Program Consistency Statement Checklist
This checklist is intended to ensure consistency of water system planning documents with
adopted local comprehensive plans and development regulations. 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.

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

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.

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.

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.
