waste disposal systems in wetlands; unauthorized application of pesticides and herbicides; disposal of solid waste at inappropriate sites; creation of unstable fills; or the destruction of wetland soils and vegetation;
3.
Increasing erosion;
4.
Decreasing breeding, nesting, and feeding areas for many species of waterfowl and shorebirds, including those that are rare, endangered, threatened, or of local significance;
5.
Interfering with the exchange of nutrients needed by fish and other forms of wildlife;
6.
Decreasing habitat for fish and other forms of wildlife;
7.
Adversely altering the recharge or discharge functions of wetlands, thereby impacting groundwater or surface water supplies;
8.
Significantly altering wetland hydrology and thereby causing either short or long term changes in vegetational composition, soils characteristics, nutrient cycling, or water chemistry;
9.
Destroying sites needed for education and scientific research, such as outdoor biophysical laboratories, living classrooms, and training areas; or
10.
Destroying or damaging aesthetic and property values, including significant public view sheds.
D.
Best available science shall be applied to all wetlands ratings, delineation, and mitigation measures as set forth in this chapter. Sources for this science shall include the latest edition of the State Department of Ecology's Washington State Wetland Rating System for Western Washington and the latest edition of the Department's Guidance on Wetland Mitigation in Washington State: Parts 1 and 2.
