Executive Summary
This application is a formal request to the Planning and Environmenlal Commission for a preliminary plat,
to re-zone a portion of the Mountain Bell site, and to amend Vail's Land Use Plan.
The preliminary plat has been included to describe a piece of ground approximately 6.6 acres in size at the
south edge of tie Mountain Bell site along Vail's North Frontage Road. The preliminary plat documents
indicate ihe proposed boundary and access through the site. The roadway through the site is intended to be
a private drive meeting all Town of Vail standard. Utility easements have been shown to allow all required
utilities to serve the future proposed buildings.
Simultaneously, with our request for the preliminary pla! this is a request to re-zone the 6.6-acre parcel
from its existing zoning of NAPD and G to the H zone district. The re-zoning will allow affordable living
units to be designed foi the site and to address a significant need for the Town of Vail. It is also the intent
ofthis development to design an early childhood learning center for the community. The 2 existing
children's ceniers would be-consolidated into a single upgraded facility where improved services and
program s could be developed.
The final request of ttris submittal is for an amerdment to Vail's Land Use plan. Specifically, we are
requesting that the subject 6.6 acre parcel be revised from open space to residential use. We believe this
request iiappropriate as it is intended to address a very real need for housing the employees that work for
buiinesses in the community. It will also provide sigrificantly upgmded facilities for the early leaming
center for lhe community.
The application follows the submittal requirements of Chapter 3, Title | 3 of the Town of Vail Zoning
Regu lations for Major SuMivisions.
The submittal includes an environmental impact report, a preliminary geotechnical investigation of
anticipated subsurFace soil and glound water mnditions, a geologic hazards study addressing the hazard
zones of the site and m itigation techniques, a traffic impact analysis and a written drainage report for the
site.
Specific items requested in 13.3.3 (items A-M) have been addressed in this submittal. hdividual drawings
requested have been included. These are the topographic plan, concept site plan including proposed
grading, existing mnditions on adjacent property within 200', graphic representation of all areas of the site
with a 40% slope or greater, dre preliminary plat plan and the Alta survey. We also have included a
conceptual utility plan with letters of service fiom the appopriate utilities companies.
Collectively, these docum€nts clearly describe the existing and proposed conditions. Additional specifio
information will be put forth with the development plan submittal after approval of the re-zoning and land
use amendment are in place

I. INTRODUCTION
Odell Architects, PC retained Stewart Environmental Consultants Inc. to perform an
Environmental lmpact Assessment of the proposed Middle Creek Village development. The
property is located adjacent to the Mountain Bell facility, directly north across Interstate 70 from
Vail Village. The proposed project consists of multi-family housing constructed on a 6.5-acre
site owned by the Town of Vail. The purpose of the project is to provide affordable housing for
people currently employed in Vail, who are presently living in or near the community. 1ne
groject owner is coughlin and company, 140 East 19th Ave., Suite 700, Denver, cblorado
80203-1035.
The site location is depicted on Figures 1 through 3. Photographs of the site are provided as
Figure 4.
II. PURPOSE
Th9 PurPose of performing the Environmental lmpact Assessment is to achieve the following
objectives:
A. Availability of lnformation: To ensure that complete information on the environmental
gffects of the proposed project is available to the Town Council, the Planning and
Environmental Commission, and the general public.
B. Environmental Protection A Criterion: To ensure that long-term protection of the
environment is a guiding criterion in project planning, and that land use and development
decisions, both public and private, take into account the relative merits of possible
alternative actions.
C. Review and Evaluation Procedure: To provide procedures for local review and
evaluation of the environmental effects of proposed projects prior to granting of permits
or other authorizations for commencement of development.
D. Avoid Geologic Hazard Areas: To ensure that the buildings are not constructed ingeologic hazard areas, by way of illustration, flood plains, avalanche paths, rocKall
areas, where such hazard cannot practically be mitigated to the satisfaction of the
Planning and Environmental Commission and the Town Council.
E. Protect Water Quality: To ensure that the quality of surface water and ground water
within the Town of Vail will be protected from adverse impacts and/or degradation due to
construction activities. [ord. 37 (1980) 10: ord. 19 (197e M: ord. 8 (1973) 16.100]

III. PROJECT BACKGROUND AND DESCRIPTION
Site Concept
The initial conceptual design approach for Middle Creek Village housing is meant to reflect a
new model of multi family housing in mountain communities. The site parameters and
community context were the prime motivators for the layout of the buildings and parking;
however, the solution incorporates some planning principles of a more "urban" nature.
The buildings are arranged around a pedestrian oriented "street" which creates an axis running
east to west across the site. The "street" rises to the center of the project, following the
contours of the site. Entries into individual units as well as project amenities will occur along the
path, and it is envisioned to include both hardscape and landscape areas. The pedestrian
street will be an active place reminiscent of other village centers in the community.
Encouraging the use of alternate transportation, our team proposes to work with the Colorado
Department of Transportation and the Town of Vail to create a project specific transit stop, as
well as develop pedestrian and bicycle access from the site into town. These are accessible to
the residences along a central pedestrian spine that runs down the hill and through a two-story
opening in the center building, ending at the proposed transit stop. Given that a large segment
of the market for this project will be seasonal employees, our team believes the daily use of the
automobile can be minimal. Consequently, the relationship between the car and the building is
downplayed in our solution.
Separating vehicle parking from the buildings allows the project to create a pedestrian oriented"village" character and allows the buildings to be sited closer together, thus visually reinforcing
this image. This is similar to the exterior pedestrian spaces created by the architecture at areai
9u9! as Bridge Street in Vail Village and Lionshead Village. The siting of the parking areas
behind the buildings will also help shield views of the lots from the frontage road and from
across the valley.
The Early Learning Center has been sited to the far eastern edge of the site, but is easiry
accessible from the residences on the loop road. This configuration provides a nicely separated
site for the children's facility.
The overall site concept adheres closely to the existing contours of the site. The buildings rise
and-fall across the length of the site with the terrain, creating an undulating profile thatlurther
reinforces the "village" concept.
Buildins Goncept
Further reinforcing the "village" concept, the buildings are designed as three separate buildingtypes' All the buildings will be one unit deep, creating cross flow ventilation and economy of
construction. There are no enclosed walkways or stairtowers, as the site allows the majority of
units to be accessed at grade. Intemal floor plans will develop stacked plumbing cores, and-the
mix of units will be designed to minimize structural offsets and maximize construction simplicity.
Each of the six residential buildings includes a one-story element on the end which houses
laundry and storage facilities for that building. The building orientation creates maximum

southern exposure for every unit. The fact that the buildings are simply one unit deepcreates
excellent opportunities for flow-through ventilation. Our proposal will incorporate highly efficient
mechanical and electrical designs. We believe on a scale of zero to five our development will
achieve a five, or the highest efficiency rating available. Since all units are accessed from grade
or a small stair, there are no interior corridors to heat or cool, further enhancing overall energyefficiency. Please refer to our preliminary LEED evaluation in Section Vt-..1 for additionil
information on energy and sustainability.
The overall character of the building design is meant to reinforce the "village" concept, with
varying building types, massing, and styles creating a cohesive whole. Stylistically, we will
incorporate the tradition of Vail Valley architecture while maintaining an economicit Oesign.
This can be achieved by the judicious use of distinct design elements throughout the project. In
a cost sensitive project, forms may be simple, but the sensitive use of massing, scale, and
rhythm can create an architecture that is respectful of, and complimentary to, tne surrounding
architecture of Vail Valley. The exciting architectural design and pedestrian street space wiii
create a of choice for potential employees.
IV. SITE DESCRIPTION AND ENVIRONMENTAL INVENTORY
Location
The subject property is an irregular shaped, approximate 6.5-acre mountainside site; its locationis described as a part of the South Tz of the Southeast % of Section 6, Township 5 South,
Range 80 west of the 6h PM, Town of Vail, Eagle county, colorado. The property adjoins the
existing Mountain Bell property located north of the l-70 North Frontage Road.
Zoninq
A majority of the subject site is presently zoned 'NAPD" (Natural Area Preservation District),
and a small portion of the site where two early learning centers are located is zoned "d';(9eneral). The proposed project will require rezoning the 6.5-acre site to the designation "H'
(Housing).
Site Usase
The property is owned by the Town of Vail. Onsite development includes two small wooden
slruct-ures presently housing early childhood learning centers. They are located direcily east of
the offsite Mountain Bell structure. Site development plans call for demolition of the two early
childhood learning facility structures with construction of a new leaming center at the southeasi
portion of the site. The remainder of the site is undeveloped open land except for the existing
1oa-! 9nd parking area that serves the off-site Mountain Bell facility and the oniiteearly leaming-
facilities. The proposed use of the property was described in section l, above.
Hvdrologic Gonditions
No surface bodies of water are located on the proposed project site. Onsite surface drainage is
mainly via sheet flow and is generally southerly, although the westem portion of the site likely
drains to Middle Creek, located off site just to the west of the entry road. A man-made drainage

channel adjoins the eastern side of the Mountain Bell structure. Soil and drainage issues are
described in reports provided under separate cover by Koechlein Engineering and Peak Land
Consultants, Inc.
Geolosic Conditions
A geologic report by RJ lrish, Consulting Engineering Geologist, Inc. is provided under separate
cover.
Biotic Conditions
Ecologically, the property is located in the Montane Zone at elevations of approximately 8,220 to
8,300 feet above mean sea level on a southerly aspect. Regarding plant communities, the site
is described as complex as it contains elements of several communities. These include
Montane Grasslands and Mixed Mountain Shrubland located on the eastern portion of the
mountainside with Aspen stands occuring at the southeastern portion of the site. These
communities include representatives of most of the life forms of the plant kingdom including
ferns, grasses, forbes, shrubs, and trees. Native and non-native vegetation is present including
invasive species of noxious weeds. The western area of the property is mainly Montane
Riparian Forest dominated by Narrow-leaf Cottonwoods (Populus angustafolia) and a scattering
of Thin-leaf Alder (Alnus incana) and Aspen (Populus tremuloides). Presence of Aspen as weil
as species of invasive weedy forbes indicate the likelihood of past disturbance such as fire.
Climax community species such as Colorado Blue Spruce (Picea pungens) are located off site
higher up the Middle Creek drainage, but Blue Spruce and other climax community trees were
not observed on site.
Wildlife uses the site; large mammals including deer and elk browse on the Serviceberry and
Current located in the Mixed Mountain Shrubland Community. Other mammals including Black
Bear, coyote, Fox, Rabbits, chipmunks, Golden-mantle Ground squirrels, Pocket Gopheis, and
other rodent species likely feed and/or inhabit the site. Reptiles, such as species of Garter
Snakes also likely inhabit the site. No major wildlife migratory roules appear to be located on
site. Although Middle Creek is located off site directly west of the property's western boundary,
the creek is not likely used as a migratory corridor. InterstateT0 and development adjoining the
south side of l-70 preclude use of the corridor for migratory use. Middle Creek is contained
within a culvert from the north side of l-70 to its confluence with Gore Creek south of l-70.
No known threatened or endangered species of plants or animals have been identified at thesite. However, no onsite surveys for such species are known to have been performed. The
Colorado Natural Heritage Program's Conseruation Status Handbook (1999) lists the status of
various animals, plants, and plant communities found in Eagle county. A copy of the Eagle
County list is provided in Appendix A.
We recommend having the Colorado Natural Heritage Program perform a GIS "Environmental
Review" of the subject site and adjacent area. The review searches known ecological
information regarding the status of plants, plant communities, and animals within a specifieO
radius of the subject property. The review will report the status of these communities.
Middle Creek, a relatively pristine stream that likely contains Native Cutthroat Trout, traverses
the adjacent property to the west of the subject site. The creek flows out of a saddle located to

the north upslope from the site. lt flows southerly down slope, jogs west around the Mountain
Bell building, and then flows southerly for approximately 150 feet paralleling the west side of the
entry road to Mountain Bell. lt enters a culvert beneath l-70 and the associated frontage roads
and flows through the culvert south of l-70 to its discharge point into Gore Creek south of the
interstate. Gore Creek flows westerly to its confluence with the Eagle River near Minturn.
The existing creek channel may not be the historic creek channel. Stream modification
(channelization) appears to have been conducted upstream of the culvert adjacent to the entry
road. This 150-foot reach is likely the closest location of the stream to the subject property.
The stream bank, as well as its associated vegetation, appears disturbed along this reach.
Observed vegetation was mainly upland in nature with both native (Western wheat grass-
Agropyron sp.) and non-native species of grasses (brome-Bromus enurmus), as well as
invasive noxious weeds (See Figure 4 photographs, page 2). Upstream from this reach and off
site from the subject property, a riparian corridor of wetland vegetation adjoins the stream
channel.
Adjoining the east side of the entry road, adjacent to its 150-foot north/south orientation, is a
Nanow-leaf Cottonwood (Populus angustifolia) community. This species is referenced in the
U.S. Department of the Interior, Fish and Wldlife Service publication, National List of Plant
Specles That Occur ln Wetlands: lntermountain (Region 8). lts indicator category is listed as
"Facultative", which is described as "Equally likely to occur in wetlands or nonwetlands
(estimated probability 34o/o-66Vo). The presence of this community may be due to a former
location of the stream channel or may be due to high groundwater conditions existing near the
stream channel.
The Nanow-leaf Cottonwood Community conlinues to the north (off site) and south (on site) of
the entry road after the road turns east. Figure 4 Photographs, page 2, depicts the entry road
along its easVwest orientation with the Narrow-leaf Cottonwood Community adjoining both sides
of the road. The presence of this community is an indicator of the potential existence of
wetlands; it does not necessarily confirm their presence. Actual wetland existence can only be
determined by performing a wetland assessment, which not only considers vegetation type, but
also investigates other factors including the presence of hydric soils and wetland hydrology.
Montane Environmental Solutions of Vail, Colorado is presently investigating wetland issues at
the site. A letter regarding the status of their investigation is provided under separate cover.
V. ENVIRONMENTAL CONCERNS AND RECOMMENDATIONS
The proposed Middle Creek Village will impact plant and animal communities presently
inhabiting the property. Site development including earth moving activities and building/parking
lot construction will strip a majority of the existing native and non-native vegetation and displace
wildlife from the approximate 6.5-acre site. However, existing vegetation and wildlife are not
site specific. Surrounding property to the north, east, and west contain vast square miles of
similar plant communities, wildlife habitat, and wildlife species. The loss of these 6.5 acres
does not represent a significant impact to the plant and animal communities. Displaced wildlife
will find and inhabit nearby similar habitat.

Landscaping including grass, shrubs, and trees will cover a minimum of 30% of the developed
site. Middle Creek Village will be sensitively integrated into environmental surroundings. Birds,
insects, and possibly small mammals will utilize the landscaped areas, which will mitigate some
habitat loss.
The presence of Middle Creek Village will have impacts on use of adjacent property by wildlife-
particularly large mammals. lncreased human presence and reflected light may influence
adjoining habitat use. Adjoining property is private so that residents of the village should not be
using adjoining properties. Human/bear interaction is possible. All trash dumpsters will need to
be covered and othenalse made bear proof. Lighting designed to reduce reflected light and
conform to the Town of Vail building code will be incorporated into the site design.
lmpact to Middle Creek from surface runoff will be minimized. Potential impacts include
grease/oil runoff from paved parking areas and sand/gravel runoff from winter sanding of roads.
The location of accumulated snow piles resulting from plowing will be addressed. The piles will
be located such that snowmelt containing grease, oil, silt, sand, and gravel do not impact Middle
and Gore Creeks. Any such contaminants discharged to Middle Creek may impair water
quality of the creek and potentially impact the fisheries of both Middle and Gore Creeks.
Engineered drainage swales, berms, dikes, etc. will be incorporated into the project design to
prevent impact to Middle Creek. Construction will be in accordance with all applicable local,
state, and federal regulations and standards. lf dewatering is required during construction,
water will be retained on site. As previously referenced, drainage issues are addressed in a
report under separate cover.
Montane Environmental Solutions is performing a wetland assessment. As previously
referenced, a potential exists for the existence of jurisdictional wetlands in the vicinity of the
Narrow-leaf Cottonwood Forest located adjacent to the existing access road. The presence of
this community is an indicator of the potential existence of wetlands; it does not necessarily
confirm their presence. We recommend performing a wetland assessment conforming to US
Army Corps of Engineers (The Corps) guidelines. lf on-site wetlands are identified, several
alternatives are available. These include: 1) establishing development setbacks from the
wetlands 2) wetlands can be taken through the 404 Permitting process and replacement
performed to mitigate the loss or 3) if the wetlands are below minimum surface areas
established by the Corps,, they may be removed and built upon. lf on-site jurisdictional
wetlands are identified, The Corps is the agency regulating such matters.
A parking facility is proposed at a location just east of the Mountain Bell structure. Middle Creek
lies north and west of this area. lmpacts to the riparian conidor and wildlife using the corridor
adjacent to Middle Creek will to be minimized. This can be accomplished by constructing the
parking area as far as possible from Middle Creek. Drainage issues as previously referenced
are also a concern in this area of the site. Engineered drainage swales, berms, dikes, etc. will
be incorporated into the project design to prevent impact to Middle Creek.

VI. OTHER ENVIRONMENTAL CONDITIONS
A. Land Acquisitions and Displacements
The impact is "Generally Not Significant".
Approximately 6.5 acres of land is required; the developer/project owner is Coughlin and
Company, 140 East 19thAve., Suite 700, Denver, CO 80203-10gS. fne Town of Vailbwns the
land. lt is proposed that the Town of Vail will lease the site to the developer for a 53-year period
at which time the property will revert to the Town.
Two displacements will result from implementation of the proposed project. The ABC and the
Leaming Tree early childhood learning centers will be displaced. The existing buildings will be
demolished, and new facilities will be constructed at the southeastern portion oi tne site.
State regulations require a full National Emissions Standards for Hazardous Air Pollutants
(NESHAP) asbestos inspection of the buildings prior to demolition. lf the inspection identifies
asbestos-containing materials, regulations require their removal prior to demolition of the
buildings.
No minority communities, households, or minority-owned businesses are located on site, and
therefore, will not be impacted by any potential negative environmental concerns such as noise,
air, or water pollution; or from the construction of the facility.
B. Land Use and Zoninq
The impact is "Generally Not Significant'.
A majority of the subject site is presently zoned 'NAPD' (Natural Area Preservation District),
and a small portion of the site where two early learning centers are located is zoned G. Th;
proposed project will require rezoning to the designation ,,H,' (Housing).
C. Visual Conditions
Parking areas will be located behind housing thereby shielding it from view from the Town ofVail. Overall project form and massing is in character with existing Vail Village. The height,
mass, and materials that will be used in the proposed Middle Creek Village will convey a sense
of permanence and contextual and regional appropriateness.
D. Air Qualitv
The impact is "Generally Not Significant'.
The project will conform to all applicable local, state, and federal air quality regulations and
standards, including, but not limited to those regulating odor, dust, fumes of gases, which are
noxious, toxic, or conosive, and suspended solid or liquid particles.

Fireplaces will not be installed in the developmentthereby eliminating wood smoke. There will
be no balconies or decks that would provide space for grills or barbecues. There may be a grill
in a public area of the complex.
The Middle Creek Village project is designed to discourage vehicle usage and encourage other
modes of transportation such as buses, biking, and walking. TDA of Colorado performed a
transportation impact analysis regarding the proposed Middle Creek Village. Their report is
provided under separate cover. The report indicates that the impact of traffic generated by the
proposed project will be "Generally Not Significant".
E. Noise
The impact is "Generally Not Significant'.
Stewart Environmental identified no noise-sensitive land uses on adjacent properties. The
proposed site is located adjacent to the north side of l-70. The noise from the interstate is far
greater than any that would be produced by the development.
F. Lisht Pollution
The Middle Creek Village development will have minimal light trespass from the residential
buildings.
G. Floodinq
The impact is'Possibly Significant".
Peak Land Consultants, Inc. addresses flooding issues in a report provided under separate
cover.
H. Navigable Waterwavs and Coastal Zones
The impact is'Generally Not Significant".
The proposed site is not located near or affected by a navigable waterway or a coastal zone.
l. Traffic and Parkinq
The impact is'Generally Not Significant".
TDA of Colorado performed a traffic study. Their report is provided under separate cover.
J. Energy Requirements and Potential for Conservation
The impact is'Generally Not Significant".

Leadership in Energy and Environmental Design (LEED) rating system is here used as a
preliminary sustainable design measure of the project. As it is currently written, LEED version
2.0 is a system designed to rate new and existing commercial, institutional, and high-rise
residential buildings. lt specifically rates low-rise residential projects. The USGBC is currently
developing a residential version of the LEED rating system. Nevertheless, the sustainable
design principles embodied in LEED v. 2.0 serves as useful goals, guidelines, and measure for
sustainable features of the Vail Affordable Housing Project.
The LEED rating system consists of seven prerequisite criteria and 32 user-selected criteria
organized into five categories:
r Sustainable Site Developmentr Water Efficiency. Energy and Atmosphereo Materials and Resourceso Indoor Environmental Quality
LEED is a voluntary, consensus-based, market-driven building rating system based on availableproven technology that evaluates environmental performance from a 'whole building"
perspective over a building's life cycle. The following preliminary LEED analysis incorporates
input from the design team to more accurately evaluate the conceptual design of the Vail
Affordable Housing Project.
K. Construction
The impact is "Generally Not Significant".
Construction of the Middle Creek Village is anticipated to commence in March 2OO2 and will last
for approximately 18 months, therefore any construction impacts will be temporary and of short
duration. All construction staging will be located on site and construction activities
predominantly will be confined to this site.
Contractors will be required to obtain the necessary permits and comply with all relevant town,
state and federal regulations regarding construction and safety. Potential construction impacts
are described below.
Noise
No noise-sensitive land uses are located on adjacent property. Construction hours and
noise levels will comply with the Town of Vail policies.
Disruption of Utilities
It is anticipated that there will be no disruption of utilities, and therefore no significant
impact with this activity. Construction of all utilities to serve the site will be contained
within the proposed site.

Demolition of two buildings is required as previously referenced. All construction debris
will be disposed at an approved landfill and transported on designated truck routes. The
general contractor will be responsible for on-site cleanup and disposal of debris.
Soilfillmay be required to elevate buildings abovethe 10O-yearflood plain. Disposalof
soil is not required.
Water Qualitv and Runoff
Project construction will not impact existing water quality. The general contractor will
comply with water quality requirements for site construction to meet state water quality
regulations. Best Management Practices (BMPs) will be implemented during
construction including the use of erosion control measures.
Access and Disruption of Traffic
City streets will not have any significant impact since the site is located directly off the l-
70 North Frontage Road. Any frontage road diversions will be addressed with a detour
plan.
Air Qualitv and Dust Control
Standard construction practices and BMPs will be used to control and minimize onsite
dust and emissions.
Safetv and Securitv
Standard construction safety measures will be observed on site. Town of Vail police will
ensure security.
Disruption of Businesses
No businesses are located in the immediate vicinity of the project area.
L. Aesthetics
The impact is "Generally Not Significant'.
The height, mass, and materials that will be used in the proposed MiddleCreek Village will
convey a sense of permanence and contextual and regional appropriateness. In addition, the
facility design will promote an orderly circulation and efficient integration of buses, other
vehicles, and pedestrians.
M. Communitv Disruption
The impact is "Generally Not Significant'.
No businesses or residential sectors will be disrupted or displaced, and no segments of the
community will be isolated as a result of this proposed project.

Findinqs, Conclusions. Opinions and Recommendations
The proposed Middle Creek Village development is located adjacent to the Mountain
Bell facility, directly north across Interstate 70 from Vail Village. The proposed project
consists of multi-family housing constructed on a 6.5-acre site owned by the Town of
Vail. The project will not promote secondary development. The purpose of the project is
to provide affordable housing for people currently employed in Vail who are presenfly
living in or near the community. The project owner is coughlin and company, 140 East
19"' Ave., Suite 700, Denver Colorado 80203-103S.
A majority of the subject site is presently zoned 'NAPD" (Natural Area Preservation
District), and a small portion of the site where two early learning centers are located is
zoned G. The proposed project will require rezoning to the designation "H' (Housing).
Environmental issues regarding the proposed project are addressed in reports provided
under separate cover. These include a) geologic hazards - RJ lrish, Consulting
Engineering Geologist, lnc., b) drainage issues- Peak Land Consultants, Inc., c) soils -
Koechlein Engineering, and d) traffic - TDA of Colorado.
wetland issues were identifled and are addressed within this report. Montane
Environmental Solutions of vail, Colorado is presenfly performing an in-depth
investigation of the wetland issues. A letter regarding the status of their investigation is
provided under separate cover.
Wildlife uses the site; large mammals including deer and elk browse on the Serviceberry
and Current located in the Mixed Mountain Shrubland Community. Other mammals
including Black Bear, Coyote, Fox, Rabbits, Chipmunks, Golden-manile Ground
Squirrels, Pocket Gophers, and other rodent species likely feed and/or inhabit the site.
Reptiles, such as species of Garter Snakes also likely inhabit the site. No major wildlife
migratory routes appear to be located on site. Although Middle Creek is located off site
directly west of the property's western boundary, the creek is not likely used as a
migratory corridor. InterstateTO and development adjoining the south side of l-70
preclude use of the coridor for migratory use. Middle Creek is contained within a culvert
from the north side of l-70 to its confluence with Gore Creek south of l-70.
No known threatened or endangered species of plants or animals have been identifled at
the site. However, no on-site surveys for such species are known to have been
performed. The Colorado Natural Heritage Program's Conservation Status Handbook
(/999) lists the status of various animals, plants and plant communities found in Eagle
County. A copy of the Eagle County list is provided in Appendix A.
We recommend having the Colorado Natural Heritage Program perform a GIS
"Environmental Review" of the subject site and adjacent area. The review searches
known ecological information regarding the status of plants, plant communities and
animals within a specified radius of the subject property. The review will report the
status of these communities.
The proposed Middle Creek Mllage will impact plant and animal communities inhabiting
the property. Site development including earth moving activities and building/parking lot

construction will strip a majority of the existing native and non-native vegetation,
including noxious weeds, and displace wildlife from the approximate 6.5-acre site.
However, existing vegetation and wildlife are not site specific. surrounding property to
the north, east and west contain vast square miles of similar plant communities, wilOtfe
habitat and wildlife species. The loss of these 6.5 acres does not represent a significant
impact to the plant and animal communities. Displaced wildlife will find and inhabit
nearby similar habitat.
The presence of Middle creek Village will have impacts on use of adjacent property by
wildlife, particularly large mammals. Increased human presence and reflected light ;nay
influence adjoining habitat use. Adjoining property is private so that residenti of thb
Village should not be using adjoining properties. Human/bear interaction is possible. All
trash dumpsters will need to be covered and othenivise made bear proof. Lighting
designed to reduce reflected light and conform to the Town of Vail building coOe witt Oe
incorporated into the site design.
lmpact to Middle Creek from surface runoff will be minimized. Potential impacts include
grease/oil runoff from paved parking areas and sand/gravel runoff from winter sanding of
roads. The location of accumulated snow piles resulting from plowing will be addressld.
The piles will be located such that snowmelt containing grease, oil, silt, sand, and gravel
do not impact Middle and Gore Creeks. Any such contaminants discharged to MiOdle
lreek may impair water quality of the creek and potentially impact the fisheries of both
Middle and Gore creeks. Engineered drainage swales, berms, dikes, elc. will be
incorporated into the project design to prevent impact to Middle Creek. Construction will
be in accordance with all applicable local, state, and federal regulations and standards.
lf dewatering is required during construction, water will be retained on site.
10.A parking facility is proposed at a location just east of the Mountain Bell structure.
Middle Creek lies north and west of this area. lmpacts to the riparian corridor and
wildlife using the corridor adjacent to Middle Creek will to be minimized. This can be
accomplished by constructing the parking area as far as possible from Middle Creek.
Drainage issues as previously referenced are also a concern in this area of the site.
Eng.ineered drainage swales, berms, dikes, etc. will be incorporated into the project
design to prevent impact to Middle Creek.
11. Two displacements will result from implementation of the proposed project. The ABC
and the Learning Tree early childhood learning centers will be displaced. The existing
buildings will be demolished and new facilities will be constructed at the southeastern
portion of the site.
State regulations require a full National Emissions Standards for Hazardous Air
Pollutants (NESHAP) asbestos inspection of the buildings priorto demolition. lf the
inspection identifies asbestos-containing materials, mitigation (abatemenUremoval) per
regulations will be performed prior to demolition of the buildings.

Dear Mr. Odell,
At you request Montane Environmental Solutions Ltd (Montane) visited the
proposed affordable housing development located at the'Mountain Bell site', on
August 23rd, 2oo1. The purpose of the visit was to review an area identified in the
draft Environmental Impact Report (EIR) as a narrowleaf cottonwood
community with a potential for containing wetlands.
It was our finding that although not extensive, there were some areas of the
woodland that did have the potential for being wetlands. To identify wetland
areas areas, we propose to conduct a jurisdictional wetlands delineation in a
format acceptable to the US Army Corps of Engineers (Corps).
From our visit yesterday it appeared thatjurisdictional wetland areas (areas
under the jurisdiction of the US Army Corps of Engineers) are probably rather
limited and would therefore be likely to fall into the 'Nationwide Permit' category
of federal permitting. The Nationwide Permit system is a streamlined permit
system for small impacts, not considered to be of significant environmental
impact.
Do not hesitate to call if you have any more questions. We look forward. to
working with you further on this project
Sincerely
Nicola Rlplev

Subject: Preliminary Geotechnical Investigation and Geologic Hazard Studies
Proposed Development - 6.5 Acres
Middle Creek Village at Vail
Vail, Colorado
Job No. 01-136
As requested we have performed a preliminary geotechnical investigation and geologic hazard study for
the subject propefiy. The purpose of this letter is to present our general conclusions regarding the
preliminary geotechnical investigation and geologic hazards.
We anticipate that the subsurface conditions throughout the development will consist of granular alluvial
soils. These soils should safely support spread footing foundations and slab-on-grade floors for the
proposed structures. Excavation of these soils will require heary-duty construction equipment. It is our
opinion, that development of this site will require typical mountain construction techniques.
Based on current and previous geologic hazard studies, the subject site is within a rock fall hazard and a
debris flow hazard. Fortunately, both of these geologic hazards can be successfully rnitigated. For
additional information regarding preliminary geotechnical recommendations and geologic hazards refer
to our Preliminary Geoteclmical Investigation and Geologic Hazard Studies report, dated August 23,
2001.
We appreciate the opportunity to provide this service. If we can be of further assistance, please contact
our office.

SCOPE
This report presents the results of a preliminary geotechnical investigation for the
proposed commercial development of 6.5 acres located in the Mountain Bell Site in Vail,
colorado. The approximate site location is shown on the vicinity Map, Fig. l. The
purpose of the investigation was to evaluate the subsurface conditions at the site and to
provide preliminary geotechnical recommendations for the proposed development.
This report includes descriptions of anticipated subsurface soil and ground water
conditions based on adjacent properties and our experience with similar projects, the
geotechnical conditions influencing the proposed development and recommendations for
development of the site. This report presents anticipated subsurface conditions tbr the
proposed development. Site speciJic geoteclmical investigations should be performed for
individual building sites and pavement subgrade, as recommended in this report.
A summary of our investigation findings and conclusions is presented in the
following section.
EXECUTIVE SUMMARY
l. Based on adjacent properties and our site reconnaissance, we anticipate
that the subsurface conditions will consist of either topsoil or existing fill
underlain by alluvial soils. The alluvial soils should be characterized by
medium dense to dense, sand and gravel with cobbles and boulders. we
anticipate that the existing fill will be characterized by a loose to medium
dense, sand and gravel with cobbles.

Because Middle creek appears to have been rechanneled to its current
Iocation, it is possible that ground water could be encountered in isolated
underground channels throughout the proposed development. Refer to the
GROUND WATER section of this report for additional details.
Two buildings with associated amenities and utilities are currently located
on the subject site. All existing foundations, slabs-on-grade, utilities and
associated filI should be removed to expose the natural soils prior to
construction of the proposed development.
Based on our site reconnaissance, we anticipate that existing frll will be
encountered during construction of the subject project. we believe that
the existing fill will be characterized by sand and gravel with cobbles and
boulders. In our opinion, the existing fill, free of deleterious material, may
be used as structural fill for the development ofthe project.
In our opinion, the proposed buildings within the development may be
supported by spread footing foundation systems bearing on the natural
sand and gravel soils. However, because these soils are alluvial soils,
differential settlements are possible. Refer to the FOUNDATION section
of this report for more infonnation.
In our opinion, the natural sand and gravel anticipated throughout the
development will support slab-on-grade floors. Refer to the FLOORS
section of this report for more information.
cuts up to l0 feet in height may be necessary along the access road to the
proposed parking structure. Large cut slopes, greater than l0 feet, will
need to be evaluated by a Professional Geotechnical Engineer. Refer to
the EXCAVATION section of this report for additional cut slope
recommendations.
Retaining walls and fills may need to be constructed along the proposed
southem parking lots. Refer to the SITE woRK section of this renort for
additional details.
utilities will be installed for the proposed development. Because cobbles
and boulders are anticipated throughout the development, it is our opinion
that heavy-duty excavation equipment will be required to complete
excavations within the proposed development.

development. The paved roads may include both rigid and flixible
pavements. Preliminary pavement recommendations based on anticipated
subsurface conditions are presented in the pAVEMENT DESIGN section
ofthis report.
SITE CONDITIONS
The proposed development is to be located on 6.5 acres in the Mountain Bell Site
in Vail, Colorado. The site is bordered by the North Frontage Road West to the south and
partially by Mountain Bell Road to the north. The Mountain Bell Tower borders the site
to the west while open space will border the site to the east. The subject site is shown on
the Site Plan, Fig. 2. Two existing buildings with associated arnenities and utilities are
located on the subject site. The buildings are single-story buildings and are of wood
frame construction. Because of the previous developrnent on the site, existing fill was
observed tkoughout the proposed developrnent in the area of the existing buildings.
Existing fill was not observed in the area south of Mountain Bell Road. The topography
of the site consists of moderate slopes of 5 to 10 percent to steep slopes of 15 to 20
percent. The overall drainage ofthe site is generally to the south. Vegetation on the site
consists of grasses, bushes, trees and aspen trees.

PROPOSED DEVELOPMENT
The project consists of the development of 6.5 acres in the Mountain Bell Site in
vail, colorado. A preliminary site plan for the proposed deveropment was provided by
the Architect prior to our investigation. The preliminary development plan is shown on
the Site Plan, Fig. 2. we understand that the proposed deveropment may consist of
townhouse type, multi-family, commercial buildings with associated access drives and
parking lots. The buildings will be constructed south and southeast of Mountain Bell
Road. Parking areas for the proposed buildings will be constructed to the south of the
buildings and to the north of the proposed buildings. We understand that the parking area
constructed to the north of the buildings may consist of a twolevel parking structure with
the top level being at grade. we understand that the multi-family buildings will vary
from 2 to 4 stories in height and will be stepped to match the existing ground surface. By
stepping the proposed structures with the existing ground surface, we anticipate that
maximum excavations of only i0 feet in depth may be required. we anticipate that
pennanent cuts and fills will be required for construction of the proposed development.
Maximum wall loads were assumed to be those normally associated with multi-family
commercial construction.

GEOLOGIC HAZARD STUDIES
A current geologic hazard study was perfonned for the proposed development in
order to identify any geologic hazard that may exist on the subject site. The Geologic
Hazard study was prepared in August of 2001 by R. J. Irish Engineering Geologist and is
presented in Appendix A.
In addition to the geologichazard, study prepared by R. J. Irish, previous geologic
hazard studies for the area have been prepared. Three previously prepared geologic
hazard studies or summaries are presented in Appendix B.
INVESTIGATION
Because of the existing buildings, shrubs and trees on the subject site, access to
the site with excavation or drilling equipment is extremely difficult. In order to obtain
access to the site, an access road must be constructed through the proposed development.
Because of the inaccessibility of the site, exploratory test pits orborings were unable to
be excavated or drilled on the subject site. In order to obtain a general idea of the
subsurface conditions throughout the subject site, an engineer from our office
reconnoitered the site on August 14, 2001, The engineer observed the subsurface
conditions exposed within cut slopes throughout the proposed development and observed
the soils on the exposed ground surface. The subsurface conditions observed during our
field reconnaissance were compared to subsurface conditions encountered durins our

FOUNDATIONS
We anticipate that the materials at potential foundation elevations will consist of
either existing fill or sand and gravel with cobbles and boulders. In our opinion, the
existing fill will not safely support fbundations for structures within the proposed
development' Therefore, all existing foundations and associated filI must be removed
from the proposed development prior to construction.
We believe that the anticipated sand and gravel r.vill safely support spread footings
for the proposed buildings within the development. However, because the anticipated
natural soils are alluvial soils it is possible that loose, silty sancl pockets or layers could
be encountered beneath the proposed development. Foundations constructed on these
types of soils can experience large differential settlements. Provided that no loose sand
pockets or layers are encountered beneath the proposed foundations, it is our opinion that
the anticipated sand and gravel will safely support spread footings for the proposed
buildings within the development. We anticipate that spread footing foundation systems
for the buildings within the proposed development may be designed with a maximum
allowable bearing pressure varying from 2,500 psf to 6,000 psf. The allowable bearing
pressure will depend on the amount of cobbles and boulders within the building envelope.
The maximum allowable bearing pressure can be better defined during the site specific
investigations.

FLOORS
The materials at the potential floor slab elevations may consist of topsoil, existing
fill or sand and gravel. In our opinion, the existing fill or topsoil will not safely support
slab-on-grade floors. However, the natural sand and gravel will safely support slab-on-
grade floors with a low risk of movement. The presence of loose, silty sand pockets or
layers will have less of an impact on slab-on-grade floors. However, if these pockets or
layers are encountered, they should be removed and replaced with properly moisture
conditioned and comoacted fill.
UTILITY CONSTRUCTION
Construction of utilities below grade will require the excavation of the near
surface soils, We anticipate these soils will consist of topsoil or existing fill underlain by
sand and gravel with cobbles and boulders. Because cobbles and boulders are
anticipated, it is our opinion that heavy-duty construction equipment will be required to
complete the necessary excavations for utilities. Sand and gravel soils without ground
water classify as Type B soils in accordance with OSHA regulations. OSHA regulations
should be followed in any excavation.

construction of buildings and access roads may require cuts and fills to
obtain the desired grades. Any cut or fill slopes greater than l0 feet in height should
be evaluated by a Professional Geotechnical Engineer. Retaining wall systems may
be required in some areas to reduce the extent of cuts and fills. we anticipate that
on-site sand and gravel may be used in fill areas. proper moisture treating of the
natural soils will be required prior to or during placement and compaction of fill.
surface drainage should be carefully evaluated during design and
construction of the proposed development, Slopes around retaining walls and
buildings should be graded so that positive drainage is maintained away from these
structures.
Cut Slopes
Any cuts, which are greater than 10 feet in height, shourd be evaluated on an
individual basis. If requested, we can perform the evaluation of these slopes. In
general, slopes of2:l (horizontal to vertical) up to l0 feet in height should be stable
on the subject site, if properly drained. Surface drainage should be carefully
designed to divert surface water away from the slopes. All cut slopes should be
vegetated as soon as possible after construction.I.

Fills over l0 feet may be required for this developrnent. Any filr slope
greater than l0 feet in height should be evaluated on an individual basis. If
requested, we can perform the evaluation of these slopes. In general, filI slopes of
2:l (horizontal to verticai) up to l0 feet in height should be stable, if properly
drained. Fill may consist of anticipated on-site sand and gravel free of deleterious
materials or an approved imported granular fill. No cobbles or boulders larger than
12 inches should be placed in fill areas. Fill areas should be stripped of all
vegetation, topsoil, existing foundations and existing fill. The resulting surface
should be scarified and properly moisturc conditioned and compacted. Fill should be
placed in thin loose lifts, moisture conditioned to within 2 percent of optimum
moisture content and compacted. The degree of compaction will vary depending on
the use of the fill.
Retaining Walls
Retaining walls may be needed to reduce the magnitude of cuts or fills for
development of this site. The types of walls that are possible on this site are
conventional concrete retaining walls, MSE (mechanically stabilized earth) wails,
timber crib walls and boulder retaining walls. The retaining walls need to belr

designed to resist laterai earth pressures. Lateral earth pressures depend on the type
of backfill, slope of ground surface behind the retaining wall, height of retaining
wall, and type of retaining wall. we can provide the design, or the geotechnical
design criteria, for the retaining walls once the specific site conditions and proposed
construction are finalized.
SITE DRAINAGE
Surface drainage should be carefully evaluated during design and construction of
the development. overall drainage of the site is generally down to the south.
Construction areas should be carefully sloped to reduce the possibility of infiltration of
surface water into the cut and fill slopes. In addition, slopes around retaining walls and
buildings should be graded so that positive drainage is maintained away frorn these
structures at all times. The surface drainage of the development should be evaluated prior
to establishing final grades.
PRELIMINARY PAVEMENT DESIGN
It is anticipated that the roads and parking areas within the development will be
paved' Based on the subsurface conditions, it is our opinion that flexible asphalt and
rigid concrete pavements are possible. It has been generally found that concrete
pavements tend to perform better than an asphalt and base course pavement. The initiallo

costs are generally higher for concrete pavements, however, the long term malntenance
costs are less.
We anticipate that both flexible pavement and rigid pavement could be used at
this site. we recommend that rigid pavement be used in high traffic areas such as
entrances or where heary vehicles (trash trucks, delively trucks, etc.) tum or maneuver.
Two preliminary pavement sections based on high volume traffic and low volume traffic
are presented for the flexible pavements. High volume traffic areas are considered to be
access roads or fire lanes. Low volume traffic areas are considered to be parking areas.
The following sections present design assumptions and preliminary flexible and rigid
pavement sections. ht order to properly design the reEdred pavement sections, we
recommend when final subgrade elevations have been achieved, a Jinal subgrade and
p av e ment inves t i ga t i o n b e p erformed.
Preliminary Flexible Pavement Desig4
The design of the preliminary flexible pavement was based upon an
Equivalent Daily Load Application (EDLA), anticipated soil properties and the
colorado Department of Transportation pavement design manual, preliminary
design calculations were based on assumed engineering soil characteristics. Based
visual observations of the surface soils and review of soil investigations in the area,
we anticipate that the subgrade soils will classifu as A-l-b soils, as defined by the

AASHTO classification system. The preliminary pavement designs are based on the
subgrade soils having an AASHTO classification of A-l-b. This soil type will
generally have a Hveern stabilometer R-value ranging from 50 to 75. The R-value
was estimated fi'om the AASHTO classification of the soil. Because the R-value of
the natural soil was assumed to be 50 to 75, the use of roadbase will not reduce the
pavement thickness. However, roadbase may be required to establish a finished
grade prior to paving. The EDLA for high volume traffic for residential
developments was assumed to range from l0 to 20. The EDLA for low volume
traffic was assumed to range from 3 to 5. Two flcxible pavement designs, based on
the above method, are shown below in Table A. These flexible pavement designs
include two fulI depth asphalt pavements.
A preliminary rigid pavement section was designed using the same values of

Re: Engr. Geologic Hazard Study, Middle Creek Village at Vail Development, Vail, Colorado.
Job No. 564
Gentlemen:
In response to your call, we have geologically reconnoitered. the site in Vail, Colorado,
planned for the Middle Creek Village at Vail Development, which is to incorporale atfordable,
multi-family housing and appurtenait facilities on about I acres. This irregularly shaped tract is
rociieO in i part otine StiZ SE1/4 Sec. 6, T. 5. S., R. 80 W', Eagle C9!1V' Colorado, north of
the north service road immediately west of the Old Vail/lnterstate Highway l-70 exit'.and
aOlacent to an existing Mountain Beiltelephone tower (Fig. 1). lt lies at the foot of the northern
slope of the west-treniing Gore Creek Vailey where that slope is breached by a canyon section
ot ine UiOOte Creek Valle-y. The ground surfice across the property slopes generally southward
at about 10:1 (horiz. to vert.ltroir etev. 8290 feet to Elev. 8220feet. The western twothirds of
the property ii forested witir aspen and scattered evergreens' Some of the latter are quite
large. ihe iastern third ofthis tract is covered by sagebrush and other brush types.
Our objective has been two-fold: 1.) to generally delineate.geologic conditions across the
property and immediate vicinity, and to'eval-uate the probable influences those conditions will
irave on the planned construction, with special reference to geologic hazards, such as
landslides, debiis flows, and rock falls, that could impede the development of the property; and'
2.) conversely, to assess the probable impact of the planned construction on the natural
g;of"g; tonciiiions. An ancillary goal has been to suggest means to ameliorate the risk posed
by any geologic hazards that may be discovered.
During the course of our work we have stereoscopically examined aerial photographs of th-e
property a-nd vicinity, and have geologically reconnoitered the site and vicinity (on August 15'
locjt ).
'orr interpretations of geitogijconditions across the site and vicinity are illustrated by a
geologic map, Figure 1 (attached),
We conclude that the tract to be occupied by the Middle Creek Village at Vail Development
is subject to debris itows perioOically emanatingifrom the valley of .Mill,Creek, as well as rock
falls from lhe lower part of the adjicent sectoi of the steeply inclined, northern slope of the
Eagt" Cr"ef Valley. We assess the debris flow risk to be high, and the rock fall hazard to be
medium. The former risf, we believe, could be substantially reduced one or more of several
jtternative mitigating measures, These could be selected and designed when the final plans
for the project ire OiveiopeO. The latter risk could be reduced materially by hand-dislod.ging
boulders, ittowing them to roll down the hill and onto the floor of the debris fan before buildings
are constructed on this site.

The Gore Creek Valley has been eroded into the interbedded sandstones, siltstones,
shales and limestones of the Pennsylvanian-age (about 325 to 286 million years ago) Minturn
Formation by both streams and glaciers. Glaciers repeatedly occupied the valley of Gore Creek
during the lce Age, which began about 2 million years ago, and terminated only about 8,000
years ago in this part of the Rocky Mountains. The glaciers deposited morainal soils across the
lower slopes of the valley and both glacial outwash and morainal soils across the valley floor,
aggrading it by as much as 100 feet or more. The upper reach of the Mill Creek Valley was
occupied repeatedly by glaciers also, as evidenced my multiple cirques at the head of the
Valley, and a U-shaped transverse topographic profile that extends down valley to about the
Elev. 9800-foot contour. That contour crosses the floor of the canyon about 2 miles upstream
from the junction of that valley with the Gore Creek Valley.
The morainal soils generally are an heterogeneous, medium dense to dense, mixture of
sands, gravels, cobbles, and scattered boulders in a silt matrix. Mostly the soils are granitic
rock debris, but include sandstone, siltstone, and limestone debris as well. The permeability of
this soil typically is low, on the order of 10's cm./sec., but may include lenses of much more
permeable sands and gravels. The soils deposited by glacial meltwaters (the glacial outwash
deposits) typically are interbedded, medium dense to dense sands and sandy gravels that
commonly are cobbley and bouldery. These typically are quite permeable, on the order of
l0-2 cm./sec. to 10{'cm. sec. The morainalsoils blanketing thetoe of the northern slope of the
Eagle Valley adjacent to this property are estimated to range from about 5 feet to 20 feet thick.
Since the end of the lce Age, fast-moving floods charged with soil and rock debris
(essentially mud flows) repeatedly have coursed down the Middle Creek Valley, and have
deposited their bed loads out across the floor of the Gore Creek Valley at the confluence of
those valleys where the Middle Creek Village at Vail Project is to be sited. Those flows are
referred to as debris flows. Moreover, many "normal" floods have carried soil and rock debris
out onto the floor of the Eagle Valley at this confluence, as well.
In consequence, a debris/alluvial fan has been constructed at the mouth of the Mill Creek
Valley. lt is about 2000 feet long along its toe, and about 1200 feet wide from its apex in a
canyon section of that valley to its toe adjacent to Gore Creek. lt is expected to be formed of
torrentially interbedded loose to dense, sands, gravels, cobbles and boulders in a silty matrix.
The soils, granitic metamorphic rock, sandstone, and siltstone debris, are expected to both
overlie and interlense with the morainal, alluvial and glacial outwash soils underlying the floor of
the Gore Valley. These fan soils probably range to several tens of feet thick across the center
of the fan.
The permeability of these debris/alluvial fan soils probably ranges widely, due to a widely
ranging "iines" content, from an estimated 10'3 cm./sec. to 10'5 cm. sec. The ground water table
in these soils probable lies about ',|5 feet below the ground surface at the southern edge of the
property, but probably is much deeper in the head area of the fan.
The interbedded, fine grained and flne to coarse grained sandstones, siltstones, shales and
microcrystalline to very fine grained limestones of the Minturn Formation crop out sporadically
across the foot of the northern slope of the Gore Creek Valley adjacent to, and within the

canyon section of Mill Creek Valley. These are relatively well indurated, strong, hard rocks.
Their unconfined compressive strengths, we estimate, range from about 10,000 psi to 15,000
psi for the sandstones and siltstones, 25,000 psi to 30,000 psi for the limestones, and 5,000 psi
to 8,000 psi for the shales. The shales are only poorly fissile. These strata are thin to thick
bedded, and their near-vertically dipping joints typically are several feet to 10 feet apart. The
beds strike north-northwestward and dip about 25o west-southwestward, thus nearly parallel to
the contours of the valley slope, rather than out of the slope. These rocks, including the
sandstones, have very little, if any, intergranular permeability, but ground water undoubtedly
flows along some of the joint planes.
No faults are known to us to disrupt the bedrock strata underlying the project area, but
several have been reported in the vicinity. These are believed to be inactive.
Assessment of Geologic Hazards
Debris flowage is the principal geologic hazard attendant to the Middle Creek Village at Vail
site. In fact, this site effectively spans the upper sector (i. e., uphill sector) of the debris/alluvial
fan, thus could be flooded if a debris flow or "normal" flood should leap the banks of the channel
of Middle Creek at the apex of the fan at the mouth of that valley. A debris fan is deposited by
multiple debris flows, which are high-energy flows of surface water charged with soil and rock
debris. The flow is debouched from a steep-floored ravine onto the floor of a main valley, where
its bed load is deposited to form part of a fan-shaped deposit, the debris fan. Typically a debris
1ow is initiated by localized, high intensity rainfall that quickly washes loose soil and rock from
the catchment area of a ravine or canyon. This debris is carried essentially as a mud slurry.
Commonly the debris flows and the companion flood flows abandon the channel occupied by
the creek on a debris/alluvial fan, spread out across the fan surface, and even create new
channels during some events. These flows, both debris and "normal'flood flows, can seriously
damage or deJtroy buildings and their infrastructure, as well as harm the occupants of those
buildings.
We assess the risk of debris flows from the Middle Creek Valley to be highl during the
lifetime of the project, although we cannot predict their average recurrence time interval'. That
recurrence time interval is likely to be quite erratic. Their volumes could range from small to
quite large because the drainage area of Middle Creek incorporates about 6 to 7 square miles.
The high risk posed by debris flows, as well as by "normal" floods, could be reduced by one
or a combination of several mitigating measures. The designs for these could be incorporated
in your final development plans.
Additionally, debris fan soils tend to be subject to differential settlement when wetted, but
the potential impact of this can be moderated by foundation engineering practices well within the
state-of-the-geotechnical engineering practice.
' Our assessment of risk is couched in qualitative, empirically-derived terms (high, medium, and low).
The state-of-the-geologic-art does not permit a rational quantitative analysis,
2 An experiencei engineering hydrologist should evaluate the risk of "normal" flooding.

Large and small boulders of granitic rock and limestone are scattered across the steeply
inclined surface of the foot of the valley slope overlooking the eastern half of the project area.
Most of these appear to be embedded in the morainal soils that blanket that area, but a few
appear to be perched on top of that ground. Both could be dislodged by slopewash erosion,
thus could tumble down into the project area.
We consider the risk of such an event to be medium during the lifetime of the project. That
risk could be reduced substantially, we suggest, by dislodging the exposed boulders by hand,
utilizing a steel bar, and allowing them to fall onto the surface of the debris fan down slope
before any buildings are constructed on this tract. The area to be serviced extends from the
northern side of the fan surface up to a terraced section of the slope about 150 feet in elevation
above the fan surface, and from the eastern side of the property to the eastern side of the
mouth of the Middle Creek Valley,
Boulders perched on, and partly embedded in the morainal soils across the toe of the Eagle
Valley slope west of the mouth of the Mill Creek Valley may be dislodged naturally from time to
time and roll down the slope, but they should not travel into the western section of the planned
development area. Instead, they are likely to be trapped in the channel of the creek, which
traverses along the toe of that slope. Any that may skip over that channel, however, should be
trapped by the dense brush and aspen west of the Mountain Bell tower, or impeded by the
tower buildings.
The soils and rock underlying the Eagle Valley slope in the vicinity of the planned
development site appear to be relatively stable. We observed no landslides there or ground
surface cracks that might presage landsliding. The granular soils of the shallow sloped
debris/alluvial fan do not evidence instability or incipient instability.
The 4O-mile long Gore Fault, a major mountain-bounding structure on the western side of
the Gore Range, lies about 4 miles east of the project site (at its closest approach); the SO-mile
long Mosquito Fault lies about 12 miles to the west; and the 25-mile long Sawatch Fault
terminates (at its northern end) about 24 miles soulh of the site. Some seismologists consider
these 3 faults to be potentially active; but most seismologists, nonetheless, consider the risk of a
strong earthquake generated by those faults or any other fault within a hundred miles of the
project site to be low to insignificant during the next 100 to 200 years. This is not to say that this
part of Colorado is seismically quiescent, but the earthquakes generated by the reactivation of
faults in this region should have small magnitudes. Earthquake intensities of V to Vl, with peak
accelerations of 0.059, we conclude, are unlikely to be exceeded at this site during the life of the
project.
So long as the construction of the planned buildings and appurtenant facilities does not
materially change the existing ground conditions of the natural soils and/or bedrock, slope
stability should not be impaired. lf cuts or fills in excess of 5 feet high are needed, however,
they should be designed by a geotechnical engineer experienced in that work. Ponding of water
on the debris/alluvial fan slope, of course, should be avoided because seepage water from a
pond could build pore water pressure in the debris fan soils, thus could trigger ground
movement.

Re: Vail-Middle Creek, Trafftc
Dear Lee,
As agreed, we have prepared this initial review of traffrc issues associated with development of
I 50 to 200 affordable housing units in the town of Vail along North Frontage Road, west of the
Vail Road north roundabout. We will follow this initial review with a detailed traffic impact
a$sessment at a later date as the project proceeds through the Town of Vail's development
review process. At this time our review covers two site planning considerations: potential
vehicle trips generated by this project and, site access and circulation
Vehicle Trip Generation
We understand the project will be up to four stories, specifically zoned as Affordable Housing.
Occupants of the studio, one- or two-bedroom dwellings will be seasonal workers primarily,
employed in the Vait Valley. The approximately 6.5-acre parcel will also have a freestanding
early childhood learning center. This will replace an existing day care facility on the property.
Most of the parking will be located in the hillside behind the clustered housing units, east ofthe
existing Mountain Bell tower.
Typically, a multi-family clustered development ofthis type could be expectedr to generate
,rihicle trips at a rate of 6 to 7 trips per unit per day. Entering and leaving the site is two trips,
one in and one out. If the site were to have 200 dwelling units perhaps up to 700 vehicles would
enter and leave the site each day; yielding 1,400 vehicle trips daily based on typical trip
generation characteristics.
However, we believe actual vehicle trip activity at full occupancy would be noticeably less than
the typical suburban townhome or apartment complex. We believe walk, bike and public transit
will substirute for many of what otherwise would be local vehicle trips, Reasons for this are:
Reduced Auto Availabitiry -Many of the occupants will be seasonal and local workers.
Auto ownership will be relatively low with many seasonal residents relyrng on public
transportation or carpooling for discretionary trips to avoid the cost ofowning and
operating a private vehicle for a short term.

Site Location ond Layout - The location of the site, about 7+ mile from Meadow Drive in
the heart of Vail Village, will b€ convenient for walking or biking to many of the Town's
job locations, eateries, convenience shops and recreation opportunities. The site layout,
with a strong street orientation and parking tucked behind the units, follows the tenants of
Transit Oriented Development (TOD). Residents choosing to walk or use public transit
will have access to a planned bike /ped trail and a bus stop literally "outside their front
doo/'as depicted on your site plan. The Town of Vail's public transit system is one of
the most heavily used in the State of Colorado. From our experience at a number of
resort communities throughout the western US, Vail is the standard which other transit
systems strive to emulate. Residents and visitors will have access to Avon, Beaver Creek
and downvalley via ECO Transit (Eagle County) express buses connecting at the Town's
transportation center - about a lGminute walk and in-Town shuttle trip from the site. Car
drivers, on the other hand, will park in a lot behind the building complex, driving around
the complex to access North Frontage Road. This configuration is the equivalent, on a
single family neighborhood scale, of alley parking and front yard porches. The message
that the automobile is of lesser importance in site design choices is clearly conveyed.
We expect the access, convenience and economics of altemative modes for the seasonal residents
of Middle Creek Village will yield a vehicle trip reduction of 30 to 35 % from the "6pical" as
determined by standard trip generation references. lnstead ofthe 1,400 daily vehicle trips that a
200-unit apartment complex could generate in a typical suburban setting, we estimate trip
generation for this pdect will be in the order of 950 trips per day.
Site Access and Circulation
The site will have two North Frontage Road access points as shown on your site plan. The west
access is the existing road to the Mountain Bell tower. This drive will be used by residents
parking in the small lot near the frontage road at the west end of the site and by those driving
west ofthe project. The east drive will be convenient for day care trips and others driving
through the main Vail I-70 interchange.
North Frontage Road is located within the I-70 right of way and is under the administrative
jurisdiction of the Colorado Department of Transportation. In accord with the State Highway
Access Cde, eachdrive will need formal access permitting. The existing west access will need
a repermitting since there will be a change in use of the access. The east drive will need an
access application zubmitted and approved by CDOT Region 3 in Grand Junction. CDOT
usually requests local concurrence before issuing a new permit. We can work with your civil
design firm (Peak Land Consultants) to prepare the necessary application documents at the
appropriate phase of your design development process. CDOT has a maximum of 45 days from
the time a complete application is submitted to render their decision.
From our discussions with Jim Ellerbroek ofPeak Land, there does not appear to be any sight
limitations along the section ofNorth Frontage Road. Location of the east drive should consider
right turn deceleration in a zone where vehicles coming out ofthe roundabout will be
accelerating up to the 35-mph posted speed. At a minimum the east drive should be stopping
sight distance from the roundabout which for 35 mph is 250 feet (wet pavement). CDOT may
Lee Muon
St?3nl
Page 3
require a right hrm deceleration lane or just a right turn taper for the east access. Acceleration
lanes are typically not required when the posted speed is below 40 mph.
We trust this initial traffrc review will assist you with your upcoming project discussions with
Town staff We look forwardto working with you, if needed, on futuretraffic irnpact analysis
for the Middle Creek housing development.
Please call me if you have any questions on this review.

Preliminary Drainage Report
For
Middle Creek Villaee
Town of Vail, Eagle County, Colorado

Introduction
The Nfiddle Creek Village site is a parcel of land in the Town of Vail, located in the
Southeast % of Section 6, Township 5 Soutb Range 80 West. The site is north of the
north frontage road of I-70 approximately % mile west ofthe main Vail interchange. The
attached vicinity map shows the project location. The existing site proposed for
development is approximately 8.1 acres and includes the existing Mountain Bell Road
and the Qwest (old Mountain Bell) microwave tower building. The proposed
development plan consists of 8 multi-unit buildings with related parking and appurtenant
structures. Mountain Bell Road would be extended through the site to create a loop to
and from the north frontage road.
Existins Hvdrolosv
Mddle Creek passes through the property from north to south approximately 250 feet
west of the existing Mountain Bell Tower building. The Ilfiddle Creek drainage basin is
approximately 6 square miles and is included nthe Flood Insurance Study of the Town
of Vail dated November 2,1982. The hydrology of the drainage basin will remain
largelyunchanged as a result ofthe proposed development. The 100 year floodplain
based on stream depth, as shown on flood profile panels 07P thru 09P, has been
delineated and is included in the appendix.
The westerly 1/3 of the proposed development site (Z.A acres) is within the Middle Creek
drainage basin. The existing Mountain Bell Tower building, parking lot and driveway to
the north frontage road occupies 0.9 acres ofthe proposed development site.
The easterly 2/3 of the site (5.3 acres) flows south to the roadside ditch along the north
frontage road which flows east toward Spraddle Creek.
All hydrology calculations in this study utilized the Rational Method. This method has
been shown to be appropriate for calculating the hydrology of small drainage basins of
fewer than 100 acres. Runoffcoefficients were taken from the Urban Drainage Manual,
Denver Regional Council of Governments, Table 3-I , and rainfall intensities were taken
from the Taw of Vail "Intensity - Duration - Frequency Curves". The table and curves
are presented in the Appendix.
Pronosed Hvdrologv
The development of the existing site will utilize the existing drainage basins with 1/3 of
the site draining to Middle Creek and 2/3 of the site draining to the north I-70 frontage
road ditch. Approximately 9.4 acres of offsite drainage flowing through the site are
included h the rational method calculations. Proposed drainage patterns through the site
will approximate the existing conditions. No detention is proposed for the site. The
sunrmary table presents the results of the study with hydrology calculations shown in the
appendix.
Water Oualitv Issues
Proposed inlet design will include additional depth in accordance with rown of Vail
standards to facilitate sedimentation. Proposed sedimentation pond at the southeast
corner of the project site will also act to promote sedimentation and infiltration of runoff
from the site. All swales will be grass lined or lined with rip-rap when water velocities
and slope mandate. Additionally, silt fence and straw bale dikes will be used throughout
the site during the construction process.
Proposed drainage improvements include extension of the existing Middle Creek culvert
to the nortlg catch basins in Mountain Bell road at both the southwest entrance and the
southeast entrance to the site, and culverts under the Mountain Bell road enrrances to
accommodate the north frontage road drainage. Hydraulic calculations for the drainage
improvements are included in the appendix.
Conclusions
Runofffrom the proposed development will follow existing drainage patterns. The
proposed sedimentation basin will serve as a water quality feature io pro-ote
sedimentation and infiltration. catch basins wifi have additional depth to further
facilitate sedimentation. Inlets, catch basins and culverts will be designed to safely pass
the l0-year event. Sur ce drainage improvements will be designed to safely pusj tLe
100-year event without damage to property. As the site plan ii refined, thii drainage
study will need to be updated.
