GENERAL LOCATION AND DESCRIPTION
LOCATION
The Spanish Fox Estates PUD project is located within the south half of Section 19, Township 4
North, Range 68 West, in Weld County. The project property is one-half mile south of Highway
56, immediately west of Weld County Road 3, and 3 miles west ofI-25. The property is contiguous
to Town of Berthoud limits along its north property line and portions of its south property line. A
vicinity map is provided as Figure 1. The project is located within an urbanizing drainage area.
The property's southern boundary is approximated by the frequent flow channel of the Little
Thompson River. The Rockwell Ditch crosses the property just north of the Little Thompson River
plain. All proposed lots will be to the north of the Rockwell Ditch so that the ditch will be located
entirely within an open space portion of the property that will not be included with the subdivision.
DESCRIPTION OF PROPERTY
The project is a proposed 9 -lot subdivision of two parcels owned by Lawrence and Jacquelyn
Bebo. The largest parcel is #106119000039, at 105.139 acres, according to Assessor records. This
parcel has an existing home, addressed as 572 County Road 42.5. The second parcel,
#106119400081, is 19.827 acres in area and contiguous to the east of the first parcel. Thus, the
two parcels total 125.0 acres. Both parcels are currently zoned A (Agricultural), and are currently
used to farm hay.
A subdivision of the two parcels into nine residential lots is proposed, in keeping with the
agricultural and rural residential character of the surrounding area. The existing home would be
located on one of the proposed lots; eight residential lots would be added. Lot areas would range
from about 5.3 to 8.6 acres. A remainder portion of approximately 58 acres is proposed for
continuing agricultural use.
EXISTING SOILS AND VEGETATION
Seven soil classifications for the two parcels that comprise the application have been identified by
the Natural Resources Conservation Service. Table 1 lists the soil classifications, approximate
percentage of the total project area, general location within the project, and hydrologic soil group.
The hydrologic soil group is a classification of the infiltration/runoff potential of a soil: Group A
soils readily infiltrate, and Group D soils readily run off, Group B and C soil runoff characteristics
lie in between. The Weld loam, Colby loam, Otero sandy loam (5 to 9 percent), and the Tassel fine
sandy loam are the predominant soil types over the portion of the property where the proposed
residential lots will be located (the NRCS soil map is provided in the Appendix).
Existing vegetation on the property is primarily native grass. A large number of evergreen trees
have been planted on either side of the existing driveway, around the existing home, and near the
pond that is located in the south-central portion of the property.

EXISTING GROUNDWATER CONDITIONS
roundwater in the site vicinity is associated with the alluvial aquifer of the Little Thompson
River. Groundwater depths according to Soilogic, Inc. are expected to range from 5 to 10 feet
near the Little Thompson River and from 10 to 20 feet in the area proposed for development.
These are estimated depths to groundwater not based on geotechnical drilling.
DRAINAGE BASINS AND SUB -BASINS
MAJOR DRAINAGE BASIN
The project site lies in the Little Thompson River basin (Figure 1), approximately 2 miles
downstream of its confluence with Dry Creek. The Little Thompson River's headwaters lie in the
foothills south and east of Estes Park, CO. The Little Thompson continues flowing east -
northeastward from the property, joining the Big Thompson near Milliken, CO, approximately 12
miles to the east. In the property vicinity, the watershed is relatively flat, draining primarily
agricultural land.
The project area is not known to be addressed in any Weld County Master Drainage Plan, but,
being located within the Town of Berthoud Growth Management Area, is located with the area
covered by the Town of Berthoud's Storm Drainage Master Plan. The site is within what is called
the "56" basin, a primarily agricultural basin with Highway 56 traversing its center. The Berthoud
Master Plan calls for future development within this basin to detain and release stormwater runoff
at historic levels.
The Little Thompson River floodplain is located within the boundaries of the larger parcel that
will comprise the PUD. A floodplain map, FIRM 14 080266 0725 C, is included with the
appendices, with approximate property limits depicted. None of the 9 residential lots will be
located within the floodplain all of the floodplain will be located on the agricultural portion of
the property. The floodplain is also depicted on the Change of Zone plat.
Page 5
8/24/2018
SUB -BASIN DESCRIPTION
The proposed project is not located within an identifiable sub -basin. Property runoff flows
generally southeastward to the river plain as sheet flow. Figure 2 depicts flow patterns on the site
and in the immediate vicinity of the site. Photograph 1 depicts typical surface conditions that
produce a shallow non -concentrated runoff pattern. A northwest- to southeast -trending ridge lies
approximately 200' to 400' west of County Road 3. Runoff from the very small basin
(approximately 7 acres) east of this ridge flows east toward County Road 3. Flow within the
County Road 3 right-of-way flows in the western roadside swale south to the Little Thompson
River.
Photograph 1. Runoff flows from right to left as sheet flow.
A second gentle ridge is located at the property's north boundary (Photograph 2). In the photograph
the proj ect site is to the right side, and property north of the project site is to the left side. To the
north of this ridge, and off site, the terrain slopes northeastward. Regional runoff north of the
property flows away from the property toward Highway 56 and a broad drainage way that trends
eastward before turning south toward the river. Runoff from off -site property to the north therefore
does not affect the property.
Similarly, runoff from property on the other three sides of the project site does not drain toward
the project site. To the west, runoff flows south toward the Little Thompson River. To the east,
runoff flows eastward and away from the project site. To the south, runoff drains to the river.
Page 6
8/24/2018
A broad drainage way exists on the western third of the property in which concentrated flow may
occur (Photograph 3). All proposed residential lots will be located east of this drainage.
Photograph 2. Road along north property line sits on gentle ridge.
Photograph 3. Western third of property and drainage swale toward river.

DRAINAGE DESIGN CRITERIA
The site will be evaluated and site design will be based upon the Weld County Storm Drainage
Criteria Manual, Urban Drainage and Flood Control District (TJDFCD) Storm Drainage Criteria
Manual and corresponding design aids, and applied civil engineering science appropriate for the
site's characteristics.
REGULATIONS
Site runoff will be evaluated and site design will be based on the Weld County Storm Drainage
Criteria and current Weld County Code. No deviation from the Weld County Storm Drainage
Criteria is proposed for the project. A request for waiver of detention requirement is included in
this report.
DEVELOPMENT CRITERIA REFERENCE AND CONSTRAINTS
As mentioned above, the project area is not known to be addressed in any Weld County Master
Drainage Plan, but is located with the area covered by the Town of Berthoud's Storm Drainage
Master Plan. The project site is within the "56" basin, a primarily agricultural basin with Highway
56 traversing its center. The Berthoud Master Plan calls for future development within this basin
to detain and release stormwater runoff at historic levels.
The site experiences few constraints in drainage evaluation and design. Its topographic
characteristics are ideal —the locations of ridges and drainage pathways result in no off -site runoff
to the property. With the exception of a small basin at the eastern margin of the property, the
property drains directly to the Little Thompson River.
Moreover, given the historic and current primarily agricultural use of the property, and limited
basin size, site runoff is primarily sheet flow. No identifiable channels or concentrated flow paths
were observed in the portion of the property proposed for development.
Site slopes begin at a gentle approximate one percent before steepening to approximately 5 to 10
percent as the site topography transitions from agricultural plain to river bottom.
HYDROLOGICAL CRITERIA
Proj ect site runoff derives from six sub -basins (see Figure 3 and the full-size Drainage Map
provided in the map pocket). Sub -basin areas range from about 3.5 to 20.4 acres; all are less than
the 160 -acre basin area threshold under which the Rational Method is typically used for evaluating
peak discharge from design rain storms. Thus, the Rational Method was used for the project in
predicting runoff. Runoff was estimated for the 10 -year, 1 -hour (minor) and 100 -year, 1 -hour
(major) storms.
Page 8
8/24/2018
The site is located west of I-25, approximately 6 miles north of Highway 66 and the northeast
corner of Longmont. One -hour precipitation depths of 1.38 inches and 2.68 inches for the 10 -year
and 10 -year storms, respectively, were selected for use in hydrologic analysis. Both values were
taken from NOAA Atlas 14 Volume 8.
Application of the Rational Method to the site's six sub -basins requires inputs that describe or
pertain to sub -basin geometry and sub -basin infiltration parameters. Table 2 presents this
information. Peak discharges for the minor and major storms were calculated with UDFCD
spreadsheet tool, under both existing and proposed development conditions, and are presented in
the appendix. Table 3 summarizes the results of this analysis, and a more complete summary table
of Rational Method inputs is provided in the appendix.

Area -weighted runoff coefficients were used in calculating peak discharges, using approximations
of roof, street/driveway, lawn and meadow areas. Under the historic condition, the existing home
and driveway provide impervious area. Under the developed condition, for the sole purpose of
hydrologic computations, we assumed that each new home would have a 5,000 square -foot
footprint, a paved driveway that would be 15 feet wide and 200 feet long, and lawn area of '/4 -acre.
Resulting peak discharges as predicted with the Rational Method are listed in Table 3.

As can be seen from Table 3, the increase in the 100 -year, one -hour peak discharge from existing
to developed conditions is under 10 percent for all six of the project site's sub -basins. That this
increase is slight is due to the relative size and rural density of the proposed lots, which will range
from approximately 5.3 to 8.6 acres. The spreadsheet calculations summarized in Tables 2 and 3
are presented in the appendix. Additionally, runoff from the site occurs across the six basins,
without localized, point discharge outfall locations as would occur with detention pond use.request
Page 9
8/24/2018
HYDRAULIC CRITERIA
As mentioned above, the site expenences no appreciable off -site runoff to the property and is
proposed with large lots. Resulting increases in peak runoff during the major storm are under 10
percent for all six project sub -basins. As discussed in more detail below, the objective of site
development is to promote the continuation of sheet flow conditions after site development. Thus,
no detention pond or culverts, and very limited use of roadside swales, is proposed with the
development. A single swale at the southeast side of the proposed Spanish Fox Court, with a riprap
check dam/spreader wall at the swale terminus intended to re-establish sheet flow conditions as
much as reasonable.
DRAINAGE FACILITY DESIGN
Residential lots will be few and large, and changes to total impervious area within the developed
portion of the property will be minimal. Moreover, a low ridge runs generally along the north
property line, directing off -site runoff away from the project site, and runoff from the majority of
the project site flows directly into the Little Thompson River. Existing drainage patterns promote
non -erosive sheet flow and post -development conditions are proposed to maintain these historic
runoff patterns. The applicant has lived on the property since 2001, and in 17 years the sides of the
existing paved driveway are observed to have experienced little significant erosion. Thus, the
intent of drainage design is to forego roadside swales in lieu of replicating existing primarily sheet
flow runoff conditions across the entire project property.
GENERAL PROPOSED CONCEPT
Runoff from the site has historically flowed as sheet flow south toward the Little Thompson River
plain. The attached Figure 3 and the Drainage Map show runoff patterns on the project site. North
of the property line, runoff is directed toward the east-northeast. Sub -basin 101, approximately 7
acres in area, also flows eastward. The remainder of the property flows southward toward the Little
Thompson River. Site observation indicates that runoff from the portion of the site proposed for
subdivision flows as sheet flow. In this area, ground slopes range from approximately 0.75 to 1.0
percent. Photographs 1 through 3 depict this area. These plains are located in the northern two-
thirds of the property. To the south, the agricultural plains transition to steeper slopes, ranging
from approximately 5 to 10 percent, which transition to the Little Thompson River valley bottom
and floodplain.
Stormwater drainage under developed conditions will be allowed to follow historic drainage
patterns to the river. Sheet flow conditions, rather than concentrated flow, will be encouraged
under developed conditions to continue to limit erosion potential. The predicted increase in post -
development runoff under normal conditions is expected to be minimal since the overall increase
in impervious area will be relatively small. Under major storm conditions, Rational Method
calculations as listed in Table 3 indicate increases in short-term, peak conditions to be less than 10
percent over existing conditions. Additionally the timing of peak runoff from the subdivision
would not typically align with the timing of flood peaks in the Little Thompson River. The time
to peak runoff from storms over the subdivision drainage would be relatively short, typically on
Page 10
8/24/2018
the order of tens of minutes. Flood conditions in the overall Little Thompson River basin typically
result from general storms, like the September 2013 event, or from thunderstorms over several
square miles, with times to peak runoff in excess of one hour.
Limited modification to grading in the vicinity of the existing driveway and the proposed
subdivision roads is proposed. Limited roadside swales will be excavated to promote concentrated
flow. Rather, sheet flow across non -crowned roads will be promoted (see Photograph 4).
No offsite runoff will affect the site and no variance from Weld County Storm Drainage Criteria
is requested. However, a waiver of detention requirements is requested herein.
Photograph 4. Existing driveway: runoff is sheet flow from right to left.
REQUESTED WAIVER OF DETENTION REQUIREMENTS
A waiver of detention requirements is requested based on Exception 1.a.7. The waiver is based on
site stormwater runoff conditions and based on the design of the proposed PUD. No stormwater
from offsite sources runs on to the property; the north property line is the basin divide. Site runoff
flows as sheet flow generally to the south and southeast to the Little Thompson River and exits the
property thereby. No drainage problems have been noted with the property.
Nine lots will result from the proposed PUD. All lots are greater than 4.0 acres in area. Runoff
flows via overland flow and not toward roadways; therefore, roadway drainage criteria are not
exceeded. Impervious area for the developed site basins are shown in Table 2. All basin impervious
area percentages under developed conditions are less than 10%.
Page 11
8/24/2018
SPECIFIC DETAILS, ROADWAY
The proposed road surface within the project site will be an overlay of the existing driveway to
result in a 26 -foot paved width. The intent will be to promote road runoff with a crown; however,
the existing driveway profile will be maintained, with minor deviation to meet vertical curve
design conditions. Runoff will overtop the road, with the road surface acting to keep flow dispersed
and to continue to promote sheet flow. However, the road will create a slight "speed bump" to
sheet flow that encounters it. Consequently, lower lying areas will experience shallow ponding
during more intense rainstorms. These ponds will be generally less than about six inches to a foot
in depth, and will infiltrate rapidly post -storm. Two low points have been designed in the road
profile: just to the north and to the west of the intersection of the two on -site roads. These ponding
areas are few, contributing drainage areas are relatively small, ponding areas do not accept off -site
runoff, and the resulting condition will achieve the objective of promoting sheet flow. Therefore
the presence of shallow ponding is a preferred drainage condition to alternatives that may gather
dispersed flow and release it in a concentrated flow condition. Thus, limited roadside swales and
no culverts are proposed. Additionally, significant maintenance of the road or adjacent landscaping
is not anticipated to be required because storms producing runoff will be relatively infrequent and
the volume of expected ponding will be small.
SWALE DESIGN
The single proposed swale will be located southwest of the cul-de-sac bulb in the proposed Spanish
Fox Court, and will carry flow along two property lines for a distance of approximately 250 feet.
At the swale terminus a riprap check dam/level spreader will be installed to return the flow pattern
to sheet flow conditions. The riprap level spreader will be located at a natural drainage divide,
which will also serve to spread the runoff. Swale design is summarized in Table 4.

MAINTENANCE PLAN
Maintenance of the project swale and the grassed portion of the right-of-way will be performed by
the common association to be created for the proposed PUD. The association, or its agent, will
perform annual inspections. The inspection will identify areas of erosion and propose needed
repairs. Such repairs might include removal of sediment or debris, repairing erosion, and/or re-
establishing vegetation. Where vegetation is to be re-established, topsoil will be imported as
needed, the area seeded with a native seed mixture, and stabilized with a straw mulch blanket.

CONCLUSIONS
COMPLIANCE WITH THE WELD COUNTY CODE
Design of the site as proposed will be in compliance with the Weld County Code, and particularly
Section 24-7-120.
DRAINAGE CONCEPT
Residential lots will be few and large, and changes to total impervious area within the developed
portion of the property will be minimal. Moreover, a low ridge runs generally along the north
property line, directing off -site runoff away from the project site, and runoff from the majority of
the project site flows directly into the Little Thompson River. Existing drainage patterns promote
non -erosive sheet flow and post -development conditions are proposed to maintain historic runoff
patterns.
The proposed drainage design will effectively control potential damage from storm runoff. The
proposed project will not have an effect on any Weld County Master Drainage Plan
recommendations and will have a negligible effect on the volume of runoff to the Rockwell Ditch.

MAP INFORMATION
The soil surveys that comprise your AOl were mapped at 1:24,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil line
placement. The maps do not show the small areas of contrasting
soils that could have been shown at a more detailed scale.
Please rely on the bar scale on each map sheet for map
measurements.
Source of Map: Natural Resources Conservation Service
Web Soil Survey URL: http://websoilsurvey.nros.usda.gov
Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more accurate
calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as of
the version date(s) listed below.
SoilSurvey Area: Weld County, Colorado, Southern Part
Survey Area Data: Version 12, Jan 3, 2014
Soil map units are labeled (as space allows) for map scales 1:50,000
or larger.
Date(s) aerial images were photographed: Apr 22, 2011 Apr 13,
2012
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor shifting
of map unit boundaries may be evident.

Final Plan
Statement of Compliance
Introduction
The following Statement of Compliance for the Spanish Fox Estates PUD addresses the criteria set forth
in the Change ?fz0 Spanish Fox Estates is a proposed 9 -lot Planned Unit Development (PIJD), with
rural estate residential uses. Eight residential lots will be added to an existing lot. Lot sizes will range
fro 4.0 to 8.7 acres, with a remainder parcel, Tract A, totaling 58.8 acres, which will remain in
agricultural use. The project is located cast of the Town of Berthoud, one-half mile south of Highway 56,
and immediately to the west of County Road 3. Access to Spanish Fox Estates PUD will be from County
Road 3.
Compliance
Spanish Fox Estates PUD is in compliance with the criteria set forth in the Change of Zone for the
property. The PUD was designed to adhere to Weld County's Development Guide. The PUD includes an
open space casement for the common use and enjoyment of the residents and guests of Spanish Fox
Estates. A more detailed demonstration of adherence to the Development Guide is provided later in this
Statement.
Description of Uses
The following Development Guide narrative addresses the requirements of Article VI of Chapter 27 of
the Weld County Code. Spanish Fox Estates is a proposed 9 -lot rural estate subdivision, with eight
residential lots to be added to an existing lot, and a large open tract on the western half of the property.
Lot sizes will range from 4.0 to 8.7 acres, with an open tract, Tract A, totaling 58.8 acres, which will
remain in agricultural use. The large lots will allow for ample view corridors toward the west and south.
Existing irrigation and utility uses in easements will remain and will be unaffected by the PUD.
The PUD will be accessed from County Road 3 at the same location as the paved driveway to the existing
home. The driveway will be removed and replaced with a County -standard rural local road. In
constructing the road existing landscaping will remain undisturbed to the extent practicable. The PUD
uses have been selected to be appropriate to the property, surrounding land uses, topography including the
Little Thompson River valley and regulatory floodplain, and has been designed to adhere to the County's
Development Guide.
Development Guide, Component One - Environmental Impacts
1. Noise and vibration
The application proposes a PULE with 9 large residential lots in keeping with the agricultural and rural
residential character of the surrounding area. The existing home would be located on one of the
proposed lots; eight residential lots would be added. Lot areas would range from about 4.0 to 8.7
acres. Noise levels will be consistent with ordinary residential uses, including outdoor lawn mowing,
and similar residential landscaping actvities. Lot size will allow ample distance for local noise levels
to diminish at the lot lines.
Spanish Fox Estates
PUD Statement Page 2 of 7
2. Smoke, dust and odor
Levels of smoke, dust and odor will be consistent with ordinary residential uses, including typical
activities such as outdoor cooking and landscape maintenance. Lot size will allow ample distance for
dust or odors generated to diminish at the lot lines.
3. Heat, light and glare
The application proposes 9 large residential lots. Lighting will be at a residential level, with primarily
indoor lighting, and outdoor lighting provided for safety and navigation as approved by subdivision
covenants.
4. Visual/aesthetic impacts
The design of the homes and any outbuildings allowable in the Estate Zoning uses will be consistent
with the scope of surrounding land uses and rural estate residences. Proposed lots are large and will
largely maintain view corridors to the west and south.
5. Electrical interference
Installed electrical services will be at the residential scale. No modification to electrical distribution
infrastructure will be required with Spanish Fox Estates PUD.
6. Water pollution
Residential lots will be few and large, and changes to total impervious area within the
developed portion of the property will be minimal. Existing drainage patterns promote non -
erosive sheet flow and post -development conditions are proposed to maintain these historic
runoff patterns. Home sites will be located on the upland, flatter portions of the property,
maintaining existing vegetated conditions along the steeper slopes that transition to the river
plain. Existing vegetation will act as a grass buffer to limit erosion potential; the length of
this natural grass buffer will be approximately 600 feet or longer. Thus, pollution to the Little
Thompson River associated with erosion will be limited.
7. Wastewater disposal
Sewage disposal will be provided by individual septic disposal systems, designed on a lot by lot basis
at the building permit stage. Site geotechnical investigations completed by Soilogic, Inc. indicate that
"the site soils would be expected to exhibit percolation rates supporting conventional septic system
construction. Mounded systems could be considered in areas of shallow bedrock," where encoun-
tered.
8. Wetland removal
No wetlands exist in the portion of the site proposed for lot development. All lots are proposed to be
located north and outside the plain of the Little Thompson River, on the upland portions of the
property.
Spanish Fox Estates
PUD Statement Page 3 of 7
9. Erosion and sedimentation
Residential lots will be few and large, and changes to total impervious area within the
developed portion of the property will be minimal. Existing drainage patterns promote non
erosive sheet flow and post -development conditions are proposed to maintain these historic
runoff patterns. Stormwater drainage under developed conditions will be allowed to follow
historic sheet flow conditions. Concentrated flow conditions will be avoided in site
development planning to continue to limit erosion potential.
10 Excavating, filling and grading
Excavation activities will be consistent with road improvements, utility installation, and construction
of individual residences.
11. Drilling, ditching and dredging
Drilling and ditching, consistent with installation of utilities and construction of foundations for
individual residential uses, will be temporary during the construction process.
1.2. Air pollution
The application proposes 9 large residential lots. Air pollution will be minimal and limited to typical
air pollution generated at a residential level, Including automobile and lawn maintenance equipment
usage.
13. Solid waste
Individual home owners will provide acceptable household waste containers and containers for
recycling qualified materials for temporary storage of household solid waste, as accepted by local
sanitation services companies. It is expected that a single trash hauler will be selected to minimize
trips and road impacts associated with solid waste haulage, and to limit the number of days that trash
containers would be visible at the local street.
14. Wildlife removal
Spanish Fox Estates PUD will be located on land that is currently agricultural, adjacent to a river
bottom. The Little Thompson River provides a wildlife corridor that will not be impacted by the
proposed residential lots. No removal of wildlife individuals during construction of utilities, road
provements and individual residences is anticipated.
15. Natural vegetation removal
Removal of vegetation will be limited to i at area to be disturbed/improved for house and yard
footprint, and for road and driveway access.
16. Radiation/radioactive material
No radiation or radioactive material will be introduced through the development of the proposed PUD
beyond that typically produced by household uses.
Spanish Fox Estates
PUD Statement Page 4 of 7
17. Drinking water source
Potable water will be provided by the Little Thompson Water District. A commitment to serve letter
prepared by LTWD dated May 31, 2016 was provided with the Change of Zone submittal materials.
The water main that will serve the property, extending from County Road 3 to County Road 1 and
following the alignment of the proposed roads, was installed in late 2017.
18. Traffic impacts
Traffic and roadway impacts are addressed in the traffic narrative prepared by Gene Coppola and
were included with the Change of Zone submittal. The narrative concluded, "No auxiliary lane
improvements will be warranted by the (Spanish Fox Estates) development. This was determined by
comparing site traffic at the access to CR 3 and the County's numerical turn lane warrants. Turn lanes
will not be needed with this development since site traffic will not impede through traffic and the
number of peak hour turning vehicles will be below ... County triggers for higher speed roadways. In
summary, the (Development) is not expected to adversely impact the area street system. It is
considered viable from a traffic engineering perspective."
Development Guide, Component Two - Service Provision Impacts
1. Schools
The proposed 9 -lot Spanish Fox Estates PUD will be located in Thompson School District RE -2J,
which did not comment on the Sketch Plan of Change of Zone submittals. The number of potential
students to the district is limited by the small number of additional lots (8) proposed.
2. Law enforcement
Spanish Fox Estates PUD will be served by the Weld County Sheriff's Department, which did not
comment on the Sketch Plan or Change of Zone submittals.
3. Fire protection
Spanish Fox Estates PUD will be located in the Berthoud Fire Protection District, which did not
comment on the Sketch Plan or Change of Zone submittals. The number of homes added to the
district (8) by the PUD is a relatively small number.
4. Ambulance
Emergency services to Spanish Fox Estates PUD will be provided by the Berthoud Fire Protection
District, which did not comment on theSketch Plan or Change of Zone submittals. The number of
homes added to the district (8) by the PUD is a relatively small number.
5. Transportation
Traffic and roadway impacts are addressed in the traffic narrative prepared by Gene Coppola and
included with the Change of Zone submittal. The narrative concluded, "in summary, the (Develop-
ment) is not expected to adversely impact the area street system. It is considered viable from a traffic
engineering perspective."
Spanish Fox Estates
PUD Statement Page 5 of 7
6. Traffic impact analysis
A traffic narrative was prepared by Gene Coppola for the Sketch Plan submittal and was included
with the Change of Zone submittal.
7. Storm drainage
Stormwater drainage will be allowed to follow historic drainage patterns to the adjacent Little
Thompson River. Sheet flow, as currently exists, will be encouraged so that soil erosion potential is
minimized. No detention is proposed for the subdivision. Lot sizes are large and overall increases in
the percentage of impervious area will be less than 10 percent. Any increase in post -development
runoff thus is expected to be minimal. Additionally the timing of peak runoff from the subdivision
would not typically align with the timing of flood peaks in the Little Thompson River; storm
durations producing peak flows in the subdivision drainage would be entirely different from that of
the Little Thompson River drainage.
8. Utility provisions
Existing irrigation and utility easements will remain. The PUD will be served by Poudre Valley REA.
The developer installed electric utilities in late 2017 and early 2018 in utility easements as depicted
on the Final PUD Plat.
9. Water provisions
Potable water will be provided by the Little Thompson Water District. A commitment to serve letter
prepared by LTWD dated May 31, 2016 was provided with the Change of Zone submittal materials.
The water main that will serve the property, extending from County Road 3 to County Road 1 and
following the alignment of the proposed roads, was installed in late 2017.
10. Sewage disposal provisions
Sewage disposal will be provided by individual septic disposal systems, designed on a lot by lot basis
at the building permit stage.
11. Structural road improvements plan
No adjacent roadway improvements to County Road 3 will be required with the proposed PUD. The
existing driveway will be removed and a new road built to the cross section of the standard Weld
County rural local road, with the exception of the roadside swale portion of the standard section. The
intent will be to promote road runoff with a crown; however, the existing driveway profile
will be maintained with the new roadway profile, with minor deviation to meet vertical curve
design conditions. Runoff will overtop the road, with the road surface acting to keep flow
dispersed and to continue to promote sheet flow. The road section will be 3 inches of asphalt over
6 inches of base based on a geotechnical chnic al report prepared by CDS Engineering Corporation, submitted
with this Final Plan application.

PUD Statement Page 6 of 7
Development Guide, Component Three - Landscaping Elements
1. Landscape plan
Individual lots will be landscaped by the homeowner. Existing landscaping within the right-of-way
for the PUD roads and along County Road 3 will remain with completion of the subdivision, and
where located within right-of-way will be maintained by common association.
2. Buffering and screening
The PUD will include only low intensity uses, and large percentages of undeveloped spaces.
Buffering or screening of uses is not required.
3. Maintenance schedule
Existing landscaping within the right-of-way and along County Road 3 will remain after completion
of the subdivision, and where located within right-of-way will be maintained by common association
on a schedule appropriate for maintenance of grass and trees.
4. On -site improvements agreement
An agreement for managing and maintaining common landscaping is provided with the final plan.
5. Adequate water
Evidence of adequate water to sustain the landscaping will be provided with the final plan.
Development Guide, Component Four - Site Design
1. Unique features
The PUD is for nine large residential lots, in keeping with the agricultural and rural residential
character of the surrounding area. The existing home would be located on one of the proposed lots;
eight residential lots would be added. Lot areas would range from about 4.0 to 8.7 acres. The layout
of the eight new lots was selected to take advantage of unique features of the site. A 58.8 -acre
agricultural tract (Tract A) will remain after the subdivision, providing view corridors to the west,
separation from uses near County Road 1, and maintaining agricultural uses immediately adjacent to
the proposed lots. Lots were chosen so that home sites could be placed on the flatter portions of the
property, north of the 5 to 10 percent slopes that fall toward the Little Thompson River flows at the
southern margin of the property. All lots are located north of the Rockwell Ditch so that there will be
no conflict with ditch access or maintenance, and the ditch will be located entirely inside Tract A. All
lots are located outside of the Little Thompson River floodplain, as shown on the Change of Zone
Plat. An open space easement is provided with the PUD plat. The open space easement will be for the
common use and enjoyment of the residents and guests of Spanish Fox Estates.
2. PUD rezoning consistency
Spanish Fox Estates, as designed with 9 large residential lots and a 58.8 -acre open tract, will be
consistent with the surrounding agricultural land uses and the natural resources provided by the Little
Thompson River corridor. Lots were sized and located to respect these objectives.
Spanish Fox Estates
PUD Statement Page 7 of 7
3. Allowed uses
Eight single family residential units are proposed in addition to the existing home. Outbuildings will
be allowed consistent with the rural residential character of the subdivision, to be defined per the
covenants, consistent with uses allowed in the Estate Zoning District.
4. Use compatibility
The proposed single family, large -lot residences proposed with the PUD arc compatible with existing
agricultural and estate development that surrounds the property. The shooting range (Berthoud Gun
Club) is a trap range to the west of the property, and the Town of Berthoud wastewater treatment
facility is located to the southwest. Both are uses that are within the margin of compatibility with the
proposed large -lot residences. However, separation from these two facilities is provided by placing
the eight new lots to the east. Tract A is a 58.8 -acre tract that provides a buffering distance from these
uses. The Berthoud Gun Club is located approximately one-half mile from the nearest proposed lot.
5. Hazards or overlay zones
All of the proposed residential lots will be located outside the Little Thompson River floodplain. The
property is not in a geologic hazard zone or airport overlay district.
Development Guide, Component Five - Common Open Space Usage
The PUD is considered urban scale due to its proximity to the Town of Berthoud, and will provide an
open space easement to allow residents and guests of the community to walk throughout the
community, including into Tract A and around the existing pond. Lot sizes arc large (4.0 to 8.7 acres),
allowing for ample open space also on each lot. Additionally, the 58 -acre open space to the west,
Tract A, allows for views westward and a sense of openness in the subdivision area. Site design has
emphasized existing view corridors already enhanced by landscaping planted by the land owner.
Development Guide, Component Six - Signage
Signage for the proposed Spanish Fox Estates PUD will be installed at the entry to the subdivision
from County Road 3. S ignag e will be in accordance with the sign regulations of Chapter 23, Article
IV, Division 2.
Development Guide, Component Seven - RUA Impact
Spanish Fox Estates PUD is not located within any of the three current Regional Urbanization Areas
(RDAs), which include the 1-25 RUA, the Southeast Weld RUA, and the Dry Creek RUA.
Development Guide, Component Eight - Intergovernmental Agreements
No impact upon intergovernmental Agreements or other formal or informal understandings between
Weld County and the Town of Berthoud is anticipated. In review of the Sketch Plan submittal, the
Town indicated that they could see no conflicts in the proposed P.U.D. subdivision.
