The purpose of this Title is to establish regulations pertaining to development which protect designated critical areas, as defined by the Washington State Growth Management Act (GMA) (RCW 36.70A). The GMA requires the use of "best available science," also as defined in that law, in developing policies and development regulations to protect the functions and values of critical areas, in addition to, giving special consideration to conservation or protection measures necessary to preserve or enhance anadromous fisheries. GMA-designated critical areas, all of which are present in Kittitas County, include: Critical aquifer recharge areas, fish and wildlife habitat conservation areas, frequently flooded areas, geologically hazardous areas, and wetlands. The regulations of this Title are intended to:
1. 
Provide for no net loss of the function and values of critical areas;
2. 
Conserve, protect, and; where feasible, restore critical areas and their functions and values;
3. 
Protect unique, fragile and/or valuable elements of the environment, including ground and surface waters, anadromous fish species, and other fish and wildlife and their habitats;
4. 
Protect the public health, safety, and general welfare from hazards associated with critical areas;
5. 
Further the goals and objectives of the Kittitas County Comprehensive Plan and all of its elements;
6. 
Implement the goals and requirements of the Washington Growth Management Act (RCW Chapter 36.70A);
7. 
Allow for reasonable use of all properties in Kittitas County.

Mitigation banking and in-lieu fee mitigation. The County may approve mitigation banking and/or in-lieu fee mitigation as a form of compensatory mitigation for wetland and fish and wildlife habitat conservation area impacts when the provisions of this Title require mitigation and when the use of a mitigation bank/in-lieu fee program will provide equivalent or greater replacement of critical area functions and values when compared to conventional permittee-responsible mitigation. Mitigation banks and in-lieu fee program shall only be used when it can be demonstrated that they provide significant ecological benefits including long-term conservation of critical areas, important species, habitats and/or habitat linkages, and when they are documented to provide a viable alternative to the piecemeal mitigation for individual project impacts to achieve ecosystem-based conservation goals. Mitigation banks and in-lieu fee programs shall not be used unless they are certified in accordance with applicable federal and state mitigation rules and expressly authorized through County legislative action.

1. 
Administrative procedures and rules. The administrative procedures followed during the critical area review process shall conform to the standards and requirements of all development and alterations. This shall include, but not be limited to, timing, appeals, and fees associated with applications covered by this Title.
2. 
General requirements.
a. 
Submittal. Prior to the County's consideration of any proposed alteration or development not found to be exempt under KCC § 17A.01.050, the applicant shall submit to the County complete information regarding the critical area on the application for the underlying development, on forms provided by the County.
b. 
As part of critical areas review, the County shall:
i. 
Verify the information submitted by the applicant;
ii. 
Evaluate the project area and vicinity for critical areas and buffers;
iii. 
Determine whether the applicant is required to seek additional critical area consultation with qualified professionals and/or agencies, which may include a joint site visit with County staff, agency staff, and/or qualified professionals; (1) This additional consultation may be required for, but is not limited to, areas which contain unmapped critical areas and/or difficult mitigation circumstances.
iv. 
Determine whether the proposed development is likely to impact the functions or values of critical areas; and
v. 
Determine if the proposed development avoids impacts or adequately addresses the impacts to the critical area and buffer associated with the alteration or development.
c. 
Make a review determination:
i. 
No critical areas present. If after a site visit the director's analysis indicates that the project area is not within or adjacent to a critical area or buffer and that the proposed alteration or development is unlikely to degrade the functions or values of a critical area, then the Director shall rule that the critical area review is complete and note on the underlying application the reasons that no further review is required. A summary of this information shall be included in any staff report or decision on the underlying permit.
ii. 
Critical areas present, but no impact - Waiver. If the Director determines there are critical areas within or adjacent to the project area, but that the best available science shows that the proposed alteration or development is unlikely to degrade the functions or values of the critical area(s) or buffer(s), the Director may waive the requirement for a critical areas report. A waiver may be granted if there is substantial evidence that all of the following requirements will be met:
(a) 
There will be no alteration of the critical area or associated riparian management zone or buffer;
(b) 
The development proposal will not negatively impact a critical area or buffer.
iii. 
Critical areas may be affected by proposal. If the Director determines that a critical area or areas or buffer(s) may be affected by the proposal, then the Director shall notify the applicant that a critical areas report must be submitted prior to further review of the project, as described in KCC § 17A.01.080. The Director may use the following indicators to assist in determining the need for a critical areas report:
(a) 
Indication of a critical area on the county critical areas maps that may be impacted by the proposed alteration or development;
(b) 
Information and scientific opinions from appropriate agencies, including, but not limited to, the Washington State Departments of Fish and Wildlife and Ecology;
(c) 
Documentation, from a scientific or other reasonable source, of the possible presence of a critical area; or
(d) 
A finding by a qualified professional, or a reasonable belief by the Director, that a critical area may exist on or adjacent to the site of the proposed alteration or development.
d. 
Effect of director's determination. A determination regarding the apparent absence of one or more critical areas by the Director is not an expert certification regarding the presence of critical areas and the determination is subject to possible reconsideration and reopening if new information is received. If the applicant wants greater assurance of the accuracy of the critical area review determination, the applicant may choose to hire a qualified professional to provide such assurances.
3. 
Request for technical assistance. The Director may engage technical consultants or agencies with expertise to provide third party review and interpret critical area data and findings submitted by or on behalf of the applicant in instances where County staff lack the resources or expertise to review these materials. An applicant may be required to pay for or reimburse the County for the review costs incurred.
4. 
Pre-qualification of consultants. The Director may prepare and maintain a list of qualified technical consultants and firms that meet the qualified professional standards detailed in KCC § 17A.01.610. Any proposed consultant whose name is not on the list may submit a statement of qualifications including information on experience in the preparation of critical area studies, years of experience, and sample work. Upon approval of the submitted qualifications, the Director shall add the name to the list of qualified consultants. The Director may reject data and findings from non-pre-qualified consultants or require a third-party review per KCC § 17A.01.610(3).

This Title shall apply as an overlay and in addition to zoning and other regulations adopted by the County.
2. 
Any individual critical area adjoined by another type of critical area shall have the buffer and meet the requirements that provide the most protection to the critical areas involved. When any existing regulations, easement, covenant, or deed restriction conflicts with this Title that which provides more protection to the critical area shall apply.
3. 
These critical areas regulations shall apply concurrently with review conducted under the State Environmental Policy Act (SEPA), as locally adopted.
4. 
Compliance with the provisions of this Title does not constitute compliance with other federal, state, and local regulations and permit requirements that may be required (for example, Hydraulic Project Approval [HPA] permits, Section 106 of the National Historic Preservation Act, U.S. Army Corps of Engineers Section 404 permits, National Pollution Discharge Elimination System permits). The applicant is responsible for complying with these requirements, apart from the process established in this Title.
