Re: Impact of Frost Creek PUD on water resources in Brush Creek Valley, upstream
from Town of Eagle, CO
Since 2003, Wright Water Engineers (WWE) has overseen the Water Quality Management Plan for
the Frost Creek PUD (previously known as Adam’s Rib Ranch). Our work has been conducted for
the owners of the PUD, working closely with the Eagle County Health Department. As part of this
effort, WWE has monitored the surface water in Frost Creek, Salt Creek, and Brush Creek as well as
the groundwater throughout the planned development. This had included water quality monitoring
during both construction and post-construction conditions, including biological monitoring every
three years. Limited wetland monitoring has also been conducted. We have been asked to provide
an overall finding regarding the impacts to date of the Frost Creek PUD on water resources in the
Brush Creek Valley. Based on all of the data that have been collected since 2003, and considering the
written agreement that was reached between the Eagle County Health Department and the previous
owner of Adam’s Rib Ranch regarding water quality monitoring and mitigation, there have not been
significant impacts (ie. impacts which exceeded the “trigger limits” established in the agreement) to
the surface waters that have been monitored.
Surface water trigger limits for the Frost Creek PUD were established in 2005 using historical water
quality data from the 1970s through the 1990s. Surface water trigger limits were established in April
2012 for the Salt Creek Equestrian Center Parcel using five years of background data. Surface water
trigger limits were established for Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Total
Phosphorus (TP), and nitrate/nitrite (NO3-/NO2-). The last four years of sample results are
summarized below to provide the basis for our finding that the Frost Creek PUD has not caused
significant adverse impacts to water resources.
During the 2012 sampling season there was one exceedance of TP in a surface water sample from
Salt Creek during the April sampling event. This exceedance was seen at the upstream (background)
sampling location and not at the location downstream of the PUD. Consequently, this exceedance
represented background water quality data. In both the August 2012 and September 2012 sampling
events, the Salt Creek locations exceeded trigger limits for TSS. These exceedances were attributed
to a newly constructed beaver dam upstream in Salt Creek and not attributed to impacts by the Salt
Creek Equestrian Center Parcel or the Frost Creek PUD.
November 3, 2015
Page 2
During the 2013 sampling season no trigger limits were exceeded.
During the 2014 sampling season there was one exceedance of TP in a surface water sample from
Frost Creek during the October sampling event. This exceedance was not consistent with a long term
trend of non-exceedance, one of the triggers in the original agreement.
The most recent 2015 sampling season results are summarized by excerpts from the June 2, 2015
letter to Ray Merry and Matt Shoulders from WWE.
“For both sampling locations of Brush Creek within the Salt Creek Equestrian Center Parcel
(SWBC-3 and SWBC-4), the trigger limits for TSS and TP were exceeded. These
exceedances of the trigger limits were likely caused by the rain event that occurred before and
during the sampling. This sampling event is not consistent with a long term trend but rather
shows a sudden increase in the TP and TSS concentrations found at SWBC-3 and SWBC-4.
These locations will be monitored closely in the future to determine if there is an increasing
trend.” [note: SWBC-3 is a background sampling point.]
“Based on the updated surface water trigger limits for the Salt Creek Equestrian Center Parcel,
the levels of TP at both SWSC-1 and SWSC-2 exceed the trigger limits shown in Table 4.
The TSS level at SWSC-1 exceeds the trigger limit shown in Table 4 as well. These
exceedances are not consistent with a long term trend but rather show a sudden increase in the
TP and TSS concentrations found at Salt Creek within the Salt Creek Equestrian Center
Parcel. These locations will be monitored closely in the future to determine if there is an
increasing trend.” [note: SWSC-1 is a background sampling point.]
There has been no exceedances of the trigger limits set for NO3-/NO2- in the past four sampling years.
On the basis of the data presented above from 2012 to 2015, the Frost Creek PUD has not significantly
adversely affected surface water quality.
Sincerely,
WRIGHT WATER ENGINEERS, INC.

RE: Frost Creek - Onsite Wastewater Treatment System Design – 967 Gray Rock Rd, Eagle
County, CO – Schmidt Residence
Dear Ray:
LKP Engineering Inc. has prepared a design of an onsite wastewater treatment system (OWTS)
to serve 967 Gray Rock Road located within the Frost Creek PUD. JVA Inc. (JVA) is the
designated engineer to process all OWTS permit applications within Frost Creek. JVA has
reviewed the OWTS design and has determined that it is in general conformance with OWTS
requirements of the PUD.
The most recently reported sampling results from the Water Quality Monitoring and Mitigation
Plan (dated July 13th, 2016) did not result in any exceedances of the water quality trigger limits.
Please proceed with the permit review of this OWTS design.
Sincerely,
JVA, INCORPORATED

RE: Soil and Site Evaluation
Lot 28, Frost Creek & Salt Creek PUD, Filing No. 1
0967 Gray Rock Drive
Eagle County, Colorado
Project NO. 15-3066
On October 7, 8, 12 and 13, and December 10, 2015, we visited the property on Lots 28,
Frost Creek & Salt Creek PUD, Filing No. 1, 0598 Frost Creek Road, Eagle County, Colorado.
The purpose of our site visits was to observe and test the site that meets the criteria of OWTS #43,
for a septic system for the proposed Schmidt Residence. Lot 28 is a 4.000 acre parcel of land at
0967 Gray Rock Drive, off of Frost Creek Drive, off of Brush Creek Road. Gray Rock Drive is a
loop road that has two access points on Frost Creek Road. Lot 28 is approximately 8.2 miles
south from Highway 6, along Sylvan Lake Road and Brush Creek Road, in Eagle, Eagle County,
Colorado. The septic system will have a secondary treatment in order to meet the Frost Creek
PUD regulations for nutrient removal.
!Preliminary Investigation
G Address:0967 Gray Rock Drive, south from the Town of Eagle, Eagle
County, Colorado
G Legal Description: Lots 28, Frost Creek & Salt Creek PUD, Filing No. 1,
Eagle County, Colorado
G Existing Structures: There were no buildings on the lot.
G Location of existing and proposed wells on property: Water is provided by
the Town of Eagle Water Department.
G ECEHD records: There are no existing septic systems on Lot 28.
G Topography: The topography of the property is rolling. Within the
proposed leachfield area the topography was moderate, sloping gently to
the east. The leachfield will be located on the lower, northeast portion of
the lot, in the back yard of the proposed residence.
G Soil Data: Two profile holes were excavated and observed. Profile hole
number one had about 5 feet of topsoil with roots and blocky clay, over one
foot of whitish-reddish, silty, sandy matrix with cobbles. The soil
encountered in the profile hole No. 2 consisted of about a foot of Topsoil
over 4 feet of reddish-brown, blocky clay over one foot of reddish-brown,
silty, gravelly sand. At 6 feet there were cobbles and boulders. There was
no ground water or bedrock observed in the profile holes at the time of the
excavation.

G Location of applicable setbacks in Table 7-1: The proposed septic tank is
about 20 feet away from the house, and at least 85 feet away from the
leachfield. The leachfield is at least 70 feet away from the house, and over
15 feet away from the closest property lines.
!Reconnaissance
G Landscape position: The proposed leachfield site will be located in the
back yard, on a convex slope, along the contours.
G Topography: The topography of the proposed leachfield site is moderate
(about 8 percent slope) and the trenches will run along the contours.
G Vegetation: The vegetation of the proposed leachfield site consisted of wild
grass and sage brush.
G Natural and cultural features: The natural topography of the site is
moderate with a gentle slope to the east. There is also a golf course
easement along the south two thirds of the east lot line.
G Current and historic land use: Based on the records available, the
property seems to have been used as a ranch by an early settler, W.E. Frost
from the early 1880's. From 1973 the land had been developed into the
residential subdivision Adam’s Rib Ranch with a golf course. Most
recently, in March of 2015 the property had been repurchased and
renamed to Frost Creek Ranch. The use remains as a residential
subdivision with a golf course.
