PROPOSAL:A Major Subdivision Preliminary Plat application proposal to subdivide 106.8 +/-acres
into Twenty One (21)residential lots.The average lot size will be 5.00 +/-acres in the Rural Zone.The
lots will share a private subdivision road “Yellow Star Road”off of Prater Canyon CR 116.Each lot will
have individual wells,and individual engineered-enhanced septic systems permitted directly through
Wyoming Department of Environmental Quality.
The site is surrounded by agricultural uses with the exception of a residential home to the southeast and
southwest.The new proposed subdivision roads will require a 24’travelway with 1’shoulders and a 70’
radius cul de sac.
LOCATION:1.6 miles west of the Town of Star Valley Ranch,Wyoming in Section 26,Township 35
North,Range 119 West.

BACKGROUND:
This major subdivision is three landowners that own approximately 35 acres each,and have come
together to create one major subdivision of 21 lots averaging 5 acres each.The landowners have joined
together on their Chapter 23 Water and Sewer study,and will work together on road construction and road
maintenance.
The main access is from Prater Canyon County Road 12-116 and will connect to the property to the North
which is a new subdivision “Etna Ranch”that is in the permitting process.The road will be designed to
connect CR 115 with CR 116 through the two subdivisions.
A Traffic Study was requested by planning staff due to five major proposed subdivisions in one
geographical area.The traffic study is 300+pages and available upon request.Planning Staff has
reviewed the traffic study and do not find reasons this subdivision should not have a recommendation of
108-MA-23
PZC -Preliminary Plat
Preliminary Platapproval.The result of the traffic study determined that if all five developments are approved and built
out by the year 2035,a signal would be recommended where CR-115 &CR-116 meet HWY 89.
The site does have some topography issues,and planning staff has requested an engineered road design to
confirm the road will meet county standards.
Planning Staff is attempting to resolve some future connectivity concerns.
Chapter 5.2 Preliminary Plat Drawings and Plans I.2.Access points to subdivision,including connections
to adjoining subdivisions,and County and State roads;
There are some concerns by Planning Staff for future connectivity,and the need for a second entrance to
comply with the International Fire Code.Staff has requested conditions of approval for reciprocal
easements to the property to the north and for the road to connect to CR 115 prior to Final Plat.
Planning Staff also recognizes an access concern for the neighbor to the southwest.Due to the location of
the subdivision road meeting CR 116,the southwest neighbor's only point of access is adjacent to the
subdivision road access point.Planning Staff will not recommend another County Driveway Access
Permit so close to the subdivision access point.Therefore creating the subdivision road will hinder the
neighbors future access.Planning Staff has recommended a condition of approval that a 60’easement be
granted to the neighbor for the first 750’of the subdivision road.The reason for this length of easement is
to eliminate having a long driveway paralleling too closely to the subdivision road,this will avoid future
issues like snow removal overlapping.
There is a parcel of 36 acres that currently has an easement over these lands,that the developer will be
trading for a new easement over the subdivision road.Planning staff requested a condition of approval
that this easement be granted to avoid potential issues with the old easements.
AGENCY CORRESPONDENCE:
Lincoln County Weed &Pest:At time of inspection,Black Henbane &Hounds Tonge were present,a
Weed Management Plan is required by the Development Agreement to prevent these noxious weeds from
propagating freely.
Star Valley Conservation District:“The property has had a Water and Wastewater System Study
performed by Sunrise Engineering.Any recommendations in the study supersede any
recommendations in this report.”
Due to a large variation of water levels in this section,SVCD recommends soil cuts to determine
groundwater levels.If ground water is high,we recommend an enhanced septic system.We
STRONGLY RECOMMEND that soil cuts be taken in the spring/early summer when
groundwater is highest.If soil cuts are done at other times know that static water level can
fluctuate according to the amount of high-water runoff from year to year.
The East Side Canal with water from the Salt River runs through the entirety of this subdivision.
Lots located on the west side of the East Side Canal include water rights.Lots on the west side of
108-MA-23
PZC -Preliminary Plat
Preliminary Platsaidcanalhavenowaterrightsincluded.The East Side Canal District must have maintenance
access to the canal.SVCD highly recommends that no landscaping,such as shrubbery and trees,
etc.,be placed within fifteen feet of either side of said canal.For questions regarding this please
contact Jared Jenkins,watermaster,at 307-690-2221.
State Engineer's Office:Our records indicate that there may be some irrigated acres associated with the
subdivision lands under Permit P1266.0E.These acres need to be addressed per Statute.See item 7 for a
summary of our findings and the processes to address these acres per Statute.
Wyoming DEQ:DEQ provided a non-adverse recommendation with Enhanced and Engineered Septic
Systems and individual water wells are safe and adequate for the Alpenglow Subdivision.DEQ
Recommend a Plat Warning with the following text:

P. O. Box 468
Kemmerer, WY 83101 STAR VALLEY CONSERVATION DISTRICT Board of Supervisors has reviewed the proposed GT Urie-Gary Nix, major subdivision east of Thayne, Wyoming and southwest of Star Valley
Ranch, Wyoming. This subdivision is part of a master plan that will eventually include 21 lots.
The property has had a Water and Wastewater System Study performed by Sunrise Engineering. Any recommendations in the study supersede any recommendations in this report.
Due to a large variation of water levels in this section, SVCD recommends soil cuts to determine groundwater levels. If ground water is high, we recommend an enhanced septic system. We STRONGLY RECOMMEND that soil cuts be taken in the spring/early summer when groundwater is highest. If soil cuts are done at other times know that static water level can
fluctuate according to the amount of high-water runoff from year to year.
The East Side Canal with water from the Salt River runs through the entirety of this subdivision. Lots located on the west side of the East Side Canal include water rights. Lots on the west side of said canal have no water rights included. The East Side Canal District must have maintenance
access to the canal. SVCD highly recommends that no landscaping, such as shrubbery and trees,
etc., be placed within fifteen feet of either side of said canal. For questions regarding this please contact Jared Jenkins, watermaster, at 307-690-2221. Please note the items in the Lincoln County Weed and Pest report that need to be addressed.
This report satisfies the Conservation District Review as required by Wyoming State Statute 18-5-306. No other use is intended or implied. If there is any more information we can provide for you, please let us know.
Yours truly,
STAR VALLEY CONSERVATION DISTRICT
Rollin Gardner Chairman
Subdivision Review GT Urie-Gary Nix Major Subdivision
Thayne, Wyoming November 29, 2022 Location The GT Urie-Gary Nix major subdivision is in the SE1/4 NW1/4 and the E1/2SW1/4 of Section
26 T35 R119W, west of Star Valley Ranch, Wyoming. The proposed subdivision is +/- 35 acres
and will be divided into 7 lots. This subdivision is part of a master plan that will eventually include 21 lots. Water
Star Valley Conservation District (SVCD) personnel used the State Engineers Water Rights Data
Base to obtain groundwater information for this property. Well logs from wells in the vicinity indicated the static water level is between 6 and 140 feet below ground surface. The property has had a Water and Wastewater System Study performed by Sunrise
Engineering. Any recommendations in the study supersede any recommendations in this report. The East Side Canal with water from the Salt River runs through the entirety of this subdivision. The lots on the west side of the East Side Canal include water rights. The lots on
the east side of said canal have no water rights. The East Side Canal District must have maintenance access to the canal. SVCD highly recommends that no landscaping, such as shrubbery and trees, etc., be placed within fifteen feet of either side of said canal. For questions regarding this please contact Water Master, Jared Jenkins, at 307-690-2221.
Salt River The Salt River is listed on Table C (Water Bodies with Water Quality Threats) of the Wyoming Department of Environmental Quality (WDEQ) 2020 Section 303(d) List. The Salt River does not support the designated use for contact recreation use due to elevated levels of fecal coliform
bacteria.
In response to this listing, the Star Valley Conservation District (SVCD) initiated watershed-planning activities for the Salt River Watershed in 2003. The Salt River Watershed Plan has been completed, was formally submitted to WDEQ and was accepted and signed by WDEQ in July 2005. SVCD completed a TMDL for the Salt River in 2016 which was submitted to WDEQ.
SVCD continues to monitor the watershed. We have collaborated with landowners to implement
fencing and off stream watering for livestock. We also provide a cost share to homeowners to pump septic systems after attending our septic workshops.
The Salt River Watershed Plan identifies rural subdivisions as adversely affecting water quality in the Salt River Watershed. Storm water run-off from this subdivision should be managed using
best management practices to ensure that pollutants such as storm water runoff, animal wastes,
sediment, and fertilizers do not reach the irrigation ditches or other surface waters in the area.
National Pollutant Discharge Elimination System (NPDES)
The Wyoming Department of Environmental Quality (WYDEQ) requires all construction sites that disturb 1 acre or more to have a construction NPDES permit. The areas do not have to be contiguous. The permit requires construction site operators to implement appropriate erosion and sediment control best management practices, control waste such as discarded building materials,
concrete truck wash-out, chemicals, litter, and sanitary wastes.
Operators of construction activities must develop a Storm Water Pollution Prevention Plan (SWPPP) that describes the measures to be implemented at the construction site that will eliminate or minimize pollutants from the project from reaching surface waters.
The terms and conditions of the permit must be implemented until the land disturbed by construction activities has been ‘finally stabilized.’ Finally stabilized is defined as “all soil disturbing activities at the site have been completed, and a uniform perennial vegetative cover with a density of 70% of the native background vegetative cover for the area has been
established on all disturbed unpaved areas and areas not covered by permanent structures”.
If construction will disturb 5 or more acres a stormwater permit from WYDEQ is required. For more information regarding the NPDES requirements please contact Katy Sprouse by phone or
email at 307-777-7570 (katysprouse@wyo.gove)Anita Rehner, WYDEQ Program Coordinator at
307-777-5622 or (arehner@state.wy.us).
Soils The following soils information provided by the Natural Resources Conservation Service (NRCS)
Soil Survey of Star Valley Area, Wyoming – Idaho. This information does not eliminate the need
for onsite investigation of the soils or for testing and analysis of these soils by a Wyoming Licensed Engineer experienced in the design and construction of engineering work. The proposed subdivision is comprised of 4 soil types identified as Robana Silt loam 3 to 10 percent
slopes (RoC), Robana Silt Loam 10 to 20 percent slopes (RoD), Willow Creek-Bozeman association,
undulating (WcC), Willow Creek-Bozeman association, hilly (WcD). You can see each of these areas clearly marked on the soils map, provided separately in this report. Limitations: ‘not limited’ indicates that the soil has features that are favorable for the specified
use, good performance and very low maintenance can be expected. ‘Somewhat limited’
indicates that the soil has features that are moderately favorable for the specified use. The limitations can be overcome or minimized by special planning, design, and installation. Fair performance and moderate maintenance can be expected. Soils with ‘very limited’ designations indicate that the soil has one or more features that are unfavorable for the specified use. The
limitations generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures, poor performance and high maintenance can be expected. Dwelling with and without basements: The degree of limitations for dwellings with and without basements in areas For areas containing Robana silt loam 3 to 10 percent slope (RoC) the
rating is Somewhat Limited due to shrink-swell. Areas containing Robana Silt Loam 10 to20
percent slopes (RoD) are rated as Very Limited due to slope and shrink-swell. Dwellings without basements in areas containing Willow Creek-Bozeman association, undulating (WcC), are rated as Somewhat Limited due to shrink-swell. Dwellings with basements in these areas are rated as Not limited. Dwellings with and without basements in areas containing Willow Creek-Bozeman
association, hilly (WcD), are rated as Very Limited due to slope and shrink-swell.
Soil cuts were not conducted as part of this review. Care should be taken not to locate buildings in the intermittent drainage or any drainage channel where overland flooding could occur during early spring snowmelt or heavy thunderstorms. Sewage Disposal: The degree of limitations for septic tank absorption fields in areas containing Robana silt loam 3 to 10 percent slopes (RoC) are rated as Somewhat Limited due to slow water movement. Areas containing Robana silt loam 10 to 20 percent slopes (RoD) are rated as Very Limited due to slope and slow water movement. Areas containing Willow Creek-Bozeman
association, undulating (WcC) are rated as Somewhat Limited due to slow water movement. Areas
containing Willow Creek-Bozeman association, hilly (WcD) are rated as Very Limited due to slope and slow water movement. Roads and streets: The degree of limitations for roads and streets for areas containing Robana
silt loam 3 to 10 percent slope (RoC), Robana silt loam 10 to 20 percent slope (RoD), and Willow
Creek-Bozeman association, undulating (WcC) are rated as Very Limited due to frost action, slope, low strength, and shrink-swell. Areas containing Willow Creek-Bozeman association, hilly (WcD)are rated as Very Limited due to frost action, low strength, and shrink-swell and slope.
Shallow excavations: The degree of limitations for shallow excavations in areas containing
Robana silt loam 3 to 10 percent slope (RoC) and Willow Creek-Bozeman association, undulating (WcC) is rated as Somewhat Limited due to cutbanks cave. Areas containing the Robana silt loam 10 to 20 percent slopes (RoD), and Willow Creek-Bozeman association, undulating (WcD) is rated as Very Limited due to slope and cutbanks cave.
Erosion Hazard: The potential of erosion hazard for unsurfaced roads and trails for areas containing Robana Silt loam 3 to 10 percent slope (RoC) and the Willow Creek-Bozeman association, undulating (WcC) the rating is listed as Moderate due to slope/erodibility. For the areas containing the Robana silt loam 10 to 20 percent slope (RoD) and the Willow Creek-
Bozeman association, hilly (WcD) are both rated at Severe due to slope/erodibility.
The potential erosion hazard of construction sites for areas containing the Robana silt loam 3 to 10 percent slope (RoC) and the Willow Creek-Bozeman association, undulating (WcC) the rating is listed at Moderate due to slope/erodibility. For a areas containing the Robana silt loam
10 to 20d percent slope (RoD) and the Willow Creek-Bozeman association, hilly (WcD) the
rating is listed as Severe due to slope and erodibility. To avoid potential erosion or sedimentation problems all disturbed areas during subdivision construction, especially road banks, need to be mulched and seeded back to adapted
grass/legumes and tress/shrubs as soon as possible. Topsoil should be stockpiled and saved
during construction, so adequate seedbeds can be prepared in the disturbed areas. Appropriate erosion and sediment control best management practices should be installed and maintained for the duration of the project.
Noxious Weeds
Lincoln County Weed and Pest report is included separately in this report. Please note the presence
of Black Henbane and Hounds Tongue. It is requested that the subdivision owners contact Lincoln County Weed and Pest to explain their weed control strategy. Lincoln County Weed & Pest furnishes herbicides for noxious weed control at a discount to
landowners. Check with Weed and Pest to see if you qualify. They also offer ATV sprayers and
25-gallon pickup sprayers for rent. All visits to the property as well as any consultations are at no charge. To contact Lincoln County Weed and Pest call 307-885-9333 (WEED). Small Acreage Grazing/Livestock Management Please be aware, grazing animals on small acreages can have a significant impact on the condition of soil, water, plants, and other natural resources. Care should be taken to ensure agricultural activities such as grazing, corrals, pastures, feedlots,
animal waste storage or spreading does not take place within any wellhead protection zone. Best management practices should be implemented on these parcels to ensure animal wastes does not reach spring or Salt River during times of high water, snow melt, or storm run-off. This can be done by using berms, filters strips, grassed swales and catch ponds. The SVCD recommends the
individual lot owners obtain a site-specific grazing and waste management conservation plan from the local Natural Resources Conservation Service office in Afton. The plans are provided free of charge. For more information, please contact Adam Clark, 307-886-9001 ext.109, adam.p.clark@usda.gov.
Wildfire and Landscaping: Wildfire is possible in this area. Well planned landscaping can reduce wildfire danger. The home should have a defensible space. SVCD recommends
following the guidelines in the University of Wyoming Barnyards and Backyards Living with
Wildfire in Wyoming publication.
http://www.uwyo.edu/barnbackyard/_files/documents/resources/wildfire2013/wildfire_web.pdf
Wildlife Friendly Fencing Fences cause the direct mortality of wildlife through entanglement and prohibition of movement
to seasonal ranges. Fences constructed or currently in existence on the property should be
designed to allow free and unrestricted movement of wildlife. Wyoming Game and Fish Department recommends fences be built to minimally restrict livestock and horses, while allowing free movement of wildlife (e.g. a smooth bottom wire 16-18 inches above ground, a 39- inch maximum height and at least 12 inches between the top two wires). Wildlife can benefit from
any area of open space. For more information please see Fencing Guidelines for Wildlife
Wyoming Game & Fish Habitat Extension Bulletin No. 53 at the Wyoming Game and Fish website http://gf.state.wy.us/downloads/pdf/habitat/Bulletin%20No.%2053.pdf.
Homeowners should protect ornamental shrubs used for landscaping and future homeowners
should know that, by state statute, the Wyoming Game and Fish Department is not liable for
damage caused to ornamental plants by wildlife.
The potential exists for wildlife conflicts, especially between wildlife and free-ranging domestic
pets. The landowner should take precautions to minimize harassment of wildlife by dogs and cats.
It is illegal to allow pets to chase or kill wildlife. Likewise, rural landowners should recognize that black bears, mountain lions, and other carnivores may come near their dwellings and may pose a threat to pets allowed to range freely.

Dwellings and Small Commercial Buildings
Soil properties influence the development of building sites, including the selection of the site, the design of the structure, construction, performance
after construction, and maintenance. This table shows the degree and kind of soil limitations that affect dwellings and small commercial buildings.
The ratings in the table are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features
that affect building site development. "Not limited" indicates that the soil has features that are very favorable for the specified use. Good performance
and very low maintenance can be expected. "Somewhat limited" indicates that the soil has features that are moderately favorable for the specified
use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be
expected. "Very limited" indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be
overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be
expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00.
They indicate gradations between the point at which a soil feature has the greatest negative impact on the use (1.00) and the point at which the soil
feature is not a limitation (0.00).
"Dwellings" are single-family houses of three stories or less. For dwellings without basements, the foundation is assumed to consist of spread
footings of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth of maximum frost penetration, whichever is deeper. For
dwellings with basements, the foundation is assumed to consist of spread footings of reinforced concrete built on undisturbed soil at a depth of about
7 feet. The ratings for dwellings are based on the soil properties that affect the capacity of the soil to support a load without movement and on the
properties that affect excavation and construction costs. The properties that affect the load-supporting capacity include depth to a water table,
ponding, flooding, subsidence, linear extensibility (shrink-swell potential), and compressibility. Compressibility is inferred from the Unified
classification. The properties that affect the ease and amount of excavation include depth to a water table, ponding, flooding, slope, depth to bedrock
or a cemented pan, hardness of bedrock or a cemented pan, and the amount and size of rock fragments.
"Small commercial buildings" are structures that are less than three stories high and do not have basements. The foundation is assumed to consist
of spread footings of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth of maximum frost penetration, whichever is
deeper. The ratings are based on the soil properties that affect the capacity of the soil to support a load without movement and on the properties that
affect excavation and construction costs. The properties that affect the load-supporting capacity include depth to a water table, ponding, flooding,
subsidence, linear extensibility (shrink-swell potential), and compressibility (which is inferred from the Unified classification). The properties that affect
the ease and amount of excavation include flooding, depth to a water table, ponding, slope, depth to bedrock or a cemented pan, hardness of bedrock
or a cemented pan, and the amount and size of rock fragments.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design
and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil
between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a
specific soil.

This table shows the degree and kind of soil limitations that affect septic tank absorption fields and sewage
lagoons. The ratings are both verbal and numerical. Rating class terms indicate the extent to which the soils are
limited by all of the soil features that affect these uses. "Not limited" indicates that the soil has features that are
very favorable for the specified use. Good performance and very low maintenance can be expected. "Somewhat
limited" indicates that the soil has features that are moderately favorable for the specified use. The limitations can
be overcome or minimized by special planning, design, or installation. Fair performance and moderate
maintenance can be expected. "Very limited" indicates that the soil has one or more features that are unfavorable
for the specified use. The limitations generally cannot be overcome without major soil reclamation, special design,
or expensive installation procedures. Poor performance and high maintenance can be expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal
fractions ranging from 0.01 to 1.00. They indicate gradations between the point at which a soil feature has the
greatest negative impact on the use (1.00) and the point at which the soil feature is not a limitation (0.00).
"Septic tank absorption fields" are areas in which effluent from a septic tank is distributed into the soil through
subsurface tiles or perforated pipe. Only that part of the soil between depths of 24 and 60 inches is evaluated.
The ratings are based on the soil properties that affect absorption of the effluent, construction and maintenance of
the system, and public health. Saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to
bedrock or a cemented pan, and flooding affect absorption of the effluent. Stones and boulders, ice, and bedrock
or a cemented pan interfere with installation. Subsidence interferes with installation and maintenance. Excessive
slope may cause lateral seepage and surfacing of the effluent in downslope areas.
Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below
the distribution lines. In these soils the absorption field may not adequately filter the effluent, particularly when the
system is new. As a result, the ground water may become contaminated.
"Sewage lagoons" are shallow ponds constructed to hold sewage while aerobic bacteria decompose the solid
and liquid wastes. Lagoons should have a nearly level floor surrounded by cut slopes or embankments of
compacted soil. Nearly impervious soil material for the lagoon floor and sides is required to minimize seepage and
contamination of ground water. Considered in the ratings are slope, Ksat, depth to a water table, ponding, depth
to bedrock or a cemented pan, flooding, large stones, and content of organic matter.
Ksat is a critical property affecting the suitability for sewage lagoons. Most porous soils eventually become
sealed when they are used as sites for sewage lagoons. Until sealing occurs, however, the hazard of pollution is
severe. Soils that have a Ksat rate of more than 14 micrometers per second are too porous for the proper
functioning of sewage lagoons. In these soils, seepage of the effluent can result in contamination of the ground
water. Ground-water contamination is also a hazard if fractured bedrock is within a depth of 40 inches, if the water
table is high enough to raise the level of sewage in the lagoon, or if floodwater overtops the lagoon.
A high content of organic matter is detrimental to proper functioning of the lagoon because it inhibits aerobic
activity. Slope, bedrock, and cemented pans can cause construction problems, and large stones can hinder
compaction of the lagoon floor. If the lagoon is to be uniformly deep throughout, the slope must be gentle enough
and the soil material must be thick enough over bedrock or a cemented pan to make land smoothing practical.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning
site investigations prior to design and construction. The information, however, has limitations. For example,
estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7
feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a
specific soil.
The information is not site specific and does not eliminate the need for onsite investigation of the soils or for
testing and analysis by personnel experienced in the design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose specific design criteria were
not considered in preparing the information in this table. Local ordinances and regulations should be considered in
planning, in site selection, and in design.

Erosion Hazard of Natural Surface Roads and Construction Sites
This table can help land owners or land users plan the use of soils for unpaved roads. Interpretive ratings are
given for the soils according to the limitations that affect unpaved roads. The ratings are both verbal and
numerical. Some rating class terms indicate the degree to which the soils are suited to a specified practice. Well
suited indicates that the soil has features that are favorable for the specified practice and has no limitations. Good
performance can be expected, and little or no maintenance is needed. Moderately suited indicates that the soil
has features that are moderately favorable for the specified practice. One or more soil properties are less than
desirable, and fair performance can be expected. Some maintenance is needed. Poorly suited indicates that the
soil has one or more properties that are unfavorable for the specified practice. Overcoming the unfavorable
properties requires special design, extra maintenance, and costly alteration. Unsuited indicates that the expected
performance of the soil is unacceptable for the specified practice or that extreme measures are needed to
overcome the undesirable soil properties. Numerical ratings in the table indicate the severity of individual
limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the specified practice (1.00) and the
point at which the soil feature is not a limitation (0.00). The paragraphs that follow indicate the soil properties
considered in rating the soils for forest management practices. More detailed information about the criteria used in
the ratings is available in the "National Forestry Manual," which is available in local offices of the Natural
Resources Conservation Service or on the Internet. Ratings in the column hazard of off-road or off-trail erosion
are based on slope and on soil erodibility factor K. The soil loss is caused by sheet or rill erosion in off-road or off-
trail areas where 50 to 75 percent of the surface has been exposed by logging, grazing, mining, or other kinds of
disturbance. The hazard is described as slight, moderate, severe, or very severe. A rating of slight indicates that
erosion is unlikely under ordinary climatic conditions; moderate indicates that some erosion is likely and that
erosion-control measures may be needed; severe indicates that erosion is very likely and that erosion-control
measures, including revegetation of bare areas, are advised; and very severe indicates that significant erosion is
expected, loss of soil productivity and off-site damage are likely, and erosion-control measures are costly and
generally impractical. Ratings in the column hazard of erosion on roads and trails are based on the soil erodibility
factor K, slope, and content of rock fragments. The ratings apply to unsurfaced roads and trails. The hazard is
described as slight, moderate, or severe. A rating of slight indicates that little or no erosion is likely; moderate
indicates that some erosion is likely, that the roads or trails may require occasional maintenance; and that simple
erosion-control measures are needed; and severe indicates that significant erosion is expected, that the roads or
trails require frequent maintenance, and that costly erosion-control measures are needed. Ratings in the column
suitability for roads (natural surface) are based on slope, rock fragments on the surface, plasticity index, content
of sand, the Unified classification, depth to a water table, ponding, flooding, and the hazard of soil slippage. The
ratings indicate the suitability for using the natural surface of the soil for roads. The soils are described as well
suited, moderately suited, or poorly suited to this use.

Roads and Streets, Shallow Excavations, and Lawns and Landscaping
Soil properties influence the development of building sites, including the selection of the site, the design of the structure, construction, performance
after construction, and maintenance. This table shows the degree and kind of soil limitations that affect local roads and streets, shallow excavations,
and lawns and landscaping.
The ratings in the table are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features
that affect building site development. "Not limited" indicates that the soil has features that are very favorable for the specified use. Good performance
and very low maintenance can be expected. "Somewhat limited" indicates that the soil has features that are moderately favorable for the specified
use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be
expected. "Very limited" indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be
overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be
expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00.
They indicate gradations between the point at which a soil feature has the greatest negative impact on the use (1.00) and the point at which the soil
feature is not a limitation (0.00).
"Local roads and streets" have an all-weather surface and carry automobile and light truck traffic all year. They have a subgrade of cut or fill soil
material; a base of gravel, crushed rock, or soil material stabilized by lime or cement; and a surface of flexible material (asphalt), rigid material
(concrete), or gravel with a binder. The ratings are based on the soil properties that affect the ease of excavation and grading and the traffic-
supporting capacity. The properties that affect the ease of excavation and grading are depth to bedrock or a cemented pan, hardness of bedrock or a
cemented pan, depth to a water table, ponding, flooding, the amount of large stones, and slope. The properties that affect the traffic-supporting
capacity are soil strength (as inferred from the AASHTO group index number), subsidence, linear extensibility (shrink-swell potential), the potential for
frost action, depth to a water table, and ponding.
"Shallow excavations" are trenches or holes dug to a maximum depth of 5 or 6 feet for graves, utility lines, open ditches, or other purposes. The
ratings are based on the soil properties that influence the ease of digging and the resistance to sloughing. Depth to bedrock or a cemented pan,
hardness of bedrock or a cemented pan, the amount of large stones, and dense layers influence the ease of digging, filling, and compacting. Depth to
the seasonal high water table, flooding, and ponding may restrict the period when excavations can be made. Slope influences the ease of using
machinery. Soil texture, depth to the water table, and linear extensibility (shrink-swell potential) influence the resistance to sloughing.
"Lawns and landscaping" require soils on which turf and ornamental trees and shrubs can be established and maintained. Irrigation is not
considered in the ratings. The ratings are based on the soil properties that affect plant growth and trafficability after vegetation is established. The
properties that affect plant growth are reaction; depth to a water table; ponding; depth to bedrock or a cemented pan; the available water capacity in
the upper 40 inches; the content of salts, sodium, or calcium carbonate; and sulfidic materials. The properties that affect trafficability are flooding,
depth to a water table, ponding, slope, stoniness, and the amount of sand, clay, or organic matter in the surface layer.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design
and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil
between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a
specific soil.
The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel
experienced in the design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose specific design criteria were not considered in preparing the
information in this table. Local ordinances and regulations should be considered in planning, in site selection, and in design.

Kemmerer, WY 83101 STAR VALLEY CONSERVATION DISTRICT Board of Supervisors has reviewed the proposed Golden Dog, major subdivision east of Thayne, Wyoming and southwest of Star Valley Ranch,
Wyoming. This subdivision is part of a master plan that will eventually include 21 lots.
Due to a large variation of water levels in this section, SVCD recommends soil cuts to determine groundwater levels. If ground water is high, we recommend an enhanced septic system. We STRONGLY RECOMMEND that soil cuts be taken in the spring/early summer when
groundwater is highest. If soil cuts are done at other times know that static water level can fluctuate according to the amount of high-water runoff from year to year. A Water and Wastewater Study performed by Sunrise Engineering has been completed on this property. All recommendations regarding soil cuts and groundwater recommendations
supersede any recommendations found in this report.
The East Side Canal with water from the Salt River runs through the entirety of this subdivision. The lots on the west side of the East Side Canal include water rights. The lots on the west side of said canal have no water rights. The East Side Canal District must have
maintenance access to the canal. Any landscaping, shrubbery, etc., within one rod (16.5 feet)
of canal is strongly discouraged and is subject to removal by the canal district. For questions regarding this please contact our office at 307-885-7823. Please note the items in the Lincoln County Weed and Pest report that need to be addressed.
This report satisfies the Conservation District Review as required by Wyoming State Statute 18-5-306. No other use is intended or implied. If there is any more information we can provide for you, please let us know.
Yours truly,
STAR VALLEY CONSERVATION DISTRICT
Rollin Gardner Chairman
Subdivision Review Golden Dog Major Subdivision
Thayne, Wyoming November 29, 2022 Location The Golden Dog major subdivision is in the SE1/4 NW1/4 and the E1/2SW1/4 of Section 26 T35
R119W, west of Star Valley Ranch, Wyoming. The proposed subdivision is +/- 35 acres and will
be divided into 7 lots. This subdivision is part of a master plan that will eventually include 21 lots. Water Star Valley Conservation District (SVCD) personnel used the State Engineers Water Rights Data
Base to obtain groundwater information for this property. Well logs from wells in the vicinity
indicated the static water level is between 6 and 140 feet below ground surface. The East Side Canal with water from the Salt River runs through the entirety of this subdivision. The lots on the west side of the East Side Canal include water rights. The lots on
the west side of said canal have no water rights. The East Side Canal District must have maintenance access to the canal. Any landscaping, shrubbery, etc., within one rod (16.5 feet) of canal is strongly discouraged and is subject to removal by the canal district. For questions regarding this please contact our office at 307-885-7823. A Water and Wastewater Study performed by Sunrise Engineering has been completed on this property. All recommendations regarding soil cuts and groundwater recommendations supersede any recommendations found in this report.
Salt River
The Salt River is listed on Table C (Water Bodies with Water Quality Threats) of the Wyoming Department of Environmental Quality (WDEQ) 2020 Section 303(d) List. The Salt River does not support the designated use for contact recreation use due to elevated levels of fecal coliform bacteria.
In response to this listing, the Star Valley Conservation District (SVCD) initiated watershed-
planning activities for the Salt River Watershed in 2003. The Salt River Watershed Plan has been completed, was formally submitted to WDEQ and was accepted and signed by WDEQ in July 2005. SVCD completed a TMDL for the Salt River in 2016 which was submitted to WDEQ.
SVCD continues to monitor the watershed. We have collaborated with landowners to implement
fencing and off stream watering for livestock. We also provide a cost share to homeowners to
pump septic systems after attending our septic workshops.
The Salt River Watershed Plan identifies rural subdivisions as adversely affecting water quality in the Salt River Watershed. Storm water run-off from this subdivision should be managed using best management practices to ensure that pollutants such as storm water runoff, animal wastes,
sediment, and fertilizers do not reach the irrigation ditches or other surface waters in the area.
National Pollutant Discharge Elimination System (NPDES)
The Wyoming Department of Environmental Quality (WYDEQ) requires all construction sites that disturb 1 acre or more to have a construction NPDES permit. The areas do not have to be contiguous. The permit requires construction site operators to implement appropriate erosion and sediment control best management practices, control waste such as discarded building materials,
concrete truck wash-out, chemicals, litter, and sanitary wastes.
Operators of construction activities must develop a Storm Water Pollution Prevention Plan (SWPPP) that describes the measures to be implemented at the construction site that will eliminate or minimize pollutants from the project from reaching surface waters.
The terms and conditions of the permit must be implemented until the land disturbed by construction activities has been ‘finally stabilized.’ Finally stabilized is defined as “all soil disturbing activities at the site have been completed, and a uniform perennial vegetative cover with a density of 70% of the native background vegetative cover for the area has been
established on all disturbed unpaved areas and areas not covered by permanent structures”.
If construction will disturb 5 or more acres a stormwater permit from WYDEQ is required. For more information regarding the NPDES requirements please contact Katy Sprouse by phone or
email at 307-777-7570 (katysprouse@wyo.gove)Anita Rehner, WYDEQ Program Coordinator at
307-777-5622 or (arehner@state.wy.us).
Soils The following soils information provided by the Natural Resources Conservation Service (NRCS)
Soil Survey of Star Valley Area, Wyoming – Idaho. This information does not eliminate the need
for onsite investigation of the soils or for testing and analysis of these soils by a Wyoming Licensed Engineer experienced in the design and construction of engineering work. The proposed subdivision is comprised of 5 soil types identified as Greyback-Rooset Association,
hilly (GRD), Robana Silt loam 3 to 10 percent slopes (RoC), Robana Silt Loam 10 to 20 percent slopes
(RoD), Willow Creek-Bozeman association, undulating (WcC), Willow Creek-Bozeman association, hilly (WcD). You can see each of these areas clearly marked on the soils map, provided separately in this report.
Limitations: ‘not limited’ indicates that the soil has features that are favorable for the specified
use, good performance and very low maintenance can be expected. ‘Somewhat limited’ indicates that the soil has features that are moderately favorable for the specified use. The limitations can be overcome or minimized by special planning, design, and installation. Fair performance and moderate maintenance can be expected. Soils with ‘very limited’ designations
indicate that the soil has one or more features that are unfavorable for the specified use. The
limitations generally cannot be overcome without major soil reclamation, special design, or expensive installation procedures, poor performance and high maintenance can be expected. Dwelling with and without basements: The degree of limitations for dwellings with and
without basements in areas with GRD, is Very Limited due to slope and shrink-swell. For areas
containing RoC, the rating is Somewhat Limited due to shrink-swell. Areas containing RoD are rated as Very Limited due to slope and shrink-swell. Dwellings without basements in areas containing WcC are rated as Somewhat Limited due to shrink-swell. Dwellings with basements in these areas are rated as Not limited. Dwellings with and without basements in areas containing
WcD are rated as Very Limited due to slope and shrink-swell.
Soil cuts were not conducted as part of this review. Care should be taken not to locate buildings in
the intermittent drainage or any drainage channel where overland flooding could occur during early
spring snowmelt or heavy thunderstorms. Sewage Disposal: The degree of limitations for septic tank absorption fields in areas that contain GRD is Very Limited due to slope and slow water movement. Areas containing RoC are rated as
Somewhat Limited due to slow water movement. Areas containing RoD are rated as Very Limited
due to slope and slow water movement. Areas containing WcC are rated as Somewhat Limited due to slow water movement. Areas containing WcD are rated as Very Limited due to slope and slow water movement.
Roads and streets: The degree of limitations for roads and streets for areas containing GRD, and
RoC, RoD, and WcD are rated as Very Limited due to frost action, slope, low strength, and shrink-swell. Areas containing WcC are rated as Very Limited due to frost action, low strength, and shrink-swell.
Shallow excavations: The degree of limitations for shallow excavations in areas containing GRD,
RoD, and WcD are rated as Very Limited due to slope and cutbanks cave. Areas containing RoC and WcC are rated as Somewhat Limted due to cutbanks cave. Erosion Hazard: The potential of erosion hazard for unsurfaced roads and trails for areas
with GRD, RoD, and WcD are rated as Severe due to slope/erodibility. For areas containing RoC
and WcC the rating is Moderate due to slope/erodibility. The potential erosion hazard of construction sites is rated as Moderate for areas containing GRD, RoD, and WcD due to slope/erodibility. Areas containing RoC and WcC are rated as
Slight.
To avoid potential erosion or sedimentation problems all disturbed areas during subdivision construction, especially road banks, need to be mulched and seeded back to adapted grass/legumes and tress/shrubs as soon as possible. Topsoil should be stockpiled and saved
during construction, so adequate seedbeds can be prepared in the disturbed areas. Appropriate
erosion and sediment control best management practices should be installed and maintained for the duration of the project. Noxious Weeds
Lincoln County Weed and Pest report is included separately in this report. Please note the presence
of Black Henbane and Hounds Tongue. It is requested that the subdivision owners contact Lincoln County Weed and Pest to explain their weed control strategy. Lincoln County Weed & Pest furnishes herbicides for noxious weed control at a discount to
landowners. Check with Weed and Pest to see if you qualify. They also offer ATV sprayers and
25-gallon pickup sprayers for rent. All visits to the property as well as any consultations are at no charge. To contact Lincoln County Weed and Pest call 307-885-9333 (WEED).
Small Acreage Grazing/Livestock Management
Please be aware, grazing animals on small acreages can have a significant impact on the
condition of soil, water, plants, and other natural resources. Care should be taken to ensure agricultural activities such as grazing, corrals, pastures, feedlots, animal waste storage or spreading does not take place within any wellhead protection zone.
Best management practices should be implemented on these parcels to ensure animal wastes does not reach spring or Salt River during times of high water, snow melt, or storm run-off. This can be done by using berms, filters strips, grassed swales and catch ponds. The SVCD recommends the individual lot owners obtain a site-specific grazing and waste management conservation plan
from the local Natural Resources Conservation Service office in Afton. The plans are provided
free of charge. For more information, please contact Adam Clark, 307-886-9001 ext.109, adam.p.clark@usda.gov. Wildfire and Landscaping: Wildfire is possible in this area. Well planned landscaping can
reduce wildfire danger. The home should have a defensible space. SVCD recommends
following the guidelines in the University of Wyoming Barnyards and Backyards Living with Wildfire in Wyoming publication. http://www.uwyo.edu/barnbackyard/_files/documents/resources/wildfire2013/wildfire_web.pdf
Wildlife Friendly Fencing Fences cause the direct mortality of wildlife through entanglement and prohibition of movement to seasonal ranges. Fences constructed or currently in existence on the property should be designed to allow free and unrestricted movement of wildlife. Wyoming Game and Fish
Department recommends fences be built to minimally restrict livestock and horses, while allowing free movement of wildlife (e.g. a smooth bottom wire 16-18 inches above ground, a 39- inch maximum height and at least 12 inches between the top two wires). Wildlife can benefit from any area of open space. For more information please see Fencing Guidelines for Wildlife Wyoming Game & Fish Habitat Extension Bulletin No. 53 at the Wyoming Game and Fish

Homeowners should protect ornamental shrubs used for landscaping and future homeowners should know that, by state statute, the Wyoming Game and Fish Department is not liable for damage caused to ornamental plants by wildlife.
The potential exists for wildlife conflicts, especially between wildlife and free-ranging domestic pets. The landowner should take precautions to minimize harassment of wildlife by dogs and cats. It is illegal to allow pets to chase or kill wildlife. Likewise, rural landowners should recognize that black bears, mountain lions, and other carnivores may come near their dwellings and may pose a
threat to pets allowed to range freely. Sensitive Species and Historical Resources Sensitive, threatened, or endangered species were not evaluated as part of this review.

To Whom It May Concern,
An inspection of the proposed,Golden Dog Developments,LLC– Minor Subdivision -
within the SE1⁄4NW1⁄4 E1⁄2SW1⁄4 Section 26, T35N R119W,in Lincoln County,
Wyoming.The purpose of this inspection was to see if there are any of the noxious
weeds as to W.S. 11-5-102 (a) (xi). At the time of inspection,Black Henbane,
Hounds Tongue were present. These weeds are on the Wyoming State Noxious Weed
list as well as the Lincoln County Noxious Weed List.These plants have proven to be
very invasive and pernicious. According to Wyoming Statute it is illegal to allow any
state or county noxious weed to propagate freely. The subdivision representative will
need to contact Lincoln County Weed and Pest and explain their weed control strategy
or work with us to devise one.
Lincoln County Weed and Pest furnishes herbicides for noxious weed control at a
reduced cost share discount to the landowner.We also offer ATV sprayers and
25-gallon pickup sprayers for rent.
Please know that all visits to the above property as well as any consultations are at no
charge, so feel free to call or stop by the office any time if you have any questions.
Sincerely,
Bryan Nichols Travis Osmond

Dwellings and Small Commercial Buildings
Soil properties influence the development of building sites, including the selection of the site, the design of the structure, construction, performance
after construction, and maintenance. This table shows the degree and kind of soil limitations that affect dwellings and small commercial buildings.
The ratings in the table are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features
that affect building site development. "Not limited" indicates that the soil has features that are very favorable for the specified use. Good performance
and very low maintenance can be expected. "Somewhat limited" indicates that the soil has features that are moderately favorable for the specified
use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be
expected. "Very limited" indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be
overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be
expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00.
They indicate gradations between the point at which a soil feature has the greatest negative impact on the use (1.00) and the point at which the soil
feature is not a limitation (0.00).
"Dwellings" are single-family houses of three stories or less. For dwellings without basements, the foundation is assumed to consist of spread
footings of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth of maximum frost penetration, whichever is deeper. For
dwellings with basements, the foundation is assumed to consist of spread footings of reinforced concrete built on undisturbed soil at a depth of about
7 feet. The ratings for dwellings are based on the soil properties that affect the capacity of the soil to support a load without movement and on the
properties that affect excavation and construction costs. The properties that affect the load-supporting capacity include depth to a water table,
ponding, flooding, subsidence, linear extensibility (shrink-swell potential), and compressibility. Compressibility is inferred from the Unified
classification. The properties that affect the ease and amount of excavation include depth to a water table, ponding, flooding, slope, depth to bedrock
or a cemented pan, hardness of bedrock or a cemented pan, and the amount and size of rock fragments.
"Small commercial buildings" are structures that are less than three stories high and do not have basements. The foundation is assumed to consist
of spread footings of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth of maximum frost penetration, whichever is
deeper. The ratings are based on the soil properties that affect the capacity of the soil to support a load without movement and on the properties that
affect excavation and construction costs. The properties that affect the load-supporting capacity include depth to a water table, ponding, flooding,
subsidence, linear extensibility (shrink-swell potential), and compressibility (which is inferred from the Unified classification). The properties that affect
the ease and amount of excavation include flooding, depth to a water table, ponding, slope, depth to bedrock or a cemented pan, hardness of bedrock
or a cemented pan, and the amount and size of rock fragments.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design
and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil
between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a
specific soil.
The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel
experienced in the design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose specific design criteria were not considered in preparing the
information in this table. Local ordinances and regulations should be considered in planning, in site selection, and in design.

This table shows the degree and kind of soil limitations that affect septic tank absorption fields and sewage
lagoons. The ratings are both verbal and numerical. Rating class terms indicate the extent to which the soils are
limited by all of the soil features that affect these uses. "Not limited" indicates that the soil has features that are
very favorable for the specified use. Good performance and very low maintenance can be expected. "Somewhat
limited" indicates that the soil has features that are moderately favorable for the specified use. The limitations can
be overcome or minimized by special planning, design, or installation. Fair performance and moderate
maintenance can be expected. "Very limited" indicates that the soil has one or more features that are unfavorable
for the specified use. The limitations generally cannot be overcome without major soil reclamation, special design,
or expensive installation procedures. Poor performance and high maintenance can be expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal
fractions ranging from 0.01 to 1.00. They indicate gradations between the point at which a soil feature has the
greatest negative impact on the use (1.00) and the point at which the soil feature is not a limitation (0.00).
"Septic tank absorption fields" are areas in which effluent from a septic tank is distributed into the soil through
subsurface tiles or perforated pipe. Only that part of the soil between depths of 24 and 60 inches is evaluated.
The ratings are based on the soil properties that affect absorption of the effluent, construction and maintenance of
the system, and public health. Saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to
bedrock or a cemented pan, and flooding affect absorption of the effluent. Stones and boulders, ice, and bedrock
or a cemented pan interfere with installation. Subsidence interferes with installation and maintenance. Excessive
slope may cause lateral seepage and surfacing of the effluent in downslope areas.
Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below
the distribution lines. In these soils the absorption field may not adequately filter the effluent, particularly when the
system is new. As a result, the ground water may become contaminated.
"Sewage lagoons" are shallow ponds constructed to hold sewage while aerobic bacteria decompose the solid
and liquid wastes. Lagoons should have a nearly level floor surrounded by cut slopes or embankments of
compacted soil. Nearly impervious soil material for the lagoon floor and sides is required to minimize seepage and
contamination of ground water. Considered in the ratings are slope, Ksat, depth to a water table, ponding, depth
to bedrock or a cemented pan, flooding, large stones, and content of organic matter.
Ksat is a critical property affecting the suitability for sewage lagoons. Most porous soils eventually become
sealed when they are used as sites for sewage lagoons. Until sealing occurs, however, the hazard of pollution is
severe. Soils that have a Ksat rate of more than 14 micrometers per second are too porous for the proper
functioning of sewage lagoons. In these soils, seepage of the effluent can result in contamination of the ground
water. Ground-water contamination is also a hazard if fractured bedrock is within a depth of 40 inches, if the water
table is high enough to raise the level of sewage in the lagoon, or if floodwater overtops the lagoon.
A high content of organic matter is detrimental to proper functioning of the lagoon because it inhibits aerobic
activity. Slope, bedrock, and cemented pans can cause construction problems, and large stones can hinder
compaction of the lagoon floor. If the lagoon is to be uniformly deep throughout, the slope must be gentle enough
and the soil material must be thick enough over bedrock or a cemented pan to make land smoothing practical.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning
site investigations prior to design and construction. The information, however, has limitations. For example,
estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7
feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a
specific soil.
The information is not site specific and does not eliminate the need for onsite investigation of the soils or for
testing and analysis by personnel experienced in the design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose specific design criteria were
not considered in preparing the information in this table. Local ordinances and regulations should be considered in
planning, in site selection, and in design.

Roads and Streets, Shallow Excavations, and Lawns and Landscaping
Soil properties influence the development of building sites, including the selection of the site, the design of the structure, construction, performance
after construction, and maintenance. This table shows the degree and kind of soil limitations that affect local roads and streets, shallow excavations,
and lawns and landscaping.
The ratings in the table are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features
that affect building site development. "Not limited" indicates that the soil has features that are very favorable for the specified use. Good performance
and very low maintenance can be expected. "Somewhat limited" indicates that the soil has features that are moderately favorable for the specified
use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be
expected. "Very limited" indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be
overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be
expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00.
They indicate gradations between the point at which a soil feature has the greatest negative impact on the use (1.00) and the point at which the soil
feature is not a limitation (0.00).
"Local roads and streets" have an all-weather surface and carry automobile and light truck traffic all year. They have a subgrade of cut or fill soil
material; a base of gravel, crushed rock, or soil material stabilized by lime or cement; and a surface of flexible material (asphalt), rigid material
(concrete), or gravel with a binder. The ratings are based on the soil properties that affect the ease of excavation and grading and the traffic-
supporting capacity. The properties that affect the ease of excavation and grading are depth to bedrock or a cemented pan, hardness of bedrock or a
cemented pan, depth to a water table, ponding, flooding, the amount of large stones, and slope. The properties that affect the traffic-supporting
capacity are soil strength (as inferred from the AASHTO group index number), subsidence, linear extensibility (shrink-swell potential), the potential for
frost action, depth to a water table, and ponding.
"Shallow excavations" are trenches or holes dug to a maximum depth of 5 or 6 feet for graves, utility lines, open ditches, or other purposes. The
ratings are based on the soil properties that influence the ease of digging and the resistance to sloughing. Depth to bedrock or a cemented pan,
hardness of bedrock or a cemented pan, the amount of large stones, and dense layers influence the ease of digging, filling, and compacting. Depth to
the seasonal high water table, flooding, and ponding may restrict the period when excavations can be made. Slope influences the ease of using
machinery. Soil texture, depth to the water table, and linear extensibility (shrink-swell potential) influence the resistance to sloughing.
"Lawns and landscaping" require soils on which turf and ornamental trees and shrubs can be established and maintained. Irrigation is not
considered in the ratings. The ratings are based on the soil properties that affect plant growth and trafficability after vegetation is established. The
properties that affect plant growth are reaction; depth to a water table; ponding; depth to bedrock or a cemented pan; the available water capacity in
the upper 40 inches; the content of salts, sodium, or calcium carbonate; and sulfidic materials. The properties that affect trafficability are flooding,
depth to a water table, ponding, slope, stoniness, and the amount of sand, clay, or organic matter in the surface layer.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design
and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil
between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a

Erosion Hazard of Natural Surface Roads and Construction Sites
This table can help land owners or land users plan the use of soils for unpaved roads. Interpretive ratings are
given for the soils according to the limitations that affect unpaved roads. The ratings are both verbal and
numerical. Some rating class terms indicate the degree to which the soils are suited to a specified practice. Well
suited indicates that the soil has features that are favorable for the specified practice and has no limitations. Good
performance can be expected, and little or no maintenance is needed. Moderately suited indicates that the soil
has features that are moderately favorable for the specified practice. One or more soil properties are less than
desirable, and fair performance can be expected. Some maintenance is needed. Poorly suited indicates that the
soil has one or more properties that are unfavorable for the specified practice. Overcoming the unfavorable
properties requires special design, extra maintenance, and costly alteration. Unsuited indicates that the expected
performance of the soil is unacceptable for the specified practice or that extreme measures are needed to
overcome the undesirable soil properties. Numerical ratings in the table indicate the severity of individual
limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the specified practice (1.00) and the
point at which the soil feature is not a limitation (0.00). The paragraphs that follow indicate the soil properties
considered in rating the soils for forest management practices. More detailed information about the criteria used in
the ratings is available in the "National Forestry Manual," which is available in local offices of the Natural
Resources Conservation Service or on the Internet. Ratings in the column hazard of off-road or off-trail erosion
are based on slope and on soil erodibility factor K. The soil loss is caused by sheet or rill erosion in off-road or off-
trail areas where 50 to 75 percent of the surface has been exposed by logging, grazing, mining, or other kinds of
disturbance. The hazard is described as slight, moderate, severe, or very severe. A rating of slight indicates that
erosion is unlikely under ordinary climatic conditions; moderate indicates that some erosion is likely and that
erosion-control measures may be needed; severe indicates that erosion is very likely and that erosion-control
measures, including revegetation of bare areas, are advised; and very severe indicates that significant erosion is
expected, loss of soil productivity and off-site damage are likely, and erosion-control measures are costly and
generally impractical. Ratings in the column hazard of erosion on roads and trails are based on the soil erodibility
factor K, slope, and content of rock fragments. The ratings apply to unsurfaced roads and trails. The hazard is
described as slight, moderate, or severe. A rating of slight indicates that little or no erosion is likely; moderate
indicates that some erosion is likely, that the roads or trails may require occasional maintenance; and that simple
erosion-control measures are needed; and severe indicates that significant erosion is expected, that the roads or
trails require frequent maintenance, and that costly erosion-control measures are needed. Ratings in the column
suitability for roads (natural surface) are based on slope, rock fragments on the surface, plasticity index, content
of sand, the Unified classification, depth to a water table, ponding, flooding, and the hazard of soil slippage. The
ratings indicate the suitability for using the natural surface of the soil for roads. The soils are described as well
suited, moderately suited, or poorly suited to this use.

Kemmerer, WY 83101 STAR VALLEY CONSERVATION DISTRICT Board of Supervisors has reviewed the proposed Neal Wieblehaus, major subdivision east of Thayne, Wyoming and southwest of Star Valley
Ranch, Wyoming. This subdivision is part of a master plan that will eventually include 21 lots.
Due to a large variation of water levels in this section, SVCD recommends soil cuts to determine groundwater levels. If ground water is high, we recommend an enhanced septic system. We STRONGLY RECOMMEND that soil cuts be taken in the spring/early summer when groundwater
is highest. If soil cuts are done at other times know that static water level can fluctuate according
to the amount of high-water runoff from year to year. A Water and Wastewater Study performed by Sunrise Engineering has been completed on this property. All recommendations regarding soil cuts and groundwater recommendations
supersede any recommendations found in this report.
The East Side Canal with water from the Salt River runs through the entirety of this subdivision. The lots on the west side of the East Side Canal include water rights. The lots on the west side of said canal have no water rights. The East Side Canal District must have
maintenance access to the canal. Any landscaping, shrubbery, etc., within one rod (16.5 feet)
of canal is strongly discouraged and is subject to removal by the canal district. For questions regarding this please contact our office at 307-885-7823. Please note the items in the Lincoln County Weed and Pest report that need to be addressed.
This report satisfies the Conservation District Review as required by Wyoming State Statute 18-5-306. No other use is intended or implied. If there is any more information we can provide for you, please let us know.
Yours truly,

STRONGLY RECOMMEND that soil cuts be taken in the spring/early summer when groundwater is highest. If soil cuts are done at other times know that static water level can fluctuate according to the amount of high-water runoff from year to year.
The East Side Canal with water from the Salt River runs through the entirety of this
subdivision. The lots on the west side of the East Side Canal include water rights. The lots on the west side of said canal have no water rights. The East Side Canal District must have maintenance access to the canal. Any landscaping, shrubbery, etc., within one rod (16.5 feet) of canal is strongly discouraged and is subject to removal by the canal district. For questions
regarding this please contact our office at 307-885-7823.
Salt River The Salt River is listed on Table C (Water Bodies with Water Quality Threats) of the Wyoming Department of Environmental Quality (WDEQ) 2020 Section 303(d) List. The Salt River does
not support the designated use for contact recreation use due to elevated levels of fecal coliform
bacteria.
In response to this listing, the Star Valley Conservation District (SVCD) initiated watershed-planning activities for the Salt River Watershed in 2003. The Salt River Watershed Plan has been completed, was formally submitted to WDEQ and was accepted and signed by WDEQ in July
2005. SVCD completed a TMDL for the Salt River in 2016 which was submitted to WDEQ.
SVCD continues to monitor the watershed. We have collaborated with landowners to implement fencing and off stream watering for livestock. We also provide a cost share to homeowners to
pump septic systems after attending our septic workshops.
The Salt River Watershed Plan identifies rural subdivisions as adversely affecting water quality in the Salt River Watershed. Storm water run-off from this subdivision should be managed using best management practices to ensure that pollutants such as storm water runoff, animal wastes, sediment, and fertilizers do not reach the irrigation ditches or other surface waters in the area.
National Pollutant Discharge Elimination System (NPDES) The Wyoming Department of Environmental Quality (WYDEQ) requires all construction sites that disturb 1 acre or more to have a construction NPDES permit. The areas do not have to be contiguous. The permit requires construction site operators to implement appropriate erosion and
sediment control best management practices, control waste such as discarded building materials,
concrete truck wash-out, chemicals, litter, and sanitary wastes. Operators of construction activities must develop a Storm Water Pollution Prevention Plan (SWPPP) that describes the measures to be implemented at the construction site that will
eliminate or minimize pollutants from the project from reaching surface waters.
The terms and conditions of the permit must be implemented until the land disturbed by construction activities has been ‘finally stabilized.’ Finally stabilized is defined as “all soil disturbing activities at the site have been completed, and a uniform perennial vegetative cover
with a density of 70% of the native background vegetative cover for the area has been
established on all disturbed unpaved areas and areas not covered by permanent structures”. If construction will disturb 5 or more acres a stormwater permit from WYDEQ is required.
For more information regarding the NPDES requirements please contact Katy Sprouse by phone or
email at 307-777-7570 (katysprouse@wyo.gove)Anita Rehner, WYDEQ Program Coordinator at 307-777-5622 or (arehner@state.wy.us).
Soils
The following soils information provided by the Natural Resources Conservation Service (NRCS)
Soil Survey of Star Valley Area, Wyoming – Idaho. This information does not eliminate the need for onsite investigation of the soils or for testing and analysis of these soils by a Wyoming Licensed Engineer experienced in the design and construction of engineering work.
The proposed subdivision is comprised of 5 soil types identified as Greyback-Rooset Association,
hilly (GRD), Robana Silt loam 3 to 10 percent slopes (RoC), Robana Silt Loam 10 to 20 percent slopes (RoD), Willow Creek-Bozeman association, undulating (WcC), Willow Creek-Bozeman association, hilly (WcD). You can see each of these areas clearly marked on the soils map, provided separately in this report.
Limitations: ‘not limited’ indicates that the soil has features that are favorable for the specified use, good performance and very low maintenance can be expected. ‘Somewhat limited’ indicates that the soil has features that are moderately favorable for the specified use. The limitations can be overcome or minimized by special planning, design, and installation. Fair
performance and moderate maintenance can be expected. Soils with ‘very limited’ designations
indicate that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be overcome without major soil reclamation, special design, or expensive installation procedures, poor performance and high maintenance can be expected.
Dwelling with and without basements: The degree of limitations for dwellings with and without basements in areas with GRD, is Very Limited due to slope and shrink-swell. For areas
containing RoC, the rating is Somewhat Limited due to shrink-swell. Areas containing RoD are
rated as Very Limited due to slope and shrink-swell. Dwellings without basements in areas containing WcC are rated as Somewhat Limited due to shrink-swell. Dwellings with basements in these areas are rated as Not limited. Dwellings with and without basements in areas containing WcD are rated as Very Limited due to slope and shrink-swell.
Soil cuts were not conducted as part of this review. Care should be taken not to locate buildings in the intermittent drainage or any drainage channel where overland flooding could occur during early
spring snowmelt or heavy thunderstorms. Sewage Disposal: The degree of limitations for septic tank absorption fields in areas that contain GRD is Very Limited due to slope and slow water movement. Areas containing RoC are rated as Somewhat Limited due to slow water movement. Areas containing RoD are rated as Very Limited
due to slope and slow water movement. Areas containing WcC are rated as Somewhat Limited due to slow water movement. Areas containing WcD are rated as Very Limited due to slope and slow water movement. Roads and streets: The degree of limitations for roads and streets for areas containing GRD, and
RoC, RoD, and WcD are rated as Very Limited due to frost action, slope, low strength, and shrink-swell. Areas containing WcC are rated as Very Limited due to frost action, low strength, and shrink-swell. Shallow excavations: The degree of limitations for shallow excavations in areas containing GRD,
RoD, and WcD are rated as Very Limited due to slope and cutbanks cave. Areas containing RoC and WcC are rated as Somewhat Limted due to cutbanks cave. Erosion Hazard: The potential of erosion hazard for unsurfaced roads and trails for areas with GRD, RoD, and WcD are rated as Severe due to slope/erodibility. For areas containing RoC
and WcC the rating is Moderate due to slope/erodibility. The potential erosion hazard of construction sites is rated as Moderate for areas containing GRD, RoD, and WcD due to slope/erodibility. Areas containing RoC and WcC are rated as Slight.
To avoid potential erosion or sedimentation problems all disturbed areas during subdivision construction, especially road banks, need to be mulched and seeded back to adapted grass/legumes and tress/shrubs as soon as possible. Topsoil should be stockpiled and saved during construction, so adequate seedbeds can be prepared in the disturbed areas. Appropriate
erosion and sediment control best management practices should be installed and maintained for the duration of the project. Noxious Weeds Lincoln County Weed and Pest report is included separately in this report. Please note the presence
of Black Henbane and Hounds Tongue. It is requested that the subdivision owners contact Lincoln County Weed and Pest to explain their weed control strategy. Lincoln County Weed & Pest furnishes herbicides for noxious weed control at a discount to
landowners. Check with Weed and Pest to see if you qualify. They also offer ATV sprayers and
25-gallon pickup sprayers for rent. All visits to the property as well as any consultations are at no charge. To contact Lincoln
County Weed and Pest call 307-885-9333 (WEED).
Small Acreage Grazing/Livestock Management Please be aware, grazing animals on small acreages can have a significant impact on the condition of soil, water, plants, and other natural resources.
Care should be taken to ensure agricultural activities such as grazing, corrals, pastures, feedlots,
animal waste storage or spreading does not take place within any wellhead protection zone. Best management practices should be implemented on these parcels to ensure animal wastes does not reach spring or Salt River during times of high water, snow melt, or storm run-off. This can be
done by using berms, filters strips, grassed swales and catch ponds. The SVCD recommends the
individual lot owners obtain a site-specific grazing and waste management conservation plan from the local Natural Resources Conservation Service office in Afton. The plans are provided free of charge. For more information, please contact Adam Clark, 307-886-9001 ext.109, adam.p.clark@usda.gov.
Wildfire and Landscaping: Wildfire is possible in this area. Well planned landscaping can reduce wildfire danger. The home should have a defensible space. SVCD recommends
following the guidelines in the University of Wyoming Barnyards and Backyards Living with
Wildfire in Wyoming publication. http://www.uwyo.edu/barnbackyard/_files/documents/resources/wildfire2013/wildfire_web.pdf
Wildlife Friendly Fencing Fences cause the direct mortality of wildlife through entanglement and prohibition of movement
to seasonal ranges. Fences constructed or currently in existence on the property should be designed to allow free and unrestricted movement of wildlife. Wyoming Game and Fish Department recommends fences be built to minimally restrict livestock and horses, while allowing free movement of wildlife (e.g. a smooth bottom wire 16-18 inches above ground, a 39- inch maximum height and at least 12 inches between the top two wires). Wildlife can benefit from
any area of open space. For more information please see Fencing Guidelines for Wildlife Wyoming Game & Fish Habitat Extension Bulletin No. 53 at the Wyoming Game and Fish website http://gf.state.wy.us/downloads/pdf/habitat/Bulletin%20No.%2053.pdf.
Homeowners should protect ornamental shrubs used for landscaping and future homeowners
should know that, by state statute, the Wyoming Game and Fish Department is not liable for damage caused to ornamental plants by wildlife. The potential exists for wildlife conflicts, especially between wildlife and free-ranging domestic pets. The landowner should take precautions to minimize harassment of wildlife by dogs and cats.
It is illegal to allow pets to chase or kill wildlife. Likewise, rural landowners should recognize that black bears, mountain lions, and other carnivores may come near their dwellings and may pose a threat to pets allowed to range freely. Sensitive Species and Historical Resources
Sensitive, threatened, or endangered species were not evaluated as part of this review.

To Whom It May Concern,
An inspection of the proposed,Neal Wiebelhaus and Molly Wiebelhaus – Major
Subdivision - within the SW¼NE¼ and the SE¼NW¼ of Section 26, T35N R119W,
Lincoln County, Wyoming.The purpose of this inspection was to see if there are any
of the noxious weeds as to W.S. 11-5-102 (a) (xi).At the time of inspection,Black
Henbane, Hounds Tongue were present. These weeds are on the Wyoming State
Noxious Weed list as well as the Lincoln County Noxious Weed List.These plants
have proven to be very invasive and pernicious. According to Wyoming Statute it is
illegal to allow any state or county noxious weed to propagate freely. The subdivision
representative will need to contact Lincoln County Weed and Pest and explain their
weed control strategy or work with us to devise one.
Lincoln County Weed and Pest furnishes herbicides for noxious weed control at a
reduced cost share discount to the landowner.We also offer ATV sprayers and
25-gallon pickup sprayers for rent.
Please know that all visits to the above property as well as any consultations are at no
charge, so feel free to call or stop by the office any time if you have any questions.
Sincerely,

Dwellings and Small Commercial Buildings
Soil properties influence the development of building sites, including the selection of the site, the design of the structure, construction, performance
after construction, and maintenance. This table shows the degree and kind of soil limitations that affect dwellings and small commercial buildings.
The ratings in the table are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features
that affect building site development. "Not limited" indicates that the soil has features that are very favorable for the specified use. Good performance
and very low maintenance can be expected. "Somewhat limited" indicates that the soil has features that are moderately favorable for the specified
use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be
expected. "Very limited" indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be
overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be
expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00.
They indicate gradations between the point at which a soil feature has the greatest negative impact on the use (1.00) and the point at which the soil
feature is not a limitation (0.00).
"Dwellings" are single-family houses of three stories or less. For dwellings without basements, the foundation is assumed to consist of spread
footings of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth of maximum frost penetration, whichever is deeper. For
dwellings with basements, the foundation is assumed to consist of spread footings of reinforced concrete built on undisturbed soil at a depth of about
7 feet. The ratings for dwellings are based on the soil properties that affect the capacity of the soil to support a load without movement and on the
properties that affect excavation and construction costs. The properties that affect the load-supporting capacity include depth to a water table,
ponding, flooding, subsidence, linear extensibility (shrink-swell potential), and compressibility. Compressibility is inferred from the Unified
classification. The properties that affect the ease and amount of excavation include depth to a water table, ponding, flooding, slope, depth to bedrock
or a cemented pan, hardness of bedrock or a cemented pan, and the amount and size of rock fragments.
"Small commercial buildings" are structures that are less than three stories high and do not have basements. The foundation is assumed to consist
of spread footings of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth of maximum frost penetration, whichever is
deeper. The ratings are based on the soil properties that affect the capacity of the soil to support a load without movement and on the properties that
affect excavation and construction costs. The properties that affect the load-supporting capacity include depth to a water table, ponding, flooding,
subsidence, linear extensibility (shrink-swell potential), and compressibility (which is inferred from the Unified classification). The properties that affect
the ease and amount of excavation include flooding, depth to a water table, ponding, slope, depth to bedrock or a cemented pan, hardness of bedrock
or a cemented pan, and the amount and size of rock fragments.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design
and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil
between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a
specific soil.
The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel
experienced in the design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose specific design criteria were not considered in preparing the
information in this table. Local ordinances and regulations should be considered in planning, in site selection, and in design.

Sewage Disposal
This table shows the degree and kind of soil limitations that affect septic tank absorption fields and sewage
lagoons. The ratings are both verbal and numerical. Rating class terms indicate the extent to which the soils are
limited by all of the soil features that affect these uses. "Not limited" indicates that the soil has features that are
very favorable for the specified use. Good performance and very low maintenance can be expected. "Somewhat
limited" indicates that the soil has features that are moderately favorable for the specified use. The limitations can
be overcome or minimized by special planning, design, or installation. Fair performance and moderate
maintenance can be expected. "Very limited" indicates that the soil has one or more features that are unfavorable
for the specified use. The limitations generally cannot be overcome without major soil reclamation, special design,
or expensive installation procedures. Poor performance and high maintenance can be expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal
fractions ranging from 0.01 to 1.00. They indicate gradations between the point at which a soil feature has the
greatest negative impact on the use (1.00) and the point at which the soil feature is not a limitation (0.00).
"Septic tank absorption fields" are areas in which effluent from a septic tank is distributed into the soil through
subsurface tiles or perforated pipe. Only that part of the soil between depths of 24 and 60 inches is evaluated.
The ratings are based on the soil properties that affect absorption of the effluent, construction and maintenance of
the system, and public health. Saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to
bedrock or a cemented pan, and flooding affect absorption of the effluent. Stones and boulders, ice, and bedrock
or a cemented pan interfere with installation. Subsidence interferes with installation and maintenance. Excessive
slope may cause lateral seepage and surfacing of the effluent in downslope areas.
Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below
the distribution lines. In these soils the absorption field may not adequately filter the effluent, particularly when the
system is new. As a result, the ground water may become contaminated.
"Sewage lagoons" are shallow ponds constructed to hold sewage while aerobic bacteria decompose the solid
and liquid wastes. Lagoons should have a nearly level floor surrounded by cut slopes or embankments of
compacted soil. Nearly impervious soil material for the lagoon floor and sides is required to minimize seepage and
contamination of ground water. Considered in the ratings are slope, Ksat, depth to a water table, ponding, depth
to bedrock or a cemented pan, flooding, large stones, and content of organic matter.
Ksat is a critical property affecting the suitability for sewage lagoons. Most porous soils eventually become
sealed when they are used as sites for sewage lagoons. Until sealing occurs, however, the hazard of pollution is
severe. Soils that have a Ksat rate of more than 14 micrometers per second are too porous for the proper
functioning of sewage lagoons. In these soils, seepage of the effluent can result in contamination of the ground
water. Ground-water contamination is also a hazard if fractured bedrock is within a depth of 40 inches, if the water
table is high enough to raise the level of sewage in the lagoon, or if floodwater overtops the lagoon.
A high content of organic matter is detrimental to proper functioning of the lagoon because it inhibits aerobic
activity. Slope, bedrock, and cemented pans can cause construction problems, and large stones can hinder
compaction of the lagoon floor. If the lagoon is to be uniformly deep throughout, the slope must be gentle enough
and the soil material must be thick enough over bedrock or a cemented pan to make land smoothing practical.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning
site investigations prior to design and construction. The information, however, has limitations. For example,
estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7
feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a

Roads and Streets, Shallow Excavations, and Lawns and Landscaping
Soil properties influence the development of building sites, including the selection of the site, the design of the structure, construction, performance
after construction, and maintenance. This table shows the degree and kind of soil limitations that affect local roads and streets, shallow excavations,
and lawns and landscaping.
The ratings in the table are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features
that affect building site development. "Not limited" indicates that the soil has features that are very favorable for the specified use. Good performance
and very low maintenance can be expected. "Somewhat limited" indicates that the soil has features that are moderately favorable for the specified
use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be
expected. "Very limited" indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be
overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be
expected.
Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00.
They indicate gradations between the point at which a soil feature has the greatest negative impact on the use (1.00) and the point at which the soil
feature is not a limitation (0.00).
"Local roads and streets" have an all-weather surface and carry automobile and light truck traffic all year. They have a subgrade of cut or fill soil
material; a base of gravel, crushed rock, or soil material stabilized by lime or cement; and a surface of flexible material (asphalt), rigid material
(concrete), or gravel with a binder. The ratings are based on the soil properties that affect the ease of excavation and grading and the traffic-
supporting capacity. The properties that affect the ease of excavation and grading are depth to bedrock or a cemented pan, hardness of bedrock or a
cemented pan, depth to a water table, ponding, flooding, the amount of large stones, and slope. The properties that affect the traffic-supporting
capacity are soil strength (as inferred from the AASHTO group index number), subsidence, linear extensibility (shrink-swell potential), the potential for
frost action, depth to a water table, and ponding.
"Shallow excavations" are trenches or holes dug to a maximum depth of 5 or 6 feet for graves, utility lines, open ditches, or other purposes. The
ratings are based on the soil properties that influence the ease of digging and the resistance to sloughing. Depth to bedrock or a cemented pan,
hardness of bedrock or a cemented pan, the amount of large stones, and dense layers influence the ease of digging, filling, and compacting. Depth to
the seasonal high water table, flooding, and ponding may restrict the period when excavations can be made. Slope influences the ease of using
machinery. Soil texture, depth to the water table, and linear extensibility (shrink-swell potential) influence the resistance to sloughing.
"Lawns and landscaping" require soils on which turf and ornamental trees and shrubs can be established and maintained. Irrigation is not
considered in the ratings. The ratings are based on the soil properties that affect plant growth and trafficability after vegetation is established. The
properties that affect plant growth are reaction; depth to a water table; ponding; depth to bedrock or a cemented pan; the available water capacity in
the upper 40 inches; the content of salts, sodium, or calcium carbonate; and sulfidic materials. The properties that affect trafficability are flooding,
depth to a water table, ponding, slope, stoniness, and the amount of sand, clay, or organic matter in the surface layer.
Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design
and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil
between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a
specific soil.
The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel
experienced in the design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose specific design criteria were not considered in preparing the
information in this table. Local ordinances and regulations should be considered in planning, in site selection, and in design.

Erosion Hazard of Natural Surface Roads and Construction Sites
This table can help land owners or land users plan the use of soils for unpaved roads. Interpretive ratings are
given for the soils according to the limitations that affect unpaved roads. The ratings are both verbal and
numerical. Some rating class terms indicate the degree to which the soils are suited to a specified practice. Well
suited indicates that the soil has features that are favorable for the specified practice and has no limitations. Good
performance can be expected, and little or no maintenance is needed. Moderately suited indicates that the soil
has features that are moderately favorable for the specified practice. One or more soil properties are less than
desirable, and fair performance can be expected. Some maintenance is needed. Poorly suited indicates that the
soil has one or more properties that are unfavorable for the specified practice. Overcoming the unfavorable
properties requires special design, extra maintenance, and costly alteration. Unsuited indicates that the expected
performance of the soil is unacceptable for the specified practice or that extreme measures are needed to
overcome the undesirable soil properties. Numerical ratings in the table indicate the severity of individual
limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the specified practice (1.00) and the
point at which the soil feature is not a limitation (0.00). The paragraphs that follow indicate the soil properties
considered in rating the soils for forest management practices. More detailed information about the criteria used in
the ratings is available in the "National Forestry Manual," which is available in local offices of the Natural
Resources Conservation Service or on the Internet. Ratings in the column hazard of off-road or off-trail erosion
are based on slope and on soil erodibility factor K. The soil loss is caused by sheet or rill erosion in off-road or off-
trail areas where 50 to 75 percent of the surface has been exposed by logging, grazing, mining, or other kinds of
disturbance. The hazard is described as slight, moderate, severe, or very severe. A rating of slight indicates that
erosion is unlikely under ordinary climatic conditions; moderate indicates that some erosion is likely and that
erosion-control measures may be needed; severe indicates that erosion is very likely and that erosion-control
measures, including revegetation of bare areas, are advised; and very severe indicates that significant erosion is
expected, loss of soil productivity and off-site damage are likely, and erosion-control measures are costly and
generally impractical. Ratings in the column hazard of erosion on roads and trails are based on the soil erodibility
factor K, slope, and content of rock fragments. The ratings apply to unsurfaced roads and trails. The hazard is
described as slight, moderate, or severe. A rating of slight indicates that little or no erosion is likely; moderate
indicates that some erosion is likely, that the roads or trails may require occasional maintenance; and that simple
erosion-control measures are needed; and severe indicates that significant erosion is expected, that the roads or
trails require frequent maintenance, and that costly erosion-control measures are needed. Ratings in the column
suitability for roads (natural surface) are based on slope, rock fragments on the surface, plasticity index, content
of sand, the Unified classification, depth to a water table, ponding, flooding, and the hazard of soil slippage. The
ratings indicate the suitability for using the natural surface of the soil for roads. The soils are described as well
suited, moderately suited, or poorly suited to this use.

RE:Alpenglow Hills Subdivision WDEQ 2023-79
Dear Commissioners:
The State Engineer’s Office Ground Water Division received application material related to the Aspen
Valley Springs Subdivision from the Wyoming Department of Environmental Quality,requesting
information and advice to the Water Quality Division.
The proposed subdivision is to be located in SESW,NESW,and in parts of SENW,SWNE,NWSE of
section 26,T35N,R119W,Lincoln County,Wyoming.The subdivision consists of 21 lots.Water supply
is proposed to be provided by on lot wells.Based upon the review of both the subdivision application and
a preliminary search of the agency’s water rights database,the State Engineer’s Office offers the
following:
Our office reviewed the referenced submittal in compliance with W.S.18-5-306.We find that in respect to
W.S.18-5-306(a)(xi)the subdivider needs to address the following items:
1.Our records indicate that there may be some irrigated acres associated with the subdivision lands
under Permit P1266.0E .These acres need to be addressed per Statute.See item 7 for a summary
of our findings and the processes to address these acres per Statute.
2.Our records indicate the following well permits should be addressed:Permit P75214.0W.Our office
recommends that the subdivider provide GPS coordinates for the wells and the legal location
description including subdivision name and lot number,as well as the legal location description
including subdivision name and lot number of where the domestic and stock uses are occurring.This
action can be filed via official request to our office to update records along with a warranty deed
showing current ownership of the property.
Additional Comments:
3.An approved permit from the Wyoming State Engineer’s Office is required prior to the drilling of any
water well.The procurement of the necessary and appropriate State Engineer water right permit
allows the applicant to attempt to develop a water supply adequate to meet the proposed needs,and is
no guarantee that any water will be physically available.
Surface Water Ground Water Board of Control
(307)777-6475 (307)777-6163 (307)777-6178
4.If any new wells are proposed,they must be constructed in accordance with the State Engineer’s
Office Rules and Regulations,Part III,Water Well Minimum Construction Standards.
5.Any well not to be used must be properly plugged and abandoned as outlined in the above referenced
rules and regulations.
6.Any wells developed for uses that do NOT fall within the definition of domestic or stock use require
adjudication by the Board of Control.
7.The water right search revealed other existing water rights attached to the subdivision lands.Those
water rights must be addressed as outlined in Wyoming Statute 18-5-306(a)(xi).To date,the State
Engineer’s Office has not received any paperwork addressing the intended disposition of the water
rights.
Wyoming Statute 18-5-306(a)(xi):
(xi)With respect to any water rights appurtenant to lands to be subdivided in accordance with this chapter
and prior to final approval of the subdivision permit,the subdivider shall provide the following:
(A)The intended disposition of the water rights,by:
(I)Written documentation from the state engineer or the state board of control that the subdivider
submitted to the state engineer or the state board of control all documents necessary to
voluntarily abandon the water rights,cancel any unadjudicated permits or eliminate applicable
lands from any unadjudicated permits.The subdivider shall notify any purchasers of this
action;
(II)Written documentation from the state board of control that the subdivider has submitted to the
state board of control all documents necessary to change the use or place of use to provide for
beneficial use of the water rights outside the subdivision;
(III)A plan,accompanied by written documentation from the state engineer approving the plan,for
the distribution of the water rights appurtenant to the land to be subdivided.The plan shall
specify the distribution of the water to the lots within the subdivision and shall include written
documentation from the state board of control that the subdivider submitted to the state board
of control all documents necessary to change the use,place of use or point of diversion or
means of conveyance in accordance with W.S.41-3-103,41-3-104 or 41-3-114;or
(IV)Written documentation from the state board of control that it has accepted an authorization to
detach water rights appurtenant to the lands to be subdivided in accordance with rules and
regulations promulgated by the state board of control.
(B)If the subdivision is located within lands served by or crossed by a ditch,irrigation works or other
water conveyance system,evidence that the subdivider submitted the plan to the public entity,
company,association or appropriators responsible for the ditch,irrigation works or other water
conveyance system for review and recommendation at least sixty (60)days prior to the submittal of
the application for the subdivision permit to the board.Upon receipt of the plan,the public entity,
company,association or appropriators shall notify the subdivider if and how the subdivision will
create a significant additional burden or risk of liability;
(C)Evidence that the subdivider will specifically state on all offers and solicitations relative to the
subdivision the subdivider's intent to comply with this paragraph and that the subdivider does not
warrant to a purchaser that the purchaser shall have any rights to the natural flow of any stream
within or adjacent to the proposed subdivision.The subdivider shall further state that Wyoming law
does not recognize any riparian rights to the continued natural flow of a stream or river for persons
living on the banks of the stream or river;
(D)If the subdivision is located within the boundaries of an irrigation district that is subject to the
provisions of title 41,chapter 7 of the Wyoming statutes,the application shall include
recommendations from the irrigation district regarding any changes to the attached water rights and
the irrigation district's easements.If there is a conflict with the irrigation district's recommendations,
the subdivider shall certify that it met with and made a good faith effort to resolve any conflicts with
the irrigation district;and
(E)If the subdivision will create a significant additional burden or risk of liability to the public entity,
company,association or appropriators responsible for the ditch,irrigation works or other water
conveyance system,the subdivider shall provide an adequate and responsible plan to reduce or
eliminate the additional burden or risk of liability and evidence that the subdivider submitted the
plan to the public entity,company,association or appropriators for review and recommendation
regarding the adequacy of the plan.
In all correspondence regarding this application,please reference “State Engineer Subdivision Review
Number 2023-11-12”.
