4. Col-orado Division of Water Resources had expressed concernsabout Lhe fact that their comments from the Sketch plan hadnot been addressed. Specifically, they were concerned thatthe Park Ditch water may not be available for augmentationand that the location of the main well- is not within 2OO ft.of the proposed location in the augmentation plan which willrequire a change in the augmentation p1an. There is no welllocation within 200 ft. of Lot I , which will have anindividual well on it al-so. That the water augmentationplan should be turned over to the Homeownerrs Associationfor management of, and ownership of, the water rights. A11of these comments resulted in a response to . the Divisionfrom the applicant's attorney. (See pages /f )These letters resulted in a recommendation-oE approval fromthe Division, provided the conditions noted in Mr.Leavenworthrs May 10, 1989 letter. (See pages/Jf-2L )

Staff Comments
The applicantrs engineer has noted that the iron content ofthe water is higher than the recommended Level of 0.3 mgrzl.Both the applicant's engineer and the state HealthDepartment engineer note that the high iron content willstain plumbing fixtures. The state Health Department notesthat high iron content may stain laundry too. The iron mayal-so present a slight detectable taste to persons notaccustomed to higher than normal iron content in the water.while this does not present a health threat to anyonedrinking or using the water, it is something potenLialpurchasers should be made aware of at the time of purchase.A plat note should be placed on the Final plat noting that'without individual treatment. in-house, the higher thanrecommended Level of iron in the water may cause staining ofplumbing fixture and laundry, as well as having detectabletaste. n

RE: PJ.nyon Peaks Subdivlslon, Garfield County
Dear Mark:
I have revLewed the prelinJ.nary plan for Plnyon Peaks Subdlvislon and have the
followLng comments:
1. The weLl system that w111 serve more the 15 lots w111 be consldered a
Public Water System by the Colorado Prlmary Drlnklng WaEer RigulatlonP i
therefore, the deslgn for coflectLon and treatment of the water musE be
subnltted for revLew prlor to constructlon.
2. The Lron concentratlon from the above well was above the 0.3 mg/l
secondary standard. Secondary standards are non-enforceable, but each
potentlal hone buyer should be warned that iron leve1s above 0.3 mg/l can
cause stalning of plunblng flxtures and laundry.
3. Indivldual sewage dlsposal systems must be handled at the County level
unless they reach a deslgn flow of 21000 gpd or greater.

RE: PiNYON PEAKS SUBDIVISION
Dear I'lr. Bean:
At your request and in accordance with S.B. 35 we have revierved the
materials for the proposed residential subdivision referenced above. From a
geotechnical standpoint the subdivision is entirely feasjb'le i.f certain
p..iiriioni retateh to slope stabi'lity, drainage, and sewage disposal ale
follorved. These are addressed in the accompanying Ljncoln DeVore report and
tfre ietter of March-lB, .l969, to Scott hlritbr trom t'ticholas Lampiris,
Consulting Geologist.
I ) Steeper parts of the project area are pote-ntia'l1y unstable and
shoufa Ub avoided as buiiOtng sites. Sufficient setbacks should
be made foi utiilty tines ant where possib'le, roads, to minimize
the possibi'lity of excessive maintenance costs and occasional
loss of service.
2) Because of the variable bedrock and soil conditions across the
p.oject area,-it will be absolutely critical for individual soils
and foundation investigations to be conducted for each building-
site. Simijiity Uiainige plans should consider the locations of
buildings and roads and on overall integrated drainage plan
shoulO 5e Oevised that will seek to minimize erosion and related
damages.
3) Percolation tests indicate that some lots wil'l most likely have
conditions where engineered septic systems wi'11 be necessary f91
proper leach-fie1d [erformance. PotLntia] 'lot purchasers should
be advised of this by appropriate plat notes.

Dear Mr. Bean:
1,1e have received additional information concern'ing the above referenced
prel i mi nary p'l an from Lee Leavenworth, I e$al counci J foI the - project
froponents . Ihcl uded was a I i st of the augmentati on water from Case No.
7gCWg7 committed to other developments and a copy of the shares of the Park
Ditch owned by the Carbondale Land Dbvelopment Corporation. Mr. Leavenworth
also states -that the wells to be constructed for this development will be
w'ithin 200 feet of their decreed locat'ions.
This information addresses the concerns we expressed jn our last
letter to the county dated May 2, 1989. As long as the condjtions djscussedjn Mr. Leavenworth's lLtter to the county are complied with, we have no
further objections to this proposal. We would point out, however, that the
consumptive use analysis by Mr.'Zaircanella did not include water for livestock
as pei^ Case No. 79-Ct^197. It appears that adequate water wil'l be available for
the l'ivestock allowed by the decree.

Re: Pinon Peaks Subdivj.s!on/nt CorPoraLion
Dear Mark:
I am writing on behalf of the Carbondale Land Development
Corporat,ion. I am writing to respond to the letter from the
Division of Water Resources dated May 2, 19S9, concerning the
proposed water supply for the Pinon Peaks Subdivision. First,,
It tfre outset, Iet me say that I concur in your recornmendation
thatr prior to final plat approval r do approved augmentation
plan be submitted along with the letter frorn the State Division
of Water Resources confirming that the augmentat,ion plan will
meet the water right needs of Ehe subdivision. We are confident
that our proposals to address the concerns of Ehe Division of
Water Resources wilt be satisfacLory and that they will approve
the proposed water supply plan.
Carbondale Land Development Corporation (Clrc) is the owner
of five shares of t.he Park Ditch and Reservoir Company as indi-
cated in the prior water augmentation plan decreed in Case No.
7gCWg7. A copy of the stock certificate is enclosed. The
Division also askeO for a breakdown of the augmentation front
Case No. 79CW97 that has previously been utilized in other
augmentation plans or conveyed to third parties. To date, a
total of under B.O acre-feet of the 42.44 acre-feet of excess
historic consumptive use determined in said case has been uti-
lized by third parties. A detailed breakdown of this amount
will be provided to the Division of Water Resources' I would
note, however, that the 42.44 acre-feet of excess historic con-
sumptive determined in Case No. 79CW97 is in addit'ion to the
5.5i acre-feet of consumptive use committed to the augmentation
plan decreed in Lhat case. Thereforer the augmentation for the
iinon peaks Subdivision remains viable and intact and unaffected
by prior commitments of excess augmentat,ion waEer. In addition,
CLoc will be conveying a sufficient amount of shares in the Park
Ditch to ensure [fraC the Park Ditch has adequate replacement'
water available for the subdivision, including Lots I and 17.

The Division of Water Resources is also correct' that the
exist,ing r"ii-i" not within 200 feet of the decreed location of
any of the ;ve1ls adjudicated in case No. 79CW96' CLrc intends
t,o dril1 a new well to be used to provide t'he -subdivision'swater supply uritfrin 200 feet of an exiiting decre-ed location and
will submit evidence of the location and irre yietd of this well
;;i;.-i; final plat: rl addition, Lots 1 and 17, which are pro-
ioseO to have iirOiviOuat wel1s, will, at the time of f inal platr
be served uv *.irs drilled within 200 feet of existing decreed
weIIs. To the extent the decreed l0cat'ions are not l0cated on
in" Iot, tinif plat will provide for easements for Lhe drilling
of a well within 200 feet of the decreed location and easements
f or a water line to the property boundary. Therefore, all wells
will be drilled within ZOO-f""i of thei; decreed locations, and
; change of water right application will not be required.
The Division is also correct that the existing augment,at'ion
plan does not provide for augmentation during the winter
(November I through April 30). However, no winter calls have
occurred to date and, as indicated in t,he attached Ietter from
wright water Engineers, are not expected to occur in Ehe fore-
seeable future. Howeverr to ensure that sufficient water rights
are available in the future to provide winter augmentat'ion in
the event it, is needed, cLDC will convey to Ehe Homeowners
Association a total 0f 5.51 acre-feet of COnSUmptive use asso-
ciated with the Park Ditch shares. As you can s9e from wright
water Engineers' letter, this quantity_ of- water., because of the
reduction in the number of Io[s involved in the propo-sed =y?-
division from that contemplated in Case No. TggtlgT I will provide
; sufficient amount of augmentation water to cover any augmen-
tation needs dur ing th; winter period. The Homeowners
essociation document,J will clearly indicate that, in the event
winter augmentation is required, if,e HomeownerS Association will
be required to pursue any water court apPlica-tions needed for
this purpose. However, because augment'alion during lhu winter
p"ii"d i= not likely to occur in the foreseeable futurer we
believe it is premature to pursue or require the applicant t'o
pursue such an lpplication at this t'ime '
Finally, I would reiterate my opinion that' t'he total amount
of lawn irrigation provided for the 69 units can be reallocat'ed
to the 19 units without further water court approval, since the
location of the land to be irrigated has not changed '

Re: Pinyon Peaks Development
Dear Mr. Writer:
At your reguest we have revie'nred the augmentation plans for the Pinyon
Peaks subdivision (previously the Carbondale Land Development Companysubdivision). water court case No. 79C,ir91 provided a "legal" water supplyfor 72 single family units with 3.5 persons per lot, with each personutilizing 90 gallons of water per day. The augrmentation plan presented in
79Ovf97 also provided for two horses per lot for 39 Iots. The total con-
sumption of water for the originally proposed development ( including three
additional lots) as provided in the augmentation plan vras 5.51 acre-feet of
consumptive use.
It is our understanding that the new configuration of the development will
have only 19 lots and will use less water than the original plan. Since
less water will be used the 79C,r91 decree will stil1 cover the "legal"water reguirements for the development. We assume that each lot will have
a year around occupancy rate of 3.5 people reguiring 90 gallons per capita
per day. each lot in the proposed subdivision would have a total of 3600
sguare feet of irrigated lawn and garden or a total of 1.57 acres of irri-
gated land. Table 1 presents Lhe water reguirements for the currently
plarmed Pinyon Peaks subdivision.
The total future consumpti.ve use of the Pinyon Peaks subdivision will be
3.89 acre-feet. This is less than the original 5.5L acre-feet provided forin the oriqinal decree. It is our opinion that the proposed new future
uses can be adeguately provided for in the augrmentation plan, Case No.
799i197.
It is our opinion that there will be no non-irrigation season call on thejunior well rights r:nti1 such time as oil shale or other major indusErial
use on the rvestern slope are developed. Thus no winter augmentation is
needed in the near future. However v!,e recorTmend that Pinyon Peaks plan on
providing winter augrmentation water in the future. This can be done by
assigning 1.00 acre-feet of lhe 199f97 consumptive use to the homeowners(that portion not reguired for direct summertime augmentation). In turn
the homeowner would agree, when reguired, to build a 1.5 acre-foot pond and
operate it as an augrmentation reservoir to meet senior downstream calls.
