Re: Aspen Village Subdivision, Rezoning, Major Plat Amendment, 1041
Hazard Review, GMQS Exemption, CDU &EDU
Parcel ID #2643-064-00-019 (, F
The Aspen/ Pitkin Environmental Health Department has reviewed the details of the
Aspen Village application under the authority of the Pitkin County Land Use Code and
has the following comments.
In general, the proposed application will reduce the number of developable living units
on this parcel from that previously approved, and this project will have far less impact
on water quality and air quality than what had been allowed. A 14 unit platted
subdivision on 28.8 acres has been replaced by a ranch parcel with a ranch manager
unit and ranch outbuildings, and 43 unit townhouses on 4 acres have been eliminated.
A single family homesite with a caretaker unit on a 554 acre parcel has been added.
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."
The Aspen Village Mobile Home Park is serviced by two wells. The quality of the
drinking water is monitored by the Colorado Department of Public Health and
Environment on a monthly basis. This Department has not been notified of any unsafe
levels of bacteria.
During an annual inspection of the Water Treatment Facilities, a letter dated October 24,
1991 (attached) noted items that needed attention.: an inverted " U" vent repaired and a

concrete pad repaired. BEFORE final approval, it needs to be established that these
repairs have been made.
The wells are not located in any of the parcels discussed in this application. The wells
are located across Hwy 82 down slope from the sewage lagoons. A condition of
approval for this application is that prior to recording of the final Plat, the applicant
shall file and record conveyance to the Homeowner's Association the ownership of the
wells, water rights, all of the pipeline and equipment, and adequate easements for the
maintenance and operation of the system. A plat of this shall be provided to the
Aspen/ Pitkin Environmental Health Department which includes showing the
relationship of the wells to the sewage lagoon.
Section I - Page 22 states that an upgraded water system for the park is currently
under construction. There is no further documentation provided to substantiate this
claim and this Department has no knowledge of this construction. This Department
needs copies of any state permits for the new system.
With regards to Parcel A & B, whenever a mobile/manufactured home is replaced or
remodeled, the lot owner will be required to provide a letter to the Aspen/Pitkin
Environmental Health Department from the Homeowners Association stating that they
have adequate water capacity to meet any increased demands.
The application states that the Ranch manager unit will use either the existing water
system serving the mobilehome park or will have its own well. Any additional use of
the existing water system will require that the Association provide this department
with a letter stating that they have adequate water to meet any increased demands.
The application addresses concerns for the location of the single family homesite. Low
well yield in this area is a concern. A storage tank may be required to assure adequate
water quantity to the dwelling. This Department will need adequate information on the
quantity and the quality of water available. This can be done from tests of wells present
on-site by a water engineer's or well driller's report. The applicant must ensure that the
water quality is acceptable by having it tested by a lab such as the Snowmass Water and
Sanitation District or Aspen Consolidated Sanitation District. Before a sewage disposal
permit can be issued, the well must be drilled to assure that setback requirements from
the well to the sewage disposal system can be maintained. Pitkin County Land Use
Code requires that the well site be within the building envelope. The possibility exists
that to get a well with adequate yield, the well may need to located outside of the
building envelope.

A condition of approval is that this Department be provided copies of any
state permits for the new water system.
BEFORE final approval, it needs to be established that repairs to the wells
(inverted "U" vent and concrete pad) have been made.
A condition of approval for this application is that prior to recording of the
final Plat, the applicant shall file and record conveyance to the Homeowner's
Association the ownership of the wells, water rights, all of the pipeline and
equipment and adequate easements for the maintenance and operation of the
system. A plat of this shall be provided to Aspen/Pitkin Environmental
Health Department which includes showing the relationship of the wells to
the sewage lagoon.
A condition of approval for this application is the receipt of information
documenting that the location of the new well(s) meet setback requirements
and can be placed within the building envelope and that quantity/quality of
the well water are adequate. Without meeting these requirements a sewage
disposal 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.'
Section 1- Page 22 states that an upgraded sewer system for the park is currently under
construction, but no further documentation is provided to substantiate this claim and
this Department has no knowledge of any upgrade being done. This Department needs
copies of any state permits for the new system
The waste water treatment plant for the mobile homes and the gas station is operating
under a Colorado Wastewater Discharge Permit effective through September 30, 1998
The Colorado Department of Health has stated several concerns in their Annual
Inspection letter dated April 21,1995 (attached). A condition by this Department is
that the noted items come into compliance before final approval.
1. Correct Discharge Permit to reflect legal contact and current owner
2. Lift station does not meet the Department's Design Criteria for safety and reliability
3. The flow measuring equipment needs to be calibrated.

Since the flow meter determines if the ponds are leaking, it needs to be established that
the ponds are not leaking, or if they are leaking, this must be corrected, BEFORE final
Renewal of this discharge to surface water permit should be started. Because the
existing sewage lagoons have no liner, to be in compliance with the new federal water
quality laws ,the Homeowner Association will need to begin the application process for
a permit to discharge to groundwater. The Homeowners Association should be aware
of the future high costs of this type of permit which requires monitoring wells, another
permit fee and routine sampling fees. It is possible that a minimum of 4 monitoring
wells would be required. There would be the initial cost of drilling these monitoring
wells and then monthly sampling fees of possibly $400/ mo ($100 per well). An option
would be to line the sewage lagoons, also costly, but a one time cost which over the
long term might be more cost effective.
With regards to Parcel A & B, whenever a mobile/manufactured home or the
commercial facilities is expanded, the owner will be required to provide a letter to the
Aspen/Pitkin Environmental Health Department from the Homeowners Association
stating that they have adequate sewage disposal system capacity to meet any increased
If the Ranch manager unit wants to use the waste water treatment plant, the lot owner
will be required to provide a letter to the Aspen/ Pitkin Environmental Health
Department from the Homeowners Association stating that they have adequate
capacity to meet any increased demands.
The single family residence and possibly the Ranch manager unit will be served by
individual sewage disposal systems. All such systems installed within Pitkin County
require permits issued by the Environmental Health Department, and must comply
with the Pitkin County Individual Sewage Disposal System Regulations. To receive a
permit, the applicant will need to submit an application and appropriate fee with a
completed Soil Data Form including percolation test results and profile hole
information. It must be possible to design an adequate sewage disposal system before a
building permit can be issued.
The Aspen/Pitkin Environmental Health Department will design the system for the
applicant as part of the permit fee, if an engineered system is not required. We will
do a site visit, advise the applicant about the best location for the system and provide a
system design. We will determine if an engineered system is needed based on soil test
results. An engineered system is required ifiany one of the following conditions occurs:
a percolation rate faster than 5 mpi or slower than 60 mpi; maximum seasonal level of
the groundwater table or bedrock less than four feet below the bottom of the proposed
absorption system; or a slope in excess of 30°x. Prior to initiating any tests at the site,
the applicant should contact this office.
Based on the data in the geological and engineering reports submitted with the
application it is likely that an engineered sewage disposal system for the main residence
will be required. The building envelope appears large enough to accommodate a
sewage disposal system.
Most well permits state that the sewage disposal system must be of the non-
evaporative type where the water is returned to the same stream system in which the
well is located. This means that a completely lined field, such as an evapo-transpiration
bed, is not allowed unless the applicant contacts the Colorado Division of Water
Resources and a new well permit is in place or a plan of augmentation is created.
A condition by this Department is that the noted items come into compliance
BEFORE final approval:
1. Correct Discharge Permit to reflect legal contact and current owner.
2. The Lift station does not meet the Colorado Department of Public
Health and Environment Design Criteria for safety and reliability.
3. The flow measuring equipment needs to be calibrated.
A condition by this Department is that it must be established that the ponds
are not leaking, or if they are leaking, this must be corrected, BEFORE final
approval.
A condition of approval is that the renewal process of the Discharge to Surface
Water Permit be started.
A condition of approval for this application is the receipt and approval of the
Individucal Sewage Disposal System permit by the Environmental Health
Department before a building permit can be issued.
WATER OUALTTY 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' urface and groundwaters of the area are not encroached upon by land uses or other human activities which
could cause de%rioration of water quality or impar 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 and
Rules and Regulations of the Colorado Department of Public Health and Environment.
A condition of approval for this application is: NONE
AIR OUALITY: Sections 2-13 and 3-602:
"Only that development is permitted which will not contribute siguficantly to degradation of air quality in Pitldn 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, in fact this application, which reduces the number of developable living
units, will have far less impact on air quality than what had been allowed.
Activities such as road building and landscaping may require a Fugitive Dust Plan. This
plan would need to include, but is not limited to, fencing, watering of haul roads and
disturbed areas, daily cleaning of adjacent paved roads to remove mud that has been
carried out, speed limits, or other measures necessary to prevent windblown dust from
crossing the property line or causing a nuisance.
The applicant must file a fireplace/woodstove permit with the Environmental Health
Department before a building permit will be issued. The less densely populated parts
of the county like Watson Divide may have two devices per building: a maximum of
one wood burning fireplace and a second device which can be either a gas log fireplace
or a certified woodstove. In addition, unlimited numbers of decorative gas appliances
are allowed. Coal may not be burned in any device. No wood burning device may be
installed in barns or agricultural buildings.
Any remodeling that affects the firebox of a fireplace will necessitate that the device
meet current regulations.
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.
