The proposed use of this property will be for the storage of boats, recreational vehicles, trailers, and automobiles, both covered and uncovered. We will also phase in indoor mini warehouse storage units. 2. This property is currently zoned agricultural but has been abandoned for the last three years due to its inability to produce a crop. We feel it's proximity to development in Adams County makes for an opportunity to create jobs and revenue for Weld County with our proposed use. Creating jobs and revenue is consistent with the economic development goals of Weld County. 3. We feel this location is a good fit for a business of this type as there are several storage and processing facilities close by, many home -based businesses close by, and several oil field services companies close by. 4. The surrounding land use is mostly corporate farming with several accessory businesses. Such as landscape contractors, dog kennel, livestock, and directly across the street is a heavy equipment dismantler. Within 1 mile of the property there are three oil field service facilities including a tank Storage lot, water processing facility, and small family farms. 5. Our primary operation will be daylight hours with some limited after hours drop off and pick up with the 24/7 key access. All lighting at the facility will be motion activated LED down lighting. 6. we will have two full-time employees and two part time employees after the construction process is completed. We may need additional staff in the summer for landscape maintenance. 7. We will have one security person during the night shift the rest will all be dayshift. 8. We have estimated that aside from the two full-time employees and two part time employees we will have roughly 10 customers using this site for short periods each day depending on the day of the week and time of the year. 9. Not applicable 10. Please see the attached plans and drainage report. 11. We will have 10 compatible. With both phases at of various lengths. 12. Landscaping now dirt. Our plan has storage space in the center surrounded by 6 foot high parking spaces by the office five of which will be ADA full capacity there will be 1000 Storage parking spaces is a variety of weeds, Thistles, cheat grass, and bare fence on a 2-3 foot high berm with Bushes shrubs trees and semi irrigated dryland grass. Some areas will have rock and mulch. 13. The fencing area along Road 17 will be either wood pickets 6 feet tall or metal fence panels engineered to look like wood pickets. Fence will have Block or Stone posts roughly every 50 to 100 feet Entry area will be stonewalls 8 foot high and wrought iron entry gate Other areas may have chain -link fence with top wire. 14. All outdoor storage area will be screened with a combination of landscaping trees low growing bushes the 10 to 12 foot high range. As well as blackout strips in the chain -link fence where wood fences not used. 15. Not applicable 16. We are providing fire protection for this site in combination with Mountain View fire protection district. We are constructing a water storage facility fire pump and fire hydrant for use by Mountain View for the purpose of the entire area, not just our site. 17. First year we will gravel the parking lot with compacted recycled asphalt construct fence and landscape the road 6 side as well as the road 17 side. The second year we plan to construct the first set of buildings on the north side to provide covered parking. This row of buildings will have solar panels on the roof's making our project energy neutral or a net energy provider. We will build more covered parking Spaces as we have a need for them the beginning of our third season we plan to open phase 2 on the west portion of the property. Phase 2 landscaping will include all of the area on the south side and west side of our parking lot. Environmental health questions. 1. We will use bottled water for the employees as was discussed in the initial minute. We do intend to put a residence on the property eventually it will be serviced by a residential water well. 2. We would like to propose a new septic system for the residential property. We are also setting an area aside for a septic system in the event we decide to install an RV dump station. If we do an RV dump station in the future we will apply for a separate permit. 3. Storage items will be limited to recreational vehicles, boats, automobiles, and trailers. 4. We will not store chemicals, petroleum, or waste products on the site. 5. We will not store fuel on the site other than that which is contained in the storage vehicles. 6. We will not be washing vehicles or equipment on the site. 7. Not applicable 8. Not applicable 9. Not applicable 10.

GENERAL LOCATION AND DESCRIPTION A. Location The proposed project is located within part of Section 20, Township 1 North, Range 67 West of the Sixth Principal Meridian. Specifically, the site is located in Weld County, borders the northwest side of the intersection of county road 6 and county road 17. 6. Description of Property This proposed project site is 58.70 acres. The site is currently being used as farmland. The stormwater drains to the south east to roadside ditches that run along county road 6 and county road 17. The surface condition of the site is currently farmland and based on the NRCS soil survey the soil present on the site is classified as hydrologic group C for 81% of the site and hydrologic group B for 19% of the site (see Appendix D.5). Changes to the site grading are proposed to ensure proper drainage around the site, and include the construction of two detention ponds on the site. II. DRAINAGE BASIN AND SUB -BASINS A. Existing Basin Description From our research our property is not included in any existing major drainage plan for the area and therefore we have designed the proposed property to meet county's drainage requirements. The existing site currently consists of 58.70 acres of farmland which sheet flows to the south east toward roadside ditches along county road 6 and county road 17. Based on the FEMA FIRM panel 08123C2100E dated January 20, 2016 the site is designated as flood zone X, meaning the area has been determined to be outside the 0.2% annual chance floodplain. There is no floodplain modification for this site. Since there has been no known history of flooding in the area and the impacts of the development of the site do not contribute to flooding concerns downstream of the property, it is anticipated that development of North Star RV and Mini Storage, in accordance with the enclosed drainage plans, will not adversely impact downstream infrastructure. It should also be noted that runoff from the property to the north currently drains onto our site, however a berm will be built to route the flow around our site. Table 1: Existing Runoff Values Basin Area (AC) O100 (cfs) EX -1 58.70 35.73 B. Proposed Basin Description Historically the site drains to the south east to roadside ditches along county road 6 and county road 17. The runoff sheet flows offsite as there is currently no storm system in place to capture and convey runoff from on site. Due to the proposed changes in site grading, the existing basins were subdivided into smaller 1 OLSSON ASSOCIATES basins. These basins have been named Basin 1 and Basin 2 (see Appendix D.3 for Post - Developed Drainage Plan). Basin 1 is located on the eastern side of the site along county road 17. This basin drains into detention pond 1 by sheet flow. The pond will drain to the outlet structure at DP1, before being released into the road side ditch along county road 6. Basin 2 is located on the western side of the site. This basin drains into detention pond 2 by sheet flow. This pond will drain to the outlet structure at DP2, before being released into the road side ditch along county road 6. Table 2: Design Point Flows Design Point Basin Q100 (cfs) 1 1 7.80 2 2 7.90 III. DRAINAGE DESIGN CRITERIA A. Regulations The design of the proposed drainage system was completed in accordance with the Urban Storm Drainage Design and Technical Criteria Manual. Development Criteria Reference and Constraints From our research our property is not included in any existing major drainage plan for the area and therefore we have designed the proposed property to meet county drainage requirements. The layout for the development will undergo changes as we will be striping the farmland and constructing an office building, workshop building, storage buildings, landscaping, and detention ponds. It is anticipated that the runoff from the developed land will be conveyed to the where stormwater will pass through outlet structures that limit the release rates of the design storms. Although the layout will be changing, the drainage patterns will not be altered that much. Runoff will still flow to the south east but in the developed condition will be captured before discharging to the roadside ditch along county road 6 and conveyed to the detention ponds. C. Hydrological Criteria According to Weld County, Colorado Urban Drainage Criteria shall be used when designing detention ponds. Colorado Urban Drainage requires that all detention ponds are sized to accommodate flows from the Water Quality Capture Volume, minor storm events, the 100-yr major storm event, and provide 1 ft of freeboard above the 100 -year water surface elevation. J. Hydraulic Criterk. The storm water detention pond was designed to capture and convey the minor event and major event while also providing storage for water quality purposes. The discharge and empirical equations used to size and design the detention pond were determined using the UD-Detention 2 OLSSON A SSC1C I ATES spreadsheet provided by Urban Drainage. In general, stormwater quality will be mitigated on -site during construction with the use of silt fencing, vehicle tracking devices, inlet / outlet protection devices, and other best management practices as needed. IV. )RAINAGE FACILITY DESIGN A. General Concept 1. Detained Area Basin 1 and Basin 2 are developed and therefore runoff must be routed to detention ponds to mitigate the developed runoff. From the detention pond the discharge will be released to an existing roadside ditch along county road 6. 2. Allowable and Modeled Release Rates Detention was sized using the UD-Dentention spreadsheet provided by Colorado Urban Drainage. Urban Drainage allows stormwater to be released at predefined rates as displayed in Table 3. Table 3: UDFCD Allowable Release Rates Pond Storm Event Area (Acres) Allowable Unit Release Rate (cfs/ac) *Allowable Release Rate (cfs) Pond Release Rate (cfs) 1 Major 23.63 .53 12.52 7.80 2 Major 35.07 .53 18.59 7.90 *Allowable Release Rate = Area * Allowable Unit Release Rate From looking at Table 3 it can be seen that pond release rate will be less than the allowable release rate and therefore have met Colorado Urban Drainage Requirements. 3. Specific Details 1. Detention Ponds To mitigate flows from the developed areas detention ponds will be utilized. Detention pond 1 is located in the south east corner of the site. Detention pond 2 is located at the center of the southern boundary of the site. The detention ponds were sized using the UD-Detention spreadsheet provided by Colorado Urban Drainage and includes outlet structures to reduce flows to the release rates determined in Table 3. A complete breakdown of the pond design can be found in Appendix B.

Downstream Conveyance System Historically, flows left the site as sheet flow, directed to the south east into roadside ditches along county road 6 and county road 17. The developed site will release detained runoff at predetermined rates to the existing roadside ditch along county road 6. `7. Stormwater Quality Control Meas Post -development storm water quality will be controlled by the inclusion of water quality orifices in the proposed detention ponds. Water quality volume calculations and orifice sizing were preformed utilizing the UD-Detention spreadsheet provided by Colorado Urban Drainage. V. CONCLUSIONS A. Cnn,n!97rere with Standards All design for the proposed storm system was done in accordance with Colorado Urban Drainage Criteria Manual. Drainage Loncep, Overall, the design of the structures used to convey the runoff from the proposed development will control major and minor storm events effectively. The proposed stormwater system will capture the runoff from the site and route the storm flows to the detention ponds in order to mitigate the project impacts. The detention ponds will attenuate the developed flows and release them at an allowable rate to the existing roadside ditch along county road 6. No offsite drainage improvements are necessary since it is not anticipated that downstream infrastructure will be adversely impacted.

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.

Date(s) aerial images were photographed: Mar 16, 2012 —Apr 13, 2012 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident. 10 Custom Soil Resource Report Map Unit Legend Weld County, Colorado, Southern Part (CO618) Map Unit Symbol Map Unit Name Acres in AOI Percent of AOI 42 Nunn clay loam, 1 to 3 percent slopes 66.5 81.4% 57 Renohill clay loam, 3 to 9 percent slopes 0.1 0.1% 83 Wiley -Colby complex, 3 to 5 percent slopes 15.1 18.5% Totals for Area of Interest 81.7 100.0% 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 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 11 Custom Soil Resource Report 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 42 —Nunn clay loam, 1 to 3 percent slopes Map Unit Setting National map unit symbol: 2tlpl Elevation: 3,900 to 5,840 feet Mean annual precipitation: 13 to 17 inches Mean annual air temperature: 50 to 54 degrees F Frost -free period: 135 to 160 days Farmland classification: Prime farmland if irrigated Map Unit Composition Nunn and similar soils: 85 percent Minor components: 15 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 Erosion Factors Soil Erosion Factors are soil properties and interpretations used in evaluating the soil for potential erosion. Example soil erosion factors can include K factor for the whole soil or on a rock free basis, T factor, wind erodibility group and wind erodibility index. K Factor, Whole Soil Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments. 18 40 2'2"N 4[Y° 1'42'N 8 104° 54' 55" W 507300 77400 507500 Soil Map may not be valid at this scale. 5730 5074W 507500 Map Scale: 1:4,410 if printed on A landscape (11" x 8.5") sheet.

Upon completion of both phases of this storage facility we have an expected number of roundtrips in the range of 10 to 15 per day based on traffic data from this self storage Association. Vehicle types will typically consist of passenger pickups, recreational vehicles, recreational trailers, boats on trailers, and passenger cars. The intended traffic route will be through the entrance gate located approximately 900 feet north of Weld County Road six on Weld County Road 17. Most vehicle or traffic will come either from East or West on Weld County Road six turn north on County Road 17 travel 900 feet then enter our facility. Exiting traffic will travel south from our facility on County Road 17 then either East or West on Weld County Road six. Our facility will be open to vehicles entering and exiting typically from 6 AM to 10 PM it is rare to see these vehicles come in and out outside of those hours. Most of the traffic to and from this facility will occur in the morning between 7 and 9 AM or in the evening between 5 and 9 PM.
