RE: Spring Valley Ranch PUD Legal Water Supply
Dear Glenn,
This letter is on behalf of Spring Valley Holdings, LLC regarding the legal water supply
available to Phase 2 of the Spring Valley Ranch PUD. In addition, this letter provides responses
to address conditions of approval stated in prior Garfield County approvals for the PUD.
In sum, Spring Valley Holdings owns water rights and augmentation plans that provide a
legally adequate water supply for the entire PUD, including Phase 2. The Phase 2 water supply
will be provided by two existing permitted wells located on the Spring Valley Ranch property, and
by surface water diverted pursuant to Spring Valley Holdings’ senior irrigation water rights.
Analysis of the physical supply available to Phase 2 is provided by Roaring Fork Engineering in a
separate memo.
I.Phase 2 Legal Water Supply
A. Summary.
Spring Valley Holdings owns water court decrees for changes of water rights and plans for
augmentationauthorizinguse of water sufficient for the entire Spring Valley Ranch PUD including
residential and commercial uses and irrigation of golf course, open space landscaping, and
agricultural open space, as shown on the project plans. A list of the decrees, well permits, and
structures available to provide water service to the PUD is included as Exhibit A and available via
this link, [https://bit.ly/3uXo2BS]. Spring Valley Holdings also holds Basalt Water Conservancy
District water allotment contracts by which the Basalt District provides augmentation water to
offset out-of-priority depletions from the development. Copies of these contracts and the
assignments of the contracts to Spring Valley Holdings are attached as Exhibit B and available
via this link, [https://bit.ly/357H11B].

B. Senior Irrigation Rights.
Spring Valley Holdings owns all of the senior ditch water rights from Landis Creek,
totaling 12 cfs with priority dates in the 1880’s. Under these rights, all the water available in Landis
Creek has historically been diverted to irrigate 300 acres on Spring Valley Ranch. The water rights
include the Kendall and Stricklett Ditch, Forker and Gibson Ditch, Landis Ditch Nos. 1 and 2,
O.K. Ditch, and Frank Chapman Ditch. These water rights are all diverted at the same consolidated
point of diversion per the decree in Case No. 81CW193 (Exhibit C;[https://bit.ly/3uSH1O2]).
C. Wells and Springs.
The domestic in-house supply for the PUD will be provided by wells and springs. Spring
Valley Holdings has the right to use the following 33 wells and two springs:
Hopkins Spring Nos. 1 and 2
Spring Valley Well No. 1
Spring Valley Ranch Well Nos. 2-3
SVH Well Nos. 5-10
ASR Well Nos. 13-16
SVR Well Nos. 17-36
These structures were previously decreed individual conditional water rights in Case No.
98CW256 (Exhibit D; [https://bit.ly/3H0C87X]). During the Great Recession, Spring Valley
Holdings acknowledged that these structures could still be used pursuant to the augmentation plans
and change cases described below and elected not to undertake the expense ofpursuing water court
diligence findings for these rights, resulting in their cancellation.
Spring Valley Holdings recently filed an application in water court, Case No. 22CW3009, for
new conditional water rights for these structures to establish new priorities. A copy of the water
court application in Case No. 22CW3009 is attached as Exhibit E, [https://bit.ly/355jRJc].
D. Alternate Points of Diversion – Wells and Springs.
The wells and springs listed above operate as alternate points of diversion for the Basalt
Conduit water right under its 1957 priority through two water court decrees, Case Nos. 84CW212
and 98CW255, and Spring Valley Holdings’ Basalt District contracts. Case No. 84CW212
established nine wells and the springs as Basalt Conduit alternate points (Exhibit F,
[https://bit.ly/3gSEBGK]);and Case No. 98CW255 amended that decree to add 24 additional wells
as alternate points (Exhibit G, [https://bit.ly/3rWyK9K]).
Based on these decrees, when the springs and wells are out of priority, they operate under the
1957 Basalt Conduit priority. When the Basalt Conduit 1957 right is out of priority, the structures
operate under the augmentation plans described below.
Garfield County Community Development
Spring Valley Holdings Ranch PUD Phase 2 Final Plat Application
________________________________
Page 3 of 29
There are no other water rights in the Spring Valley Aquifer watershed with priorities senior
to the 1957 priority date of the Basalt Conduit water right. Thus, Spring Valley Holdings’ wells
and springs are only at risk of being out of priority vis-à-vis water rights on the Roaring Fork and
Colorado Rivers and those rights are protected from injury by releases under Spring Valley
Holdings’ Basalt District allotment contracts pursuant to the augmentation plans described below.
E. Augmentation Plans.
The augmentation plans decreed in Case Nos. 87CW155 and 98CW254 ensure that Spring
Valley Holdings can continue to provide water to the development even during calls by senior
water rights. Both augmentation plans use releases from Ruedi Reservoir or Green Mountain
Reservoir to address senior calls in an amount equal to out-of-priority depletions for in-house
domestic use, irrigation, and pond evaporation.
Case No. 87CW155.
The 87CW155 plan authorizes use for 2,642 residential units and 150 acres of irrigation. This
equates to 1,371 acre feet of diversions and 453.6 acre feet of depletions annually. A copy of the
87CW155 decree is attached as Exhibit H and available via this link [https://bit.ly/3rXxbZi]. This
plan only included the following structures:
Hopkins Spring Nos 1 and 2
Spring Valley Well No. 1
Spring Valley Ranch Well Nos. 2-3
SVH Well Nos. 5-10
Case No. 98CW254.
The 98CW254 plan supplements the 87CW155 plan allowing for additional irrigation and
adding new structures to supply the development’s water supply (See Exhibit I
[https://bit.ly/33ub977]). The decree adds ASR Well Nos. 13-16, SVR Well Nos. 17-36, ASR
Ditch No. 1, and treated effluent under the Spring Valley Sanitation District Pipeline right decreed
in Case No. 00CW21. The 98CW254 plan reduces the number of residential units to 577 (the
majority to be served by Spring Valley Sanitation District and 91 units to be on ISDS systems),
and increases irrigation from 150 acres to 420 acres.
The 98CW254 plan contemplates annual demand of 1,457 acre feet and depletions of 974
acre feet. Because much of the use will occur at times of free river when there is no senior call, the
augmentation requirement is only 420 acre feet. Importantly, the decree establishesthat the overall
uses at the development may be altered so long as the annual depletions do not exceed the
contemplated 974 acre feet. Thus, Spring Valley Holdings may modify the development plan
without having to modify or amend the existing water court decrees.
F. Treated Effluent – Spring Valley Sanitation District Pipeline.
Garfield County Community Development
Spring Valley Holdings Ranch PUD Phase 2 Final Plat Application
________________________________
Page 4 of 29
Spring Valley Holdings has the right to use treated effluent from Spring Valley Sanitation
District for golf course and open space irrigation. Spring Valley Holdings, Berkeley Family
Limited Partnership and Colorado Mountain College obtained a water right decree in Case No.
00CW21 for the Spring Valley Sanitation District Pipeline right to use treated effluent from the
wastewater treatment plant on their respective properties (See Exhibit J
[https://bit.ly/34TQYzY]).
In addition, by agreement, the Spring Valley Sanitation District must allow Spring Valley
Holdings to use the amount of treated effluent that corresponds to the amount of wastewater that
is generated within the Spring Valley Ranch PUD. A copy of this agreement is attached as Exhibit
K and available via this link [https://bit.ly/3LBuvZf]. This use is also augmented by the decree in
Case No. 98CW254. Using effluent would reduce demand for groundwater from the wells and
supplement aquifer recharge.
Depending on the feasibility of meeting regulatory requirements for using treated effluent, the
necessary infrastructure will be installed when there is sufficient effluent for irrigation to be
practical. If feasible in the future, Spring Valley Holdings intends to use treated effluent for
irrigation.
G. Reservoirs.
Spring Valley Holdings owns the water right for the Hopkins Reservoir for up to 119 acre
feet of storage. The reservoir has historically been used to control irrigation water for use on the
Spring Valley Ranch. Spring Valley Holdings has gone to great effort and expense to rehabilitate
the dam for the reservoir and has received approval from the Division of Water Resources for the
dam. Attached as Exhibit L [https://bit.ly/36rqqXz], is the Division of Water Resources’
Engineer’s Inspection Report from June 2021 which states that the reservoir may be filled to full
capacity. The reservoir will be used to supplement irrigation on the PUD.
In addition, Spring Valley Holding’s augmentation plans provide for three ponds to be built
on the property, ASR Reservoir Nos. 1-3, and augments a total of 24 acres of surface area
evaporation from those reservoirs. These reservoirs will be used to supplement irrigation and other
uses on the property. Spring Valley Holdings included claims for these three ponds for a total of
65 acre feet of storage in the recently filed 22CW3009 water court application.
H. Adequacy of Legal Water Supply.
Attached with this memo as Exhibit M [https://bit.ly/3HZ0mRb] is the analysis of Wright
Water Engineers from 2007 demonstrating that the water rights, plans for augmentation, and
change cases provide an adequate legal water supply for development of the entire PUD. The
report demonstrates that the legal water supply actually exceeds the demands for the 2007
development design. The development design has not changed since the time of the Wright Water
Engineers’ report.
As noted in the report, the projected annual water demand for the development is 717 acre
feet for potable use (in-house domestic and lawn irrigation) and 493 acre feet for non-potable use
Garfield County Community Development
Spring Valley Holdings Ranch PUD Phase 2 Final Plat Application
________________________________
Page 5 of 29
(golf course and open space irrigation and pond evaporation), for a total of 1,210 acre feet of
demand. The augmentation plan in Case No. 98CW254 authorizes diversions (i.e., demand) of up
to 1,457 acre feet which exceeds the contemplated demand.
The report also demonstrates that development depletions will be 141 acre feet for potable
uses and 404 acre feet for non-potable uses, a total of 545 acre feet. The 98CW254 plan authorizes
974 acre feet of depletions, much greater than what is required for the current PUD development
design. Based on the 2007 Wright Water Engineers’ report, the legal water supply for the entire
PUD is more than adequate and, therefore, for Phase 2, as well.
I. Phase 2 Development.
Phase 2 development will consist of 20 Cabin Lots, 26 Estate Lots, and 9 Ranch Lots, all
with single family residences. In addition, there are four Open Space Parcels, and one Light
Industrial Parcel. Water will be necessary to serve in-house domestic uses in fifty-five homes and
irrigation for residential lawn areas. No open space irrigation is planned at this time; however, this
may change as the developer provides landscaping along streets and public areas.
As detailed in the Wright Water Engineers’ 2007 report, Spring Valley Holdings’ water
rights, augmentation plans, and change cases are adequate to serve 192 Cabin Lots, 253 Estate and
Ranch Homes, 58 acres of lawn irrigation, and 120 EQRs for light industrial use. The 98CW254
augmentation plan authorizes 420 acres of open space irrigation. On that basis, Spring Valley
Holdings’ court-decreed plans for augmentation and changes of water rights, along with their
senior irrigation water rights provide a legally adequate water supply for the Phase 2 demands.
J. Phase 2 Supply.
Phase 2 will be supplied by two wells, ASR Well No. 16 and SVR Well No. 20. Both wells
were decreed as alternate points of diversion for the Basalt Conduit in Case No. 98CW255 and
both are augmented structures in Case No. 98CW254. ASR Well No. 16 is permitted to pump 100
gpm under Well Permit No. 86629F (Exhibit N, [https://bit.ly/3JCewby]). SVR Well No. 20 is
permitted to pump 300 gpm under Well Permit No. 86628F (Exhibit O,
[https://bit.ly/3gVSAM4]).
The permits for these wells allow use for 577 residential units, two 18-hole golf courses,
limited commercial development, and irrigation of 90 acres of lawns and gardens and 420 acres of
golf courses, open space, and agricultural areas. The well permits, therefore, authorize use of the
wells for the 55 homes, lawn irrigation, commercial use, and open space irrigation planned for
Phase 2.
K. Conclusion – Legal Water Supply.
Spring Valley Holdings owns water rights, court-decreed augmentation plans and change
cases, well permits, and water allotment contracts that provide an adequate legal water supply for
Phase 2 development. As noted in the 2007 Wright Water Engineers’ report, Spring Valley

Holdings’ water rights and water resources exceed the water requirements for the entire PUD,
including Phase 2.
II.Conditions of Approval.
Following are responses regarding the legal water supply related conditions of approval
contained in Resolution No. 2008-56 regarding Approval of a Preliminary Plan Application for
Spring Valley Ranch PUD recorded April 22, 2008 at Reception No. 747016, and Resolution No.
2010-38 regarding Approval for Spring Valley PUD recorded June 8, 2010 at Reception No.
786992. Each condition of approval is re-typed below in italics with the response following. The
numbers correspond to the numbering in the resolutions.
A. Resolution 2008-56 PUD Conditions of Approval, Reception No. 747016 (April 22,
2008).
20.0 Condition:With the exception of Lot P23 and OSR Parcel E, individual well
development shall be prohibited for new development.
Response: The Master Declaration of Covenants, Conditions and Restrictions for Spring
Valley Ranch P.U.D. recorded at Reception No. 793245, at paragraph 3.31, prohibit
development of individual wells except as set forth in the PUD Approval. A copy of the
CCR’s are included as Appendix K of the application.
21.0 Condition:The Applicant shall work with the water district providing potable
water service to the development to adopt a water usage rate structure that encourages
conservation.
Response: Spring Valley Holdings is committed to working with Landis Creek
Metropolitan District No. 1 to develop a rate structure that encourages conservation. The
Metro District is unable to develop a rate structure at this time since that will require the
District to undergo a rate study, first. The rate study will have to be based on the population
to be served, the overall uses of the water, and rates charged by other water suppliers in the
area at the time of service. Once the District has been able to undertake an appropriate rate
study, Spring Valley Holdings will work to have the District develop a structure that
encourages conservation.
22.0 Condition:Well water usage for agricultural and golf course purposes shall be
allowed to supplement surface water sources in the event of a shortage of surface water supplies.
Response: The water court decree issued in Case No. 98CW254 authorizes the use and
augmentation of well water to supplement surface water supplies for the entire 420 acres
of golf course, open space, and agricultural irrigation contemplated in the development
plan.

23.0 Condition:Valid well permits must be obtained for all of the wells included in the
water supply plan and copies submitted to the Planning Department prior to Final Plat approval.
Response: Spring Valley Holdings has valid production well permits for the wells that will
serve Phase 2, ASR Well No. 16 and SVR Well No. 20 (see Exhibit N,
[https://bit.ly/3JCewby]; and Exhibit O, [https://bit.ly/3gVSAM4]).
Spring Valley Holdings also holds valid production well permits for four other wells,
Spring Valley Well No. 1, Spring Valley Ranch Well Nos. 2-3, and SVR Well No. 17. See
Exhibit Q, [https://bit.ly/3sHFOpS].
B. Resolution 2010-38 PUD Conditions of Approval, Reception No. 786992 (June 8,
2010).
9.0 Condition:Future use of additional wells (Gamba wells) requires the development
of water rights and well permits if required by the appropriate state agency.
Response: There should not be need for more wells in addition to the 33 wells Spring
Valley Holdings currently has rights to develop, but, if there is, Spring Valley Holdings
will obtain the necessary water rights and well permits.
Spring Valley Holdings holds valid production well permits for the following six wells:
o Spring Valley Well No. 1 (Permit No. 86630-F)
o Spring Valley Ranch Well No. 2 (Permit No. 51363-F)
o Spring Valley Ranch Well No. 3 (Permit No. 86631-F)
o SVR Well No. 17 (Permit No. 86627-F)
o SVR Well No. 20 (Permit No. 86628-F)
o ASR Well No. 16 (Permit No. 86629-F)
See Exhibits N, O, Q.
Spring Valley Holdings’ consultantsestimatethatthesesixwells willprovidesufficient
physical supply for the entire PUD. For Phase 2, Spring Valley Holdings will use ASR
Well No. 16 and SVR Well No. 20. Based on the conclusions in the memo provided by
Roaring Fork Engineering, ASR Well No. 16 and SVR Well No. 20 produce sufficiently
to supply Phase 2. All six wells listed above operate pursuant to the plans for augmentation
and changes of water rights decreed by the water court in Case Nos. 84CW212, 87CW155,
98CW254, and 98CW255.
In addition to the six wells listed above, Spring Valley Holdings has the right to develop
and use 27 more wells to serve the PUD. If these additional wells are needed in the future,
Spring Valley Holdings has only to apply for well permits from the Division of Water
Garfield County Community Development

Resources and, because the wells are fully augmented pursuant to water court decrees, the
Division of Water Resources must issue the permits for all PUD uses.
There is no indication at this time that Spring Valley Holdings’ 33 wells and 2 springs
will be inadequate to physically supply the PUD; however, if, somehow, that becomes the
case, Spring Valley Holdings will apply in water court to add additional wells to the
structures in their existing augmentation plans and change decrees or will apply to change
the locations or diversion amounts associated with the authorized structures and obtain the
necessary well permits.
10.0 Condition:All conditions of the Division of Water Resources shall be met. Those
conditions include but are not limited to:
1.The claimed water rights are dedicated to the project; and
Response: The Landis Creek Metropolitan District Nos. 1 and 2 Service Plan establishes
that Spring Valley Holdings must provide the PUD water rights to the Districts for water
supply. See Exhibit R [https://bit.ly/3uZQcwg]. At the appropriate time, Spring Valley
Holdings will convey the water rights necessary for Phase 2 to Landis Creek Metropolitan
District No. 2 which will be the rights to ASR Well No. 16, SVR Well No. 20, and the
portions of the decrees issued in Case Nos. 84CW212, 87CW155, 98CW254, and
98CW255, and the senior ditch irrigation rights, that are necessary to supply Phase 2 uses.
2.The plan for augmentation is operated according to decreed terms and conditions.
Response: Spring Valley Holdings is committed to operating the decreed plans for
augmentation, all other water rights decrees, and all well permits according to their terms
and conditions as they are legally required to do. Spring Valley Holdings will not put the
development at risk of having the Division of Water Resources curtail diversions to the
water supply system by operating the water supply system contrary to the court decreed
terms and conditions.
11.0 Condition:Available surface water supplies shall be used to their fullest extent to
provide the irrigation supply to the golf courses in order to minimize groundwater withdrawals.
Response: Phase 2 does not include the golf course so this condition is not directly
applicable to the current application. Nonetheless, the Landis Creek Metropolitan District
Service Plan establishes that the surface water rights historically used to irrigate the
property (i.e., the ditch rights) must be used to irrigate the golf course. (Exhibit R, III.C.3
[https://bit.ly/3uZQcwg]). Spring Valley Holdings commits to using the surface water
rights as the primary source for golf course irrigation which is in the developer’s best
interest as surface water supplies will be less expensive to use than groundwater supplies.
Condition 11.0 (cont.):A groundwater monitoring plan shall be developed to monitor
future water levels near the Spring Valley Ranch wells. The monitoring plan shall include water
level measurements in the production wells and other wells at the PUD that can be used as
Garfield County Community Development
Spring Valley Holdings Ranch PUD Phase 2 Final Plat Application
________________________________
Page 9 of 29
monitoring holes. The monitoring plan shall include measurements made with enough frequency
to observe seasonal groundwater fluctuations and long term groundwater trends. Results of the
monitoring program shall be available to the public.
Response: Spring Valley Holdings provides a groundwater monitoring plan developed by
Zancanella & Associates included as Exhibit S and available via this link
[https://bit.ly/3556YPF]. Based on this plan, three existing wells will be used for
monitoring, ASR Well No. 15, SVH Well No. 6, and Monitoring / Observation Well No.
1. These locations were selected to monitor the aquifer on the upper bench and in the valley
floor, both near production wells and at a distance. Monitoring / Observation Well No. 1
is at least 2,000 feet from any production well location.
These monitoring wells will be outfitted with battery-operated transducers to take daily
water-level measurements. Baseline monitoring will start before development and before
production wells begin pumping. All production wells will also be monitored as they are
brought into production. For Phase 2, ASR Well No. 16 and SVR Well No. 20 will both be
monitored. All data will be stored with Landis Creek Metropolitan District No. 2 and will
be publicly available.
11.1 Condition:There will be an additional monitoring well developed or identified that is at
least 2000 feet from the production wells. Either a new well or an off-site well meeting those
criteria could meet the criteria. All of the monitoring reports will be available to the public.
Response: Well 03-2 identified in the groundwater monitoring plan is greater than 2,000
feet from ASR Well No. 16 and SVR Well No. 20, which are the wells that will be used
for Phase 2. As noted above and in the groundwater monitoring plan, all monitoring data
will be available to the public.
C. Conclusion.
Based on the responses above and the documents provided, Spring Valley Holdings has
complied with all the conditions of approval contained in the resolutions approving the PUD.

Dear Mr. Van Ardenne,
On June 21, 2021, representatives from our dam safety office completed inspection of
Hopkins Dam in accordance with Section 37-87-107 of the Colorado Revised Statutes; which
assigns to the State Engineer’s Office (SEO) responsibility for determining safe storage levels
for all reservoirs in the State of Colorado. I would like to thank Mr. Matt Weisbrod of
Zancanella & Associates for taking time to participate in the 2021 inspection.
Enclosed is a copy of the Engineer’s Inspection Report (EIR) and field photographs of the
referenced dam for your files. Please sign the signature block on page 4 of the EIR to
acknowledge your receipt of the report and return a copy to our office via electronic or regular
mail. If you have any questions regarding this EIR or require assistance with dam safety related

Re: Preparation of a Groundwater Monitoring Plan for the Proposed Phased
Development of Spring Valley Ranch.
Dear Martin:
Garfield County Resolution No 2010-38 has a requirement for a Groundwater
Monitoring Plan in paragraph 11.0 -11.1.
- 11.0 Available surface water supplies shall be used to their fullest extent to
provide the irrigation supply to the golf courses in order to minimize
groundwater withdrawals. A groundwater monitoring plan shall be developed
to monitor future water levels near the Spring Valley Ranch wells. The
monitoring plan shall include water level measurements in the production
wells and other wells at the PUD that can be used as monitoring holes. The
monitoring plan shall include measurements made with enough frequency to
observe seasonal groundwater fluctuations and long term groundwater
trends. Results of the monitoring program shall be available to the public.
- 11.1 There will be an additional monitoring well developed or identified that is
at least 2000 feet from the production wells. Either a new well or an off-site
well meeting those criteria could meet the criteria. All of the monitoring
reports will be available to the public.
Zancanella & Associates has reviewed the requirements and the wells for the property
and have developed a Groundwater Monitoring Plan to meet the requirements of Garfield
County. The groundwater monitoring plan is a phased approach that matches the phased
approach of the proposed development in the Spring Valley Ranch PUD, (SVR).

Garfield County requires, a monitoring well developed or identified at least 2000 feet from
the SVR production wells and water level measurement of the production wells at SVR.
The County requires that the wells be monitored at a frequency to observe seasonal
groundwater fluctuations and long-term groundwater trends.
For the Groundwater Monitoring Plan, we have identified three wells to be used for
baseline monitoring and long-term monitoring of the groundwater in the Spring
Valley Aquifer. Prior to any development of the SVR PUD, we recommend that the
identified monitoring wells have water level measurements taken at least monthly.
Baseline Monitoring:
To understand the current ground water levels in the Spring Valley area, baseline,
predevelopment measurements are needed. Three onsite SVR wells will be observed
during the period of pre-development. Once development starts, additional wells could
be brought online to measure and monitor the ground water levels if necessary.
The three wells that are proposed are: ASR Well No. 15, SVH Well No. 6, and
Monitoring2EVHUYDWLRQ Well 1R. These wells are illustrated on Figure 1 in Appendix
A with cyan labels. Below are the location of each of the proposed monitoring wells
and associated well permit numbers.
ASR Well No. 15 is located within the Spring Valley Ranch Property. This well is
located in the SWNE of Section 27, T 6S, R 88 W. The well permit associated
with this well is 36760-MH.
SVH Well No. 6 is located within the Spring Valley Ranch Property. This well is
located in the SWNE of Section 29, T 6S, R 88W. The well permit associated with
this well is 68889-F.
0RQLWRULQJ 2EVHUYDWLRQ :HOO 1R . Is located within the Spring Valley
Ranch Property. This well is located in the SWNE of Section 33, T 6S, R
88 W. The well permit associated with this well is 251164. Well 03-2,
wouldalsobe DQacceptable monitoring location on the southern property
boundary.
To monitor the wells before the development at SVR occurs, battery operated transducers
will be installed in the three designated wells. Long term permanent power will not be
available at these monitoring wells until production wells are brought online and water
diversions are required. The battery-operated transducers will be set to take a water level
reading at minimum of once a day at a consistent time. The transducers will be
downloaded a minimum of once every six months and processed. The data can then be
reviewed to track the groundwater fluctuations from the seasonal fluctuations and the
existing demands on the aquifer.
The importance of this baseline monitoring is to understand both the annual and the
seasonal groundwater fluctuations that are naturally occurring in the aquifer prior to the
Spring Valley Ranch development. The locations of wells were selected so that the

middle bench of Spring Valley Ranch and the lower bench of Spring Valley Ranch will be
monitored.
The well locations were chosen to be existing wells. These wells are situated in near
proximity to the proposed production wells and provide the 2000 foot spacing from other
production wells. This configuration allows for the monitoring of the direct impacts from
the production wells in proximity and the overall fluctuations in the aquifer.
Below is a brief explanation of what each well will monitor.
- ASR Well No 15. This onsite well is located on the middle bench generally in
the southern portion of the Spring Valley Ranch PUD. This well was historically
used to monitor other wells and is a good location to monitor the effects of the
production wells that are proposed on the middle bench of the SVR PUD.
- SVH Well No. 6: This onsite well is located on the lower bench of the Spring
Valley Ranch PUD. This well is centrally located along the western side of the
PUD and is in the proximity of potential production wells located on the lower
bench. This well location is proposed to monitor the aquifer water levels along
the western side of SVR.
- 0RQLWRULQJ2EVHUYDWLRQ:HOO1R. This on site well is located on the lower
valley near the southern HGJHRIWKH6SULQJ9DOOH\5DQFKSURSHUW\OLQH7KLVZHOO

Once the specified baseline monitoring points have been put into operations and the data
process, the information should be reviewed to determine if additional monitoring points
are needed or if current monitoring points need to be modified. Baseline monitoring points
should have the flexibility to change with proper justification. If it is found that the location
does not show connection to the aquifer or if there is too much interference from a well in
close proximity that will not allow for proper groundwater monitoring, a better location
within the same general area should be allowed. Care should be taken in moving and
adjusting monitoring well locations as shifting data points may not provide the monitoring
that is intended in this plan without additional baseline monitoring from the potential
relocated locations. The purpose of the monitoring program is to observe the impacts if
any with an open mind.
The Spring Valley Hydrologic System Report prepared by Gamba & Associates dated
March 10, 2000 is included in Appendix A. This report included exhibits of the underlying
geology in the Spring Valley area that was used to determine the locations of these
monitoring wells.

Production Well Monitoring:
The requirement to measure the water levels and the fluctuations in the production wells
will be implemented in a phased approach. The Spring Valley Ranch PUD is a multi-
phased development for the water system improvements and structures being built. We
recommend monitoring Production Well SVR Well No. 20 and Production Well ASR Well
No.16 first as they are identified as Phase 2 production wells. As additional production
wells are designated, water level and meter data will be collected concurrent with their
use.
With the development of the production wells, permanent monitoring devises with
production meters are recommended to be installed. The wells that are available to
supply the PUD are shown on the exhibit in Appendix A.
If the proposed production well locations are changed or additional production wells are
identified, the requirement to monitor carries to any future production well in the Spring
Valley Ranch PUD. If a well is permanently taken out of production, the monitoring
requirements shall not apply.
Additional Information:
As stated in the prior sections, baseline monitoring shall be installed and implemented
prior to the production wells coming online. All groundwater monitoring records will be
held by Landis Creek Metropolitan District No. 1 and will be available to the public.
Please do not hesitate to contact us with any questions pertaining to this plan.
Very truly yours,

Monitoring / Observation
Well No. 1
The purpose of this report is to examine geologic and hydrologic data related to the
geographic area known as Spring Valley and, there from, prepare estimates of the
potential specific yield of the water bearing horizons (aquifers) and estimates of amount
of annual recharge to those water bearing horizons.
A segment of the natural phenomenon that will be discussed in this dissertation is often
referred to as the “Spring Valley Aquifer”. This is the approximate 1,500-acre area
basin, flanked on the east by County Road 114 and on the north by County Road 115. It
has been penetrated by a number of wells that serve Colorado Mountain College, the sod
farm and most of the single-family homes along 114 road and 115 road. The small
stream that drains the surface of the basin, discharges in Red Canyon.
This basin, as noted above, represents only a segment of a dynamic hydrologic system
comprised of highly favorable geologic conditions situated in a meteorological
environment conducive to precipitation levels substantially greater than the adjacent
lower valley areas.
GEOLOGIC CONDITIONS
The recharge area of the Spring Valley Hydrologic System is comprised of approximately
15.4 square miles. This area, illustrated on the attached map, varies in elevation from
6,870 to 9,400 feet. The surficial geology of this recharge area may be divided, for
purposes of hydrologic consideration, into three petrographic types:
xSiltstones, sandstones, clay stones and conglomerates of the Pennsylvanian/
Permian Maroon Formation;
xBasalt flows, basalt talus, colluvium comprised predominantly of basaltic
material, all of Tertiary and early Quaternary age; and
xQuaternary lacustrine materials comprised predominantly of fine-grained products
of the chemical and mechanical weathering of the older rock materials that were
deposited in a lake. Samples from recent well drilling have been examined which
indicate deposits of volcanic ash in the lower portions of the lake basin.
Stratigraphically, the Maroon Formation under lays the basalt and alluvial materials. It
overlays the Eagle Valley Evaporate Formation, sometimes referred to as the Paradox
Formation. The Maroon formation, along with underlying sediments, was elevated and
exposed by erosion in the course of the orogeny that created the White River uplift to the
north.
The Eagle Valley Evaporite formation contains beds of soluble salts such as Gypsum and
Halite. The introduction of ground water into these salt beds resulted in the slow, but
steady solution and removal of several thousand feet of this formation over a large
section of a portion of the Roaring Fork River drainage area. The area of the Spring
Valley Hydrologic System straddles the northern edge of this affected area. As the salts
were removed, the overlaying rocks settled. This activity was, likely, very similar to the
current mining of soluble minerals by hydrothermal water as demonstrated by the
Glenwood Hot Springs and the other hot springs along the Colorado River. The solution
and removal of salts was not uniform over the effected area and the collapse of the
The Spring Valley Hydrologic System
March 10, 2000

overlaying rocks resulted in deformation, shear fracturing and faulting of the Maroon
formation as well as the overlaying rock of volcanic origin. The intensity of this
fracturing may be better understood by observing the Maroon Formation outcrops
exposed along Highway 82 from Carbondale to Red Canyon. The sandstone beds which
are interbedded with siltstones and shales are well-cemented, relatively hard rock. When
they were originally deposited and lithified, they formed straight, flat, continuous
unbroken layers of stone. Now they have the character of blocks of stone laid up in a dry
stack wall constructed on an uneven surface. While a minor amount of this fracturing
may be attributed to the White River Uplift activity, the vast majority is the result of
irregular collapse due to the solution mining of the underlying Eagle Valley Evaporites.
The volcanic materials were similarly fractured by this removal of the evaporite basement
rock. The fracturing of relatively continuous lava flows may be observed in the cliffs
along the lower reaches of Landis Creek and on the slopes northerly of county road 115.
The high infiltration rate and water bearing capacity of the volcanic rock material is the
product of the above noted, intense fracturing of the very brittle basalt coupled with the
high porosity of the subsurface beds and lenses of volcanic ash, cinders and breccias.
The strongest fault/fracture systems are indicated by geomorphologic evidence and are
illustrated on the map. It appears that most of the fracturing of the volcanic materials is
the result of bending and slumping of the rock layers which caused very little
displacement from one side of the fault/fracture zone to the other. Some of the volcanic
material outcrops and sub-outcrops are virtually rubblized while other outcrop sections
appear to be rafted basalt blocks with horizontal dimensions of several hundred feet.
Much of the land surface which slopes at 20% or greater has a very thin to virtually non-
existent soil cover. Vegetation, in these areas, is sparse and small indicating that it
survives with a minimal moisture supply, even though the area receives 25 to 30 inches
of precipitation per year. Excavation in the course of constructing pioneer roads reveals
areas of the subsoil rock, to be comprised primarily of medium sized to massive boulders
wherein the “porosity” may be visualized as that which would result from the stacking of
poorly sorted particles that range in size from basketballs to Volkswagens. The
percolation rate in these areas is obviously, very rapid.
In some areas of the surface, where the land slope is less than 15 percent, soil has
accumulated to depths of as much as 20 feet over the rock. Percolation tests were
conducted on soils of this type at 11 locations in the upland aquifer recharge area. The
average of the percolation rates measured was 25.5 minutes per inch (2.35 inches per
hour) with the range being from 3 to 64 minutes per inch. Of the 11 tests, 8 measured at
34 minutes per inch or less.
The volcanic activity events of 3 to 4 +/- million years ago deposited 100 to 200 feet or
more of interlayered basalt, cinders, ash, and breccias on a substantially more horizontal
surface than is present in the area today. The intervening 3 million +/- years of erosion
on that surface, which was slowly tilting southerly, has removed the softer,
unconsolidated cinders and ash from the surface, exposing, hard, weather resistant basalt.
The remaining, highly porous ash and cinder lenses below the hard basalt surface provide
pockets or constricted basins of high porosity where ground water is detained. Surface
The Spring Valley Hydrologic System
March 10, 2000

water is channeled into these detention basins or “hanging aquifers” via the fractured and
rubblized surface basalt. Subsurface fractures interconnect the detention basins and act
as restricted conduits that facilitate the slow, but continuous, transmission of water from
those at higher elevations to the ones below.
The segment of the system, which is referred to, as the Spring Valley Aquifer is in fact a
composite of a series of confined aquifers in the sediments overlaying the bedrock, and
the upper portion of the bedrock, underlying these sediments, which is itself, a confined
aquifer capable of, and demonstrated to produce artesian wells.
The confined aquifers within the lakebed sediments are comprised of sand and sandy
gravel horizons confined between layers of clay or sandy, gravely clay. From previous
drilling and data from Spring Valley Ranch well #6 drilled in February and March 2000,
it appears that the lower 70 to 110 feet of the sediment section in the northwestern end of
the basin is very fine-grained sand. Samples taken from this well drilling were tested and
it was determined that the specific porosity of this material is approximately 30%.
Microscopic examination of this material reveals that it is highly angular, with the
appearance of shattered glass. The particles do not exhibit the characteristics of sand
grains that have been subjected to significant transportation and attrition by either water
or wind action. It is suspected that this sand is vitric volcanic ash, which was deposited
in and adjacent, upslope of the lake basin during the creation of the basin by subsidence,
as discussed below.
The bedrock form of the lake basin is a “half graben” with the fault on the southerly side
along County Road 119. The bedrock is comprised of Maroon Formation sediments,
capped with 100 feet or more of volcanic material similar to that which may be observed
on the north side of 115 road and in the cap rock on the south side of the valley. This
bedrock block tilts, or more accurately “slumps” southerly From the divide between the
Colorado and Roaring Fork river drainages, down the south facing slopes of Spring
Valley and under the basin, to its termination at a fault that extends along the southern
side of the valley.
An additional feature has been observed in the aquifer basin. In many of the deep drill
holes, the volcanic rock section below is separated from the overlaying lake sediments by
a layer of blue gray clay as much as 40 feet thick. This is probably montmorillonite clay
of the bentonite variety that is formed by the alteration of volcanic ash and tuff. Where
present, this clay layer acts as a seal between the lake sediments and the underlying
volcanic rock material.
HYDROLOGIC CONDITIONS
The conditions and events noted above created the geologic setting for the Spring Valley
Hydrologic System. The other component of the system is the precipitation provided by
the meteorological environment.
Average annual precipitation in the Colorado Mountains increases substantially with
elevation. This is illustrated on the Colorado Average Precipitation Map, 1951 to1980,
prepared by Colorado State University in conjunction with Climatology Report 84-5,
The Spring Valley Hydrologic System

published by the U.S. Geological Survey. This map indicates that the uppermost part of
the recharge area of this hydrologic system receives an average of 30 inches of
precipitation per year while the lowest portion of the recharge area receives 16 inches to
20 inches per year.
PRECIPITATION INFILTRATION
The effective introduction of this precipitation into the underground hydrologic system is
largely dependent upon the character of the surface geology. Fractured basalt flows,
basalt talus and colluvium comprised predominantly of granular soil and rock are highly
permeable, wherein it is estimated that, at least 60% of the precipitation will enter the
aquifer after evaporation, transpiration and surface run-off. This high rate of infiltration
is graphically demonstrated by the drainage along County Road 115 within the Spring
Valley Ranch. The Basalt hillside northerly of the road ranges in slope from 10 to 40
percent. The average annual precipitation received by this area is 20 to 25 inches per
year. Drainage sub-basins above, discharge to these slopes, yet many of the natural
drainage swales crossed by the road do not have culverts and do not have the appearance
of areas that transport or pond water. It is reported, by longtime residents of the area, that
only on occasions of extremely high snow melt or cloud burst, does flooding of the road
occur.
This condition has also been observed on the pioneer roads constructed on the higher
portions of the Spring Valley Ranch that are underlain by fractured basalt or thin granular
soils over basalt. The inability of the thin soils to retain moisture is demonstrated by the
light vegetation cover.
The topographic characteristics of the highly basaltic surfaces are further evidence of its
high infiltration rate. This is an area that sustains an average precipitation of 20 to 30
inches per year on slopes of 10 to 50 percent. If the rate of infiltration of precipitation
was not exceptionally high, the large volume of high velocity run-off would have eroded
major drainage swales and gulches down the slopes, nearly perpendicular to the contours.
The precipitation does occur, but the run-off does not. Instead, this precipitation enters
the fractured and otherwise highly porous basaltic materials and is detained there in a
series of cascading aquifers that are interconnected by shear fracture zones. These
fracture zones function as control orifices and slowly release the gravity flow of water to
springs and the aquifers below.
Conversely, fractured Maroon formation overlain with silty, loam soils supporting
moderate to heavy vegetation will result in the infiltration of approximately 20% of the
precipitation with the balance being lost to evapotranspiration and surface runoff. Where
this surface runoff must cross the basaltic areas noted above, much of it will enter the
groundwater system.
The conditions described above were applied to the map of the recharge area, prepared on
the basis of published geologic mapping and personal observations. The following table
was prepared which estimates the average precipitation amount in the recharge area and
the potential infiltration amount entering the underground hydrologic system.

As may be observed, the above calculations indicate that more than 50% of the system
recharge occurs in the higher elevations. The possible amount of recharge to the aquifer
may also be estimated by the following formula:
recharge = precipitation – evapotranspiration – surface flow down red canyon.
Observations made by Wright Water Engineers, indicate that the surface flow down Red
Canyon will vary from 400 to 600 acre feet per year. As noted above, the estimated
average precipitation for the total system recharge area is computed to be 19, 908.2 acre
feet per year.
The following table illustrates an estimate of the probable losses to evapotranspiration in
the various precipitation zones and vegetation types. The evapotranspiration rate factors
used in the calculations were taken from Handbook of Applied Hydrology by Chow,
McGraw-Hill.

Appling the equation noted above:

Probable Recharge = 19,908.2 - 9,249.4 – 600 = 10,058.8 acre feet per year
The section underlain by basaltic materials located easterly of Landis Creek accounts for
the majority of the recharge and is believed to support the greatest detention volume in
the system, which, in turn recharges the Spring Valley Aquifer.

This belief is supported by the presence of consistently flowing springs which surface in
the upland area and the characteristics of the seven wells which have been drilled there
and pump tested . One well was drilled in the Maroon formation and six in the volcanics.
All of the wells were test pumped for 24 hours immediately following drilling and 3 were
selected for extended pump tests. The extended pump tests are described in the Wright
Water Engineers, Inc., report “Spring Valley Upland Aquifer Pumping Tests – 2000”.
Peter Cabrinha has been closely associated with the Spring Valley Ranch for 37 years and
has observed the performance of springs on the property. In a recent interview with Mr.
Cabrinha, the following observations were related:
xAll of the springs appear to flow year around at relatively consistent rates with the
exception of periods following extremely low winter and spring precipitation.
xIn his 37 years of observation, there were two occasions when the upper Landis
Creek springs, at 9,100 ft elevation, stopped flowing. These stoppages occurred
in the late summer or early fall of the year following the low winter and spring
precipitation. The springs resumed flow the following spring.
xThe flows of the lower elevation springs do not appear to diminish following dry
winter/spring seasons.
ESTIMATE OF SPECIFIC YIELD OF SYSTEM AQUIFIRS
In order to accommodate to the performance described above, the hydrologic system
must receive a substantial portion of the precipitation, as indicated in the table above, and
have a sufficient volume of specific yield to detain the infiltrated precipitation of several
years.
Information is available to compute a conservative estimate of the potential specific yield
of the aquifers in the system. The following assumptions and parameters will be used in
computing the estimated specific yield.
1.The upland area in the 20-inch to 30+-inch precipitation zone covered by volcanic
materials contains approximately 5,975 acres.
2.The thickness of the volcanic materials intercepted by the six wells, drilled in
volcanics, in the upland area ranged from 112 feet to 200 feet with an average of
168 feet. The depth of water in the wells (static level to bottom) ranged from 46
feet to 310 feet with an average of 135 feet. For conservative estimating
purposes, a saturated thickness of only 50 feet will be used.
3.The porous volcanic materials will perform similarly to sand, gravel and cobbles
for which the specific yield will range from 34% to 20% (from Figure 5-4 Bear
Jacob. 1979 Hydraulics of Groundwater. McGraw-Hill). For conservative
estimating purposes, a range of 10 to 20% will be used.
4.The surface area of the Spring Valley aquifer is approximately 1,500 acres.
5.Well log information indicates that the thickness of lake sediments may average
from 250 to 300 feet. in thickness, comprised of 10 to 20 feet of gravel bed, 140
to 180 feet of sandy, clayey silt with some gravel and 70 to 110 feet of very fine
sand (vitric volcanic ash). For conservative estimating purposes, the following
will be used for the lake sediments:
The Spring Valley Hydrologic System
March 10, 2000
Page 7 of 11
Sandy, clayey silt = 140 feet; gravel = 10 feet; very fine sand = 70 feet.
6.The specific yield of gravel beds in the lake sediments will range from 25% to
34%; the silty clay may range from 3% to 25%; the sand from 25% to 35% (from
Figure 5-4 Bear Jacob. 1979 Hydraulics of Groundwater.) McGraw-Hill). For
conservative estimating purposes, 25% will be used for the gravel beds and 3%
will be used for the clayey sediments and 20% for the very fine sand.
Bear Jacob. 1979. Hydraulics of groundwater. McGraw-Hill.
The following calculations of the specific yield of the aquifers in the hydrologic system
are based on the assumptions and parameters stated above.
Upland volcanic areas
5,975 acres x 50 feet thick x 0.10 or 0.20 specific yield = 29, 875 to 59,750 acre feet
Spring valley aquifer gravel beds
1,500 acres x 10 feet thick x 0.25 specific yield = 3,750 acre feet
Spring valley aquifer silty clay sediments
1,500 acres x 140 feet thick x 0.03 specific yield = 6,300 acre feet
Spring valley aquifer very fine sand bed
1,500 acres x 70 feet thick x 0.20 specific yield = 21,000 acre feet
Volcanics at base of Spring Valley aquifer
1,500 acres x 50 feet thick x 0.10 or 0.20 specific yield = 7,500 to 15,000 acre feet
ESTIMATED TOTAL SPECIFIC YIELD OF AQUIFERS IN
SPRING VALLEY HYDROLOGIC SYSTEM = 68,425 to 105,800 AF

Note: the above calculations do not include the volcanic areas in the 16” to 20”
precipitation zone nor any of the Maroon formation area.
ADDITIONAL AQUIFER CHARACTERISTICS
Examination of the records of the State Engineer indicates that the majority of the
domestic (single family home) wells in the Spring Valley are drawing water from the
upper to middle, silty, clayey lakebed sediments. Although the specific yield of these
materials is estimated to be only 3%, it is believed to be a viable segment of the aquifer
because it can provide adequate supplies of water to small domestic wells in the valley
bottom and probably not be effected by the pumping of large volume wells which draw
from the higher yield sands and volcanics in the lower section of the aquifer.
The large volume wells of CMC, Los Amigos and the sod farm are drawing water from
the volcanic material horizon at the base of the Spring Valley aquifer. Intermediate test
pumping of Spring Valley Ranch well #6 from the fine sand zone above the clay
indicates that sustained production of at least 250 gpm is available from this material.
The static head elevations of the CMC and Los Amigos wells, on the southeast end of the
valley, is approximately 100 feet lower than the Spring Valley Ranch wells on the
northwest end indicating a general flow of northwest to southeast. This would support
the theory that the aquifer outflow generally follows the half graben fault fracture system
to the roaring fork valley.
SUMMARY AND CONCLUSIONS
1.The source of recharge for the Spring Valley Aquifer is predominantly from the
volcanic material in the upland aquifers.
2.This writer believes the average annual precipitation entering the system as
recharge and flowing through the series of aquifers, to be approximately 10,000
acre-feet. Peer review of this information by others who have not had the benefit
of on-site observations, assign substantially higher volume to loss by
evapotranspiration and therefore estimate the average annual recharge volume
more conservatively at 4,700 acre-feet. Considering that the potential total annual
depletion of the aquifer by existing and future land development is in the vicinity
of 1,300 to 1,500 acre feet, the lower figure still assures viability of the aquifer.
3.The estimated specific yield volume of the aquifers in the hydrologic system is in
the range of 68,000 to 105,000 acre feet, of which approximately 38,000 to
46,000 acre feet are contained in the Spring Valley aquifer and approximately
30,000 to 60,000 acre feet are available in the upland volcanic material aquifers to
recharge the Spring Valley aquifer. These large volumes of stored water provide
a leveling effect to the variations in annual precipitation over a period of 6 to 10
years, or more.
4.A substantial portion of the water that enters the system does not again surface in
the system, but, leaks out through fracture systems associated with the half graben

fault on the south side of the Spring Valley aquifer and probably enters the
Roaring Fork River valley gravel aquifer.
5.The most promising target zones for a large production well appears to be the
volcanic ash layer in the lower sediments and the volcanic material horizon below
the sediments in the Spring Valley Aquifer.
6.It is highly probable that water production from the lower volcanic ash layer in
the sediments and the volcanic material horizon below the sediments in the Spring
Valley Aquifer will reduce the leakage to the Roaring Fork River area, but will
have little or no effect on the small domestic wells in the upper sediments or the
surface discharge down Red Canyon.
