I. RELATIONSHIP TO THE COMPREHENSIVE PLAN
The proposed PUD is located District 1C -Central Water and Sewer, Severe Environmental
Constraints as indicated on the Comprehensive Plan Management Districts Map.
II. DESCRIPTION OF THE PROPOSAL
A. Site Description: The proposed PUD is located on a bench overlooking the Roaring
Fork river valley floor, directly above the existing Westbank development. Topography
on the site consists of three distinct geologic configurations: a moderately sloping
lowland fully vegetated with native grasses, a steeply sloped zone sparsely vegetated
with evergreen species, sagebrush, and native grasses, and an upland benched area well
vegetated with significant sagebrush, rabbitbrush, and isolated stands of pinion and
juniper.
Several intermittent drainages are visible in the steeper portions of the property and
extend into the upland bench. Elevations on the property range from 5,950 at the
northern edge, to almost 6,880 feet at the southern reaches of the property. A vicinity
map is shown on the cover sheet of the plans submitted prior to the previous hearing.

B. Background: Westbank Filing #4 was approved and platted in September of 1982. In
April of 1993, the applicants proposed revisions to the 1982 approval, but withdrew the
application based on comments from the Planning Commission. Table 1 summarizes
the 1982 approval, the April 1993 submittal, and the current proposal.

Since that 1982 approval, the Subdivision Improvements Agreement (SIA) has been
amended in respect to two dates: the deadline for improvements has been changed from
November 1, 1984 to November 1, 1994; and the deadline for security for the
improvements described in the SIA has been extended from July 1, 1983 to July 1, 1993.
These amendments were made in response to a public meeting to consider the
revocation of the approval of Filing #4 in March of 1992, due to the failure to complete
any of the required improvements on the site.
Since the 1993 SIA security date has past, the Board has the authority to revoke the
PUD, which would return the property to its underlying zoning (A/R/RD). No action
has been taken by the Board at this time.
C. Development Proposal: The current proposal includes 63 single-family lots and one
multi -family fourplex for a total of 67 dwelling units. A zone district map and site plan
were included in the previous staff packet.
The approved plan anticipated an expansion of the existing water system which
currently serves Westbank Filings 1, 2 and 3. The current proposal includes a separate
system, with water to be provided from new well(s) to be augmented with Ruedi
Reservoir water. A total of 40 acre feet of water is to be purchased from Ruedi for the
needs of the development. Fire protection will be provided via hydrants and a storage
system. No hydrant locations or infrastructure details are included with this submittal.

III. REVIEW AGENCY/PUJBLIC COMMENTS
A. Colorado Geological Survey: The Colorado Geologic Survey has reviewed the project,
and conducted fieldwork on July 13, 1993 (see letter on paged . Based on their
review, the areas of significant hazards have been avoided, although the "safe build"
areas on lots 1, 2, 35 and 43 are relatively small. The Geologic Survey also "strongly
concur with CTL/Thompson that each lot and building site be investigated by a
qualified engineering geologist and/or soils and foundation engineer...". Costs
regarding maintenance costs for the roads and infrastructure will be higher than typical
subdivisions. The feasibility of ISDS was also questioned, and a central sewer was
mentioned as a preferred alternative. In conclusion, Geologic Survey states that ..."the
project is feasible, but only with careful planning down to the siting of homes on lots."
A Reconnaissance Geologic Investigation (CTL/Thompson, Inc. June 24, 1993) is
included as Exhibit G of the application.
The primary conclusions from the CTL/Thompson report are as follows:
• "Preliminary foundation recommendations and construction criteria can only
be determined from more detailed, site specific surface and subsurface
investigations and analysis" (p.1);
•
"Areas mapped as Qsl (Slide Deposits) on the site include medium to large
slump features and failures of colluvial slopes. These areas appear fairly stable
but will become unstable if disturbed" (p.6);
"None of the geologic conditions found are considered to be sufficiently
hazardous to prevent development of the project as proposed, however,
potentially hazardous geologic conditions must be properly planned for during
site development" (p.7);
• "We recommend that detailed, site specific soils and foundation investigations
be performed for each residence built in this development" (p.7);
• "Development in areas of potentially unstable slopes or immediately adjacent
to steeper slopes along the lower edge of the upper terrace should be avoided"
(118);
• Drainage and ravines on the site present moderate potential hazard from flash
flooding and low potential from debris flow. We recommend determining the
100 year flood plain (which will be a part of the site drainage plan) and avoid
development in those areas" (p.9).
B. Colorado Department of Health: Staff contacted Mr. Dwayne Watson, who concluded
that the project was not located within a 201 planning area. No written comments have
been received to date from the Colorado Department of Health. Based on Mr.
Watson's conclusion, there does not appear to be any statutory constraint to ISDS.
C. Colorado State Forest Service: The Colorado State Forest Service reviewed the
previous submittal, and conducted fieldwork on April 1, 1993. The proposed
subdivision is in an area that has been mapped as medium to high hazard for wildfire.
The Forest Service was particularly concerned with areas in the subdivision where
grades exceed 30 percent and the densely vegetated drainages.
Forest Service standards require dual ingress/egress points, which are not included in
the proposal. The proposed cul-de-sac far exceed the 750 foot maximum length as
recommended by Forest Service standards. Turnouts are recommended at 750 intervals
to provide adequate emergency vehicle access. Mr. Roger's suggested that structures
not be located in or at the head of drainages. A copy of Kelly Roger's April 7, 1993
letter included in the application as Exhibit I.
• •
D. Carbondale and Rural Fire ProtectionDistrict. Ron Leach visited the site on April 29,
1993, and his comments are included in the application as Exhibit I. Mr. Leach
concluded that the wildfire danger was "low", conflicting with the conclusions of the
Forest Service.
E. U.S. Bureau of Land Management: The BLM has submitted a letter dated July 30,
1993, reiterating their past comments (see letter on page Zvi.2'/). Primary concerns
noted in their letter of April 2, 1993 included the following:
1. The BLM recommended fence standards that allow for easy passage by big
game;
2. The parcel immediately adjacent to the site has been identified as a disposal
parcel, and is not expected to remain in public ownership;
3. The density proposed by the applicant will render the critical mule deer habitat
unsuitable for deer habitat, and will increase deer impacts on adjacent property,
particularly during the winter months;
4. The soils on the site are poorly suited for housing development due to shallow
depth to bedrock, steep slopes, and very high hazard of water erosion.
A copy of Michael Mottice's April 2, 1993 letter is attached on page 4 5--
F. Public Service Company: No response has been received from Public Service.
G. Colorado Division of Wildlife: The Division of Wildlife has reviewed the proposal, and
had the following comments (see July 27, 1993 and April 1, 1993 letter on pages
1) The area is considered to be elk winter range and critical deer habitat, meaning
that the loss of critical winter habitat would adversely affect deer in the area.
2) DOW further states that big game populations in the area will be threatened by
domestic dogs, loss of native vegetation, increased erosion, increased vehicular
traffic, increased human/wildlife interaction, and migration obstacles. The
DOW suggests the following mitigation:
A) Reduce the density by cluster development;
B) Require underground utilities to protect raptors;
C). Require fencing restrictions;
D) Restrict or prohibit domestic dogs and horses within the subdivision;
E) Restrict building envelopes to preserve native vegetation.
In addition, the DOW suggests that all homeowners are aware of the critical habitat
designation, and realize that deer and elk will die on the property, and are responsible
for disposing of carcasses.
The July 27, 1993 correspondence from DOW, based on a review of the updated
submittal, indicated that the Division stands by their previous comments. They also
suggest that dogs be limited to 1 per dwelling unit, that physical kennels are more
effective than the proposed electric fences, arid offered additional fencing suggestions.

In response to DOW concerns, the applicants have prepared dog restrictions, based on
previously approved subdivisions in Garfield County. A copy of these proposed
restrictions are included in the application, beginning on page 7.

I. Office of the State Engineer, Division of Water Resources: The State Engineer's Office
has reviewed the application, and had the following comments (see letter on page

2) The protective covenants should include language concerning the management
and responsibility of the wells and water system and define the amount of
allowed irrigation.

IV. STAFF COMMENTS
This application is requesting approval for a PUD amendment and sketch plan review. These
two processes require compliance with different standards, and each is addressed below
separately.
1. PUD REZONING REQUEST: Westbank Filing #4 was processed as a PUD, with the
existing portions of Westbank processed as a subdivision request. The standards for the
current proposal (Zone District Amendment) are addressed in Section 4.0 of the Zoning
Resolution.
PUD Objectives: A PUD may be approved by the County Commissioners for the
following purposes and to achieve the following objectives:
1. To provide necessary commercial, recreational, and educational facilities
conveniently located to housing;
2. To provide well -located, clean, safe and pleasant industrial sites involving a
minimum of strain on transportation facilities (NOT APPLICABLE);
3. To insure that the provisions of zoning laws which direct the uniform treatment
of dwelling type, bulk, density, and open space within each zoning district will
not be applied to the improvement of land by other than lot -by -lot development
in a manner which would distort the objectives of the zoning laws;
To encourage innovations in residential, commercial and industrial
development and renewal so that the growing demands of the population may
be met by greater variety in type, design, andlayout of buildings and by the
conservation and more efficient use of open space ancillary to said buildings;
5. To encourage a more efficient use of land and of public services, or private
services in lieu thereof, and to reflect changes in technology of land
development so that resulting economies may inure to the benefit of those
needing homes;
• 13'
• •
6. To lessen the burden of traffic on streets and highways;
7. To conserve the value of land;
8. To provide a procedure which can relate the type, design, and layout of
residential, commercial, and industrial development to the particular site,
thereby encouraging preservation of the site's natural characteristics; or
9.
To encourage integrated planning in order to achieve the above purposes and
objectives of development.'
In the application, the applicant desire to modify several provisions of the approved
PUD because the "it is felt that the density of lot of the original plan in keeping with
development that has occurred in the general area (sic)".. and "the difficulty of
permitting and constructing sewage treatment facilities which would discharge to the
Roaring Fork River has caused the construction of central sewage collection system to
be impractical." 2
Staff notes that the purpose of a PUD is not to perpetuate adjacent development, but
rather to give the developer the opportunity to be innovative in design beyond the
traditional subdivision process. Staff will defer to the Planning Commission regarding
compliance with these objectives, based on a comparison with the approved project.
Consistency with the General Plan: Section 4.04 requires that "No PUD shall be
approved unless it is found by the County Commissioners to be in general conformity
with the County's General Plan". Comments regarding applicable portions of the
Comprehensive Plan are as follows:
Housing: The overall goal of the housing section of the Comprehensive Plan is as
follows:
Provide for affordable and diverse housing types capable of accommodating the needs
of County in allincome ranges, without putting a financial burden on existing
public services.'
Objective #3 calls for the promotion of a variety of housing types and mix through the
use of a flexible development review process. Policy #3 states that the PUD process is
encouraged, so that the development community has greater flexibility in project
design.4
In staffs opinion, the cluster concept proposed in the 1982 approved project is more in
line with the housing goals described earlier than the current application, although a
single, four unit fourplex is included in the development. In addition, the applicants are
proposing duplex lots as a conditional use. The duplex concept, although commendable,
has some technical flaws, discussed in detail on page 9 of the Staff Report. Staff

concedes that the concept of "affordability" is difficult to define, although the term
"variety" is more applicable for comparative purposes.
Recreation and Open Space: Policy 5 requires that areas such as floodplains and
geological unstable soils which are restricted for the building of habitable structures will
be used as common open space accessible to the public in new developments.'
Additional geologic data has been provided by the applicant and lot configurations
have changed based on these constraints. The CTL/Thompson Report indicated that
"Development in areas of potentially unstable slopes or immediately adjacent to steep
slopes should be avoided".6 As shown on the Geologic Hazard Map, (Sheet 18), areas
of unstable slopes are included within platted lots, and are not dedicated to the public.
It does appear, however, that building envelopes are available on each lot.
The 1982 approved project is clustered, and areas having considerable environmental
constraints are zoned open space.
Transportation: Policy 5B requires that excessive road cuts that will create negative
visual impacts will be discouraged.' The proposed road alignment crosses numerous
drainages, and the applicant has verbally indicated that nine (9) different alignments
were contemplated, and the current proposal represents the option having the least
visual impact.
Water and Sewer Services: Objective 3 encourages developers to carefully analyze the
site's capability to accommodate individual sewage disposal when it is being considered
as a part of a development proposal. Policy 3A states that the County will require
developers proposing ISDS to provide information that demonstrates to the County
that the land involved can physically accommodate the individual systems.'
The original proposal, and the Geologic Report prepared in 1976, did not address the
feasibility of ISDS on the site due the proposed central sewage system. Percolation test
have been performed at four locations on the site, as indicated on the Drain Plan Map
(Sheet 5). Soil Conservation Service mapping indicate that 8 soil groups are located on
the property. The four percolation tests were located within the Gypsum-Gypsiothid
Complex (#55), Urraca Moist-Mergel Complex (#109), Empedrado Loam (#35) and
Almy Loam group (#6). These soil groups represent the areas most likely to have ISDS,
and all had acceptable percolation rates.
The 1982 approved project includes a central sewer option.
Environment: Objective 1 discourages the development of land in areas of identified
severe environmental constraints. Policy 1, designed to implement this objective,
requires that the County shall discourage and reserve the right to disapprove (sic)
development in areas with identified severe environmental constraints such as active
landslides, debris slides, unstable slopes, bedrock slides, major mudflow, radioactive
tailings, slopes over 25 percent and 100 year floodplain. Objective 5 requires projects
ensure that development on land having moderate or minor environmental constraints
consider the limitations of the land.9 Objective 6 requires that development proposals
consider soil constraints as a part of the physical design, and policy 6 requires that the

County discourage development in areas with severe soil constraints. Objective 9
encourages development in areas with the least environmental constraints prior to land
with the greatest physical limitations.10
The CTL/Thompson Geologic Report included with this submittal includes identified
constraints on the property (sheet 18). Identified hazards include unstable slopes,
potentially unstable slopes, flash flood hazard, accelerated erosion areas and
debris/mudflow hazards. The development has concentrated the majority of
development in areas outside of known geologic risks. However, large portions of lots
Lots 52, 53, 54, 55, 56, 57, 58, 59, 60, 62 and 63 are in an identified flash flood hazard
area. No mitigation has been proposed for this identified hazard.
Performance Standards: The Comprehensive Plan includes a series of performance
standards addressing specific environmental constraints, including areas having slopes
greater than 25 percent. The Plan states that slopes exceeding 25 percent may be:
1. Maintained as open space;
2. Platted as a portion of an approved building envelope, with an open space
easement;
3. Platted as a portion of a building lot which as adequate usable building space
available other than steep slopes;
4. Platted as a portion of a subdivision and dedicated as permanent open space;
5. Developed with special design considerations and engineering.1'
Slope analysis for each lot is shown on sheet 2 (Preliminary Plan Lot Layout and
Dimensions). All lots have at least one (1) acre of buildable space less than 40 percent.
2. ZONING REQUIREMENTS. Section 4.08 addresses the PUD processing
requirements, and the following discussion addresses specific requirements that must
be been met by the application:12
1. Under provisions of Section 4.08.05(2)(h), the applicant is required to identify
sites suitable for construction, as well as sites suitable for sewage disposal based
upon the limitations described in the soils report. As described earlier, this area
has significant slope and soil constraints. The applicant has agreed to provide
building envelopes for each lot as a condition of approval. As noted earlier,
percolation tests have been performed for the site. Results were consistent with
Colorado Department of Health and Garfield County standards.
2. Under provisions of Section 4.08.05(7)(E)(i), the a.pplicant is required to
identify the proposed water source adequate to serve the PUD. The proposed
water source are wells augmented by Round II sales from Ruedi Reservoir. It
is not clear that such water contracts are currently available, or whether the
amount identified by the applicant is adequate to support a well servicing the
PUD;
3. Under provisions of Section 4.08.05(7)(E)(ii), the applicant must describe the
proposed method of sewage treatment. In regards to sewage treatment, the

I 'b"
• 1
Department of Health has previously noted the difficulties of the system
proposed in any area with soils that may not be appropriate for ISDS, and
slopes that may not accept ISDS. On-site percolation tests performed by the
applicant have indicated that ISDS is feasible on the site.
4. Under provisions of Section 4.08.05(7)(E)(iii), the applicant must describe the
general manner in which storm drainage will be handled. Exhibit H of the
application includes drainage basin calculations for culvert sizing. As shown
on Sheet 18, a significant portion of the northern lots on the lower bench are
within an area defined as a "flash flood hazard", assumed to originate from the
drainage basin during a 100 -year storm event. No mitigation for this hazard
has been presented by the applicant, or a justification for the lots proposed for
the area. Staff suggests that this be a condition of approval;
5. Under provisions of Section 4.08.05(7)(F)(iv), the applicant must address legal
access to the site. Garfield County Road Standards allow cul-de-sacs that do
not exceed six hundred feet (600') in length. The Board of County
Commissioners may approve longer cul-de-sacs for topographic reasons and it
can be proved that fire protection and emergency access is provided.13 The
longest cul-de-sac within the PUD extends from Native Lane to its terminus, a
distance of approximately 3,695 feet in length, with no alternative access. The
Fire District has apporved the excessive length (See exhibit I of the application).
6. Under provisions of Section 4.08.05(7)(G), the applicant must provide evidence
that the PUD has been designed with consideration of the natural environment
of the site and the surrounding area and does not unreasonably destroy or
displace wildlife, natural vegetation, or unique natural or historic features. The
current plan, based on documentation from the Division of Wildlife cited
earlier, will displace wildlife. Dog restrictions have been submitted, although
less stringent than DOW are suggestions that applicant has included drainage
easements to serve as wildlife corridors. Staff discussed the effectivenessof the
corridors with Kevin Wright (DOW), who concluded that the corridors will
have no impact on the reduction of critical habitat in the ares. Staff suggests
that DOW recommendations be a condition of approval.
3. PROPOSED ZONE DISTRICTS. The application includes the following zone
districts within the PUD: Residential Single Family District (R/S.F.),
Residential Multi -Family Fourplex District (R/M.F.4), Residential Duplex
District (R/M.F.2) and Open Space. The zone district map (Sheet 3) includes
two additional zone districts: Greenbelt, Drainage and Parks and "Bikepath".
The applicant has agreed to include these districts within an overall Open Space
District with language included in the zone district text permitting such uses.
Staff also suggested that the bikepath be relocated to County Road 109 frontage
on the east end of the property. The applicant has agreed to this suggestion.
One significant change has been the applicant's proposal to include duplexes as
a conditional use within a Residential Duplex District (R/M.F.2). No maps
have been submitted in regards to this proposal. This zone district would allow
a duplex as a conditional use if an owner has title to two adjacent lots.
Although the additional multi -family lots are consistent with Comprehensive
Plan policies, staff has identified the following issues surrounding this proposal:
• Garfield County has no provisions for denying a Conditional Use, only
placing conditions on the application. This is significant in that it gives
13Garfield County Subdivision Regulations, Section 9.33(A), page 9-2.
• I 14°
• •
little or no control regarding the location of the proposed duplexes.
Quite simply, ownership of two adjacent lots would be the only
conceivable requirement to obtaining approval. This would have
significant impact on the land use assemblage within the PUD;
• The conditional use contemplated, described on page 4 of the updated
zone district submittal (attached on pages ), has a restriction
that reads as follows: "The construction of a duplex on any two
adjoining lots will not be permitted without the owner showing
reasonable proof that such development will not adversely affect the
adjacent lot owner's view." What constitutes a "view" is not defined,
and may be too ambiguous to enforce in an equitable fashion.
• Since no map was submitted indicating the location of the "duplex"
zoning, it is unclear what the intention of the applicant was in
contemplating such a district. Since the only requirement is the
ownership of adjacent lots, it appears that the only possible
configuration of such a zone would encompass the entire PUD. Based
on this assumption, it appears that what is contemplated is traditionally
referred to as an "overlay zone".
Staff suggests that if duplexes are intended within the PUD, that they
be included as a Special Use within the previously defined single-family
zone district. This would allow the County to deny such an application
if it was deemed inappropriate by the County Commissioners on a case-
by-case basis. Without such a change, a duplex could occur anywhere
in the subdivision without any concern for basic subdivision design
concepts originally contemplated by the developer, and the County
would have no basis for denial under the Conditional Use Permit
process. Staff suggests that very specific standards for denial or
approval be developed in regards to duplexes within the project.
V. STAFF RECOMMENDATION
The primary issue in front of the Planning Commission centers on the differences between the
approved PUD zoning and the current proposal. In staff's opinion, the approved project is
superior to the current proposal in the following respects:
• The central sewer is consistent with Colorado Department of Health and State Geologic
Survey suggestions. Staff recognizes that the financial commitment for central sewer
is significant, although financial feasibility is not a criteria addressed in the Garfield
County Subdivision Regulations or Zoning Resolution.
The approved project is based on a cluster concept, focussing development activities in
areas with the least environmental constraints, retaining open space adjacent to existing
development in Filings #1, #2 and #3, and limiting impact to critical wildlife habitat;
• The scope of the multiple -housing proposed in the original PUD is more consistent with
the goals and objectives of the Comprehensive Plan.
Staff concedes that the proposed project is feasible from an engineering perspective, although the spirit
and intent of PUD regulations does not rest completely on engineering criteria.
If the Planning Commission feels the applicant has addressed the issues raised at the last public hearing,
and additional issues can addressed at Preliminary Plan, the following conditions of approval are
offered as a starting point:

Re: Westbank Ranch PUD Filing No. 4, Preliminary Plan
Dear Mr. Michaelson:

Michael B. Long
Division Director
Vicki Cowart
State Geologist
and Director
GA -94-0001
At your request and in accordance with S.B. 35 (1972), we have
reviewed the materials submitted for and made a field inspection on
July 13, 1993, of the site of the proposed residential subdivision
referenced above. The following comments summarize our findings.
(1) Generally, the assessment of potential geology -related problems
in this subdivision presented in the analysis by CTL Thompson is
thorough and adequate. Although there are some parts of the project
area that have moderate to severe geologic hazards, these will be
adequately avoided of the subdivision is developed as shown on the
proposed plat. The lot sites are sufficiently large that a safe
building site can be selected on each one although such "safe
build" areas on some of the lots are relatively small, especially
on lots 1 and 2 and lots 35 to 43, inclusive.
(2) We strongly concur with the recommendation by CTL Thompson that
each lot and building site be investigated by a qualified
engineering geologist and/or soils and foundation engineer who
should collaborate with the architect for proposed structure(s).
Careful siting of structures, proper control of drainage, and
properly designed building foundations (including their concrete
specifications) will be critical to minimizing construction and
maintenance problems for future homeowners in the area.
(3) It is likely that maintenence costs for roads and other
infrastructure in the subdivision will apt to be higher than that
typical of subdivisions in more gently sloping and less hazardous
terrain. The County should evaluate these costs for any facilities
Mr. Dave Michaelson
July 21, 1993

rYI
that may be dedicated to it for maintenance, e.g. roads.
(4) The feasibility of use of individual sewage -disposal systems on
lots of this size, in terrain which is relatively steep in many
places, and where bedrock is at or near the surface is highly
questionable. The admission in the submitted documentation (p. 2,3)
that a "replacement" leach field site should be planned for on each
lot is an indication that the proponent is considering the
possibility that individual septic systems will eventually fail. It
is our opinion that the subdivision should be placed on a central
sewer system served by its own sewage- treatment plant. Eventually,
when it is economically feasible to join a larger sewer district
(possibly the proposed Aspen Glen facility), this subdivision
should do so. Minimizing duplicity of sewage -treatment facilities
is a policy of the Colorado Department of Health, Water Quality
Control Division.
In summary, this project is feasible, but only with careful
planning down to the siting of homes on lots. Some of the project
area that must be used for locations of roads, utility corridors,
and other infrastructure is geologically hazardous and will
necessitate higher than ordinary maintenance and repair costs. The
sizes of lots and geologic conditions make the feasibility of use
of individual sewage -treatment systems questionable.
Sincerely,
mes M. Soule

In response to the request for comments regarding the proposed Westbank Ranch
P.U.D.-Filing #4 Subdivision, I offer the following statements for your
scheduled April 5, 1993, Planning Commission hearing. Proposed lot 91 is the
only parcel adjacent to public land.
1. The landowners should be aware of the location of property boundaries to
ensure no encroachment occurs on public land. Should fence construction be
considered along the BLM boundary, the fence standards should allow for easy
passage by big game, i.e. less than 42" in height with a 10" kick space
between the top 2 wires.
2. The parcel of BLM administered land adjacent to lot 91 has been designated
as a disposal tract in the BLM's Resource Management Plan. Current or future
owners of this lot 91 should not expect the BLM tract to remain in federal
ownership.
3. Rocky Mountain Natural Gas Company is proposing to construct a pipeline
near or within the 100 foot Public Service Company utility easement depicted
on the sketch plan. Any utilities proposed for the subdivision that cross
public land would have to obtain a right-of-way from this office.
4. The adjacent public land is not allotted for livestock grazing.
5. Adjacent public land is open to hunting. The proponent should be aware
that such recreation uses are allowed on BLM-administered .land.
6. After review of our mineral survey notes, there are no federal minerals
located within the subject private lands.
7. Development of this nature, especially at the density proposed, would
likely render the critical winter mule deer habitat (which is in relatively
poor condition) unsuitable for deer use. The development could increase deer
use on adjoining public and private lands particularly during the winter
months.
Garfield Planning - Page 2
8. The soils within the proposed subdivision are poorly suited for housing
development due to shallow depth to bedrock, steep slopes, and very high
hazard of water erosion.
We appreciate the opportunity to comment on this proposal. If you have any
questions or need additional information, please contact Jim Byers in this
office at 945-2341.

I refer you to our 4/1/93 letter to you regarding wildlife impacts to mule
deer and elk by the proposed Westbank Ranch Filing #4 Resubdivision. We stand
by our recommendations in that letter regarding ways to minimize those
impacts.
In addition to those recommendations, we recommend the following:
1. If dogs are allowed, restrict to 1 dog/home. All kennels be
constructed before C.O. is issued. Based upon our experience, electric
fencing does not always work; a physical kennel is preferred.
2 Any rail fencing be 48", 3 -rail or less with at least 18" between 2 of
the rails.
The following issues did not appear to be addressed the last submission:
1. Density was reduced; however building envelopes were not designated. We
would recommend these be placed in the nearest 1/3 of each lot closest
to roadways and set back from any hillside. If possible clump
homesites.
2 All utilities be buried.
3 No horse/livestock grazing. If allowed. homeowner fence haystacks with
8' fencing to prevent damage to haystacks which is an attractant to big
game.
4. Maintain native vegetation outside building envelope.
5. Winter kill animals and their disposal.
Thank you for the opportunity to comment. If you have any questions, please

RE: Westbank Ranch Filing 94 Resubdivision
Dear Dave:
REFER 10:
On Hatch 26, 1993, district wildlife manager Kevin Wright and I
visited Westbank Ranch Filing 04 to review the site for wIl.dlife
values. We observed about twenty live deer browsing, three
carcasses of deer lost during this winter, heavy utilization of
sagebrush and rabbitbrush plants by big game, heavy use of grails
into and out of the area and concentrations of pellet groups
along ridge tops. Division of Wildlife mapping places Westbank
Ranch Filing 04 in elk winter range and in critical deer_ habitat
(meaning that loss of this critical winter range would adversely
affect deer).
Development of Westbank Ranch Filing 04 will stress big game
populations because of increased domestic dogs running at large,
loss of native vegetation, increased erosion, increased vehicular
traffic, increased human/wildlife interaction and increased
obstacles to negotiate such as fencing.
We would like to recommend the following methods of minimizing
impacts to current wildlife occupants:
1. Reduce the density of 98 single family homesites by the
use of fourplex lots, duplex lots, clumping homesites,
and/or eliminating some lots or combining lots into larger
lots.
2. Require underground utilities to protect raptores (birds
of prey) from electrocution. (A pair of golden eagles nest
very close to this development.)
3. Require fencing restrictions. No wire fences. Wood and
wood rail fences a maximum height of 48 inches with a
maximum of three rails (allows for fawns to pass between
rails) except for solid privacy fences which should he a
minimum of. 72 inches.
4. No dogs allowed.

5. No livestock allowed on any lot. (Livestock, especially
horses on small dryland lots denude native vegetation,
increase erosion and increase wildlife damage to neighboring
property owners from wildlifes attraction to hay fed to
livestock.)
6. Restrict building of any structure to the third of each
lot nearest the roadway. (This would help reduce loss of
native vegetation.)
7. Require the developer to include the following
information to buyers of each lot:
A. These homesites are located in critical deer and
elk winter range. Taller browse plants such as
sagebrush, oakbrush, mountain mahogany, servl.ceberry
and bitterbrush usually protrude through the winter
snows and are important to the survival of big game.
Homeowners are encouraged to maintain native
vegetation.
B. Deer and elk can damage or destroy ornamental
plantings. For suggestions to prevent wildlife damage
and types of ornamentals less susceptible to damage,
contact the Colorado Division of Wildlife.
C. Death is natures way of keeping wildlife in balance
with the amount of remaining habitat-. Wildlife
mortality rates are increased by human and pet
interaction with wildlife. DEER AND ELK W.ILI. DIE ON
YOUR PROPERTY. It is the landowners responsibility to
dispose of the carcass. Burial on your own property or
disposal at a landfill is acceptable.
Thank you for the opportunity to comment. We are available to

Water Division 5, Water District 38
Dear Mr. Michaelson:
oy Romer
Governor
Ken Salazar
Executive Director
D. Simpson
Slate Engineer
Thank you for the referral concerning the amendment to the Westbank Ranch Filing #4.
The project is located approximately five miles south of Glenwood Springs along Highway 82. The
change includes downsizing the project from 98 dwelling units to 67 dwelling units. In addition,
instead of expanding the existing water supply, the modified plan anticipates a separate water
distribution system from eight proposed wells. Out -of -priority depletions are proposed to be
augmented with releases from Ruedi Reservoir. All lots will have non -evaporative septic systems.
We can recommend approval for the preliminary plan only. Prior to approving a final plan
for this project, the following issues must be addressed:
• A court approved water supply plan must be decreed. The applicant has filed a plan for
augmentation, Case 93CW104, which has not been adjudicated, yet. If the applicant wishes
to be covered under the West Divide Water Conservancy District substitute water supply
plan while proceeding with the Court process, the applicant must conform with the
parameters of the District's plan.
• The Protective Covenants should include specific language concerning the management
and responsibility of the eight wells in the central water supply system; the amount of
irrigated acreage each lot may have; the amount of livestock allowed per lot; and that all
lots must use a non -evaporative septic system. All these conditions will be stipulated in the
final decree. Because the augmentation plan is still pending, additional conditions may be
imposed when the plan is decreed.
Our April 13, 1993 letter to the County for the modification to Westbank Ranch Filing #4
was in response to a change from a multi -family to single family concept. The proposed water
supply was from four decreed wells. Our April letter does not apply to this submittal.
Should you have further questions or comments regarding our concerns for the water supply
for this project, please contact me at the above address.

WESTBANK RANCH PLANNED UNIT DEVELOPMENT MODIFICATION
AND
WESTBANK RANCH FILING #4 RESUBDIVISION
Submitted for review by the Garfield County Planning Commission at the Preliminary
plan hearing on 9 August 1993
In accordance with Section 4.12 of the Garfield County Zoning Resolution of 1978
and amendments thereto through 14 October 1991, the owners of the WESTBANK
RANCH PLANNED UNIT DEVELOPMENT desire to modify several provisions of the
plan. The modifications are being proposed because it is felt that the density of lot
of the original plan in keeping with development that has occurred in the general area.
Additionally, the difficulty in permitting and constructing sewage treatment facilities
which would discharge to the Roaring Fork River has caused the construction of a
central sewage collection system to be impractical. The modified concept provides
lots with sufficient space for a Targe single family home and onsite sewage treatment
facilities to serve it. The lots are configured to take advantage of the natural views
of the area. The development layout includes common open space which will be
dedicated to the homeowners association.
The proposed Westbank Ranch Filing #4 Resubdivision is illustrated on the following
drawings:

THE PROPOSED MODIFICATIONS TO THE EXISTING PUD PLAN ARE AS FOLLOWS:
1. Dwelling Type and Number
The current plan contains 10 fourplex lots, 10 duplex lots and 38 single family lots for
a total of 58 lots with 98 dwelling units.
The modified plan contains 63 single family lots and one multi -family, fourplex lot for
a total of 67 dwelling units.
2. Lot Size
The current plan contains lots ranging from 0.44 acres to 1 .94 acres, with 36 of the
58 lots being less than one acre.
The modified plan contains lots ranging from a minimum of 1.0 acre to 14.26 acres,
with the majority of lots in the 2.0 to 3.0 acre range.
3. Site Plan
The current plan calls for 81 dwelling units on the upper bench and 17 on the lower
bench.
The modified plan (see map) calls for 51 single family dwelling unit Tots on the upper
bench and 13 lots on the lower bench. Of these 13 lots, 12 are for single family
dwelling units and one (number 64) is a multi -family, fourplex lot. In addition, it is
proposed that duplex units may be permitted on any two adjoining lots, subject to a
conditional use permit being granted by the County, and the conditions listed here
under "B. Uses, conditional".
4. Domestic and Irrigation water Supply
The current plan anticipates expansion of the existing water system which serves
Westbank filings I through III.
The modified plan anticipates a system separate from the existing Westbank system,
with water to be supplied from new well(s) to be drilled and augmented with Ruedi
Reservoir water for which a contact has been obtained. A total of 40 acre feet of
water is to be purchased from Ruedi Reservoir for the needs of the development. As
a part of the water system development, sufficient irrigation water will be provided to
allow for each residence to irrigate up to 2,500 square feet. Fire protection storage
and hydrants will be incorporated in the domestic water system. A letter report and
documents related to the purchase of water from Ruedi Reservoir are attached as
EXHIBIT E.
5. Sewage Disposal
The current plan anticipates the construction of a central sewage collection system
and treatment plant.
PAGE 2
• •
The modified plan anticipates the use of individual, onsite sewage treatment and
disposal systems. Each lot will be designed to accommodate the space necessary for
a leach field disposal system as well as space for a second, "replacement" field.
Percolation rate tests were conducted at four separate sites on the property which
were representative of the soil condition of the development. The locations of the
tests are illustrated on the RECONNAISSANCE GEOLOGIC MAP. The results of these
tests are as follows:
Test # 1
Test # 2
Test # 3
Test # 4
16.90 minutes/inch
10.37 minutes/inch
8.34 minutes/inch
14.46 minutes/inch
All of these test results are acceptable for the construction of leach field systems for
onsite sewage treatment and disposal systems. Individual percolation tests must be
accomplished for each specific leach field site prior to construction.
6. P.U.D. Zoning Regulations
The current P.U.D. zoning regulations are attached in EXHIBIT A.
The modified plan anticipates changing the regulations to read as follows:
Section I.
A. To carry out the purposes and provisions of the Garfield County Zoning
Resolution, Garfield County, Colorado and, particularly, Section 1 .04 of that
title, as amended, the Westbank Ranch Planned Unit Development Zoning
District is further divided into the following Zone District classifications:
R/S.F. - Residential Single Family District
R/M.F.2 - Residential Duplex District
R/M.F.4 - Residential Multi -Family, fourplex District
O.S. - Open Space

16. Engineering Geology
A reconnaissance geologic investigation of the property has been conducted by
CTL/Thompson, Inc., and is included as a part of this submittal as EXHIBIT G.
17. Drainage
The road system serving the development will cross a number of minor drainages.
Drainage structures for these crossings have been designed on the basis of analysis
of the drainage basins which they serve for a 100 year frequency storm event. The
hydraulic calculations determining the 100 year frequency storm events in the
drainage basins effecting this property are illustrated in EXHIBIT H, DRAINAGE
ANALYSIS.
18. Wildlife
The Division of Wildlife mapping places this development in elk winter range and
critical deer habitat. It is understood that some impact on the big game herds will
result from this development. The following conditions are proposed as additions to
the protective covenants of the development to mitigate some of the impact.

19. Wildfire Hazard
The area of this development, which is in excess of 30% slope and in the densely
vegetated drainages, has been identified as medium to high hazard for wildfire, in a
letter from Mr. Kelly Rogers of the Colorado State Forest Service. The site was also
visited by representatives of the Carbondale & Rural Fire Protection District. As a
result of this visit, a letter was written by Mr. Ron Leach, Chief of that district and a
Memorandum was written by Mr. James Mason, Director of Glenwood Emergency
Services. Recommendations were made regarding the development in all three of these
communications. As a result of these recommendations, the following conditions are
proposed as additions to the protective covenants of the development to mitigate this
potential hazard:
A. Structures shall not be constructed in or at the head of topographic drainage
features.
B. All vegetation except low ground cover such as mowed grass shall be
removed for an area 10 feet on all sides of all structures.
C. Brush and trees within 30 feet of all structures shall be thinned, if necessary,
so that the remaining clumps are no more than 10 feet wide.
D. Structure roof coverings shall be of non-combustible materials.
Additionally, the design criteria proposed by Mr. Leach and Mr. Mason is incorporated
in the road and utility design.
Copies of the letters from Mr. Rogers, Mr. Leach and Mr. Mason are included as

RE: Riverbend Subdivision
Site Application
Dear Mark:

CAN -AFIELD COUNTY

The purpose of this letter is to verify my request for an agenda position on the August
Planning & Zoning Commission meeting for consideration of a Site Application for the
River bend Subdivision. The Site Application itself will be delivered to your office this
Friday, July 30, 1993.
For the benefit of the Planning & Zoning Commission members, the Colorado Department of
Health (CDOH) requires that any modification or upgrading of a wastewater treatment facility
would require a Site Application. The Site Application in turn requires a review and sign -
off from the Planning & Zoning Commission as well as the Environmental Health Officer for
the County of jurisdiction.
Briefly, the Riverbend Subdivision is currently served by a two cell wastewater pond
system that was constructed prior to any formal standards instituted for this type of
wastewater treatment facility. The facility currently is non -conforming with the current
design standards and is not providing adequate service to the residents of the Riverbend
Subdivision. It is the intent to bring the wastewater treatment facility into compliance by
upgrading the existing facility and adding irrigation equipment to the existing cells,
construction of a settling cell, providing the disinfection of the effluent and finally
providing for effluent disposal either through direct discharge to the Colorado River or
through subsurface disposal.
Subsequent to receiving a Site Application approval through CDCH, the facility then will be
subject to a Discharge Permit Application, Garfield County being a review agency for that
permit as well.
Both myself and Mr. Steve Boat, representative for Riverbend Subdivision, will be in
attendance at the August Planning & Zoning Commission hearing to present the Site
Application to the Commission and also to answer any questions that the Commission
members may have.
Thank you for allowing us to be on the August agenda. I trust that the above is sufficient
to summarize our submittal to you prior to its receipt on Friday.
Respectfully submitted,
