17. Describe the existing and proposed fencing and screening for the site including all
parking and outdoor storage areas.
The existing trees on the property and surrounding properties provide sufficient screening,
as shown on the site plan included with the application materials. As the parking area will
not be visible from public road right-of-way, no additional screening is proposed.
To enhance compatibility with neighboring properties, care will be taken to maintain the
native grass between and around parked vehicles and equipment.
18. Describe the existing and proposed landscaping for the site.
See answer to item 17 above.
19. Describe reclamation procedures to be employed as stages of the operation are phased

Page 5 of 9
Upon cessation of the Use by Special Review activity, equipment specific to the business
will be removed. The existing structures will remain for residential or agricultural use.
20. Describe the proposed fire protection measures.
Fire protection for the site is provided by the Galeton Fire Protection District.
21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per
Chapter 22 of the Weld County Code.
The proposed USR makes beneficial use of the 0.75 -acre portion of the site that is split from
the rest of the property by the Eaton Ditch. This allows the continued use of the property
west of the Eaton Ditch for crop farming, livestock grazing and residential uses. This
preserves agricultural areas, which is consistent with the following section of the
Comprehensive Plan:
Sec. 22-2-60.B. Support responsible energy and mineral development.
5. Energy development facilities should preserve agricultural areas and enhance the
rural landscape.
The Comprehensive Plan also recognizes mineral resources as vital to the State's economy.
Oil and gas support services businesses are necessary for mineral resource development in
Weld County. Appendix 22-C contains the following Right to Extract Mineral Resources
Statement:
Weld County has some of the most abundant mineral resources, including, but not
limited to, sand and gravel, oil, natural gas, and coal. Under Title 34 of the Colorado
Revised Statutes, minerals are vital resources because (a) the state's commercial
mineral deposits are essential to the state's economy; (b) the populous counties of the
state face a critical shortage of such deposits; and (c) such deposits should be extracted
according to a rational plan, calculated to avoid waste of such deposits and cause the
least practicable disruption of the ecology and quality of life of the citizens of the
populous counties of the state.
Mineral resource locations are widespread throughout the County and people moving
into these areas must recognize the various impacts associated with this development.
Often times, mineral resource sites are fixed to their geographical and geophysical
locations. Moreover, these resources are protected property rights and mineral owners
should be afforded the opportunity to extract the mineral resource.
22. Explain how this proposal is consistent with the intent of the zone district in which it is
located. (Intent statements can be found at the beginning of each zone district section
in Article Ill of Chapter 23 of the Weld County Code.)
Energy development is supported in the A Zone District per Sec. 23-3-10. Intent:
Agriculture in the COUNTY is considered a valuable resource which must be protected
from adverse impacts resulting from uncontrolled and undirected business, industrial
and residential land USES. The A (Agricultural) Zone District is established to maintain
and promote agriculture as an essential feature of the COUNTY. The A (Agricultural)
Zone District is intended to provide areas for the conduct of agricultural activities and
Page 6 of 9
activities related to agriculture and agricultural production, and for areas for natural
resource extraction and energy development, without the interference of other,
incompatible land USES.
The proposed use is allowed in the A Zone District as a USR:
Sec. 23-3-40. Uses by special review outside of subdivisions and historic townsites.
oil and gas support service business.
W. Oil and Gas Support and Service.
23. Explain how this proposal will be compatible with future development of the
surrounding area or adopted master plans of affected municipalities.
The subject property is not within any coordinated planning areas or growth management
areas of any municipalities. Per the Weld County Comprehensive Plan Map, the site is
within a Non -Urban area, approximately 3/4 -mile from two Opportunity Zones. As no
subdivisions or zone changes are proposed, the Non -Urban classifications and proximity to
Opportunity Zones are not anticipated to be applicable to this proposal.
24. Explain how this proposal impacts the protection of the health, safety and welfare of
the inhabitants of the neighborhood and the County.
The proposed use is not anticipated to produce a significant amount of dust, waste, debris,
noise, or odor. Trash will be collected in a covered and confined dumpster and removed as
needed by a trash removal company.
Development Standards established for this USR will ensure that adequate provisions are
made to protect the health, safety, and welfare of the inhabitants of the neighborhood and
the County.
25. Describe any irrigation features. If the proposed use is to be located in the A
(Agricultural) Zone District, explain your efforts to conserve prime agricultural land in
the locational decision for the proposed use.
The proposed USR makes beneficial use of the 0.75 -acre portion of the site that is split from
the rest of the property by the Eaton Ditch. This allows the continued use of the property
west of the Eaton Ditch for crop farming, livestock grazing and residential uses and
preserves agricultural areas.
26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the
proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or
Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps
officially adopted by the County.
The site is not located within any Airport, Geologic Hazard, Historic Townsites Overlay
Districts, or Special Flood Hazard Areas.
27. Detail known State or Federal permits required for your proposed use(s) and the status
of each permit. Provide a copy of any application or permit.
Page 7 of 9
No State or Federal permits are anticipated with this USR.

REVIEW:
Please submit the below listed items to the Department of Planning Services.
PLANNING COMMENTS:
The Department of Planning Services has reviewed the Completeness Review and has the
following comments.
1. Please submit a copy of this form when you submit the revisions to your Land Use
Application.
A copy of this form is included.
2. Is the total number of vehicles going to be fifteen (15) or will this increase?
As requested by Staff, gravel all-weather parking surfaces have been added to the USR Site
Plan. As a result of this site change, the total number of requested vehicles will be reduced to
fourteen (14). The revised USR Site Plan and Questionnaire are included with this re -submittal.
3. Has there been conversation in regard to the access road with the neighbors? This will be a
sticking point. If access does not work where the trucks be places elsewhere?
Conversations with the neighbors regarding the access road are ongoing. The neighboring
parcels to the east and south are owned by Rachelle and Jarrett McGraw and Estin McGraw. A
new shared road on and across these parcels has been recently constructed for the McGraw's
use.
4. What is proposed for screening of the parking area?
As stated in the USR questionnaire, the existing trees on the property and surrounding
properties provide sufficient screening, as shown on the site plan included with the application
materials. As the parking area will not be visible from public road right-of-way. no additional
screening is proposed. To enhance compatibility with neighboring properties, care will be taken
to maintain the native grass between and around parked vehicles and equipment
5. When you say "occasional operations" outside of typical operation hours what is expected
for this?
The expected primary hours of operation are 5:00 am to 8:00 pm, Monday through Friday.
Parking at the facility will occur 24 -hours per day and 7 -days per week. Occasional operations
encompasses the possible, but infrequent, situation when a truck is needed on a job site over
the weekend or a vehicle is returned after hours.
We don't want to get into a situation where an employee who gets stuck on a job site later than
expected is not able to return the vehicle the same day without potentially putting the USR
permit at risk. The same would be true for a typical office environment. The business hours at a
typical office may be 8:00 am to 5:00 pm Monday through Friday, but administrative staff may
come in earlier to open the office up or a cleaning crew may be in the building after hours.
The alternative would be to say that all operations will be 24 -hours per day and 7 -days per
week, but that would imply a heavier intensity of use than is expected.
6. Appears "natural" screening is in place for 26250 CR 70 and 26350 CR 70 but what about

from the subject property by a large pasture. There is also an existing fence along the east side
of the shared roadway. No additional screening is anticipated to be needed.

Completeness Review
PUBLIC WORKS COMMENTS:
1. The truck parking requires at a minimum water quality. A drainage report providing water
quality shall be provided. Planning has determined that an all-weather drive surface is required
for truck parking. This makes the drainage narrative of "no change in impervious" null. Please
provide a drainage narrative with valid exception to stormwater detention or a drainage report
providing detention for the improvements.
Water Quality is not required as this site is agriculture zoned land in a non -urbanizing area.
Water quality design is provided for the truck and equipment parking area east of the Eaton
Ditch, as required by Public Works to meet unwritten department policy as a condition for the
USR application to be deemed complete. While AGPROfessionals disagrees that water quality
is necessary for this USR, water quality design is provided to meet County deadlines for
acceptance of the USR application.
The site is in a non -urbanizing area and the total pre-existing and post development impervious
area produces stormwater runoff of less than, or equal to, five (5) cfs for the 1 -hour, 100 -year.
storm event, and is therefore exempt from stormwater detention per Article XI, Storm Drainage
Criteria, Section 8-11-40 Drainage Policy:
1. Exceptions to stormwater detention shall not jeopardize the public health, safety, and welfare
of public and private property. No stormwater detention will be required for sites that meet
any of the following conditions. Requirements of the Municipal Separate Storm Sewer
System (MS4) areas remain applicable. Public Works will confirm if the development qualifies
for an exception based upon the information provided by the applicant. Exceptions shall be
supported with an approved drainage narrative, which must describe at a minimum:
1. Any existing and proposed improvements to the property.
2. The exception being requested for consideration.
3. Where the water originates if it flows onto the property from an off -site source.
4. Where the water flows as it leaves the property.
5. The direction of flow across the property.
6. Previous drainage problems with the property, if any.
7. The location of any irrigation facilities adjacent to or near the property.
8. Any additional information pertinent to the development.
Exceptions to the stormwater detention shall be limited to the following uses:
9. Non -Urbanizing areas where the total pre-existing and post development impervious
area produces stormwater runoff of less than, or equal to, five (5) cfs for the 1 -hour. 100 -year
storm event. This exception shall be supported by calculations signed and stamped by a
Colorado Licensed Professional Engineer.
A revised Drainage Narrative which describes the above items, signed and stamped by a
Colorado Licensed Professional Engineer, is included with this re -submittal.
2. Additionally, AP21-00067 is not for commercial use. A new access permit will be required
before recording the USR map.

15. RIGHT TO EXTRACT MINERAL RESOURCES STATEMENT: WELD COUNTY HAS SOME OF THE MOST ABUNDANT MINERAL
RESOURCES, INCLUDING, BUT NOT LIMITED TO, SAND AND GRAVEL, OIL, NATURAL GAS, AND COAL. UNDER TITLE 34 OF THE
COLORADO REVISED STATUTES, MINERALS ARE VITAL RESOURCES BECAUSE (A) THE STATE'S COMMERCIAL MINERAL
DEPOSITS ARE ESSENTIAL TO THE STATE'S ECONOMY; (B) THE POPULOUS COUNTIES OF THE STATE FACE A CRITICAL
SHORTAGE OF SUCH DEPOSITS; AND (C) SUCH DEPOSITS SHOULD BE EXTRACTED ACCORDING TO A RATIONAL PLAN,
CALCULATED TO AVOID WASTE OF SUCH DEPOSITS AND CAUSE THE LEAST PRACTICABLE DISRUPTION OF THE ECOLOGY AND
QUALITY OF LIFE OF THE CITIZENS OF THE POPULOUS COUNTIES OF THE STATE.
MINERAL RESOURCE LOCATIONS ARE WIDESPREAD THROUGHOUT THE COUNTY AND PERSON MOVING INTO THESE AREAS
MUST RECOGNIZE THE VARIOUS IMPACTS ASSOCIATED WITH THIS DEVELOPMENT. OFTEN TIMES, MINERAL RESOURCE SITES
ARE FIXED TO THEIR GEOGRAPHICAL AND GEOPHYSICAL LOCATIONS. MOREOVER, THESE RESOURCES ARE PROTECTED
PROPERTY RIGHTS AND MINERAL OWNERS SHOULD BE AFFORDED THE OPPORTUNITY TO EXTRACT THE MINERAL RESOURCE.
NOTES CONTINUED:
16. WELD COUNTY'S RIGHT TO FARM STATEMENT: WELD COUNTY IS ONE OF THE MOST PRODUCTIVE AGRICULTURAL COUNTIES
IN THE UNITED STATES, TYPICALLY RANKING IN THE TOP TEN COUNTIES IN THE COUNTRY IN TOTAL MARKET VALUE OF
AGRICULTURAL PRODUCTS SOLD. THE RURAL AREAS OF WELD COUNTY MAY BE OPEN AND SPACIOUS, BUT THEY ARE
INTENSIVELY USED FOR AGRICULTURE. PERSONS MOVING INTO A RURAL AREA MUST RECOGNIZE AND ACCEPT THERE ARE
DRAWBACKS, INCLUDING CONFLICTS WITH LONGSTANDING AGRICULTURAL PRACTICES AND A LOWER LEVEL OF SERVICES
THAN IN TOWN. ALONG WITH THE DRAWBACKS COME THE INCENTIVES WHICH ATTRACT URBAN DWELLERS TO RELOCATE
TO RURAL AREAS: OPEN VIEWS, SPACIOUSNESS, WILDLIFE, LACK OF CITY NOISE AND CONGESTION, AND THE RURAL
ATMOSPHERE AND WAY OF LIFE. WITHOUT NEIGHBORING FARMS, THOSE FEATURES WHICH ATTRACT URBAN DWELLERS
TO RURAL WELD COUNTY WOULD QUICKLY BE GONE FOREVER.
AGRICULTURAL USERS OF THE LAND SHOULD NOT BE EXPECTED TO CHANGE THEIR LONG-ESTABLISHED AGRICULTURAL
PRACTICES TO ACCOMMODATE THE INTRUSIONS OF URBAN USERS INTO A RURAL AREA. WELL -RUN AGRICULTURAL ACTIVITIES
WILL GENERATE OFF -SITE IMPACTS, INCLUDING NOISE FROM TRACTORS AND EQUIPMENT; SLOW -MOVING FARM VEHICLES ON
RURAL ROADS; DUST FROM ANIMAL PENS, FIELD WORK, HARVEST AND GRAVEL ROADS; ODOR FROM ANIMAL CONFINEMENT,
SILAGE AND MANURE; SMOKE FROM DITCH BURNING; FLIES AND MOSQUITOES; HUNTING AND TRAPPING ACTIVITIES;
SHOOTING SPORTS, LEGAL HAZING OF NUISANCE WILDLIFE; AND THE USE OF PESTICIDES AND FERTILIZERS IN THE FIELDS,
INCLUDING THE USE OF AERIAL SPRAYING. IT IS COMMON PRACTICE FOR AGRICULTURAL PRODUCERS TO UTILIZE AN
ACCUMULATION OF AGRICULTURAL MACHINERY AND SUPPLIES TO ASSIST IN THEIR AGRICULTURAL OPERATIONS. A
CONCENTRATION OF MISCELLANEOUS AGRICULTURAL MATERIALS OFTEN PRODUCES A VISUAL DISPARITY BETWEEN RURAL
AND URBAN AREAS OF THE COUNTY. SECTON 35-3.5-102, C.R.S., PROVIDES THAT AN AGRICULTURAL OPERATION SHALL NOT BE
FOUND TO BE A PUBLIC OR PRIVATE NUISANCE IF THE AGRICULTURAL OPERATION ALLEGED TO BE A NUISANCE EMPLOYS
METHODS OR PRACTICES THAT ARE COMMONLY OR REASONABLY ASSOCIATED WITH AGRICULTURAL PRODUCTION.
WATER HAS BEEN, AND CONTINUES TO BE, THE LIFELINE FOR THE AGRICULTURAL COMMUNITY. IT IS UNREALISTIC TO ASSUME
THAT DITCHES AND RESERVOIRS MAY SIMPLY BE MOVED "OUT OF THE WAY" OF RESIDENTIAL DEVELOPEMENT. WHEN MOVING
TO THE COUNTY, PROPERTY OWNERS AND RESIDENTS MUST REALIZE THEY CANNOT TAKE WATER FROM IRRIGATION DITCHES,
LAKES, OR OTHER STRUCTURES, UNLESS THEY HAVE AN ADJUDICATED RIGHT TO THE WATER.
WELD COUNTY COVERS A LAND AREA OF FOUR THOUSAND (4,000) SQUARE MILES IN SIZE (TWICE THE SIZE OF THE STATE
OF DELAWARE) WITH MORE THAN THREE THOUSAND SEVEN HUNDRED (3,700) MILES OF STATE AND COUNTY ROADS OUTSIDE
OF MUNICIPALITIES. THE SHEER MAGNITUDE OF THE AREA TO BE SERVED STRETCHES AVAILABLE RESOURCES. LAW
ENFORCEMENT IS BASED ON RESPONSES TO COMPLAINTS MORE THAN ON PATROLS OF THE COUNTY, AND THE DISTANCES
WHICH MUST BE TRAVELED MAY DELAY ALL EMERGENCY RESPONSES, INCLUDING LAW ENFORCEMENT, AMBULANCE, AND FIRE.
FIRE PROTECTION IS USUALLY PROVIDED BY VOLUNTEERS WHO MUST LEAVE THEIR JOBS AND FAMILIES TO RESPOND TO
EMERGENCIES. COUNTY GRAVEL ROADS, NO MATTER HOW OFTEN THEY ARE BLADED, WILL NOT PROVIDE THE SAME KIND OF
SURFACE EXPECTED FROM A PAVED ROAD. SNOW REMOVAL PRIORITIES MEAN THAT ROADS FROM SUBDIVISIONS TO ARTERIALS
MAY NOT BE CLEARED FOR SEVERAL DAYS AFTER A SNOWSTORM. SNOW REMOVAL PRIORITIES MEAN THAT ROADS FROM
SUBDIVISIONS TO ARTERIALS MAY NOT BE CLEARED FOR SEVERAL DAYS AFTER A MAJOR SNOWSTORM. SERVICES IN RURAL
AREAS, IN MANY CASES, WILL NOT BE EQUIVALENT TO MUNICIPAL SERVICES. RURAL DWELLERS MUST, BY NECESSITY, BE
MORE SELF-SUFFICIENT THAN URBAN DWELLERS.
PEOPLE ARE EXPOSED TO DIFFERENT HAZARDS IN THE COUNTY THAN IN AN URBAN OR SUBURBAN SETTING. FARM EQUIPMENT
AND OIL FIELD EQUIPMENT, PONDS AND IRRIGATION DITCHES, ELECTRICAL POWER FOR PUMPS AND CENTER PIVOT OPERATIONS,
HIGH SPEED TRAFFIC, SAND BURS, PUNCTURE VINES, TERRITORIAL FARM DOGS, AND LIVESTOCK, AND OPEN BURNING PRESENT
REAL THREATS. CONTROLLING CHILDREN'S ACTIVITIES IS IMPORTANT, NOT ONLY FOR THEIR SAFETY, BUT ALSO FOR THE
PROTECTION OF THE FARMER'S LIVELIHOOD.

Traffic Narrative
The 26.73 -acre subject property is located on the east side of Weld County Road (WCR) 53
approximately 310 -feet south of WCR 70. The proposed Ditter Trucking and Oil Field
Services Use By Special Review (USR) permit for an oil and gas support service business
will allow truck and equipment parking for up to 15 vehicles on -site at one time. There is an
existing single-family residence and associated out -buildings. The existing buildings are for
personal use and are not associated with the proposed USR uses. Truck and equipment
parking will occur on the approximately 0.75 -acre area of the site east of the Eaton Ditch.
Access to the eastern portion of the site is via a shared roadway.
Ditter Trucking and Oil Field Services are a cargo and freight company serving the oil and
gas industry. Trucks that may be on -site include semi tractor -trailers and dump trucks.
Equipment that may be on -site includes trailers, excavators and loaders. Currently, there are
three semi tractor -trailers, two dump trucks, three side dump trucks, and a lowboy trailer.
The business may expand to have up to 15 vehicles parked on -site at one time, depending
on market conditions.
As the site is for parking of trucks and equipment only, no on -site employees are proposed.
Currently, there are four employees accessing this site, one of which is Stacy Ditter. The
business may expand with up to 15 employees picking-up/dropping-off vehicles on a busy
day. Drivers will be on -site for less than two hours at a time.
Access to the agricultural and residential portion of the property is located on WCR 53
approximately 950 -feet south of the intersection of WCR 70, access permit no. AP21-00067.
The existing access for the truck and equipment parking is located on WCR 70
approximately 1,315 -feet east of the WCR 53. This access is shared by Lot 2 RE -32 (Stacy
Ditter), Lot A RE -2799 (Donald and Margie Hamilton), and Lot B 2AMRECX20-95-1817
(Jarrett and Rachelle McGraw), access permit no. AP20-00328. No new access points are
proposed. Both WCR 53 and WCR 70 are local gravel roads.
Parking at the facility will occur 24 -hours per day 7 -days per week. The primary hours of
operations are 5:00 A.M. to 8:00 P.M., Monday through Friday. Occasional operations
outside of the primary hours may be required due to the oil and gas industry service needs.

Stacy E. altter — Drainage Narrative
Summary
The applicant is requesting a Use by Special Review (USR) permit for an oil and gas
support service business for truck and equipment parking. The project site for the
proposed USR is an agriculture zoned, non -urbanizing property. There are two distinct
major drainage basins that are separated by the Eaton Ditch. Drainage Basin 1, containing
approximately 25 -acres, lies west of the Eaton Ditch and includes an existing residence,
outbuildings, and agricultural field. The historical Use by Right agricultural practices in
Drainage Basin 1 will remain. Drainage Basin 2 contains approximately 0.66 -acres and is
east of the Eaton Ditch. The proposed truck and equipment parking will occur on an all-
weather gravel surface in Drainage Basin 2.
Water Quality is not required as this site is agriculture zoned land in a non -urbanizing
area. Water quality design is provided for Drainage Basin 2, as required by Public Works
to meet recent unwritten department policy.
The proj ect site is in a non -urbanizing area and the total pre-existing and post
development impervious area produces stormwater runoff of less than, or equal to, five
(5) cfs for the 1 -hour, 100 -year, storm event, and is therefore exempt from stormwater
detention per Article XI, Storm Drainage Criteria, Section 8-11-40 Drainage Policy:
I. Exceptions to stormwater detention shall not jeopardize the public health, safety, and
welfare of public and private prop erty. o stormwater detention will he required for
sites that meet any of the following conditions. Requirements of the Municipal
Separate Storm Sewer System ('MS4,) areas remain applicable. Public Works will
confirm jf the development qualifies for an exception based upon the information
provided by the applicant Exceptions shall be supported with an approved drainage
narrative, which must describe at a minimum:
1. Any existing and proposed improvements to the property.
2. The exception being requested for consideration.
3. Where the water originates if it flows onto the property from an off -site source.
4. Where the water flows as it leaves the property.
5. The direction offlow across the property.
6. Previous drainage problems with the property, if any.
7. The location of any irrigation facilities adjacent to or near the property.
8. Any additional information pertinent to the development.
Exceptions to the stormwater detention shall be limited to the following uses:
9. Non -Urbanizing areas where the total pre-existing and post development
impervious area produces stormwater runoff `of less than, or equal to, five (5,) cfs for the
1 -hour, 100 -year, storm event. This exception shall he supported by calculations signed
and stamped by a Colorado Licensed Professional Engineer.

Introduction
1. Location
The existing parcel is located in Part of the Northwest 1/4 of Section 16, Township
North, Range 64 West of the 6th P.M., Weld County, Colorado, being Lot 2 RE -32. The
project site is located directly east of County Road 53, approximately 0.1 miles south of
County Road 70, and approximately 2.5 miles southeast of the town of Galeton. All the
properties surrounding the subject property are zoned agriculture. A vicinity map is
shown in Appendix
2. Property Description
The applicant is proposing a Use by Special Review (USR) for the site, which is
approximately 26.73 acres. The site has a house, outbuildings d agricultural farmland
on the west side of the Eaton Ditch (Drainage Basin 1) and native grass on the east side
of Eaton Ditch (Drainage Basin 2). The existing 0.66 -acre native grass area on the east
side of the Eaton Ditch will be used for truck and equipment parking. There will be small
improvements to define the parking area and place improved all-weather gravel parking
areas. No changes to the west side of Eaton Ditch are proposed and stormwater detention
and water quality are not needed for the Use by Right farming activities that are currently
occurring in Drainage Basin 1.
Storrnwater detention and water quality are not needed for the Use by Special Review
activities in Drainage Basin 2 as the site is agriculture zoned land in a non-urbanzing area
and the produced stormwater runoff will be less than five (5) cfs for the 1 -hour, 100 -year,
storm event.
There is one type of soil present on the site: Thedalund loam (1-3% slopes). The soil is
well drained, hydraulic soil group C (see USDA-NRCS soil report in Appendix B).
Eaton Ditch runs on the east end of the property and splits the agricultural field and
residence from the proposed parking area.

Historic Drainage
1. overall Basin Description.
The site has shallow sloping topography with slopes from 1-3%. A topographic map was
downloaded from the United States Geological Survey USG website and is provided
in Appendix C. The USGUSGS topo map shows that the land to the west of Eaton Ditch
generally slopes toward the Eaton Ditch. However, on the project site the area with the
house, out buildings, and field slope west toward WCR 53. The area east of the Eaton
Ditch is fairly flat and appears to gently slope southeast away from the Eaton Ditch. A
final field survey will be completed to verify elevations. Since there are no proposed site
changes on the west side of Eaton Ditch, the percentage of imperviousness will not be
altered. With the addition of the parking area on the east side, the area will slightly
increase in imperviousness. Per unwritten Department of Public Works policy, water
quality design will be provided for the truck parking area. Historically, there have been
no previous drainage issues with the property.
A Federal Emergency Management Administration (FEMA) map of the project area is
included in Appendix B. The property is located on panel 08123C1575E 1 7 5E and is in an
area of Minimal Flood Hazard, Zone X.
2. Drainage Patterns Through Property
The site is in rural Weld County and is surrounded by agriculture land. A Master Plan for
the site area is not currently available. The site has shallow slopes and appears to slope
primarily west. The area east of the Eaton Ditch is fairly flat and appears to gently slope
southeast according to the USGS Topo. The USES topographic data was used for the
preliminary drainage report and plan.
3. `-site Drainage Flow Patterns
Off -site flowsrom the north and south appear to flow west paralleling the site. Off -site
flows from the west appear to flow east but are intercepted by WCR . 3. Off -site flows
from the east appear to flow southeast away from the property. Historical flow patterns
will be maintained.

Drainage Design Criteria
1. Development Criteria
The proposed runoff calculation was determined using the criteria set forth in the Urban
Drainage and Flood Control District (UDFCD) Volumes 1, 2 and 3 and the Weld County
Engineering and Construction Guidelines (WCECG) manual.
2. Hydrological Criteria
From NOAA Atlas 14 Gill, CO precipitation station, the estimated rainfall from the 100 -
year, 1 -hour precipitation is 2.68 inches (see NOAA Atlas 14 Precipitation Data in
Appendix E). This value was used for runoff calculations.
Percentage of imperviousness was determined using the recommended values from
FCD Table 6-3. The site has been divided into Irainage Basin 1, Drainage Basin 2,
off -site Basin 1 (OS -1) and Off -site Basin 2 (OS -2). The percentage of imperviousness
for each drainage basin is summarized in Table 1 below (see Percentage of
Imperviousness Calculation in Appendix F).

Using the 100 -year, 1 -hour design storm and the UDFCD etention Basin spreadsheet,
the peak runoff flowrate was estimated using the Modified FAA method. The time of
concentration was calculated using the UD-Rational v.1.02 spreadsheet. For basins under
20 -acres the "computed" time of concentration from the UD-Rational v.1.02 spreadsheet
was used. For basins over 20 -acres the "regional" time of concentration was used. The
peak runoff flowrate was calculated using the time of concentration, runoff coefficient,
and the precipitation depth in the UDFCD spreadsheet (see UDFCD Runoff Calculation
in Appendix G). The peak runoff flowrate was determined for each drainage basin.
Table 2 summarizes the drainage basins' flow rate.

OS -1 is the grass area to the south of the proposed parking area and on the east side of the
ditch. This area is too narrow for truck parking and extensive drainage infrastructure. It
will remain in native grass and not be developed, therefore, not considered in the
drainage calculations for the rain garden.
OS -2 is the gravel road to the east of Drainage Basin 2 and native grass east of the gravel
access road. The gravel access road services the neighboring properties and will be
maintained as it historically has been, and drainage direction is not proposed to change.
This area appears to drain parallel to the parking area and therefore, has not been
included in the drainage calculations for the rain garden.
The Eaton bitch is a concrete open channel ditch. The ditch was not considered as a
drainage basin as it does not contribute to runoff to the site.
3. Hydraulic Criteria
The water quality basin storage volume was calculated for Drainage Basin #2 using the
UDFCD Water Quality Capture Volume (WQCV) spreadsheet. Using the WQCV
calculations presented in Chapter 3 of UDF R , the tributary area imperviousness, and a
12 -hour drain time, the WQCV was calculated to be 230 cubic feet for the proposed track
parking area. Per UDFCD Rain Garden Design Criteria, a proposed rain garden BMPs
will capture and treat the WQCV. Rain Garden I esign calculations are presented in
Appendix I.
The Site Plan and design of the Rain Garden are located on the Drainage Map in
Appendix I.

Stacy E. Ditter — Drainage Narrative
Conclusions
This drainage narrative is consistent with the Weld County Engineering and Construction
Guidelines and the I FCD Criteria Manual. An increased risk of damage from storm
runoff is not expected as the minimal parking improvements proposed in Drainage Basin
2 produce less than five (5) cfs for the 1 -hour, 100 -year, storm event. The site is outside
of the Municipal Separate Storm Sewer System (4) boundary, is agriculture zoned and
non -urbanizing. Water quality design is provided for the proposed Uses by Special
Review as required by Public Works per current urn. -written department policy. We
recommend that the site is exempt from stormwater detention per Article XI, Storm
Drainage Criteria, Section 8-11-40 Drainage Policy.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nrcs.usda.goviwpsi
portal/nres/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.govllocator/app?agency=arcs) or your NROS State Soil
Scientist (http://www.nres.usda.govfwpslportal/nres/detaillsoils/contactusl?
aid=nres 14.2 p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other f=ederal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (N RCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the N RCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are Made
Soil surveys are made to provide information about the soils and miscellaneous
areas in a specific area. They include a description of the soils and miscellaneous
areas and their location on the landscape and tables that show soil properties and
limitations affecting various uses. Soil scientists observed the steepness, length,
and shape of the slopes; the general pattern of drainage; the kinds of crops and
native plants; and the kinds of bedrock. They observed and described many soil
profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The
profile extends from the surface down into the unconsolidated material in which the
soil formed or from the surface down to bedrock. The unconsolidated material is
devoid of roots and other living organisms and has not been changed by other
biological activity.
Currently, soils are mapped according to the boundaries of major land resource
areas (MLRAs). MLRAs are geographically associated land resource units that
share common characteristics related to physiography, geology, climate, water
resources, soils, biological resources, and land uses (USDA, 2006). Soil survey
areas typically consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that
is related to the geology, landforms, relief, climate, and natural vegetation of the
area. Each kind of soil and miscellaneous area is associated with a particular kind
of landform or with a segment of the landform. By observing the soils and
miscellaneous areas in the survey area and relating their position to specific
segments of the landform, a soil scientist develops a concept, or model, of how they
were formed. Thus, during mapping, this model enables the soil scientist to predict
with a considerable degree of accuracy the kind of soil or miscellaneous area at a
specific location on the landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented
by an understanding of the soil -vegetation -landscape relationship, are sufficient to
verify predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, reaction, and other features that enable them
to identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil
characteristics with precisely defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
classification used in the United States, is based mainly on the kind and character
of soil properties and the arrangement of horizons within the profile. After the soil
5
Custom Soil Resource Report
scientists classified and named the soils in the survey area, they compared the
individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that
have similar use and management requirements. Each map unit is defined by a
unique combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components
of the map unit. The presence of minor components in a map unit in no way
diminishes the usefulness or accuracy of the data. The delineation of such
landforms and landform segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, onsite
investigation is needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape,
and experience of the soil scientist. Observations are made to test and refine the
soil -landscape model and predictions and to verify the classification of the soils at
specific locations. Once the soil -landscape model is refined, a significantly smaller
number of measurements of individual soil properties are made and recorded.
These measurements may include field measurements, such as those for color,
depth to bedrock, and texture, and laboratory measurements, such as those for
content of sand, silt, clay, salt, and other components. Properties of each soil
typically vary from one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area generally
are collected for laboratory analyses and for engineering tests. Soil scientists
interpret the data from these analyses and tests as well as the field -observed
characteristics and the soil properties to determine the expected behavior of the
soils under different uses. Interpretations for all of the soils are field tested through
observation of the soils in different uses and under different levels of management.
Some interpretations are modified to fit local conditions, and some new
interpretations are developed to meet local needs. Data are assembled from other
sources, such as research information, production records, and field experience of
specialists. For example, data on crop yields under defined levels of management
are assembled from farm records and from field or plot experiments on the same
kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on
such variables as climate and biological activity. Soil conditions are predictable over
long periods of time, but they are not predictable from year to year. For example,
soil scientists can predict with a fairly high degree of accuracy that a given soil will
have a high water table within certain depths in most years, but they cannot predict
that a high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and
6

identified each as a specific map unit. Aerial photographs show trees, buildings,
fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
onsite investigation is needed to define and locate the soils and miscellaneous
areas.

Custom Soil Resource Report
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha -Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates
(for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper
bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
Please refer to NOAA Atlas 14 document for more information.
