RE: Special Use Review
Lot 6, Filing 5
Aspen Glen Sub'd.
Mark,
This letter is being written requesting a special use permit for construction of a single
family residence. The proposed construction will take place within a previously
approved plat that has a building envelope within the flood plain fringe.
We are requesting the special use permit as required by the approved plat pertaining to
this portion of the Aspen Glen Subdivision. The entire building envelope occurs within
the 'flood plain fringe' which will require us to bring in fill to achieve the minimum one
foot clearance from the lowest floor to the highest `,fringe' contour. This site has been
approved for a single family residence and we are asking for the ability to continue with
the construction document phase for the project.
The proposed development (single family residence) has been submitted and
preliminarily approved by the Aspen Glen Design Review Committee. Final submission
and approval is pending the Special Use Review.
The Zoning Regulations have all been met by the previously submitted platting of the
Aspen Glen Subdivision. Therefore, Section 8 of the Application Submittal
Requirements have been previously addressed and met.
Respectfully submitted,

PURPOSE AND SCOPE OF STUDY
This report presents the results of a subsoil study for a proposed residence to be located
on Lot 6, Riverglen, Aspen Glen, Garfield County, Colorado. The project site is shown
on Figure 1. The purpose of the study was to develop recommendations for the
foundation design. The study was conducted in accordance with our agreement for
geotechnical engineering services to Jordan Architecture dated .lanuary 25, 2005.
A field exploration program consisting of -exploratory borings was conducted to obtain
information on the subsurface conditions. Samples of the subsoils obtained during the
field exploration were tested in the laboratory to determine their classification.
compressibility or swell and other engineering characteristics. The results of the field
exploration and laboratory testing were analyzed to develop recommendations for
foundation types, depths and allowable pressures for the proposed building foundation.
']'his report smurnarizes the data obtained during this study and presents our conclusions,
design recommendations and other geotechnical engineering considerations based on the
proposed construction and the subsurface conditions encountered.
PROPOSED CONSTRUCTION
P.04/16
The proposed residence will he a two story, wood frame structure with an attached garage
located on the lot as shown on Figure 1. Ground floor will be slab -on -grade. Grading
will involve filling the site to raise the structure to above the flood plain level shown on
l figure I. We assume relatively light foundation loadings, typical of the proposed type of
construction.
ii.'building loadings, location or grading plans change significantly from those described
above, we should he notified to re-evaluate the reconunendations contained in this report.

SITE CONDITIONS
The lot is located at the north end of the Riverglen cul-de-sac and was vacant at the time
of our field exploration_ The Roaring Fork River borders the site to the northeast. Fill
from roadway construction is located at the south side of the lot and the building area is
roughly 6 feet lower in elevation than the cul-de-sac. The building envelope is located on
a relatively flat topographic bench about 4 to 5 feet in elevation above the Roaring, Fork
River and the site slopes gently down towards the river. Vegetation consists of grass with
scattered willow trees. Several rounded cobbles were visible on the ground surface.
SUBSIDENCE POTENTIAL
Bedrock of the Pennsylvanian age Eagle Valley Evaporite underlies the Aspen Glen
development. These rocks are a sequence of gypsil'erous shale, fine -brained sandstone
and siltstone with some massive beds of gypsum and limestone. There is a possibility
that massive gypsum deposits associated with the Eagle Valley Evaporite underlie
portions of the lot. Dissolution of the gypsum under certain conditions can cause
sinkholes to develop and can produce areas of localized subsidence. During previous
gcoleclinical investigations for the subdivision development, several sinkholes were
observed scattered throughout mainly areas east of the Roaring Fork River. These
sinkholes appear similar to others associated with the Eagle Valley Evaporite in areas of
the Roaring Fork River valley.
P.05/16
Sinkholes were not observed in the inunediate area of the subject lot. No evidence of
cavities was encountered in the subsurface materials; however, the exploratory borings
were relatively shallow, for foundation design only. Based on our present knowledge of
the subsurface conditions at the site, it cannot he said for certain that sinkholes will not
develop. The risk of .future ground subsidence on Lot 6 throughout the service life of the
proposed residence, in our opinion, is low; however, the owner should be aware of the
potential sinkhole risk. if further investigation of possible cavities in the bedrock below
the site is desired, we should be contacted.

Samples of the subsoils were taken with 13A inch and 2 inch 1.1). spoon samplers. The
1 samplers were driven into the subsoils at various depths with blows from a le -i0 pound
I hammer falling 30 inches. This test is similar to the standard penetration lest described
by ASTM Method D-1586. The penetration resistance values arc an indication of the
relative density or consistency of the subsoils. Depths at which the samples were taken
Iand the penetration resistance values are shown on the Logs of Exploratory Borings,

1 SUBSURFACE CONDITIONS
I
Graphic logs of the subsurface conditions encountered at the site are shown on Figure 2.
The subsoils generally consist of between 1/2 to 1 foot of topsoil overlying relatively
'dense, silty sandy gravel with cobbles and boulders (alluvium) down to the maximum
explored depth of 101/2 feet at Boring 1. A silty sand and clay layer. approximately 21/
sect thick, was encountered between the topsoil and gravel at Boring 2. Drilling in the
1 dense gravel alluvium with auger equipment was difficult due to the cobbles and boulders

Laboratory testing performed on samples obtained from the borings included natural
moisture content, density and gradation analyses. Results of swell -consolidation testing
performed on a relatively undisturbed drive sample of silty sandy clay. presented on
Figure 4, indicate relatively high compressibility under conditions of loading and wetting.
Results of gradation analyses performed on a small diameter drive sample (minas I'/2 inch
fraction) of the coarse granular subsoils are shown on Figure 5. The laboratory testing is
suminanzcd in Table 1.
Free water was encountered in the borings at depths of 5 to 5'/2 feet below the ground
surface. The subsoils above the groundwater level were moist to very moist.
DESIGN RECOMMENDATIONS
FOUNDATIONS
S
P.07/16
Considering the subsurface conditions encountered in the exploratory borings and the
nature of the proposed construction, we recommend the building be founded with spread
footings bearing on the natural granular soils or compacted structural fill.
Th: design and construction criteria presented below should be observed for i spread
footing foundation system.
1) Footings placed on the undisturbed natural granular soils or compacted
structural fill should he designed for an allowable bearing pressure of
2,000 psf. Based on experience, we expect settlement of footings designed
and constructed as discussed in this section will be about 1 inch or less.
2) The l otings should have a minimum width of 16 inches fir continuous
walls and 2 feet for isolated pads.
3) Exterior footings and footings beneath unheated areas should be provided
with adequate soil cover above their hearing elevation for frost protection.
Placement of foundations at least 36 inches below exterior grade is
typically used in this area.

1 • 4) Continuous foundation walls should be reinforced top and bottom to span
local anomalies such as by assuming an unsupported length or at least 12
feet, Foundation walls acting as retaining structures, if any, should also he
designed to resist a lateral earth pressure corresponding to an equivalent
fluid unit weight of at least 45 pcf for predominantly granular soils As
hack fill.
5) Structural fill placed below the footing bearing level should consist of a
suitable granular material, such as pit run, compacted to at least 1 00% of
1 the maximum standard Proctor density at a moisture content near
optimum. The fill should extend out frost the footing edges a horizontal
1 distance greater than or equal to the depth of fill below the footing, hut at
least 3 feet. Prior to fill placement, the subgrade should be prepared by
1 removing the vegetation, topsoil and clayey soils, adjusting the moisture
content to near optimum and cornpa.cting to at least 95% of the maximum
standard Proctor density.
' 6) A representative of the geotechnical engineer should observe and evaluate
the fill placement and compaction for compliance with the design
'recommendations, and observe ail looting excavations prior to concrete
placement to evaluate bearing conditions.
FI ,00R. SLABS
Compacted structural lill and the natural granular soils below the topsoil and clayey soils
are suitable to support lightly loaded slab -on -grade construction. To reduce the effects of
some differential movernent, non-structural floor slabs should be separated from all
bearing walls and columns with expansion_ joints which allow unrestrained vertical
movement. Floor slab control joints should be used to reduce damage due to shrinkage
cracking. "fhe requirements for joint spacing and slab reinkirceinent should he
established by the designer based on experience and the intended slab use. A minimum
4 -inch layer of sand and gravel should be placed beneath interior slabs for subgradc

pavement and slab areas and to at least 90% of the maximum standard
Proctor density in landscape areas.
The ground surface surrounding the exterior of the building should he
sloped to drain away from the foundation in all direction. We
' recommend a minimum slope of 6 inches in the first 10 feet in. unpaved
areas and a minimum slope of 3 inches in the first 10 feet in paved areas.
4) Roof downspouts and drains should discharge well beyond the limits of all
backfill.
' LIMITATIONS
This study has been conducted in accordance with generally accepted geotechnical
engineering principles and practices in this area at this time. We make no warranty either
express or implied. Tlie conclusions and recommendations submitted in this report are
based upon the data obtained from the exploratory borings drilled at the locations
indicated on Figure 1, the proposed type of construction and our experience in the area.

Our services do not include determining the presence. prevention or possibility of mold or
other biological contaminants (MOBC) developing in the future. If the client is
concerned about M(_)BC, then a professional in this special field of practice should he
consulted. Our findings include interpolation and extrapolation of the suhsurfttce
conditions identified at the exploratory borings and variations in the subsurface
conditions may not become evident until excavation is performed. 1f conditions
encountered during construction appear different fi-om those described in this .report, we
should be notified so that re-evaluation of the recommendations may be made..
This report has been prepared for the exclusive use by our client for design purposes. We
are not responsible for technical interpretations by others of our information. A.s the
project evolves, we should provide continued consultation and field services during
construction to review and monitor the implementation of our recotnmendatio2ns, and to
verily that the recommendations have been appropriately interpreted. Significant design
changes may require additional analysis or modifications to the recommendations
presented herein. We recommend on-site observation of excavations and foundation
bearing strata and testing of structural fill by a representative oFthe geotechnical
engineer.

Re: Special Use Permit
Lot 6, Filing 5, Aspen Glen Sub'd.
Fred,
As requested, we are attempting to address the standards for our special use submission.
Per section 6.09.02, we will be protecting the Roaring Fork River along with our
site by installing temporary fencing in an attempt to prevent any and all debris, and any
other material from being carried downstream by floodwaters.
We will also be storing equipment and supplies on higher ground, above the 100
year flood line (6003). This will also be accomplished by bringing a substantial amount
of structural fill to meet the minimum requirement required by the special use permit.
Our final lowest level floor elevation will be no lower than 6004 (1 foot above the 100
year flood line), as required by the special use permit.
The foundation will be designed by a professional engineer to insure that the
structure is properly anchored to prevent flotation.
All sewage will be piped to the existing sewer mainline to insure that there is no
infiltration to floodwaters.
This particular site is not within the 'AO' zone and we will not be using a
manufactured home on this site.
A new survey is submitted with this letter better delineating the flood way and
designating an actual elevation of the 100 year flood line. The proposed residence will
have a lowest level finished elevation of 6004, which is 1 foot above the 100 year flood
line elevation.
Feel free to contact our office with any additional requested information.
Respectfull

In accordance with Section 404 of the Clean Water Act, a
Department of the Army permit is required prior to commencing any
discharge (including mechanized land clearing) of dredged or fill
material in waters of the United States. Waters of the United
States include the territorial seas; perennial, intermittent, and
ephemeral streams; lakes, ponds, impoundments; and wetlands. For
your convenience, I am enclosing a list of consultants that
perform wetland and other jurisdictional delineations and may
also assist with obtaining a permit from the Corps of Engineers.
For more information about the permit program, please visit our

WETLANDS DELINEATION CONSULTANTS -updated biannually
Increasingly, potential applicants for Department of the Army permits are hiring environmental
consultants to do wetlands determinations and delineations for them. In addition, because of Federal
budgetary and work force constraints, we are requesting that many potential applicants have wetlands
delineations done by consultants. Under existing constraints, the Corps of Engineers will field verify as
many wetlands delineations as possible. We recommend that wetlands delineations performed by consultants be
submitted for review and verification at least one month in advance of a submittal of a Department of the
Army permit application.
All wetlands delineations will be reviewed to insure compliance with the methodology contained in
the Corps of Engineers Wetlands Delineation Manual dated January 1987 and that sufficient information is
provided to justify the wetlands/upland boundaries as shown on the delineation map(s). To obtain a
jurisdictional determination letter from the Western Colorado Regulatory Office, all consultant -prepared
wetlands delineations shall contain:
1. A wetlands delineation map depicting a point-to-point survey of the wetlands boundary
as flagged by the consultant in the field. The consultant should review the survey for accuracy before
submittal to this office. We prefer topographic maps with contour intervals of one or two feet and at a
scale of 1 inch equals 100 feet. However, these specifications may vary depending upon the scope of the
delineation and the nature of the project. In certain situations, a point-to-point survey of the wetlands
boundary may not be required. However, the boundary must be reproducible in some manner. The consultant
should contact this office for approval before submitting a delineation without a point-to-point survey. In
all cases, the wetlands boundary must be marked with survey flagging or stakes in the field before this
office will conduct a site inspection to verify the delineation. The flags or stakes must be sequentially
numbered and those numbers shall appear on the survey for each point;
2. The type(s) of wetlands present, such as riparian willow, wet meadow, marsh, etc.,
should be shown on the delineation map. The respective sizes in acres of each type should be included
either on the map or in a report;
3. The location of all sample sites should be shown on the delineation map(s);
4. Wetlands delineation data forms, or similar data sheets, for each sample site, cross-
referenced to the sites should be shown on the delineation map(s). The data for each sample site shall
clearly list the indicators for the soils, vegetation and hydrology, and shall include the basis for
determining whether the sample site is wetlands or upland. The number of sample sites will vary depending
upon the size and shape of the wetlands, the degree of difficulty in differentiating wetlands and upland,
width of transition zones, etc.;
5. A site location map, preferably a 7.5 -minute USGS quadrangle, shall be included and any
other pertinent maps of the site; and
6. A brief written report shall be included with the submittal. This report should list
the property owner(s) and/or the developer(s) requesting the delineation. The report shall also describe
the nature of the proposed development, and when a permit application will be submitted for the project.
Your report should explain the basis for the wetlands boundary location and any problems or questionable
areas. The dates of the actual fieldwork should also be included in this narrative.
7. For potential isolated waters, including isolated wetlands, note in your delineation
report any observed and/or documented examples that substantiate the rationale for jurisdictional or non -
jurisdictional waters of the United States.
The Corps of Engineers will acknowledge wetlands delineations that are complete and accurate. In
the event that work force constraints preclude timely field verifications, this office may issue a qualified
approval. However, prior to definitive regulatory approvals, such as a letter of no Federal jurisdiction,
nationwide general permit verification, individual permit issuance, etc., wetlands maps will usually be
field verified by the Corps of Engineers.

We have attached a field data sheet for photocopying and field use. This form should be used for
wetlands delineations subject to Corps of Engineers verification. If you and/or your consultants have
questions regarding wetlands delineation procedures, please contact the U. S. Army, Corps of Engineers,
Sacramento District in Grand Junction, Colorado at telephone number (970) 243-1199.
The following list of wetlands delineation consultants is arranged alphabetically and should not be
interpreted as preferential. This list shall be accepted and used by the recipient with the explicit
understanding that the U. S. Government shall not be under any liability at all to any person because
of any use made of this list. The following are categor5es of a consultant's claimed unique expertise
and/or competencies:
Wetland delineationl, stream restoration and channel stabilization2, wetland mitigation3, fish
habitat improvement4, professional licensed engineering5, Section 404 & Section 10 violation
resolution/compliance6 and EA/EIS preparation7.
