Attn: Nancy McKenzie
Dear Nancy:
Thursday, August 13, 1998
The following is the soil information for the Towning Residence, caretakers addition, located at 173
Buchanan Drive within the Starwood Subdivision in Aspen, Colorado.
A soil profile 8'— 9" total depth, was excavated within the proposed absorption area. The excavation
revealed no ground water to the depth of the profile hole.
Soil Classification of the profile hole is as follows:
0" to 42" Top Soil and Root Zone
42" to 75" Maroon formation talus cobbles in clay soils
75" to 105" Tan colored clay, some weathered granite cobbles, Maroon formation cobbles
Jerome Gamba & Associates, Inc. performed percolation testing in the area of the proposed
caretakers unit septic system. Three percolation test holes (53", 45" and 36" depths) were excavated
using a backhoe and hand shovel for the final 12" test pit.. The Test holes were presoaked the night
before the testing was performed.
The results of the percolation testing are presented below in Attachment 1. These results indicate an
average percolation rate of 160 min/in.

Percolation Testing Results
This report has been prepared according to generally accepted engineering practices for the design
of Individual Septic Disposal Systems within Pitkin County. The conclusions and recommendations
submitted in this report are based upon data obtained from our field investigations of the proposed
site. There is some possibility that the nature and extent of the subsurface soil across the site may
not have been discovered during our investigations and may require additional field work. If further
excavation reveals conditions different form those described, our office should be notified of these
findings as soon as possible.
If you have any further questions regarding this soil investigation please call us.
Sincerely,
Jerome Gamba & Associates, Inc.

Nancy,
Here is the proposed system for the Towning residence as I had tried to explain to you over the phone. It
probably makes some sense now, I hope. Atleast you can see the general layout. The 2500 gal. overflow tank
location is going to be located in the most accessable location to be pumped and not impact the Townings if it
needs to be pumped.
Also with this is the information on the F.A.S.T. system and a study about treated effluent in the rehabilitation of
failing septic systems.
call me if you have any further questions.

Re: Towning Caretaker Dwelling Unit
Parcel ID # 2643-264-02-010
The Aspen/Pitkin Environmental Health Department has reviewed the details of the Towning
application under the authority of the Pitkin County Land Use Code and has the following
comments.
ADEQUATE PROVISIONS FOR WATER NEEDS: Sections 2-17 and 3-1104:
"It is the policy of the County to insure the availability of a water supply of adequate quality, quantity, pressure and dependability for fire
protection and support of a proposed land use prior to approval of the use. The County shall require land uses to hook up to existing public
systems if service is available."
This house is served with water provided by the Starwood Water District and the applicant has
not provided a "...letter of intent to service the proposal..." as defined in the Pitkin County Code.
A condition of approval for this application is the receipt of a letter of intent to serve the
caretaker unit from the Starwood Water District. Without meeting this requirement a
septic permit and building permit can not be issued.
SEWAGE TREATMENT AND COLLECTION: Sections 2-18 and 3 -1105:, -it is the policy of the County to
ensure that adequate sewage treatment facilities are available to serve existing and new developments. Public and private sewage disposal systems
and connections to such systems shall comply with the sewage disposal guidelines of Pitkin County's Individual Sewage Disposal System
Regulation."
Lots in the Starwood area are served by individual septic systems. The new system installed
under ISDS permit # 97040 was designed for 5 bedrooms and is not sized to handle the effluent
flow from the proposed caretaker unit.
Jack Miller , who is the owners' representative for this application, has been contacted and is aware
that the ISDS will have to be enlarged to handle this added use and that the system must comply
with the County's current septic regulations. The addition of this attached caretaker unit will bring
Printed on Recycled paper 1
the house's total size over 6,000 sq ft and add a bedroom We have estimated that about 98 units of
infiltrator will have to be added to the absorption field and a 1,000 gallon septic tank will need to
be added. The original system was designed by Jerome Gamba & Associates and they should be
consulted directly for their recommendation.
A condition of approval for this application is the receipt and approval of the septic
permit by the Environmental Health Department before a building permit can be issued.
WATER QUALITY IMPACTS: Sections 2-14 and 3-705 and 3-710:
"It is the policy of the County to preserve and protect its present water resources. To this end it is the policy of the County that no land use be
initiated which would adversely affect the quantity, quality, or accessibility of the County's water resources; or which would occur at the expense
of established water -dependent agricultural activities; or which would result in increased salinization of water resources, loss of minimum stream
flows, further destruction of wildlife habitat, or major expenditures to reacquire or redistribute major water resources. It is also the policy of the
County to maintain a natural vegetative buffer along its surface waters such that the surface and groundwaters of the area are not encroached upon
by land uses or other human activities which could cause deterioration of water quality or, impair the natural treatment processes provided by
meadows and wetlands."
The Environmental Health Department will be addressing water quality impacts on down stream
water quality. This application is not expected to impact down stream water quality if the
minimum horizontal distances between components of the system and physical features are in
accordance with the Pitkin County Sewage Regulations.
A condition of approval for this application is: None
AIR UALITY: Sections 2-13 and 3-602_
"Only that development is permitted which will not contribute significantly to degradation of air quality in Pitkin County. Developments may not
constitute an indirect or direct air pollution source under Federal, State or County regulations."
This project is not expected to contribute significantly to degradation of air quality in Pitkin
County.
FIREPLACE
If there will be a fireplace in the caretaker unit the applicant must file a fireplace/woodstove
permit with the Environmental Health Department before the building permit will be issued. Since
this house has two existing woodburning fireplaces, only gas fireplace appliances may be installed.
A condition of approval for this application is the receipt and approval of the
fireplace/woodstove permit by the Environmental Health Department before the
building permit can be issued.

CONFORMANCE WITH OTHER ENVIRONMENTAL HEALTH LAWS: Section 2-7: "It is the policy of
the County to ensure that no use or development of land is permitted which is in violation of the laws of the County, the State of Colorado, or the
United States of America."
This Department is not aware of any issues of concern regarding other environmental health laws.
