Rademacher Business Park Final P.U.D i 1/15/2006 Lot 6 of Block 1 1. Project Location and Description Kings Court Business Complex is a 12.91-acre site located on Lots 7 through 10 of Block 2 of the Amended Plat of the Rademacher Business Park Final P.U.D. which is located in the Northwest Quarter of Section 23 Township 3 North, Range 68 West of the 6th Principal Meridian, Weld County, Colorado. Lot 7 through 10 is situated south of Weld County Road (WCR) 32 and west of WCR 9 'A. Lots 7 through 10 are arranged around the Kings Court cul-de-sac to the north of Camelot Circle. A vicinity map is included on the following page for reference. This report will address storm drainage from the four lots contiguous to Kings Court. The storm drainage from the developed portions of the four lots will be detained in a common detention pond on Lot 5 Block 2 and released at the acceptable rate for these lots. Lots 7 and 10 will be developed upon approval of the drainage plan and construction documents. Lots 8 and 9 will be graded and storm sewers extended but will remain undeveloped until these lots are sold. All disturbed areas will be revegetated in the interim. 1.1. Existing Conditions The current conditions of the lots consist of vacant land with light grass and weed cover. The land surface generally drains north away from the Camelot Circle (south of the lots as shown on the Drainage Plan at the back of this report) to the Baugh Lateral irrigation ditch which crosses under Interstate Highway 25 and runs parallel and south of Weld County Road 32 as it drains to the east. The estimated average land surface is 2 to 3 percent. The Soils at the surface consist of a clayey loam material with a moderate erosivity for both wind and water. The Baugh Lateral Irrigation Ditch has been modified under the Rademacher Business Park Master Drainage Plan to increase the capacity of the ditch. This was done to allow the ditch to accept and convey storm drainage runoff form the land to the south as it is developed. Camelot Circle, forming the southern boundary of lots 7 and 10 and Kings Court separating these two lots are built on a fill embankment of 2 to 3 feet of native material to this area. The roads consist of a two-lane, urban road with parking. Camelot Circle has curb and gutter on both sides and a high point at the intersection with Kings Court. Storm drainage from Camelot Circle is collected in two type 'R' inlets at the sag curve sump approximately located at the property line between Lots 10 and 11of Block 2 as shown on the Drainage Plan attached to the back of this report. These inlets drain through an 18-inch pipe to a swale that runs north in an easement along the property line between Lots 10 and 11.

Proposed Condition Kings Court Business Complex is proposing to develop Lots 7 through 10 into four office buildings, one on each lot. The development will create approximately 82 percent imperviousness across the four lots. The impervious area includes asphalt parking and proposed buildings. Two new entrances will be developed from Camelot Circle to Lots 7 and 10 which will allow storm drainage to flow directly from the road to the parcels. Drainage from Kings Court and the area of Camelot Circle adjacent to Lots 7 and 10 and upstream of the entrances will be collected and conveyed through the site to the new detention pond to be located along the south side of Lot 5 Block 2 along with flows from the developed lots. Following sections will describe the basin in detail. 2. Basis for Design The basis for the storm runoff design was taken from the Master Drainage Plan and Report for Rademacher Business Park P.U.D. (LMMDP) prepared by Landmark Engineering Ltd. For Zeek Properties dated October 1996 and the Weld County Drainage Criteria. 2.1. Master Drainage Plan and Report for Rademacher Business Park P.U.D 2.1.1. Basin Delineation The LMMDP for the Rademacher Business Park P.U.D broke the entire 143-acre site into two sub-basin areas. Basin 1 consisted of those areas south of, and tributary to, the Baugh Lateral Ditch. Basin 2 consisted of the areas north of, and draining away from, the Baugh Lateral Ditch to culverts under Weld County Road 32 and ultimately a regional drainage swale a short distance to the north. Basins 1, draining into the Baugh Lateral ditch drains east to WCR 9 'A through the improved section of ditch. The Baugh Lateral ditch flows under Interstate Highway 25 are limited by the 24-inch diameter CMP pipe under the highway. To the east of the highway, the ditch was improved to provide a capacity of 100 cfs to the east side of WCR 9 '/2 . East of WCR 9 % , irrigation and storm drainage flows are conveyed a mile east to a sod farm where they are consumed. It is not clear from the LMMDP if the Baugh channel has a 100-cfs capacity beyond WCR 9 %. Should there be insufficient capacity in the ditch beyond WCR 9 %, then the excess flow will spill to the barrow ditch of WCR 9 1/2 to be conveyed north to WCR 32. At WCR 32 flows mix with those from Basin 2 (areas north of the Baugh Lateral) and then drain to a eastward trending tributary to Lake Thomas as shown on the Vicinity Map included with the LMMDP. Cold Storage Lot 6 3 1/15/2006 Lot 6 of Block 1, Rademacher Business Park Final P.U.D 2.1.2. Allowable Release Rate Lots 7 through 10 of Block 2 are located in Basin 1 and drain to the Baugh Lateral Ditch as shown on the Drainage Plan. Per the LMMDP this area shall be detained a release at a rate equal to the 2-year historic runoff for the area tributary to the ditch. From the LMMDP, the tributary area to the ditch is 96.7 Acres and the 2-year historic storm run off rate was estimated at 23.0 cubic-feet-per-second (cfs). This equates to an allowable release rate of 0.238 cfs/acre. 2.2. Site Constraints Lots 7 through 10 are constrained by their location separate from the Baugh Lateral Ditch to which they will discharge. The plan for these lots is to drain into a regional detention / water quality pond to be located on Lot 5 of Block 2. The discharge from the pond will be release through Pipe Run A along the existing 20-foot wide drainage easement along the west side of Camelot Court. Storm flows from Lots 7 through 10 will be collected in CDOT type 'R' sump inlets located throughout the development and conveyed to the pond in Pipe Runs B and C. This configuration is shown on the Drainage Plan. 2.3. Drainage Criteria This drainage evaluation follows the criteria laid out in the Landmark Engineering Master Drainage Report. Hydrology and Hydraulic calculation shown in Appendix A is base on the Weld County Addendum to the Urban Drainage and Flood Control District Criteria (WCSDC). 3. Storm Drainage Design The general concept for the drainage design for Lots 7 through 10 of Block 2 consist of creating Detention Pond 5 along the south property line of Lot 5 as shown on the attached Drainage Exhibit. Lot 5 is owned by the developer and will be replated with this effort to dedicate Pond 5 as a drainage easement. This pond will detain storm runoff to the 100-year event and release at the 2-year historic rate (0.238 cfs/ac) the areas tributary to the Baugh Lateral ditch as dictated in the LMMDP. Detention of the storm flows will be achieved by constricting the outlet pipe to a maximum discharge under the maximum head using an orifice plate bolted to a headwall. A minimum of one-foot freeboard depth from the 100-year detention pond surface to the top of the berm will be created with the grading of the pond. The pond shall be constructed with an emergency spillway with a hardened concrete cutoff weir section size to spill the 100-year flow into the pond (80 cfs) at a depth of less than 6-inches. The down stream face of the emergency spillway will be protected with angular riprap. Emergency flows will be routed to the Baugh Lateral Ditch via Camelot Circle. Modified FAA/ Rational Method Runoff Calculations Cold Storage Lot 6 4 1/15/2006 Lot 6 of Block 1, Rademacher Business Park Final P.U.D The rational method was used to estimate the runoff to the proposed detention pond. The composite 'C' values for the areas tributary to Ponds 5 were estimated from areas taken from the proposed plans for the access paving, buildings and detention areas. The values used in the estimates of detention are summarized and detailed in the calculations in the Appendix A to this report. 3.1. Required Detention Volume The Denver Urban Drainage and Flood Control District, FAA Detention Volume spreadsheet was used to track the mass balance of the stormwater runoff into and from Detention Pond 6. A print out of the spreadsheet and graph of the mass balance is provided in the Appendix A. Based on this analysis, the required detention volume in Pond 5 is: • Pond 5: 127,791 Cubic Feet or approximately 2.933 Acre-feet 3.2. Available Detention Pond Volume The proposed detention pond grading plan was evaluated for volume and found to provide sufficient storage volume for the 100-year storm event at the allowed release rate. The maximum 100-year stage of the pond is estimated to be 4957.00. The top berm elevation will be a minimum of one foot higher than the maximum 100-year water surface. The crest of the emergency spillway will be set at 4957.00 and the crest of the berm at 4958.0 feet. A concrete weir section and rip rap rundown protection will be included at the outfall of the emergency spillway. The location of the emergency spillway is shown on the Drainage Plan, Sheet 1. Cold Storage Lot 6 5 1/15/2006 Lot 6 of Block 1, Rademacher Business Park Final P.U.D 3.3. Orifice Plate Sizing Standard orifice equations for a sharp plate were used to calculate the necessary opening size at the primary spillway for the Pond 5. The calculation was based on the allowable release rate of 3.0 cfs and the maximum 100-year water surface detailed above and solved for the allowable orifice area shown below. The actual calculations. are included in the Appendix A on the detention spreadsheet. • Pond 6: Rectangular opening 5.00-inches wide and 7-inches high providing 35 square inches at a maximum head of 6.5 feet allows a maximum discharge of approximately 3.0 cfs. 3.4. Down Stream Channel Design The primary spillway from Pond 5 connects to the Baugh Lateral Ditch Via an 18-inch RCP detail as Pipe Run A on the construction Plans. The emergency spillway will spill to the west flowline of Camelot Circle. Flows will then enter the Baugh Lateral and flow east to WCR 9 ''A where flows will spill to the barrow ditch and flow north to WCR 32. 4. Erosion and Sediment Control The Soils at the surface consist of a clayey loam material with a moderate erosivity for both wind and water. The vegetative cover is fair allowing significant soil exposure to erosive forces. During the construction phase the control and practice measures shown on Sheet 2 should be implemented to prevent unnecessary loss of soil from the site. This plan will be used as the basis for a SWMP for the construction site.

The development of the recommendations is presented in the following sections of the report. Introduction The Rademacher Business Park P.U.D. is a proposed 143 acre business park in Weld County, Colorado. The proposed development is located on the East side of Interstate 25 and is bounded on the North by Weld County Road 32 and on the East by County Road 9 1/2. Access to the site is from the frontage road situated between I-25 and the project site. This Master Drainage Plan and Report covers the general drainage patterns for the overall site, and it is proposed that a final drainage study be prepared for each lot as a part of the individual development plans. The final drainage study shall address specific site drainage patterns and facilities based on the final grading and development plans, and must he in compliance with requirements of this Master Drainage Plan and Weld County Criteria. The purpose of this Master Drainage Study is to provide general drainage planning for the overall development. This includes identifying and defining conceptual solutions to drainage problems which may occur onsite and offsite as a result of this development, and identifying drainage structures and other drainage features which should be included in the development plans to provide a complete, safe and economical drainage system design. A fundamental objective of this drainage study is to develop a visionary drainage plan that can be understood and adopted and can be implemented and controlled effectively. This Drainage Study evaluates the existing drainage patterns of the site and identifies future drainage patterns for the development based on the project layout, the grading plan, and other existing site constraints. This includes evaluating historical runoff, investigating routing for design storms through the development, determining what improvements and structures are necessary along with required design capacity, and evaluating offsite drainage which may affect or be affected by the development. The policy and guidelines outlined in the Weld County Subdivision Regulations and technical data from the Larimer County Storm Water Management Manual have been utilized for planning drainage facilities. A major storm drainage system and a minor storm drainage system have been planned as shown on the Master Drainage Plan. The major storm drainage system has been designed to convey runoff from a 100-Year storm through the development in a manner which minimizes health and life hazards, damage to structures and interruption to traffic and services. The minor storm drainage system has been designed to convey nnoff 1-1 from a 2-Year storm, and/or nuisance flows, through the development with a minimum disruption to the urban environment. Findings, Conclusions and Recommendations The principal findings conclusions and recommendations which arise out of this Drainage Study are presented below. These findings are supported by the detailed material presented in the body of the report. 1) Offsite Drainage and Existing Drainage Patterns. Offsite drainage tributary to the project site consists of storm runoff from the K cC Motors property which is located adjacent to the Southwest corner of the site, and runoff from approximately 15 acres situated adjacent to the South boundary of the site. ,Currently storm runoff from these two offsite areas and from about 96.7 acres of onsite area, drains in a Northeasterly direction following existing surface drainage patterns to the Baugh Lateral Ditch. The Baugh Lateral Ditch meanders across the site from a point near the Northwest corner to approximately the midpoint of the East boundary line. Based on calculations presented in the appendix the two year historical release rate for the 96.7 acres of onsite area which drains into the Baugh Lateral Ditch is 23.0 CFS or .238 CFS/AC. As can be seen on the Master Drainage Plan, it is proposed that a swale be constructed along the South boundary line to divert drainage from the area South of the site East to the Roadside Ditch for County Road 9 1/2. This storm runoff could then flow North to the Baugh Lateral Ditch. The storm water release from K&C Motors has been routed through the site to discharge points into the Baugh Lateral Ditch. It is proposed that each individual lot be required to detain storm runoff and release it to discharge points at a rate not more than the historical 2 year flow rate. Currently, there are two (2) storm water discharge points for the site area that is North of the Baugh Lateral Ditch. As can be seen on the Master Drainage Plan, there is a 12" CMP which crosses County Road 32 at a point along the North boundary of Lot 6, Block 1. The tributary area for this culvert is Lots 4-7, Block 1. It is proposed that as these lots develop, they be required to limit storm water runoff to a pro rated share of the capacity of the 12" CMP. Based on calculations shown in the appendix, this establishes an allowable release rate of 0.2055 CFS/ acre. There is also a 12" CMP which crosses County Road 32 at a point near the Northeast corner of Lot 2, Block 1. The tributary area for this culvert is Lots 1-3, Block 1. It is proposed that as these lots develop, they be required to limit storm water runoff to a prorated share of the capacity of the 12" CMP. Based on calculations shown in the appendix, this establishes an Allowable Release Rate of 0.283 CFS/acre. 1-2 2) Baugh Lateral Ditch As can be seen on the Master Drainage Plan, the Baugh Lateral Ditch meanders across the project site from the Northwest corner to approximately the midpoint on the East boundary line. It is proposed that a concrete liner be installed in this ditch and that it be re-aligned to be within an 80 foot wide easement as shown on the subdivision plat. The ditch has historically intercepted storm runoff from about 97 acres of the project site area and storm runoff from any tributary offsite area. Because this ditch has historically accepted storm ruhoff from the project site, and based on conversations with representatives the Ditch Company, it is proposed that onsite detention be required to limit the discharge into the ditch to not more than the historical 2 year peak flow rate for the onsite area. Drainage structures have been planned and designed as shown on the Master Drainage Plan to control the flow and discharge points into the ditch. Based on calculations shown in the appendix, the historical 2 year peak flow rate for the onsite area is 23 CPS or 0.238 CFS/acre. It is proposed that as each individual lot develops, it be required to submit a drainage plan to the Ditch Company and Weld County for approval. This Drainage Plan must detail the detention requirements based on a storm water release rate of 0.238 CFS/acre for a 100 year storm and the proposed individual site development plans. The allowable Release Rate for each lot is shown on the Master Drainage Plan. Based on conversations with representatives from the Ditch Company, the new ditch section has been designed to have as a minimum, the same capacity as the existing ditch section. Based on existing topographic and a typical cross-section, the existing ditch has capacity for about 100 CFS at bank full conditions. The proposed ditch section is concrete lined for a depth of 2 feet. The concrete liner has a bottom width of 4 feet and 1.25 to 1 side slopes. The top 2 1/2 feet of ditch section is grass lined and has been designed with 4:1 side slopes. The total capacity of the proposed ditch section is about 123 CFS at bank full conditions. The ditch crossings and culverts have been designed with minimum capacity of 100 CFS. 3) Detention Facilities The allowable release rate for each individual lot has been shown on the Master Drainage Plan. The approximate storm water detention volumes for each lot have also been indicated and are based on a site runoff coefficient of 0.75. The final runoff coefficients may vary depending on final individual site conditions, therefore, the final detention volumes may vary slightly from those indicated on the Master Drainage Plan. The final detention volumes for each site must be determined as a part of final site design for each site. 1-3 Onsite Storm Drainage System The onsite storm drainage system consists of roadside swales which drain to discharge points into the Baugh Lateral Ditch and to existing drainage crossings at County Road 32. These swales have been designed with minimum capacity for proposed release rates from the tributary onsite area with an allowance for existing flows from the tributary - offsite areas. The required drainage structures, such as swales, street crossings, storm drains and drainage ways should be constructed along with the streets and overlot grading. The developers of individual lots will then be required to route storm water to these design points by approved methods compatible with the grading and development plan, Weld County drainage criteria and other requirements presented in this report Sl Erosion and Sediment Control Plan The following describes the proposed measures for controlling Onsite erosion and sedimentation onto downstream property, during construction. It is proposed that soil exposure be kept at a minimum during overlot grading and straw bale dikes, silt fences and/or sediment ponds where practical be used to filter storm water prior to discharge into the existing downstream drainage facilities. The final details of the erosion control plan should be included in the final construction plans and in the Final Drainage Report for each individual site development plans. 1-4 • SECTION 2 PROJECT DESCRIPTION This project description defines the limits and general topography of the study area and provides a description of the proposed development. Location and Project Description The study area for this drainage evaluation is the area within the boundary of Rademacher Business Park PLED, and the surrounding areas which drain to the site. The site is located on the East side of Interstate 25 and is bounded on the North by Weld County Road 32, on the east by Weld County Road 9 1/2, and on the South by Sekich Subdivision. The project site is located in the NW 1/4 of Section 23, Township 3 North, Range 68 West of the 6th P.M., in Weld County. Access to the site is from the existing frontage road along the East side of Interstate 25. The proposed business park consists of 26 lots averaging about 5 1/2 acres/lot and includes the construction of streets and necessary utilities to serve the development. The topography of the site generally slopes from Southwest to Northeast at about 2% and historical drainage for the part of the site is by sheet flow into the Baugh Lateral Ditch which is situated across the Northern part of the proposed development. The remaining site area drains Northeast to existing drainage crossings at Weld County Road 32. A master grading and drainage plan has been developed and has been used as a basis for drainage planning within the development. Proposed construction included the re-alignment of the Baugh Lateral Ditch and the installation of a concrete lining in the ditch. Several street crossings and storm water discharge points are proposed as a part of the design for the new ditch. • 2-1 • ".,c _ . r 1O I :IC _11-- '\4 tr II Jis ' V _( —, (IIIII- IA : �` NJfr �� 14 I �_-- - — ,I II = Lake h'Larie �� :`,, 0 1 - ,_,7,2_,„,,,____,,,:,-,6� ,I � � r, n Mr2d d�5I I ITTTH "1 .� �a -—__ _ �- I.: L'1I ', 4\' 1ST j ) H i % / / ..--- / VCr �> A,7 I�� , \II _____Y/ / / fj ) , i ' y) - Thomas Z.T.---5—_,\Sji /(//ii I fl/' ) ,�,�) I ,-� ,.�� ,/ i _/' .� �'� v �� „� Pearl Howl r. i I.

PROL. . 1 SECTION 3 DRAINAGE DESIGN CRITERIA A This development of drainage design criteria establishes the methods, procedures and guidelines used to perform the drainage analysis and develop the drainage plan. i Criteria Reference The policy and guidelines outlined in the Weld County Subdivision Regulations along with technical data from the Latimer County Storm Water Management Manual have been utilized for planning drainage facilities for The Rademacher Business Park. Two separate drainage systems have been planned and designed for this development. The minor drainage system has ibeen designed to convey runoff from a 2-Year storm utilizing storm drains and the street cross- sections within acceptable depth criteria. The major drainage system is designed to convey runoff from the 100-Year storm utilizing the minor storm drainage structures and the street section within acceptable depth criteria. IDesign Storms Based on information in the Precipitation-Frequency Atlas of the Western United States, I Volume III the storm isopluvials between Denver and Loveland generally follow Interstate 25. Therefore the tabulated design storms for the City of Loveland have been used as a basis for drainage planning within this development. For this project, a minor storm is identified as a I2 hour design storm with a recurrence interval of 2 years and a total rainfall depth of 1.18 inches, A major storm has a recurrence interval of 100 years and a total rainfall depth of 3.01 inches for a 2 hour storm. These storms have been used as a basis for planning and system design. The peak flow rates for design points have been calculated based on the rational method with a storm duration set equal to the time of concentration for each sub-basin. I Detention Ponds The proposed detention ponds have been sized based on the Modified Rational Method for determining detention pond volume requirements. The Modified Rational Method develops a family of hydrographs based on the peak flow rates for rainfall intensity averaging periods. The proposed maximum release rate from the detention pond is then superimposed on the hydrographs and the required detention storage for each hydrograph is approximated as the area beneath the hydrograph and above the proposed maximum release rate. 3-1 This procedure slightly under estimates the required storage volume because the actual release is a curvilinear outflow hydrograph. However, because the release rate is small compared to the peak discharge of the inflow hydrograph, the resulting volume error is small compared to the volume of storage required. Swale Ca aci The primary function of the swale system is to provide an emergency passageway for major flood flows and Offsite flows with minimal damage to adjacent property. The capacity of the proposed swale sections has been evaluated based on uniform flow as determined by the Mannings Formula which is presented below: Q (1.49/N)ARv3Svz Where Q Discharge in CFS N = Roughness Coefficiency (.035 for grass) A — Area in Square Feet R = Hydraulic Radius (A/P) p = Wetted Perimeter S Slope of Energy Grade Line 3-2 SECTION 4 DRAINAGE FACILITY DESIGN • This section describes the drainage facilities shown on the Drainage Exhibit and explains how storm water will be routed through the development. General Concept The master drainage plan for Rademacher Business Park is to require individual site detention with a 2 year historical release rate. Existing drainage patterns and discharge points are maintained where practical. The Baugh Lateral Ditch effectively divides the site into two (2) separate drainage basins which are discussed separately as follows: Area south of Baugh Lateral Ditch There are about 96.7 acres lying South of the Baugh Lateral Ditch which have historically followed existing surface drainage patterns draining into the ditch. It is proposed that a concrete liner he installed in the ditch and that the ditch be re-aligned to be within a new 80 foot wide easement as shown on the subdivision plat and on the Master Drainage Plan. Storm water discharge points may be constructed at various points along the ditch to accept runoff from the area south of the ditch. It is proposed that each individual site be required to detain storm water and release it to proposed drainage ways at a controlled rate equal to the historical 2 year peak flow. The Master Drainage Plan has identified release rates and approximate detention volumes for each lot. The detention volumes have been calculated using a runoff coefficient of 0.75. These volumes may vary depending on the details of each site plan; however, the release rate should not exceed those values shown on the Master Drainage Plan. Area north of Baugh Lateral Ditch There are about 38 acres north of the Baugh Lateral Ditch that drain to two (2) separate culverts which cross County Road 32. As can be seen on the Master Drainage Plan, Lots 1-3, Block 1 drain to one 12" CMP located near the northeast corner of lot 2, the total tributary area to this discharge point is about 15.9 acres. The prorated release rates and approximate individual site detention volumes for each lot have been shown on the Master Drainage Plan. It is proposed that each lot he required to control the storm water release rate to not more than the values shown on the Master Drainage plan. 3-3 Lots 4-7, Block 1 currently drain to a 12" CMP located along the North boundary of Lot 6. The total tributary area to this discharge point is about 21.9 acres and prorated release rates and approximate individual site detention volumes for each lot have been shown on the Master Drainage Plan. 3-4 SECTION 5 EROSION AND SEDIMENT CONTROL This section describes methods which are recommended to control wind erosion, water erosion and sediment during and after the construction of drainage structures, and site grading. Discussion The clearing and stripping of land for site grading, overlot grading, or for the construction of drainage structures, and swales, may cause high localized erosion rates with subsequent deposition and damage to Offsite properties. Uncontrolled, such erosion could destroy the aesthetic and practical values of individual lots, and cause damage to downstream property. In general, the erosion and sediment control measures may consist of minimizing soil exposure, controlled runoff across exposed areas, and sediment control at drainage structures. Each of these measures is described below and should be utilized by individual lot owners as well as the developer during any construction activity which occurs at this site. General Erosion and Sediment Control Measures Minimizinn Soil Exposure: Where practical, the construction area and duration of soil exposure should be kept to a minimum. All other areas should have a good cover of vegetation or mulch. Grading should he completed as soon as possible after it is begun. A temporary cover crop, a permanent vegetative cover crop, or other landscaping should he established in the disturbed areas. Revegetation may consist of native grasses, lawn grasses, or various winter wheat. Decorative rock, flower gardens, or shrubs may also be utilized in the final landscaping to cover the soil. Reseeded areas should be mulched with straw or hay to protect exposed soil until vegetation is established. Controlled Runoff Across Exposed Areas: Where practical, construction may include constructing temporary swales to intercept and direct storm water around exposed areas. Swales can be constructed to control surface water which collects on exposed areas and prevent gross erosion in the form of gullies. Riprap or other temporary erosion control devices may be installed to control storm water velocities across exposed areas. Sediment Control: Temporary and/or permanent sediment control devices may be installed at the major drainage stnictures and flow concentration points shown on the Drainage Exhibit. Such structures can be used to intercept and trap sediment once it is produced and prevent it from getting Offsite onto downstream property. • 5-1 - rte ,,- ONSITE DRAINAGE CALCULATIONS APPENDIX 5-2 I 'Li VCCD- Zt4o r�EFr 6B3co1- 3o — �•. ,L ISj 1998 D7-AN\ GF CALcuLfR-\\orvs Foti R mr\c_'n *usrrvEsS 0CTE7.

During the review, Chad Morgan, District Wildlife Manager, made a site visit to the parcel. In this letter you will find the Division of Wildlife comments concerning the proposal. It is the Division of Wildlife's recommendation that: • Any prairie dog removal follow the below recommendations. • A survey be done for the presence of Burrowing Owls. • Initial construction occur between August 15 and April 1 to minimize impacts to ground nesting birds. • A weed management plan be developed for during construction and for a period of at least 5 years after construction. The Division of Wildlife is most concerned about the impact of construction to areas with Black-tailed Prairie Dog colonies. The presence of Black-tailed Prairie Dogs gives rise to several potential concerns from an ecological view as well as the public relations/public policy arena. From a biological standpoint, praise dogs may be considered a key species in prairie ecosystems. The National Wildlife Federation has petitioned the U.S, Fish and Wildlife Service (USFWS)to list Black-tailed Prairie Dogs, the species found in Larimer and Weld Counties, as a threatened or endangered species on the federal roster. Currently, in Colorado they are allowed to be taken to alleviate nuisance/damage situations on private property. Prairie dog removal should be required prior to development. Trapping/transplant efforts or euthanasia are legal options for prairie dog removal. Euthanasia efforts must occur through the use of approved toxicants and trapping and transplanting of prairie dogs requires prior approval of the Colorado Division of Wildlife. Note that bulldozing active prairie dog colonies is not an acceptable method of removal. DEPARTMENT OF NATURAL RESOURCES, Harris D. Sherman, Executive Director WILDLIFE COMMISSION, Jeffrey Crawford, Chair•Tom Burke, Vice Chair• Claire O' Neal, Secretary Members, Robert Bray• Brad Coors• Rick Enstrom • Richard Ray•James McAnally• Ken Torres Ex Officio Members, Harris Sherman and John Stulp Burrowing Owls, a species listed on the Colorado Threatened Species List,rely on prairie dog burrows as critical nesting habitat. As a migratory species and a raptor, both the USFWS and the Colorado Division of Wildlife protect Burrowing Owls. The species is considered primarily a summer resident of Colorado and a casual winter resident on the eastern plains of Colorado. In winter, they are found from Texas and New Mexico down into Argentina. The critical nesting period for Burrowing Owls occurs between March 1 and October 31. During this time breeding females occupy burrows, generally in active prairie dog towns, to nest and fledge their young. Nesting owls will return to the same prairie dog town to nest year after year unless the town is destroyed. When confronted with human disturbance near nest sites, Burrowing Owls abandon the nest. Efforts to relocate nesting owls have generally proven to be ineffective. If possible, construction in and around prairie dog colonies should be sequenced to avoid critical nesting periods for Burrowing Owls. If it should be necessary to break ground during the critical nesting periods for Burrowing owls, impacted prairie dog towns should be surveyed for Burrowing Owls by a biologist certified for such work prior to onset of construction. If owls are found to occupy prairie dog towns, the active burrows should be protected as specified by accepted guidelines. The Division of Wildlife can provide specifics upon request. The short grass/weed pasture with the bare ground makes for desirable nesting habitat for many of the ground- nesting birds. Human activities around these nests can have negative impacts on them. It is recommended that any construction that takes place on the site occurs before April 1 and after August 15 to minimize any impacts that human activity may have on these nests. With new construction taking place and machinery being transported from one site to another, it is important to help prevent the spread of noxious weeds. Noxious weeds reduce property value and wildlife habitat. Care should be taken to avoid spreading and introducing noxious weeds. Equipment should be cleaned periodically to remove weed seeds even if no weeds are recognized. The area should be promptly revegetated using native species to prevent erosion and invasions by weeds. It is recommended that a weed management plan be developed for during construction and for a period of at least 5 years after construction has ended. On behalf of the Division of Wildlife I would like to thank you for the opportunity to review and comment on this proposal. If you or the applicant have any questions, please feel free to contact Chad Morgan at 970-356-6528.

Plans did not indicate the Building Code construction type therefore; the specific fire- and life-safety requirements cannot really be determined at this time. However, assuming that the building is of type Il-B or III-B construction and protected with an automatic fire sprinkler system, a minimum fire flow of 2,125 gallons per minute, measured at a residual pressure or 20 pounds per square inch, would be required as per Appendix Ili-A of the Fire Code. This water supply would need to be provided by at least two fire hydrants. The site utility plan did not show any fire hydrants on Kings Court and showed only one fire hydrant located on Camelot Circle. All hydrants used to meet the required water supply shall be within 600 feet of the building as measured along approved fire apparatus access routes around the exterior of the building; and, at least one fire hydrant shall be located such that it is within 450 feet of all portions of the building. • Fire apparatus access to the building appears to be adequate as indicated on the plans. Fire apparatus access roads must be designed and maintained to support the imposed loads of fire apparatus (75,000 pounds). • Building construction plans and a final site plan showing the gross square footage of the building and building construction type must be submitted to the Fire District for review and approval before building permits may be issued. The final set of site plans must include a utility plan showing fire hydrant locations and water main sizes. • A final inspection of the occupancy by a member of the Fire District will be required before a Certificate of Occupancy is issued from Weld County.

A legible project vicinity map shall be included as a figure in the drainage report clearly identifying the borders of the proposed development, bounding roads and properties, water features, north arrow, and approximate scale (Weld County Code Section 27-9-10, I) The Drainage Report references a "Cold Storage Lot 6, Block 1"report in the footer. Please revise the text of the report to reference Lots 7-10. All drainage features (detention ponds, swales, pipes, outlet structures) are to be shown in dedicated drainage easements on the construction plans and Final Plat. Please address all redline comments in the drainage report. The applicant is advised that until the replat of Lot 5 occurs to dedicate easement for the proposed detention pond and pipe, site plan approval and subsequent building permits will the upheld for all development contemplated on Kings Court. The applicant shall discuss the street capacity in WCR 9.5 relative to the emergency overflow volume coming from the detention pond on Lot 5 and how this affects street capacity in a 100-year storm. Please be advised that maximum overtopping depths cannot be exceeded. Please refer to UDFCD standards with Weld County modifications. • Please verify, by showing additional mapping outside the project boundaries, that OS1 and OS2 and O53 are the only contributory offsite sub-basins. Pipe Run A appears to "daylight" into the bottom of Baugh Lateral. Please verify normal operating depth of ditch. It appears as though ditch water will back up into the pipe system. Also please provide a copy of the agreement from the ditch company stating that they will accept stormwater flows from the site and that they approve of the location, size and configuration of the proposed discharge pipe in their ditch. This must be included as an attachment in the drainage report appendix. Please provide rip rap sizing calculations for both energy dissipation/erosion control at pipe outlets as well as the emergency overflow structure of Pond 5. Please identify all existing and proposed utility locations. It is unclear from the information provided if clogging factors were used in inlet sizing calculations. Please provide the necessary calculations. Pipe hydraulic calculations cannot be assessed until an onsite and offsite drainage basin map is provided. When hydrologic calculations can be verified, hydraulic calculations will be reviewed. All riprap must terminate underground per UD&FCD standards published in Chapter 7 figure MD-12. Please add a detail to construction plan documents for this riprap termination.

Rademacher Business Park Final P.U.D i 5/20/2007 Lots 7 to 10 of Block 2 1. Project Location and Description Kings Court Business Complex is a 12.91-acre site located on Lots 7 through 10 of Block 2 of the Amended Plat of the Rademacher Business Park Final P.U.D. which is located in the Northwest Quarter of Section 23 Township 3 North, Range 68 West of the 6t" Principal Meridian, Weld County, Colorado. Lots 7 through 10 are situated south of Weld County Road (WCR) 32 and west of WCR 9 '/. Lots 7 through 10 are arranged around the Kings Court cul-de-sac to the north of Camelot Circle. A vicinity map is included on the following page for reference. This report will address storm drainage from the four lots contiguous to Kings Court. The storm drainage from the developed portions of the four lots will be detained in a common detention pond on Lot 5 Block 2 and released at the Master Planned rate for these lots. Lots 7 and 10 will be developed upon approval of the drainage plan and construction documents. Lots 8 and 9 will be graded and storm sewers extended but will remain undeveloped until these lots are sold. All disturbed areas will be revegetated in the interim. All future development on Lots 8 and 9 of Block 2 will have to comply with this Final Drainage Plan Report. 1.1. Existing Conditions The current conditions of the lots consist of vacant land with light grass and weed cover. The land surface generally drains north away from the Camelot Circle and Kings Court (south of the lots as shown on the Drainage Plan at the back of this report) to the Baugh Lateral irrigation ditch which crosses under Interstate Highway 25 and runs parallel and south of Weld County Road 32 as it drains to the east. The estimated average land surface is 2 to 3 percent. The Soils at the surface consist of a clayey loam material with a moderate erosivity for both wind and water. The Baugh Lateral Irrigation Ditch has been modified under the Rademacher Business Park Master Drainage Plan to increase the capacity of the ditch. This was done to allow the ditch to accept and convey storm drainage runoff from the land to the south as it is developed at the 2-year historic runoff rate per the Landmark Master Drainage Plan. A letter of approval from the Baugh Lateral Ditch Company to accept these flows, dated November 14, 2006, is included in the Appendix. Camelot Circle, forming the southern boundary of lots 7 and 10, and Kings Court separating these two lots, are built on a fill embankment of 2 to 3-feet of native material to this area. The roads consist of a two-lane, urban road with parking. Camelot Circle has curb and gutter on both sides and a high point at the intersection with Kings Court. Storm drainage from Camelot Circle is collected in two type 'R' inlets at the sag curve sump approximately located at the property line between Lots 10 and 11of Block 2 as shown on the Drainage Plan attached to the back of this report. These inlets drain through an 18-inch pipe to a swale that runs north in an easement along the property line between Lots 10 and 11.

Proposed Condition Kings Court Business Complex is proposing to develop Lots 7 through 10 into four office buildings, one on each lot. The development will create approximately 82 percent imperviousness across the four lots. The impervious area includes asphalt parking and proposed buildings. Two new entrances will be developed from Camelot Circle to Lots 7 and 10 which will allow storm drainage to flow directly from the road to Lots 7 and 10. Drainage from Kings Court and the area of Camelot Circle adjacent to Lots 7 and 10 and upstream of the entrances will be collected and conveyed through the site to the new detention pond to be located along the south side of Lot 5 Block 2 along with flows from the developed lots. Following sections will describe the basin in detail. 2. Basis for Design The basis for the storm runoff design was taken from the Master Drainage Plan and Report for Rademacher Business Park P.U.D. (LMMDP) prepared by Landmark Engineering Ltd. For Zeek Properties dated October 1996 and the Weld County Drainage Criteria. 2.1. Master Drainage Plan and Report for Rademacher Business Park P.U.D 2.1.1. Basin Delineation The LMMDP for the Rademacher Business Park P.U.D broke the entire 143-acre site into two sub-basin areas. Basin 1 consisted of those areas south of, and tributary to, the Baugh Lateral Ditch. Basin 2 consisted of the areas north of, and draining away from, the Baugh Lateral Ditch to culverts under Weld County Road 32 and ultimately a regional drainage swale a short distance to the north of WCR 32. Basins 1, draining into the Baugh Lateral ditch drains east to WCR 9 '/z through the improved section of ditch. The Baugh Lateral ditch flows under Interstate Highway 25 in a approximate 10' by 6' concrete box culvert of unknown capacity or tributary area. To the east of the highway, the ditch was improved to provide a capacity of 100 cfs to the east side of WCR 9 % . East of WCR 9 'A , irrigation and storm drainage flows are conveyed a mile east to a sod farm where they are consumed_ It is not clear from the LMMDP if the Baugh channel has a 100-cfs capacity beyond WCR 9 'h. Should there be insufficient capacity in the ditch beyond WCR 9 'A, it is unclear where the excess flow will spill from the ditch. The flows could spill to the west barrow ditch of WCR 9 '/A to be conveyed north to WCR 32 or further east at an unknown low point in the ditch bank beyond a check structure attached to the east end of the box culvert under WCR 9 '/2 . A prominent swale drains northeast from the ditch directly east of Cold Storage Lots 7 to 10, Block 2 3 5/20/07 Rademacher Business Park Final P.U.D WCR 9 'A and to WCR 32. This swale historically accepted approximately 55-acres from the Rademacher Development west of WCR 9 'A which is currently intercepted by the Baugh Lateral. At WCR 32 flows mix with those from Basin 2 (areas north of the Baugh Lateral) and then drain to a eastward trending tributary to Lake Thomas as shown on the Vicinity Map included with the LMMDP included in Appendix B. 2.1.2. Allowable Release Rate Lots 7 through 10 of Block 2 are located in Basin 1 and drain to the Baugh Lateral Ditch as shown on the Drainage Plan. Per the LMMDP this area shall be detained a release at a rate equal to the 2-year historic runoff for the area tributary to the ditch. From the LMMDP, the tributary area to the ditch is 96.7 Acres and the 2-year historic storm run off rate was estimated at 23.0 cubic-feet-per-second (cfs). This equates to an allowable release rate of 0.238 cfs /acre. 2.2. Site Constraints Lots 7 through 10 are constrained by their location separate from the Baugh Lateral Ditch to which they will discharge. The plan for these lots is to drain into a regional detention / water quality pond to be located on Lot 5 of Block 2. The discharge from the pond will be release through Pipe Run A along the existing 20-foot wide drainage easement along the west side of Camelot Circle. Pipe Run A will discharge to the Baugh Lateral above its concrete lining and well above its operating level approximately a foot below the concrete crest. Storm flows from Lots 7 through 10 will be collected in CDOT type 'R sump inlets located throughout the development and conveyed to the pond in Pipe Runs B and C. This configuration is shown on the Drainage Plan. 2.3. Drainage Criteria This drainage evaluation follows the criteria laid out in the Landmark Engineering Master Drainage Report. Hydrology and Hydraulic calculations shown in Appendix A are base on the Weld County Addendum to the Urban Drainage and Flood Control District Criteria (WCSDC). 3. Storm Drainage Design The general concept for the drainage design for Lots 7 through 10 of Block 2 consist of creating Detention Pond 5 along the south property line of Lot 5 as shown on the attached Drainage Exhibit Lot 5 is owned by the developer and will be replated with this effort to dedicate Pond 5 as a drainage easement. This pond will detain storm runoff to the 100-year event and release at the 2-year historic rate (0.238 ds/ac) as dictated in the LMMDP for the areas tributary to the Baugh Lateral Ditch. Detention of the storm flows will be achieved by constricting the outlet pipe to a maximum discharge under the maximum head using an orifice plate. A minimum of one-foot Cold Storage Lots 7 to 10, Block 2 4 5/20/07 Rademacher Business Park Final P.U.D freeboard depth from the 100-year detention pond surface to the top of the berm will be created with the grading of the pond. The pond shall be constructed with an emergency spillway with a hardened concrete cutoff weir section size to spill the 100- year flow into the pond (62 cfs) at a depth of less than 6-inches. The down stream face of the emergency spillway will be protected with angular riprap. Emergency flows greater than the 100-year storage volume will be routed north via Camelot Circle, over the Baugh Lateral Ditch, and to the sump point in Camelot Circle southwest of the lot line of Lots 5 and 6 of Block 1. Emergency flows will then flow northeast along the drainage easement between Lots 5 and 6 of Block 1 through a series of detention ponds on Lot 6, Block 1 and ultimately to WCR 32. From WCR 32, emergency flows will make their way to the swale system draining to Lake Thomas. 3.1. Rational Method Runoff Calculations The rational method was used to estimate the runoff to the proposed detention pond. The composite 'C' values for the areas tributary to Ponds 5 were estimated from areas taken from the proposed plans for the access paving, buildings and detention areas_ The values used in the estimates of detention are summarized and detailed in the calculations in the Appendix A to this report. 3.2. Modified FAA Detention Volume The Denver Urban Drainage and Flood Control District, FAA Detention Volume spreadsheet was used to track the mass balance of the stormwater runoff into and from Detention Pond 5. A print out of the spreadsheet and graph of the mass balance is provided in the Appendix A Based on this analysis, the required detention volume in Pond 5 is: • Pond 5: 126,000 Cubic Feet or approximately 2.833 Acre-feet 3.3. Available Detention Pond Volume The proposed detention pond grading plan was evaluated for volume and found to provide sufficient storage volume for the 100-year storm event at the allowed release rate. The maximum 100-year stage of the pond is estimated to be 4957.00. The top berm elevation will be a minimum of one foot higher than the maximum 100-year water surface. The crest of the emergency spillway will be set at 4957.00 and the crest of the berm at 4958.0 feet. A concrete weir section and rip rap rundown protection will be included at the outfall of the emergency spillway_ The location of the emergency spillway is shown an the Drainage Plan, Sheet 1_ Pond 5 will provide a the required 40-hour Extended Detention water quality capture volume as part of the 2.833 acre-foot storage. The required capture depth is 0.34-inches which equates to a required design volume of 0.47 acre- feet at pond elevation 4952.6. Cold Storage Lots 7 to 10, Block 2 5 5/20/07 Rademacher Business Park Final P.U.D 3.4. Pond 5 Orifice Plate Sizing Standard orifice equations for a sharp plate were used to calculate the necessary opening size at the primary spillway for Pond 5. The calculation was based on the allowable release rate of 3.32 cfs and the maximum 100- year water surface detailed above and solved for the allowable orifice area shown below. The actual calculations are included in Appendix A on the detention spreadsheet. • A rectangular opening 6-inches wide and 6.5-inches high providing 39 square inches at a maximum head of 6.5 feet allowing a maximum 100- year discharge of approximately 3.32 cfs. This plate will be mounted inside the Type C inlet, in front of the opening to Pipe Run A. • The water quality orifice plate will be bolted to the external face of a modified Type C inlet and contain six, 2-inch diameter openings in a single row. These plates are detailed in the construction plans. Should the water quality plate become plugged, the WQCV will fill up to the top of the Type C box and spill through the grate and through the 100-year orifice plate. The water quality plate can then be cleaned with the WQCV has infiltrated. 3.5. Storm Sewer Design Storm sewer pipe runs A through C were modeled using Neo-UD-Sewer Version 1.6.7 dated November 2006. The pipe runs were modeled using standard pipe, bend and lateral losses. The pipes were allowed to pressurize maintaining a minimum 1.0-foot separation between the energy grade line and the rim elevations on all structures. The hydraulic gradeline and energy gradeline are represented on the profiles of each run in their respective projects. Reinforced concrete pipe with pressure rated rubber gaskets are specified for the construction. Storm sewer construction details are taken from City of Loveland standard details which meet Urban Drainage and Flood Control District requirements. 4. Erosion and Sediment Control The Soils at the surface consist of a clayey loam material with a moderate erosivity for both wind and water. The vegetative cover is fair allowing significant soil exposure to erosive forces. During the construction phase the control and practice measures shown on Sheet 2 should be implemented to prevent unnecessary loss of soil from the site. This plan will be used as the basis for a SWMP for the construction site. Permanent erosion controls for Lots 7 and 10 will consist of the buildings, pavements, and landscaping. The landscaping will include sod, gravel areas, bush and trees. Lots 8 and 9 will be reseeded after overlot grading. Cold Storage Lots 7 to 10, Block 2 6 5/20/07 Rademacher Business Park Final PAID Temporary erosion controls shall remain on Lots 8 and 9 until the vegetative cover has reestablished. Storm sewer construction details are taken from City of Loveland standard details which meet Urban Drainage and Flood Control District requirements. 5. References 1.

The development of the recommendations is presented in the following sections of the report. Introduction The Rademacher Business Park P.U.D. is a proposed L i acre business park it Weld Count—. -3'_oradn. The proposed development is located on the East side of Interstate 15 and is bounded on the Mort' I - WeldC'.ounty Road ?? and on the East by Count: Road 9 1/2. Access to the site is from the frontage road situated between I-25 and the or fret site. This Master Drainage Plan and Report covers the general drainage patterns for the overall ,Site, 3-3 and it is proposed that a final drainage study be prepared for each lot as a par of the s p ie, individual development plans. The final drainage study shall address -,t�_il = sit,, drainage 1 patterns and facilities based on the final grading and development plans, and must be in compliance wit la rrquifoments of this Master Drunage Plan and Weld Goo rte: Criteria. The purpose or this i"Master Drainage Study is to provide general drainage planning for the , vend]r development. This his includes identifying and defining conceptual solutions to drainage problems which ntav occur onsite and offsite as a result of this development, and identifying nage structures and other drainage features which should be included in the de':eiooment plans to provide a complete, safe and economical drainage scstem design. A 'undamenta l chic Live of this drainage studs' is to develop a visionary drainage plan that can be understood and adopted and can be implemented ented and controlled effectively. This Drainage Study evaluates the existing drainage patterns of the site and identifies future drainage patterns for the development based on the project layout, the grading plan, and other existing sire constraints. This includes evaluating historical runoff, investigating routing for design storms through the development, determining what improvements and strictures are rec,tsar: along with required design caparity, and evaluating offsite drainage which may affect or be affected by the development. The polio: and guidelines outlined in the Weld County Subdivision Regulations and technical data from the Larimer County Storm Water Management Manual have been utilized for planning drainage facilities. A ,naior storm drainage system and a minor storm drainage �l have t ee planned as shown on the Master Drainage Plan. The major storm drainage syst r has been designed CO convey runoff from a 100-Year storm through the development T ... a manner- which minimizes health and life hazards, damage to structures and interruction c f;rc and -erg;iC:'s The ha minor storm drainage system has been designed to ccnvey runoff 1-1 from a 2-Year storm, and/or nuisance flows, through the development with a minimum disruption to the urban environment. Findings. Conclusions and Recommendations 1, which arise this principal findings, conclusions and recommendations out of Drainage Study are presented below. These finding_ are supported by the detailed material presented nted in the body of the report. Cffsite Drainage and Existing Drainaye_Pattern_ Offsit: arm—taxi: tributary to the project site consists of storm runoff from the Iti2cC Motors property which is located adjacent to the Southwest corner of the site, and runoff from approximately 15 acres situated adiacent to the South boundary of the site. Currently storm runoff from these two offsite areas and from about 96.7 acres of onsite area, drains in a Northeasterly direction following existing surface drainage patterns to the Baugh Lateral Ditch. The Baugh Lateral l Ditch meanders across the site fro a point near the Northwest corner to approximately the * sidpomt of the East bounded— :, line. Based on calculations presented in the anpernii6 rho two year historical release rate for the 96.7 acres of onsite area which drains into the Baugh Lateral Ditch is 23.0 CFS or 233 CFS/AC. As can be seen on the Master Drainage Plan, it is proposed that a swale be constructed along the South boundary line to divert drainage from the area South of the site East to the Roadside Ditch for County Road 9 1/2. This storm ^" runoff could then now North to the Baugh Lateral Ditch_ The storm water release from kLC Motors has been routed through the site to discharge points into the Baugh Lateral Ditch. It is proposed that each individual lot be required to detain storm runoff and release it to discharge points at a rate not more than the historical 2 Year flow rate. S Currently, there are two (2) storm water discharge points for the site area that is North of the Baugh Lateral Ditch. As can be seen on the Master Drainage Plan, there is a 12" CMP which crosses County Road 32 at a point along the North boundary of Lot 6, Block 1. The tributary- area for this culvert is Lots 4-7, Block 1. It is proposed that as these lots develop, they be required to limit storm water runoff to a pro rated share of the capacity of the 12" CMP. Based on calculations shown in the appendix, this establishes an allowable release rate of 0.2055 CES/ acre. There is also a 12" CMP which crosses County Road 32 at a point near the Northeast corner of Lot 2, Block 1. The tributary area for this culvert is Lots 1-3, Block 1. It _ is proposed that as these lots develop, they be required to limit storm water runoff to a prorated share of the capacity of the 12" CMP. Based on calculations shown in the appendix, this establishes an Allowable Release Rate of 0 23 CFS/acre. is 1-2 __ 2) Baugh Lateral Ditch I As can be seen on the Master Drainage Plan, the Baugh Lateral Ditch meanders across the project site from the Northwest corner to approximately the midpoint on the East boundary line. It is proposed that a concrete liner be installed in this ditch and that 1 it be re-aligned to be within an 80 foot wide easement as shown on the subdivision plat. The ditch has historically intercepted storm runoff from about 97 acres of the project site area and storm runoff from any tributary offsite area. Because this ditch 1 has historically accepted storm ruboff from the project site, and based on conversations with representatives the Ditch Company, it is proposed that onsite detention be required to limit the discharge into the ditch to not more than the historical 2 year 1 peak flow rate for the onsitc area. Drainage structures have been planned and designed as shown on the Master Drainage Plan to control the flow and discharge points into the ditch. Based on calculations shown in the appendix, the historical 2 year peak flow rate for the onsite area is 23 CFS or 0.238 CPS/acre. It is proposed that as each individual lot develops, it be required to submit a drainage plan to the Ditch Company I and Weld County for approval. This Drainage Plan must detail the detention requirements based on a storm water release rate of 0.238 CFS/acre for a 100 year storm and the proposed individual site development plans. The allowable Release Rate Ifor each lot is shown on the Master Drainage Plan. Based on conversations with representatives from the Ditch Company, the new ditch T section has been designed to have as a minimum, the same capacity as the existing ditch 1 section. Based on existing topographic and a typical cross-section, the existing ditch has capacity for about 100 CPS at bank full conditions. The proposed ditch section is I concrete lined for a depth of 2 feet. The concrete liner has a bottom width of 4 feet and 1.25 to 1 side slopes. The top 2 1/2 feet of ditch section is grass lined and has been designed with 4:1 side slopes. The total capacity of the proposed ditch section is about I123 CFS at bank full conditions. The ditch crossings and culverts have been designed i with minimum capacity of 100 CFS. 1 . 3) Detention Facilities IThe allowable release rate for each individual lot has been shown on the Master Drainage Plan. The approximate storm water detention volumes for each lot have also been indicated and are based.on a site runoff coefficient of 0.75. The final runoff coefficients may vary depending on final individual site conditions, therefore, the final detention volumes may vary slightly from those indicated on the Master Drainage Plan. The final detention volumes for each site must be determined as a part of final site design for each site. I ... 1-3 1_ 1 4) Onsite Storm Drainage System IThe onsite storm drainage system consists of roadside swales which drain to discharge points into the Baugh Lateral Ditch and to existing drainage crossings at County Road 32. These swales have been designed with minimum capacity for proposed release rates from the tributary onsite area with an allowance for existing flows from the tributar,- offsite areas. The required drainage structures, such as swales, street crossings, storm drains and drainage ways should be constructed along with the streets and overlot grading. The developers of individual lots will then be required to route storm water to these design points by approved methods compatible with the grading and development plan, Weld County drainage criteria and other requirements presented in this report 5) Erosion and Sediment Control Plan The following describes the proposed measures for controlling Onsite erosion and sedimentation onto downstream property, during construction. It is proposed that soil exposure be kept at a minimum during overlot grading and straw bale dikes, silt fences and/or sediment ponds where practical be used to filter storm water prior to discharge into the existing downstream drainage facilities. The final details of the erosion control plan should be included in the final construction plans and in the Final Drainage Report for each individual site development plans. 14 1 SECTION 2 PROJECT DESCRIPTION This project description defines the limits and general topography of the study area and provides a description of the proposed development. Location and Project Description The study area for this drainage evaluation is the area within the boundary of Rademacher Business Park PUD, and the surrounding areas which drain to the site. The site is located on the East side of Interstate 25 and is bounded on the North by Weld County Road 32, on the east by Weld County Road 9 1/2, and on the South by Sekich Subdivision. The project site is located in the NW 1/4 of Section 23, Township 3 North, Range ES West of the 6th P.M., in Weld County. Access to the site is from the existing frontage road along the East side of Interstate 25. h The proposed business park consists of 26 lots averaging about 5 1/2 acres/lot and includes the construction of streets and necessary utilities to serve the development. The topography of the site generally slopes from Southwest to Northeast at about 2% and historical drainage for the pan of the site is by sheet flow into the Baugh Lateral Ditch which is situated across the Northern part of the proposed development. The remaining site area drains Northeast to existing drainage crossings at Weld County Road 32. A master grading and drainage plan has been developed and has been used as a basis for drainage planning within the development. Proposed construction included the re-alignment of the Baugh Lateral Ditch and the installation of a concrete lining in the ditch. Several street crossings and storm water discharge points are proposed as a part of the design for the new ditch. 2-1 1O "' , )- Ir -=,_� .••n ILI � A�1n it - r '\ �� _', ,. /7i II ,.IA\ �I�- I �_� I Lahr.

I SECTION 3 DRAINAGE DESIGN CRITERIA This development of drainage design criteria establishes the methods, procedures and guidelines used to perform the drainage analysis and develop the drainage plan. Criteria Reference The policy and o sidelines outlined in the Weld County Subdivision Regulations along with .3, technical data from the Larimer County Storm Water Management Manual have been utilized for planning drainage facilities for The Rademacher Business Park. Two separate drainage systems have been planned and designed for this development. The minor drainage system has been designed to convey runoff from a 2-Year storm utilizing storm drains and the street cross- H sections within acceptable depth criteria. The major drainage system is designed to convey runoff from the 100-Year storm utilizing the minor storm drainage structures and the street , section within acceptable depth criteria. Design Storms Based on information in the Precipitation-Frequency Atlas of the Western United States, Volume III the storm isopluvials between Denver and Loveland generally follow Interstate 25. Therefore the tabulated design storms for the City of Loveland have been used as a basis for drainage planning within this development. For this project, a minor storm is identified as a 2 hour design storm with a recurrence interval of 2 years and a total rainfall depth of 1.18 inches. A major storm has a recurrence interval of 100 years and a total rainfall depth of 3.01 inches for a 2 hour storm. These storms have been used as a basis for planning and system design. The peak flow rates for design points have been calculated based on the rational method with a storm duration set equal to the time of concentration for each sub-basin. Detention Ponds The proposed detention ponds have been sized based on the Modified Rational Method for -a determining detention pond volume requirements. The Modified Rational Method develops a family of hydrographs based on the peak flow rates for rainfall intensity averaging periods. The proposed maximum release rate from the detention pond is then superimposed on the hvdrograplis and the required detention storage for each hvdrograph is approximated as the area beneath the hvdrograph and above the proposed maximum release rate. 3-1 m Y This procedure slightly under estimates the required storage volume because the actual release is a curvilinear outflow hydrograph. However, because the release rate is small compared to the peak discharge of the inflow hydrograph, the resulting volume error is small compared to the volume of storage required. Swale Capacity_ The primary function of the swale system is to provide an emergency passageway for major flood flows and Offsite flows with minimal damage to adjacent property. The capacity of the proposed swale sections has been evaluated based on uniform flow as determined by the Mannings Formula which is presented below: Q = (1.49/N)ARv'S,;≥ Where Q = Discharge in CFS _ N = Roughness Coefficiency (.035 for grass) A Area in Square Feet r11 Hydraulic Radius (A/P) Wetted Perimeter S = Slope of Energy Grade Line t. as 71 3-2 aJ SECTION 4 DRAINAGE FACILITY DESIGN This section describes the drainage facilities shown on the Drainage Exhibit and explains how storm water will be routed through the development. General Concept The master drainage plan for Rademacher Business Park is to require individual site detention with a 2 year historical release rate. Existing drainage patterns and discharge points are maintained where practical. The Baugh Lateral Ditch effectively divides the site into two (2) separate drainage basins which are discussed separately as follows: Area south of Baugh Lateral Ditch There are about 96.7 acres lying South of the Baugh Lateral Ditch which have historically followed existing surface drainage patterns draining into the ditch. It is proposed that a concrete liner be installed in the ditch and that the ditch be re-aligned -'' to be within a new SO foot wide easement as shown on the subdivision plat and on the Master Drainage Plan. Storm water discharge points may be constructed at various points along the ditch to accept runoff from the area south of the ditch. It is proposed that each individual site be required to detain storm water and release it to proposed drainage ways at a controlled rate equal to the historical 2 year peak flow. The Master Drainage Plan has identified release rates and approximate detention volumes for each lot. The detention volumes have been calculated using a runoff coefficient of 0.75. These volumes may vary- depending on the details of each site plan: however, the release rate should not exceed those values shown on the Master Drainage Plan. Area north of Baugh Lateral Ditch There are about 38 acres north of the Baugh Lateral Ditch that drain to two (2) separate culverts which cross County Road 32. As can be seen on the Master Drainage Plan, Lots 1-3, Block 1 drain to one 12" CMP located near the northeast corner of lot 2, the total tributary area to this discharge point is about 15.9 acres. The prorated release rates and approximate individual site detention volumes for each lot have been shown on the Master Drainage Plan. It is proposed that each lot be required to control the storm water release rate to not more than the values shown on the Master Drainage plan. 3-3 Lots 4-7, Block 1 currently drain to a 12" CMP located along the North boundary of Lot 6. The total tributary area to this discharge point is about 21.9 acres and prorated release rates and approximate individual site detention volumes for each lot have been shown on the Master Drainage Plan. 1 71 1 'tl cr i {`1 "L^ 3-4 SECTION 5 EROSION AND SEDIMENT CONTROL This section describes methods which are recommended to control wind erosion, water erosion and sediment during and after the construction of drainage structures, and site grading. 1 Discussion The clearing and stripping of land for site grading, overlot grading, or for the construction of drainage structures, and swales, may cause high localized erosion rates with subsequent deposition and damage to Offsite properties. Uncontrolled, such erosion could destroy the aesthetic and practical values of individual lots, and cause damage to downstream property. In general, the erosion and sediment control measures may consist of minimizing soil exposure, controlled runoff across exposed areas, and sediment control at drainage structures. Each of these measures is described below and should be utilized by individual lot owners as well as the developer during any construction activity which occurs at this site. General Erosion and Sediment Control Measures Minimizing Soil Exposure: Where practical, the construction area and duration of soil exposure should be kept to a minimum. All other areas should have a good cover of vegetation or mulch. Grading should be completed as soon as possible after it is begun. A temporary cover crop, a permanent vegetative cover crop, or other landscaping should be established in the disturbed areas. Revegetation may consist of native grasses, lawn grasses, or various winter wheat. Decorative rock, flower gardens, or shrubs may also be utilized in the final landscaping to cover the soil. Reseeded areas should be mulched with straw or hay to protect exposed soil until vegetation is established. Controlled Runoff Across Exposed Areas: Where practical, construction may include constructing temporary swales to intercept and direct storm water around exposed areas. Swales can be constructed to control surface water which collects on exposed areas and prevent gross erosion in the form of gullies. Riprap or other temporary erosion control devices may • be installed to control storm water velocities across exposed areas. Sediment Control: Temporary and/or permanent sediment control devices may be installed at the major drainage structures and flow concentration points shown on the Drainage Exhibit. Such structures can be used to intercept and trap sediment once it is produced and prevent it from getting Offsite onto downstream property. 5-1 I ' ONSITE DRAINAGE CALCULATIONS N 4+ i • APPENDIX I 6 _. 5-2 Iael P o F� R?z5L IS, 1996 \N {N\GE CP.LCvLP.7\o1vS F-c•R ?POr;:• M \c.`1ECZ I .
