A, B, C, & E of the Weld County Code) 1. Explain the proposed use and business name. Laura and Samuel Gavito doing business as Gavito Trucking Inc. (Gavito Trucking), are requesting a Use by Special Review (USR) permit for an oil and gas support and service business with accessory agricultural service establishment uses in the agricultural zone district, more specifically a trucking company principally engaged in serving the oil and gas industry, as allowed by Section 23-3-40.V of the Weld County Code. The 7.15 -acre subject property is located in Part of the Southwest Quarter of Section 01, Township 02 North, Range 67 West of the 6th P.M., being Lot A of Recorded Exemption RE -4146. The subject property contains a 2,900 -square foot residence, 1,200 -square foot agricultural exempt livestock shelter, and 3,500 -square foot agricultural exempt hay shed. The existing structures will continue to be used for the primary residential uses and are not proposed to be used with the commercial operation. Access to the property is via Weld County Road (WCR) 23. The access location is shown on the USR plat included with this request. The on -site operation will primarily be for the parking of trucks. No on -site operations are proposed except for the pickup and drop off of trucks. The majority of Gavito Trucking's operations will occur off -site at various oil and gas locations around the county. Parking of vehicles will occur along the north and west side of the hay storage building. Vehicles that may be on -site include up to 9 semi -trucks and trailers, and 9 employee passenger vehicles. The majority of the equipment, including the trailers, is staged at the construction site, and returned to the facility as needed. Parking on site will occur 24 hours a day, seven days a week, when employees are not taking the vehicles off -site for business. The primary hours of operation are 5:00 A.M. to 7:00 P.M., Monday through Friday. 2. Explain the need for the proposed use. Gavito Trucking is a northern Colorado based business specializing in delivering equipment and materials to oil and gas sites around the county. They also transport materials and products for custom farming operations. Weld County recognizes mineral resources as vital to the state's economy. Oil and gas support service businesses are an important part of the mineral resource industry. ENGINEERING, PLANNING, CONSULTING & REAL ESTATE HQ & Mailing: 3050 67th Avenue, Suite 200, Greeley, CO 80634 1970-535-9318 office 1970-535-9854 fax Idaho: 213 Canyon Crest Drive, Suite 100, Twin Falls, ID 83301 1208-595-5301 www.agpros.com Page 2 of 9 3. Describe the current and previous use of the land. The site is currently used for residential purposes as the owners live on site. The small-scale trucking operation has been operating as described in this application, on site since they purchased the property in 2013. No additional site improvements are proposed. 4. Describe the proximity of the proposed use to residences. The closest residences to the proposed USR boundary are located approximately 471 feet north and 480 feet west. There are two other residences located approximately 500 feet southwest and 615 -feet southeast of the subject area. The southern parcel has several access points on WCR 23 that are not shared. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. The subject property and the majority of the surrounding properties are in the Agricultural (A) Zone District. In addition to rural residential, rangeland, and oil and gas activities typically found in the A Zone, there are several USRs in the surrounding area. USRs in the vicinity of this site include several mining operations, pipelines, directional drilling, dairy, and outdoor storage. The proposed oil and gas trucking operation is compatible with the surrounding land uses. There are multiple oil and gas facilities in the vicinity and the proposed use directly supports the oil and gas industry. Company and employee generated traffic is expected to be very minimal with current operations having up to 4 trips accessing the property daily and with proposed operations, up to 36 trips accessing the subject property each day. Other traffic to the site will be associated with the residential uses associated with the principal dwelling. The operation is not expected to produce nuisance noise levels or odors. 6. Describe the hours and days of operation (i.e. Monday through Friday 8:00 a.m. to 5:00 p.m.). Parking and equipment storage will occur 24 hours a day, 7 days a week, when employees are not taking the vehicles and equipment off -site for business. The on -site operations will primarily occur between 5:00 a.m. to 7:00 p.m., Monday - Friday. Occasional operations outside of the primary hours may be required due to the oil and gas industry service needs. 7. Describe the number of employees including full-time, part-time and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. It is expected that the operation will have 3-9 full-time employees as the operation currently has 3 full-time employees. Page 3 of 9 Off -Site Employees: There will be one shift per day, from 5:00 a.m. to 7:00 p.m. With current operations, on average less than two employees are on site daily; they will pick up their work trucks and then leave for off -site operations. The expanded operations may result in up to 9 truck drivers entering the site daily. S. Describe the maximum number of users, patrons, members, buyers, or other visitors that the site will accommodate at any one time. Currently less than 2 employees enter the site daily, but up to 9 employees may access the site per day. Due to the type of business, customers and deliveries are not expected to come to the property. 9. List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock confinement operations, kennels, etc.) N/A. 10. List the types and number of operating and processing equipment. 9 — Semi -trucks and trailers 2-9 — Employee vehicles 11. List the types, number, and uses of the existing and proposed structures. The subject property contains a 2,900 -square foot residence, 1,200 -square foot agricultural exempt livestock shelter, and 3,500 -square foot agricultural exempt hay shed. The existing structures will continue to be used for the primary residential uses and are not proposed to be used with the commercial operation. There are no proposed structures for the trucking operation. 12. Describe the size of any stockpile, storage or waste areas. No storage or stockpiling of waste is proposed on site at this time. There will be minimal outdoor storage associated with this use. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. The proposed use is not anticipated to produce nuisance debris, junk, or other wastes. A waste service provider will be used to dispose of excess materials and trash. 14. Include a time -table showing the periods of time required for the construction of the operation. The facility is existing; additional construction is not anticipated with this USR. Page 4 of 9 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). The site is an existing rural residential site. There is approximately 38,000 sf of gravel drive that is used by the on -site residence, trucking operation, and easement road for off -site oil and gas operations and approximately 244,000 sf of grass, landscaping, and agricultural field. A Drainage Narrative has been prepared and is included with this request. 16. How many parking spaces are proposed? How many handicapped -accessible parking spaces are proposed? 9 semi -truck parking spaces are proposed, and an additional 4 standard spaces are provided. Parking is proposed to be circulated so when an employee picks up a commercial vehicle, they will park their personal vehicle in that space. These are shown on the USR site plan. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. The property has pipe fencing along the WCR 23 frontage and around the remaining perimeter. Existing trees on adjacent properties create a natural buffer to the parking area. No additional fencing is proposed as minimal outdoor storage for the on -site operations is expected and the site topography indicates no concerns with this. 18. Describe the existing and proposed landscaping for the site. A majority of the site contains a hay field and grass associated with the residence. No additional landscaping is proposed. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. 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. A USR is a vested property right that remains with the land until such time as the use is changed or the USR is formally vacated. 20. Describe the proposed fire protection measures. Fire protection for the site is provided by the Fort Lupton Fire Protection District. A fire extinguisher will be kept on -site. All commercial vehicles are equipped with a fire extinguisher in conformance with the Federal Motor Carrier Safety Administration regulations. It is anticipated that no additional fire protection measures will be necessary. Page 5 of 9 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. The approval of this request would be consistent with Section 22-2-10 B. of the Weld County Code, which states "One of the basic principles upon which the United States was founded is the right of citizens to own and utilize property so long as that use complies with local regulations and does not interfere with or infringe upon the rights of others." The proposed use will not inhibit agricultural production or operations and is harmonious with the surrounding land uses. 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 III of Chapter 23 of the Weld County Code.) The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and 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 supports the natural resource extraction and energy development occurring in Weld County. In addition, Article III of Chapter 23 of the Weld County Code lists oil and gas support and service businesses as a use allowed by special review outside of subdivisions and historic townsites. 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 within the Intergovernmental Agreement (IGA) for Fort Lupton, Firestone, and Platteville. Per the Weld County Comprehensive Plan Map, the site is within an area recommended for annexation. Notice of Inquiry forms were submitted to the three municipalities, and they were not interested in requiring annexation of this development. The site is approximately 1.15 miles from the Weld County Opportunity Zone. As no subdivisions or zone changes are proposed, the development classifications and proximity to the Weld County Opportunity Zone 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 expected to have minimal impact on the health, safety, and welfare of the inhabitants of the neighborhood and the County. Business -related traffic will be minimal, and operations will occur primarily off -site at specific job locations. This is an existing business operation that has operated on site with no issues from the neighbors. A Nuisance and Waste Management Plan has been developed and is included with this request. Page 6 of 9 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. There are no existing irrigation ditches or canals crossing this site. The improvements on -site are existing, and no new improvements are proposed on the undeveloped areas of the property. There is a small hay field on site that is not of the size or scale to be considered a commercial farming operation. This field will not be taken out of production as a result of this operation. 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, or Historic Townsites Overlay Districts. The subject property is not located in a Special Flood Hazard Area, but the floodplain does run along the very north property boundary. 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. No state or federal permits are anticipated with this USR. The loading and unloading of materials will occur off -site at each job location. Should state or federal permits be determined to be required, it is requested to be a Condition of Approval to the USR. Environmental Health Questions: (Chapters 14, 23, and 30 of the Weld County Code) 1. Discuss the existing and proposed potable water source. If utilizing a drinking water well, include either the well permit or well permit application that was submitted to the State Division of Water Resources. If utilizing a public water tap, include a letter from the Water District, a tap or meter number, or a copy of the water bill. There is a Central Weld County Water District water tap served under account no. 001968-02 that currently supplies water service to the property. A copy of the water bill is included with this application. 2. Discuss the existing and proposed sewage disposal system. What type of sewage disposal system is on the property? If utilizing an existing on -site wastewater treatment system provide the on -site wastewater treatment permit number. (If there is no on -site wastewater treatment system permit due to the age of the existing on -site wastewater treatment system, apply for an on -site wastewater treatment system permit through the Department of Public Hearing and Environment prior to submitting this application.) If a new on -site wastewater treatment system will be installed, please state "a new on -site Page 7 of 9 wastewater treatment system is proposed." (Only propose portable toilets if the use is consistent with the Department of Public Health and Environment's portable toilet policy.) There is an existing septic system, permit no. SP-O6OO15O, that provides sewage disposal to the property. No change to the existing septic system is proposed. Portable toilets will be provided for off -site employees as they will be on -site for less than 2 consecutive hours per day. The operator will utilize an appropriate sanitary services provider to manage the toilets and remove and dispose of contents as needed in accordance with applicable requirements. 3. If storage or warehousing is proposed, what type of items will be stored? The site is not proposed to be used for long-term storage or warehousing. 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. The site is not proposed to be used for the storage and/or stockpiling of wastes, chemicals, or fuel. 5. If there will be fuel storage on site, indicate the gallons and the secondary containment. State the number of tanks and gallons per tank. There is no fuel storage proposed. 6. If there will be washing or vehicles or equipment on site, indicate how the wash water will be contained. Washing of vehicles or equipment is not proposed. 7. If there are floor drains, indicate how the fluids will be contained. No floor drains are existing or proposed. 8. Indicate if there will be any air emissions (e.g. painting, oil storage, etc.). The trucking operations occur primarily off -site at each job location. The on -site parking is expected to be well below the air pollution emission notice (ADEN) permit thresholds. 9. Provide a design and operations plan if applicable (e.g. composting, landfills, etc.) N/A. 10. Provide a nuisance management plan if applicable (e.g. dairies, feedlots, etc.) Page 8 of 9 N/A. 11. Additional information may be requested depending on type of land use requested. Noted. Public Works Questions: (Section 8-11-40, Appendix 8-Q, and Section 8-14-10 of the Weld County Code) 1. Describe the access location and applicable use types (i.e., agricultural, residential, commercial/industrial, and/or oil and gas) of all existing and proposed accesses to the parcel. Include the approximate distance each access is (or will be if proposed) from an intersecting county road. State that no existing access is present or that no new access is proposed, if applicable. There is an existing agricultural, residential, and oil & gas access located on WCR 23 approximately 995 feet north of WCR 24. A new access permit to change the use to commercial is requested to be a Condition of Approval to the USR. 2. Describe any anticipated change(s) to an existing access, if applicable. No additional access points are proposed. A new access permit for commercial use will be submitted upon USR conditional approval. 3. Describe in detail any existing or proposed access gate including its location. There is no access gate at the entrance of the subject property and access gates are not proposed. 4. Describe the location of all existing accesses on adjacent parcels and on parcels located on the opposite side of the road. Include the approximate distance each access is from an intersecting county road. WCR 23 is a collector road maintained by Weld County. The adjacent parcel to the south has existing residential and agricultural access located approximately 880 feet north of WCR 24. On the west side of WCR 23, the adjacent parcel located north of the subject property has an existing residential and agricultural access approximately 1,330 feet north of WCR 24, and the adjacent parcel directly to the north of the subject property has an existing residential access approximately 1,790 feet north of WCR 24. 5. Describe any difficulties seeing oncoming traffic from an existing access and any anticipated difficulties seeing oncoming traffic from a proposed access. As WCR 23 is a relatively flat and straight roadway in front of the entrance, and there are no significant visual obstructions in the sight triangles, no difficulties seeing oncoming traffic from the existing access are anticipated. Page 9 of 9 6. Describe any horizontal curve (using terms like mid curve, sharp curve, reverse curve, etc.) in the vicinity of an existing or proposed access. WCR 23 is a relatively flat and straight roadway in front of the entry and there are no significant horizontal curves in the vicinity of the existing approved access. 7. Describe the topography (using terms like flat, slight hills, steep hills, etc.) of the road in the vicinity of an existing or proposed access. WCR 23 is a relatively flat and straight roadway in front of the entry.

Valene Lie "='y Cauhorn, RE. AGPROfessionals Brook Delaney, EIT AGPROfessionals AGPROfessionals 3 March 12, 2024 Samuel & Laura Gavito — Drainage Narrative Summary Samuel and Laura Gavito are requesting a Use by Special Review (USR) permit for their project site for an oil and gas support and service business with accessory agricultural service establishment uses in the agricultural zone district, more specifically a trucking company principally engaged in serving the oil and gas industry, as allowed by Section 23-3-40.V of the Weld County Code. The subject property contains a 2,900 -square foot residence, 1,200 -square foot agricultural exempt livestock shelter, and 3,500 -square foot agricultural exempt hay shed. The existing structures will continue to be used for the primary residential uses and are not proposed to be used with the commercial operation. The on -site operation will primarily be for the parking of trucks which will not occur within a building. No on -site operations are proposed except for the pickup and drop off of trucks. The subject property is 7.14 acres. The USR does not change the conditions of the site and, therefore, is exempt from stormwater detention per Article XI, Storm Drainage Criteria, Section 8-11-40 Drainage Policy. I. Exceptions. I. 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 (fitfiows onto the property from an off -site source. 4. Where the water flows as it leaves the property. S. 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: 13) A parcel greater than five (5) gross acres in size is allowed a onetime exception for a new nine thousand (9,000) sq. ft. of 100% impervious area or equivalent imperviousness. (See Appendix 8-Q in the Weld County Engineering and Construction Criteria Manual for impervious value percentages). AGPROfessionals 4 March 12, 2024 Samuel & Laura Gavito — Drainage Narrative Introduction 1. Location The subject property is located at 11192 CR 23, Fort Lupton, CO 80621, more particularly described as being in the Southwest Quarter of Section 01, Township 02 North, Range 67 West of the 6th P.M., being Lot A of Recorded Exemption RE -4146. Access to the property is via Weld County Road (WCR) 23. The properties surrounding the proposed sites are residential properties. A vicinity map is shown in Appendix A. 2. Property Description The site currently contains a 2,900 -square foot residence, 1,200 -square foot agricultural exempt livestock shelter, and 3,500 -square foot agricultural exempt hay shed. The existing structures will continue to be used for the primary residential uses and are not proposed to be used with the commercial operation. The commercial operation will be limited to outdoor parking of vehicles. There are three predominant soil types on site. The soil consists of Altvan loam, 1 to 3 percent slope, Ellicott -Ellicott sandy -skeletal complex, 0 to 3 percent slope, and Ustic Torriorthents, moderately steep. (See USDA-NRCS soil report in Appendix B). There are no major open channels within the proposed property. Historic Drainage 1. Overall Basin Description The site has a generally flat topography with slopes from 0 to 3 percent. A topographic map was downloaded from the United States Geological Survey (USGS) website and is provided in Appendix C. 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 D. The property is located on pane108123C1915F, and a portion of the property is located inside the Zone AE floodplain. Zone AE floodplain is AE flood zones are areas that present a 1% annual chance of flooding. The portion of the parcel that is included in the floodplain does not appear to extend to the parking area. 2. Drainage Patterns Through Property The site is in Weld County. The property is surrounded by agricultural zoned land. A Master Plan for the site area is not currently available. The site is generally flat surface and appears to slope north. AGPROfessionals 5 March 12, 2024 Samuel & Laura Gavito — Drainage Narrative 3. Off -site Drainage Flow Patterns Offsite flows from the north appear to flow north away from the site. Offsite flows from the south appear to flow south away from the site. Offsite flows from the east appear to flow northeast away from the site. Offsite flows from the west flow west away from the site; therefore, an increase in runoff is not expected. 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 Greeley, CO precipitation station, the estimated rainfall from the 100 -year, 1 -hour precipitation is 2.70 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 UDFCD Table 6-3. The overall percentage of imperviousness for the proposed site was determined to be approximately 10 percent (see Percentage of Imperviousness Calculation in Appendix F). Conclusions This drainage narrative is consistent with the Weld County Storm Drainage Criteria and the UDFCD Criteria Manual. An increased risk of damage from storm runoff is not expected since no changes are to be made to the site and it is within a flood plain. As no structures are proposed for this use, the site is, is exempt from stormwater detention per Article XI, Storm Drainage Criteria, Section 8-11-40 Drainage Policy for a parcel greater than five (5) gross acres in size is allowed a onetime exception for a new nine thousand (9,000) sq. ft. building or equivalent imperviousness.

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.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nrcs142p2_053951). 142p2_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 Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

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 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

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. 11 Custom Soil Resource Report 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. 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. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 2 Altvan loam, 1 to 3 percent slopes Map Unit Setting National map unit symbol: 361w Elevation: 4,500 to 4,900 feet Mean annual precipitation: 14 to 16 inches Mean annual air temperature: 46 to 48 degrees F Frost -free period: 130 to 150 days Farmland classification: Prime farmland if irrigated Map Unit Composition Altvan and similar soils: 90 percent Minor components: 10 percent Estimates are based on observations, descriptions, and transects of the mapunit.

It is expected that the operation will have up to 9 full-time employees. The expected work hours will vary based on job type. Parking and equipment storage will occur 24 hours per day, 7 days per week. The primary hours for outgoing and incoming vehicles and equipment will be Monday through Friday, 5:00 A.M. to 7:00 P.M. Other uses in the surrounding area include rural residential, agricultural, several mining operations, directional drilling company, dairy, and outdoor storage. Gavito Trucking Inc. will use the methods described below to minimize potential nuisances and waste produced as a result of the proposed uses. Noise The property owner or operator will attempt to minimize noise generated during operation and maintain compliance with Weld County Noise Requirements. The facility will adhere to the maximum permissible noise levels allowed in the Agricultural Zone District. On -site operations will primarily be the pick-up and drop-off of trucks. Trucks are not expected to be brought back to the facility daily. As on -site operations are limited, no additional sound buffering is proposed. Light No outdoor lighting is existing or proposed for the commercial operation. Should lighting be installed in the future, the lights will be shielded so that light rays will not shine directly onto adjacent properties where such would cause a nuisance or interfere with the use on the adjacent properties. Neither the direct, nor reflected light from any light source will create a traffic hazard to operators of motor vehicles on public or private streets. No colored light will be used which may be confused with, or construed as, traffic control devices.

Gavito Trucking attempts to limit the amount of waste generated from the truck parking. For all on -site operations, trash will be collected in a covered, confined trash dumpster and removed as needed by a trash removal company. There is no sanitary sewer service to, or within four hundred feet of, the subject property. As the employees will generally be on site for less than two hours per day, portable toilets are expected to be adequate for the 9 employees. Dust Abatement The operation is not expected to generate disproportionate amounts of fugitive dust. Lot surfaces are primarily grass, hay, and improved gravel surfaces in roadways, parking, and operations areas. Parking is internal to the site. The subject property is accessed along the west of the parcel from the existing gravel drive located on Weld County Road (WCR) 23 approximately one fifth of a mile north of WCR 24. WCR 23 is a paved collector road maintained by Weld County. Vehicles will not gain significant speed on -site before the access road intersects with WCR 24 due to the distance from the operations area to WCR 23. Watering of surfaces will occur as necessary to suppress dust. AGPRCfessionals DEVELOPERS OF AGRICULTURE Traffic Narrative Prepared for Laura & Samuel Gavito Introduction This Traffic Narrative is prepared for the Gavito Trucking Inc. Use by Special Review request for an oil and gas support and services business in the Agricultural Zone District, more specifically a trucking operation. The subject property is described as Lot A of Recorded Exemption RE -4146 located in Part of the Southwest Quarter of Section 01, Township 02 North, Range 67 West of the 6th P.M., Weld County, Colorado. The approximately 7.15 -acre property is located on Weld County Road (WCR) 23 approximately one fifth of a mile north of WCR 24. The purpose of this narrative is to document projected traffic generation relative to the existing street system. Off -site roadway warrants are not provided with this narrative, nor are existing traffic counts documented. Existing Conditions and Roadway Network The subject property is accessed on the west part of the parcel from the existing gravel drive located on WCR 23 approximately one fifth of a mile north of WCR 24. WCR 23 is a paved two-lane north -south street and is classified as a collector roadway. WCR 24 1/2 is a paved two-lane east -west street and is classified as a collector roadway according to the 2045 Transportation Plan. WCR 24 is paved west from the intersection of WCR 23 and has been annexed by Fort Lupton. WCR 24 turns into a private road east from the intersection of WCR 23, accessing into the adjacent gravel mine. All routes to and from the site will be on WCR 24. Figure 1.

The trucking operation is also existing. The current buildings will continue to be used for residential purposes. The on -site operation will primarily be truck parking. The majority of Gavito Trucking's operations will occur off -site at various oil and gas locations around the county. Vehicles that may be on -site include semi -trucks and trailers and employee passenger vehicles. The vehicles may be stored on the oil and gas sites and returned to the facility as needed. Trip Generation Parking and equipment storage will occur 24 hours per day, 7 days per week. The expected hours for outgoing and incoming vehicles and equipment will be Monday through Friday, 5:00 A.M. to 7:00 P.M. The Peak Hour will be from 6:00 A.M. to 7:00 A.M. in the morning, and in the evening between 6:00 P.M. to 7:00 P.M. On -site operations are existing. Operations include staggering employee truck drivers. It is not expected that all employees will need to pick up or drop off trucks on the same day as they may be on job sites consecutive days in a row and trucks are not returned daily. The traffic numbers provided below are the assumed maximum that the site could see at full build out. The following numbers are broken out into the current operations and proposed max. operations: Current Operations Use Daily Trips AM Peak Hour PM Peak Hour 4 Off -Site Employees (2) 2 = 1 in/1 2 = 1 in/1 out out Total: 4 2 2 Proposed Operations Use Daily Trips AM Peak Hour PM Peak Hour 36 Off -Site Employees (9) 18 = 9 in/9 18 = 9 in/9 out out Total: 36 18 18 Travel Routes The most direct travel routes to/from the subject property are via WCR 23 north to WCR 24.5 then west to WCR 21.5, or via WCR 23 south to either WCR 20 or WCR 18. It is assumed that 5-10% of traffic exiting the site will go north on WCR 23 and that 90-95% of traffic exiting the site will head south on WCR 23. Figure 2 shows expected travel routes. Page 3 of 3 Figure 2. Travel Routes Conclusion Site traffic volumes are not expected to differ much from current volumes. As the peak hour left turning volume is less than 10 vehicles and the peak hour right turning volume is less than 25 vehicles, no roadway improvements are anticipated for the proposed uses.
