I. INTRODUCTION
A. BASIS
This Water Supply Plan ("Plan") has been prepared in support of an application for PUD
Plan Review ("Rezoning") and Subdivision Review ("Preliminary Plan") for the proposed
River Edge Colorado ("Project", "REC", or "REC PUD") in accordance with the
requirements of the Garfield County Unified Land Use Resolution of 2008 ("ULUR"), as
amended. This Plan specifically addresses the requirements of Section 7-105 of the
ULUR, and along with the Water Treatment and Distribution System Design Report and
Raw Water Supply and Distribution Plan document that a water supply meeting the
criteria of 7-105 of the ULUR is available or can be designed and constructed to serve
the Project including adequate water supply. This Plan is supported by other referenced
documents submitted as part of the REC rezoning and preliminary plan applications
including the River Edge Colorado PUD and Subdivision Drawing Package ("Drawing
Package").
This Plan is designed to provide Garfield County with evidence that provision has been
made for an adequate water supply for the Project and. With respect to water delivery
within the Project Site (herein after defined), the design of the raw and potable water
treatment and distribution systems are documented in the Raw Water Supply and
Distribution Plan and Water Treatment and Distribution System Design Report which are
included as part of the REC rezoning and preliminary plan applications. The referenced
reports conclude that both a potable treatment and distribution system and raw water
distribution system can be designed and constructed to support the development of the
Project in accordance with generally accepted practices.
Once built, the potable water system will be dedicated to, owned and operated by the
Roaring Fork Water and Sanitation District ("RFWSD") or the REC Property Owners
Association, Inc. ("POA"). Potable water will be supplied from RFWSD water supply and
treatment facilities or a surface water intake located along the Roaring Fork River
adjacent to the Project Site. This Plan concludes that the either the RFWSD or POA
[under Carbondale Investments, LLC ("CI")] is capable of providing a potable water
supply adequate to support the Project. The raw water distribution system will be
owned and operated by the River Edge Colorado Property Owners Association, Inc.
(POA).
B. PURPOSE AND SCOPE OF REPORT
The primary purpose of this Plan is to provide evidence that provision has been made
for adequate water supply to serve the Project in accordance with Section 7-105 of the
ULUR. Adequate water treatment and distribution facilities are available to serve the
Project in accordance with Section 7-106.A of the ULUR as documented in the Water
Treatment and Distribution Design Report and Raw Water Supply and Distribution Plan
submitted concurrently with this Plan as part of the REC rezoning and preliminary plan
application.
Pursuant to Section 7-105, this includes the following:

Water Supply Plan
River Edge Colorado, Garfield County, Colorado
• An estimate of the water supply requirements for the proposed
development through build -out conditions;
• A description of the physical source of water supply that will be used to
serve the proposed development;
• A description documenting the ability of the supply to meet water
quality requirements;
• An estimate of the amount of water yield projected from the proposed
water supply under various hydrologic conditions;
• Water conservation measures, if any, that may be implemented within
the development;
• Water demand management measures, if any, that may be
implemented within the development to account for hydrologic
variability; and
• Proof of a legal water supply.
C. FINDINGS
Michael J. Erion, P.E. Resources Engineering, Inc. has conducted an assessment of the
water supply available to serve the Project in accordance with Section 7-105 of the
ULUR, and determined that the Project has adequate legal water and sources to support
the proposed development and irrigation demands. William S. Otero P.E. (Colorado
Registration #32163), in accordance with Section 7-106 of the ULUR, has conducted an
independent review of the water rights, Project demands and water treatment and
distribution facilities and determined that the Project can be adequately served by the
RFWSD or POA based on the general scope of the distribution system improvements
proposed within the Project as part of the Water Treatment and Distribution System
Design Report, submitted concurrently with this Water Supply Plan. William S. Otero
P.E. has further concluded that the raw water distribution system is adequate as
proposed in the Raw Water Supply and Distribution Plan to supplement the potable
water distribution system and meet the irrigation water demands associated with the
Project as required by the water rights adjudications proposed to meet the potable
water demands associated with the Project.
II. PROJECT LOCATION AND DESCRIPTION
A. PROJECT LOCATION
The Project is located along State Highway 82 ("SH 82") between the City of Glenwood
Springs and Town of Carbondale near the junction of County Road 110/113 ("CR 113")
and SH 82. The property is located almost entirely west of the Roaring Fork Transit
Authority ("RFTA") right-of-way and east the Roaring Fork River and the Roaring Fork
Conservancy ("RFC") Conservation Easement (i.e., Grant of Conservation Easement
dated February 3, 2000, recorded at Reception Number 559036 and survey map,
5
Water Supply Plan
River Edge Colorado, Garfield County, Colorado
recorded December 24th, 2008, recorded at Reception Number 760571 in the real
property records of Garfield County, Colorado). The Project straddles Cattle Creek which
is also located within the RFC Conservation Easement. A vicinity map is provided as
Exhibit 1 in Appendix Al. The Project covers approximately 160 acres ("Project Site") as
shown and described on the Project Site drawing [Exhibit 2(a -d), Appendix Al].
B. PROJECT DESCRIPTION
The Project is a proposal to create a walkable clustered -form of residential development
with neighborhood amenities including naturalized open space and enhanced wildlife
habitat, community recreation, parks, and neighborhood agriculture that is designed to
serve the residents and preserve and provide reference to the rural character and
agricultural roots of the Roaring Fork Valley. The Project aims to have a strong historic
identity back to the days of 'old Colorado' when compact neighborhoods formed with a
strong sense of community based on the land and surrounding landscape. The REC
landscape aesthetic will be simple, informal, and place emphasis in the use of plant and
landscape materials local, adaptable and appropriate to the climate and environment of
the area. The Project will include approximately 366 residential units of various sizes
and types including 55 affordable homes and one exclusive executive lot for a custom
home. Housing types will range from attached homes to small single family attached
and detached garden homes, village homes, and larger estate homes. Smaller garden
homes are anticipated to be designed for younger residents that are looking for their
first home in the County, while village homes and estate homes will provide move up
opportunities for growing families. Densities in the Project are proposed at less than 21A
units per acre. Lot sizes will vary from over 1 acre to approximately 5,000 square feet for
single family homes, and 1,700-5000 square feet of lot area for each garden home. Most
of the units back to either proposed active parks or reclaimed open space to help
enhance the connection to the land. The REC layout and design is depicted in the PUD
Plan, PUD01-03 Series and the Preliminary Plan PRPN01-03 Series of the Drawing
Package.
The architectural theme will be complementary to the traditional architecture of the
valley. Generally, exterior materials will include wood, stone, brick, stucco and cement
board siding. Varied roof heights and articulation of the front elevations will be used to
break up the massing and provide street -level appeal. Front porches and covered stoops
are included on homes to emphasize the entry and connection to the sidewalk and
street. Roofing will include dimensional shingles, metal, or other materials appropriate
to the building style and that roofs will generally be pitched. Gables, wall plane and
roofline articulation, bays, balconies, porches, canopies and arcades will be used in the
design of various buildings. The selection of materials will minimize the exterior
maintenance of the homes to help maintain a quality appearance for the long term.
The street pattern and pedestrian network are designed to facilitate community
interaction. Streets have detached sidewalks with designated cross walks at major
intersections and landscaped areas that create a comfortable environment for walking.
On -street parking in most areas will further buffer vehicular and pedestrian uses.
Internal circulation is maximized and dead-end streets are limited. Alleys are used
where appropriate to enhance the streetscape and achieve a mix of housing styles. A
6
Water Supply Plan
River Edge Colorado, Garfield County, Colorado
soft trail system is used to connect open spaces and other common elements with the
sidewalk network. The homes are placed close to the streets to help define the
streetscape space and provide visual interest to pedestrians. Street trees and plantings
are proposed to enhance the aesthetics of the street.
The community is served with a variety of recreational facilities and a neighborhood
center that could include meeting room(s), fitness room, offices, kitchen, restrooms,
recreational facilities, and limited community service use such as a day care facility,
deli/coffee shop, or health club. Parks will provide informal recreational opportunities
within the community and will likely include tot lots, playfields, and trail system. The
west portion of the property is generally set aside as the naturalized area that buffers
the RFC Conservation Easement along the Roaring Fork River. The soft trails around the
property allow residents to enjoy the river and wetland areas without disrupting the
environment in conformance with the terms of the RFC Conservation Easement. More
than the minimum open space requirements will be met by the project. Nearly 50% of
the Project Site is in some form of open space, common area or park. Finally,
opportunities for productive and edible landscapes, including community gardens and
neighborhood orchards are integrated and dispersed in between the residential land
uses as gathering and focal places for residents connecting REC to its agricultural
heritage.
The combination of trails, recreation areas, and open space system with the ability to
engage in 'interactive community agriculture' on a small scale will make REC a very
desirable place to live, filling a unique niche not yet met in Garfield County. This unique
combination will help establish a sense of place, foster community, and engage
residents with their immediate environment. It is intended this overall outdoor focus
will set the tone and become a major driver of the identity of REC.
III. EVIDENCE OF ADEQUATE WATER SUPPLY
The following is drawn from a letter report prepared by Water Resources Engineer
Michael J. Erion, P.E. of Resources Engineering, Inc. ("Resources Engineering Report")
which presents the water rights and water supply plan for the Project (Appendix B).
A. WATER SUPPLY REQUIREMENTS FOR THE PROJECT THROUGH BUILD -OUT
CONDITIONS
1. POTABLE WATER DEMAND
The potable water demand includes the indoor demand associated with 366
residential units, a neighborhood center of up to 10,000 square feet and 20,000
square feet of utility facilities. This equates to 366 EQRs (Residential
Equivalents) for residential uses and 9 EQRs associated with non-residential uses
for a total of 375 EQRs. An EQR represents 350 gallons/day in demand. The
resulting potable water demand is shown in Table 1 of the Resources
Engineering Report (Appendix B) is 163 acre feet.
Water Supply Plan
River Edge Colorado, Garfield County, Colorado
2. RAW WATER DEMAND
The raw water demand includes both the outdoor residential and community
space demands for irrigation water between April and October. The outdoor
irrigated area is assumed to be 83 acres of permanent irrigated area and
supplemental water for up to 109 acres during periods of revegetation of
disturbed areas. Many of these areas are naturalized spaces which will not
receive irrigation water on an ongoing basis. The estimated water demand for
permanent irrigation as shown in Table 1 of the Resources Engineering Report
(Appendix B) is 190 acre feet. Supplemental water demand associated with
revegetation of disturbed areas is estimated at 249 acre feet. It should be noted
that the permanent irrigation areas are shown at buildout conditions and that
supplemental water is no longer demanded at that time. So the amount of
water demanded is not totally cumulative. As areas are developed,
supplemental water is decreased accordingly. As a result, there are never more
than approximately 150 acres under irrigation at any one time during
development.
B. PHYSICAL SOURCE OF WATER SUPPLY
1. POTABLE WATER
The potable water supply will be provided by the RFWSD alluvial wells located in
the Aspen Glen and Coryell Ranch subdivision and surface diversions from the
Roaring Fork River using the Robertson Ditch Rose Ranch Enlargement, Posy
Pump and Pipeline (Iron Bridge Subdivision), or the RBC Roaring Fork Diversion
(REC) water rights if the development is served by the RFWSD. If served by the
POA, the potable water supply will e met by a surface water diversion at the
RBC Roaring Fork Diversion (REC). Resource Engineering, Inc. notes that the
yield of the physical water supply from the RFWSD alluvial wells and from the
Roaring Fork River are not affected by dry year hydrologic conditions. The RBC
Roaring Fork Diversion was appropriated for a flow rate of 1.25 cfs for domestic
and municipal purposes including fire protection and irrigation.
2. IRRIGATION WATER
The physical source of water will be from the Roaring Fork River via diversion
into the Glenwood Ditch and from Cattle Creek via diversion into the Staton
Ditch. The Glenwood Ditch has decreed water rights totaling 50 cubic feet per
second (cfs). CI owns 24.47% of the Glenwood Ditch decree equating to
approximately 12.23 cfs. Historically, the Glenwood Ditch has had a full water
supply, even in critically dry years.
The Staton Ditch diversion from Cattle Creek averaged 900 acre feet per year. CI
owns 4.69 cfs of the 5.18 cfs of decreed Staton Ditch water.

River Edge Colorado, Garfield County, Colorado
C. ABILITY OF THE SUPPLY TO MEET WATER QUALITY REQUIREMENTS
1. POTABLE WATER
Potable water will be supplied by the RFWSD water distribution system from
sources at their current alluvial wells or surface water diversions of the Project
is served by the RFWSD. These sources and the treatment/ distribution system
currently meet drinking water quality standards. If it is determined that surface
water sources are necessary either through a supply from the RFWSD or POA,
the surface water sources will be treated to drinking water standards utilizing a
water treatment plant to be located on the Water and Wastewater Utility Tract
(Tract AO or AR) within the Project Site. The treatment methods are discussed in
the Water Treatment and Distribution Design Report, which accompanies this
Plan as part of the REC rezoning and preliminary plan application. No specific or
unusual treatment issues associated with utilizing the Roaring Fork River as a
source are anticipated.
2. IRRIGATION WATER
The current source of irrigation water is anticipated to require basic filtering
prior to distribution through the raw water irrigation system. The treatment and
distribution system is discussed in the Raw Water Supply and Distribution Plan
that accompanies the REC rezoning and preliminary plan applications. Cross
connection controls and education/signage are important in ensuring the
proper use of the irrigation water and limiting potential effects to users caused
by improper use.
D. ESTIMATED YIELD UNDER VARIOUS HYDROLOGIC CONDITIONS
As discussed in the Resource Engineering Report, the sources of supply do not appear to
be effected by drought conditions.
E. WATER CONSERVATION MEASURES
In house water conservation measures are not specifically proposed as part of the
Project although low flush toilets and showerheads may be required. However,
landscape plans are dominated by native and low water use species to reduce outdoor
demand while maintaining a comfortable environment for residents. It is anticipated
that the waterwise landscaping approach utilized will result in reducing demand by
nearly at least twenty-five percent of that projected in Appendix B. In addition,
community areas will be watered utilizing advanced temperature and precipitation
sensitive irrigation systems to limit water supplies to the optimal supply based on
landscape type and soils.
Finally, household use of raw water will be controlled through an incentive -based water
rate policy that provides highly competitive water rates based on the water demands
associated with the desired landscape forms with rates exponentially increasing above
the desired application rates. This method, while not fully constraining the water
demand, will result in reduced application rates and better landscape selection. It is
9
Water Supply Plan
River Edge Colorado, Garfield County, Colorado
anticipated that these rate measures could reduce application rates by as much as
fifteen percent of those estimated to determined irrigation demand.
F. WATER DEMAND MANAGEMENT MEASURES
Water demand management measures will be consistent with any demand
management strategies implemented by the RFWSD or State of Colorado. No specific
additional measures are proposed within the Project. As noted by Resources
Engineering, Inc., the water supply sources have limited risk with respect to yield as a
result of hydrologic conditions including the most severe droughts historically measured
in the region.
G. PROOF OF A LEGAL WATER SUPPLY
1. POTABLE SUPPLY
As documented in the Resources Engineering Report, the legal water supply for
the potable water system is based on the water court decrees in Case No.
01CW187, 07CW164 (pending) and 08CW198 (pending). In Case No. 01 CW187,
a legal water supply for 349.55 EQR's and 3 acres of irrigation was adjudicated.
The decree utilizes 62.6 acre feet of BWCD contract water for diversion at the
RFWSD Aspen Glen Well Nos. 1-7, Coryell Ranch Well Nos. 1-14, and the Coryell
Ranch Roaring Fork Diversion. The pending decree in Case No. 07CW164
provides for an additional 850.45 EQR's and 4 acres of irrigation to be diverted
from the RBC Roaring Fork Diversion (River Edge Colorado), Well Field (River
Edge Colorado) as well as the Robertson Ditch, Posy Pump and Pipeline, and the
existing RFW & SD wells. The pending decree in Case No. 08CW198 provides for
the 349.55 EQRs and 3 acres of irrigation to be diverted at the additional points
of diversion identified in Case No. 07CW164. River Edge Colorado has amended
BWCD Contract No. 381 for a total of 74.9 acre feet as required for all three
water court decrees.
The three decrees and the BWCD contract provide a legal water supply for 1,200
EQRs and 7 acres of irrigation, which is more than adequate for the proposed
375 EQRs and up to 7 acres of irrigation.
2. IRRIGATION WATER
Also as documented in the Resources Engineering Report, the Glenwood Ditch is
decreed for 12.23 cfs for irrigation uses and Staton Ditch is decreed for 4.69 cfs
for irrigation uses. The water court Case No. W-2206 for the Unocal Sanders
Ranch determined that the historic consumptive use is 439 acre feet on 260
irrigated acres of which the Project Site represents approximately 150 acres of
the total irrigated areas. REC will require approximately 83 acres of permanent
irrigation and 109 acres of temporary (3 to 5 years) irrigation. The senior
irrigation water rights owned by REC are more than adequate for the proposed
Project's raw water irrigation requirements.

IV. ADEQUATE CENTRAL WATER DISTRIBUTION SYSTEM
The distribution and treatment systems are discussed in the Potable Water Treatment
and Distribution Design Report and Raw Water Supply and Distribution Report
submitted concurrently with this Plan as part of the REC rezoning and preliminary plan
applications. Both reports document the feasibility of serving the Project with water
meeting the requirements of the ULUR.

RE: River Edge Colorado — Water Rights and Water Supply Plan
Dear Rocky:
January 17, 2011
This letter report presents the water rights and water supply plan for the proposed River Edge
Colorado project south of Glenwood Springs, Colorado. The plan described herein addresses the
standards outlined in Section 7-104 and 7-105 of the Garfield County Unified Land Use
Resolution of 2008 (ULUR), as amended. It is the opinion of Resource Engineering, Inc.
(RESOURCE) that the proposed project has an adequate physical and legal water supply as
described below.
PROJECT DESCRIPTION AND PLAN SUMMARY
The proposed River Edge Colorado project includes 366 residential lots, a neighborhood
commercial center with up to 10,000 square feet of building space and 20,000 square feet of
utility facilities. The legal water supply is based on water court decrees for the property
adjudicated in Case Nos. 01CW187, 07CW164 (pending), and 08CW198 (pending) and senior
irrigation water rights. The potable water supply will come from the existing and pending water
court decrees to supply the in-house demands from the project and up to 7 acres of outside lawn
and landscape irrigation. The outside irrigation will primarily be supplied by a raw water irrigation
system using the Glenwood Ditch and Staton Ditch water rights historically used on the property
and owned by the Applicant. Fire protection will be provided through appropriate storage facilities
and fire hydrants on the central potable water system.
WATER DEMAND
The 366 residential lots represented 366 Equivalent Residential Units (EQR's) of water demand.
The 10,000 square feet of community building space and the utility facilities are estimated to have
9 EQR of demand. Each EQR includes 350 gallons per day of in-house use and up to 5,000
square feet of irrigation for single family units. This equates to 42 acres of irrigation. However,
the project will limit potable water irrigation to a maximum of 7 acres for areas that are not easily
served by the raw water irrigation system. The annual potable water demand for 375 EQRs and
7 acres of irrigation is estimated at 163 acre feet and the annual depletion is 20.2 acre feet.
The raw water irrigation system is proposed to serve most of the outside irrigation demand.
Approximately 83 acres of permanent irrigation is estimated for the project. The annual demand is
estimated at 190 acre feet for permanent irrigation. An additional 109 acres of temporary (3
years to 5 years) irrigation for revegetation and establishment of native trees, shrubs, and
grasses is anticipated for the project. Up to an additional 249 acre feet of water may be needed
in some years for temporary irrigation.
The estimated total water demand for the project is 353 acre feet per year plus up to an additional
249 acre feet for temporary irrigation. The total annual depletions for the project are estimated at
172 acre feet plus up to 199 acre feet for temporary irrigation. The estimated demand and
depletion for the potable system and raw water irrigation system are shown on the attached Table
1.

PHYSICAL WATER SUPPLY
Potable Water Source
The proposed potable water source will be a surface diversion (infiltration gallery) from the
Roaring Fork River and may include the existing RFW & SD alluvial wells, wells on the River
Edge Colorado project, and surface diversions using the Robertson Ditch Rose Ranch
Enlargement and/or the Posy Pump and Pipeline. The River Edge Colorado water right is known
as the RBC Roaring Fork Diversion and is pending in Case No. 07CW164. The RBC Roaring
Fork Diversion was appropriated for a flow rate of 1.25 cfs for domestic and municipal purposes
including fire protection and irrigation.
River Edge Colorado may include the project into the Roaring Fork Water & Sanitation District
(RFW & SD) and connect to the existing RFW & SD system. All of the above mentioned sources
of water may be used by the RFW & SD to serve the project.
The potable water system must comply with the CDPHE drinking water standards. The Roaring
Fork River and alluvial well water quality is suitable for and can be treated to meet potable
drinking water standards.
The yield of the physical water supply from the Roaring Fork River and alluvial wells is not
adversely affected by dry year hydrologic conditions. The average daily flow of the Roaring Fork
River at Glenwood Springs is approximately 1,300 cfs and the minimum daily flow in an extreme
drought year is approximately 250 cfs. Adequate water supply can be obtained from the river and
wells. The engineering reports by 8140 Partners, LLC provide details concerning the adequacy of
the potable water delivery system in accordance with Section 7-106 of the ULUR.
As mentioned earlier, the project will minimize use of potable water for irrigation to conserve the
treated water supply. The project also includes other water conservation measures such as low
water use vegetation and low flow water fixtures. RESOURCE's opinion of adequate water supply
is not dependent on and did not consider water conservation measures.
Raw Water Irrigation Supply
River Edge Colorado will provide a raw water irrigation supply for most of the project area. The
physical source of water will be from the Roaring Fork River via diversion into the Glenwood Ditch
and from Cattle Creek via diversion into the Staton Ditch (or an alternate point of diversion from
Cattle Creek on property owned by the Applicant). The Glenwood Ditch has decreed water rights
totaling 50 cubic feet per second (cfs). The Applicant owns 24.47% of the shares in the
Glenwood Ditch Company, equating to 12.23 cfs. Historically, the Glenwood Ditch has had a full
water supply, even in critically dry years. A review of diversion records shows an average
diversion of approximately 15,000 acre feet per year and a dry year diversion of 22,000 acre feet.
The Applicant's share of these diversion are 3,700 acre feet per year and 5,400 acre feet in dry
years.
The Staton Ditch diversions from Cattle Creek averaged 900 acre feet per year. The Applicant
owns 4.69 cfs of the 5.18 cfs decreed to the Staton Ditch. Together with the Glenwood Ditch,
these water rights have historically irrigated 260 acres on the Applicant's property. There has
always been an adequate physical supply to meet the full irrigation demand on the property.
River Edge Colorado does not anticipate the need for any water conservation or water demand
management measures due to variations in hydrologic conditions.

LEGAL WATER SUPPLY
Potable Water System
The legal water supply for the potable water system is based on the water court decrees in Case
Nos. 01CW187, 07CW164 (pending) and 08CW198 (pending). In Case No. 01CW187, a legal
water supply for 349.55 EQR's and 3 acres of irrigation was adjudicated. The decree utilizes 62.6
acre feet of BWCD contract water for diversion at the RFW&SD Aspen Glen Well Nos. 1-7,
Coryell Ranch Well Nos. 1-14, and the Coryell Ranch Roaring Fork Diversion.
The pending decree in Case No. 07CW164 provides for an additional 850.45 EQR's and 4 acres
of irrigation to be diverted from the RBC Roaring Fork Diversion (River Edge Colorado), RBC
Well Field (River Edge Colorado) as well as the Robertson Ditch, Posy Pump and Pipeline, and
the existing RFW & SD wells.
Finally, the pending decree in Case No. 08CW198 provides for the 349.55 EQRs and 3 acres of
irrigation decreed in Case No. 01CW187 to also be diverted at the RBC Roaring Fork Diversion,
RBC Well Field, Robertson Ditch and the Posy Pump & Pipeline identified in Case No. 07CW164.
River Edge Colorado has amended BWCD Contract No. 381 for a total of 74.9 acre feet as
required for all three water court decrees. The three decrees and the BWCD contract provide a
legal water supply for 1,200 EQRs and 7 acres of irrigation, which is more than adequate for the
proposed 375 EQRs and up to 7 acres of irrigation.
Raw Water Irrigation
The Glenwood Ditch is decreed for 50 cfs and the Staton Ditch is decreed for 5.18 cfs for
irrigation uses. The Applicant's interest in these ditches has been used to fully irrigate 260 acres
on the property throughout the irrigation season. The proposed River Edge Colorado project will
require approximately 83 acres of permanent irrigation and 109 acres of temporary (3 to 5 years)
irrigation. The senior irrigation water rights owned by River Edge Colorado are more than
adequate for the proposed project's raw water irrigation requirements.
