Colorado.
Dear Mr. Sills:
As requested, we have conducted a geotechnical study for the proposed development.
The property is suitable for ttre proposed development based on geologic and
geotechnicai conditions.
Subsurface conditions encountered in the exploratory pits excavated throughout the site
consist of up to about 1 foot of topsoil ovgrlying stratifid clayey to silry sand and sandy
silty clay, Grouudwater was encountered between 2r/z aad.7 feet in Pits 1 and 6-11.
Spread footings placed on the nahral subsoils and designed for qn allowable bearing
pressure of 800 psf to 1,500 psf appear suitable for building support. Excavations for
the building foundations should be kept relatively shallow to avoid soft wet soils with
dep&.
The report which follows describes orr exploration, zummarizes our findings, and
presents our recorlmeudations suitable for planning and preliminary desigu. It is
impo*ant that we provide cousultation during design, and field services durino
construction to review and mouitor the implementation of the geotechnical
recommendations
If you have any questions regarding this report, please contact us.

PIJRPOSE A}ID SCOPE OF STT]DY
This report presetrts the results of a preliminary geotecbnical shrdy for the
proposed Creek Side Estates Subdivision to be located on Colorado State Highvtay 325,
Garfieid County, Colorado. The project site is shown on Fig. 1. The puq)ose of the
study was to evaluate the geolo-eic and zubsurface conditions ald their potential impacts
on the project. The study was conducted in accordance with or:r agreemeot for
geotechnical engineering services to you, dated July 18, 20V2.
A field exploration pro$am consisting of a reconnaissaace and exploratory pits
was conducted to slrain inform.ation on the site and subsurface conditioas. $ernFles of
the zubsoils obtained during the field exploration were tested in the laboratory to
determine their classificatiotr, compressibility or swell and other engineering
characteristics. The results of the field exploration and laboratory testing were analyzed
to develop recommendations for project planning and preliminary desiga. This report
summarizes &e data obtained during this study and presents our conclusions and
recommendations based on the proposed development and subsurface conditions
eucountered.
PROPOSED DE\MLOPMEI\TT
The proposed development consists of 6 lou as shown on Fig. 1. A single
family residence is proposed at each lot except for Lot 4 which is already occupied by a
residence. We assume construction on the rernaining 5 lots will be typical of the area
and consist of one or two story wood frame residences. Ground floors could be slab-
on-grade or structural over a crawlspace. Access to Lots 1-5 will be from a cenEal
drive which will enter the development at the southwest corner of the property. Lot 6
will have a driveway off of State Highway 325 at the northwest corner of the lot. The
development will be serviced with individual water wells and septic diqposal systems.
The feasability of infiltration septic systeu$ is being evaluated by Boundaries
Unlinited.o
H-P GEoTECH

-') -
If development plals change siguificantly from those described aboye, we should
be aotified to re-evaluate the recommendations presefted in this report.
SME CONDITIONS
The site is mostly fallow irrigated pastures. State Highway 325 borders the
property to the west and Rifle Creek generally follows the eastern side of the property
with a small tributary joining the main channel in the south. Lot 4 is currenfly
developed with a relatively new residence. A few abaudoned irrigation ditches cross
the site. Freliminary site grading was underway at the time of our field exploration.
Access has been rough graded into the site including fiils up to about 3 feet deep along
the proposed road alignment. The ground surface throughout the site is relatively flat
aud slopes down to the southeast at grades between about 2 arrd 5 percent. Steeper
slopes are located aloug Rifle Creek and its tributary. Vegetation coi.sists mosfly of
native gmsses with mature trees and brush along State Highway 325 and Rifle Creek.
GEOLOGIC SETTING
The Creek Side Estates Subdivision is located on the valley floor of Rifle Creek
about one mile south of where Rifle Gap cuts through the Grand Hogback. The Grand
Hogback is a major regional monocline along the treqsitiotr betweeo the White River
uplift and the Piceance basin. These regional struchres were formed druing the
Laramide Orogeny about 40 to70 miltiea years ago. Regional geologic mapping shows
the Shire member of the Eoceue aud Paleocene-age Wasatch Formation is present in the
project area (Schroba and Scott, L9E7). Outcrops to the west of the project site
indicates that the beddiug in the Shire member strikes to the aorthwest and dips about
26" to the southwest, see Fig. 1. This is consistent with the regional structure. Major
faults are not kuown to be present iu the project vicinity (Schroba and Scott, L997).
The closest fault zotres to the project site with kuowu or suspeited Holocene movement
(movement within about the past 10,000 years) are the Roubideau Creek fault zoneo
H-P Georrcrr
-3-
o located about 79 miles to the southwest and the Vlilliams Fork Mountain fault zone
located about 83 miles to the northeast (Widmann and Others, 1998). Late Pleistoc€ne
aud Holocene-age creek terrace alluvftrm, ailuvial fans and colluvigm cover the Shire
member at the project site.
SITE GEOLOGY
The majel geologic features at the project site are shown on Fig. 1. Resistant
sandstone beds in the Shire member of the Wasatch Formation (Tws) crops out locally
on the valley side to the west of the project site. The Shire member is made up of
varied colored claystone, mudstone aud siltstone interbedded with less abundant,
coarse-grained sandstone (Schroba and Scott, 1997). Formation rock was aot
encountered in our exploratory pits and it is expected to be present well below tlpicai
residential foundation depths at the project site.
Shallow colluvium (Qc) usuaily covers the formation rock on tle steeper valley
sides to the west and thin colluvium is also present along the creek foenks of Rifle Creek
and its tributary in the southern part of the project site. Surficial soil deposits elsewhere
are alluvial fans (Qafl that have developed at the mouths of tributary drainages along
the western valley side and Rifle Creek terrace alluvium (Qtl). The modern charnel of
Rifle Creek lies about 10 feet below the adjaceat terrace surface. The creek channel
banks are very steep, subject to r:ndercutting and erosion duriug flood flows aad are
poteutially unstable. Observations and samples from our exploratory pits ind^icate that
the creek terrace alluvium (Qtl) and alluvial fan deposits (Qaf) consist of interstratified
low plasticity sandy clay and silty to clayey saud. SamFles tested indicate a minor
expansisa potential and moderate compressibility after wetting under typical residential
foundation loads.
' Relatively shallow groundwater was etrcoutrtered in most of the exploratory pits
and vegetation indicative of poorly drained conditions is present over mubh of the
westertr and northwestertr part of the property. The shallow groundwater appears to be
a perched condition associated mostly with irrigation ditch transmission losses.

The field exploration for the project was conducted oo August L6,2W2. Eieven
exploratory pits were excavated at the locations shown on Fig. 1 to evaluate the
subsurface conditions. Pits 2, 4,6 and 10 were excavated for percolation testing by
others prior to our arrival to the site. The remaining pits were dug with a Ford 555A
rubber-tfued bactfioe. Locations of the pits were directed in the field by Mark Sills
based upor approximate proposed. buildiug iocations. The pits were logged by a
represeatative of Hepworth-Pawlak Geotechnical, Inc.
Samples of the subsoils were taken with relatively uadisturbed and disturbed
sampling methods. Depths at which 1trs semFles were taken are showu on the Logs of
Eryloratory Pits, Fig. 2. Thesamples were returned to our laboratory for review by
the project eugineer and testi:rg.
SUBSTIRFACE CONDITIONS
Graphic logs of the subsurface conditions eocountered at the site are shown on
Fig.2. The subsoils consist of up to about 1 foot of topsoil overlying stratjfied clayey
to silty sand and sandy silty clay.
Laboratory fssring performed on samples obtained from the pits included naftral
moisture conteat and density, percent finer than sand size gradation analysis and
uuconfined compressive strength. Rezults of swell-consolidation testing performed on
relatively undisturbed drive samples, preseuted on Fig. 4, indicate iow compressibility
under existing moisture conditions and light loading and a minor expansion potential
when wetted. The samples showed moderate compressibility with increased loading
after weuing. The laboratory testing is summarized in Table I.
Free water was eocoutrtered in Pits l, 6,7,8, 9, 10 and 11 at depths betweeu
2r/z andT feetbelow the ground surface. The subsoils above the water level were
slightly moist to very moist.

o GEOLOGIC A,SSESSMENT
Building oD the lsmaining five proposed lots should be feasible based, on
geologic conditions. Several conditions of a geologic nature that could present
constraints to buiiding on the lots and should be considered during project planning and
design ars discussed below.
FLOODING AND STORM WAIER MANAGEMENT
A hydrologic study should be conducted to assess the flood potertiat at the
proposed buildiug sites. There is a potential for flooding along Rifle Creek aud
flooding should also be considered along the tributary drainage that enters the project
area from the west. Floods associated with intense thunderstorns will likely foays high
sediment coaceutrations and may also have considerable debris. This should be
considered in the flood poteutial assessments.
CREEK BANK EROSION
The steep creek banks along Rifle Creek are potentially uustable and zubject to
undercutting and erosiou during flood flows. Because of this, it is recommended that
building sites not be located within 50 feet of the top of the creek bank escarpmetrts
shown on Fig. I unless channel stabilizations is considered.
EARTHQUAKE CONSIDERATIONS
The project area could experience earthquake related grouud shaking. Modified
Mercalli Intensity YI grouud shaking should be expected during a reasonable seryice
life for the developmetrt, but the probability for strouger ground shaking is low.
Intensity YI ground shaking is felt by most people and causes geueral alarm, but results
in negligible damage to structues of good desigu and constnrctiou. Occupied stnrctures
should be designed to withstand moderately strong ground shaking with little or tro
damage and not to collapse under stronger gronud shaking. The project is in the
H-P GEoIECH
o

Uniform Building Code, Seismic Risk Zone 1. Based oa our current understanding of
the earthquakehazwd iu this part of Colorado, we see tro reason to increase the
commonly accepted seismic risk zone for the area.
PRELIMtr\ARY DESIGN RECOMMEFIDATIONS
The conclusions and recommendations presented below are based on the
proposed development, zubsurface conditions etrcountered in the exploratory pits, md
our experience in the area. The recommendations below are zuitable for planning and
prelirninary desrgn. Site specific studies should be conducted ouce building footprints
and proposed constnrction have been determined.
FOUNDATIONS
Bearing conditions will vary dependiug on the specific location of the buildings
on the property. Based on the trature of &e proposed construction, spread footings
placed on the upper natural soils should be suitable for buildiug support. We expect the
footings can be sized for an allowable bearing pressure in the raage of 800 psf to 1,500
psf. Excavations for the building foundation should be kept relatively shallow to avoid
soft wet soils with depth. Trench drains to intercept and lower the groundwater level
on Lots 1, 5 aad 6 prior to construction could be needed. Expansive clays encountered
on Lots 2 artdS may need to be removed or the feetings designed to impose a minimurn
dead ioad pressure to limit potetrtial heave. Foundation walls should be designed to
span local anomalies and to resist lateral earth loadings wheu acting s5 istaining
structures. Below gade areas and retaining walls should be protected ftom wetting and
hydrosutic loading by use of an uaderdrain system. The footings should have a
midmum depth of 36 inches for frost protection.
ELOOR SLABS
Slabon-grade constnrction should be feasible for bearing ou the natural soils.
The clay coils on Lots 2 and 3 were found to have a minor expansiea potential when
H-P G.eorecn
o

wetted under light loading. To reduce the effects of some differential movemetrt, floor
slabs shouid be separated from ail bearing walls and columns with expansion joints.
Floor slab control joints should be used to reduce damage due to shrinkage cracking. A
minimtrm 4-inch thick layer of freedraining gravel should underlie interior floor slabs
to facilitate drainage.
UNDERDRAIN SYSTEM
Free water was ercountered in some of the exploratory pits and it has been our
experience in the area that local perched groundwater can develop during times of heavy
precipitation or seasonal nruoff. An underdrain system should be provided to protect
below-grade construction, such ss lstaining walls, crawlspace and basement areas from
wetting and hydrostatic pressure buildup. The drains should consist of drainpipe
surrounded above t}e invert level with freedraining granular material. The drain
should be placed at each level ofexcavation and at least 1 foot below lowest adjacent
finish grade and sloped at a minimum 7% to a suitable gavlty outlet.
SURFACE DRAINAGE
The grading plan for the subdivision should consider runoff from uphill slopes
through the project and at individual sites. Water should not be allowed to pond which
could impact slope stability and foundations. To limit infiItration iuto the bearing soils
next to buildings, exterior backfill shouid be well compacted and have a positive slope
away ftom the building for a distauce of 10 feet. Roof downspouts and drains should
discharge well beyond the limits of all backfill and landscape irrigation should be
restricted.
LINIITATIONS
This study has been condueted according to generally accepted geotecbnical
engineenng principles and practicgs in rhis area at this time. We make no warranty
either expressed or implied. The conclusions and recommendations submitted in thisT

Subject:Gaurma Radiation Survey, Proposed Creek Side Estates Subdivision,
Colorado State Highway 325, Garfield County, Colorado
Dear Mr. Sills
As requested by Bruce Lewis, we performed a gamma radiation survey at the subject
site. The findings and conclusions are preseiled in this report. The survey was
performed as a supplement to our previous services agreement with you dated luly 18,
ZOO2. We previously conducted a preliminary geotechnical study for the project atrd
presented our findings in a report dated September 30,20V2, Job No, 102 497.
Proposed Development: The development will consist of 6 lots for single family
residences. Access will be'off of State Highway 325 with a culde-sac street. The
property qurently consists of mostly irrigated pa.stures with an existing resideD,ce
located on Lot 4.
Radiation Survey: A gamma radiation survey was conducted in the development area
on March 3,2003 by a represetrtative of Hepworth-Pawlak Geotechnical, lnc. Gamma
radiation measurements were taken on about 100 foot spacings as shown on Figure 1
using a Ludlum Model 3 survey meter and Ludlum Model44-9 detector. The readings
were taken about ZYz feet above the ground surface. A total of 86 survey points were
taken and the readings ranged from 0.02 to 0.03 millirems per hour. Background
readings aken approximately Vz mile north of the property were 0.025 millirems per
hour.
Conclusions: The gamma radiation readings taken at the subject site appear to be
rypical of natural background levels iu the area. No mitigation of the radiatiou should
be required.a

atfect timber harvest, and special care is needed to
prevent erosion.
Elk, deer, black bear, and grouse lind habitat on this
soil.
Slope and large stones limit community development.
Special design overcomes these limitations.
This soil is in capability subclass Vlle, nonirrigated.
26-Farlow-Rock outcrop association, steep. This
broadly delined map unit consists ol moderately steep to
steep Farlow soils and Rock outcrop on mountainsides.
Elevation ranges frorn 8,000 to 10,500 feet. The Farlow
soil lormed in residuum lrom limestone. The average
annual precipitation is about 19 inches, the average
annual air temperature is about 38 degrees F, and the
trost-free period is less than 75 days.
The Farlow soil makes up about 65 percent ol the
association, and Bock outcrop makes up about 25 per-
cent.
The Farlow soil is deep and well drained. Typically, the
surface layer is dark grayish brown channery loam about
10 inches thick. The substratum is light gray and pale
brown very channery loam and extremely flaggy loam
about 32 inches thick. Weathered limestone is at a depth
of 42 inches.
Permeability of the Farlow soil is moderate, and availa-
ble water capacity is low. Eftective rooting depth is about
40 to 60 inches. Surface runoff is rapid, and the erosion
hazard is moderate
The Flock outcroP is limestone.
lncluded in mapping are small areas of Dateman soils,
generally in depressions. These areas make up 5 to 15
percent of the maP unit.
This association is used mainiy ior limited grazing and
wildlile habitat.
The native vegetation is mainly needlegrasses, wheat'
grasses, and serviceberry.
When range condition deteriorates, forbs and shrubs
increase. When the range is in poor condition, undesira'
ble weeds and annual plants are numerous. Properly
managing grazing maintains and improves range condi'
tion.
Elk, deer, black bear, and grouse find habitat on this
soil.
Community development and sanitary facilities are lim-

27-Halaquepts, nearly level. This broadly defined
unit consists of deep, somewhat poorly drained to poorly
drained, nearly level and gently sloping, salt-atfected
SOIL SI.IFVEY
soils in narrow foothill valleys, on fans, and on low ter-
races. Slopes e,re 0 to 6 percent. These soils formed in
alluvium.
The soils are extremely variable. The upper 24 inches
ranges from loitm to clay, and the underlying layers are
generally gravelly. The soils are commonly gleyed lrom
the surlace down. Stratified sand, gravel, and cobbles
are at a depth of 24 lo 40 inches. ln some areas, gravel
and cobbles arr> at or near the surface.
lncluded witlr these soils in mapping are small, isolat-
ed areas ol Arvada, Limon, and Heldt soils that have
slopes of 1 to 6 percent. Small areas of severely alkali-
aflected soils are identilied by an alkali spot symbol.
These areas nrake up 10 to 15 percent of the map unit.
The water table is at or near the surface at tirnes,
mainly during s;pring and summer. The level of the water
table is strongly influenced by the seasonal water level in
nearby streanrs and rivers and higher lying irrigation
ditches. Water seeps lrom the ditches into these soils.
These soils are subiect to rare or occasional flooding.
This unit is used mainly lor grazing.
Some hay isi grown in areas drained by ditches. Yields
are low because ol saline condition. Alkali-tolerant
grasses and k:gumes must be grown for productive hay
and pasture.
The native vegetation consis{s of willows, tamarisk,
cottonwoods, and alkali- and water-tolerant grasses.
Game birds, rabbits, deer, and other wildlile find habi'
tat on these soils. Ducks and geese neSt in the more
swampy areasi. Mourning doves nest in the cottonwoods
and tamarisk. Babbits and deer lind adequate food and
cover on ther;e soils. Where the soil has been drained
and is suitable for hay and pasture, planting food plots,
trees and shrrrbs, and nesting cover enhances habitat for
upland wildlife. Where the water table is high, open
water lor waterfowl can be developed by blasting or
excavating.
Community development is limited by flooding and
depth to waler table. Onsite investigation is necessary
for appropriate design and construction to overcome
these limitations.
These soikr are in capability subclass Vlw, nonirrigat-
ed.
28-Heldt clay loam, 1 to 3 percent slopes. This
deep, well drained, nearly level soil is on alluvial lans
and sides ol valleys. Elevation ranges from 5,000 to
6,000 feet. This soil lormed in line textured allwium
derived from shale and sandstone. The average annual
precipitation is about 14 inches, the average annual air
temperature is about 48 degrees F, and the average
trost-free period is about 120 days.
Typically, 'the surface layer is grayish brown clay loam
about 8 inctps thick. The subsoil is light brownish gray
clay loam atrcut 13 inches thick. The substratum is light
gray clay to a depth of 60 iriches.

Re: Weed Inventory Creek Side Estates
Dear Phil:
At your request, I have completed a noxious weed inventory of the proposed Creek
Side Estates Subdivision north of Rifle, Colorado. The entire property was evaluated
and only a small amount of noxious weeds were found to exist. These included
limited numbers of Canada thistle, plumeless thistle, field bindweed, tamarisk, hoary
cress and volunteer rye.
The attached report includes a drawing showing the location of these weeds, which
can be used to control the spread of these weeds to other areas of the property and
adjacent properties.
If you have any questions, please give me a call.
Sincerely

o NOXIOUS WEED INVENTORY
AND MANAGEMENT PLAN
FOR
SILLS CREEKSIDE
This noxious weed survey and management plan is for the 14.5 acre portion of the Sills
Creekside property and is designed to maintain and/or establish a desirable native plant
community while controlling noxious weeds. This management plan is designated for all
common areas including roadsides, open space, ditch, and utility easements.
Recommended control measures for weedy species will include cultural, mechanical,
chernical, and biological techniques. It is our recommendation that chemical control be
limited to the ma:rimum extent possible and only reserved for large outbreaks of noxious
weeds.
Site Vegetation Characterization
The Bair Chase property is located just northof Rifle, Colorado along State Highway 325
and falls within the Rocky Mountain Region of Colorado. The land evaluated as a part of
this study includes historically irrigated pastures, an existing gravel roadway, areas where
vegetation has been disturbed and improved residential land, all shown in photographs
and mapping contained within appendices to this report. The site can be characteriied as
a montane life zone comprised of grasslands, sagebrush, rabbitbrush and wetland
communities. Dominant vegetative species of the area evaluated includes wheatgrasses,
fescues, timothy, sweet clover and various peppergrasses and mustards in the herbaceous
strata, sedges and rushes in the wetland community and cottonwood and willow as the
dominant tree species. Other grasses and grass-like plants noted during the site
inspection included crested wheatgrass, bluegrass, orchard grass, brome and juncus.

o Soil Characterization
Information about soils is provided by soil surveys from the United States Departrnent of
Agriculture Soil Consenration Service. The primary soil type on the Sills Creekside
property is Halaquepts, a broadly defined unit of deep, somewhat poorly drained soils
lying on nearly level to gently sloping land. This soil unit includes Arvada, Limon and
Heldt soils and the top 24 inches are typically loams to clay with gleyed soils from the
surface. The existence of these soils was confirmed during the site visit to the property.
There is approximately 10 acres of previously irrigated pasture that has been proposed for
additional development. Permeability of the soils is moderate; available water capacity is
moderate and erosion potential is also considered moderate. This soil is typicallyused
for irrigated hay and for dry land farming. The native vegetation includes western
wheatgrass, needlegrass, mountain muhly, peppergrass, mustard, tall sage, rabbitbrush,
narowleaf cottonwood and Bebb willow. These plant species were all noted during the
site visit.
Noxious Weed Characterization
During the noxious weed survey, Beach Environmental,LLC,noted outbreaks of weeds
were primarily confined to recently disturbed areas. Communities or individual plants of
Canada thistle, Plumeless thistle, field bindweed, hoary cress, volunteer rye and tamarisk
were noted primarily along the driveway or in fields where land disturbance has occurred
and in the case of the tamarisk, along Rifle Creek and a small drainage way on I-ot 2 . In
most cases the areas affected were small and control should be'relatively easy. Canada
thistle was found most often but was limited to recently disttrbed sites.
Due to the aggressive nature of these weeds, the vegetation management plan has
established guidelines to help conhol the spread of these species. These guidelines are
reproduced from recommendations provided by the Native Plant Revegetation Guidefor
Colorado, a guide published by Colorado Natural Areas Program, Colorado State pari(s,
and Colorado Department of Natural Resources and recommended by Garfield County
for planning putposes. Other resources such as the Pitkin County Weed Management
Plan and the Colorado Weed Management Association were used for supplemental
information. A description of our findings and recommendations is included in the
following sections of this plan.

Canada Thistle (Cirsium arvense)
Description: This aggressive weed forms large dense patches of
prickly plants along the bottoms of intermittent drainages and
other areas with moist soil. This thistle, however, does not do as
well in continually saturated or inundated soils (although, it does
grow in seasonally saturated or inundated sites). It is extremely
difficult to eradicate because it has an extensive root system and
new plants can grow from even a small piece of root. One plant
can colonize an area up to six feet (1.8 meters) in diameter in ort
or two years. Canada thistle grows to three to five feet (l-1.5
meters) tall, has spine-tipped leaves, smooth stems, and small
lavender flowering heads.
canada thistle is the dominant noxious weed on Sills creekside
property and individual plants number close to one hundred.
Canada thistle was identified in small numbers in disturbed areas upon Lot 1,2,3,5 and
6. The highest concenhation of thistle occurs on lots 1 and 6 along the excavated
drainage ditches and spoil piles adjacent to them.
Management Measures: In addition to prevention, the critical management measure is
to stress the plant by forcing it to use stored root nutrients. The most effective way to
prevent this species is to revegetate moist, bare soil.
Cultural Control: After establishment, competition with other plants is helpful, but not
completely effective in controlling this weed. Reseeding is often necessary after the
thistle has been removed from an area. Keeping the area at optimal fertility and moisture
levels to encourage gftrss growth is beneficial.
Mechanical Control: Mowing can be effective when combined with herbicide
treatments, especially in areas with competition with established grasses. Mow
throughout the growing season and then treat with herbicides in the fall. Mowing alone,
without herbicides, can be effective if done at one-month intervals over several years.
Late spring burning will also stress the plant if sufficient dead plant material is available
to carry a fire hot enough to kill spring rosettes. Burning will have to be repeated
annually for several years or at three-year interuals. Pulling and digging the plant is
typically ineffective due to its extensive root structure.
Chemical Control: Herbicides can be effective, especially when combined with
mowing, tilling, and competition with other plants. The larva of the weevil Ceutorhyncus
Ittura bores into Canada thistle and weakens the plant. This weevil will not control
Canada thistle alone, but can be combined with other methods. (lrophora cardui,
Cassidia rubiginosa, and the painted lady butterfly are other biological control options
for this weed. Releasing a combination of these insects is recommended, so everypart of
the weed is attacked. Where chemicals cannot be used (water ways and riparian areas),
grazingcan be employed in the spring and early sunmer to help control thistle migration.
Sills Creekside property Weed and Vegetation Management plan
Beach Environmental, LLC Page 3
Biologic Control: Grazing goats have been found to be an effective way of reducing
thistle populations since the seed is digested as a general rule. Grazing goats must be
returned to the site until the seed bank has been depleted.
Plu meless Thistle (Carduus acanthoides L.)
Description: Plumeless thistle is a member of the Aster
Family, Thistle tribe. It is an inhoduced winter annual or
biennial. This plant can be distinguished from musk
thistle by its smaller flowers - ll2to I inch in diameter. The
leaves of plumeless thistle lack the prominent white margin
present on musk thistle leaves. The plant may
grow to a height of 5 feet or more. Flowers are reddish-purple
and are either solitary or clustered. Taproots are large and
fleshy.
Plumeless thistle is an exffemely prolific seed producer. It is
found in pasfures, river valleys, and along roadsides. It is
rapidly increasing in this state, particularly in Colorado's Garfield, Garfield, and Eagle
Counties.
Individual plants were noted along the disturbed edges of driveway and individual plants
were found in disturbed areas of lots 1,2 arrd 6. The numbers of Plumeless thistle found
during the survey were considered minimal and appeared to total less than 20 plants. A
few more individual plants were located on the property and appear to have been spread
by flood irrigation.
Management Methods: kr addition to prevention, the critical management measure is to
stress the plant by forcing it to use stored root nutrients. The most effective way to
prevent this species is to revegetate moist bare soil.
Cultural Control: After establishment, competition with other plants is helpful, but not
completely effective in controlling this weed. Reseeding is often necessary after the
thistle has been removed from an area.
Mechanical Control: Mowing can be effective when combined with herbicide
treatments, especially in areas of competition with established grasses. Mow throughout
the growing seiron and then treat with herbicides in the fall. Mowing alone, without
herbicides, can be effective if done at one-month intervals over several years Late spring
burning will also stress the plant if sufficient dead plant material is available to carry a
fire hot enough to kill spring rosettes. Burning will have to be repeated annually
-for
several years or at three-year intervals.

Chemical Control: Herbicides can be effective, especially when combined with
mowing, tilling, and competition with other plants. Mow two or three times in the
sunmer at monthly intervals (beginning at bolt to early bud-growing stage) and follow
with a fall application.
Biological Control: Grazing by goats has shown to be an effective way to control this
weed. Grazing must occur over a period of several years in order to effectively eliminate
the seed bank.
Volunteer Rye (Secale cerale L.)
Description: Volunteer rye, also called common or annual
rye, is mostly an annual that is believed to be derived from
S. Montanun a perennial native in the mountains of
southwestern Asia. The first blade is tall, narrow, and
vertical. Blades are covered with short hair and have
prominent veins above and a midrib below. Sheaths are
covered with short hairs. The spikes are 4 to 6 inches long,
slender and long-bearded.
wheat fields of Colorado and
Volunteer rya, zmember of the Grass family, can be found
throughout Colorado in wheat fields, roadsides, ditches,
and waste places. It has become a major problem in the
diminishes crop yield by 8 to 10 bushels per acre.
Volunteer rye was found along the single driveway from highway 325. Volunteer rye
was also located
quantities.
just to the south of the driveway on Lots 2 and,3 but in very small
Management Methods: The key to controlling this weed is to prevent seed production
and dissemination.
Cultural Control: The most effective way to prevent invasion ofthis noxious weed is to
revegetate disturbed areas as soon as possible with native grass seed.
Mechanical Control: Removal of plant and root system. Revegetate as soon as possible
with native grasses.
Chemical: Various chemicals - herbicides have worked with dicamb4 picloram and
gllphosate providing good effective control results. 2-4-D has positive control results.
Biological Control: None. Grazinghas not shown to be an effective method of control
and volunteer rye is an irritant to grazinganimals due to the length of the awns.

o f ield Bindweed (Convolvulus arvensis)
Description: Field Bindweed is a member of the morning
glory family. This creeping perennial was introduced from
Europe. It reproduces by seeds and horizontal roots. The
stems are smooth, slender, slightly angled, I to 4 feet long, and
spreads thickly over the ground or winds around erect plants or
other objects.
The leaves are alternate, I to 2 inches long, with great
variation in shape, they are somewhat arow-shaped with
spreading, pointed, or blunt lobes at the base. The flowers are
bell or trumpet-shaped, white or pink and about 3/4 to I inch
broad. Only white flowered bindweed was found on Sills
Creekside property along the upper part of driveway and in the
area of the leachfield between lots 4 and 5.
The seeds are very resistant to damage and remain viable through the digestive tracts of
birds that commonly eat and disperse them. Seed also moves with feed and seed supplies
or clings to the mud on farm vehicles. The seed can move extensively by water, andieed
buried in the soil may be viable for up to 40 years. Spread also occurs by the perennial
rootstocks of the plant, which produce root and shoot buds. A 2-3 year food supply is
stored in the root system thus making it difficult to control. The roots can be very deep
and extensive, and produce many new plants.
Field bindweed was noted along ditch alignments and both pink and white flowered
bindweed was noted. The bindweed is not significant and should be easy to control.
Management Methods: In addition to prevention, a critical management method is to
stess the plant by forcing it to use stored root nutrients. The most effective way to
prevent this species is to re-vegetate moist, bare soil.
Cultural Control: Field Bindweed normally grows low to the ground, which gives it a
disadvantage in competing effectively for sunlight in established crops. Constant tillage
will deprive the plant of underground food reserues, gradually decreasing the root quality,
and eventually controlling the weed effectively. The best control can be achieved by
combining rotation of competitive crops, cultivation, and herbicides.
Mechanical Control: Continuous moving triggers plant re-growth, which uses up
available food supplies, leaving it susceptible to control by pesticides or grasses. Tillage
is an ineffective tool for bindweed control because the tilling action does not cut the root
into small enough pieces to prevent re-growth. Root pieces as small as a quarter of an
inch can sprout new plants.
Chemical Control: Fall is the best time to heat Field Bindweed to achieve good control.
Systernic herbicides that are trans-located from the foliar vegetation to the roots are

s,a*-
o required for good long-term field bindweed control. Recommended herbicides ue2,4-D,
Banvel, gllphosate, or dicamba. Chemical treatrnents tlpically take about three years to
be successful.
Biological Control: Aceria malherbae. a gall forming mite, and Tyta luctosa are two
insects that can help control Field Bindweed.
Hoary Cress (Cardaria draba)
Description: Hoary cress is a member of the
Mustard family and is commonly referred to as
whitetop. It is a cree'ping perennial that
reproduces by root segments and seeds. The root
system extends both horizontdly and vertically.
Hoary cress can grow lGl8 inches high. Flowers
are produced in late April and May. The leaves
are commonly covered with white hair, and the
flowers are gray-white in color. Leaves are Yz-2
inches long and are oblong, with toothed margins. Hoary cress was found in several
locations on Sills Creekside property but in very small quantities. Control should be
relatively simple.
Cultural Control: If perennial native grasses are seeded in weedy areas, this will help to
establish competition, thereby weakening the weed.
Mechanical Control: Removal of the top growth has been shown to be somewhat
effective. This treatment must be repeated at least twice a year to reduce seed production
and spread.
Chemical Control: Roundup (gllphosate) applied as aT%o solution at the flower stage
has resulted in fairly good control. 2,4-D applied at 3 qts/acre 2 to 3 times per year for 3
years has also been somewhat effective. The best time to apply herbicides on
Whitetop is in May or early June before flowering.
Biological Control: None currently available.

Weed Surveys
When controlling weeds, the weed manager shall be on the lookout for outbreaks of other
weedy species including but not limited to:
Planting and Weed Control Schedule
The proposed schedule for weed control upon the Sills Creekside property property is
mechanical removal of weeds monthly during the summer months of June, July, and
August, followed by a chemical application during the month of September. Due to early
flowering in April and May, weed control should be started as soon as possible.
Mechanical or chemical control can be applied to weeds to begin control. Weed
inspection and control should continue throughout the summer months of June, July, and
August.
This schedule is geared towards the removal of the most common weeds on-site (thistle).
Weedy species such as volunteer rye require similar schedules and techniques for control
and elimination. It is important that the weed confrol schedules remain flexible and
accommodate a variety of weeds. The weed manager is responsible for identiffing
outbreaks and, if necessary, redesigning the schedule to control that particular weed.
Once weeds are removed, it is important to reintroduce site appropriate native vegetation.
This will help prevent the return of weeds to that area. Revegetation with native seed
materials should occur annually during planting season until control is achieved. Seeds
should be planted within two weeks of shipment. The revegetation site must be prepared
and wetted prior to planting. Additionally, supplemental watering shall occur after
planting to ensure a high survival rate of native seeds. This can be accomplished through
on-site irrigation.

a CREEK SIDE ESTATES
WILD FIRE MITIGATION PLAN
The ground surface of the property slopes uniformly downward to the southeast,
beginning with an 8 to l0 foot embankment at State Highway 325 and gradually
flattening out as the ground approaches the banks of Rifle Creek. There is a drainage
swale running approximately down the center of the property, and a drainage channel
running approximately parallel with the southern property line. The property has little
vegetation other than field grasses and riparian vegetation, along with a cottonwood hee
stand near the embankment of State Highway 325 andthe existing access road.
Wildfire fuel sources are classified as light, moderate and heavy. Grasses are rated as
light fuels, shrubbery & sage are rated as moderate fuels, and trees are rated as heavy
fuels based on the intensity of the fires they produce. Ladder fuels are vegetative
materials that provide vertical continuity from the ground surface up into the branches of
trees. The continuity of the fuel source is the measure of the fuel hazard that includes
horizontal and vertical continuity. Ground slopes increase the continuity of the fuel
hazard. Cunently, the proposed building sites can be classified as light fuel hazard due to
the field grasses located on site.
A 30,000-gallon pond will be installed with a dry hydrant located at Creek Side Drive to
utilize for fire protection.
Additional mitigation measures for the site shall include landscape design criteria and
maintenance practices with the intent to limit horizontal & vertical continuity. The
following design standards shall be implemented:
Individual propane tanks are to be placed in a location where they are not
subject to damage, and combustible materials are to be kept a minimum of 10
feet away from tanks.
Trees greater than 15 feet in height at maturity shall have a minimum spacing
of 10 feet between the edges of the crown. Dead trees shall be cleared and
removed.
Spacing between clumps of brush and/or shrubs shall be 2.5 times the height
of the vegetation.
The maximum diameter of the brush and/or shrub clumps should be two times
the height of the vegetation measured at the crown of the vegetation.
All ladder fuels should be removed from under brush, shrubs and tree
canopies.
Non combustible ground cover (gravel) should be placed under trees, brush &
shrubs to the edges of the crown, or the vegetation should be pruned to a
height of l0-feet above the ground or Yzthe height of the plant, whichever is
least.
Lawns should be kept to a morimum height of 4 inches.O
Brush should be removed around the perimeter of all residential stnrctures for
a distance of 2.0 times the height of the brush or completely removed within
l0-feet of any residence and frimmed down to a height less than 5-feet within
2O-feet of any residence.
To aid in the location of structures by fire persorurel, addresses should be posted where
the driveway intersects with Creek Side Drive. Letters should be a minimum of 4 inches
in height, ll2 inchin width and be in contrast with background colors.

of the following components:
A.Prevention and Control. The quick revegetation of disturbed areas
with weed free grass seed and the maintenance of native or
introduced vegetation in the healthy, vigorous condition producing
optimum vegetative densities will leave noxious seed little
opportunity to establish. The use of hay that is certified if also
recommended.
Inventory. Each Lot should be inspected to identify any
infestations of noxious weeds. An accurate record should be kept
of the application and success of weed eradication efforts.

C. Eradication. Elimination of noxious weeds can be achieved
through:
(i) Mechanical controls which physically remove the entire
weed plant or eliminate the plant's ability to produce seed.
(ii) Biological controls which rely on organisms (insect
plant pathogens) to interfere with weed growth.
(iii) chemical controls which use herbicides to eliminate
water
D In the event the Owner fails to effectively control noxious weeds
on his or her own Lot, the Association shall have the right to enter
upon any Lot and conduct a weed control program within the area
of such Lot at the cost of the Owner.
E. An effective weed management program may involve all three
methods of eradication set forth in section c. above, as well as
long term commitment to prevention and control. Assistance in
the development and implementation of a week management
program is available through the Colorado State University
cooperate Extension Service and from the Garfield county office
of Vegetation Management.

Box 1300 Rifle; and Ann catherine Robinson, 425 county Road 25r, Rifle.
The property consists of historically irrigated pastures, which gently slope east towardRifle creek' The aforernentioned impacts to the wetlands occurred only on lots I and 6.The grading, dredging and filling ""tiritir. i-p".t"a noo-ti"r wetlands on the property.
Lot I lies immediately north of the entrance drive to the sills property and includesapproximately 2'14 acres of open meadow. of this amount an estimated 1.2 acres hasbeen graded and drainage a ditch has been constructed on the North end ofthe lot. As
o shown in Photo I the areas of disturbances corrmence at the approximate harf way pointofthe lot and extends east to the existing drrh;;;;;iet*een lot I and 5. A newdrainage ditch was constructed across tot t torn"wrriio east, this refers to ditch c.

Ditch c is approximately 5 to7 feet in depth and 4 to 5 feet in width. Ditch B runsparallel with colorado State Highway.J21.il;;ft#yiirr"tioo and averages 2 feetdeep and 2 feetwide (refer to pf,oto it1 oit"t, A ;.il* easterly direction arong theborder between lots r and 6. @efer r9.plr"t9 ? *";i; percoration pits have beenconstructed on the property, which wili be nilla "t-trr"";" time the ditches arebackfilled @efer to photo-t3).
The vegetation on Lots I and 6 includedJune grass, slenderwheatgrass, sheep fescue,Arizona fescue, milkweed, juncus, *rl or_di"nrrr'., *d Nebraska Sedge. Thisvegetation is limited to Lots I and6 of ttre six#;"pr.ty'except along Rifle creek and asmall drainage way on l-ot Z.
The drain ditches were constnrcted through a sedge and rush wetland, which includeshydric soil, saturation to the surface fu iq"".*" rrg;rtion. @efer to photos 7, rs,16' and 17') This area Pre-excavation n"i-" rrvoifu.-i#lethat produced a high levelof soil saturation' Ttreie ditches drastically
"ir^*sJ?"-rr'va."r.sic regime of the sillsproperty' By allowing a substantial amount of griund *ui., that had previously saturatedthe soil to drain into these ditches, the excavation has mutated the dynamic hydrologythat once existed in T: area. Yeiby observinjA;;.tuJregeneration that iras arreadyoccurred in the affected axeas we beiieve the p6tentia ror Lstoration success is high.
Goals and Objectives
The goals and objectives ofBeach Environmental are to restore the impacted weland bybackfilling the existing excavated ditch areas with the same materials dredged from theditches' which materials remain on the property. Beach Environmental intends tomonitor this process in order to make sureitraitrr" nr.r.r*y amount of soil compactionoccurs' thus reducing the potential for t"atage arounJflrriilr.nrt materiJuoig with re-developing natural hvdroltgic conditions. Backfi ltn! ;ifi;6-;;;##;originalhydrologic regime in the area, and trrtor. the weflan& to a self-sustaining condition.Beach Environmental also proposes to ie-vegetate the area with vegetation existing onsitein order to reduce the potenti"t ror introducti6n ornon*"tive species.i
o Mitieation Work Plan
This proposed restoration plan involves work on lots I and 6 of the Sills property only.
lhis plan proposes thalth9 first step of the restoration process will be "o*pt"t, with thefilling of the drainage ditches A and B and a partial ndaitctr C. Dredgea *"toirt to,,these ditches has been placed into wetland ,rc", on lots I and 6 but thI depth and cover isminimal and re-growth of Nebraska sedge and Butush is already o""uoini (rrfer tophotos 1,4,11).
t" plT contemplates careful removal of all dredged materials back into the ditches toeffect the natural reclamation of a portion of the iripacted lands. By r;idth" arragrAmaterial found onsite as backfill material we are using soil that has the same levels ofporosity, organic material, texture and taxonomy. Thi use of onsite fill will reduce thechance of seepage into the fifl material occupying the pre-existing ditch bed.
Beach Environmental also proposes to install curtain dams along the path of the ditch atnecessary intervals to eliminate the drains altogether. These curtain dams will be theonly stnrctural hydrologic control structures urid in the project and require
"o r.rt ,,"maintenance.
Thi,s lack of engineered sbuctures in the wetland's restoration plan allows the landscapeto develop on its own once the initial work is finished. It is also proposed that vegetationimpacts will be addressedard mitigated by the harvesting of plugs from existingundisturbed sedge and rush wetland areas on Lots l and 6.
As mentioned above such practices that consider that insular ecological landscape willexpedite the remediation process and reduce the potential for the intoduction ofnon-native species. It is also proposed that nrrsery stbck be purchased from RockyMountainNative Plants in Rifle to restore areas where natural regeneration and transplanting hasnot been successful.
A wetland specialist from Beach Environmental will direct the restoration work and willmark species and individual plants for harvesting and replanting. Beach Environmentalwill also stake the location.of nursery stock installation. Since seeding is not beingproposed and much of.$? impacted plants are in early states of regeniation, and flugs ofmature native plants will be used to re-vegetate fill areas.
The use of mulch is not anticipated or proposed. However, should seeding be warranted,
a certified weed free straw mulch will be used with an appiication rate of ipproxim ately1.5 tons per acre of coverage
Performance Standards
Beach Environmental-will ?ft* to all perfonnance standards set by the Army Corps ofEngineers and we will employ adaptive management techniques to our restorationo
o proposal in order to adjust to unforeseen or changing circumstances. The monitoring plandescribed below uses an adaptive performance approach.
Project Success
The parties responsible for the success olthis project include Beach Environmental andMr' Mark Sills' Mr' sills will be responsiblr glirrri"gl contract to complete theexcavation work and Beach Environmental will ou"rr.i all restoration work. The workwill be completed under.the authority.ortrre u.s. ermv iorp, of Engineers and does notappear to require a permit for restoratlol conerporarr., between the project Managerfor the uS Army c.orpf of Engineers, Mr. Mark Aifilil;and Mr. Beach, indicares thatMr. Sills.can completely restore all impacts to his property without any required Corpspermits. (See attached copy of correspondence.)
I r ---'
Site Protection
Mark and Patrici".lit} own the property to be restored by Beach Environmental. BeachEnvironmental will take all necessary piecautions duringrestoration to ensure thatadditional lands are not negatively impacted.
Contineency Plan
Due to the comprehensive evaluations completed as part of this plan, the soil t5pes,hvdrologv and vegetative materials have ali been in*rtori.Jffi il Jrirri#tl of theplan negates the need for additional contingen"V pf*r.
----
Digital Photographs of the site have been taken which depict the general condition of theproperty' These photos are included as an attachment to ihis rep;. aaaiti"""rphotographs will be taken prior to restoration torn rpr.ffir locations and particular viewplanes' The photographs will be used to document trrr *oir. completed to restore theimpacted wetlands and to establish a baseline for monitoring ttre success of remediationthe drains, and revegetating the site. Monitoring wittoccur during the mid-point of thetwo growing seasons following completion of ti'e restoratin. At the end of the secondgrowing season a monitoring report will be filed with trr" u.s. Army corps of Engineersquantising the vegetation survival and restoration plan,s success.
Financial Assurances
Mr' Sills is financially responsible for the restoration of wetlands upon lots 1 and 6 of theSills proposed Creekside Estates property.

Wetland Delineation on Sills property, Rifle, Co
e
on 6/8 and 619' 2004 Bio-Environs performed a routine wetland delineation according to the I9g7Arniy corps of Engineers wetland dilineation manualat section Ig,Tss, Rg2w, on Mark Sills,property ln Rifle, co'(Fig' l). The request for this p"rti;;;;lineation stems from possibleviolations with regards to trenching *d ,o*" overland grading. in addition, the property ownerwishes to apply fot a 404 permit tJ access the proposed"dw"rip-*, of the land. This proposeddevelopment is referred to as Creekside Estates.
Site description
The l5 acre site includes on its east boundary Rifle cree( and the associated riparian wetland.Rifle creek has cut banks and a very small floodplain supporting various grass species. Thewestern poltion of the property supports what appears to be a spring-fed trenched wetlands. In thesouthern portion of the area there is an existing arir"*"v.rJ"l.""rr creek or drainage whichsupports a minimal wetlands along flowing waters. Two ponds sit directly north and south of thedriveway' apparently acting "t ""I"h..rt] Along the eastern side of the property is a residence.The land near the house has been gaded. sod and an irrigation system have been installed aroundthe house' The eastern area also slupports pasture which appears to have been seeded with wheatgrass' There is a spring area located southwest ofthe house. It is near a natural drainagg but
$rt"I::.n"r"
arso been created around it. visibre g;;il;r;iin., pot.nti"r roads for crikside
Merhodology
The wetland delineation involved identifuing the wetland boundary using pin flags and flagging.Data forms have beenpr"plfd for every tJnth point of the delin-ition boundary. The flags arenumbered in sequence from #l on the rolrth".rt edge of Rifle c..rt to #99 atthe confluence of theaforementioned drainage and Rifle creek. More iriportarrly,;t;;."1 data forms were preparedfor areas affected by trench^ingor graoint. ino. uro, ur.ia.nii'nro uy points 36_39,4042,43_50, 5l-59, 59-60, 70,76-79, to-tq. sotmaps (Fig. 2) and aeriar photos (Fig. 3) were obtained toaid in the delineation' The soil survey *rp *u, completed in 1972. The color aerial photo wasflown in r 999' Evidence ofrand *a,iputojtion is apparent i, ,n" *riur ptotor.
Results
Rifle creek is a riverine, Iower perennial, unconsolidated bottom wetland according to cowardin etal' (1979) that has been influenced by the creation of Rifle Gap Reservoir. The reservoir isapproximately 5 miles upstream. The effective discharge ani lanrfull flow of Rifle creek hasdecreased' revealing cut banks and the formation of a liwer Rooo plain a-djacent to the creek. Theremaining wetlands are palustrine, emergent with varying levets orrrydrolory as a result oftrenching and grading.
Vegetation
The vegetation adjacent to Rifle creek includes common reed grass (phragmites australis), andreed canary gtass (Phalaroides arundinacea),bothof which aie iocated on tne lower floodplain.Greasewood (sorcobatus vermiculatus) was growing on top of the cutbanks of the creek. Alder(Alnus tucantenfolia) and boxelder (Aier negundo) were found on the creek bank in the southeastcorner-of the property' The vegetation in the western portion ortr,. proprrty consisted of Arcticrush (Juncus articus), sedge (Carex praegracilis),
"nd
in the wetter areas three square bull rush(shoeltopl.ectw pungeng and spikerusn (neocltarx orirririri. The vegetation in the areaassociated with the drainage in the southern portion of the site included Arctic rush(Muhlenbergia asperifolia) ard foxtail (Hordeum jubatum). To the east of the trench that runsnorth - south, Arctic rush.grades into upland wheat"grasser.' rrr" wetlands in this area are obscureas there is no wetland hydrorogy pr"r"rrt, but at onetime hydrophytic prant species may havedominated' The ditches
".ourd tir" spring area south and west ofthe house support cattail (Typhalatifolia)' (Muhlenbergia asperdolia), arnd varioul*oay rpoies. To the cenier of the springarea' the ground rises and supports wheatgrasses. This siring has been ditched at its edges.
Soils
According to the soil conservation survey (1g72)maps the entire property is within theHaloquept soil type. Haloquept soils are poorly drainei and alkaline in nature. The water tabte isat or near the surface mainJy in spring ,nd ,rm*er. Typicalry, the soils were found to show acolor of l0 YR3/2 with mottles. soni" oxidized rr,i^rp't"ro *.r. p.o*,. The soils along thecreek were also l0 yR3/2 with mottles. The western p"ni", *noinro a sandy soil with organicstreaking and some mottled layering. In the drainage area to the south we found the soils gleyedwjth organic streaking' This was Jso the case in tfie ditches near the spring. The soils to the eastof the trench were found to be dry but showed a chroma that would suggest a hydric soil.
Hydrolory
Besides some overland grading, the most prevalent impact to the wetlands on this property istrenching' The trenches are located at the northwest ana midsection of the property. These wereestablished 18 months ago and have served to dry portions of ttre wet areas. The trench in thenorth is 8-10 ft' deep' other trenches are24ft. deep, ,or".oit"ining flowing water. The onlyplaces wetland hydrolog exists are the northwest.* .o-r., ii. Jir.rro, the trenches, Rifle creekand the spring area' several test pits not associated with;i, f;;'*".e dug; there was no standingwater, only moist conditions. However, the soir chroma aia inal"t, a hydric soir.

RE: Regional Permit Verification-Creek Side Estates Subdivision-
Dear Mark:
I appreciated the opportunity to meet you onsite at the Creek Side Estates, also known as the
Sills Property, to verify the extent ofjurisdictional wetlands. Based on our meeting, I have
reconfigured the proposed subdivision to avoid these wetlands when possible and to minimize
the impacts where avoidance was not possible. Therefore I am requesting a verification of a
Nationwide Permit for the proposed redevelopment. The applicant and agent for these permits
are:

As you know, Creek Side Estates is located in Section 19, Township 5 South, Range 92 West
ofthe Sixth Principal Meridian, Garfield County, Colorado. The property is further located
along State Highway 325, approximately 4.5 miles north of Rifle in Garfield County,
Colorado, and is comprised of approximately 15.37 acres. The subject property contains an
existing single-family residence, a driveway and supportive utilities. Please see the attached
Vicinity Map.
Jurisdictional wetlands within Creek Side Estates were recently delineated by Bio-Environs
and submitted to the USACE in a letter dated June 15, 2004. As you know, the owner is
cnrrently working on a Voluntary Wetlands Restoration Plan @ermit #200275435) which
will be completed by August 10, 2004. The Applicant is now requesting a permit to
redevelop the property for six (6) single-family residences and new roads with shallow utility
-improvements: -?reliminary Plan drawings depicting the proposed improvements havebeen
included with this application.
923 Cooper Avenue I Suite 102 | Glenwood Springs I Colorado 81601 I Ph 97O.945.5252 | Fax 970.384.2A33
A Nationwide Permit #14, 'Linear Transportation Projects', is requested for the construction
of the new subdivision access road with public utilities (in the roadway) from the State
Highway 325 right-of-way. The purpose for this new access road is to comply with the
Colorado Department of Transportation State Highway Access Code under Permit #303048,
Application #02-149. The existing access from State Highway 325 is located near the
southwest comer of the property at a point where the minimum stopping sight distance
cannot be obtained due to the curvature of the existing roadway and natural features.
Therefore, CDOT has required that this access be replaced in conjunction with the proposed
redevelopment. I have attached a copy of the validated State Highway Access Permit for
your review. To minimize impacts, the proposed roadway has been designed to meet
minimum width standards and utilities have been proposed within the roadway rather than
along the edge as is typical. Garfield County Subdivision Regulations for this subdivision
require a minimum roadway containing 2-8' travel lanes with 2' shoulders and a morimum
cul-de-sac length of 600' with a 45' radius turnaround. The roadway design was aligned to
get out of the wetlands and back onto the existing roadway platform at the nearest location
and roadway grades were maximized. Conformance to this criteria results in an affected
jurisdictional wetland area of approximately 0.486 acres. Jurisdictional wetlands adjacent to
the proposed earthwork will be lined with sediment control fencing prior to excavation.
Lost wetlands will be offset through the expansion of overland flow waters near the north
boundary and widening of the existing drainage charurel along the south boundary. A
shallow 6" deep swale will be extended from the existing central channel to improve
overland flows and induce the hydrologic soil character in an 18,000 SF area on land
northeast of the existing jurisdictional wetlands. The bottom width of the south drainage
channel will be expanded and 6"-t2" berms installed to create a gently sloping basin
containing 3,200 SF of additional wetland area. Both of these areas will be seeded with a
native wetland seed mixture prepared by a local landscape professional such as Rocky
Mountain Native Plants.
To conclude, the proposed redevelopment will also contain platted building envelopes and
deed restricted areas to maintain development outside the eiisting and proposed
jurisdictional wetlands. No fill will be placed within the delineated wetlands to support any
funre residences, out-buildings or septic systems. If you have any questions or comments,
please feel free to call me at (970) 945-5252.
Sincerely,
Deric J. Walter, P.E.
