Public works will reserve additional engineering comments for the Civil Public Review process. No additional survey requirements as part of the preliminary long plat.

Washington State Department of Health – Office of Drinking Water WSDOH (Office of Drinking Water) submitted the following comments: How does this application differ from a previous application entitled “Ph 2 Div 7” that identified 148 homes? Staff Response: Applicant provided a response to Washington State Department of Health (Office of Drinking Water). The applicant stated that “Suncadia’s Phase 2 Division 7 final plat was approved a couple of years ago. This plat is taking 14 platted lots in “Ph 2 Div 7” and sub-dividing into 24 total platted lots (+10). Suncadia acknowledges that the current DOH approved water connection count would be exceeded if all preliminary platted developments under review by the County received final plat. Suncadia Resort is actively engaged with Suncadia Water Company’s update of the resort water facilities capacity analysis model to allow for additional connections. As the utility service provider, Suncadia Water Company is the lead in working with a water modeling consultant and the DOH. The accounting method used for allowed connections is an antiquated method based on 20-year-old assumptions, not actual water usage data. Suncadia Water Company has updated their water facilities capacity analysis with actual usage data and has submitted that to DOH for review. This updated model is to facilitate approval of updated and more accurate connection counts. Because the discussion on the update of the water connection model between Suncadia Water Company and the DOH has not been concluded, Suncadia proposes an alternative approach in keeping under the allowed 1,501 connections. Suncadia’s Phase 1 Division 14 development received preliminary plat, but Suncadia will not be working toward final plat for this development in 2024. If the number of water connections anticipated for the Phase 1 Division 14 development were excluded from the total connection table, there are enough water connections allowed for the final plat of Nelson Stream (10 additional units). Removing the 39 connections earmarked or Phase 1 Division 14 from the capacity analysis and adding in the units for the Suncadia Social plat (previously approved 42 units) and Nelson Stream Plat (10), calculates 16 allowed connections remaining. In summary, if the Nelson Stream plat were approved before the Phase 1 Division 14 plat, there are enough water connections available for plat LP-24-00003. Suncadia will continue coordination with Suncadia Water Company and the Department of Health on the updated capacity analysis model. Suncadia appreciates DOH’s swift and thorough coordination, review, and approval of the utility company’s applications for updated approved connections.” Staff therefore states that Suncadia has adequately addressed the comments submitted by WSDOH – Office of Drinking Water.
