irrigates their properties which brings the water table up and could contaminate the aquifer and negatively affect the surface water and drainage patterns. They also commented that the lots are in the floodplain. 13.2.1 Applicant Response: This proposed ten lot plat is not completely within the floodplain. Only a small portion of the plat is in the 100 year and 500-year floodplain and is in the back portion of the lots. Kittitas County does allow people to build within the 100-year floodplain as long as flood development requirements are met. The plat proposes a Group B water system that will be approved by Kittitas County Public Health. Per the Kittitas County Health Department's comment letter and county code, the proposed plat is allowed to apply for individual septic systems. 13.2.2 Hearing Examiner Finding: There is sufficient space outside of the 100-year floodplain to build on all of the proposed lots. Kittitas County Public Health will have to approve all septic systems including soil logs prior to final plat approval that looks at things like groundwater. The Hearing Examiner sets as a condition of approval that the lots not be flood irrigated. 13.3 Paula Thompson: Paula Thompson commented on the 2022 comprehensive plan and rezone update saying it was inadequate and that the current SEPA checklist does not identify wetlands and perennial springs. She also commented on irrigation rights and delivery systems as well as drainage patterns. She had concerns about lots without fire hydrants and that a turn lane should be required on Thorp Hwy to turn onto Thorp Landing Lane. 13.3.1 Applicant Response: Ms. Thompson did not file an appeal to the SEPA as part of the 2022 comprehensive plan and zoning change. She has now filed a petition to the Eastern Washington Growth Management Hearings Board but that petition does not matter as this application was vested prior to the petition as the county deemed it complete prior to that petition. 13.3.2 Hearing Examiner Finding: The applicant provided a critical areas report done by a qualified professional that states there are no jurisdictional wetlands on the property and one Type F stream on the north side of the property. An irrigation system approved by Westside Irrigating Company will be required prior to final plat approval. Kittitas County received a transportation concurrency application from the applicant and found that no mitigation measures are required for the creation of 10 lots in this plat. 14. The Hearing Examiner has reviewed all the comments submitted and has conditioned this decision to address the concerns noted. 15. In review of this proposal, it is important to consider the goals and policies of the comprehensive plan, applicable county code, public and agency comments, any identified environmental concerns and state and federal requirements. Identified below is the Hearing Examiner's analysis and consistency review for the subject application. LP-23-00001 Thorp Landing Long Plat Page 8 of 17
