Permitted Construction / Details:
Install the OWTS exactly as depicted in the JVA, Inc. design stamped, signed and dated March 26, 2020 by Kevin A.
Tone, PE. The OWTS is designed with capacity to serve three residences and a maximum of twelve bedrooms, four
bedrooms maximum in each residence.
The primary treatment for the system consists of a two Valley Precast 2,000 gallon, single compartment tanks (Item
#2000T-1CP) in series with an effluent screen and alarm placed at the outlet tee of the second tank. The primary
treatment tanks are followed by a 2,000 gallon Valley Precast three-compartment recirculating/dose tank which will
send wastewater to an Advantex AX 100 pod for nitrification using an Orenco PF 500712 pump. Nitrified effluent
flows to the splitter valve for recirculation to the first 2,000 gallon tank for denitrification then is dosed using an
Orenco PF 500512 pump to and automatic distribution valve (ADV), set level at the high point of the system and
made accessible at grade. The ADV will alternate dosed effluent to 5,280 square feet of soil treatment area between
five beds, each consisting of four rows of 22 Infiltrator Quick 4 Plus Standard chambers for a total of 440 Infiltrator
chambers. Maintain all elevations and setbacks, including encasement at waterline crossings, as shown in the
design drawing.
NOTE: The contractor must verify that all electrical components and inspections are covered under the electrical
permit associated with the Orenco Vericom control panel and pump connections. The alarm must be connected to a
separate circuit. Additional pump details are on the design drawing. Advantex systems must conform to the CDPHE
technology approval letter dated May 1, 2018.
Contact Eagle County Environmental Health and the design engineer well in advance of requesting inspections prior
to backfilling any component of the OWTS. The design engineer is responsible for conducting all inspections
necessary to certify the installation and assure functionality of the system. System certification, along with photos
and a record drawing is required to be submitted to, and approved by, Eagle County Environmental Health prior to
the use of the system or occupancy of the dwellings.

RE: Frost Creek - Onsite Wastewater Treatment System Design – Lots 102, 103, 104, Eagle
County, CO
Dear Claire:
JVA Inc. (JVA) has prepared a design of an onsite wastewater treatment system (OWTS) to
serve Lots 102, 103 and 104 within the Frost Creek PUD. JVA Inc. (JVA) is the designated
engineer to process all OWTS permit applications within Frost Creek. JVA has prepared the
OWTS design to be in general conformance with OWTS requirements of the PUD.
The 2019 annual Water Quality Monitoring Report prepared by Wright Water Engineers
documents exceedances of the 85th percentile background concentrations during sampling events
in 2019. The report states the following ‘The trends of water quality parameters seen throughout
the sampling of groundwater and surface water at the Frost Creek PUD have not reflected a
marked upward increase in concentrations of the sampled parameters. As more homes are
constructed on the Frost Creek PUD during 2020, the surface water and groundwater sampling
location will continue to be monitored’
Sincerely,
JVA, INCORPORATED

RE: Frost Creek, Hunter’s View Lots 102, 103 & 104 – Site and Soil Investigation Report for
an Onsite Wastewater Treatment System (OWTS)
JVA Job No. 1037.6e
Dear Claire:
Enclosed in this report are the results of the site and soil evaluation for proposed Hunter’s View
OWTS 2 serving lots 102, 103, & 104 located in Frost Creek, Colorado. This report provides
information needed to support the design of an OWTS including: results from the preliminary
investigation, the site visit, and the soil evaluation. Design calculations are included in the
drawing Permit Set attached.
PRELIMINARY INVESTIGATION
In preparation for a more efficient and informed site visit and soil evaluation, a preliminary
investigation was conducted the week of October 1st, 2019. Architectural site plans, aerial
imagery, and previous Geotechnical investigations were used for the preliminary investigation.
Geotechnical investigations were performed by HP Geotech in October 2002 across Frost Creek
for OWTS suitability; this geotechnical investigation has been submitted to Eagle County
previously. Results from the HP Geotech report showed that Test Hole A had a consistent silt
layer from grade to eight feet deep. Test Hole B had a silt layer from grade to six feet deep, and a
clay gravel layer from six to nine feet deep. No groundwater was encountered in either test holes.
SITE VISIT AND SOIL EVALUATION
A site visit and soil evaluation were conducted on October 9th, 2019 by James Cochran; James has
passed the Colorado Professionals in Onsite Wastewater (CPOW) Soils Evaluation Course. The
purpose of the site visit and soil evaluation was to confirm hypotheses from the preliminary
investigation, identify the topography, landscape position, vegetation, and site constraints for the
proposed OWTS, and to conduct a visual and tactile soil evaluation of the underlying soils where
the proposed soil treatment area (STA) is to be located for both suitability and sizing.
The topography of the site is on a ridge gently sloping from west to east. The dominant vegetation
at the proposed OWTS consists of native grasses. Site Constraints are shown in the Permit
Documents. For the visual and tactile soil evaluation, two soil profile holes were excavated using
a tracked excavator in the approximate locations identified in the Permit Documents. As seen in
Table 1 below, soil morphology for each soil profile hole from the surface up to seven foot deep
was consistent with a Soil Type 4, and from seven to eight feet deep with bedrock. Figures 1
through 4 below show the soil profile holes and corresponding morphology. No redoximorphic

features, indicating seasonally high groundwater, were observed in either profile hole. Therefore,
Soil Type 4 was identified as the soil type. The proposed STA will be five beds with the infiltrative
surface two feet below grade.

RE: Onsite Wastewater Treatment System Final Certification – 82, 86 & 90 Hunters View
Lane, Lots 102, 103, & 104
Dear Claire:
The Onsite Wastewater Treatment System (OWTS) covered under Eagle County Permit No.
OWTS-018538-2020 was installed by Beaumont Excavating for 82, 86, & 90 Hunters View
Lane. This letter certifies that the construction of the OWTS was completed as per the approved
design plan. The final record drawings from JVA, and construction photographs are provided as
attachments.
As part of the final approval process JVA observed that start-up was completed by the
manufacturer’s representative and completed a site visit to check all system components.
Although all unit processes function properly, the system cannot currently be remotely
monitored via Vericomm due to lack of internet infrastructure. CenturyLink is aware of the issue
and is upgrading the main panel in Eagle Spur. In the interim Frost Creek will have a more
concerted onsite effort by stopping biweekly to check the OWTS and respond to local visual and
audio alarms.
Sincerely,
JVA, INCORPORATED
