If a question does not pertain to your use, please respond with "not applicable", with an explanation as to why the question is not applicable. 1 . Explain, in detail, the proposed use of the property. The property is approximately 53 acres with a proposed use of a storage yard for piping and equipment in support of oil and gas operations. The proposed hours of operation are seven (7) days a week, 24 hours per day and will be operated by High Plains Disposal, Inc. Trucks will enter and leave using two existing access points, one on County Road 54 and one on County Road 47. No stationed personnel is proposed. Only transient truck drivers to deliver and pick up piping and equipment are anticipated. Since the site does not have permanent facilities, it is not envisioned that the site would have enhanced landscaping other than fenced screening. Additionally, it is not anticipated that the site will have permanent signage, parking spaces, or lighting associated with this USR application. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. Currently the proposed site is zoned agricultural. Per the Comprehensive Plan, industrial development that is not directly related to agriculture is permitted where adequate services exist or are reasonably obtainable. When located properly, industrial development is encouraged because of the economic benefits associated with it. 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. The proposed site is zoned Agricultural and , per Chapter 23 of the Weld County Code, oil and gas storage, support and service facilities are permitted when approved by the Use by Special Review process. 4. What type of uses surround the site (explain how the proposed use is consistent and compatible with surrounding land uses). The proposed site is located approximately 3 miles west of Kersey, Colorado on Weld County Road 54. The proposed site will occupy Lot B of Recorded Exemption 0961 -25-2, RE 4560. The site is surrounded by agricultural land and WCR 47 to the west, agricultural land and WCR 54 to the north, an existing access road along the east side of the property, and a Union Pacific railway and associated 400-foot Right-of-Way along the property to the south. An existing water disposal (injection) facility owned and operated by High Plains Disposal, Inc. is also located adjacent and to the east of the proposed property on Lot A of Recorded Exemption 4519. The proposed use is compatible with the surrounding land uses, given the injection facility on adjacent Lot A and multiple oil and gas well operations that already exist on the proposed USR property. 5. Describe, in detail, the following : a. Number of people who will use this site Primarily, the site will be accessed by transient truck traffic only. It is anticipated that trucks will access the site approximately 60 times per day (round trip). b. Number of employees proposed to be employed at this site Use by Special Review Questionnaire USR 15-0077 High Plains Disposal, Inc., Lot B September 28, 2015 Page 2 of 3 It is expected that there will only be transient truck traffic throughout the hours of operation . c. Hours of operation The facility will be operational from 24 hours per day, 7 days a week. d. Type and number of structures to be erected (built) on this site There are no structures proposed to be built on this site at this time. e. Type and number of animals, if any, to be on this site No animals are expected on this site. f. Kind of vehicles (type, size, weight) that will access this site and how often The kind of vehicles (type, size, weight) that will access this site will be pickups and WB50 tractor semi-trucks with pipe and/or equipment weighing up to approximately 40 tons-loaded at most. These trucks are expected to access the site approximately 65 times per day (round trip). g. Who will provide fire protection to the site The property is located within the Platte Valley Fire Protection District. h. Water source on the property (both domestic and irrigation) Potable and/or irrigation water is not anticipated to be needed at this time. i. Sewage disposal system on the property (existing and proposed) An on-site wastewater treatment (septic) system is not proposed at this time. j. If storage or warehousing is proposed, what type of items will be stored Indoor storage and/or warehousing is not proposed at this time. Only outdoor storage of pipe and other oil and gas related equipment such as tanks, frac tanks, pipe, trailers, skid shacks, trucks, and connex storage boxes is proposed at this time. 6. Explain the proposed landscaping for the site. The landscaping shall be separately submitted as a landscape plan map as part of the application submittal. Landscaping is not proposed for the site except for the installation of screening fence. 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Termination of the Use by Special Review activity is not expected. If required, termination will conform to Weld County regulations. 8. Explain how the storm water drainage will be handled on the site. The majority of the stormwater runoff from Lot B will be collected in two separate ponds at the east end of the property that include the water quality capture volume (WQCV) and pumped onto adjacent Lot A which is also owned and operated by High Plains Disposal, Inc. Stormwater will be pumped onto a level spreader on Lot A to minimize erosion. Stormwater that leaves the level spreader will either infiltrate or convey east and then north to the existing outfall detention control structure. Based on the approved drainage report for Lot A, there is more than enough capacity built into the site's stage-storage to accommodate the additional pumped stormwater. The stormwater on Lot B will be directed by the grading of the site to the proposed collection ponds. Use by Special Review Questionnaire USR 15-0077 High Plains Disposal, Inc., Lot B September 28, 2015 Page 3of3 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. Construction of the site is expected to take approximately two months. Construction is scheduled to begin on approval. No landscaping is proposed but screening fence will be installed toward the end of the construction period . 10. Explain where storage and/or stockpile of wastes will occur on this site. The grading of the property is expected to achieve a material balance such that storage and stockpiling of wastes will only be momentary during grading operations. Only soil material would be stockpiled, if necessary, and only on-site. No other type of waste is anticipated to be stored and/or stockpiled. All polluted runoff from any stockpiled material will be managed through appropriate best management practices (BMP's). 1'. WASTE HANDLING PLAN HIGH PLAINS DISPOSAL, INC.

SITE TRAFFIC The planned facilities will support the oil and gas industry . A & W recently determined that 50 - 60 trucks and 20 employees will use this facility at build out. This updated traffic estimate is documented in the attached email . The site will operate 7 days per week, 24 hours per day . Site access will be provided by two existing driveways : one to CR 54 and one to CR 47 . These driveways are located on CR 47, an estimated 1 , 200 feet south of CR 54 and on CR 54, some 2, 100 feet east of CR 47 . Both CR 54 and CR 47 are paved two lane roadways with collector and local road designations, respectively. Since there are no posted speed limits on these roads in the area of the site, the speed limit is assumed to be 55 MPH . CR 54 is under stop sign control at CR 47 . Truck activity is expected to occur mostly over a 14 hour period from 6 : 00 AM - 8 : 00 PM with random arrivals and departures . This equates to 4 inbound and 4 outbound trucks each hour. Employee work trips will vary based on shift times associated with the site functions . Six yard employees are expected to work up to a 12 hour shift starting at 6 : 00 - 7 : 00 AM with 12 of the 14 office/shop workers expected to work an 8 hour shift starting at about 8 : 00 AM . Site traffic for the high morning and afternoon site peak hours is shown below . One Way Site Trips AM Peak Hour PM Peak Hour In Out In Out Daily Round Trips Trucks 4 4 4 4 60 Employees ( 1 ) 12 -- -- 12 20 TOTAL 16 4 4 16 80 ( 1 ) Peak hours are representative of the shop/office shift change . The above traffic estimates reflect site build out conditions . Based on operator estimates, site traffic will be distributed to CR 47 and CR 54 as follows : To and from the north on CR 47 : 40% To and from the south on CR 47 : 30% To and from the east on CR 54 : 30% The above directional site traffic distributions result in the peak hour and daily traffic demands shown below : ``h,, N co Z 2/7y.

IMPROVEMENTS Turn lane needs related to the A & W facility at buildout were assessed using the Weld County turn lane warrants shown below. • More than 10 peak hour vehicles turning left into the facility warrants a left turn deceleration lane • More than 25 peak hour vehicles turning right into the facility warrants a right turn deceleration lane • More than 50 peak hour vehicles turning right out of the facility warrants a right turn acceleration lane Site traffic was compared to County turn lane warrants at all intersections . This comparison determined that A & W traffic will not warrant any turn lane improvements at site build out. In summary, the above documented investigations indicate that the A & W Water Services project can be served by the existing roadway system . Furthermore, it can be stated that this development is viable from a traffic engineering perspective . I trust this traffic narrative will meet your current needs . Please give me a call if you have any questions or need further assistance . Sincerely, tyl/ 1ne . Cop .

Please proceed with contacting the county for direction on the narrative. Thanks Jeff From: TrafficPE (Gene Coppola) [mailto:trafficpe©comcast. net] Sent: Wednesday, June 17, 2015 2: 12 PM To: Wright, Jeffrey Subject: High Plains Lot B SITE TRAFFIC Hi Jeff. I want to confirm our discussion today about A&W's latest traffic estimates for High Plains Lot B.

Charles Sonnier, Registered Professional Engineer State of Colorado Registration No. 48403 Leaving a Legacy of Enduring Improvements to Our Communities - PURPOSE STATEMENT ENGINEERS SURVEYORS PLANNERS FINAL DRAINAGE REPORT HIGH PLAINS DISPOSAL INC., LOT B, RE-4560 USE BY SPECIAL REVIEW Weld County, Colorado I. Introduction This drainage report presents the drainage plan for High Plains Disposal, Lot B, RE-4560 (Site) within Weld County, Colorado. The purpose of the drainage analysis and design was to verify that the proposed conditions were in accordance with the Weld County drainage criteria and to provide a drainage network that safely and adequately conveys runoff through the site. II. Location A. The proposed site is located approximately 3 miles west of Kersey, Colorado on Weld County Road 54. More specifically, the property is located in the North Half of Section 25, Township 5 North, Range 65 West of the 6th Principal Meridian, Weld County, Colorado. The proposed site will occupy Lot B of Recorded Exemption 0961-25-2, RE 4560. The site is surrounded by agricultural land and WCR 47 to the west, agricultural land and WCR 54 to the north, an existing access road along the east side of the property, and a Union Pacific railway and associated 400-foot Right-of-Way along the property to the south . An existing water disposal (injection ) facility owned and operated by High Plains Disposal, Inc. is also located adjacent and to the east of the proposed property on Lot A of Recorded Exemption 4519. III. Property Description The 53-acre site is currently a fallow cultivated field with native vegetation. Present soils consist mainly of Aquolls and Aquents, gravelly substratum classified as Type-D soils in the NRCS Hydrologic Soils Groups. Refer to Appendix A for soil classification information. The existing topography of the site is essentially flat, gently sloping from southwest to northeast. The proposed use for the property is a storage yard for piping and equipment in support of oil and gas operations. IV. Drainage Basins and Sub-Basins A. Major Basin Description The proposed site is not located within the Weld County Master Drainage Plan . According to the Flood Insurance Rate Map (FIRM ) for Weld County, Colorado, Community Panel Nos. 080266 0639 C and 080266 0645 C, both dated September 28, 1982, the proposed development is located in Zone C. Unshaded zone C is defined as an area of minimal flood hazard ( Refer to Appendix A for the FIRMs) . Copyright Lamp, Rynearson & Associates, Inc., 2015. All rights reserved. September 2015 High Plains Disposal, Inc., Lot B, RE-4560 Page 1 Project No. 0215024.00 B. Sub-Basins Description To the proposed and existing sub-basins, both on-site and off-site flows were considered . Currently the Site slopes slightly from southwest to northeast, eventually conveying runoff to the existing roadside swale that runs along the south side of WCR 54. Once in the roadside swale, the stormwater then conveys east to the intersection of Weld County Roads 54 and 49, ultimately spilling to the Latham Ditch . Due to the surrounding topography, it was determined that no off-site flows affect the Site. Existing topography was evaluated to determine the existing condition sub-basins and flow patterns. Two sub-basins were determined for the existing condition that were denoted as B1 and B2 in this report ( Refer to the Existing Conditions Drainage Basin Map in Appendix A). For the developed condition, the sub-basins were determined from the grading plan, layout of the site, and other factors that determine basin size and shape. These sub-basins were denoted as B1, B3, and B4. Sub-Basins B3 and B4 are sub-basins within sub-basin B2 of the existing condition ( Refer to Developed Conditions Drainage Basin Map in Appendix A) . Impervious values for each basin within the existing and developed conditions were also calculated . The following table is a summary of the existing and developed sub-basins. Existing Condition Basin Area (acres) Impervious (%) B1 5.87 2 B2 41.46 2 Developed Condition B1 5.87 2 B3 23.21 40 B4 18.25 40 V. Drainage Criteria A. Regulations/Development Criteria The developed stormwater conditions were established using information and criteria from the Drainage and Flood Control District's (UDFCD) Urban Storm Drainage Criteria Manual (USDCM ), Urban Storm Drainage Criteria Manual, Volumes I, II, and III, and the Weld County Storm Drainage Criteria Addendum, as well as good engineering practices. B. Hydrologic Criteria The design storms used were the 2-year (minor) and 100-year ( major) for the developed discharges and the 2-year for historic discharge. Because the site is less than 160 acres, the Rational Method was used to calculate historic and developed stormwater runoff. The UDFCD FAA spreadsheet were used to determine the peak flow rates. Copyright Lamp, Rynearson & Associates, Inc., 2015. All rights reserved. September 2015 High Plains Disposal, Inc., Lot B, RE-4560 Page 2 Project No. 0215024.00 C. Hydraulic Criteria The stormwater conveyance systems were designed to capture and convey the minor and major event. The stormwater facilities were designed using techniques developed or adopted by Weld County. Table SO-1 in the USDCM was used to determine the maximum allowable 2- year historic release rate. The UDFCD FAA spreadsheet was used to determine pond sizing. D. Stormwater Quality Stormwater quality will be provided on-site during construction with the use of silt fencing, vehicle tracking devices and sediment control logs. Long-term stormwater quality will be mitigated on site by sheet flow infiltration, water quality control volume (WQCV) provided within the collection ponds and the implementation of a level spreader. VI. Proposed Drainage Design The majority of the stormwater runoff from Lot B is proposed to be collected in two separate ponds, the North Pond and the South Pond, at the east end of the property. Collected stormwater will then be pumped onto a level spreader on adjacent Lot A, which is also owned and operated by High Plains Disposal, Inc. Flow from the level spreader will infiltrate and/or sheet flow to the east side of Lot A and then north to the detention structure. The sub-basins for the proposed development were determined and used to calculate the 100- year peak discharge rates at the respective design points. Time of Concentration was calculated using the methods described in the USCDM . The 100-year peak discharge rates from sub-basins B3 and B4 were calculated to be 31.50 cfs and 39.05 cfs, respectively. A maximum release rate of 2 cfs was determined from Table SO-1 in the USCDM using soil group D and the contributory area . The FAA method was used to determine the required 100-year storage volume in both the North Pond and South Pond . The WQCV was also calculated and provided as part of the 100- year storage volume. A pump is proposed for each pond and will be set to turn on and off above the WQCV elevations to allow infiltration of this volume. Each pump will pump at a rate no higher than 1 cfs (± 450 gpm ) for a total of 2 cfs maximum release rate. Based on the approved drainage report for Lot A titled "Addendum I, Final Drainage Report, USR-1665, High Plains Disposal, Inc., prepared by Lamp Rynearson & Associates, dated March 2009 (2009 Report), there is more than enough capacity built into the site's stage-storage to accommodate the additional pumped stormwater. 2 cfs was added to the 2009 Report FAA calculations to arrive at a revised required storage volume of 63,268 cubic-feet. This was far less than the 80,213 cubic-feet of provided storage on Lot A. Refer to Appendix B for all design related calculations. Copyright Lamp, Rynearson & Associates, Inc., 2015. All rights reserved. September 2015 High Plains Disposal, Inc., Lot B, RE-4560 Page 3 Project No. 0215024.00 The piping from the pumps will be routed to adjacent Lot A where a plunge pool/level spreader will receive the concentrated flow and release as sheet flow. VII. Conclusions In conclusion, the drainage design considerations contained in this drainage report are in accordance with Weld County Drainage Criteria, the USDCM, as well as good engineering practices. Stormwater is proposed to route through the adjacent east Lot A facility (also owned by High Plains Disposal, Inc. ) as it was determined to have more than enough capacity. A majority of the on-site drainage basins and patterns have essentially remained unchanged from existing conditions. The proposed design for the High Plains Lot B drainage improvements provides a safe framework for the drainage in the development. Copyright Lamp, Rynearson & Associates, Inc., 2015.

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 10 Custom Soil Resource Report 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. 11 Custom Soil Resource Report Landform: Swales 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 mapunit.

However, in practice, the time of concentration can be an empirical value that results in reasonable and acceptable peak flow calculations. The time of concentration relationships recommended in this Manual are based in part on the rainfall-runoff data collected in the Denver metropolitan area and are designed to work with the runoff coefficients also recommended in this Manual. As a result, these recommendations need to be used with a great deal of caution whenever working in areas that may differ significantly from the climate or topography found in the Denver region . For urban areas, the time of concentration , tc., consists of an initial time or overland flow time, t,, plus the travel time, t, in the storm sewer, paved gutter, roadside drainage ditch , or drainage channel . For non- urban areas, the time of concentration consists of an overland flow time, t;, plus the time of travel in a defined form, such as a swale, channel, or drainageway. The travel portion, t,, of the time of concentration can be estimated from the hydraulic properties of the storm sewer, gutter, swale, ditch , or drainageway. Initial time, on the other hand , will vary with surface slope, depression storage, surface cover, antecedent rainfall , and infiltration capacity of the soil, as well as distance of surface flow. The time of concentration is represented by Equation RO-2 for both urban and non-urban areas: t, 0 ti tt (RO-2) in which : tc. = time of concentration (minutes) = initial or overland flow time (minutes) t = travel time in the ditch, channel , gutter, storm sewer, etc. (minutes) 2.4. 1 Initial Flow Time The initial or overland flow time, t;, may be calculated using equation RO-3: t _ 0.395 1 . 1 C; /L (RO-3) so.;; in which : = initial or overland flow time (minutes) C; = runoff coefficient for 5-year frequency (from Table RO-5) 2007-01 RO-5 Urban Drainage and Flood Control District RUNOFF DRAINAGE CRITERIA MANUAL (V. 1 ) I. = length of overland flow (500 ft maximum for non-urban land uses, 300 ft maximum for urban land uses) S = average basin slope (ft/ft) Equation RO-3 is adequate for distances up to 500 feet. Note that, in some urban watersheds, the overland flow time may be very small because flows quickly channelize. 2.4.2 Overland Travel Time For catchments with overland and channelized flow, the time of concentration needs to be considered in combination with the overland travel time, t,, which is calculated using the hydraulic properties of the swale, ditch, or channel. For preliminary work, the overland travel time, t,, can be estimated with the help of Figure RO-1 or the following equation (Guo 1999): V C S " l (RO-4) in which : V = velocity (ft/sec) C, = conveyance coefficient (from Table RO-2) S,. = watercourse slope (ft/ft) Table RO-2—Conveyance Coefficient, C,. Type of Land Surface Conveyance Coefficient, C . Heavy meadow 2.5 Tillage/field 5 Short pasture and lawns 7 Nearly bare ground 10 Grassed waterway 15 Paved areas and shallow paved swales 20 The time of concentration , it., is then the sum of the initial flow time, t;, and the travel time, t,, as per Equation RO-2. 2.4.3 First Design Point Time of Concentration in Urban Catchments Using this procedure, the time of concentration at the first design point (i .e. , initial flow time, t,) in an urbanized catchment should not exceed the time of concentration calculated using Equation RO-5. 1 10 (RO-5) 180 in which: t,. = maximum time of concentration at the first design point in an urban watershed (minutes) RO-6 2007-01 Urban Drainage and Flood Control District DRAINAGE CRITERIA MANUAL (V. 1 ) RUNOFF Table RO-3—Recommended Percentage Imperviousness Values Land Use or Percentage Surface Characteristics Imperviousness Business: Commercial areas 95 Neighborhood areas 85 Residential : Single-family Multi-unit (detached) 60 Multi-unit (attached) 75 Half-acre lot or larger * Apartments 80 Industrial: Light areas 80 Heavy areas 90 Parks, cemeteries 5 Playgrounds 10 Schools 50 Railroad yard areas 15 Undeveloped Areas: Historic flow analysis Greenbelts, agricultural 2 Off-site flow analysis 45 (when land use not defined) Streets: Paved 100 Gravel (packed) 40 Drive and walks 90 Roofs 90 Lawns, sandy soil 0 Lawns, clayey soil 0 * See Figures RO-3 through RO-5 for percentage imperviousness.

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 spreadsheet 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 District's web site www.udfcd .org under "Download" — "Technical Downloads." See Examples 7. 1 and 7.2 that illustrate the Rational method . The use of the Rational method in storm sewer design is illustrated in Example 6. 13 of the STREETS/INLETS/STORM SEWERS chapter. RO-10 2007-01 Urban Drainage and Flood Control District STORAGE DRAINAGE CRITERIA MANUAL (V. 2) the calculated 100-year volume. Others require that the 100-year volume be added to the WQCV. All jurisdictions require the WQCV be added to the 5- or 10-year volume. When clear written local criteria on this matter are absent, the District recommends that no less than 50% of the WQCV be added to the calculated 100-year volume for 100-year volumes obtained using empirical equations and the FAA Method. However, unless the local jurisdiction requires adding all or part of the WQCV to the 100-year volume obtained using the simplified Full Spectrum Detention design ; District does not recommend adding any part of the WQCV to the 100-year volume. When the analysis is done using hydrograph routing methods, each level of controls needs to be accounted for and the resultant 100-year control volume used in final design . 3.2 Sizing of On-Site Detention Facilities 3.2.1 Maximum Allowable Unit Release Rates for On-Site Facilities The maximum allowable unit release rates in the Denver area per acre of tributary catchment for on-site detention facilities for various design return periods are listed in Table SO-1 . These maximum releases rates will apply for all on-site detention facilities unless other rates are recommended in a District- approved master plan . For regional facilities see Section 3.2.5. Allowable unit release rates in Table SO-1 for each a soil group in the tributary catchment shall be area- weighted to composite the allowable unit release rate for the total catchment. Multiply this rate by the total tributary catchment's area to obtain the design release rates in cubic feet per second (cfs). Whenever Natural Resources Conservation Service (NRCS) soil surveys are not available, approximate their equivalent types using results of detailed soil investigations at the site.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
