( See attached plan for height and location of trees and fence.) We plan to add on the east side 8 willow type shrubs - a hardy disease resistant and can withstand extreme weather conditions. Tall and upright growing. Will reach 35' to 45' tall with lateral branches from the ground. Will reach 14' to 20' in first year of growth. Life span is estimated to be 70 years. Will make a great screen, as well as a dust and sound barrier. On the south side we would like to plant an orchard type of screening with a variety of Fruit Trees. We will put in 16 trees that at maturity will reach 10' to 15' tall. ( See attached plan for locations we plan to plant.) We feel that this plan will be an appropriate and pleasing to look at for our storage facility. Thank you, Mike and Tami Kaimon • FOUND RE—BI2 ac.

The parcel address is 32956 River Frontage Road, Silt, Colorado and the Garfield County Parcel No. is 2179-091-00-041. The parcel is five acres in size and the portion within the parcel proposed for development is one acre. The proposed development will construct a 20 foot wide entrance drive, perimeter security fence and, gravel cover to accommodate RV and Boat storage. The site is comprised of flat to gently sloping topography draining to the Colorado River. Existing site drainage patterns do not influence off site areas and the proposed development will not alter these patterns. A slight increase in runoff from storm events will occur with the change of cover associated with the gravel. However, these increases will be mitigated with simple BMPs at the site. Drainage Basins There are no major basins other than the Colorado River influencing the one acre portion of the site proposed for development. The Colorado River is located adjacent to the subject parcel. The area of proposed development is outside of the 100 -year floodplain boundary. The relatively flat topography at the site and in the vicinity does not contribute enough runoff to define drainage paths in the area and most runoff eventually infiltrates into the ground. Hydrology The hydrologic methods for estimating runoff in this study are as outlined in the United States Department of Agriculture Natural Resource Conservation Service publication "Urban Hydrology for Small Watersheds" Technical Release 55 (TR -FF). Peak flows will be rainfall derived due to the elevation of the site. Therefore, the storm drainage system will be more than adequate to handle spring snowmelt runoff, as it typically has much lower peaks, even though of longer duration. Pre and post development conditions were considered. Precipitation amounts were gathered from NOAA Atlas 14, Volume 8, Version 2 and are included as Appendix A. Runoff calculations were performed using WinTR-55 Versions 1.0010 and are included in Appendix B. The hydrologic soil characteristics were based on information gathered from the USDA NRCS Web Soil Survey website. The soil report indicated soils at the site to be of Hydrologic Soil Group was "A". The soil report is attached as Appendix C. Runoff curve numbers and time of concentration for the pre and post development conditions were developed in accordance with TR -55 methodology. A summary of peak pre and post runoff rates is provided as Table 1. ENS411.1.4 4t500411.% z:\2017 jobs \17616 kalmon\kalmon_drainage.doc 1 Kalmon RV Park and Boat Storage Facility Increase In Runoff Table 1 Summary of Peak Flows (All values presented in cfs) 1 -yr 2 -yr 5-ry 10 -yr 25 -yr 50 -yr 100 -yr 0.09 0.19 0.30 0.36 0.43 The runoff estimates presented in Table 1 suggest no increase, or negligible increase associated with 1 -yr to 5 -yr 24-hour storms. Larger storms will result in larger increases. However, the increase in runoff from even the 100 -year storm estimated to be 0.43 cfs can be mitigated with a basic berm/ditch surrounding the perimeter of the proposed development. Drainage Plan Detention is not proposed for this development because the site location and drainage patterns do not pose a risk to on site or offsite features. In addition, the low, diffuse flows combined with relatively flat topography would make routing of flow to detention areas difficult and the construction of channels and ponds would disturb more area and cause more erosion than warranted by any benefit gained. The proposed drainage plan is attached. Notable features include an 18 -inch diameter, 36 foot long culvert and perimeter drainage channel, both sized to accommodate the increase in runoff estimated to occur as a result of the proposed development. The installation of gravel is an appropriate BMP for erosion control and will also promote more natural infiltration during precipitation events as opposed to other hardscape alternatives. 7' s..«..I...o 411.1, 14 z:\2017 jobs\1 7616 kalmon\kalmon_drainage.doc 2 Z:\2017 Jobs \17616 Kalmon\Kalmon_Vicinity.mxd Legend [II Kalmon Parcel nGRNOE q� • r77- 1,000 2,000'• 4,000;e Feet? 1 inch = 2,000 feet 5397r-._ /*-• o, TCF SAN 1• 2Q • 5°. y }mr�.• + - c.. l'?,;:.) s7C5:pyLilh2'O 2013' National Geogi-aphie�Society..i=cube Vicinity Map DATE: DRAWN BY Nov. 1, 2017 JAW CHKD BY: TPB APPD BY: AWZ CLIENT: KALMON ZANCANELLA AND ASSOCIATES, INC.

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/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.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www. nres.usda.gov/wps/portal/nres/detail/soils/contactus/? 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 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. 7 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.

As a result, some minor shifting of map unit boundaries may be evident. Custom Soil Resource Report Map Unit Legend 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.

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, 12 Custom Soil Resource Report 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. 13 Custom Soil Resource Report Rifle Area, Colorado, Parts of Garfield and Mesa Counties 40—Kim loam, 3 to 6 percent slopes Map Unit Setting National map unit symbol: jny7 Elevation: 5,000 to 6,000 feet Farmland classification: Prime farmland if irrigated Map Unit Composition Kim and similar soils: 85 percent Estimates are based on observations, descriptions, and transects of the mapunit.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 17 Custom Soil Resource Report Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. 18 39° 32' 36" N 39° 32' 31" N Custom Soil Resource Report Map—Hydrologic Soil Group s F8; 271010 271110 271150 N`X B[M l..rm l cMYY(Y(l� I I rrji k5 I I I I 1 271010 271030 271010 271070 271080 Meters 0 15 30 60 90 Feet 0 50 100 200 3W Map projedion: Web Mercator Comer coordinates: WGS84 Edge tics: UTM Zone 13N WGS84 Map Scale: 1:1,090 if printed on A landscape (11" x 8.5") sheet. 19 271110 271153 271170 271190 39° 32' 31" N 271210 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest (AOI) Area of Interest (AOI) Soils Soil Rating Polygons A ND 0 B 0 B/D 0 C 0 C/D 0 D Q Not rated or not available Soil Rating Lines A . r A/D •— ▪ B B/D • c <„r C/D ••••r . • Not rated or not available Soil Rating Points • A O A/D ■ B ▪ B/D o C ® C/D • D ▪ Not rated or not available Water Features Streams and Canals Transportation 4--14 Rails ,.fir Interstate Highways US Routes Major Roads Local Roads Background Aerial Photography 20 The soil surveys that comprise your AOI were mapped at 1:24,000. Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: 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.
