Very truly yours, Steve Lundvall Ingrid Lun all SITE SPECIFIC DEVELOPMENT PLAN AND USE BY SPECIAL REVIEW (USR) QUESTIONNAIRE 1. Explain,in detail,the proposed use of the property. A. Memorandum (Pre-application Meeting)of December 12,2013 Proposed Use The Background Information from the Memorandum of December 12,2013, states that"the applicants are proposing a truck and equipment business ...". This use has undergone minor changes that have down-graded in intensity. The sole purpose for the current use is the storage for support of industry as described in Part 1.B. below. Thus,there will be no truck cleaning, pressure washing,minor maintenance of rigs and equipment, repairs or welding projects. Additionally,there will not be 2 mobile offices for the proposed use. Applicant would like approval for one(1)temporary fully self-contained mobile office unit to be on the site for a span of between 6-9 months in the future at a time to be determined. B. Proposed Use of the Property The applicant proposes to use the subject property to support industry, and the applicant's primary use will be a regional supply yard for new and unused materials and equipment used in support of the Oil & Gas industry(OGI). The applicant plans to provide storage of materials including iron, steel and wood supplies. The industries which may store materials on the property may include: (a)oil& gas support businesses, including oil&gas storage and oilfield support(such as downpipe), supplies and services businesses; and (b)the energy industry, including power provider(s), solar provider(s), and/or wind-power provider(s). All items will come in to the site either raw or unfinished and leave the site the same way they came. The yard is not to be used to store junk or salvage or for painting; all stored items are ready for immediate use. The applicant is contemplating an unmanned site that trucks will enter and exit for the purpose of loading and unloading supplies and equipment the above-mentioned supplies and equipment to assigned areas. Applicant anticipates that his employees will from time to time meet trucks at the site for the purpose of directing them to the locations that have been designated for them to offload. The applicant anticipates that 3-4 small diesel-run forklifts will be kept on site and stored on one side of the Quonset hut. These forklifts are to be used to assist with loading and unloading the semi trucks. The trucks are to be fueled by a fuel truck of applicant's that travels from one of his properties to another. Pipe is to be unloaded onto racks made of either metal or rail ties and will be stored off the ground. Pipe will be on the racks and will not be stored the ground. There is an existing Quonset hut on the property that has been used for storage. There is no intended change to the use of the Quonset; rather,the Quonset hut will be used for storage of supplies for support of the oil & gas industry, such as smaller tools or pieces of pipe and equipment. No hazardous materials or waste of any sort will be stored in the Quonset. There will be two signs connected to the property—one sign on the outside the berm on the southeast corner of the property 16 sq. ft. or fewer,and one sign inside the property on the inside of the entry with instructions for drivers. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. The subject property is currently zoned A (Agricultural). One essential goal of the Comprehensive Plan is "to support all forms of the agriculture industry and,at the same time,to protect the rights of the private property owners to convert their agriculture lands to other appropriate land uses." Sec. 22-2-10.B. Conversion of agricultural land to a residential, commercial or industrial use "should be accommodated when the subject site is in an area that can support such development,and should attempt to be compatible with the region." Sec. 22-2-20 G.2. A.Policy 7.2. The proposed use on the site would be highly compatible with the surrounding region, and the area can support such development. The proposed use is not offensive in nature, and impacts to environmental resources such as air, water,noise and public health, if any, should be minimal. The property is screened from public view by an earthen berm approximately 12 feet high, and the largest property in the nearby vicinity is one of the largest feedlots in Weld County,meaning that dense population is hardly likely in the future. These features are in conformity with Section 22-2-150 F.I.Goal 6, which calls for minimizing incompatibilities between industrial use and surrounding properties, supporting visual and sound barrier landscaping, and ensuring that industrial properties are free of derelict vehicles,refuse, and other unsightly materials. The site will have a relatively small footprint, and while there will potentially be some impact on issues such as traffic in the area,these impacts will not change the basic agricultural character of the surrounding area. The site's contribution to safe, low-impact oil and gas transport throughout Weld County will enhance the County. Furthermore, Section 22-2-150 D. I. Goal 4 states, "All new industrial development should pay its own way." The proposed use here meets these criteria, in that all improvements will be paid for without any request from the County for funds. 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. Among other things, under Section 23-3-40 of the Weld County Code, oil and gas support and services are permitted uses, upon approval, in an agricultural zone district. The site would not interfere with any agricultural operations, or with the use or operations of any surrounding property,and the proposed use would be consistent with the zoning provisions of the Code. 4. What type of uses surround the site- explain how the proposed use is consistent and compatible with surrounding land uses. The lots immediately adjacent to the site are agricultural land,with a residence on the lot south of the site, and a residence on the lot west of the site. The proposed use of the site is consistent and compatible with these uses, and is permitted under Section 23-3-40 of the Weld County Code. The proposed use will have a positive impact on Weld County as a whole,and will have little or no impact in terms of government obligations,or changes to the agriculture character of the surrounding properties. 5. Project Details a. Number of people using the site: It is anticipated that while the site itself will be unmanned,there will be approximately 5-6 individuals(i.e.truck drivers and/or lumpers) on site at any one time during regular business hours for the purpose of loading or off-loading trucks. It is not anticipated that any person will be on the site for more than two(2) hours at a time. The maximum number of individuals expected on site at any one time is no more than 20 individuals. b. Number of employees: It is anticipated that while the site itself will be unmanned, there will be approximately 5-6 individuals (i.e. truck drivers and/or lumpers)on site during regular business hours at any given time, none for more than two (2) hours at a time. The maximum number of employees on site at any given time is expected to be no more than 12 individuals at any one time. c. Hours of operation: The site will be open 24 hours a day. However, it is anticipated that the vast majority of activity on the site will take place during daylight hours. d. Type and number of structures to be erected on this site: No construction is proposed at this time,although the applicant anticipates seeking approval at some point in the future to construct at least one additional building on the property that will house between 5 and 6 employees and one additional storage building. e. Although no construction is proposed at this time, applicant seeks approval at this time to place a fully self-contained temporary office trailer on the site in the future; waste will be self-contained in an in-trailer porta-let and sewage will be hauled by the same provider that will service the portable toilets. Potable water will be delivered and waste water will be hauled to/from the trailer by water truck. This fully self-contained temporary office trailer to be present on site for an to-be- determined length of time which may exceed 6 months; applicant shall apply for the appropriate permits at such time as applicant is ready to add the trailer to the site. f. Type and number of animals, if any,to be on this site: N/A g. Type and number of vehicles that will access this site and how often: Materials will be moved onto and off of the site,with approximately 20-30 semi trucks loading and unloading shipments per day. The site will also be accessed by pickup trucks and other personal vehicles of employees. h. Who will provide fire protection to the site: t.b.d.—Fire District Notification Letter will be provided. i. Water source on property: There is a water tap on the site from a prior residential use. However, no water is currently used on site. Current water bill is attached showing that the minimum mandatory fee of$16.50 per month is being paid to keep the tap on and reserved to this site. The tap is currently coded by the Central Weld County Water District for"any use,"which includes residential, agricultural or commercial. j. Sewage disposal system on the property: N/A. There will be porta-lets on the site that are self-contained and will hold hand sanitizer dispensers sufficient for sanitary use. k. If storage or warehousing is proposed, what type of items will be stored: The site will store materials including iron, steel,wood and electrical materials. The site will not be used as a salvage yard or junk yard, and no waste will be stored on site. 6. Explain the proposed landscaping for the site. The site presently has few landscaping features. The applicant proposes that the berm, which is approximately 12 feet high, serve in lieu of fencing as it blocks the site from the view of neighboring properties. The berm is fully seeded with native grasses. 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. The applicant does not anticipate that any reclamation procedures will be necessary, but in the event that they become necessary,the applicant will seek guidance from the County in the event reclamation procedures should become necessary. 8. Explain how the storm water drainage will be handled on the site. The present owners of the site had a soil analysis completed. The majority of the site is covered with vona loamy sand,a soil with moderate water capacity,moderately rapid permeability, slow surface runoff and low risk of erosion. The southern edge of the site has julesburg sandy loam,which is a deep, well drained soil with rapid permeability, slow surface runoff and low risk of erosion. Accordingly, it is anticipated that there will not be significant water drainage on the site. Any drainage that does exist is expected to flow from the southern portion of the site to the northeast corner of the site, where a water quality area has been designated. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. No construction is proposed at this time, although the applicant anticipates seeking approval in the future to construct at least one building on the property. It is anticipated that creation of the water quality area will occur within 90 days of the USR and any necessary permits. 10. Explain where storage and/or stockpile of wastes will occur on this site. No wastes will be stored or stockpiled on the site. While trucks will be present on the site periodically, no washing will occur on the site, and no mechanical work will be conducted on the site. It is anticipated that there will be little waste generated on the site, but any waste that is generated will be removed for disposal according to applicable regulations. 11. Please list all proposed on-site and off-site improvements associated with the use and a timeline of when you will have each one of the improvements completed: There are no off-site improvements anticipated. All on-site improvements have been addressed in Sections 1-10 above. From: Ann Hough To: Tiffane Johnson Subject: RE: USR Application on site RECX13-0080 for Lundvall Date: Thursday,May 29,2014 1:53:04 PM Hi, Tiffane: We included the possible future construction trailer because we were led to understand that if we did not get it approved on the USR app, it would be very difficult to get an approval for one in the future. Therefore, in view of the fact that at some point, the Buyer intends to have a construction project (future office building), we decided to go for it. It is my understanding that it would be used primarily for invitees to the property who would be connected with construction of the building. I do NOT believe that Buyer's employees would use it as an office or that truckers would use it either. As to the future permanent building, it is my understanding that it is mainly to be used for administration, for a total of 5-6 employees who will work inside of it as office-workers. The other 5-6 future employees would be yard workers who would so some work on the premises but not have office space. It is my understanding that they would be full-time hires, but for sure, these 5-6 outside workers would not be spending their entire shifts on the subject property, as the Buyer owns more than one property. All of the above future employees are part of the 12 employees referenced in the application. The site will no longer be unmanned once the building is completed but will be unmanned until that time, even including the time when the trailer is on the site, as the future construction trailer would be used solely for the contractors involved in the build. Question 5(d) states: ... No construction is proposed at this time, although the applicant anticipates seeking approval at some point in the future to construct at least one additional building on the property that will house between 5 and 6 employees and one additional storage building. (this is the proposed office building). As to the proposed future building, we would definitely be putting in a whole separate app, etc. for that when the time comes ... I hope this helps. If there is something I need to clarify, or if you should need additional information, please let me know. Thank you so much for your work on this project, Ann Ann F.

Can you tell me who and how many will use the possible future construction trailer and are they visitors, full time office employees or the truckers/lumpers? What about the future permanent building? In the future, when they are ready to build the permanent office how many employees will that include? Will they be full time. Are they part of the total future 12 employees identified in the application? Describe who the future 12 employees will be and what they do?Are they a combination of onsite and offsite employees? What will the one additional building identified in item 5d. be used for? Will the site continue to be an unmanned facility when the office trailer and or this future building is in place or will it have permanent on-site employees?

We understand that this construction/office trailer is temporary and will need to be removed from the site. At this time, we do not know how many contractors will be on the site to build the permanent building as the structure had not yet been designed. Thanks, Ann Hough Ann F.

TRAFFIC NARRATIVE The proposed project will obtain access off WCR 46. The property is approximately 2,000 ft. east of CR 31. CR 46 is currently utilized primarily by semi trucks, farm vehicles, area residents and other associated traffic. Highway 31 also carries commercial,farm and residential traffic. The peak hours for traffic on CR 46 and CR 31 are estimated to be from 6:00 to 7:30 a.m. and from 5:30 to 7:00 p.m., assuming the highest peak rates would be associated with peak commute hours. The proposed use will contribute approximately 35 trips per day. The overwhelming majority of these trips will come in to the subject property from the East(from Highway 85)and leave the property toward the East. These trips represent a minimal increase in daily traffic on Highway 46. It should be noted that the majority of the trips to and from the proposed use will occur during the day outside of peak hours.

DESCRIPTION OF HISTORIC STORMWATER FLOWS ACROSS THE SUBJECT PROPERTY The attached map contains arrows which indicate the historic stormwater flows across the subject property,which generally move from south to the northwest, ending in the northeast corner of the project. The proposed Water Quality Feature will be located in this northeast corner. No water flows onto the property from any offsite sources because the entire property is surrounded by the berm. Likewise,water has historically evaporated off of the soil or has been absorbed into the soil. However, the Water Quality Feature will provide a specific site on the property for water to collect and dissipate.

No full-time employees will be on site, and few if any part-time (20 hour week) employees would visit the site, most often for periods of two (2) hours or less per day. Likewise, truck drivers or any other contractors would be on the site for less than two (2) consecutive hours per day. No more than ten(10) customers would visit the site per day. Accordingly, Applicant will provide portable toilet(s) at the site. These will be self- contained units that would include hand sanitizers sufficient for sanitary use. POTABLE WATER INFORMATION & PLAN The proposed use is primarily for storage of materials and equipment used in support of the Oil & Gas industry. No full-time employees will be on site, and few if any part-time (20 hour week) employees would visit the site, most often for periods of two (2) hours or less per day. Likewise,truck drivers or any other contractors would be on the site for less than two (2) consecutive hours per day. No more than ten(10) customers would visit the site per day. Accordingly, Applicant will provide bottled water at the Quonset hut storage building that is on the site. DUST ABATEMENT PLAN A. Road Surface: A road extends through the center of the property, and ends with a truck turnaround; both the road and truck turnaround are paved concrete. The entrance to the site is also a paved concrete surface that will mitigate any dust from arriving or departing traffic. B. Surrounding Berm: The property is surrounded by a 12-foot high earthen berm, which serves to block wind and to contain any minimal dust that may be generated from the property. The berm encircles the entire portion of the property that will be active, with the exception of a gap that serves as an entrance point to the site. The berm is seeded and is covered with grass, meaning that a minimal amount of dust, if any,would be generated from the berm itself. C. Gravel Surface: The remainder of the surface area within the borders of the berm, not including the paved road and turnaround,was recently covered with native sand-based gravel. This ground cover will minimize, if not eliminate, any dust generated on the property. D. Activities On Site: All trucks and other vehicles that access the site will only travel on paved roads. Vehicle speeds will be restricted to limit dust generation. E. Observations of Dust On Site: The applicant has submitted pictures from a site visit on a day in which winds were gusting at close to 50 mph. Despite these winds, no dust was visible on site. WASTE MANAGEMENT PLAN No wastes are expected to be generated on site. No chemicals will be stored on site. The proposed use is primarily for storage of materials and equipment used in support of the Oil& Gas industry. No vehicles or equipment will be washed on site. Regarding a motor vehicle oil leak, Applicant's standard operating procedures are to remove the contaminated soil and dispose of it. A 50-Gallon 2-wheel trash can will be placed on site near the Quonset hut, and Waste Management will commence trash pickup.

I understand the the Town of Evans or County of Weld does not and shall not assume liability for the drainage facilities designed by others. George D. Paulsberg, Registered Professional Engineer �,DO REGIsj.' State of Colorado No. 35359 �fo" �o de ,'+ I.' 35359 •- t • 8/ONAL , hereby certifies that the drainage facilities for the Sparrow Industrial Subdivision shall be constructed according to the design presented in this report. I understand that the Town of Evans does not and will not assume liability for drainage facilities designed and/or certified by my engineer. I also understand that the Town of Evans relies on the representations of others to establish that drainage facilities are designed and constructed in compliance with Town guidelines, standards, or specifications. Review by the Town of Evans can therefore in no way limit or diminish any liability,which I or any other party may have with respect to the design or construction of such facilities. Attest: (Name of Responsible Party) Notary Public Authorized Signature —3— January 12,2011 This drainage report is for the development of the Sparrow Industrial Subdivision located in the E 1/2 of SW '/a of Section 10,T.4N.,R.66W, 6TH P.M.,WELD County, Colorado. Since the City of Evans does not currently have drainage criteria, this report was prepared to comply with applicable requirements of the Urban Drainage&Flood Control District. The purpose of this report is to present the drainage impact of the proposed development located adjacent to and north of CR 46 and between CR 31 & CR 33. The anticipated development flows for this project are identified. GENERAL LOCATION AND DESCRIPTION This property is approximately 75 acres located within the boundaries of the City of Evans after annexation, Colorado; see vicinity map on the drainage plan. The site is bordered on the south by CR 46 and on the north, east and west by farmland. The existing site is primarily undeveloped. The existing site drains to the northeast in sheet flow where it ponds and evaporates or percolates into the ground. Overall the site is very flat having only 6 feet of fall over its diagonal length. Initial development is planned for storage of construction materials i.e. power poles and support construction equipment. A 30' wide roadway inside the 60' ROW is planned for immediate construction along with the drainage storage pond. Commercial development will start once the lots are sold. MAJOR DRAINAGE WAYS The South Platte River is north of the project and over 40 feet lower in elevation of the site. However, there is no adequate drainage way to convey storm water from this site to the river. The site does not lie within any FEMA or locally designated flood plain. CRITERIA The basis for this Drainage Report is Urban Drainage and Flood Control District Criteria Manual Section 3.3.4 in Volume 2 of the manual states that a retention facility can be used when there is no available formal downstream drainage way as is the case with this property. The manual further states that the retention basin should be designed to capture 1.5 times the 24 hr., 100 year storm volume. This facility will be designed and built using the above criteria. DESIGN CONCEPT The site generally flows in sheet flow from the southwest to the northeast corner of the property. The retention pond will be located in the northeast corner which is the low point of the property. The maximam slope in the pond will 4:1 and sheet flow less than 0.5%. Sheet flow will be assisted or improved through the use of ditches along side the road construction to direct and channel the flow to the retention pond. Minor swale grading will be needed in three small areas to maintain/direct the flow towards the pond. There is no offsite water entering the property thus keeping the pond to a:minimum size: -4- January 14,2011 DESIGN DETAILS Runoff coefficients are obtained from Table RO-5 of the UDFCD Criteria Manual. An imperviousness value of is assumed for the site and for a 100 yr: Storm the coefficient is 0.42 A check of Figure RO-8 for Type B soils is 0.44. The higher value of 0.44 is selected to use. The 24 Hr, 100 yr. Storm (0.16) is taken from Table 3.3 of the City of Greeley Design Criteria Manual. The required retention pond volume is calculated as follows: Q=CIA= (0.44)(0.16)(69.38)= 4.88 CFS 24 hour volume= (4.88CFS)(60sec/min.)(60min/hr.)(24hrs.) = 422,008 cubic feet Applying 1.5 safety factor=(422,008)(1.5) = 633,012 cubic feet for retention volume. SUMMARY AND CONCLUSIONS The proposed retention pond design will be 220'x420'x12'deep having 3:1 side slopes. The volume of this pond will.be 643,288 cubic feet. 643,288 divided by 422,008 = 1.52 safety factor The ratio of design pond to require pond yields a safety factor of 1.52 over the required 1.5 safety factor. j APPENDIX A •��r • •'-'7,(7._•-•-;‘,„.`.-1•--..-- -;:2.%'•-•''',� �' ��`�-ill f7- o '{fia� '---;- .f r ?5` �, -! *e$r p !f•.i�y3 1,�� •'�._.--" ..-'vr' %,4,NN t ..f II., T..,. rc/ff.'s �,/.---`•-•,._.._______...---',�......_-, ". 4 r"\`I f ' : 11 ii \ N5 fl.'^-r =7"-N",,„..,, I(J 1; T j: .i ) it 1 i •70 t. • It • �1r t" 'in.

Blowing sand and low available water capacity are the principal hazards in establishing trees and shrubs. The soil is so loose that trees should be planted in shallow furrows and vegetation maintained between the rows. Supplemental irrigation is needed to insure survival. Trees that are best suited and have good survival are Rocky Mountain juniper, eastern redeedar, ponderosa pine, and Siberian elm. The shrubs best suited are skunkbush sumac,lilac, and Siberian peashrub. Wildlife is an important secondary use of this soil. The cropland areas provide favorable habitat for ring-necked pheasant and mourning dove. Many nongame species can be attracted by establishing areas for nesting and escape cover. For pheasants, undisturbed nesting cover is essen- tial and should be included in plans for habitat develop- ment, especially in areas of intensive agriculture. Range- land wildlife, for example, the pronghorn antelope, can be attracted by developing livestock watering facilities, managing livestock grazing,and reseeding where needed. This soil has good potential for urban and recreational development. Once established, the lawns, shrubs, and • trees grow well. The chief limiting soil feature is the rapid permeability in the substratum, which causes a hazard of ground water contamination from sewage lagoons. In places recreational development is limited by the susceptibility to soil blowing. Capability subclass IIIe irrigated, We nonirrigated; Sandy Plains range site.

Paulsberg, P.E. 2_ January 11,2011 CERTIFICATION Engineer's Certification I hereby attest that this report for the final drainage design of the Sparrow Industrial Subdivision was prepared by me, or under my direct supervision, in accordance with Urban Drainage & Flood Control District Criteria for the responsible parties thereof. I understand the the Town of Evans or County of Weld does not and shall not assume liability for the drainage facilities designed by others. George D. Paulsberg, Registered Professional Engineer �,DO REGIsj.' State of Colorado No. 35359 �fo" �o de ,'+ I.' 35359 •- t • 8/ONAL , hereby certifies that the drainage facilities for the Sparrow Industrial Subdivision shall be constructed according to the design presented in this report. I understand that the Town of Evans does not and will not assume liability for drainage facilities designed and/or certified by my engineer. I also understand that the Town of Evans relies on the representations of others to establish that drainage facilities are designed and constructed in compliance with Town guidelines, standards, or specifications. Review by the Town of Evans can therefore in no way limit or diminish any liability,which I or any other party may have with respect to the design or construction of such facilities. Attest: (Name of Responsible Party) Notary Public Authorized Signature —3— January 12,2011 This drainage report is for the development of the Sparrow Industrial Subdivision located in the E 1/2 of SW '/a of Section 10,T.4N.,R.66W, 6TH P.M.,WELD County, Colorado. Since the City of Evans does not currently have drainage criteria, this report was prepared to comply with applicable requirements of the Urban Drainage&Flood Control District. The purpose of this report is to present the drainage impact of the proposed development located adjacent to and north of CR 46 and between CR 31 & CR 33. The anticipated development flows for this project are identified. GENERAL LOCATION AND DESCRIPTION This property is approximately 75 acres located within the boundaries of the City of Evans after annexation, Colorado; see vicinity map on the drainage plan. The site is bordered on the south by CR 46 and on the north, east and west by farmland. The existing site is primarily undeveloped. The existing site drains to the northeast in sheet flow where it ponds and evaporates or percolates into the ground. Overall the site is very flat having only 6 feet of fall over its diagonal length. Initial development is planned for storage of construction materials i.e. power poles and support construction equipment. A 30' wide roadway inside the 60' ROW is planned for immediate construction along with the drainage storage pond. Commercial development will start once the lots are sold. MAJOR DRAINAGE WAYS The South Platte River is north of the project and over 40 feet lower in elevation of the site. However, there is no adequate drainage way to convey storm water from this site to the river. The site does not lie within any FEMA or locally designated flood plain. CRITERIA The basis for this Drainage Report is Urban Drainage and Flood Control District Criteria Manual Section 3.3.4 in Volume 2 of the manual states that a retention facility can be used when there is no available formal downstream drainage way as is the case with this property. The manual further states that the retention basin should be designed to capture 1.5 times the 24 hr., 100 year storm volume. This facility will be designed and built using the above criteria. DESIGN CONCEPT The site generally flows in sheet flow from the southwest to the northeast corner of the property. The retention pond will be located in the northeast corner which is the low point of the property. The maximam slope in the pond will 4:1 and sheet flow less than 0.5%. Sheet flow will be assisted or improved through the use of ditches along side the road construction to direct and channel the flow to the retention pond. Minor swale grading will be needed in three small areas to maintain/direct the flow towards the pond. There is no offsite water entering the property thus keeping the pond to a:minimum size: -4- January 14,2011 DESIGN DETAILS Runoff coefficients are obtained from Table RO-5 of the UDFCD Criteria Manual. An imperviousness value of is assumed for the site and for a 100 yr: Storm the coefficient is 0.42 A check of Figure RO-8 for Type B soils is 0.44. The higher value of 0.44 is selected to use. The 24 Hr, 100 yr. Storm (0.16) is taken from Table 3.3 of the City of Greeley Design Criteria Manual. The required retention pond volume is calculated as follows: Q=CIA= (0.44)(0.16)(69.38)= 4.88 CFS 24 hour volume= (4.88CFS)(60sec/min.)(60min/hr.)(24hrs.) = 422,008 cubic feet Applying 1.5 safety factor=(422,008)(1.5) = 633,012 cubic feet for retention volume. SUMMARY AND CONCLUSIONS The proposed retention pond design will be 220'x420'x12'deep having 3:1 side slopes. The volume of this pond will.be 643,288 cubic feet. 643,288 divided by 422,008 = 1.52 safety factor The ratio of design pond to require pond yields a safety factor of 1.52 over the required 1.5 safety factor. j APPENDIX A •��r • •'-'7,(7._•-•-;‘,„.`.-1•--..-- -;:2.%'•-•''',� �' ��`�-ill f7- o '{fia� '---;- .f r ?5` �, -! *e$r p !f•.i�y3 1,�� •'�._.--" ..-'vr' %,4,NN t ..f II., T..,. rc/ff.'s �,/.---`•-•,._.._______...---',�......_-, ". 4 r"\`I f ' : 11 ii \ N5 fl.'^-r =7"-N",,„..,, I(J 1; T j: .i ) it 1 i •70 t. • It • �1r t" 'in.

Blowing sand and low available water capacity are the principal hazards in establishing trees and shrubs. The soil is so loose that trees should be planted in shallow furrows and vegetation maintained between the rows. Supplemental irrigation is needed to insure survival. Trees that are best suited and have good survival are Rocky Mountain juniper, eastern redeedar, ponderosa pine, and Siberian elm. The shrubs best suited are skunkbush sumac,lilac, and Siberian peashrub. Wildlife is an important secondary use of this soil. The cropland areas provide favorable habitat for ring-necked pheasant and mourning dove. Many nongame species can be attracted by establishing areas for nesting and escape cover. For pheasants, undisturbed nesting cover is essen- tial and should be included in plans for habitat develop- ment, especially in areas of intensive agriculture. Range- land wildlife, for example, the pronghorn antelope, can be attracted by developing livestock watering facilities, managing livestock grazing,and reseeding where needed. This soil has good potential for urban and recreational development. Once established, the lawns, shrubs, and • trees grow well. The chief limiting soil feature is the rapid permeability in the substratum, which causes a hazard of ground water contamination from sewage lagoons. In places recreational development is limited by the susceptibility to soil blowing. Capability subclass IIIe irrigated, We nonirrigated; Sandy Plains range site.
