(1) The department shall establish a program of technical and financial assistance and incentives to counties and cities to encourage and facilitate the adoption and implementation of comprehensive plans and development regulations throughout the state.

(2) The department shall develop a priority list and establish funding levels for planning and technical assistance grants both for counties and cities that plan under RCW 36.70A.040. Priority for assistance shall be based on a county's or city's population growth rates, commercial and industrial development rates, the existence and quality of a comprehensive plan and development regulations, the presence of overburdened communities, and other relevant factors. The department shall establish funding levels for grants to community-based organizations for the specific purpose of advancing participation of vulnerable populations and overburdened communities in the planning process.

(3) The department shall develop and administer a grant program to provide direct financial assistance to counties and cities for the preparation of comprehensive plans under this chapter. The department may establish provisions for county and city matching funds to conduct activities under this subsection. Grants may be expended for any purpose directly related to the preparation of a county or city comprehensive plan as the county or city and the department may agree, including, without limitation, the conducting of surveys, inventories and other data gathering and management activities, the retention of planning consultants, contracts with regional councils for planning and related services, and other related purposes.

(4) The department shall establish a program of technical assistance:

(a) Utilizing department staff, the staff of other state agencies, and the technical resources of counties and cities to help in the development of comprehensive plans required under this chapter. The technical assistance may include, but not be limited to, model land use ordinances, regional education and training programs, and information for local and regional inventories; and

(b) Adopting by rule procedural criteria to assist counties and cities in adopting comprehensive plans and development regulations that meet the goals and requirements of this chapter. These criteria shall reflect regional and local variations and the diversity that exists among different counties and cities that plan under this chapter.

(5) The department shall provide mediation services to resolve disputes between counties and cities regarding, among other things, coordination of regional issues and designation of urban growth areas.

(6) The department shall provide services to facilitate the timely resolution of disputes between a federally recognized Indian tribe and a city or county.

(a) A federally recognized Indian tribe may request the department to provide facilitation services to resolve issues of concern with a proposed comprehensive plan and its development regulations, or any amendment to the comprehensive plan and its development regulations.

(b) Upon receipt of a request from a tribe, the department shall notify the city or county of the request and offer to assist in providing facilitation services to encourage resolution before adoption of the proposed comprehensive plan. Upon receipt of the notice from the department, the city or county must delay any final action to adopt any comprehensive plan or any amendment or its development regulations for at least 60 days. The tribe and the city or county may jointly agree to extend this period by notifying the department. A county or city must not be penalized for noncompliance under this chapter due to any delays associated with this process.

(c) Upon receipt of a request, the department shall provide comments to the county or city including a summary and supporting materials regarding the tribe's concerns. The county or city may either agree to amend the comprehensive plan as requested consistent with the comments from the department, or enter into a facilitated process with the tribe, which must be arranged by the department using a suitable expert to be paid by the department. This facilitated process may also extend the 60-day delay of adoption, upon agreement of the tribe and the city or county.

(d) At the end of the 60-day period, unless by agreement there is an extension of the 60-day period, the city or county may proceed with adoption of the proposed comprehensive plan and development regulations. The facilitator shall write a report of findings describing the basis for agreements or disagreements that occurred during the process that are allowed to be disclosed by the parties and the resulting agreed-upon elements of the plan to be amended.

(7) The department shall provide planning grants to enhance citizen participation under RCW 36.70A.140.

(8) The department shall develop, in collaboration with the department of ecology, the department of fish and wildlife, the department of natural resources, the department of health, the emergency management division of the military department, as well as any federally recognized tribe who chooses to voluntarily participate, and adopt by rule guidance that creates a model climate change and resiliency element that may be used by counties, cities, and multiple-county planning regions for developing and implementing climate change and resiliency plans and policies required by RCW 36.70A.070(9), subject to the following provisions:

(a) The model element must establish minimum requirements, and may include model options or voluntary cross-jurisdictional strategies, or both, for fulfilling the requirements of RCW 36.70A.070(9);

(b) The model element should provide guidance on identifying, designing, and investing in infrastructure that supports community resilience to climate impacts, including the protection, restoration, and enhancement of natural infrastructure as well as traditional infrastructure and protecting and enhancing natural areas to foster resiliency to climate impacts, as well as areas of vital habitat for safe passage and species migration;

(c) The model element should provide guidance on identifying and addressing natural hazards created or aggravated by climate change, including sea level rise, landslides, flooding, drought, heat, smoke, wildfires, and other effects of reasonably anticipated changes to temperature and precipitation patterns; and

(d) The rule must recognize and promote as many cobenefits of climate resilience as possible such as climate change mitigation, salmon recovery, forest health, ecosystem services, and socioeconomic health and resilience.
