Re: TCI Lane Ranch PUD/Preliminary Plan

W. Division 5, W. District 38
Dear Mr. Hall:
We have reviewed the above -referenced proposal to subdivide a parcel of 100.52 acres to
contain a total of 89 single-family dwellings. The Mid Valley Metropolitan District (the District) is to
provide the domestic water supply and wastewater disposal. The District provided a conditional
letter of commitment dated February 14, 2007. Irrigation water will continue to be supplied by
decreed surface water rights. No water use estimates were provided.
The District currently uses five existing permitted, decreed wells, in conjunction with a
decreed plan for augmentation and a contract for 300 acre-feet of Ruedi Reservoir water, to
supply developments within its boundaries. Existing annual diversions by the District of 773.3
acre-feet provide potable water for 1578.2 EQRs. The total production capacity of the wells is
1345 gallons per minute during the irrigation season (May through September), and 975 gallons
per minute during October through April due to the fact that Well Nos. 3 and 4 appear to be
hydraulically connected to the Robinson Ditch. Note that there are plans to line the Robinson
Ditch in the near future and this may negatively affect production from those wells. The District
anticipates that when build -out within its boundaries is reached, a total of 2760 EQRs will be
served, and additional future development in areas currently outside District boundaries will
increase the demand to 4267 EQRs, which is equivalent to 1673 acre-feet per year. Since the
well permits allow the withdrawal of up to 2294 acre-feet per year, and the District has additional
decreed sources of supply available, it appears the District has an adequate legal water supply.
While the MVMD Water Rights Analysis by Schmueser Gordon Meyer (dated February 13,
2009) concludes that the District has an ample supply based on annual and monthly demand
estimates, the MVMD Water System Master Plan by Schmueser Gordon Meyer states that the
firm capacity of the wells is not adequate to meet the maximum daily demand of 2330 gallons per
minute. Additionally, the reports provided do not include any information on the anticipated yield
of any of the wells. As a result, we are unable to verify the District's water supply is physically
adequate. The District should demonstrate that it has sufficient water resources to meet its
commitments in terms of an overall annual water supply and daily availability.
The submittal indicates that existing ditch water rights will be used on historically
irrigated lands, as well as for irrigation of individual lots and for water features and wetlands
creation. The use of the irrigation water rights must not result in an expansion of use, and a

change of water rights application may be necessary to allow for irrigation of lands that were not
historically irrigated, including wetlands, as well as for use in water features (e.g. the proposed
"naturalistic stream course" for the Blue Creek Ditch).
The submittal also indicates that up to one acre of wetlands may be created to
compensate for disturbances to 0.5 acres of existing wetlands. The creation of the wetlands will
cause depletions to the stream system through evaporation from the water surface and the
consumptive use of water by plant life. The Roaring Fork River is in an overappropriated stream
system, therefore, to prevent injury to vested water rights, wetlands mitigation must be limited to a
one-to-one ratio. If the mitigation exceeds this ratio, the stream system must be compensated for
these depletions in time, place and amount through a court approved augmentation plan or a
State Engineer approved substitute supply plan. The creation of the wetlands may also expose
ground water, which by Colorado State Statute is considered a well, and must be permitted by this
office prior to construction.
Our records also indicate that several exempt wells, including the Oscar Cerise Well
Nos. 1 through 4, may currently exist within the proposed development. Note that Section 37-
92-602(3)(b)(III), CRS, requires that the cumulative effect of all wells in a subdivision be
considered when evaluating material injury to decreed water rights. Therefore, the existing
exempt wells must be included in an augmentation plan, or must be plugged and abandoned
since the provisions of CRS 37-92-602 which allowed for issuance of the well permits will no
longer apply.
Therefore, pursuant to CRS 30-28-136(1)(h)(II), it is our opinion that the proposed water
supply will not cause injury to existing water rights so long as the District operates according to
the terms and conditions of its current plan for augmentation. However, due to a lack of
information we are unable to comment on the physical adequacy of the water supply. Note that
use of the irrigation water rights must not result in an expansion of use, and approval of a change
of water right application by the water court may be necessary if the place or type of use is
changed. Please contact me if you or the applicant has any questions concerning this matter.

RE: TCI Lane Ranch Development preliminary plan review.
Dear Scott:

kph OF
For Wildlife -
For People
The proposed TCI Lane Ranch property located between Hwy 82 and the Roaring Fork River
east of Blue Creek Ranch does not lay within any mapped critical wildlife areas, but is adjacent
to important elk and deer winter range on the south side of the Roaring Fork River. Use by
deer and elk on the property generally occurs during the winter and spring months but with
some year round deer use on the riparian corridors along the Roaring Fork River and Blue
Creek. Elk use and game damage problems have increased in the last couple of years on the
property with elk being drawn to hay being stored on the property. In addition the property is
home to many small mammals, neo -tropical song birds, raptors, wild turkeys and amphibians.
The Division is pleased with many of the elements of the proposed development. The
conservation easements to be held by the Roaring Fork Conservancy will go far to help protect
the riparian and wetland habitats along the Roaring Fork River and Blue Creek. The DOW is
also very supportive of the developments plan to allow public fisherman access to the Roaring
Fork River.
The proposed development will have some direct and indirect impacts on wildlife. Until a final
site plan is implemented not all impacts to wildlife can be addressed, but the Division would
like to make the following recommendations to help minimize potential impacts:
1. Building envelopes for lots 60-64 should be pulled as far north as possible to eliminate
any removal of riparian vegetation. Maximize building in the pasture areas that have
previously been disturbed.
2. The riparian areas along the Roaring Fork River and Blue Creek are extremely
important to wildlife. Due to the critical nature of these areas for wildlife it is
recommended that any proposed trails/paths be minimized and public access should be
limited into these areas. Access should be closed completely Dec 1- March 15 to limit
disturbance to big game and wintering bald eagles utilizing the riparian corridor.
DEPARTMENT OF NATURAL RESOURCES, Harris D. Sherman, Executive Director
WILDLIFE COMMISSION. Robert Bray. Chair • Brad Coors. vice Chair. Tim Glenn. Secretary
3. As noted the property in not located within any mapped big game critical habitat areas,
however elk usage of the property has increased considerably during the winter months.
Deer and elk conflicts are to be expected in the development and plantings of native
vegetation are encouraged to help reduce some of those conflicts. Eliminating plantings
of any bent', fruit, or nut producing plants or shrubs will help discourage elk, deer, bears
and other wildlife from feeding on landscaping. Homeowners need to be aware that the
Division of Wildlife is not liable for any damage to landscaping by deer, elk, or bear.
4. The proposed bridge over the Roaring Fork River should be gated to prohibit access to
the RFTA during the winter closure period.
5. Bear/human conflicts have increased in the Roaring Fork Valley and in the vicinity of
Blue Creek Ranch and Catherine Store, and have the potential to be a reoccurring
problem. It is important that certain measures be taken to minimize these conflicts:
a. Homeowners have and use an approved bear -proof container for storing all
trash/garbage.
b. Pets should be fed indoors, and pet food or food containers should not be left
outside;
c. BBQs should also be securely housed in the garage or cleaned with a bleach
solution when not in use due to the fact that leftover food and grease are an
overwhelming bear attractant;
d. Round door knobs on the outside of doors rather than lever -type can limit bear
access into houses.
6. All utilities buried.
7. Fencing should be held to a minimum. Any necessary fencing should be wildlife
friendly. For wire fencing, 42" maximum height, 4 wire with a 12" kick space between
the top two strands. Rail fencing should be 48" or less with at least 18" between 2 of
the rails.
8. Homeowners are responsible for removing dead wildlife which may die on their
property.
9. Follow recommendations outlined in the wildlife report prepared by Eric Petterson of
Rocky Mountain Ecological Services, Inc.

File Number SPP16909, Garfield County, CO: CGS Unique No. GA -09-0004
Dear Mr. Hall:
Colorado Geological Survey has completed its site visit and review of the above -referenced project. I
understand the applicant proposes to plat 89 residential units on a 100.5 -acre parcel located between the
Roaring Fork River and Highway 82, southeast of Catherine Store.
With this referral, I received a Preliminary Plan/PUD Application, including a Preliminary Geotechnical
Study (HP Geotech, March 14, 2008), a Final Drainage Report (Drexel, Barrell & Co., September 12,
2008), a set of two Preliminary Plat drawings (Drexel, Barrell & Co., December 24, 2008), and a
Radiation Survey (Yeh and Associates, February 27, 2007). CGS visited the site on January 16, 2009.
The site was covered with snow at the time of our visit.
HP Geotech's geotechnical report provides a very good description of regional and site geology. I agree
that flooding and sinkholes are the primary concerns on this property. HP provides appropriate general
recommendations regarding mitigation of sinkhole hazards (pages 5-6) and preliminary foundation,
subsurface drainage, below -grade construction, floor system, and surface drainage design
recommendations (pages 8-10). These recommendations should be strictly adhered to.
Roarinb Fork River flood -related hazards. The Final Drainage Report states (page 2): "...portions of
the property are within the 100 -year floodplain. Several home sites on the southern portion of the site are
located within the existing 100 -year floodplain. These sites will be elevated to a minimum of 1 -foot
above the 100 -year base flood elevation. Designated finish floor elevations in this area are a minimum of
1.5 -feet above the 100 -year base flood elevation."
Flooding is a hazard that must be addressed beyond raising building pads one foot above the 100 -year
base flood elevation, not only to reduce risks associated with rising waters but also to reduce the risk of
undermining due to stream channel erosion and undercutting. Slope armoring such as riprap should be
placed on the face of all constructed slopes used to raise building pads and roads above the flood zone.
The need for and feasibility of additional channel and bank stabilization, scour mitigation, and energy
dissipating measures should be evaluated.
Sinkholes. Sinkholes are a potential concern on this site, but are of far less critical concern than flooding
and flood -related erosion hazards. HP's recommendations on pages 5 and 6 are appropriate: "If
conditions indicative of sinkhole related problems are encountered during site specific soil and foundation
studies for the houses and other movement -sensitive facilities an alternative building site should be

considered or the feasibility of mitigation evaluated... Prospective homeowners should be advised of the
sinkhole potential, since early detection of building distress and timely remedial actions are important in
reducing the cost of building repair should an undetected subsurface void start to develop into a sinkhole
after construction."
Thank you for the opportunity to review and comment on this project. If you have questions, need
clarification of issues identified during this review, or require additional review, please call me at (303)

RE: TCI Ranch Planned Unit Development
Dear Commission Members:
RECEIVFn
FEB 0 9 2009
GARFIELD COUNTY
BUILDING & PLANNING
At its January 29, 2009 meeting, the Carbondale Planning Commission reviewed the referral for
the Planned Unit Development Application for TCI Ranch. The Planning Commission
requested that their comments be forwarded on to Garfield County.
The property is located between Blue Creek Subdivision and the Waldorf School and is south of
Hwy. 82. The proposal is to rezone the property from A/RR/D to a PUD and subdivide 100.52
acres into 89 lots with 68 of those acres remaining in open space. While, the property is
currently zoned A/RR/D which only allows one unit per two acres, the County approved a
Comprehensive Plan Amendment in July of 2007. The amendment changed the land use
designation from Residential Low Density to Residential High Density.
There are a number of recommendations in the TCI Lane Wildlife and Vegetation Assessment
Report that are intended to protect the wildlife that currently exists on the property. Some of the
impact mitigation recommendations include discouraging fencing which is not designed to allow
wildlife passage, limiting the number of domestic animals, planting of vegetation along
roadways to avoid spotlighting of foraging game at night, etc. The Carbondale Planning
Commission would strongly suggest that all of the recommendations in the report be accepted
and incorporated into the subdivision documents. While these recommendations should be
included in the Declaration documents, they should also be incorporated into the PUD plan so
they cannot be changed by a vote of an association of property owners.
Ute Ladies' -tresses, an orchid which is listed on the Endangered Species list, is found on this
property. The TCI Lane Wildlife and Vegetation Assessment Report sets out a number of
recommence M nagement practices to control weeds, as well as suggested management
(170) 96 3-273 3 Fax: (970) 963-91 l0
practices to assure that the orchid population remains stable on the property. The Planning
Commission would like to recommend that these management practices be incorporated in the
Declarations, as well as in the PUD plan.
The Planning Commission had concerns about the ability of the Hwy. 82 and County Road 100
intersection to absorb the additional traffic. They are concerned that there could be potential
stacking of vehicles on the frontage road. The Planning Commission is aware of the number of
bicyclists that use the frontage road. The Commission is concerned about conflicts between
bicyclists and vehicles on the frontage road and asked that issue be addressed.
The Traffic Impact Study included with the application notes that the northbound approach of the
Hwy. 82/County Road 100 intersection currently appears to be operating unacceptably during the
morning peak hour, given there is a single lane for all three potential northbound movements.
The northbound right turning movement currently accounts for 75% of vehicles using this
approach during the morning peak hour. The County should consider that a condition of
approval be that a dedicated right turn lane be constructed to allow cars coming off of County
Road 100 to turn right onto Hwy 82 towards Aspen.
The Planning Commission noted the proximity of the development to the Roaring Fork River.
They suggest that there be no construction within the 100 year floodplain due to potential
impacts downstream. Firefly Loop raises particular concern because of its location near the river
and the floodplain. The Planning Commission asked if it would be possible to cluster the
development on Firefly Loop to lessen the impacts on the river and floodplain.
The Commission discussed the impacts on the pedestrian bridge to the Roaring Fork River and
asked that those impacts be assessed. The Commission assumes that the Army Corp of
Engineers will be consulted prior to any construction.
The Planning Commission asked that the Roaring Fork Valley Planning Commission be
consulted as part of the land use process for the TCI Lane Planned Unit Development.
The Planning Commission appreciated the pedestrian and bicycle connections and suggested that
the County be sure that those concepts remain intact through the process. The Commission also
appreciates the Open Space concept and asks that the concept also remain in place. The
Commission commended the development as far as the net zero energy plan.
On broader discussion regarding development on the valley floor, the Planning Commission
would like to suggest that any future changes to the Comprehensive Plan be done in
consideration of the entire area rather than on a piece -mail basis. When the Garfield County
Comprehensive Plan was developed, the citizens of Carbondale and Town Staff were involved in
the process. This planning document was intended to guide growth and development in the rural
areas around Carbondale.
The Planning Commission is concerned with changing the zoning density without major
attention to issues of access and safety. Also, once infrastructure is extended to this
development, it may set a precedent for the nearby agricultural land to develop.
Thank you for allowing the Town of Carbondale the opportunity to comment on this proposal.
Please let me know if you have any questions.

Dear Mr. Hall:

FEB 0 9 2009
GARFIELD COUNTY
BUILDING & PLANNING
The residents at Aspen Equestrian Estates are concerned about the additional traffic
impacts the TCI Lane Ranch subdivision will have on the intersection of Catherine Store
Road and HWY 82.
The TCI Lane Ranch is proposing to add an addition 98 homes to a 100 -acre site. The
proposed site is located between Blue Creek subdivision and the Waldorf School. The
Catherine Store Road would be the nearest access to HWY 82. The Institute of
Transportation Engineers Trip Generation Guideline estimates that each single family
home will generate 9.57 vehicle trips per day. With the addition of 98 homes in the TCI
subdivision, there would be an additional 938 vehicles a day using this intersection - most
of these trips will be during the peak hours.
To accommodate the additional traffic at the Catherine Store Road intersection, a
dedicated right turn lane needs to be constructed on the south side of HWY 82 to
facilitate right turns up -valley. As it is now, a vehicle waiting to turn left will block the
right turn movement. Some drivers have begun using the dirt shoulder to facilitate the
right turn. This is not a safe practice.
We asked that Garfield County place a Condition of Approval on the developer to widen
the paved area of the Catherine Store Road and establish a dedicated right turn lane.
There should also be enough room to allow for stacking of vehicles waiting to execute
the right turn up -valley.

Dear Fred:
We have reviewed additional information regarding the above -referenced proposal to
subdivide a parcel of 100.52 acres to contain a total of 89 single-family dwellings. The Mid Valley
Metropolitan District (the District) is to provide the domestic water supply and wastewater disposal.
The District provided a conditional letter of commitment dated February 14, 2007. Irrigation water
will continue to be supplied by decreed surface water rights. No water use estimates were
provided.
The District currently uses five existing permitted, decreed wells, in conjunction with a
decreed plan for augmentation and a contract for 300 acre-feet of Ruedi Reservoir water, to
supply developments within its boundaries. Existing annual diversions by the District of 773.3
acre-feet provide potable water for 1578.2 EQRs. The total production capacity of the wells is
1345 gallons per minute during the irrigation season (May through September), and 975 gallons
per minute during October through April. The District anticipates that when build -out within its
boundaries is reached, a total of 2760 EQRs will be served, and additional future development in
areas currently outside District boundaries will increase the demand to 4267 EQRs, which is
equivalent to 1673 acre-feet per year. Since the well permits allow the withdrawal of up to 2294
acre-teet per year, and the District has additional decreed sources of supply available, it appears
the District has an adequate legal water supply.
While the MVMD Water Rights Analysis by Schmueser Gordon Meyer (dated February 13,
2009) concludes that the District has an ample supply based on annual and monthly demand
estimates, the MVMD Water System Master Plan by Schmueser Gordon Meyer states that the
firm capacity of the wells is not adequate to meet the maximum daily demand of 2330 gallons per
minute. The District also holds conditional underground water rights for seven additional wells,
each decreed for 500 gallons per minute. The decreed locations appear to be located in or near
the alluvium of the Roaring Fork River. If the proposed wells produce at rates similar to the wells
that are currently in use by the District, and with sufficient storage capacity, the water supply
should be physically adequate.
The submittal indicates that existing ditch water rights will be used on historically
irrigated lands, as well as for irrigation of individual lots and for water features and wetlands
creation. The use of the irrigation water rights must not result in an expansion of use, and a

change of water rights application may be necessary to allow for irrigation of lands that were not
historically irrigated, including wetlands, as well as for use in water features (e.g. the proposed
"naturalistic stream course" for the Blue Creek Ditch).
The submittal also indicates that up to one acre of wetlands may be created to
compensate for disturbances to 0.5 acres of existing wetlands. The creation of the wetlands will
cause depletions to the stream system through evaporation from the water surface and the
consumptive use of water by plant life. The Roaring Fork River is in an overappropriated stream
system, therefore, to prevent injury to vested water rights, wetlands mitigation must be limited to a
one-to-one ratio. If the mitigation exceeds this ratio, the stream system must be compensated for
these depletions in time, place and amount through a court approved augmentation plan or a
State Engineer approved substitute supply plan. The creation of the wetlands may also expose
ground water, which by Colorado State Statute is considered a well, and must be permitted by this
office prior to construction.
Our records indicate that several exempt wells, including the Oscar Cerise Well Nos. 1
through 4, may currently exist within the proposed development. Note that Section 37-92-
602(3)(b)(III), CRS, requires that the cumulative effect of all wells in a subdivision be
considered when evaluating material injury to decreed water rights. The Oscar Cerise Well Nos.
1 through 4 were granted absolute water rights in W-890 on January 5, 1973, and may be
considered beneficiaries of the Green Mountain Reservoir Historic Users' Pool for a mainstem call
on the Colorado River. However, these wells could be subject to administration in the event of a
local call on the Roaring Fork River.
Therefore, pursuant to CRS 30-28-136(1)(h)(II), it is our opinion that the proposed water
supply is physically adequate and will not cause injury to existing water rights so long as the
District operates according to the terms and conditions of its current plan for augmentation.
Note that use of the irrigation water rights must not result in an expansion of use, and approval of
a change of water right application by the water court may be necessary if the place or type of use
is changed. Please contact me if you or the applicant has any questions concerning this matter.

RE: Garfield County Road 100/ SH 82 Intersection
Dan,
Thank you for your referral comments dated January 23, 2009 regarding the TCI Lane Ranch
Preliminary Plan/ PUD in Garfield County. I would like to take the opportunity to open the
discussion on a topic that you brought forth in your letter regarding the current and future
operation of the CR 100/ SH 82 intersection, as TCI Lane Ranch is an interested stakeholder and
potential future user of this intersection.
As you know, the northbound approach to this intersection has been achieving substandard
performance for some time, as CR 100 is frequently used as an alternative route to and from the
Town of Carbondale. To further challenge this situation, CR 100 was likely never designed for the
traffic volumes that it currently experiences. The Level 2 Traffic Impact Study for TCI Lane Ranch,
prepared by Drexel, Barrell & Co., identifies that the northbound approach currently operates at
LOS E during the morning peak hour and LOS D during the evening peak hour. The traffic counts
were performed here on May 29, 2008. The current intersection configuration provides one lane
for all NBL, NBT, and NBR movements. There is, however, an existing acceleration lane for the
NBR movement onto SH 82.
In your letter, you acknowledge the need for a dedicated northbound right turn lane, with or
without the projected traffic from TCI Lane Ranch. On this topic, the Traffic Study states: "A
northbound right turn lane would alleviate problems with the morning peak hour, under both
Year 2009 background and total conditions. The northbound right movement already has an
acceleration lane on State Highway 82, and if properly designed, could provide free movement
conditions for turning vehicles."
Your letter identifies that the future traffic generated by TCI Lane Ranch will account for less than
5% of the total volume of this intersection, and therefore an access permit is not required from
CDOT. With the understanding that TCI Lane Ranch will have some impact (although relatively
minor) to the traffic volume at this intersection, and that future residents of this project may
benefit from an improved intersection, we would like to express our interest in becoming a
partner in potential improvements.
Your letter further recommends that "Garfield County work with the users of the road to develop
a method in making these improvements recommended by the Study." You also suggest the
potential use of other funding sources to help make these improvements (DOLA, Hazard
Elimination Funding, and STIP Funding).
Given your recommendations and those of the Traffic Study, we have taken the initiative to
explore a potential northbound right turn lane configuration. This is included as an Exhibit
attached to this letter. We have voluntarily performed this feasibility analysis in order to provide a
starting point for discussions with potential stakeholders and users (i.e. Garfield County, CDOT,
Town of Carbondale, RFTA, TCI Lane Ranch, Blue Creek Ranch, St. Finnbar, Aspen Equestrian
Estates, Catherine Store, etc.), and to demonstrate the willingness of TCI Lane Ranch in becoming
a partner in potential intersection improvements upon project approval. One potential outcome
may be a cost-sharing agreement among appropriate stakeholders.
Please review the attached Exhibit at your convenience. We would appreciate the opportunity to
meet with CDOT, Garfield County and other stakeholders to discuss how to make these
improvements a reality.

I can help on this one. The nearest (geographically) Traffic Impact Fee Study Area is Area 11 which covers much of
Missouri Heights just across 82 from TO Lane. That fee would be about $384 per ADT. So, in this case, that would be
about $327,000. Scott can give you more detail.

Scott,
I have a question regarding the traffic impact concern to the County Road system:
If TCI Lane Ranch were in a designated Traffic Impact Zone per the County maps, what would be the calculated impact
fee for the project?
I think you see where I am going with this — I'm just trying to look at all alternatives right now in an effort to analyze all of
the equitable solutions. Knowing all of our options will assist the ownership in making educated decisions.

Subject: TCI Lane Ranch PUD Review
Scott — Thank you for the opportunity to review the TCI Lane Ranch PUD on near SH 82 and east of
County Road 100 (Catherine Store). CDOT has already issued an access permits for simple
connections on the Frontage Road system without highway improvements indicating conceptual
improvement. The applicant has not submitted a Notice to Proceed (construction plans) for the
access permits. The traffic study (Drexel, Barrell & Company, dated June 27, 2008) doesn't show
any frontage road improvements at the access points.
However, the study recommends intersection improvements at SH 82/County Road 100. The study
recommends additional northbound right turn lane on CR 100 and an additional northbound left turn
lane on CR 100 (double left) in the future. The study states the northbound right turn lane is needed
without project traffic. CDOT does not have any mechanism to require improvements when there is a
off-site existing improvement needed on a County Road. I would recommend Gar field County work
with the users of the road to develop a method in making these improvements recommended by the
study. I also recommend any other funding source that is available (DOLA, Hazard Elimination
Funding, and STIP Funding).
The Access Code states an access permit is needed when the traffic volume is over 20%. CR 100
traffic volume is 835 DHV. This development will only increase the traffic volume by less than 5%.
Therefore an access permit is not needed at the CR connection for this project. CDOT does not have
any process to make the developer address this need. The County through the land -use process
does have the ability to address this impact to the majority of the road users in the area.
This is a tough issue and CDOT is willing to sit down at the table and talk on ways to improve the
operation of the CR 100.
If you have any additional questions, please let me know.

RE: State Highway 82 / County Road 100
Intersection Capacity Improvement Memorandum
Garfield County, Colorado
Introduction:
This memorandum outlines the proposed effect of anticipated improvements to the intersection
of State Highway 82 and County Road 100 within Garfield County. The primary improvement
anticipated at this time is the construction of a right turn lane from northbound County Road
100 to the up valley direction of State Highway 82.
Project Background:
A traffic study was submitted to the Colorado Department of Transportation (CDOT) and
Garfield County by Drexel, Barrell & Co. - June 27, 2008 - regarding the projected impacts of
the TCI Lane Ranch residential development to be located along the SH 82 Frontage Road.
This development is approximately one quarter mile to the east of the intersection of County
Road 100 and State Highway 82. CDOT granted two access permits for this development to
the SH 82 Frontage Road (No. 308134 and 308135) on August 26, 2008.
As part of the study, the northbound approach of the County Road 100 / SH 82 was identified
as operating unacceptably under existing conditions. There is a strong imbalance in traffic flow
at the approach during the AM peak hour, with 74% of total approach traffic turning right onto
SH 82. As this approach is single lane, the right turning vehicles are forced to queue with the
through and left turning vehicles. This also results in the unpaved shoulder of County Road 100
being used as a right turn lane. A right turn acceleration lane on SH 82 is already in existence
at this location. The existing conditions at this location can also been in Figure 1.-

.„"sem.._ ta"`m.»............
Figure 1 - Existing Roadway Geometry
As can be seen in Figure 1, there are existing constraints to further expansion at this location.
The close proximity of the Catherine Store to County Road 100 currently limits widening to the
west. The existing Roaring Fork Transportation Authority park and ride facility provides some
barrier to the east.
While TCI Lane Ranch is expected to use this intersection as its primary access to SH 82, the
anticipated 23 vehicles using the northbound approach during the AM peak hour would
constitute only a 6% increase over the projected Year 2009 background traffic.
Queuing Analysis:
Synchro Version 7 was used to estimate the queues generated for the northbound approach of
this intersection, with and without the addition of a northbound right turn lane. As there is an
existing dedicated right turn acceleration lane in the up valley direction of SH 82, the potential
right turn lane was modeled as a free movement. Modeling in this fashion assumes that no
substantial queue would be generated by this movement. Therefore, the primary focus of this
investigation is on the existing northbound left -through -right lane. Following construction of a
right turn lane, this lane would only serve the left and through movements. The results of this
analysis are tabulated in Table 1. The full Synchro queuing analysis reports are attached to
this memorandum.
123 N 7`h Street, Suite 300 Grand Junction, Colorado 81501 Tel 970 257 1350 Fax 970 257 1066
Table 1: Queueing Analysis
*As the potential northbound right turn lane would be considered
a free movement, no substantial queueing would be a)pected.
Two variables are illustrated in Table 1; the 50" percentile queue and the 95" percentile queue.
The 50th percentile queue is the projected average queue expected during the peak fifteen
minutes of the respective peak hour. The 95th percentile queue is typically taken as the longest
peak hour queue to be anticipated under normal operating conditions.
As can be seen in Table 1, the construction of a dedicated right turn lane is expected to have a
substantial positive effect on the length of the queue experienced for northbound left and
through vehicles, especially during the AM peak hour. With the turn lane, the projected Year
2030 queues, including TCI Lane Ranch traffic, would be expected to be substantially lower
than those experienced under existing conditions. The PM peak hour, while also improved by
the addition of a right turn lane, would not be expected to experience as dramatic of an
improvement. This is likely due to the somewhat more balanced turning movement distribution
experienced during the PM peak hour.
The unusual geometry of adjacent roadways may have an effect on the actual queues
experienced at this location. The north flowline of the intersection of County Road 100 and the
SH 82 Frontage Road is approximately 130 feet south of the SH 82 traffic signal. It is unlikely
that the right turn lane would be extended past this point unless the entire section of roadway is
reconstructed. When through -left queues exceed this distance, right turning vehicles are likely
to be forced to remain with the through traffic, further contributing to the queue at this location.

*As the potential northbound right turn lane would be considered
a free movement, no substantial queueing would be a)pected.
Two variables are illustrated in Table 1; the 50" percentile queue and the 95" percentile queue.
The 50th percentile queue is the projected average queue expected during the peak fifteen
minutes of the respective peak hour. The 95th percentile queue is typically taken as the longest
peak hour queue to be anticipated under normal operating conditions.
As can be seen in Table 1, the construction of a dedicated right turn lane is expected to have a
substantial positive effect on the length of the queue experienced for northbound left and
through vehicles, especially during the AM peak hour. With the turn lane, the projected Year
2030 queues, including TCI Lane Ranch traffic, would be expected to be substantially lower
than those experienced under existing conditions. The PM peak hour, while also improved by
the addition of a right turn lane, would not be expected to experience as dramatic of an
improvement. This is likely due to the somewhat more balanced turning movement distribution
experienced during the PM peak hour.
The unusual geometry of adjacent roadways may have an effect on the actual queues
experienced at this location. The north flowline of the intersection of County Road 100 and the
SH 82 Frontage Road is approximately 130 feet south of the SH 82 traffic signal. It is unlikely
that the right turn lane would be extended past this point unless the entire section of roadway is
reconstructed. When through -left queues exceed this distance, right turning vehicles are likely
to be forced to remain with the through traffic, further contributing to the queue at this location.

Level of Service:
Per the 2008 Traffic Study, the northbound approach of the County Road 100 / SH 82
intersection is currently operating at Highway Capacity Manual, 2000 Level of Service (LOS) F
conditions during the AM peak hour, indicating that the approach is experiencing a high level of
congestion. This is consistent with the queuing analysis provided. While some of the delay
experienced on this approach can be attributed to the long 180 second cycle length used at this
intersection, the lack of a right turn lane also affects delay at this intersection.
With the addition of a northbound right turn lane at this intersection, the approach would be
expected to improve to LOS C following the build out of TCI Lane Ranch during both the AM
and PM peak hours. It is anticipated that the Level of Service for this approach would then be
maintained at an acceptable LOS D during the AM peak hour through the long term planning
horizon of Year 2030.
The stronger influence of left and through traffic during the PM peak hour may further degrade
Level of Service on this approach to LOS E by Year 2030, regardless of whether TCI Lane
Ranch is constructed. However, given the long cycle length of this traffic signal, LOS E is not
atypical for minor street approaches. Given this, the queue length should be considered the
most important Measure of Effectiveness at this location.
Conclusion:
The construction of a northbound right turn lane is believed to provide increased capacity for
the northbound approach of the County Road 100 / SH 82 far in excess of the impacts
anticipated from the addition of TCI Lane Ranch traffic.
At part of this effort is also anticipated that a raised median between the northbound and
southbound directions will also be constructed on County Road 100. This separation of traffic
flow should also provide a safety benefit to the south approach of this intersection as part of the
construction effort.

matter.
