Chad TeVelde, RE. AGPROfessionals fessionals 9/1412018 Drainage Narrative Page 3 of 9 AOPROfessienals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros.com Dorrance Proposed Shop Summary The applicant is proposing the addition of a 4,500 square foot shop on approximately 25,000 square feet of the 120.71 -acre parcel. The proposed site is currently an agricultural property. The site is located in a non -urbanizing region with the proposed development having less than 10► cubic feet per second (cfs) for the 100 -year, 1 -hour stormevent. Therefore, it is exempt from stormwater detention per Article XII, Storm Drainage Criteria, Section 23-12-30 Drainage Policy. F. Exceptions. 1. Exceptions to stormwater detention shall not jeopardize the public health, safety, and welfare of public and private property and shall be limited to the following: 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. 10) NON -URBANIZING areas where the total project stormwater runoff of less than, or equal to, 10 efs for the 1 our, 100 -year, storm event. 9/1412018 Drainage Narrative Page 4 of 9 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros.com Dorrance Proposed Shop Introduction 1. Location The proposed site is located in partof the northeast 4 of Section 4, T7N, R67W of the 6th PM. This site is located north of Highway 14 and north of the Town of Severance, CO. The properties surrounding the site are undeveloped, agricultural farm land. The property is bordered along the north side by Weld County Road (WCR) 86 and along the east side by WCR 19. The nearest road to the west is WCR 15 and to the south is WCR 84. A vicinity map is shown in Appendix A. 2. Property Description The applicant is proposing a 4,500 square foot shop on approximately 25,000 square feet of the 120.71 -acre property. The proposed site is currently a non -urbanizing, agricultural property with an existing residence and outbuildings. There are five types of soil: Cascajo gravelly sandy loam (5% to 20% slopes), Haverson loam (1% to 3% slopes), Nunn loam (1% to 3% slopes), Olney fine sandy loam (1% to 3% slopes), and Renohill clay loam (0% to 9% slopes). The majority of the soil is well drained, hydrologic soil group D (see USDA-NRCS Custom Soil Resource Report in Appendix B) . The Pierce Lateral runs through the middle of the property towards the Lariiner County Canal, where stormwater from the site currently discharges. There are no other major open channels within or adjacent to the proposed property. 9/1412018 Drainage Narrative Page 5 of 9 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros.com Dorrance Proposed Shop Historic Drainage 1. Overall Basin Description The site has a relatively flat topography with slopes ranging from approximately zero to nine percent predominately towards the east-northeast. A topographic map was downloaded from the United States Geological Survey (USGS) website and is shown 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 panel 08123O 1185E and is not currently located within a 100 -year floodplain. 2. Drainage Patterns Through Property The site is located in rural Weld County and is surrounded by undeveloped, agricultural land. A Master Plan for the site area is not currently available. The site is mostly east- northeast sloping and has a generally flat topography. Historically, the basin drainage flows towards the Pierce Lateral and into the Larinner County Canal, 3. Off -site Drainage Flow Patterns Offsite flows from the east, north and south should continue to flow east around the site. Offsite flows from the west flow partially towards the northeast and partially towards the Pierce Lateral. Therefore, an increase due to offsite flows is not expected. 9/14/2018 Drainage Narrative Page 6 of 9 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros.com Dorrance Proposed Shop 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 Fort Collins, CO precipitation station, the estimated rainfall from the 100 -year, 1 -hour precipitation is 2.80 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 20 percent (see Percentage of Imperviousness Calculation in Appendix F). Using the 100 -year, 1 -hour design storm and the UDFCD Detention Basin spreadsheet, the peak runoff flowrate was estimated using the Modified FAA method. 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 C). The peak runoff flowrate was determined to be approximately 2.05 cubic feet per second (cfs). 9/14/2018 Drainage Narrative Page 7 of 9 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros.com Dorrance Proposed Shop Conclusions This drainage narrative is consistent with the Weld County Engineering and Construction Guidelines. An increased risk of damage from storm runoff is not expected since the site is located in a non -urbanizing region with the proposed development having less than 10 cfs for the 100 -year, 1 -hour storm event. We recommend that the site is exempt from stormwater detention per Article XII, Storm Drainage Criteria, Section 23-12-30 Drainage Policy. 9/14/2018 Drainage Narrative Page 8 of 9 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros.com Dorrance Proposed Shop List of References Federal Emergency Management Agency.

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.nres.usda.gavlwpsl portal/n reslm ain /so i l sf health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.govllacatorlapp?agency=arcs) or your N RCS State Soil Scientist (http://www. nres.0 sda.gov/wps/portal/nresfd etail/soils/contactu sl? cid=nres142p2_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 N RCS 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.

Warning: Soil Map may not be valid at this scale.. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required. This product is generated from the USDA-NRCS certified data as of the version date(s) listed below. Soil Survey Area: Weld County, Colorado, Southern Part Survey Area Data: Version 16, Oct 10, 2017 Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Mar 20, 2015 —Oct 15, 2016 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident. 10 Custom Soil Resource Report Map Unit Legend Map Unit Symbol Map Unit Name Acres in Aol Percent of Aol 13 Cascajo to 20 gravelly sandy percent slopes loam, 5 0.2 0.1% 26 Haverson slopes loam, 1 to 3 percent 0.4 0.3% 40 Nunn slopes loam, 1 to 3 percent 1.0 0.8% 47 Olney fine sandy percent slopes loam, 1 to 3 4.4 3.2% 56 Renohill clay percent slopes loam, 0 to 3 17.6 12.8% 57 Renohill clay percent slopes loam, 3 to 9 114.0 82.8% Totals for Area of Interest 137.6 100.0% 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 non contrasting, 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 ferent 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 11 Custom Soil Resource Report 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. 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 13 Cascajo gravelly sandy loam, 5 to 20 percent slopes Map Unit Setting National map unit symbol: 361 n Elevation: 4,600 to 5,200 feet Mean annual precipitation: 11 to 13 inches Mean annual air temperature: 52 to 54 degrees F Frost -free period: 120 to 160 days Farmland classification: Not prime farmland Map Unit Composition Cascajo and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

Numbers in parenthesis are PF estimates at rawer 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.
