Each local planning jurisdiction in which the water utility provides service will review the relevant water system planning information and provide a signed consistency statement to the utility for submittal to the Department of Health. If the local planning agency will not respond,the highest authority within the utility(chair of governing body, executive director of private companies, etc.)must sign to verify consistency of the plan information. Water System Name: Lake Christine Community Club Water System PWS ID: 43793-3 Planning Document Title: Lake Christine Community Club WSP Plan Date: July 2010 Local Planning Jurisdiction: Mason County Page(s)in Consistency Statement Planning (Reference Municipal Water Law Section 5 and 8, Document Yes—No—Not (completed by Applicable amendment to chapter 90.03.386 and chapter 43.20 RCW) uli The retail service area,and any other areas not served by a separate public water Section 1.6 system,and land use identified in the WSP is consistent with the adopted to 1.8 comprehensive plan and adopted development regulations and policies. For WSPs only: The growth projection used to forecast water demand for the Section 2.2 retail service area is consistent with the adopted city/county's population growth projections(and commercial development projection if applicable). If a different growth projection was used,the alternative growth projection and methodology proposed is acceptable based on explanation given. For WSPs only: New potential large water users(that may have a significant none impact on the water system)that the city/county is aware of have been identified in the WSP.

Shelton WA 98584 Re: Lake Christine WSP consistency Checklist To whom it may concern; Enclosed you will find a consistency checklist for the Lake Christine Community Club Water System, WSID 43793-3. The system serves the community located at Lake Christine in rural north Mason County. The relevant sections of the Water System Plan are included for your review, if you would like to have additional portions or the entire plan sent to you,please feel free to contact me at the number above, or at jester@nwwatersystems.com. If we do not receive any response within the next 30 days we will assume there were no questions or objections to the plan. Thank you for your time and attention. Sincerely NORTHWEST WATER SYSTEMS, INC. Jester Purtteman,EIT Cc: \Projects\10031002\11082301.doc �w -y Direction below is provided as guidance for consistency verification. This • list is not comprehensive. For service area: A copy of the adopted land use/zoning map that corresponds to the service area should be included. The uses provided in the WSP should be consistent with the adopted land use/zoning map. Water systems may have policies on extensions of water service outside of their existing boundaries. These must be consistent with the local planning jurisdiction's (both city and county) adopted comprehensive plan and development regulations. Under the Growth Management Act(GMA), domestic water service is considered both an urban and rural service. Unless the comprehensive plan and development regulations specifically limit water service or have an alternative definition of rural service than what is provided in the GMA, water service is allowed anywhere within the county. For demand forecasting: 4 Water demand forecasts for the next six years and the 20-year planning horizons should be included. These forecasts should be consistent with the local population growth rate projections. If the local population growth rate projections are not used, provide a detailed explanation on why the projections chosen more accurately describe the expected growth rate. Explain how it is consistent with the adopted land use. Potential large water users may be identified by the following sources of information: • Local planning agency • Water utility • Economic Development Council I Attachment 5 2 March 2004 Revision I One lot is an island on the lake, and two lots are located across the lake from the distribution system, inaccessible without additional construction. Those lots are not presently occupied or served by the water system, but are within the boundary of the service area. Several lots have been combined into a single tax parcel and built upon, leading to some lot consolidation. There are currently 54 separate tax parcels within the accessible service area. Through multiple lot ownership, are 38 lot owning members of Lake Christine Community Club Inc. The service area has a single zoning designation by Mason County. The area is zoned as Rural 20 acre minimum lot size, although the lots were platted prior to this designation to a significantly smaller size. The largest lot in the plat was the community park, which is 1.5 acres. The majority of lot sizes range from ''A to 1 acre, with a couple of parcels nearly 1.5 acres in size through the combination of smaller lots. Currently the entire area is used as residential and recreational lots with the majority of the lots vacant. Future zoning is anticipated to remain unchanged, and the rural use is anticipated to continue for the entire 20 year planning period. The entire service area drains into Lake Christine, which is a large portion of the quarter- quarter section. 1.6 Future Service Area The existing service area will not change and consists of the entirety of SW quarter of the NW quarter of Section 20, Township 23, Range 2 West, W.M as depicted in the Service area map found on the following pages. Larger maps are available in Chapter 10. For planning purposes it is assumed that the final number of lots could be divided back to the original count of 64. 1.7 Service Area Agreements This system is not within an area governed by the Public Water System Coordination Act. In addition,there are no adjacent public water systems.

Water Wheeling will not be necessary or allowed. Annexation Annexation will not serve as a term of providing service. Direct Connection and Satellite Systems No service will be provided to Satellite Systems. All direct connection and growth will be provided by the owner of the system. Design and Performance Standards All design and construction shall be completed under the direction of the owner. A project report detailing design and construction standards shall be submitted for all significant additions and upgrades to the system. Standard details for pipe replacement and new service connection details are included in Section 7. Outside Customers and Improvement Districts The system will not serve any outside customers or districts. Urban Growth Area The system is not within urban growth area. Late-Comer Agreements Late corner agreements do not apply to the system Oversizing The existing distribution system is capable of serving the entire service area but is inadequate to provide fireflow. No future expansion in capacity or service area is anticipated. Cross-Connection Control Program The cross-connection control program has been accepted by the owner. A cross connection control specialist will be retained by the Lake Christine Community Club Inc. Additional information regarding Cross Connection is included in section 10. Extension No extensions are anticipated or proposed; however, if an extension becomes desirable, the extension of the system will be completed only under the direction of the system owner. All costs associated with an extension will be paid for by the future development. 1.9 Satellite Management Currently the system is managed by Ken Loomis, WDS. LCCCWS does not have a satellite management agency. Northwest Water Systems,Inc. - 7 - Lake Christine Community Club Planning-Management-Engineering Water System Plan 1 2.0 BASIC PLANNING DATA 2.1 Current Population and Water Use The current population of the LCCC Water System is based upon an informal survey of the system by the board. From this survey it was determined that of the 17 system connections, 13 of them were full time residences. 4 connections are used for part time cabins. Full time residences are assumed to be used 365 days a year, while recreational sites are used only during vacation peaks, averaging about 25 days of use per connection per year. For the purpose of determining ADD per ERU, vacation usage is neglected. The entire system usage is then assumed to be from 13 full time residences. The system is then evaluated based on 1 ERU per full time household. This has the effect of slightly over- estimating the actual average consumption, but given the current high ratio of full time to part time water use,this assumption will not cause significant error in the analysis. 2.2 Projected Population and Water Use Water use is entirely residential and recreational (vacation home) in nature, with the exception of uses associated with operation of the system, such as flushing. Analysis of the water quality data indicates that minimal flushing is necessary. Four dead end mains exist, two of which are located at the north and south east ends of the distribution system, and two at the ends of short cul-de-sacs. The system was required to go through the existing system approval process in the 1997, which was completed in 1998. At that time the system was approved for the 15 ERU's that were then present. Since that time 3 additional connections have been desired, but not allowed due to the limited approved services. The 3 desired connections over the past 12 years are taken to represent a "typical" growth rate for the system. Therefore, since approval in 1998 there have then been 3 requests to join the system, for a growth rate of one additional connection every 4 years. This corresponds to a growth rate of approximately 1.5%, in line with county and state growth projections. For projected population growth trends, it is assumed that the 3 lots that desire water service are immediately served, and that from that time the system continues to grow at a rate of one additional service every 4 years. It is assumed that the population per ERU remains constant going forward. Table 1: Projected Population ERUs Population Current 13 37 6-year 17 48 20-year 21 60 Build-out 57 162 Water Demand Forecasting Northwest Water Systems,Inc. - 10 - Lake Christine Community Club Planning-Management-Engineering Water System Plan The previous year of source meter data was analyzed to develop the system usage model. The data was analyzed by assuming that all usage was due to the full time residential usage. While this slightly exaggerates the usage by including recreational use in the average, it provides a more conservative estimate of usage. This analysis indicates that the system has an Average Daily Demand (ADD) of 290 gpd. This is consistent with the demographics of the system, which has small wooded lots with minimal out-door watering. The maximum month's average demand (MMAD) was determined to be 452 gpd from the source meter records. Using the standard 1.7 multiplier for systems in western Washington, the calculated maximum daily demand is therefore 769 gpd. The ratio of ADD to MDD is 2.67, which is slightly higher than typical, likely because of the recreational lots seasonal use. In summary the usage characteristics used in the analysis of the system are: ADD: 299 gpd MMAD: 452 gpd MDD: 769 gpd Anticipated Growth: The system has not been allowed to grow since 1998 because of the capacity of its single booster pump. The community has three outstanding requests for water service which it cannot provide due to its lack of capacity. It is anticipated that upon approval the system will soon have three additional connections. It is assumed that all new connections will be full time residences. Table two shows the projected growth in services, flow requirements, and annual use for the community over the next 20 years. The growth rate is based on historical growth trends in the area, and is in-line with the Mason County Comprehensive Plan growth projections. Water use projections are made for no savings, and 10%reduction in use with the planned WUE measure.
