Dear Ms. Balzano:: We are providing this Drainage Narrative for your review and approval for exception from stormwater detention at 2 770 E. 18th Street, Weld County under the USR 17-0044 application. The USR application has been requested due to portion of the property being used for "commercial purposes" - a staging, storage and parking area utilized for supporting local oil and gas well operations. The Weld County Code (Storm Drainage Policy) Section 23-12-30, F.l.a.10. lists an exception to the drainage policy requiring detention in non -urbanizing areas when the total project stormwater runoff is less than 10 cfs for the 1 -hour, 100 -year storm event. In the case of the property at 2770 E. 18th Street, the 100-yr. developed peak runoff rate has been calculated to be 7.43 cfs. Site Design Criteria The project site is located near the center of a 5.042 acre parcel within the southwest / of Section 11, Township 5 North, Range 65 West, of the 6th Principal Meridian, Weld County, Colorado. The property is zoned Agricultural. Surrounding properties are also agricultural. Existing ground cover is native grass except for gravel roads and parking areas near the existing farm buildings. The proposed "commercial use area" of the property has been cleared and covered with packed gravel as a surface for equipment parking and storage. There is an existing tailwater irrigation ditch that crosses the south end of the property. Access off of the paved asphalt roadway of E. 18th Street is provided by a gravel road that extends south down the west side of the property. The "Soil Survey of Weld County Area, Colorado, Southern Part" prepared by the U.S. Department of Agriculture, Soil Conservation Service, indicates that the surface soils on the site consists mainly of Aquolls and Aquents, gravelly substratum. This soil type is classified in Hydrologic Soil Group D. According to the FEMA Flood Insurance Rate Map (FIRM) Community Panel No. 08123O 1542E dated January 2016, the site is located in Zone X a designated 500 -year floodplain, but not a designated 100 - year floodplain or floodway. There are no know master drainage plans or previous drainage reports for this property or the surrounding area. The property is very flat with less than a foot of slope from west to east. Despite the lack of grade across the property, there are typically no drainage problems encountered by the owner. Rainfall on the property tends to simply soaks into the ground. The general drainage pattern of the property during a major storm Civil, Transportation, & Water Resources Engineering Land Surveying a Geomatics al Mapping www. drexelbarrefr, corn Drainage Narrative, 2770 E. 18th Road 2 December 18, 2017 1 1 S b i • • . • event would have surface runoff traveling across the site in a west to east direction. That is also the typical drainage pattern for the surrounding area south of E. 18th Street; such that runoff from the property to the west would contribute offsite flow across the site and stonnwater would then pass onto the neighboring undeveloped property to the east. For the larger general area, drainage travels eastward where it is intercepted by the Patterson Ditch which empties furthereast into the South Platte River. Drainage Design Criteria Storm design and calculations were based on Weld County Storm Drainage Criteria and the current Urban Storm Drainage Criteria Manual (USDCM). The 1 -hour, 100 -year Rainfall Intensity was taken from Table 5-1 of the Weld County Engineering Construction Criteria. Imperviousness Values are based on Table 5-3 of the Veld County Engineering Construction Criteria. Runoff coefficients were determined using Tables 6-4 and 6-5 from the USDCM. Developed runoff was calculated as follows using the Rational Method: Q = C.I. \\Thel e. Q= peak runoff rate in cubic feet per second (cfs) A = area (acres) I — rainfall intensity (inches) c= runoff coefficient A = 5.042 acres (entire property area) I — 2.78 inches (from Table 5-1) 0100= 0.53 (100-yr composite value based on existing ground covering conditions) Q = 0.53 x 2.78 inches x 5.042 acres = 7.43 cfs Additional calculations in determining the 100 -year runoffcoefficient and other supporting documents are attached and included with this narrative. :\21130-00GRCV\Repor�ts\Drainage\DRAINAGE LETTER #2 .Docx Drainage Narrative, 2 770 F. 18th Road 3 December 18, 2017 Conclusion Based on the following items we request a waiver from providing detention for the USIA application... 1. The historic drainage patterns will not be changed or channelized based on the proposed site use and improvements. The exception for stormwater detention on the property is based on Weld County Code (Storm Drainage Policy) Section 23-12-30, F..1.a.10. The 100 -year runoff rate for the project area (7.43 cfs)is less than allowed (10 cfs). 3. The exception tostormwater detention will not jeopardize the public health, safety, and welfare of public and private property. The neighboring property area which is immediately adjacent to the "commercial" portion of the 2770 E. 18th Street property is undeveloped farmland containing no structures or homes. 4. The flat slopes at the site and the water transfer rate of the soil is high,thus allowing much of the stormwater to pool and infiltrate before ever leaving the site, We sincerely appreciate your time and consideration in the review of this project. If you should have any questions, please feel free to contact this office. Respectfully, Cameron W. Knapp, RE.

It was developed by the UDFCD for use in the urban areas around Denver and Boulder. Portions of Southern Weld County fall within the area for which the CUHP parameters have been calibrated (see Figures RA -1 through RA -12 at the end of this chapter). The most current version of the CUHP model can be downloaded from the UDFCD website under downloads. The CUHP model is generally used for basins that are larger than 160 acres. The CUHP model is not applicable in non -urban areas that are outside of the Denver metropolitan area.

From I-25 and Tri-Town Study, Volume 2, Chapter 2, page 20 5.4.3 Larger Basin Rainfall Methods As noted above, the Rational Method should not be used to determine runoff for basins larger than 160 acres. In areas located in the southwest portion of Weld County and where areas are larger than 160 acres that have drainage characteristics similar to an urban area, the Colorado Urban Hydrograph Procedure (CUHP) is an acceptable model for determining runoff amounts. The CUHP model can be used for basins from 0 to 3,000 acres. The parameter adjustments provided in the runoff chapter of the UDFCD Manual (Volume 1) should be used when dealing with basins that are larger than 160 acres. The CUHP model is not applicable in non -urban areas, including those areas in Weld County that are outside of the Denver metropolitan area. The U.S. Army Corps of Engineers (USACE) HEC-HMS model is more applicable for mixed suburban -agricultural areas. The HEC-HMS model can be used on watersheds and drainage basins larger than 160 acres provided the modeling follows the parameters in the HEC- HMS User's Manual, the HEC-HMS Technical Reference Manual, and the HEC-HMS Application's Guide.

The values for various catchment imperviousness and storm return periods are presented graphically in Figures 6-1 through 6-3, and are tabulated in Table 6-5. These coefficients were developed for the Denver region to work in conjunction with the time of concentration recommendations in Section 2.4. Use of these coefficients and this procedure outside of the semi -arid climate found in the Denver region may not be valid. The UD-Rational Excel workbook performs all the needed calculations to find the runoff coefficient given the soil type and imperviousness and the reader may want to take advantage of this macro -enabled Excel workbook that is available for download from the UDFCD' s website wvw.udfcd.org.

Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSC: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.

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: Jul 17, 2015 —Sep 22, 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. 7 Custom Soil Resource Report Map Unit Legend Map Unit Symbol Map Unit Name Acres in AOI Percent of AOI 3 Aquolls and Aquents, gravelly substratum 6.7 100.0% Totals for Area of Interest 6.7 100.0% 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 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. 8 Custom Soil Resource Report An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 9 Custom Soil Resource Report Weld County, Colorado, Southern Part 3-Aquolls and Aquents, gravelly substratum Map Unit Setting National map unit symbol: 3627 Elevation: 4,000 to 7,200 feet Mean annual precipitation: 12 to 18 inches Mean annual air temperature: 45 to 55 degrees F Frost -free period: 80 to 155 days Farmland classification: Prime farmland if drained and either protected from flooding or not frequently flooded during the growing season Map Unit Composition Aquolls and similar soils: 55 percent Aquents, gravelly substratum, and similar soils: 30 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the rnapunit.

This letter is to inform you of a neighborhood meeting. I recently learned that storing more than one commercial vehicle, or commercial materials is a code violation, of which for the past five months! have been doing. To correct this violation I have to apply for a one time Use by Special Review permit (USR) which requires me to hold this meeting. The idea behind the storage is to give the company running the new natural gas lines in Greeley a place to store their equipment and material outside the city streets of Greeley, no business is conducted on site and no signage will be posted for the business. If the permit goes through there will be no changes from what has been happening for the last 5 months. It is NOT REQUIRED you attend but if you have any questions,. comments or concerns feel free to attend so we can address issues and answer questions. TIME: THURSDAY JULY 20 @ 5:00 PM PLACE: 615 11T" STREET GREELEY, CO (BHEIND THE COLORADO MODEL RAILROAD MUSEUM) THANK YOU, KYLE KEMPEMA Neighborhood meeting sign in sheet NAME ADDRESS PHONE ityLk 63 wag._ _. kie.iin altin.4 n pi, /Ern leocc i fr.- 111: / it -a -if ci--o t2k- aln‘k_e VIS\ --il•ct1/4 7. , lee v 252 - iiiy 3z,3 Tnee3� n� � 5c1-eriui ed fit 1-6-te5 tau z.

We strongly encourage you to discuss your access with public works prior to laying out your site plan to ensure the approved accesses are compatible with your layout. For new accesses and/or change of use of an existing access, the fee and photos are required (photo looking left and right along roadway from the access point and looking in to and out of the access point). These photos are used to evaluate the safety of the access location. Access permit instructions and application can be found at https://www.weldgov.com/departments/public works/permits/. Chapter 6, Sections 6.3, 6.4 and 6.5 of the Weld County Engineering and Construction Criteria offer access design guidance, which can be accessed at: https://www.weldgov.com/departments/public works/engineering/. Appendix 12-A of the county code can also be referenced. Existing access points with change of use or new access points may or may not be granted. Questions pertaining to access permits or access design shall be directed to the Public Works Department. Application Fee: temporary $75, single residential $75, small commercial $75, industrial $150, field $0, large commercial $150, subdivision $150. This can be accessed at: https://www.weldgov.com/departments/public works/engineering/. For shared accesses, Public Works strongly recommends the property owner establish an access road maintenance agreement so future owners of the properties will be aware of their requirements for shared maintenance of the access road. This is not a requirement for the recorded exemption but is recommended to avoid property owner conflicts in the future. Per Chapter 12, Appendix 12A.4.1 of the Weld County Code, an access approach that is gated shall be designed so that the longest vehicle (including trailers) using the access can completely clear the traveled way when the gate is closed. In no event, shall the distance from the gate to the edge of the traveled surface be less than 35 feet. Per Chapter 12, Appendix 12A.10.1, traffic volumes to the proposed facility may require the installation of a tracking control device and/or a minimum of four inches of compacted recycled asphalt or aggregate road base. Tracking control is required to prevent tracking from the site onto public roadways. Minimal standards are listed below. Temporary Tracking Control shall be used during construction unless permanent tracking control is installed ahead of construction activities. 20 to 50 passenger vehicle round trips/day or less than 4 truck round trips/day: • Access onto gravel roads includes 50 feet of road base or recycled asphalt. • Access onto paved roads includes 100 feet of road base or recycled asphalt. *Note: Recycled concrete is not allowed in County right-of-way **Tracking control devices can be double cattle guards or rip rap (6" washed rock) ***Tracking control for unmaintained public right-of-way is required just prior to entering publicly maintained roadways. A variance request for alternatives to the above tracking control can be submitted to Public Works for review and consideration. As part of the development review process, all new commercial or residential developments will be required to submit a TIS that is prepared, stamped, and signed by a professional engineer licensed in the State of Colorado, unless the TIS is waived by Public Works. Traffic Narrative 1. Describe how many roundtripslday are expected for each vehicle type: Passenger Cars/Pickups, Tandem Trucks, Semi-Truck/Trailer/RV (Roundtrip = 1 trip in and 1 trip out of site) 2.

This area IS within a Non -Urbanizing Drainage Area: Non -Urbanizing Drainage Areas generally require detention of runoff from the 1 -hour, 100 -year, storm falling on the developed site and release of the detained water at the historic runoff rate of the 1 -hour, 10 -year storm falling on the undeveloped site. Detention pond summarized in a drainage report is required unless the project falls under an exception to stormwater detention requirements per code section 23-12-30 F.1. To avoid holding up case processing, a minimum of either a preliminary drainage report or a drainage narrative with exception as shown below must be submitted with 7 -day case submittal information. Detention Pond Requirements: 1. A Drainage Report and Detention Pond Design shall be completed by a Colorado Licensed Professional Engineer and adhere to the drainage related sections of the Weld County Code. The Drainage Report must include a Certification of Compliance, stamped and signed by the PE, which can be found on the engineering website. A general Drainage Report Guidance Checklist is available on the engineering website. A Preliminary Drainage Report or a qualifying exception and Drainage Narrative shown below must be submitted for review at the time of the application. OR 2. Drainage Narrative requirements with exception from detention pond. The Drainage Narrative must describe at a minimum: i. Which exception is being applied for and include supporting documentation ii. Where the water originates if it flows onto the property from an offsite source iii. Where it flows to as it leaves the property iv. The direction of flow across the property v. If there have been previous drainage problems with the property DRAINAGE CODE REQUIREMENTS (informational only): Section 23-12-30. Drainage Policy. F. Exceptions. 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. 1. Use by Right or Accessory Use in the A (Agricultural) Zone District. 2. Zoning Permits in the A (Agricultural) Zone District. 3. A second dwelling permit in the A (Agricultural) Zone District. 4. Towers including, but not limited to, cell, wind, and telecommunication towers. 5. Pipelines or transmission lines. 6. Gravel pits if the stormwater drains into the gravel pit. 7. Residential developments where all the following conditions exist: i. Nine (9) lots or fewer. ii. The average lot size is equal to, or greater than, three (3) acres per lot. iii. Downstream roadway criteria are not exceeded. iv. The total post -development imperviousness for the rural residential development does not exceed ten percent (10%), assuming that all internal roads and driveways are paved, or will eventually be paved. 8. Development of sites where the change of use does not increase the imperviousness of the site. 9. URBANIZING areas where the total project stormwater runoff of less than, or equal to, 5 cubic feet per second (cfs) for the 1 -hour, 100 -year, storm event. 10. NON -URBANIZING areas where the total project stormwater runoff of less than, or equal to, 10 cfs for the 1 -hour, 100 -year, storm event. 11. Parcels with total area less than, or equal to, a 1.0 gross acre. 12.
