[ 2010 c 46 § 1; 1921 c 185 § 1; RRS § 9663; ]
The county legislative authority of any county may adopt a comprehensive flood control management plan for any drainage basin that is located wholly or partially within the county.
A comprehensive flood control management plan shall include the following elements:
Designation of areas that are susceptible to periodic flooding, from inundation by bodies of water or surface water runoff, or both, including the river's meander belt or floodway;
Establishment of a comprehensive scheme of flood control protection and improvements for the areas that are subject to such periodic flooding, that includes: (a) Determining the need for, and desirable location of, flood control improvements to protect or preclude flood damage to structures, works, and improvements, based upon a cost/benefit ratio between the expense of providing and maintaining these improvements and the benefits arising from these improvements; (b) establishing the level of flood protection that each portion of the system of flood control improvements will be permitted; (c) identifying alternatives to in-stream flood control work; (d) identifying areas where flood waters could be directed during a flood to avoid damage to buildings and other structures; and (e) identifying sources of revenue that will be sufficient to finance the comprehensive scheme of flood control protection and improvements;
Establishing land use regulations that preclude the location of structures, works, or improvements in critical portions of such areas subject to periodic flooding, including a river's meander belt or floodway, and permitting only flood-compatible land uses in such areas;
Establishing restrictions on construction activities in areas subject to periodic floods that require the flood proofing of those structures that are permitted to be constructed or remodeled; and
Establishing restrictions on land clearing activities and development practices that exacerbate flood problems by increasing the flow or accumulation of flood waters, or the intensity of drainage, on low-lying areas. Land clearing activities do not include forest practices as defined in chapter 76.09 RCW.
A comprehensive flood control management plan shall be subject to the minimum requirements for participation in the national flood insurance program, requirements exceeding the minimum national flood insurance program that have been adopted by the department of ecology for a specific floodplain pursuant to RCW 86.16.031, and rules adopted by the department of ecology pursuant to RCW 86.26.050 relating to floodplain management activities. When a county plans under chapter 36.70A RCW, it may incorporate the portion of its comprehensive flood control management plan relating to land use restrictions in its comprehensive plan and development regulations adopted pursuant to chapter 36.70A RCW.
[ 1991 c 322 § 3; ]
A comprehensive flood control management plan that includes an area within which a city or town, or a special district subject to chapter 85.38 RCW, is located shall be developed by the county with the full participation of officials from the city, town, or special district, including conservation districts, and appropriate state and federal agencies. Where a comprehensive flood control management plan is being prepared for a river basin that is part of the common boundary between two counties, the county legislative authority of the county preparing the plan may allow participation by officials of the adjacently located county.
Following adoption by the county, city, or town, a comprehensive flood control management plan shall be binding on each jurisdiction and special district that is located within an area included in the plan. If within one hundred twenty days of the county's adoption, a city or town does not adopt the comprehensive flood control management plan, the city or county shall request arbitration on the issue or issues in dispute. If parties cannot agree to the selection of an arbitrator, the arbitrator shall be selected according to the process described in *RCW 7.04.050. The cost of the arbitrator shall be shared equally by the participating parties and the arbitrator's decision shall be binding. Any land use regulations and restrictions on construction activities contained in a comprehensive flood control management plan applicable to a city or town shall be minimum standards that the city or town may exceed. A city or town undertaking flood or stormwater control activities consistent with the comprehensive flood control management plan shall retain authority over such activities.
[ 1991 c 322 § 4; ]
A county may create one or more advisory committees to assist in the development of proposed comprehensive flood control management plans and to provide general advice on flood problems. The advisory committees may include city and town officials, officials of special districts subject to chapter 85.38 RCW, conservation districts, appropriate state and federal officials, and officials of other counties and other interested persons.
