There are four existing structures on site. The property is covered by short planted and native grasses, with trees lining the eastern and northern perimeters and three landscaped areas in the eastern section of the lot. The existing topography depicted by 1 -foot contours is relatively flat with low grades. The high point of the parcel is approximately 5148.2 feet, to the southeast of the existing house. The parcel slopes east to and west, discharging to the drainage ditch running parallel to the north of East 168th Street (County Road 2). 1.2.1 Soil Conditions Soil surveys prepared by the U.S. Department of Agriculture Natural Resource Conservation Service (NRCS) were used to determine soil types and hydrologic soil groups. These data and accompanying reports were downloaded electronically in spatial and tabular format from the NRCS Soil Data Mart website or from the Web Soil Survey. Hydrologic soil groups A, B and C were found on the site and assumed for this project. See Appendix B for NRCS Soil Data. Based on Type A soils (southwest portion of the site) and historic flow analysis, C10=0.01 and C100=0.13 are the runoff values for the existing conditions and C10=0.28 and C100=0.42 in the proposed condition (packed gravel). Based on Type B soils (northwest portion of the site) and historic flow analysis, C10=0.15 and C100=0.48 are the runoff values for the existing conditions and C10=0.38 and C100=0.61 in the proposed condition (packed gravel). Based on Type C soils (eastern portion of the site) and historic flow analysis, C10=0.15 and C100=0.49 are the runoff values for the existing conditions and C10=0.43 and C100=0.65 in the proposed conditions (packed gravel). The soils on site consists of loam, sandy loam and sand. Rational method calculations are located in Appendix A. 1.2.2 Project Description The Project proposes to use the western half of the 5.95 -acre parcel for RV storage and parking. This area will be fenced off and the proposed surface will be 6" of aggregate base coarse (gravel). The proposed pond is on the western edge of the parcel. 2 Preliminary Drainage Report 2.0 DRAINAGE BASINS 2.1 EXISTING DRAINAGE BASINS The existing and proposed drainage basins were split based on soil types. The property drains from the east to the west, so there are no other natural basin divisions. Basins are limited to the proposed development area because the pond has been sized for the proposed development only. 2.1.1 Existing Basin EX -1 Basin EX -1 contains 0.43 acres of B soils in the northeastern portion of the site. This contains the access road and was considered to be "single-family 2.5 acres or larger" with an impervious value of 12%. Peak flows are Q10=0.20 cfs and Q100=1.18 cfs. 2.1.2 Existing Basin EX -2 Basin EX -2 contains 1.14 acres of C soils in the northwestern portion of the site. Runoff for this area was calculated based on historic flow analysis of 2% imperviousness. Peak flows are Q10=0.40 cfs and Q100=2.48 cfs. 2.1.3 Existing Basin EX -3 Basin EX -3 contains 1.80 acres of A soils in the southwestern portion of the site. Runoff for this area was calculated based on historic flow analysis of 2% imperviousness. Peak flows are Q10=0.03 cfs and Q100=1.00 cfs. 2.2 PROPOSED DRAINAGE BASINS 2.2.1 Proposed Basin PR -1 Basin PR -1 includes 0.43 acres gravel including the access road. There is also a small office (8'x8') building that is proposed on the eastern portion of the site. The water flows to the west and empties into the proposed pond in accordance with existing conditions. Runoff coefficients for this basin are Cio=0.38 and Croo=0.61. Peak flows are Q10 = 0.56 cfs and Q100 = 1.70 cfs. 2.2.2 Proposed Basin PR -2 Basin PR -2 is the northwest portion of the property encompassing 1.14 acres. The water flows to the south and outfalls to the proposed pond in accordance with existing conditions. Runoff coefficients for this basin are Cio=0.43 and Cioo=0.65. Peak flows are Q10 = 1.34 cfs and Q100 = 3.82 cfs. 2.2.3 Proposed Basin PR -3 Basin PR -3 is the southwest portion of the property and encompasses 1.80 acres. The water flows to the west and discharges into the proposed pond within the basin in accordance with existing drainage patterns. Runoff coefficients for this basin are Cio=0.28 and Croo=0.42. Peak flows are Q10 = 1.41 cfs and Q100 = 3.93 cfs. 3 Preliminary Drainage Report 3.0 DRAINAGE DESIGN CRITERIA 3.1 REGULATIONS Regulations applicable to the project include the criteria of Weld County, and UDFCD. Per the Weld County Engineering and Construction Guidelines, Policies and technical criteria not specifically addressed in these Criteria will follow the provisions of the Urban Drainage and Flood Control District (hereafter called UDFCD) "Urban Storm Drainage Criteria Manual" (hereafter called Manual). 4.0 DRAINAGE FACILITY DESIGN 4.1 GENERAL CONCEPT 4.1.1 Drainage Patterns The runoff sheet flows to the southwest in existing and proposed conditions. There is no formal collection or conveyance system for stormwater onsite. 4.1.2 Proposed Drainage Pond The site gradually slopes (-2%) from east to west. Determining whether a fully draining extended detention basin (EDB) was viable was the purpose of this study. Because of the outfall constraints, a shallow pond is proposed. Criteria and limitations are listed below: • EDB designed based on UDFCD Detention Volume Spreadsheet (v3.07) • L/W ratio is 4:1 • Main Basin Slopes are 3:1 • Detention Depth is 1.5' and spillway is 0.5' above the 100 -year WSEL • The pond volume was sized to detain the 1 -hr, 100 -year post -developed storm • The pond outlet structure was sized to release the 1 -hr, 10 -year predeveloped storm Limitations: • No trickle channel or micropool has been incorporated. • Outfall requires building infrastructure within the Public ROW (manhole and storm drain pipe) and will therefore require a drainage and maintenance easement 5.0 CONCLUSIONS The proposed drainage pond (EDB) design accommodates the proposed development. The purpose of this preliminary study is to provide enough information to determine if the solution is acceptable to the jurisdiction. If the concept and limitations listed above are approved, the applicant will move forward with a drainage design and study in accordance with USR drainage requirements. 4 Preliminary Drainage Report 6.0 REFERENCES 6.1 URBAN DRAINAGE FLOOD CONTROL DISTRICT VOLUMES 1, 2 (JAN. 2016) AND 3 (NOV. 2015) 6.2 UDFCD SOFTWARE ACCESSED ONLINE JAN 10, 2019. 6.3 UDFCD GIS MAPPING ACCESSED ONLINE JAN 10, 2019. 6.4 WELD COUNTY ENGINEERING AND CONSTRUCTION GUIDELINES (APRIL 2012 UPDATED JULY 2017). 6.5 WELD COUNTY MUNICIPAL CODE (ACCESSED ONLINE JAN. 10, 2019) 5 Preliminary Drainage Report Calculation of Peak Runoff using Rational Method A.(-2.. ul.e 1r.i 921^' j' • .a. h, w'a Wengn 2.00 reW.elMn 2052 <dt Olt .

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation. are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A. B, C. and D) and three dual classes (A/D. B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep. moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. 54.2% 18.5% 27.4% 100.0% tsDA Natural Resources Web Soil Survey a Conservation Service National Cooperative Soil Survey 8/6/2018 Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part 20995 WCR 2 Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff None Specified Tie -break Rule: Higher USDA Natural Resources Web Soil Survey a Conservation Service National Cooperative Soil Survey 8/6/2018 Page 4 of 4 8/6/2018 Property Report Weld County PROPERTY PORTAL Property Information (970) 400-3650 Technical Support (970) 400-4357 Account: R6479386 August 6, 2018 Account Information Account Parcel Space Account Type Tax Year Buildings Actual Value Assessed Value R6479386 147333000057 Residential 2018 4 466.079 33.560 Legal 10884-B PT SE4 33 1 65 BEG N0D24'W 30' & W30' FROM SE COR OF SEC CONT W ALONG N LN OF AN EXISTING R/W 850.08' THENCE N0D24'W 330' S850.08' TO EXISTING R/W S0D24'E 330' TO BEG (.50R) Subdivision Block Lot Land Economic Area 5202 EA 5 FAR OUT Property Address Pr ZipZip Section Township Range 20995 COUNTY ROAD 2 WELD 33 01 65 Owner(s) Account Owner Name Address R6479386 DOUGHERTY KEVIN E 20995 COUNTY ROAD 2 BRIGHTON.
