Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
SGM #01501C-173 1
1. BACKGROUND AND INTRODUCTION
Since 1983, the Mid Valley Metropolitan District (MVMD) has been expanding its
service area as growth occurred within the service area. It also expanded its service area
to include two developments that were located next to the District’s existing service area,
but were in Garfield County. The District’s original master plan intended that the District
provide water service to both the existing service area, which is much larger now than
when the district was created, and an extended service area. However, the previous water
master plan did not consider the level of development currently being contemplated
within the District.
As a result, the District’s existing water infrastructure needs to be evaluated to ensure
sufficient water supply, water storage and fire flow availability now and into the future.
This Water System Master Plan (WMP) contains recommendations for MVMD to serve
the existing service area and proposed growth. This WMP will help and assist MVMD in
achieving a reliable, efficient, and effective water system. Study objectives include the
following:
1. Evaluate the following existing water system infrastructure elements to determine if
shortcomings exist:
x Water Supply – Determine if current water supply and production facilities are
adequate to meet demands.
x Storage Volume – Determine if existing storage capacity is sufficient to meet
required storage volumes.
x Reliability – Evaluate system reliability or redundancy to determine what
modifications could be made to improve the delivery of water to the users.
x Fire Flow – Evaluate distribution system’s ability to deliver target fire flows.
Fire flow requirements have changed significantly since the District was created.
As stated in the latest version of the International Fire Code and verified by the
District’s Fire Chief, 4,000 gallons per minute for a duration of four hours is
required for the larger commercial uses in the District. This includes a 50%
reduction in fire flow due to the presence of a sprinkler system in the building.
2. A variety of possible growth scenarios face MVMD. These include the buildout of
existing developments within its service area, potential new developments both inside
and outside existing District boundaries, and the potential for the Crawford property
to be serviced by MVMD. This master plan identifies the extent and locations of
new development units, associated water demands for each of these growth scenarios
and the required infrastructure to service them. In addition to the four evaluated
items mentioned above, this WMP addresses the need for new distribution mains to
serve potable water to new developments by considering the locations and size of
each potential tie-in.
1.1 Existing System Overview
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
SGM #01501C-173 2
The existing water distribution system layout can be seen in Exhibits 1 & 2, which
illustrate:
x Water storage tanks
x Wells
x Pressure zones
x Pressure reducing valves (PRVs)
x Booster pump
x Transmission and distribution mains
Storage Tanks: There are currently three water storage tanks within the District. The full
capacity of the existing Blue Lake tank cannot be utilized due physical limitations as
shown in Table 6. This Table shows there is a height discrepancy between the tanks,
which limits the overall water level in both the BLM and Blue Lake tank to 26’ with a 1’
buffer below the overflow.
x Blue Lake Tank - 0.75 MG capacity on Zone 1
x Bureau of Land Management (BLM) Tank - 0.50 MG capacity on Zone 1
x Aspen Junction Tank - 0.06 MG capacity on Zone 3
Wells: There are currently five wells in service and three not in service within the
District:
x Wells pumping directly to Blue Lake tank
o Well 1 - 75 gallons per minute (GPM)
o Well 2 - 400 GPM
o Well 8 - 500 GPM
x Wells pumping directly to BLM tank
o Well 3 - 250 GPM
o Well 4 - 120 GPM
x Total well production capacity - 1345 GPM
x Wells not in service
o Cerise Ranch
Juniper Well – 25 GPM
Willow Well – 35 GPM
o Basalt Industrial Park
Well – 20 GPM
Pressure Zones: There are currently three pressure zones within the District. Pressure
zones are used to maintain pressures within a target range and are separated by PRVs and
pump stations. The four zones are Zone 1, Zone 2, Zone 3 and Zone 4. Zone 1 pressure
is controlled by the water surface elevation in the Blue Lake tank and BLM tanks. Zone
2 pressure is controlled by a PRV that ties into the transmission main from the Blue Lake
tank. This zone controls the pressures in Blue Lake, Dakota and Cerise Ranch. Zone 3
pressure is controlled by the water level in the Aspen Junction tank, which is filled by a
booster pump connected to the transmission main from the BLM tank. Zone 4 is a sub-
zone of Zone 3 and is controlled by a PRV.
PRVs: As mentioned in the Pressure Zone section, PRVs are used to control the pressure
within the system. There are two currently being used; one controls the pressure for Zone
2 and the other controls the pressures in the zone of Zone 4.

SGM #01501C-173 3
Booster Pump: A booster pump is used to lift water from a lower pressure zone to a
higher one. The booster pump in this system helps maintain the tank level in the Aspen
Junction tank, which establishes Zone 3 pressures. The capacity of this pump is 30 gpm.
Transmission & Distribution Mains: These are the water mains that deliver water from
storage tanks and production sources to the users. Transmission mains are 12 inches and
larger and distribution mains are normally smaller than 12 inches.

2. DEVELOPMENT SCENARIOS
This study considers four development scenarios for the MVMD water system as defined
below. A breakdown of the equivalent residential units (EQRs) for each scenario can be
found in Table 1.
2.1. Scenario 1
This scenario represents existing development, water demands and infrastructure
conditions for the MVMD water distribution system. It provides a baseline from which
to measure projected growth. Existing demands and system infrastructure are based on
analysis of 2005-2008 water meter records, water production records and available as-
built information for existing developments. EQR totals for Scenario 1 were established
based on analysis of MVMD’s water billing database and only reflect taps currently using
water. They do not include construction taps. The total existing EQRs in the system, as
of April 2008, were established to be 1,453. The developments included in this scenario
can be found in Table 1.
2.2. Scenario 2
This scenario represents full anticipated buildout of the existing developments plus
miscellaneous infill to account for small developments not currently in the planning
process and the possibility of higher densities within the existing District boundaries.
The developments included in this scenario in addition to those in Scenario 1 are Arlian
Ranch, Fitzsimmons, KOA, and Vaugner. The total EQRs for this scenario were
established to be 2,760. Exhibit 4 shows the location of the proposed developments.
2.3. Scenario 3
This scenario includes the development projected under Scenario 2 plus the buildout of
future anticipated developments outside of the existing service area. The estimated EQRs
for this scenario were established to be 3,742. The developments included in this
scenario in addition to those in Scenario 2 are Ace Lane Property/Kodiak Ski Lake,
Aspen/Basalt Trailer Park, Basalt Bluffs, Clifford Cerise, Glassier Property, Guy
Property, Kennel Property, Shelton Property, Sopris Village and TCI Lane Ranch.
Exhibit 1 shows the location of the proposed developments.
2.4. Scenario 4
Scenario 4 represents the most significant growth scenario considered in this WMP. It
includes the development identified to be served under Scenarios 2 and 3 plus the
addition of the Crawford property to the District’s service area. This additional property
will most likely include an existing trailer park, commercial development (both existing
and proposed) and medium density residential development. The total EQRs for this
scenario were determined to be 4,267. Crawfords is the only additional development
modeled in this scenario in addition to those in Scenario 3. Exhibit 4 shows the location
of the proposed development.

3. WATER DEMANDS AND SUPPLY
An analysis of historical water production and billing data was conducted to establish
existing and project future demands. Assumptions were made concerning the existing
water demands for the District due to missing billing data. This was due to a meter
exchange program that was implemented in 2007-2008 to make readings faster, easier
and more accurate. While this program has been a huge success, it has led to incomplete
billing records for some MVMD customers.
Water billing records for customers grouped by development from March and April of
2008 were reviewed. This allowed the exact number of EQRs within the District to be
determined and the average day demand (ADD) per EQR for each development to be
calculated. By analyzing seasonal usage trends from 2007, the usage for the entire year
in 2008 was projected. A 5% increase in water usage was assumed from 2007 to 2008
based on monthly production data record comparisons.
Maximum day demand (MDD) drives the capacity needed for many water system
components. To determine MDD, daily water production data were evaluated to
determine a peaking factor, the ratio between MDD and ADD. This peaking factor can
be used to project future MDD values based on ADD projections. For this study, MDD
values are not available for individual developments. Therefore, MDD planning values
for each development were based on the application of a system-wide peaking factor to
projected ADD values for each development. The average peaking factor for the District
between 2005 and 2007 was 2.15.
The billing records for March and April of 2008 were compared with the well production
records for the same time period. The calculated non-revenue water values for March
and April were 49% and 38%, respectively. Table 2 shows the billed usage for each
month compared to the production volumes. While reducing system wide non-revenue
water would likely reduce the need for future infrastructure improvements and possibly
water supply needs, more information is required to reach a definitive conclusion due to
the limited billing data available for this analysis. The District should continue to
compare total monthly billing and production volumes to confirm the magnitude of non-
revenue water.

For the potential future developments, an average demand of 350 GPD/EQR was
assumed based on an analysis of current water production and EQR data. While this
assumed demand is currently less then the ADD shown in Table 2, it is an accurate
representation of expected future ADD for two reasons. First, due to several current
users with high GPD/EQR values, the system wide average is inflated as shown in
Appendix A. The District should evaluate their current assigned EQR value and adjust if
necessary. Second, when these users are removed from the system wide average it is
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 8
reduced to 320 GPD/EQR, which is an average of commercial, residential and light
industrial demands.
A 2.15 MDD to ADD peaking factor was also assumed for all future EQR water demand
projects as these developments were assumed to use treated water for irrigation.
However, if the anticipated developments rely on raw water irrigation, the peaking factor
could be reduced.
It should be noted that observed average and maximum day demands could be reduced in
the District by the following methods:
x Identify and control non-revenue water
x Use raw water for irrigation
x Implement steeper inclining block rate structures
x Provide incentives for customers to implement various water conversation
measures
x Implement broad water conservation programs
x Educate users on efficient water use principles
3.1. Water Demand – Scenarios 1 - 4
Appendix A contains unit demands (ADD and MDD per EQR) for all scenarios. The
existing and assumed system wide average water demands can be seen in Table 3.
Table 3 System Wide Averages and Water Demands for Scenarios 1 - 4
Scenario Demand Type Unit Demand
(GPD/EQR)
Total Demand
(MGD, GPM)
Average Day 501 0.7 (486) Scenario 1 Maximum Day 1077 1.4 (964)
Average Day 490 1.0 (711) Scenario 2*
Maximum Day 1054 2.2 (1528)
Average Day 462 1.4 (956) Scenario 3
Maximum Day 992 3.0 (2055)
Average Day 459 1.6 (1084) Scenario 4
Maximum Day 987 3.4 (2330)
*For existing developments that have not reached full buildout, the average demand for
that development as determined in Scenario 1 was used to project future demands. As
most of the lot sizes for these developments will remain constant, this is an accurate
assumption. A demand of 350 gpd/eqr was only applied to developments not in the
construction stage. However, in the case of Shadowrock, which is currently completing
its first phase and has a limited amount of users, a demand of 350 GPD will more
accurately reflect the development’s usage at full buildout.
3.2. Existing Water Supply
MVMD’s existing potable water sources are five groundwater wells (Exhibit 3). Wells
number 3 and 4 are located in the southeast portion of the existing District near Oak
Grove Townhomes and Basalt Trade Center. Wells 3 and 4 have water rights for
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008

SGM # 96059A-92 9
approximately 400 gallons per minute (GPM) or up to 215 acre-feet a year. Normally
Well 3 produces 250 gpm and Well 4 produces 120 gpm. These wells typically operate
only during the months of May to September due to ground/static water levels in the
wells. The water level varies because of the seasonal ground variation of the water table
which may be tied to the operation of the Robinson Ditch. Seasonal production
limitations have not posed a problem for the District historically because they are not
needed to meet non-irrigation season demands. However, the Robinson Ditch is
scheduled to be lined in 1 year, so this could pose a serious problem.
There are also three wells located to the south of the Blue Lake developments just east of
MVMD’s wastewater treatment facility (WWTF). The three wells are numbers 1, 2 and
8 and have water rights for 400 (215 acre-feet), 250 (107.5 acre-feet), and 800 gpm (847
acre-feet) respectively. Normally Well 1 produces 400 gpm, Well 2 produces 75 gpm
and Well 8 produces 500 gpm. These wells produce water throughout the year and are
the main wells for the District. Relevant well information and pumping capacities are
provided in Table 4. Resulting demand versus production capacity is then shown in
Table 5.

Total 1345
The total production capacity shown in the previous table is sufficient to meet the
demands of Scenario 1. However, the existing firm capacity, which is the capacity of the
system when the largest well is offline, is not able to meet projected demands. As shown
in Table 5, the firm capacity in all scenarios is not adequate to meet maximum day
demand. Supplemental water production capacity is recommended to ensure reliable
delivery to meet peak demands.

The previously mentioned, Cerise Wells and Basalt Industrial Park Well are not in-
service due to a lack of infrastructure and/or equipment that is not compatible with the

current water system. It would be beneficial to verify the well’s pumping capacity and
static ground water levels if it is decided to bring them online. The pumps would also
need to be upgraded because their design was based on a water supply infrastructure that
is different than the current system.
3.3. Alternatives for Additional Production Capacity
Several options exist for increasing MVMD’s water production capacity. They are
described below.
Install new well(s)
MVMD could supplement its existing water supply by constructing new wells at
currently decreed sites. These decreed well sites are located in proximity to the existing
well sites (see Exhibit 3) and for modeling purposes can be assumed to tie-in to the
associated 8-inch supply lines for the existing tanks. This WMP also reviews the effect
of locating well/s on a site that is not within one of the existing well clusters. While this
option may require additional water court action and testing to verify well yields, it may
help improve system reliability.
Existing water rights are available to bring additional wells online at this time. However,
it may be necessary to change the point of diversion associated with the existing
rights/decreed wells due to the piping of Robinson Ditch.
Introduce potable water conservation practices
MVMD currently does not have potable water conservation measures and programs in-
place to help minimize existing and future water supply requirements. Some practices
include restricted watering, low flow fixtures, a more aggressive tiered rate structure and
public education. It may also be possible to minimize potable water demand in some
developments through introduction of raw water irrigation.
Control of non-revenue water in the system
MVMD non-revenue water may be as high as 38 to 49% according to Table 2 and
amounts to approximately 190 to 246 gpm, which is based on ADD for Scenario 1. Non-
revenue water is typically caused by leaks in the system, non-metered connections, etc.
Reducing this non-revenue water could significantly reduce water demands and future
infrastructure requirements.
For example, reducing the non-revenue water from 38% to 15% changes the firm
production capacity required for each scenario to those shown in Table 6. It should be
noted that the proposed demands for Scenarios 2-3, which is estimated at 350 gpd/eqr, do
not have the 23% reduction in water applied. This is due to reduced leakage and non-
metered water that is prevalent with new construction.

4. WATER STORAGE
Section 4 presents an analysis of MVMD’s water storage capacity.
4.1. Existing Storage Summary
MVMD currently maintains three water storage tanks that have an operational storage
capacity of 1.11 MG, which assumes a max operating level of 26 feet in each tank and a 1
foot buffer below the BLM tank overflow elevation. Relevant tank information is
provided in Table 7.

4.2. Storage Requirement Summary
Theoretical maximum storage volume required for the system is the sum of three
components: equalization volume, fire flow volume, and emergency volume. They are
described as follows.
Equalization Volume: The volume required to equalize the difference between the
system’s peak hour demand and its maximum day demand for a period of 6 hours. For
this study, the peak hour demand is estimated at two times the maximum day demand.
Fire Flow Volume: This is the volume required to supply the maximum fire flow to the
system for a specified duration, depending on building size, type and classification. For
this analysis, fire flow volume requirements are based on the following structures.
x All Scenarios – Residential Buildings
o 1,000 gpm for 2 hours when sf of building is less than 3,600
o 1,500 gpm for 2 hours when sf of building is greater than 3,600
x All Scenarios - Commercial
o Willits Commercial Buildings
¾4,000 gpm for 4 hours (assumed 50% flow reduction for
sprinkler system)
o Crawford Commercial Buildings
¾3,000 gpm for 3 hours (assumed Type IIA construction)
x All Scenarios – Light Industrial/Commercial
o Basalt Industrial Park

amount of fire flow depends on building size)
Emergency Volume: Emergency volume is that required to provide water to the system
when water production is curtailed. This may be due to rupture of a transmission line,
power failure or pumping failure. Assumptions for deriving this value vary, but typical
estimates assume that this volume should be sufficient to supply enough water to the
system to meet average day demand for a 24-hour period.
Table 8 provides a summary of theoretical water storage required for each scenario using
the above assumptions. Hydraulic modeling was conducted to confirm that additional
storage is not required due to water transmission constraints and that sufficient water
level fluctuations can be achieved operationally to turn tank contents over on a regular
basis.
Existing available storage volume for Zones 1 & 2 is based on a maximum water level of
22.5 feet in the Blue Lake and BLM storage tanks, which is set by the existing pump
controls for Wells 1, 2 and 8. The existing tank and well pump controls are shown in
Appendix B. Consequently, the maximum storage for Zones 1 & 2 is approximately
0.92 MG and Zone 3 is 0.05 MG. If the set points for the wells pumps were changed to
those shown Appendix B, then the maximum water storage volumes for the Blue Lake
and BLM tanks would increase to 1.06 MG. The Aspen Junction tank maximum storage
volume would increase to 0.06 MG.

5. SYSTEM ANALYSIS
Hydraulic modeling of the MVMD water distribution system was conducted as part of this
study to achieve the following goals.
x Identify current infrastructure shortcomings for each of the scenarios.
x Propose infrastructure solutions to the identified shortcomings in each scenario
x Determine hydraulic implications for each of the scenarios and how they affect the
system.
x Determine if a new pressure zone is required for the anticipated developments to the west
of the current District limits.
x Evaluate the locations of future water storage tanks to meet increased demands and
determine the best possible location/s.
x Determine if adequate system reliability is present in the current system and evaluate
future extensions and their effects on the system.
In evaluating the applicable options associated with each scenario, a set of analysis criteria is
provided below.
1. Maximum Pipe Velocity: The maximum pipe velocity is a critical element in maintaining
infrastructure longevity. High pipe velocities cause undue wear on elbows and fittings if they
occur continuously. High pipe velocities can be reduced by increasing pipe size or providing
additional flow paths. For this study, pipe velocities are evaluated under predicted maximum day
and peak hour demand conditions with the appropriate well pumps turned on. The recommended
maximum pipe velocities are as follows:
x Maximum Day Demand (existing infrastructure) < 7 ft/s
x Maximum Day Demand (future infrastructure) < 5 ft/s
x Peak Hour Demand < 10 ft/s
2. Optimum System Pressure: Distribution system pressures must be managed for several
reasons. The amount of water lost through leaks increases with increased pressure. Furthermore,
high pressures result in wear on the connection points in the system and may reduce the
infrastructure longevity. In contrast, low system pressures can lead to customer complaints due to
an inability to run irrigation systems and the potential to allow backflow, increasing the
possibility of system contamination. Minimum system pressures are evaluated under Maximum
Day Demand (MDD) conditions with pumps turned off, while, maximum system pressures are
evaluated under ADD conditions with pumps turned on. Minimum pressures are also considered
under MDD plus fire flow conditions. Optimum pressures vary, but for this study, the criteria are
as follows.
x Minimum system pressure = 40 - 50 (ideal) psi
x Maximum system pressure = 120 psi
3. Water Storage: Optimized water distribution system storage facilities not only provide
sufficient storage volume defined in Table , but also encourage mixing and turnover to minimize
water age. This helps to reduce stagnation in the tank, which can lead to water quality concerns.
The water age in the tank is calculated as the average tank volume divided by the average volume
added per day. This criterion is evaluated under average day demand conditions, with pumps
allowed to cycle normally. The target value as follows:
x Water Age < 7 days
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 14
4. Fire Flow Available: Fire flow delivery rate is also an analysis criterion. Undersized pipes
and limited conveyance pathways reduce the available fire flow to a given location. Fire flow
analyses are performed under MDD conditions assuming that tanks are only ½-full and water
production sources are off. Furthermore, maximum fire flow to each model node assumes that
the residual pressure at the node is not less than 20 psi and the pressure elsewhere in that zone
does not drop below 10 psi. At a minimum, 1,000 gpm is needed for a residential structure under
3,600 square feet and 1,500 gpm is needed for non-residential structures of construction types IA,
IB, IIA, IIB, IIIA, IIIB, IV, V-A and V-B. However, in specific locations, defined in section 4.2,
higher flow rates are needed given structural characteristics. Fire flow criteria are defined by
building size and material and determined using International Fire Code standards. For this study
fire flow criteria are as follows:
x System-wide (residential) > 1,000 gpm when below 3,600 sf & 1,500 when above 3,600
sf.
x System-wide (all other construction types) > 1,500 gpm
x Scenarios 1 and 2: Willits Commercial > 4,000 gpm, Basalt Industrial Park > 2,500 gpm
– 1,500 gpm (depending on building size).
x Scenario 3: ACE Lane/Kodiak Ski Lake Hotel > 4,000 gpm, Residential > 1,500 gpm
x Scenario 4: Crawfords (commercial) >3,000 gpm, Crawfords (residential) > 1,500 gpm
All non-residential buildings were considered Type IIA construction, which consists of fire
resistance building elements rated at one hour. The ACE Lane/Kodiak Ski Lake Hotel’s
materials are unknown at this time, but it’s assumed to contain a fire sprinkler system. Required
fire flows may be reduced depending on the approved size, building elements and if the structure
is equipped with a fire sprinkler system.
5. System Reliability: Ultimately, a water distribution system should be able to deliver water
despite expected and unexpected repairs that may be required. To achieve high system reliability,
the following strategies will be recommended as needed.
x Looping/Parallel Piping: This allows water to continue to travel throughout the system
even though a major transmission line is rendered inoperable.
x Distributed Production Source Locations: In places where only one pipe is responsible
for bringing water to a significant portion of the population, adding a source of potable
water in that area reduces the potential for water service to be interrupted if there is a
failure in that critical pipe.
5.1. Scenario 1
5.1.1. Scenario 1 – Existing Infrastructure Performance
System Operation Controls
For Scenario 1, the tank and well pump set points were modeled as they are currently
operated. They are shown in Appendix B.
Velocity
Under MDD and PHD conditions, model results indicate that the highest velocities occur
in the 4-inch outlet line of Well 3 and the header pipe connecting wells 1, 2 and 8. While
this does not negatively effect the operation of the system at this time, it may be prudent
to deal with these issues if well improvements are made in the future. All other velocities
and pressures in the system are below the 5.0 feet per second (ft/s) recommendation.
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 15
Pressure
The highest pressures occur in the outlet lines of wells 1, 2, and 8 and in the 2-inch
service line to the WWTF. These pressures are 152 and 136 psi, respectively. The
higher pressure areas previously mentioned do not appear to be a problem at this time as
there are no customer taps currently in these locations. However, future upgrades should
take these pressures into consideration. The results can be seen in Appendix C.
There are two locations in this scenario that have pressures below the ideal pressure of 50
psi. The lowest calculated pressure is in Zone 3 just south of the Aspen Junction tank.
The pressure in this area is 28 psi. In order to increase the pressure in this location a taller
water storage tank, larger booster pump and/or individual booster pumps could be
installed at the structures.
The other low pressure is located where the 12-inch distribution line from the BLM tank
crosses Original Rd. The pressure in this location is 45 psi. All other pressures for this
scenario are above 54 psi.
Water Storage
Tables 8 & 9 show that the existing system does not have adequate water storage, so
additional tank locations will be evaluated later in Section 5.1.2.
Table 9 Scenario 1 Simulated Water Storage Volume and Age
Tank
Min. Volume During
MDD (MG) Water Age (days)
BLM Tank 0.23 2.2
Blue Lake Tank 0.51 3.9
Aspen Junction 0.04 1.5
Total Simulated Vol. for Zones 1 & 2 0.74
Total Simulated Vol. for Zone 3 0.04
BLM & Blue Lake Min. Required Emergency & Fire Volume = 1.60 MG
Aspen Junction Min. Required Emergency & Fire Volume = 0.23 MG
Water Supply
During an MDD event, if the largest well, Well 8, is offline there is not sufficient water
production to meet demands. This prediction includes the addition of the Blue Lake II
tank or Ace Lane tank and optimizing the well controls to those in Appendix B. The
minimum storage volume for both tanks is 1.49 MG, which does not meet the
recommended 1.60 MG minimum storage volume.
As previously noted, Wells 3 and 4 are typically offline during the non-irrigation season,
normally September to May. If the largest well is also offline at this time, the model
predicts wells 1 and 2 can stabilize the tanks during ADD.
Available Fire Flow (w/o system upgrades)
The model-predicted available fire flows indicate that all locations were able to meet the
minimum fire flow requirements. It predicted all locations were able to obtain 1,000 gpm
and all but two nodes were able to meet 1,500 gpm or more. The locations of the lowest
available fire flow are at the highest elevations in the system. One location is the
northwest cul-de-sac of Cerise Ranch (1,405 gpm) and the other is located in Aspen
Junction (1,312 gpm) in the northern most cul-de-sac. While these locations were unable
to meet 1,500 gpm fire flows, they are only required to meet 1,000 gpm by code unless a
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN

______________________________________________________________________________________
SGM # 96059A-92 16
residence that would be served by the hydrant is over 3,600 sft. The results can be seen
in Appendix C.
If Cerise Ranch was required to meet a minimum of 1,500 gpm fire flow in the future,
one option would be adjusting the PRV located just below the Blue Lake Tank. It
appears by setting the PRV to approximately 90 psi, 1,500 gpm could be produced at all
locations in Cerise Ranch. However, by adjusting the PRV to a higher pressure or
hydraulic grade setting, it will increase the pressure at the lowest elevation in Cerise
Ranch to 123 psi, which is slightly above the 120 psi threshold. This increase in pressure
seems to be an acceptable tradeoff.
In addition, the minimum available fire flow to the Willits Commercial Area is 4,913
gpm, with a majority of the development above 5,000 gpm. This is above the 4,000 gpm
requirement. The Basalt Industrial Area’s available fire flow ranged between 1,595 and
5,600 gpm. The lowest available fire flow for the development is located at the end of
Park Avenue and Duroux Lane. These locations are also the portion of the Basalt
Industrial Area with the smallest fire flow requirement (1,500 gpm), which is based on
existing building size and construction type (IIA). The amount of flow is limited by the
6-inch water main feeding these locations. The 6-inch main should be replaced with a
larger size main if higher fire flows need to be met in the future.
System Reliability
Exhibit 4 shows the system’s weak points, as they relate to reliability, and are identified
at six locations.
Two are located where the water is conveyed from the system sources to the
storage tanks
Two are located along the transmission main from the storage tanks.
o One option to increase the reliability for both the supply lines and
transmission mains, as identified in this section, is to add a tie-in and
valve between the 8-inch supply line and the 12-inch transmission main.
The valve would normally be closed, but could be opened in the
event of an emergency.
A pipe maze could used to control disinfection and chlorine
contact time.
One is located within the southern portion of the District, which includes the
following existing developments: Basalt Industrial Park, Mid Valley Business
Center, River Oaks and Oak Groves.
o Two options exist for looping the infrastructure between the rest of the
District and these developments to ensure system reliability.
One option involves connecting an 8-inch line in Valley Circle
that is in the northeast portion of the Basalt Industrial Park and
the 8-inch line to the north in Lake Avenue. (option 1)
The other option involves connecting the 6-inch line at the end
of Park Avenue in the Basalt Industrial Park with the 8-inch line
to the north in Evans Rd, (option 2)
The other is located in the River Oaks development, which currently experiences
water hammer issues.
o Adding a connection between the 8-inch line in the cul-de-sac of River
Oaks and the 8-inch line in Willits Lane just south of Basalt Trade
Center would relieve the pressure surge in this area and improve pipe
longevity.

5.1.2. Scenario 1 – Proposed Infrastructure Performance
Additional Water Tank Location (Zones 1 & 2)
Two proposed 1-MG tank locations were selected for evaluation based on the District
boundary, access, topography, location, and property ownership. One site alternative is
located adjacent to the existing Blue Lake Tank and the other is located on the Ace
Lane/Kodiak Ski Lake Property. For the purpose of this study, we will refer to these
tanks as Blue Lake Tank II and Ace Lane Tank. The benefit of the Ace Lane property is
it is located between the two existing tanks, which would help increase system reliability.
Alternatively, a second Blue Lake Tank could utilize the existing 12-inch transmission
main, thereby reducing construction costs. However, this tank location does not improve
reliability since a break in that transmission line could take both Blue Lake tanks out of
service.
Both tanks were modeled at a base elevation of 6694 feet and as having the same height
and overflow height as the BLM tank. All supply lines were 8 inches and transmission
mains were 12 inches. The two proposed tanks will be reviewed with the optimized
controls as shown in Appendix B since this provides the greatest amount of storage for
the system.
Blue Lake Tank II Results
The model predicts this tank location meets the minimum recommended storage volumes
for the system and 7 day water age limit, see Table 10. It also predicts this tank location
has no effect on maximum system pressure, minimum system pressure and maximum
velocity. All fire flow requirements were met in the District for this scenario.

The transmission main from the Ace Lane tank was connected to the Willits commercial
area through an existing sleeve under HWY 82. This appeared to be the best connection
point as Willits is the largest fire demand at this time and it is centrally located within the

Upsizing Water Tank (Zone 3 & 4)
When the Aspen Junction tank was modeled as a 0.25 MG storage tank with the updated
controls shown in Appendix B, the model predicted the minimum storage volume was
met (Tables 10 & 11).
5.1.3. Recommendations for Proposed Infrastructure
x System Wide
o Monitor non-revenue water and investigate potential causes.
o Reduce the amount of non-revenue water to approximately 15%.
x Zones 1 & 2
o Bring additional 1.0 MG Blue Lake II tank online
9 Ex. Blue Lake tank infrastructure can reduce construction costs
9 Ace Lane property not expected to be developed until future scenarios
o Bring additional well online
9 Additional water supply (119 GPM) needed for firm production
deficit
9 Well should be tied into the Blue Lake supply line as this is the
location of the largest well and due to the possibility of Robinson
ditch being piped
x Zone 3 & 4
o Increase the size of the existing Aspen Junction tank to 0.25 MG or add an
additional 0.20 MG tank with same base elevation, overflows, etc.
o Require residences in the northern portion of Aspen Junction to install
individual booster pumps. An alternative is to increase the height of the
water storage tank or increase the size of the booster pump.
5.1.4. System Performance When Ex. Wells 3 & 4 Offline
For this analysis it was assumed that the recommendations for the proposed infrastructure
have been completed, except for the non-revenue water, as taking Wells 3 & 4 offline
increases the current storage capacity and firm production shortage. The model will not
include the additional well brought online to increase the firm capacity as this well is for
emergencies only.
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 19
The model predicts the addition of a 1.0 MG Blue Lake II tank with existing Wells 1, 2
and 8 are able to maintain a minimum storage volume of 1.60 MG, which meets the
recommended storage capacity. However with Wells 3 & 4 offline, the firm production
capacity deficit is increased to 489 gpm (Table 5). Since it was assumed the additional
well (120 gpm) was brought online to meet firm production, there is only a need for an
additional 370 gpm. This production capacity could require the use of more than one
additional well to meet the deficit. The additional wells should be connected to the Blue
Lake supply line.
5.2. Scenario 2
See Exhibit 4 for Scenario 2 proposed well and tank locations.
5.2.1 Scenario 2 – Proposed Infrastructure Performance
Infrastructure Assumptions
x The tank and well pump controls were modeled at the same optimized settings as
in Scenario 1 with the exception of the proposed wells. The settings are shown in
Appendix D.
x The capacity of the Aspen Junction tank was increased to 0.25 MG during
Scenario 1 improvements.
x All proposed transmission mains connected to the tanks are 12 inch and all
supply lines to the tanks from the wells are modeled as 8 inch.
x All proposed development piping for this scenario was modeled as 8-inch with
the exception of Arlian Ranch, which included an extension of the 12-inch
transmission main west along Highway 82.
x The two proposed tanks in this section use the same sites and names as in
Scenario 1.
x The additional well (120 gpm) to increase firm production as recommended in
Scenario 1 is assumed to be online, but was not modeled as part of the water
supply as this well is for emergency use (i.e. when other wells are offline).
Pipe Velocities
Under MDD conditions, the model results predict the maximum velocities occur in the
same locations and have the same magnitudes as in Scenario 1. All velocities are below
the recommended thresholds.
Under PHD conditions, the velocities remain the same for the wells and supply lines to
the water storage tanks. However, the velocities in the system increase under peak hour
demand conditions. All velocities in the system are below 4.2 ft/s.
System Pressures
The maximum and minimum system pressures, as predicted by the model, occur in the
same locations and have the same magnitudes as in Scenario 1. The results can be seen
in Appendix E.
Water Storage
As in Scenario 1, Table 8 shows that the existing system does not have adequate water
storage. Additional tank locations will be evaluated later in this section. The minimum
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 20
recommended water storage volume for this scenario is 2.0 MG. For the purpose of this
study we will assume no additional water storage upgrades have been made and only the
three existing tanks are online.
Water Supply
The District currently has 7 decreed locations at which production wells could be sited.
The closest wells to the existing system will be reviewed in this scenario, which include
wells 9 and 10. All wells were modeled at a 300 gpm output rate as this was the
difference between the MDD and existing production capacity.
Proposed Water Storage & Water Supply Results
1. Blue Lake Tank II Results
Table 12 shows the minimum storage volume and water age recommendations are met
with the addition of a 1.5 MG tank and Well 10. As in Scenario 1, the model predicts this
tank location has no effect on maximum system pressure, minimum system pressure and
maximum velocity.
If Well 10 cannot be permitted then the size of the tank would need to be increased to 2.0
MG and Well 9 would need to be brought online in order to meet the minimum
recommended storage volumes. Increasing the capacity of the Blue Lake II tank helps
stabilize the existing BLM tank and keep it from crashing. The addition of Well 9
increases the pressure in the Blue Lake supply lines and wells to 150 and 160 psi,
respectively, and increases velocities in the well header and supply line to 7.2 ft/s. While
these pressures and velocities occur during ADD and MDD and are slightly higher then
the recommended thresholds they do not pose a risk to pipe integrity at this time.

Again, if Well 10 cannot be permitted then the size of the tank would need to be
increased to 3.75 MG and Well 9 would need to be brought online in order to meet the

Available Fire Flow
The model-predicted available fire flows indicate that all locations were able to meet the
minimum fire flow requirements with either tank location. The results can be seen in
Appendix E.
System Reliability
It is assumed that the system improvements, as they relate to the weak points outlined in
Scenario 1, where previously completed.
An additional weak point could exist if the Ace Lane tank was constructed without the
addition of a well to serve it. The addition of a well in this location would greatly
improve system reliability because it would not have to rely on wells associated with the
other storage tanks in the District. It would have a direct connection to a water source
that could continue to deliver water when other wells, supply lines and/or transmission
mains are out of service.
As in the first scenario, the Blue Lake II tank should include a supply line and
distribution line connected to the existing Blue Lake tank lines.
5.2.2. Recommendations for Proposed Infrastructure
x Zones 1 & 2
o Bring additional 2.0 MG Blue Lake II tank online
9 Given the possibility of the Robinson Ditch being piped additional wells
in the southeast portion of the District connected to the BLM tank
supply line may not be possible.
9 Ex. Blue Lake tank infrastructure can reduce construction costs
9 Ace Lane property not expected to be developed until future scenarios
o Bring existing decreed well associated with Blue Lake tank online
9 Additional well needed to meet expected MDD
9 Well should be connected to Blue Lake supply line
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 22
9 This location is recommended due to the possibility of the Robinson
Ditch being piped.
o Upsize Blue Lake well header and supply line to the tank
9 A 12-inch line upgrade would reduce the pressures and velocities below
the recommended thresholds.
o Bring additional well online
9 Additional water supply (260 GPM) needed for firm production deficit
9 Again, the well should be connected to Blue Lake supply line.
5.2.3. System Performance When Ex. Wells 3 & 4 Offline
As in Scenario 1, it was assumed that the recommendations for the proposed
infrastructure have been completed. The additional well brought online to increase the
firm capacity will not be modeled as this well is for emergencies only.
The model predicted an increase in capacity of the Blue Lake II tank from 2.0 to 3.0 MG,
two additional 400 gpm wells connected to the Blue Lake supply line and a 12-inch
parallel transmission line from Arlian Ranch to the Basalt Industrial Park with a 12-inch
tie-in to the Willits Commercial area were unable to keep the existing BLM tank from
crashing after 44 hours.
Results also showed there were pressures around 200 psi in multiple wells and velocities
in the supply line in excess of 10 psi under MDD conditions. Given these results it is
evident water production directly connected to the existing BLM tank is required to meet
future demands with the District.
5.3. Scenario 3
See Exhibit 4 for Scenario 3 proposed well, tank and PRV locations.
5.3.1. Scenario 3 – Proposed Infrastructure Performance
Infrastructure Assumptions
x The tank and well pump controls were modeled at the same optimized settings as
in Scenario 2 with the exception of the proposed wells. The settings are shown in
Appendix F.
x It is assumed two wells are online and connected to the BLM tank with the same
outputs as Wells 3 & 4.
x The 2.0 MG Blue Lake II tank is online in addition to a 300 gpm well in the
northwest portion of the District connected to the Blue Lake supply.
x All proposed transmission mains connected to the tanks are 12 inch and all
supply lines to the tanks from the wells are modeled as 8 inch.
x All proposed development piping for this scenario was modeled as 8-inch with
the exception of Arlian Ranch, which included an extension of the 12-inch
transmission main west along Highway 82.
x The Ace Lane tank in this section uses the same sites and names as in past
scenarios.
x The additional well (260 gpm) to increase firm production as recommended in
Scenario 2 is assumed to be online, but was not modeled as part of the water
supply as this well is for emergency use (i.e. when other wells are offline).

Additional Review
Besides velocities, pressures, and fire flow; this scenario reviewed the need to extend the
12-inch transmission main from its termination point just east of Arlian Ranch to the TCI
Lane Property west of the current District boundaries. This extension included a
connection with the 8-inch water main that currently terminates at the southern end of
Cerise Ranch Road in Cerise Ranch. This 12-inch transmission main extension will also
require a PRV near Arlian Ranch to help maintain the current operating pressures within
Zone 2. The PRV was set to the same operating pressure as the existing PRV in Blue
Lake. This portion of the model helped determine the effects the extension had on the
water distribution system, which includes pressure, velocities, fire flows, and reliability.
Due to elevation differences between the existing zones and proposed development
locations, the need for an additional pressure zone, which we will call Zone 5, controlled
by PRV’s will be reviewed. The PRV’s were set to an operating pressure that kept the
lowest elevation within the Zone near 115 psi. This Zone encompasses all the new
development to the west of the District boundaries and south of Highway 82. See
Exhibit 2 for further information.
Pipe Velocities
Under MDD conditions, the model results show the max velocities occur in the same
locations as in Scenario 1, although the magnitudes in the well outlet lines and supply
lines to the tanks have increased. As noted in Scenario 2, this is due to an additional well
being brought online at the Blue Lake location. If well and/or supply line upgrades are
performed in the future, the District should look at increasing the size of these lines or
creating a direct tie-in to the system with a pipe maze in order to obtain the required
chlorine disinfection and contact time. All other velocities are below the recommended
thresholds.
Under PHD conditions, the velocities remain the same as during MDD for the wells and
supply lines to the water storage tanks. However, the velocities in the distribution
network increase under peak hour demand conditions. All velocities are below the 10 ft/s
threshold.
Results indicate the extension of the 12-inch transmission main from Arlian Ranch to the
TCI Lane development does not cause a significant increase or decrease in pipe
velocities.
System Pressures
The maximum and minimum system pressures, as predicted by the model, occur in the
same locations and have the same magnitudes as in Scenarios 1 and 2, although the
magnitudes in the well outlet lines and supply lines to the tanks have increased. The
same recommendations as were discussed under Pipe Velocities are suggested to lower
hese pressures. The results can be seen in Appendix G.
The model predicted the 12-inch transmission line extension from Arlian Ranch to TCI
Lane Properties had minimal effect on maximum pressure and minimum pressure in the
distribution system.
Water Storage
As in Scenarios 1 and 2, Table 8 shows the existing system does not have adequate water
storage. Additional tank locations will be evaluated later in this section. The minimum
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 24
recommended water storage volume for this scenario is 2.4 MG. Since the Blue Lake II
tank was oversized the recommended additional storage capacity is 0.5 MG.
Water Supply
The District currently has 6 possible well locations that could supply the additional
required water. The closest wells to the existing system will be reviewed in this scenario,
which include wells 7 and 10. All wells were modeled at a 400 GPM output rate because
this additional output combined with the existing wells matches the MDD for this
scenario.
Proposed Water Storage & Water Supply Results
The tanks were modeled as 0.50 MG storage tanks based on the required storage volume
shown in Table 8 and a 2.0 MG Blue Lake II tank.
Kennel Tank Results
After initial review, model results indicate this tank location has minimal effect on the
system because it is located in a PRV controlled zone where demand is relatively low.
Since it is in a PRV controlled zone it cannot supply water or aid with fire flows to the
rest of the District. Furthermore, all fire flow requirements were not met with the
constraints not being met in Willits Commercial and part of Ace Lane/Kodiak Ski Lake
property.
Ace Lane Tank Results
When the additional water source for this scenario is connected to the Blue Lake supply
line it results in velocities above 10 ft/s and pressures around 200 psi in the supply line.
It also does not stabilize the Ace Lane tank during MDD. The model predicted a 3.0 MG
Ace Lane tank would be required to meet the minimum recommended storage volumes
when this water source location is utilized.
The minimum size of the Ace Lane tank when the additional water source is added to the
BLM tank supply line is 0.50 MG. Table 14 shows that the minimum storage volume is
met during MDD, but the water age is slightly higher then the 7 day threshold during
ADD. The water age in the Blue Lake tanks could be lowered by further adjusting the
tank controls.
The model predicted this tank location has minimal effect on the maximum and minimum
system pressure. The 12-inch transmission line extension from Arlian Ranch to TCI
Lane in combination with this tank also had minimal effect on system pressures and
velocities during ADD and MDD events. All fire flow requirements were met in the
District for this Scenario.

Available Fire Flow
When the proposed 0.50 MG Ace Lane tank without the 12-inch transmission main
extension is modeled all fire flow requirements are not met. However, when the
extension is included in the model it predicts all requirements are met. The results
indicate that all locations are able to obtain 1,000 gpm and all but one node was able to
meet 1,500 gpm or more. As in Scenario 2, the location of the lowest available fire flow
was in Aspen Junction. The results can be seen in Appendix G.
System Reliability
It is assumed that the system improvements, as they relate to the weak points outlined in
Scenario 1, where previously completed. It is also assumed that the Blue Lake II tank
was constructed with both supply and transmission main lines as discussed in Scenario 2.
An additional location is the Ace Lane tank, since it does not have a direct water supply
it must rely on the other tanks and their supply wells in order to fill the tank.
By connecting the supply lines to the 12 inch transmission main from each well, as
recommended in past scenarios, the Ace Lane tank could be indirectly fed by these wells
without the water first having to travel through the Blue Lake tanks or BLM tank. This
connection would also allow the wells to supply the system if a tank, transmission line or
supply line had to be taken offline.
It should be noted that all developments except Aspen/Basalt Trailer Park, KOA, Glassier
Property, Vaugner Property and Fitzsimmons were modeled as looped systems. Meaning
the development had two connection points into the existing system for reliability.
5.4.2. Recommendations for Proposed Infrastructure
x Zones 1 & 2
o Bring additional 0.5 MG Ace Lane tank online
9 Ace Lane property expected to be developed in this scenario.
9 This location is central to the District and will help provide redundancy.
o Bring existing decreed well online associated with BLM tank
9 Additional well needed to meet expected MDD.
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 26
9 Well should be connected to BLM supply line.
9 A well is needed in this location to keep the BLM and Ace Lane tank
stabilized during MDD.
9 The addition of a well in this location allows for the most economical
tank size.
o Bring additional well online
9 Additional water supply (150 GPM) needed for firm production deficit
9 This well should be connected to BLM supply line as all past firm
production wells were recommended for the Blue Lake supply line.
5.4. Scenario 4
See Exhibit 4 for Scenario 4 proposed well, tank and PRV locations.
5.4.1. Scenario 3 – Proposed Infrastructure Performance
Infrastructure Assumptions
x The tank and well pump controls were modeled at the same optimized settings as
in Scenario 3 with the exception of the proposed wells. The settings are shown in
Appendix H.
x All of the Scenario 3 infrastructure assumptions are also assumed for this
scenario.
x The 12-inch transmission main extension from Arlian Ranch to TCI and the
associated PRV’s were constructed due to fire flow requirements.
x An additional well or water supply with a 400 gpm ouput rate has been brought
online and is connected to the BLM tank supply line.
x The 0.5 MG Ace Lane tank is online and is connected to the system with a 12-
inch transmission main.
x The additional well (150 gpm) to increase firm production as recommended in
Scenario 3 is assumed to be online, but was not modeled as part of the water
supply as this well is for emergency use (i.e. when other wells are offline).
x Crawfords is a looped system that connects the existing 8-inch stub at
Wendys/Texaco on El Jebel Rd. to the Blue Lake development on JW Dr. This
connection will require a PRV by the Blue Lake development operating at Zone
2 pressures.
x Since the Ace Lane tank is the preferred location for Scenario 3 we will assume
the tank capacity is increased to 1.0 MG to in order to meet the recommended
storage capacity.
Pipe Velocities
Under MDD conditions, the model results show the max velocities occur in the same
locations and have the same magnitudes in the well outlet lines and supply lines to the
tanks as in Scenario 3. However, there is a location with velocities that exceed 5 ft/s. It
is located in the 8-inch main (on El Jebel Road) currently connecting Wendys/Texaco
with the rest of the District. This is also part of the proposed loop for the Crawford’s
development from the south. The velocity through this main up to Gillespie Drive is 5.1
ft/s. All other velocities in the distribution system for this scenario are below the
recommended thresholds.
Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 27
The model was rerun with the 8-inch main upsized to a 10-inch from the Wendys/Texaco
stub up to Gillespie Drive. The model predicted the velocity was 3.3 ft/s.
Under PHD conditions, the velocities remain the same for the wells and supply lines to
the water storage tanks. All velocities are below the recommended threshold.
System Pressures
The maximum and minimum system pressures, as predicted by the model, occur in the
same locations and have the same magnitudes as in Scenarios 3. However, the Basalt
Bluffs development has a minimum pressure of 46 psi. The results are shown in
Appendix I.
Water Storage
As in the other scenarios, Table 8 shows the existing system does not have adequate
water storage. The minimum recommended water storage volume for this scenario is 2.5
MG.
Water Supply
The District currently has 5 possible well locations that could supply the additional
required water. The closest wells to the existing system will be reviewed in this scenario,
which include wells 7 and 12. All wells were modeled at a 300 GPM output rate because
this water supply in addition to the existing non-firm wells equals the MDD for this
scenario.
Proposed Water Storage & Water Supply Results
The Ace Lane tank was upsized and modeled as 1.0 MG storage tanks based on the
required storage volume shown in Table 8.
Upsizing Ace Lane Tank Results
When the model is evaluated with the proposed 1.0 MG tank and the additional well
connected to the BLM tank supply line, the model predicts minimum storage volumes are
not met. However, when the tank capacity is increased to 1.5 MG the model predicts the
minimum storage volume is met a shown in Table 15.
When the additional water source for this scenario is connected to the Blue Lake supply
line it results in velocities above 10 ft/s and pressures around 200 psi in the wells and
supply line to the Blue Lake tank. In addition, the water supply does not keep the
existing BLM and the proposed 1.5 MG Ace Lane tank from crashing.

able to meet fire flow requirements. The results indicate that all locations are able to
obtain 1,000 gpm and all but one node was able to meet 1,500 gpm. As in Scenario 3, it
is located in Aspen Junction. The results are shown in Appendix I.
System Reliability
The looped connection between Crawfords and Blue Lake will also help with system
reliability as water could be supplied to the other zones in times of high usage or
infrastructure repairs. This connection would need a PRV as two different pressure zones
would be connected with this loop.
System Reliability
It is assumed the system weak points as identified in past scenarios have been completed.
No other items exist for this scenario

Mid Valley Metropolitan District WATER SYSTEM MASTER PLAN
August 2008
______________________________________________________________________________________
SGM # 96059A-92 30
¾Additional 300 gpm well needed to meet expected MDD
9 These well locations are recommended because water supply is
required to stabilize the BLM and Ace Lane tanks during MDD.
9 Adding additional water supply to the BLM tank allows for the most
economical tank size and reduced infrastructure improvements.
o Extend 12-inch transmission main from Arlian Ranch to TCI Lane and
provide the necessary PRV’s
9 This is required to meet fire flow requirements
o Crawfords should anticipate at least a 10-inch main looped from
Wendys/Texaco to Blue Lake. This will require a PRV before the Blue
Lake connection.

1 SUMMARY
This Wildlife and Vegetation Assessment Report details the habitats, wildlife use patterns,
noxious weed conditions and provides recommended mitigation measures for the proposed
development of the TCI Lane property along the Roaring Fork River in Garfield County,
Colorado (see Figure 1). The land owner is proposing to subdivide the property into 89
units on 89 lots within the 100-acre parcel. This report is for the Preliminary Plan for a PUD
process with Garfield County.
Mr. John Groves, District Wildlife Manager with CDOW, was consulted regarding the
development of this property. Mr. Groves has requested, and was provided a copy of this
report.
The site is located approximately 3 miles east of Carbondale, near the Catherine site,
adjacent to the Roaring Fork River. The property is currently used as a winter pasture for
cows, with spring calving operations. Cows and calves are pulled off of the property in late
April, and return to the property in late October. The property extends from Old Highway
82 down to the Roaring Fork River. Upland areas at the northern end of the property are
dominated by agricultural grasses and forbs, including timothy (Phleum pratense), alfalfa
(Medigaco sativa), redtop (Agrostis stolonifera), meadow fescue (Festuca pratensis), and clover
(Trifolium pratense). Remnant native species include Gambel’s oak (Quercus gambelii) and
sagebrush (Artemisia tridentata ssp. pauciflora) and weeds such as plumeless thistle (Carduus
acanthoides), absinth wormwood (Artemisia absinthium) and Canada thistle (Cirsium arvense)
were common, but are currently being treated.
As the site has been used as a working ranch for close to 100 years, the pastures have been
significantly altered from this ranching use. Blue Creek is a very old ditch system which
flows from east to west through the property. Blue Creek has various lateral ditches coming
off of the main Creek, and irrigates a wide swath through the property. The wetlands
created by Blue Creek are extremely rich in plant species composition and diversity. During
a wetland delineation conducted in 2007, the Federally listed plant Ute Ladies’-tresses
orchid (Spiranthes diluvialis) was discovered in these wetlands. Over 1,000 of these plants
were located, constituting a significant range expansion for the species. The US Fish and
Wildlife Service (USFWS) has been consulted regarding this discovery, and TCI Lane has
significantly altered their development plans to avoid impacts to the orchid, and has
proposed adopting a management plan with coordination through the Roaring Fork
Conservancy to help manage the site for the long-term protection of this species.
The property supports use by wild turkey, mule deer, some light elk use, as well as use by
other species including Lewis’ woodpecker, raccoon, skunk, fox, coyote, and Brown trout in
Blue Creek, as well as many other wildlife species. The southern border of the property is
the Roaring Fork River, which is an important wildlife area and supports a very healthy
fishery.

2 EVALUATED SPECIES
Information on species status, distribution, and ecology was derived from USFWS recovery
plans, Colorado Natural Heritage Program maps and reports, Colorado Division of Wildlife
(CDOW) habitat mapping, various scientific studies and reports, and field reviews. The
USFWS list of Threatened and Endangered Species was used to determine if any species
potentially occurred within or adjacent to the property. Additionally, the CDOW’s list of
Threatened, Endangered, and Species of Concern was referenced to determine if potential
habitat for any of these species occurred on or adjacent to the property.
Species chosen for impacts analysis have high biological, political, and public interest, as
well as regulatory guidance. Individual wildlife species and groups not specifically
mentioned in this assessment are not “insignificant;” they are simply not presently at issue
because the limited extent of the proposed development would avoid or minimally impact
these species and their habitats.
Research was conducted by Rocky Mountain Ecological Services and WP Natural Resource
Consulting (Park City, Utah) to determine relevant habitat associations, life-history traits,
the rangewide or statewide distribution of known populations, and current status and trend
of each species.
The Colorado Natural Heritage database was consulted to ascertain the existence of known
occurrences within the project area. Habitat surveys were conducted during many site
visits in 2007 and 2008 by Eric Petterson, Principal Ecologist of Rocky Mountain Ecological
Services, Inc., and Mindy Wheeler, Plant Ecologist with WP Natural Resource Consulting.
For the following species of concern, habitat was either located on, or adjacent to, the
property:
o Mule Deer
o Elk
o Black Bear
o Wild Turkey
o Lewis’s woodpecker
o Ute Ladies’-Tresses Orchid
Ute Ladies’ Tresses Orchid is a Federally Threatened species, and as such is regulated by the
Endangered Species Act (1973 as amended) through the USFWS.

4 EXISTING CONDITIONS
4.1 HISTORICAL USE AND IMPACTS
The northern portion of the property is
dominated by agricultural cultivars such as
smooth brome (Bromus inermis), orchard grass
(Dactylis glomerata), timothy, and redtop. The
site historically (pre-settlement) supported
sagebrush (Artemisia tridentata var. pauciflora),
with intermittent stands of Gambel’s oak.
Now, with long-term irrigation of the
uplands, most of the sagebrush that was likely
once cleared would have a difficult time
reestablishing. However, stands of Gambel’s
oak are persistent on the property. Because of
the yearly irrigation of the meadows, coyote
willow (Salix exigua), Baltic rush (Juncus
balticus) and other more wetland obligates have become established in the upland areas,
amid the Gambel’s oak. The meadows were relatively weedy, but TCI began to treat these
weeds in 2007, and is continuing to treat them in 2008. The long-term presence of the
irrigation ditches has allowed the establishment of narrowleaf cottonwood along certain
areas. These cottonwood stands are very mature, and support a dense, shrubby understory.
The southern end of the property is dominated by narrowleaf cottonwood riparian
woodlands, interspersed with irrigated meadows, widespread wetland complexes, and
some drier meadows. This area is also used for calving operations, and some winter range
grazing for cattle. The southern end of the property is bordered by the Roaring Fork River
(HUC 14010004), which is a large, perennial river that discharges an average of 1,380 cubic
feet per second (cfs) (USGS 2008). At the time of this writing, the river was flowing at 4,560
cfs.
The historical cattle grazing has left many of the meadows fairly compacted, with reduced
plant diversity. As the grazing generally occurs during the fall, winter, and spring months,
the summertime growing season is not significantly impacted, and this allows for wetlands
to flourish with minimal negative impacts.
At the center of the property, the old ranch house and associated outbuildings are located.
Various trees surround these buildings, including various fruit trees. The homes are still
occupied, and the outbuildings are commonly used.

5 CURRENT VEGETATION CONDITIONS
The following list outlines the vegetation communities present at the property followed by
short descriptions:
Oakbrush Shrubland – Oakbrush
(Quercus gambelii), also known as
Gambel’s oak, is a dominant shrub in
the drier uplands on the north side of
the property, mostly adjacent to the
frontage road and within some of the
irrigated pastures. The understory of
the oakbrush has been altered by years
of grazing and loafing of livestock in
these areas. Thus, the understory
species in this area are indicative of
disturbance, and is dominated by
species such as garden orach (Atriplex
heterosperma), smooth brome, and
Indian hemp (Apocynum cannabinum).
These areas occupy about 2.8 acres on the ranch.
Upland Meadow – The upland meadows of the property have had different uses over the
years and thus differ significantly in vegetation composition. The upland meadow on the
east side of the property is almost devoid of vegetation due to this area being used for a
livestock pen for cow/calf pairs for many years.
The upland meadows in the south-central portion of the property are dry areas that lie
above the water table and do not
benefit from irrigation ditches. Plant
species in these areas are indicative of
these drier conditions and include
orchard grass (Dactylis glomerata),
Kentucky bluegrass (Poa pratensis), as
well as noxious weeds that prefer drier
habitats such as Scotch thistle
(Onopordum acanthium) and absinth
wormwood. Approximately 9.5 acres
on the property are upland meadows.
TCI Lane Wildlife and Vegetation Assessment Report July 2008
ROCKY MOUNTAIN ECOLOGICAL SERVICES, INC. 6
Irrigated Pasture – Approximately 37.7 acres of the property consist of irrigated pastures.
Vegetation communities also differ significantly on these irrigated pastures since the ditches
on the north side of the property were not allowed to flow this year. Dominant species in
the dry parts of the north pastures include alfalfa (Medicago sativa), curly cup gumweed
(Grindelia squarrosa), wooly plantain (Plantago patagonica), and bindweed (Convolvulus
arvensis). In more mesic areas within the irrigated pastures, additional species include
orchard grass, Kentucky bluegrass, and alsike clover (Trifolium hybridum), as well as a fair
amount of Canada thistle (Breea arvense).
Cottonwood Riparian Forest – About 34.1 acres of
the property are cottonwood riparian forest,
which is the dominant vegetation type on the
south side of the property. The upper canopy of
these areas are dominated by narrow leaf
cottonwood (Populus angustifolia), with
hawthorne (Crataegus rivularis), buffaloberry
(Sheperdia rotundifolia) and skunkbush (Rhus
trilobata) as dominants in the shrub layer.
Understory species include clematis (Clematis
ligusticifolia), orchard grass, and Kentucky
bluegrass. The noxious weed houndstongue
(Cynoglossum officinale) is common and relatively
abundant throughout the understory of the
cottonwood forest, along wtih common burdock
(Arctium minus), and Canada thistle. Russian
olive (Elaeagnus angustifolia) is also found
intermittently within these woodlands.
Irrigated pastures on north end of property. Irrigated pastures on the south end.
TCI Lane Wildlife and Vegetation Assessment Report July 2008
ROCKY MOUNTAIN ECOLOGICAL SERVICES, INC. 7
Ditch – Irrigation ditches occupy about 0.4 acres on the property. These ditches carry water
throughout the property to irrigate the pastures for livestock. Several of these ditches will
likely be obliterated or moved with the development of the property.
Wet Meadow – Wet meadows
account for about 2.4 acres of the
property. These areas are located in
the low-lying depressional areas as
well as areas that are fed by irrigation
ditches. Species in wet meadows of
the property include Nebraska sedge
(Carex nebrascensis), wooly sedge
(Carex lanuginosa), orchard grass,
showy milkweed (Asclepias speciosa)
and Kentucky bluegrass.
Wetland- Herbaceous- Herbaceous wetlands
account for about 5.3 acres of the property.
These areas are kept wet throughout the
growing season either by Blue Creek or
historic irrigation ditches. Dominant plant
species include Nebraska sedge, beaked sedge
(Carex utriculata), creeping spikerush
(Eleocharis palustris), orange jewelweed
(Impatiens capensis) and swordleaf rush
(Juncus ensifolius). These wetlands also
support the USFWS designated Threatened
plant Ute Ladies’ Tresses Orchid (Spiranthes
diluvialis).
TCI Lane Wildlife and Vegetation Assessment Report July 2008
ROCKY MOUNTAIN ECOLOGICAL SERVICES, INC. 8
Wetland – Forested – Forested wetlands
occupy about 1 acre in the southeast
corner of the property and are fed by a
lateral irrigation ditch from Blue Creek.
The dominant overstory tree is narrowleaf
cottonwood, with species such as
hawthorn and alder (Alnus tenuifolia) in
the shrub layer. Dominant herbaceous
species include woolly sedge, bittersweet
nightshade (Solanum dulcamara), Indian
hemp and reed canary grass (Phalaris
arundinaceae).
Willow Shrubland – These shrublands
occupy about 1.9 acres of the property and
are interspersed throughout the property.
Many of the willow shrublands in the
interior of the property are dominated by
coyote willow (Salix exigua) and are
regularly browsed by cattle. Thus these
shrublands are somewhat sparse in nature
and have a limited understory of orchard
grass and Kentucky bluegrass. The willow
shrublands on the edges of the property
are very dense and can include Rocky
Mountain willow (Salix monticola) within
the stands. Reed canary grass is a
common grass in these areas.
Disturbance – The areas typed
‘disturbance’ includes roads and houses
and occupies about 2.5 acres.

6 PROPOSED DEVELOPMENT
TCI Lane Ranch and their representatives at Noble Design Studio are proposing the
designation of 89 residential units, with associated roads and infrastructure (Figure 3).
Waste water will be treated via a fully mechanical community wastewater treatment system
located in self-contained buildings in the center of the project, with an outflow of treated
water delivered to the Roaring Fork River. Outflow to the Roaring Fork would be
approximately 0.098 million gallons per day. However, there could be a possible connection
with Roaring Fork Water and Sanitation District (which would negate the need for a
community wastewater treatment system). Water supplied for residential consumption will
come from a series of new wells and a community water system; existing wells will be
abandoned and water rights will be transferred to the new wells.
The 89 homes are to be constructed off-site, and brought in as sections. This will reduce
construction traffic, keep construction costs down, and ensure higher energy efficiency
standards for the homes (J. Fredericks, Noble Design Studio, pers. comm. 2007-2008).
Approximately 20 to 30 units will be constructed (and sold) per year. Additional amenities
include a Community Garden, a possible foot bridge over the Roaring Fork River to link
with the Rio Grande Trail, a dog park, and playgrounds. Many of the irrigation ditches will
be abandoned; however, some will remain in use to supply irrigation waters for cottonwood
trees, and to provide continued hydrology for the Ute Ladies’-tresses orchid areas.

7 WILDLIFE USE OF AREA & IMPACTS OF DEVELOPMENT
7.1 MULE DEER
The property has relatively low, but year-round levels of mule deer use. The property likely
supports a small herd of approximately 5 to 10 deer, which may swell slightly during the
winter months. CDOW’s Natural Diversity Information System (NDIS) has mapped the
area as a Resident Population area, Summer Range, and the area adjacent to the Highway 82
corridor as a Highway Crossing area (see Figure 4 and Figure 5, and see Appendix I for
definitions). NDIS mapping depicts rough area boundaries of habitat use patterns;
however, on-site verification is recommended and CDOW reserves the right to change
NDIS habitat boundaries. Given the development of the Waldorf School, deer crossing of
Highway 82 has likely shifted to the west. Deer tend to stay in the riparian cottonwood
forests near the Roaring Fork River, but they commonly venture into pasture areas during
the nighttime hours. During the summer months, the abundance of water on the property
would continue to draw deer in.
Despite the thoughtful layout of the development, development of the property will
inevitably make a portion of suitable habitats unavailable for deer use. By clustering homes
in open areas and keeping large tracts of habitats open and undeveloped, mule deer use of
the area will definitely continue. Deer can become habituated to human activities,
especially if strict dog policies are enforced and habitat refugia are incorporated into the
plan. Given the low density, clustering of the lots, and significant areas of open space being
preserved through Conservation Easements, mule deer habitats would be preserved.
Unavoidable impacts would be from direct loss of habitat from homesites and roads.
Indirect habitat loss would likely occur near roads and homes from the impacts of human
use and human activities. Deer would likely have reduced foraging opportunities around
homesites, and reports have shown that stress levels for deer using suburban environments
are manifested in lowered reproductive success and decreased populations.
Deer utilize the dense, shrubby cottonwood forests and riparian areas as security cover, and
retention of these areas and avoidance of these areas by roads, homesites, and other uses
would increase the ability for deer to use the area after development. Dogs can have a
significant impact on the ability of deer to use shrubby habitats that are adjacent to
residential lots.
Unrestricted dogs in the subdivision will likely exclude any significant deer use of these
open spaces, and placement of a dog park within the subdivision, away from higher-quality
habitats along the cottonwood forests, will help enable continued deer use. The writer’s
professional opinion is that dog parks, located away from higher quality habitats, can help
deter dog use of quality habitats, and would provide dogs and their owners good areas to
recreate away from deer habitats. Even with dogs in kenneled or fenced yards, their
barking and activities may keep deer away from homesite areas. Also, it is inevitable that
off-leash or loose dogs will chase deer within the subdivision. This would be especially
critical during fawning periods (June), as dogs could easily overtake and kill fawns.
TCI Lane Wildlife and Vegetation Assessment Report July 2008
ROCKY MOUNTAIN ECOLOGICAL SERVICES, INC. 13
Summary – Development of the TCI Lane Ranch is designed to leave large blocks of habitat
relatively intact for continued deer use. However, the indirect effects of dogs and increased
human activity would compound unavoidable habitat losses. Deer use of habitats around
homesites will likely continue, although at a lower level, and with changed timing of use.
Deer would generally find cover in the thickest patches of shrubs, and venture forth into
meadows during the evening and nighttime hours. Therefore social and planned trails
through the cottonwood areas should be avoided or minimized.
Mule deer use would be modified and more limited, but use of habitats would still likely
occur. As deer will have more human activity around them, there will be increased stress
levels. Deer damage to landscaping is almost guaranteed. The large blocks of open space
on the property will allow for some refugia for deer, and will definitely help with continued
utilization of more fragmented and modified areas of the property. Given the small size of
the project, and available habitat in the areas to the south of the property, this project would
have insignificant impacts to mule deer populations.
