MEMORAPlDUM
T0: County Planning and Zoning Commission
FROM: .Jim Reents, Planning Off ice
RE: The First Emma Venture
DATE• August 14, 197°
The applicant is requesting a 1041 Review of geologic hazard, wildfire hazard, wildlife
winter range, and snow avalanche potential for permission to build. asingle-family res-
idence on a parcel of approximately 48 acres.
This application has been referred to the. referral agencies, but no comments have been
received.
The applicant had a site analysis done by Nick Lampiris, Consulting Geologist, and he
recommends development on the flat. portion to the top of the property and identifies that
as being free of geologic hazard. This building envelope is identified in the accompanying
map.
Access would be provided by an existing road. that; by Lampiris' recommendation, should be
widened in several spots.
The Planning Office recommends approval of development of this site with the following con-
ditions• ~
1. Approval of a sanitation system by the County Sanitarian.
2. Approval by'the State Division of Wildlife for any fences to be constructed. or 1
a requirement tha~ all dogs be fenced or kennelled. '
.~ 3. The requirement that there be fuel modifications to insure no wildFire hazard area
in' the immediate vicinity of the stucture:,

DATE. June J.9, 1979 -
The applicant requests that a permit be issued for
the development of a single family residence ort a`parcel of
-land of approximately 48 acres in size. According to CSU
mapping, the following hazards affect certain portions of
this property:
a) Geologic hazards;
b) .Wildfire hazardst
c) wiidlife winter range;
d) Snow avalanche potential.
In order to mitigate these hazards the applicant proposes
to build the dwelling unit on a flat portion of the property
located at the top of the 48 acre parcel. An existing access

road serves this area•and a map is inc~.uded with this applica-
tion indicating a proposed building envelope which is several !~
hundred feet in dameter_so that the house maybe sited in the
best possible manner to avoid hazards.
A report is attached from Nicholas Lampirs, geologic
consultant, which describes the property and indicates good
access, suitable soils for septic, no :avalanche hazard. being
.present, no geologic hazards present, and sparse vegetation.
The report recommends that the buildinq be located in the
.area indicated. on the attached map as "building envelope".
The sparse vegetation on this part of the site mitigates the
wildfire hazard and the remainder of the .property not part
• of the building envelope contains most of the other hazard
areas. '
Under the land use code, the applicant is entitled by ~ `
}
right to construct this dwelling with the only requirement
other than building. permit review being a'reasonable mitigation
and consideration of T041 hazards. The applicant is flexible
insofar as precise location of the dwelling within the building
envelope and therefore will. site the ertructure to accommodate
i
recommendaticns of the Planning Office, County Boards and
referral agencies. The Division of Wildlife should be consulted'
for its recosmendaton concerning any interference with wildlir`e,
in the area due to the erection of the""proposed structure. ` ';

RE: Rudolph 1041 Special Review
Dedr Mr. Reents,
This proposal would ,be of concern from a wildfire hazard viewpoint if more than
one dwellino is'planned. Since only one dwelling is planned and the building site
was chosen after considering fuels and'slopes; the wildfire hazard has been consider-
ably mitigated, The~applicant'should be cautioned to'maintain a fuelbreak four to
five times as `wide as the structure is high around the structure, particularly on I
the downhill side. Additionally, by avoiding unenclosed cantelevered decks and long
overhanging roof eaves in the structure's design, as well as a wood shingled roof,
the wildfire hazard wi11 6e further mitigated.
Thank you for the opportunity to re5iew this proposal:

RE: Geological Report, First Emma Venture Property
Dear Herb:
I have completed,my geologic investigation of the First
Emma Venture Property for which a slope analysis was done in
September, 1978. The shaded areas on the accompahying sketch
map include all acreages with slopes less than 45% in steepness.
It is the large flat area in the eastern half of the property
that this report will concentrate on as it is the most develop-
able portion of the lot.
The property is located in the West half of Section 24
and the East half of Section 23, Township 8 South, Range 87 ~
appaoximately1onenmilepandMOneohalfwduehsopthpoftthesoldcEmmanute
towns>_te. It is more specifically in the divide between fast
and West Sopris Creeks. The irregularly shaped tract 'consists
of very few trees but much brush, grasses and wildflowers.
The northwest and northeast slopes of the property are relatively'
steep with erosion being rather active on the northeast slope.
The access road approaches from the southwest along the northwest'-
facing slope. This access appears quite suitable with a gentle
grade and no severe turns; however, two 20 yard long portions
of this access road will have to be widened about 5 feet as
sloughing from the steep uphill portion of the cut has made
narrow sections. From the relatively flat top portion of the
lot slopes dip rather gently to the southeast and southwest.
There are_ho perennial or intermittent streams `on this develop-
able portion of the property.
The geology of the property consists basically of colluvial
material overlying Triassic age Chinle Formation which dips
gently to the south at approximately 20°. The Chinle Formation
is comprised of rather erodible red hematite-cemented shales
and mudstones. The colluvial material is well exposed alonq
the road cut in the access road approaching from the wesf.
It consists of weathered Chinle Formation and loose blocks
of buff-colored sandstone mixed in with silts, sands, and rounded
boulders which seem to have been deposited by a higher level
.~F
~ ` ,
~~ Herbert S. Klein, Esq.

of one of the Sopris Creeks. This colluvial material forms
a U-shaped pattern around the northeast and northwest portions
of the property, but not quite reaching the, top, flat developable
portion. No faults or rockfall hazard or landslides have been
noticed or mapped in the vicinity of the property, although
some of the steep slopes in this vicinity do show signs of
downslope creep. For this reason I recommend that any building
construction be restricted to the flat portions of the east
half of the lot preferably in the southern half of this flat
as designated on the accompanying sketch map. This building
envelope as shown provides for a 50 ft, setback from adjoining
steeper slopes. Soils derived from the Chnle Formation are
generally not susceptible to swelling or other problem situations;
however, soils engineering studies should be conducted prior
to foundation design. No avalanche hazards are present.
The soils of the building envelope will have a significant
percentage of clay in them so that percolation rates may be
slow. The County Sanitarian should be consulted for his
specific recommendations for waste disposal through leachfields;
however, it is my 'opinion that the percolation rates in the
soils will be suitable for waste disposal in this manner.
Water for domestio use will have to be obtained through
the drilling of a well. A permit has been obtained for a well
to be drilled in the northwestern portion of the property near
stream level with a depth to be anticipated somewhat in excess
of 100 ft. and the ensuing water pumped up the hill to the
southeast. to the building site. The probability of securing
water is high. I recommend a holding tank of one to two
thousand gallon capacity near the building site to provide
water during slack periods.
Based upon the above considerations it is my opinion
that the flat area at the top of the property as designated is the
best location for development as it is free of geologic hazards.
If there are further questions please do not hesitate to contact me.
