B. Use of Exemptions.
1. Each department within the county that receives an application for a license or, in the case of governmental proposals, the department initiating the proposal, shall determine whether the license and/or the proposal is exempt. The department’s determination that a proposal is exempt shall be final and not subject to administrative review. If a proposal is exempt, none of the procedural requirements of this chapter apply to the proposal. The county shall not require completion of an environmental checklist for an exempt proposal.
2. In determining whether or not a proposal is exempt, the department shall make certain the proposal is properly defined and shall identify the governmental licenses required (WAC 197-11-060). If a proposal includes exempt and nonexempt actions, the department shall determine the lead agency, even if the license application that triggers the department’s consideration is exempt.
3. If a proposal includes both exempt and nonexempt actions, the county may authorize exempt actions prior to compliance with the procedural requirements of this chapter, except that:
a. The county shall not give authorization for:
(1) Any nonexempt action;
(2) Any action what would have an adverse environmental impact; or
(3) Any action that would limit the choice of alternatives;
b. A department may withhold approval of an exempt action that would lead to modification of the physical environment, when such modification would serve no purpose if nonexempt action(s) were not approved; and
c. A department may withhold approval of exempt actions that would lead to substantial financial expenditures by a private applicant when the expenditures would serve no purpose if nonexempt action(s) were not approved.
(Amended: Ord. 2018-01-09)

D. Critical Areas.
1. Clark County designates the following as critical areas, in which the exemptions as specified in subsection (E) of this section do not apply:
a. Shoreline Management Areas. Land and water areas under jurisdiction of the Shoreline Management Act are critical areas. These shorelines of the county are mapped in the Clark County shoreline master program, which maps are incorporated in this chapter by reference. All development subject to shorelines substantial development permits, shorelines conditional use permits, and shorelines variance permits are subject to SEPA, except that SEPA review shall not be required for the exempt shoreline developments listed in Section 40.460.230(B); provided, that no part of the exempt shoreline development is undertaken on lands covered by water as defined in WAC 197-11-756. In addition, the minor repair or replacement of structures such as pilings, ramps, floats, or mooring buoys, or minor repair, alteration, or maintenance of docks that are specifically exempted within WAC 197-11-800(3) shall also be exempt from SEPA review.
b. Floodplains. Except for exempt shoreline developments listed in Section 40.570.090(D)(1)(a) that are above the ordinary high water mark, or other development outside of shorelines areas that do not require a flood hazard permit under Chapter 40.420, all areas within special flood hazard areas delineated by the Federal Emergency Management Agency (FEMA) under the Flood Insurance Study for Clark County are critical areas. These special flood hazard areas are designated on FEMA’s Flood Insurance Rate Maps (FIRM), which are incorporated in this chapter by reference.
c. Wetlands subject to the provisions of Chapter 40.450 are critical areas.
(1) Exemptions listed in Section 40.450.010(C) shall be exempt from SEPA.
(2) Other exemptions as specified in Section 40.570.090(E) do not apply unless authorized by a Type I wetland permit under Section 40.450.040(G)(1)(a).
d. The following critical areas regulation ordinances but only for personal wireless service facilities:
(1) Chapter 40.440, Habitat Conservation;
(2) Chapter 40.430, Geologic Hazard Areas;
(3) Chapter 40.410, Critical Aquifer Recharge Areas (CARAs).
2. The scope of environmental review of actions within these areas shall be limited to:
a. Documenting whether the proposal is consistent with the requirements of the applicable critical areas ordinance; and
b. Evaluating potentially significant impacts on the critical area resources not adequately addressed by the comprehensive plan and implementing ordinances, including any additional mitigation measures needed to protect the critical areas in order to achieve consistency with SEPA and other applicable environmental review laws.
3. The county shall treat proposals located wholly or partially within a critical area no differently than other proposals under this chapter, making a threshold determination for all such proposals. The county shall not automatically require an EIS for a proposal merely because it is proposed for location in a critical area.
