Secondary Water Impact Fee Facilities Plan I – Executive Summary
Wolf Creek Water and Sewer Existing LOS Date: November 1, 2021
Improvement District PAGE 1 Last Saved: March 25, 2022
I. Executive Summary
This Impact Fee Facilities Plan (IFFP) is a document that considers the secondary water needs of the
Wolf Creek Water and Sewer Improvement District (District, WCWSID) through buildout1. It
identifies projects and facilities that are growth-related. Costs incurred by the WCWSID for the sole
purpose of accommodating growth may be covered, or recouped, depending on the timing of
expenditures, through the collection of impact fees2. Creation of an IFFP is prerequisite to
establishment and collection of an impact fee.
The ability of the District to serve its customers was reviewed in the categories of water rights
Annual Delivery and distribution capacity (pipe network).
The District has adequate capacity in each of these categories to serve its currently active
customers3 and does not have the capacity to serve additional customers without implementing
methods for increasing its capacities.
The District currently provides 0.36 acre-feet per year (AF/YR) of irrigation water to each Equivalent
Residential Unit (ERU) served by its secondary water system on an annual basis, which is provided by
some combination of Source Capacity and Storage Capacity. It is critical to note that an ERU in each
of the District’s three IFFPs (Culinary, Secondary, Sanitary Sewer) have different definitions. The
needs identified in each IFFP must be met independently.
To provide the existing Level of Service (LOS) to new development, the District must immediately
pursue projects to increase its Annual Delivery capacity by simultaneously increasing its water right
and storage capacities. The secondary system is currently at capacity. No growth is possible
without implementation of improvement projects as summarized in the following table. The
Recommended4 priority of implementation is:
1 Method 1.c, Increase Reuse and Construct 90-AF Bridges Pond.
2 Method 1.d, Add Wolf Creek Channel as POD, Re-line Highlands Pond and Construct 52-
AF Retreat Pond
3 Method 1.e, Construct Wells, add PODs to water rights
4 Method 1.b, Acquire additional Wolf Creek Irrigation Company (WCIC) shares
5 Method 1.f, Acquire shares of other Canal Companies and construct improvements to
utilize the water purchased

1 Buildout is the point at which no additional growth is theoretically possible, given zoning restraints.
2 The establishment and collection of impact fees is codified in the Utah Code, Title 11, Chapter 36a.
3 Standby users and currently unplatted/future users are all considered new development in this IFFP. It is recognized that standby users may
have paid some portion of the costs for facilities needed to serve them at the proposed LOS. However, since the system is at capacity at
present, all newly active users (hereafter referred to as “new”, “future” or “additional” with no differentiation between standby and entirely
new users) will necessitate the acquisition of additional facilities.
4 It is recognized that some methods may be available for beneficial implementation sooner than others and multiple methods may be pursued
simultaneously or in a different order, as determined by the District.

The cost of new facilities required to meet the demand of new customers is paid by the new
customers through an impact fee collected to pay for the impact of new customers on the existing
system. The growth-related projects identified above, or other projects mentioned in this
document, as the option for their implementation may arise, will be used as the basis for the
establishment and assessment of development impact fees, which fees are developed in a separate
document, prepared by Lewis, Young, Robertson, and Burningham.
A. CERTIFICATION of Compliance with Utah State Code (11-36a-306(1)):
To the extent the following items are addressed in the IFFP dated March 25, 2022, Gardner
Engineering certifies that the following impact fee facilities plan:
1. Includes only the costs of public facilities that are:
a) allowed under the Impact Fees Act; and
b) actually incurred; or
c) projected to be incurred or encumbered within six years after the day on which each
impact fee is paid;
2. Does not include:
a) costs of operation and maintenance of public facilities;
b) costs for qualifying public facilities that will raise the level of service for the facilities,
through impact fees, above the level of service that is supported by existing residents;
c) an expense for overhead, unless the expense is calculated pursuant to a methodology
that is consistent with generally accepted cost accounting practices and the
methodological standards set forth by the federal Office of Management and Budget for
federal grant reimbursement; and
3. Complies in each and every relevant respect with the Impact Fees Act.

II. Introduction
The facilities of WCWSID are addressed in the areas of Water Rights and Annual Delivery. This
document has been prepared based on data current as of November 1, 2021.
The Impact Fee Act requires that an impact fee only be imposed when based on an Impact Fee
Facilities Plan (IFFP, Plan). An IFFP must include the following5:
A. Identify the existing level of service (LOS) for each public facility.
B. Establish a proposed level of service (LOS) for each public facility.
C. Identify any excess capacity to accommodate future growth at the proposed level of service
D. Identify demands placed upon existing public facilities by new development activity at the
proposed level of service.
E. Identify the means by which the political subdivision or private entity will meet those growth
demands identified in D, above, through
a. “Selling” the excess capacity in C, or
b. The acquisition of new capacity, which acquisition would be financed through grants, bonds,
interfund loans, impact fees and anticipated or accepted dedication of system
improvements.
WCWSID has retained Gardner Engineering to develop an IFFP to help plan for the future needs of
the secondary water system. The District has retained a separate consultant to review and establish
the District’s impact fee based on this Plan.

# Single Family Residential User Type includes all individual homes, and single-family homes in
Planned Residential Unit Developments (PRUDs). The PRUDs are The Villages, Fairway Oaks,
The Fairways, Trapper's Ridge.

B. Secondary Water Use
Secondary water use data from the 2014-2020 water years have been collated and analyzed7.
The District operates a metered secondary system to nearly all users. The golf course is partially
metered. The District considered Use data for the year 2021 as an outlier due to remarkable
conservation as a response to the current drought conditions. WCWSID has opted to plan based
on 2020 data as representative of secondary water use in the District8.

6 Data for the column Digitized Irrigated, AC is a summary of sampled lots from each user type. Aerial photography was digitized to estimate the
average irrigated acreage for each unit in the User Type.
7 Refer to the more detailed TABLE B1 in Appendix B.
8 Planning based on 2020 data will result in a plan based on a slightly-greater-than-average demand, which the District anticipates will result in
a more robust plan.

C. Secondary Water Supply
Secondary water supply from the District’s sources during the 2015-2021 water years have been
collated and analyzed. The District has opted to plan based on average supply over the years
analyzed.
Table 3 – Average Secondary Water Supply (AF), 2015-202110

TOTAL In-flow 519.1

Of significance for later use in this IFFP is the total supply from the Wolf Creek channel. This
total flow factors into calculating the average value, in AF, of a share of the WCIC. There are 791
shares of WCIC. Thus, each share of WCIC represents an average of (1,728 AF from Wolf Creek
divided by 791 shares =) 2.18 AF per year.

9 Annual usage for each user Type was provided by WCWSID.
10 The first row of this table is shown as backup for the WCWSID’s share of WCIC and is thus grayed out because the data on this line are not
summed into the calculation of WCWSID’s in-flow.

To simplify calculations throughout this document, the Average AF/unit shown in TABLE 2 on
Page 6 is used to relate each type of user to each other through means of defining an Equivalent
Residential Unit (ERU). An ERU will be defined as one dwelling in a Single-Family Residential
development with an annual use of 0.36 AF. Each other type of user will be defined as some
multiple of an ERU, based on historic usage as shown below.

Golf Course AC 1.98 5.50 87.20 480
TOTAL 1,166

WCWSID provides the following levels of service to its active users:
1. Water Rights
As of November 1, 2021, WCWSID owns 207.66 shares of the 791 total shares12 of WCIC.
The WCIC water right is written for beneficial use on 741.85 AC. Thus, the District’s owned
and leased shares are for beneficial use on (741.85 AC * 207.66 shares / 791 shares) 194.76
AC. During 2020, which is used as the base year on which to estimate demand and supply,
an average of 2.00 AF was applied to each irrigated acre in the District13. Without implying a
legal limit on the WCIC water right because this document does not presume to be a legal
opinion of water rights quantification, a value of 2.00 AF/AC is used in this document to “put
a placeholder value” on the District’s water rights. Following this “placeholder value”
methodology, WCWSID has right to apply (2.00 AF/AC * 194.76 AC) 389.52 AF of secondary
water via its shares of WCIC. The District also has right to reuse treated effluent from its
wastewater treatment plant14, which in the recent past has been an average of 35.4 AF.
The District owns contracts for 303 AF of water with the Weber Basin Water Conservancy
District under water right 35-13987 (E6249)15.

11 Reference: Utah State Code11-36a-302(1)(a)(i)
12 Approximately 50 additional shares of WCIC have been leased in each of the past several years to increase the District’s ability to provide
water in the District. The District anticipates that 42 of those shares will be available for lease until they get deeded to the District by the share
owner when land is developed. None of the leased shares will be considered, however, when determining the Existing LOS because owned
shares are an impact fee facility, but leased shares are not.
13 Refer to Table 2 – Secondary Water Use by User Type, 2020 on Page 6.
14 As long as the water under the District’s Municipal water right does not leave the District’s control (which wastewater does not since it is
collected and treated within the District boundaries), WCWSID has the right to reuse the treated effluent.
15 This right is still an unapproved application. The protest period has ended and all indications are that the application will be approved
unconditionally. This IFFP considers the application approved. The application proposes to combine several WBWCD contracts into a single
Exchange: 300 AF contract + 1 AF contract + 2 AF contract.

Wolf Creek Water and Sewer Existing LOS Date: November 1, 2021
Improvement District PAGE 8 Last Saved: March 25, 2022
The contracted amount of 303 AF is for Municipal use, meaning that the water right can be
used in either the culinary or secondary systems, as may be required in each system. The
District anticipates that approximately ½ of the total amount will be used in the secondary
system, as shown in the table below. Such statement in no way limits the District’s use of
the mentioned pending water right.

2. Annual Delivery
Annual Delivery capacity is defined as the amount of water delivered to each user on an
annual basis. Losses due to seepage, evaporation and leaks are not accounted for in this
number.
Note that if water comes into the District through the splitter from the Wolf Creek diversion,
but there is no irrigation demand to use that water, and no storage to capture that water for
later use, it will overflow back to the Wolf Creek channel. The water that overflows is not
considered part of the Annual Delivery capacity since it is not available for use when
needed.
The amount of water used in 2020 is considered adequate and is set as the District’s Annual
Delivery LOS17.
Table 6 – Annual Delivery Level of Service
ERUs Served Total delivery (AF/YR) Annual Delivery LOS
(AF/ERU/YR)
1,166 420.31 0.36

The Annual Delivery LOS is provided through a combination of two resources: source
capacity and storage capacity. The full benefits of these two resources are not realized
without each other18. The benefits of the resources are considered in tandem as a single
Annual Delivery capacity, like a mathematical equation:

16 The data in this table is best read in a progression from left to right.
It can be seen in the column “Total WR assets (AF)” that the sum of water rights (“Equivalent water rights via WCIC shares (AF)” + “35-13987
(E6249)”) was more than sufficient in 2020 to irrigate all ERUs in the District (0.46 AF/ERU of water right available compared to a wet water use
of 0.36 AF/ERU). Regarding the WCIC water right, it is simpler to track the number of AF delivered than to track the number of acres irrigated.
This table makes the jump from a water right written in terms of AC irrigated to AF delivered. Note that this IFFP anticipates that a change
application will be filed and approved to change the Type of use for the WCWSID shares to Municipal, which will put the water right in terms of
AF. This table does informally what must be done formally with the WCIC and Division of Water Rights.
17 Please refer to Table 4 – Equivalent Residential Unit Definition and User Type Comparison on page 6.
18 Source capacity is the flow of water into WCWSID. Sources currently include water from the Wolf Creek channel (based on shares of WCIC)
and pumped reuse of treated wastewater.

Wolf Creek Water and Sewer Existing LOS Date: November 1, 2021

Source Capacity + Storage Capacity = Annual Delivery LOS
The preceding equation is very simplified and does not include all the variables that effect
the LOS. The equation is given to illustrate that the District’s target LOS, Annual Delivery, is
a result of both the source and storage capacities.
For reference, WCWSID has the following source capacity, which can be delivered fully only
with the addition of storage. Additional storage would help make up the time-difference
between when the source water is available and when the water is demanded for irrigation.
TABLE 7 is included to illustrate that WCWSID has the source capacity needed to deliver
additional water with the future addition of storage capacity.
Table 7 – Source Capacity
ERUs Served Annual Supply (AF/YR) Source Capacity
(AF/ERU/YR)
1,166 519.10 0.45
The 519 AF of source water shown in TABLE 7 above exceeds the 420 AF of use shown in
TABLE 6. This indicates that 99 AF of water was measured flowing into the system but was
not used by WCWSID customers. This difference between inflow and use highlights the
relationship of Source Capacity and Storage Capacity in providing the Annual Delivery LOS.
For reference, the District’s current storage capacity is summarized in the following table.
Table 8 – Storage Capacity

Storage Capacity

Highlands Pond* 10

(approx. 28% of 120 AF nominal capacity) 34
TOTAL 75 1,166 0.06
*The Highlands Pond has a geometric capacity of 19.9 AF. Realized capacity is approximately 10 AF due to the lack of an
impermeable liner.

Without storage, the delivery of water is limited to what can be supplied on an instantaneous basis.
With storage, which acts like a battery, source water is captured when it is available and demands are low, then the stored water is distributed
out when it is demanded, even though source water into the system may be low.
Storage is of no use without water to fill it. Thus, the two capacities rely on each other to maximize the availability of Annual Supply.

2. Annual Delivery:
There is no excess capacity in the Annual Delivery LOS.
3. Distribution:
The only quantifiable excess capacity in the District’s secondary water system distribution
system is in the 12” pipeline shown on the “Existing” map in Appendix A, that extends north
and west from the primary pond through the Fairways at Wolf Creek Subdivision and to
Fairway Oaks Subdivision.
The 4,900-foot long 12” diameter line is estimated to be at approximately 50-percent
capacity.21 That pipeline was constructed in 2003. No cost information is known to exist
relating to the cost of said pipeline, so a best approximation has been developed.
A 10” culinary waterline was installed during the summer of 2017 along a portion of the
alignment of the irrigation line at a cost of $110/L.F.22 Using the Engineering News Record’s
historical Construction Cost Index23, it is estimated that the 12” pipeline was installed for
$69/L.F. in 200324, for a total pipeline cost of $338,100. All other pipelines are considered at
capacity.

20 Reference: Utah State Code11-36a-302(1)(a)(iii)
21 An 8” pipeline would suffice in this location at present, which is roughly 50% of the capacity of a 12” pipeline that would be needed at
buildout.
22 See bid tabulation in Appendix A for a 10” pipeline, 3,110 linear feet (L.F.).
23 ENR CCI, as cited by NRCS at https://www.nrcs.usda.gov/wps/portal/nrcs/main/national/technical/econ/prices/; Excel file retrieved
10/24/2017. Jan 2017 index value / Jan 2003 index value = 1.60. Thus, Jan 2017 bid price of $110/L.F. / 1.6 = estimated Jan 2003 construction
price.
24 It is estimated, based on the CCI index values that the cost to install a 10” waterline in 2003 was approximately $69/L.F. It is further estimated
that the cost difference between 3,110 L.F. of 10” pipeline in 2003 and the economies of scale that would have been realized with 4,900 L.F. of
12” pipeline in 2003 would have made the 12” unit cost roughly equal to the 10” unit cost.

proposed level of service25
WCWSID serves the Wolf Creek Resort, as well as some additional developments not in the
Resort. The Wolf Creek Resort Master Land Use Plan reproduced in Appendix A has been
reviewed and approved by the Weber County Ogden Valley Planning Commission and Weber
County Commissioners for implementation, most recently confirmed in 2014. Those parcels
that are not part of the Resort but are within the WCWSID have also been shown on the Master
Land Use Plan. The combined map is presented as a master plan map for development within
WCWSID.
Standby users and currently unplatted/future users are all considered new development in this
IFFP. It is recognized that standby users may have paid some portion of the costs for facilities
needed to serve them at the proposed LOS. However, since the system is at capacity at present,
all newly-active users (hereafter referred to as “new”, “future” or “additional” with no
differentiation between standby and entirely new users) will necessitate the acquisition of
additional facilities.
Based on data provided by WCWSID, the following growth is anticipated:

(i.e., the master land use plan identifies 1,522 Single-Family ERUs at Buildout, and 20 ERUs have been added to that value to account for
pending commercial users that would not otherwise be included in this table).

If acreage or usage by any User Type changes substantially, the next IFFP will address such
changes and may redefine an ERU. Note that an ERU in each of the District’s IFFPs27 is unique to
the utility for which the Plan is created and the associated impact fee for each utility must be
satisfied independently.

3. Distribution:
The Proposed LOS in the distribution system is to maintain a minimum pressure of 40 PSI
during peak day demands. Because of the proposed method of filling storage facilities
during high-stream flows for later use, the transmission lines for the ponds must be sized
adequately to transmit enough water during the high flow periods to fill the ponds as
intended. Needed pipeline projects that will benefit the system were determined using the
general outline below:
a) All new pipelines to serve new development were modeled as at least 8-inch.
b) All existing and new users were placed in the model to match the best available
information as to their locations and densities.
c) To estimate the peak flow during the peak days, an application rate of 1.5”-2” (2” was
used when modeling) per week recommended by WBWCD28 was applied to the acreage
identified in Table 1 – Active Users, 2020 on page 5 for each unit.
d) Areas of low pressure were identified and means to eliminate those areas of below-
standard performance were determined by modeling larger or additional pipelines until
the sub-standard conditions were eliminated.
e) Anticipated flow rates needed to fill the proposed ponds during an anticipated 45-day

E. Identify the means by which the political subdivision or private entity will meet those growth
demands29
There are multiple combinations of increasing source and storage capacities to maintain the
Annual Delivery LOS for future users. In this section, several of what now appear to be the most
probable methods of meeting buildout conditions are identified with their estimated present-
value cost of implementation. Following the discussion of how buildout demands can be met, a
proposed method for meeting near-term needs is presented…a 10-year plan to add Annual
Delivery capacity at the proposed LOS so that additional ERUs can be served by WCWSID. These
discussions of buildout and near-term projects are not intended to limit WCWSID in pursuing
different combinations or sequencing of methods to increase Annual Delivery capacity.
1. Water Rights
Build Out (315.78 AF additional need): WCWSID must have the right to divert water before
the Annual Delivery capacity can be increased, so increasing water rights is discussed first
and separately.
The following discussions of methods to increase WCWSID’s water right capacity also
include some discussions of increasing source and Annual Delivery capacities. Each of the
types of capacities are so interrelated that they are inseparable, but each method below
focuses first on a way to increase water right capacity and so is included in the Water Right
category below.
(1.a) “Municipalize” – There is an administrative need to “Municipalize”30 the
WCWSID-owned shares of WCIC so that the District can count AF of water
beneficially used rather than the number of acres on which that water is used. The
District anticipates that the professional fees to accomplish said change will be
$50,000 and would result in the involved shares allowing for the beneficial use of
the District’s proportionate share of the WCIC31.
o It is anticipated that this change will be pursued to a successful completion,
which would eliminate the acres-irrigated limitation and allow for full
utilization of WCWSID’s shares of the WCIC’s water rights.
o The physical water for this Municipalization process is immediately available
and no additional storage would be needed.
o Municipalization would not increase the flow of wet water into the District
and would therefore not benefit future users by supporting secondary

29 Reference: Utah State Code11-36a-302(1)(a)(v)
30 Municipalize is a term coined for this IFFP. It consists of filing a Change Application on the portions of water rights utilized by the WCWSID to
have those portions identified for a Municipal type of Use in the State Engineer’s database, because the District is a Municipal water provider.
31 As stated in Item IV.A.1 on Page 6, the base WCIC water right limits the District to the irrigation of 194.76 AC. At the 2020 average use rate of
2.00 AF/irrigated AC (see Table 2 – Secondary Water Use by User Type, 2020), the District’s owned shares are limited to (194.76 AC * 2.00
AF/AC) 389.52 AF. If the same shares are municipalized, the WCWSID shares of WCIC would allow the District to use up to the historical
diversion of 2.18 AF/share. As an example of the effect of municipalization: The District currently owns 207.66 shares of WCIC. At the historic
AF value of 2.18 AF/share, the District would have right to (207.66 shares * 2.18 AF/share) 452.70 AF. The effective increase in allowable AF (it
is important to note that converting to Municipal Type of Use would keep the water use of the District within the limits anticipated by the
water right) would be (452.70 AF – 389.52 AF) 63.18 AF. The concept of Municipalization would apply equally to shares of any irrigation
company.

Wolf Creek Water and Sewer Existing LOS Date: November 1, 2021
Improvement District PAGE 17 Last Saved: March 25, 2022
water use by additional ERUs. It is recommended that the District
undertake the process of Municipalization. The process is not impact fee
eligible and is included in this IFFP as a reminder for master-planning
efforts.
(1.b) Acquire additional WCIC shares. As stated in the District’s 2021 Culinary Water
System IFFP, it is estimated that the District will be able to purchase an additional
ten shares of WCIC in the planning horizon. The cost of purchasing the mentioned
WCIC shares is already factored entirely into the Culinary Water IFFP. Including a
purchase cost in this Secondary Water IFFP for the same shares would be a double
billing to development. The cost of purchasing additional WCIC shares is therefore
not included in this IFFP.
Acquisition of the mentioned 10 shares would provide up to an additional 21.8
AF/YR32 for the secondary water support of (21.8 AF per YR / 0.36 AF per YR per
ERU) 60.556 ERUs.
o Pursuing this method of increasing water rights capacity would also increase
source capacity and the need for storage capacity (additional storage is
discussed in 2.a, below), which, when constructed, would increase Annual
Delivery Capacity.
(1.c) Increase reuse of treated effluent (this could potentially provide up to 494.9
AF/YR). Application of treated effluent from the District’s wastewater treatment
plant is covered by the same water right that allows the District to supply culinary
water to its customers. If the water does not leave the District’s possession,
WCWSID has the right to treat and apply (reuse) this effluent as secondary water.
There is no capital cost associated with the water rights portion of this method of
increasing water rights for secondary use. The capital cost of acquiring the water
rights is covered in the culinary water IFFP. The annual fee paid to WBWCD for
reuse of the water under the acquired rights is not impact fee eligible.
o The number stated above as the possible incoming water is the anticipated
quantity of treated waste at buildout. The estimate is based on 2020
treated effluent volumes and 2020 residential users.
o During 2020, treatment plant SCADA records indicate that the 1,129
culinary ERUs33 produced 227.767 AF of treated effluent34. On average,
then, it is estimated that each culinary ERU results in the production of
0.202 AF of treated effluent during the year.

32 10 shares * 2.18 AF/share when “Municipalized” = 21.8 AF.
33 WCWSID culinary records indicate 549 multi-family, 565 single-family and 15 commercial active Units on Dec 31, 2020, the same year for
which treated effluent records were analyzed.
34 For reference, copies of these records are saved on the Gardner Engineering server at R:\2319 - Wolf Creek Water and Sewer\2103 - IFFP

Secondary Water System Impact Fee Facilities Plan IV-E - Identify how to meet demands
Wolf Creek Water and Sewer Existing LOS Date: November 1, 2021
Improvement District PAGE 18 Last Saved: March 25, 2022
o The District anticipates a total of 2,450 culinary ERUs at buildout35. At a rate
of 0.202 AF of treated effluent per culinary ERU per year, it is anticipated
that (2,450 ERUs * 0.202 AF/YR) 494.9 AF of treated effluent would be
produced each year at buildout.
 Changes in the percentage of year-round residents and seasonal
occupancy rates will influence the annual quantity of treated
effluent per culinary ERU, but the calculations above are a sound
basis for planning.
o Currently, treated effluent must be used at roughly the same rate it is
pumped into the secondary system because of limited storage capacity.
o If sufficient storage capacity is created to hold treated effluent when there
is not demand for it (i.e., create additional storage to hold the volume
between Oct. 1 and May 31 each year when there is little to no demand for
secondary water), the District could plan on the entire volume of treated
effluent, less seepage and evaporation36, for use in the secondary system.
o Based on the treated effluent production rate in 2020, it is estimated that
the current 1,16537 culinary ERUs would generate 235.33 AF of treated
effluent.
o Pond sizing, costs and benefits are discussed further in 2.a, starting on
Page 21, below.
(1.d) Add Wolf Creek channel as Point of Diversion (POD) on the water right exchange
contracted with WBWCD.
o Before 2013, the culinary and secondary water systems, which are now
owned and operated by WCWSID, were owned and operated by the private
Wolf Creek Resort (Resort). As a planning effort to meet the needs of future
residents, the Resort contracted with the Weber Basin Water Conservancy
District (WBWCD) for the right to divert 300 acre-feet (AF) of water for
Municipal use. The Resort reorganized under bankruptcy in 2013, and
WCWSID was organized as the public entity to own and operate the culinary
and secondary systems serving the area.
o In the shuffle of reorganization, the 300 AF contract expired.
o In 2018, the District recognized that the need for additional Municipal water
rights would be satisfied to a significant extent by the expired 300 AF

35 Note that this refers to the number of culinary ERUs at buildout. The landuse map adopted in each of the District’s IFFP’s identifies
something less than 2,500 units at build out, but for some factor of safety and convenience, the District has opted to plan for 2,500 culinary
ERUs at buildout.
36 Based on “Crop and Wetland Consumptive Use and Open Water Surface Evaporation for Utah”, Utah Agricultural Experiment Station
Research Report #213, August 16, 2011, Pine View NWS station, net evaporation expected from an average “deep” vs. “shallow” water body
(estimated average depth of 15’ in a future pond to capture treated effluent) is 15”/AC/YR. Estimated seepage loss from a pond with a liner
permeability of 1x10-7 cm/s or less is calculated to be 12”/AC/YR.
37 WCWSID culinary records indicate 555 multi-family, 594 single-family and 15 commercial active connections on Nov. 1, 2021.

contract. The District negotiated with WBWCD to pay $521,118.00 to
reinstate the contract, with WCWSID as the contracting entity. The District
currently has a water right exchange application in process of approval at
the Division of Water Rights, Number E6249, that will combine the 300 AF
contract with two others into a single 303 AF water right. It is anticipated
that 50% of the contracted water right will be used to help meet secondary
water needs, with the other 50% used to help meet culinary needs.
o The water right underlying the contract does not currently identify Wolf
Creek channel as a Point of Diversion.
 A change application must be submitted and approved to allow
diversion of water from Wolf Creek channel.
o It is estimated that the professional fees associated with effecting the
needed POD changes is $90,000.
o The water diverted from Wolf Creek channel under this right will be
available during periods of Wolf Creek flow greater than the WCIC high-
water right, 20 CFS.
 Because greater-than-20-CFS flows are only present for a relatively
short period of time in Wolf Creek (45 days in 201638) during the
spring when irrigation demands are low, 100% of the flow must be
captured in storage for use later in the season.
 Based on recorded flow data, an average 1.29 CFS above the 20 CFS
WCIC high-water right was available to the WCWSID for the 45 days
identified in 2016. A storage capacity of 115.14 AF39 would be
needed to entirely capture the recorded flow and is address in 2.a,
below.
(1.e) Add two new groundwater wells as Points of Diversion (PODs) on the water right
exchange contracted with WBWCD.
o It is currently anticipated that a new well will be constructed on land owned
by the District south of the 10-Acre Lake, which is discussed further in (g),
below.
o Another well at an as-yet undetermined location will also be constructed
and is discussed further in (g), below.
 The location of any well drilled under this right must first be
reviewed to determine if a change application would be needed to
add the well’s location as a point of diversion.

38 2016 is the most recent year for which total Wolf Creek channel flow is available. Subsequent years’ data available to Gardner Engineering is
for the WCIC’s diversion from the main Wolf Creek channel.
39 45 days * 1.29 CFS * 646,316 GPD per CFS / 325,851 GAL per AF.

Improvement District PAGE 20 Last Saved: March 25, 2022
· It is anticipated that such change(s) will be approved.
o It is estimated that the professional fees associated with effecting the
needed POD changes is $10,000.
The District has started the process of adding points of diversion to its water rights as
discussed. It is recommended that WCWSID continue these efforts.
(1.f) Purchase shares of irrigation companies with water in the Causey or Eden Irrigation
District Canals (Up to 10 shares for an additional 21.8 AF40). If shares in either of
these canal systems become available for purchase, it is anticipated that WCWSID
could purchase them and pump the purchased water into the WCIC system in
exchange for a greater percentage of Wolf Creek flow at the splitter, or as otherwise
agreed with the companies involved.
o Both the Causey and Eden Irrigation District canals cross Highway 158 in
Ogden Valley, a mile below the WCWSID system. The WCIC has a
pressurized main line that also crosses the canals at the same location.
o Rather than installing a pump line from the canal(s) up to WCWSID, it
appears feasible to pump water from the canal(s) into the WCIC pipeline in
exchange for an equal volume of water from the Wolf Creek diversion. This
would need to be coordinated with WCIC.
o A small pond constructed to hold water diverted from the canal system
would function as an intake basin for a pumping facility. It is anticipated
that a single pond, strategically placed, would be able to receive water from
one or both canal companies.
 The estimated cost to make the needed pond, piping and pumping
improvements is $864,500.
o Additional storage capacity would need to be constructed in the WCWSID
system to hold the additional Wolf Creek water that could be taken at the
splitter. Storage will be considered in 2.a, below.
o A change application on the owned shares should be filed to change the
Type of Use to Municipal so WCWSID could count AF used rather than acres
served.
 It is estimated that the professional fees for the mentioned change
application would be $10,000 per company, for a total water rights
cost of $20,000.
 The estimated share cost is $25,000 per share, with each share
having an AF-value estimated at 2.18 AF per share.

40 Arbitrary number of available shares at an AF-value per share equal to the historic AF-value of WCIC shares. The assigned AF-value has not
been vetted to any extent and may be different than stated here.

Improvement District PAGE 21 Last Saved: March 25, 2022
 The availability of shares is highly variable in terms of frequency and
quantity. It is arbitrarily estimated that 10 shares of canal company
stock will be available for purchase by the end of 2030.
 Thus, an estimated $250,000 would be paid for 21.8 AF of canal
company water, which would meet the secondary demands of 60
ERUs.
2. Annual Delivery
Subtopic 1, Water Rights, immediately preceding, focused on methods to obtain more water
rights for use in the secondary system. The following discussions of how to increase storage
to capture and fully utilize the increased diversions mentioned above, complement the
increases in water rights to increase WCWSID’s Annual Delivery capacity.
2.a Construct additional storage to complement the water rights method:
2.a (1.a) Municipalize WCIC shares.
o Municipalization will not contribute to the need for additional storage.
2.a (1.b) Acquire additional WCIC shares.
o It is anticipated that the additional water made available through the
purchase of additional shares of WCIC would be diverted at the splitter and
used in the secondary system in the same manner as the water from the
current WCIC shares.
o It is expected that the ratio of available storage at present for the current
number of ERUs would continue to provide adequate storage for utilization
of future shares of WCIC. Thus, the District would need to construct
additional storage at the rate of 0.06 AF/ERU to fully utilize the additional
water made available through purchase of WCIC shares.
o At a rate of 0.06 AF/ERU, and an estimated 60 additional ERUs that could be
supported with the water purchased with 10 shares of WCIC, 3.6 AF of
storage would be needed to fully utilize the water delivered via purchase of
additional WCIC shares.
2.a (1.c) Increase reuse of treated effluent.
o Treated effluent is already being produced. Currently, the treated effluent
is reused from approximately June 1 through September 30 by pumping up
to the pond on the 9th hole and then pumping it into the District’s irrigation
system.
o From October 1 through May 31, when there is no irrigation demand
sufficient to warrant pumping treated effluent for reuse, the District
currently disposes of treated effluent in rapid infiltration basins at the
District’s wastewater treatment plant.
Secondary Water System Impact Fee Facilities Plan IV-E - Identify how to meet demands
Wolf Creek Water and Sewer Existing LOS Date: November 1, 2021
Improvement District PAGE 22 Last Saved: March 25, 2022
o Note that if 235.33 AF of treated effluent is produced each year41, and if the
recent average diversion for reuse on the golf course continues, an
estimated (235.33 AF produced – 35.4 AF used42) 200 AF could be sent to
storage during the non-irrigation season for use during the irrigation season
given the current number of culinary ERUs.
o The District is contemplating the immediate construction of a 90 AF “Bridges
Pond” to store treated effluent produced during low-irrigation-demand
times of the year.
o The conceptually-designed 90 AF Bridges pond has an estimated wetted
footprint and surface area of 6.1 AC. When full, it is estimated that seepage
and evaporation losses from the pond will be 13.7 AF/YR43.
 It is recommended that any new storage pond be constructed with
a lining system44 that has a permeability no greater than 1x10-7
cm/s.
o It is anticipated that treated effluent from the current number of culinary
ERUs could fill the 90 AF Bridges Pond in five months45 during non-
irrigation-demand months of the year.
o Any amount treated beyond the capacity and use of the Secondary system
(including losses due to seepage and evaporation) would be sent to the
rapid infiltration basins at the treatment plant.
o It is recommended that the District immediately construct a large pond to
store treated effluent. The pond, pumping facility and transmission line to
move the treated effluent to the Bridges Pond would primarily benefit the
secondary system, but would also provide a redundant method for treated
effluent disposal.
 It is appropriate that the cost of the pond, pumping facility and
transmission line be shared between the Secondary System and the
Sanitary Sewer system. The estimated benefit to each system
would be 90% benefit to secondary and 10% benefit to sanitary
sewer.
· The Secondary portion of the cost would be 100% impact

42 Reference Table 3 – Average Secondary Water Supply (AF), 2015-2021 on Page 6.
43 Refer to evaporation and seepage estimates in Footnote 36, where a loss rate of 27” (2.25’ in terms of feet) per pond AC per year is
estimated. 2,25’ * 6.1 AC = total estimated losses.
44 A lining system will be determined during pond design and may include soil amendments, HDPE liners, seepage retrieval well(s) or other
technology.
45 Estimated as Pond volume (90 AF) plus some number of months of losses (13.7 AF *x months/12 months per year) is the volume of treated
effluent needed to fill the pond. It is estimated that the treated effluent from the current 1,165 ERUs at a rate of 0.202 AF/YR per culinary ERU
would fill the 90 AF pond in approximately 5 months (solve for x in the equation: 90 AF + (13.7 AF * x months/12 months per year) = x months *
(1,165 ERUs at 0.202 AF per year / 12 months).

maintain the current Annual Delivery LOS, which is the
proposed Annual Delivery LOS as stated in Table 11 –
Proposed Annual Delivery LOS on page 11.
· The Sanitary Sewer portion of the cost is addressed in the
Sanitary Sewer IFFP.
o The construction of the conceptually planned 90-AF pond on developer-
owned ground in the western portion of the District, known as the Bridges
Pond would enable the District to collect treated effluent during winter
months for application during summer months. It is estimated that
construction of the 90-AF Bridges Pond, including pumping facilities and
transmission line from the treatment plant would cost an estimated $57,000
per AF.
 Detailed estimates of construction for the Bridges Pond and reuse
line are included in Appendix B.
2.a (1.d) Add Wolf Creek channel as Point of Diversion (POD) on the water right
exchange contracted with WBWCD.
o At present, early-season flows from the Wolf Creek Diversion largely flow
through the WCWSID system when there is minimal irrigation demand and
the District’s storage facilities are already full.
o The benefit to Annual Delivery Capacity by implementing this method would
be equal to the volume of storage constructed for this purpose, up to the
volume of water that is currently overflowing the system for use throughout
the season, an estimated 99.4 AF46.
o It is recommended that WCWSID pursue additional storage capacity first by
relining its Highland Pond. The original pond liner is insufficient to hold
more than 10.0 AF of the pond’s 19.9 AF geometric capacity. It is estimated
that relining the pond would add 9.9 AF to the District’s storage capacity.
 Since the water to fill the added pond capacity would be coming
from early season flows and would be one-time storage rather than
equalization storage during the irrigation season, the number of
ERUs supported by the added volume would be calculated by
dividing the added storage capacity by the full annual demand per
ERU.
· 9.9 AF / 0.36 AF annual demand per ERU = 27 ERUs.

46 Refer to the paragraph below Table 7 – Source Capacity on Page 8. Note that the 484 AF was measured in to WCWSID from Wolf Creek at the
splitter. Because of insufficient storage, there was flow-through. Other losses (seepage, leaks and evaporation) also occurred to an unknown
extent. For the purposes of this IFFP the “other losses” will be considered as part of the flow-through volume. Because of flow-through, 35.4 AF
of treated effluent had to be pumped into the system to meet users’ demand for 420 AF during lower-flow times of the year. The quantity of
flow-through is calculated as the difference between what was used from Wolf Creek (420 AF used – 35.4 AF added from treated effluent =
384.6 AF) and what was supplied from Wolf Creek (484 AF): 484 AF – 384.6 AF = 99.4 AF.

 It is estimated that relining the Highlands Pond would cost
approximately $42,000 per AF. A detailed estimate of construction
cost of relining the Highlands Pond is included in Appendix B.
o The resulting capacity increase from relining the Highlands Pond would be
relatively small, so it is recommended that the District also immediately
pursue the construction of a larger pond. Construction of the conceptually
designed Retreat Pond on the District-owned parcel on the bench above the
existing Primary pond would increase the District’s storage capacity by 52-
AF47. It is estimated that construction of the Retreat Pond would cost
approximately $54,500 per AF. A detailed estimate of construction cost of
the Retreat Pond is included in Appendix B.
 The Retreat Pond would be filled by pumping un-demanded flows
from the Primary Pond for a short time during the high-flow
months. The Retreat Pond would then provide an additional source
of gravity-fed water throughout the remainder of the irrigation
season.
 The Retreat Pond is ready for immediate design and construction
because WCWSID owns the property on which the pond would be
built.
 Since the water to fill the Retreat Pond would be coming from early
season flows and would be one-time storage rather than
equalization storage during the irrigation season, the number of
ERUs supported by the added volume would be calculated by
dividing the added storage capacity by the full annual demand per
ERU.
· 52 AF / 0.36 AF annual demand per ERU = 144 ERUs.
2.a (1.e) Add two new groundwater wells as Points of Diversion (PODs) on the
water right exchange contracted with WBWCD
o The District has purchased property south of the 10-acre Lake on which to
drill a well. A test well was drilled in 202048 which indicated that a
production well in the same general location may be a significant source for
the secondary water system, and partially recover seepage from the 10-AC
Lake. The water right to allow diversion from such a well was discussed in
Item (1.d), starting on Page 18.
o Another well at an as-yet undetermined location will also be constructed as
needed to meet the District’s demands.

47 52 AF is the optimal capacity of a pond conceptually designed on District-owned property on the bench above the Primary Pond, given terrain
constraints and the desire to limit cut and fill volumes.
48 Surrey Ridge Well #1, known as S.R.-1, drilled at a cost of $30,000.
Secondary Water System Impact Fee Facilities Plan IV-E - Identify how to meet demands
Wolf Creek Water and Sewer Existing LOS Date: November 1, 2021
Improvement District PAGE 25 Last Saved: March 25, 2022
o It is estimated that construction of new secondary wells will cost $300,00049,
will produce 50 GPM, would require 1.123 AF50 of constructed storage for
the benefit of 18.72051 additional ERUs each.
2.a (1.f) Purchase shares of irrigation companies with water in the Causey or
Eden Irrigation District Canals
o Local storage at the point of diversion from the given canal would be
needed. It is anticipated that a 3 AF pond will be sufficient to hold nearly 2
weeks of turns52. It is further anticipated such a pond located near Highway
158 where both canals are in close proximity could serve as the receiving
pond for water from either or both canal companies simultaneously. The
estimated cost of local storage and associated piping and pump
improvements is $864,500 (refer to Page 19), the development of which
cost is included in Appendix B.
o It is expected that purchase of water in these canal companies would result
in pumping the purchased water into the WCIC system, in exchange for
additional flow through the flume that splits the Wolf Creek channel flow to
WCIC and WCWSID.
o It is expected that the current amount of storage in the system for flow
from the splitter would continue to be adequate, 0.06 AF per ERU (refer to
Table 8 – Storage Capacity on Page 9), for a total storage need in the
system of 3.6 AF53 to complement purchase of company shares.
3. Distribution
(3.a) Construct new transmission lines and pumping facilities as determined by the
method chosen to increase Annual Delivery capacity.
o The methods and projects to implement each method will determine which
transmission lines and pumping facilities will be needed. The cost of
transmission lines and pumping facilities is included in the cost estimate
development for each method. See the attached map in Appendix A for a

49 $30,000 exploration cost for the test well that was drilled in 2020, plus an estimated $50,000 for professional and design fees, plus an
estimated $100,000 for construction of a production well, plus an estimated $120,000 for equipping and tying the well into the irrigation
system. It is intended that the collected fees be used on costs related to construction of the well regardless of whether the costs are related to
the tasks suggested in this estimate.
50 Estimated storage calculated as the current amount of storage provided per ERU (0.06 AF/ERU) multiplied by the number of ERUs supported
by each well (18.720 ERUs).
51 This assumes new wells with a production of 50 GPM each well would pump June-Sept. for an average of 6 hours per day, which would put
6.739 AF over the course of the irrigation season into the system for use. With the P-LOS of 0.36 AF/YR/ERU, (6.739 AF/YR / 0.36 AF/YR/ERU)
18.720 ERUs can be supported.
52 It is assumed that each share represents 3 CFS for 45 minutes each 7.5 days. Ten shares would be equivalent to 10 shares * (3 CFS/turn *
448.8 GPM per CFS * 45 min/turn) / 325,851 GAL/AF = 1.859 AF each 7.5 days. Estimated flow is speculative. An interview conducted by
Gardner Engineering with an Eden Irrigation Co. shareholder on Dec. 21, 2021, resulted in no flow estimation being given. The interviewee’s
response to the question of how much flow is associated with a share of the Company was “You get a turn every 7 days and 6 hours and how
much flow depends on which ditch and where on the ditch the water is being pulled from.”
53 Ten shares could support the Annual Delivery needs of 60 ERUs as determined on Page 19; 60 ERUs * 0.06 AF/ERU = 3.6 AF of storage.

visual representation of facilities needed to support and make
implementation of the various methods possible.
Tables B3 and B4 in Appendix B summarize the estimated costs and potential benefits of the
discussed methods for increasing Annual Supply capacity in WCWSID. The tables summarize
ways in which the buildout number of ERUs can be supported. They shows that it is possible for
WCWSID to meet irrigation demands at buildout; a toolbox, per se, with the best method, or
tool, available at the time it is needed, being used to meet the District’s needs.
For illustration purposes and not to imply any commitment on the part of the District, if
WCWSID develops sufficient Annual Delivery capacity in the secondary system, and sufficient
Source Delivery capacity in the culinary system to allow removal of restrictions on Can and Will
Serve letters for building permits for inactive ERUs by the end of 2022, it is estimated that 344
additional culinary ERUs54 would be active on the system by the end of 2030. It is anticipated
that the type of new culinary ERUs would be approximately 50/50, Single-family to Multi-family.
When converting to secondary units (refer to Table 4 – Equivalent Residential Unit Definition
and User Type Comparison on Page 7), it is anticipated that approximately (172 Single-family at
1 ERU/unit and 172 Multi-family at 0.36 ERUs per unit) 234 secondary ERUs would be added to
the secondary system by the end of 2030.
There is a significant gap between buildout conditions and the present state of the WCWSID
secondary system. The following table presents a proposed first step towards increasing Annual
Delivery capacity, such that the proposed LOS is maintained and additional ERUs can be added
to the system. It is imperative to development that the District increase Annual Delivery
capacity, because at present there is no excess capacity to serve additional ERUs.
A table of estimated costs and benefits for each of the methods, (1.a) through (2.a) of increasing
Annual Delivery capacity is included in Appendix B. A recommended course of action for the
next planning period and the estimated costs associated with each method is given in Table 19 –
Recommended Improvements to Increase Annual Delivery Capacity, 2022-2030 on the following
page.

54 Phone conversation with Annette Ames, WCWSID office manager, 2020-09-01. 2016 = 23 added units; 2017 = 12 single-family + 14 Bridges +
24 Mountainside Phase 1; 2018 = 40 Retreat + 16 Eden Escapes; 2019 = 43 added units. This is an average of 43 ERUs per year. If an average of
43 ERUs were connected (it is recognized that the referenced units were not physical connections, but for illustration, it is estimated that the
rate of physical connections sans moratoria would mimic the rate of added units issued in the 4 years prior to establishment of any moratoria)
in each of the 8 years from 2023 through 2030, 344 connections would be made in the planning horizon.

(1) Required storage per ERU was estimated as the existing
amount of storage provided to each ERU, because the
additional flow from the Wolf Creek splitter provided by
this option would enter and be used by the system at the
same time of year as the flow currently coming in from the
splitter.
(2) This quantity of additional reuse is the total estimated
treated effluent at buildout (Page 16, last bulleted
paragraph), less the historic average reuse (Table 3 on
Page 5).
(3) The cost of the water rights for reuse is the annual
contract maintenance charge for the culinary water that
provides the sewage to treat plus the annual contract fee
that WBWCD charges for reuse of treated effluent. The
cost to produce the treated effluent is an operational cost
covered by sewer fees. None of these fees are impact fee
eligible.
(4) All of the water obtained through this water contract
change would come during spring flows when there is
minimal demand on the irrigation system, so 100% of the
diverted water would need to be stored for use later in the
season.
(5) This quantity of storage was estimated by multiplying
the existing amount of storage provided to each ERU by
the number of supported ERUs (0.06 AF/ERU * 37 ERUs),
because the additional flow from the developed wells
would be put into the system on an as-needed basis and
minimal storage will be needed for adequate operation.
