Explain how this proposal is consistent with the intent of the Weld County code, Chapter 22 of the Comprehensive Plan. When we moved here, Monfort's Gillcrest Lot 100,000 head feed lot was west of us on CR 31, Miller's 20,000 head feed lot was one mile East of us. Since it has changed to a Dairy (Vander Desan), then a feed yard on CR 46, Evan's annexed the property north of the tracks, East side of CR 33, Enviro Tech, in which has destroyed the road cleaning or emptying their trucks on it every day. Finally all the neighbors got them to stop. DCP bought the property next to us and put in a gas plant which they leased to us and also worked on Lot B for us. Next ARB and road terminal, then Evan's annexed the road in front of us and across the road, Nikon Terminal (railroad for ARB) then Evan's restricted the bridge across the union ditch which shoves all of the traffic in front of us. The property we bought is next to a USR. A Weld County industrial park is two miles south on Road 33. Two miles South Dan's Garage has been not two miles south of us on road 33 in which he was on rd 44 when we moved here. He opened a RV and Boat Storage 1 mile east of us on hwy 85 and road 46, railroad. The railroad tracks are 1/4 mile north of us and 1 miles east of us. The property starts a half mile in the middle of the section only an easement to get to it, there is not a public road. We have a USR joining us to the South. We have industrial properties to the East of us, city of Evans. We also have a feedlot to the West of us, a pipe yard, Lunval, 34 mile Southwest of us. 3.

Development Criteria Reference and Constraints 1 The historic drainage pattern of the site will be maintained a No significant grading is proposed Any grading will conform as closely as possible to existing elevations Grading will mainly be performed in the areas of the proposed structures and storm water detention facility The vast majority of the property will remain in the existing condition 2 The drainage impact of this site will not adversely affect existing roads or utilities a Due to the limited area of improvements and a minimal increase in imperviousness area, there will not be a significant increase in the rate of runoff generate by the proposed development of the property b The slight increase in runoff that will pass into the proposed storm water detention pond will be insignificant c Onsite detention will be provided to limit the maximum release of stormwater from the site during the 100 -year storm event to no greater than the 100 -year existing rate 3 C. Hydro -logical Criteria 1 The NOAA Precipitation -Frequency Atlas 2 of the Western United States, Volume II was utilized to determine the 1 -hour point rainfall depths a The 2 -year, 1 -hour rainfall depth is 0 84 inches while the 5 -year, 1 -hour rainfall depth is 1 12 inches while the 10 -year value is 1 39 inches and 100 -year value is 2 73 inches 2 The minor storm interval is based on the 5 -year return frequency and the major storm interval is based on a 100 -year return frequency 3 The Rational Method was used to calculated peak runoff rates at various concentration points a The Rational Method is the acceptable runoff method for catchment areas less than 90 acres in size b The worksheets used to determine the peak runoff rates, (see Drainage Calculations in Appendix I of this report), come from the Urban Storm Drainage Criteria Manual The composite imperiousness of a sub -basin was first computed using the worksheets labeled "Area -Weighting for Runoff Coefficient Calculation" The following worksheets labeled "Calculation of a Peak Runoff Using Rational Method" were used to determine the minor and major peak runoff rates The time of concentration used for the existing conditions was the computed Tc, with a minimum value of 10 minutes Because the proposed USR considers one large lot, the Computed Tc was also used as the determining time of concentration for the proposed conditions The Regional Tc value is more often associated with large, compact, urban situations c Table RO-3 from the Urban Storm Drainage Criteria Manual was used for recommended imperviousness values for various land cover A predetermined imperviousness for the residential lots was not used since the density of the lots are much less than the values found in Figures RO- 3, RO-4, and RO-5 in the Urban Storm Drainage Criteria Manual A composite imperviousness was determined for the entire site The remaining area of the lots were considered to be in the existing d The hydrological group 'A' was used in the Urban Storm Drainage Criteria Spreadsheets for the on -site soils On the vast majority of the site, the hydrological group 'A' was used to simulate the Olney loamy sand soils present 4 D. Hydraulic Criteria 1 The contents in the tables, charts, and figures presented in Appendix II, come from the Weld County Storm Drainage Criteria and the Urban Storm Drainage Criteria Manual These diagrams facilitated in the drainage design calculations (Appendix I) 2 Urban Drainage and Flood Control District spread sheets were used to size proposed culverts and structures 3 Proposed culverts have been designed considering Corrugated Metal (CMP) pipe a The Mannings 'n' value for all culvert sizing calculations is 0 025 regardless of pipe material b The required minimum diameter for driveway culverts is 15 -inches with the pipe material considered CMP c The maximum Headwater to Diameter Ratios for roadway and driveway culverts are based on 1 0 during the 10 -year storm event and 1 5 during the 100 -year storm event d When a culverts capacity is exceeded, the over -topping depth across a street during the minor and major storm events is limited to 6 -inches and 18 -inches respectively 4 Recommended Channel Design Roughness Coefficients are per Table MD -1 of the Urban Storm Drainage Criteria Manual Volume I 5 Rip rap outlet protection design comes from Volumes I & II of the Urban Storm Drainage Criteria Manual a From Section 7 3 of Major Drainage - Urban Storm Drainage Criteria Manual Volume I, the acceptable outlet velocity for outlet protection is 5 5 feet per second Rip rap outlet protection at downstream ends of culverts is required only in cases where this velocity is exceeded 6 Roadside drainage ditches and culverts were designed based on a 10 -year storm design frequency a Drainage swales were designed to convey runoff from the 100 -year storm event in addition to capacity for freeboard 5 IV. Drainage Facility Design: A. General Concept 1 Grading will mainly be limited to the areas of the proposed detention pond The historic drainage patterns of the site will be maintained as closely as possible 2 The developed site will drain into the proposed detention pond site The pond is to be regraded and the restricted discharge routed offsite to the east The discharged flow is to be routed to the existing roadside ditch located to the east on the west side of Weld County Road 33 B. Specific Details 1 The Proposed Conditions Drainage Exhibit shows the property considered as one (1) individual sub -basin 2 Sub -Basin `A'(the entire site) contains 13 402 acres The sub -basin produces a peak runoff rate of 0 19 c f s during the 2 -year storm, 0 26 c f s during the 5 -year storm, 0 48 c f s during the 10 -year storm and 4 36 c f s during the 100 -year storm a Storm drainage is to be conveyed overland across the site to the Dentention Pond 3 The Detention Pond has been determined toprovide the following volumes WQCV = 0 027 ac -ft, EURV = 0 032 ac -ft, and 100 Year Vol = 0 212 ac -ft The WQCV and EURV flow volumes are to be retained and permeate through the bottom of the pond in a 12 hour period Excess flows are to discharge through a weir located at the 100 Year elevation The weir discharge is to flow onto existing ground surface V. Erosion Control: A General Concept 1 Temporary erosion control measures will be implemented during the construction of this project These measures will include a Silt fence along the eastern property line b Wattle Dikes are to be installed in the road side swales, at the entrance to all culverts and at the outlet weir flows are to discharge from the pond 6 c Wattle Filter is to be placed at the inlet to the detention pond d A Concrete Wash -out Area is to be provided 2 Long term erosion control measures will be implemented in conjunction with the construction of this project These measures will include a Permanent grassed areas to be seeded b Surface treatments for drives and open storage area 3 Maintenance of all erosion control devices will remain the responsibility of the owner until the completion of the project 4 Wind erosion measures, other than watering down of the site during construction, have been neglected due to the relatively small size of the site r', 5 Permanent water quality measures will be provided by providing sediment storage in the detention pond 6 Since the site disturbance is to exceed one acre, a Colorado State Stormwater Discharge Permit will be required VI Conclusions: A. Compliance with Standards 1 All drainage design conforms to the criteria and requirements of the Weld County Storm Drainage Criteria 2 A separate Erosion & Sediment Control Plan is included that conforms to the criteria and requirements of the Weld County Storm Drainage Criteria and Volume III of the Urban Storm Drainage Criteria Manual a The Erosion & Sediment Control Plan is to outline the temporary measures to be taken during construction activities to control and prevent mud and debris from being washed or tracked onto the adjacent street, properties, and existing drainage features D. Drainage Concept 1 The drainage design for the Ackerman USR is effective for the control of 7 stormwater runoff with little or no effect to adjacent properties or downstream drainage ways a The proposed development will retain the existing drainage patterns The site will continue to drain from southwest to northeast to the detention pond located at the east side of the site b The overall imperviousness of the property will increase from 2 00% (Existing Conditions) to approximately 4 % (Proposed Conditions) This increase will result in more runoff generated by the property (See Drainage Summary) Adequately sized culverts are to be installed at the drainage crossings to accommodate the peak flow rates 2 None of the property hes within a designated FEMA flood hazard area 3 Permanent erosion control and stormwater quality control measures will be incorporated to ensure the quality of stormwater as it exits the site 4 The proposed drainage plans will ensure adequate drainage for the proposed development and will not cause inundation to existing or proposed structures during the 100 -year storm event VI.
