Plans did not indicate the Building Code construction type, therefore, the specific fire- and life-safety requirements can not really be determined at this time. However, assuming that the building is of type II-B or III-B construction and protected with an automatic fire sprinkler system, a minimum fire flow of 2,000 gallons per minute, measured at a residual pressure or 20 pounds per square inch, would be required as per Appendix III-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 the location of existing or proposed fire hydrants, or the location of the underground fire line. 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. Additionally, plan sheet 9 of 9 (Utility Details) shows a Residential 1-inch fire sprinkler meter.

Comments made during this phase of the process may not be all-inclusive, as other concerns or issues may arise during the remaining application process. Comments The applicant is proposing a 34-35,000 square foot industrial/commercial building on Lot 7, Block 2 of the Rademacher Business Park. The applicant states that 70 employees will use the site and 183 parking spaces will be provided. The applicant submitted a Change of Zone Drainage Report for Kings Court (Lots 7— 10), Site Plan Review Application materials and construction plans titled Lot 7, Block 2, Commercial/Industrial/Retail/Office Facility sheets 1-9. REQUIREMENTS: General: Please note that all reports and construction plans completed by a Colorado Registered Professional Engineer must be signed and wet stamped for Final acceptance by Weld County. The application materials refer to a "sand filter" to be used for water quality purposes. However the construction drawings do not include any details as to the type and location of said filter. Please provide detail drawings. Please add a note to the drawings stating that the operation and maintenance of the sand filter are the responsibility of the property . owner. Access: The applicant is proposing three access points to the site. Two accesses will be from Kings Court and the third from Camelot Circle. It is noted that the south access on Kings Court is aligned with the access of Lot 10, Block 2. The grades, widths and radii of the accesses meet code requirements. It is also noted that the north access on Kings Court is designed to straddle the property line. As such, this access can also serve Lot 8. Please provide and show on the plans a joint access easement across the northern access beneficial to both Lots 7 and 8 on the final plat. Parking: As noted on the construction plans, all off-street parking shall be paved according to the design provided with the construction plans. The applicant is advised that the minimum pavement section allowed is 4-inches HMA (Grade C or CX) over 6-inches Class 5 or 6 aggregate base course (23-3-350,Table 23.7). All site grading and paving shall be done according to the approved grading plan. EmployeeNisitor parking shall be identified and shown on the Final Plat drawing. Equipment parking shall also be identified and located on the Final Plat drawing. All parking spaces must be labeled showing general location, arrangement and dimensions of parking spaces, width of aisles, width of bays, angle of parking and other similar information. The parking lot design must meet current ADA requirements. It is anticipated that as many as seven (7) ADA accessible spaces will need to be provided. The Public Works Department requires all parking lot striping to identify the ADA space(s)with the appropriate symbols and signs conforming to MUTCD or other signing standards. The applicant has proposed 20 parking spaces constructed perpendicular to Kings Court within public Right Of Way. This proposed parking will not be allowed. All parking that serves Lot 7 shall be constructed on Lot 7 per (23-4-20, A). Please modify the design drawings accordingly. SPR-409 Zeek Partnership-DTBcomrnnts.doc Page 1 of 2 January 15,2007 • Circulation: Circulation throughout the site appears adequate. A minimum of a 20' clear zone throughout the site must be present to accommodate emergency vehicles. The applicant shall provide an explanation as to the size and type of vehicles that will use the loading area and describe how this use might affect circulation. Utilities: The applicant shall show all utility and drainage easements on the Final Plat. Sanitary Sewer Service: Section 27-2-176 of the Weld County Code specifies that Subdivisions provide sanitary sewer service. The Rademacher Business Park and this parcel appear to be served by sanitary sewer (St. Vrain Sanitation District). Construction drawings show sewer lines in both Kings Court and Camelot Circle. The applicant is requested to explain why this application proposes to use a septic leach field when this parcel is served by sanitary sewer. Storm Water Drainage: Please add the following note to the text of the Final Drainage Report, Construction Drawings and Final Plat: "Weld County will not be responsible for the maintenance of drainage related structures and areas." 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 I"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 add SPR 409 to all construction drawings and reports connected to this application. Please address all redline comments in the construction plan drawings. 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 OS I and OS2 are the only contributory offsite sub-basins. The applicant discusses detention pond volumes in part 3.1 referring to both ponds 5 and 6. Lot 6 detention is provided directly south of Lot 5. Is the text in the drainage report correct? If so, the applicant shall further provide operational characteristics of both ponds to ensure that adequate capacity exists and they do not adversely affect one another. The detention structure shown in the construction plans is labeled "Pond 6". This structure does not appear to be applicable as the orifice plate is not sized appropriately for the design discharge. Please modify the plans to match the text of the report. 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 an 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. 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. SPR-409 Zeek Partnership-DTBcommnts.doc Page 2 of 2 January 15,2007 The construction plan set includes city of Loveland details. These details may be applicable but are not recognized as Weld County standards. Please address how they meet UDFCD and Weld County standards. 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. It is unclear from the information provided if the pipe runs were analyzed using methods that account for tailwater conditions, inlet and outlet control, and other considerations not covered in a normal depth analysis. Please provide the necessary calculations.

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,prairie 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 Latimer 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 0' 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.

Best regards, Char From: David Bauer Sent: Thursday, January 18, 2007 3:36 PM To: Charlotte Davis Cc: Brian Varrella; Jacqueline Hatch; Jesse Hein Subject: Zeek partnership Ted Drysdale called regarding SPR-409. For sanitary service they proposed individual septics for this lot and others in the business park. In our comments we questioned that. He said that the property lies within the Mead sanitary district but they are 3 miles from a line, they are less than 1 mile from a St. Vrain line but Mead won't let them loose from joining Mead's system. Are we okay with septic systems rather than a hook up to the line? Either way they propose not having to build a connection. If not this one SPR, what about the whole subdivision? Should we maybe have them stub out a pipe so that they could, in the future, connect?? Also, they are proposing to re-configure the drainage and have it all go to a single larger detention pond, so expect a new drainage report soon. This will alter options for the other properties and new plats will likely be needed for all since swales and the smaller individual ponds will not be created and so those easements won't be needed.

Chad • Original Message From: Jacqueline Hatch [mailto:jhatch@co.weld.co.us] Sent: Tuesday, March 13, 2007 8:36 AM To: Morgan, Chad Subject: SPR-409 Chad, I just wanted to make sure I understood your phone message the other day regarding Site Plan Review 409. It is my understanding that as long as the applicant removes of the prairie dogs humanly and there are no burrowing owls on site they can begin construction. In a letter from the Division of Wildlife dated February 13, 2007 it states that the black tailed prairie dog inhabits portions of the property. Because prairie dogs inhabit the site removal of the animals need to take place prior to development or construction. The applicant has stated that they will remove the prairie dogs prior to construction. The letter from the Division of Wildlife also states that western burrowing owls may also be living in the prairie dog holes and if construction is to occur between March 1 and October 31 the area should be checked out for owls. The site consists of approximately 2.9 acres. The applicant has also stated that they have not seen any burrowing owls on site. I will ask the applicant to put in writing their procedure for removal of the prairie dogs and that they have not seen any burrowing owls on site. Do you feel the concerns/requirements of the Division of Wildlife have been satisfied?

DIVISION OF WILDLIFE AN EQUAL OPPORTUNITY EMPLOYER 3, - � Bruce McCloskey,Director tab irtiO 6060 Broadway OF Denver,Colorado 80216 Telephone:(303)297-1192 For Wildlife- wildlife.state.co.us For People February 13, 2007 Jacqueline Hatch Weld County Planner Weld County Planning Department 4209 CR 24.5 Longmont, CO 80504 RE: Case Number SPR-409 Dear Jacqueline, I received and reviewed the proposal for the development proposal in the Rademacher Business Park. 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,prairie 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•Ridc Enstrom•Richard Ray•James McAnally•Ken Torres Ex Officio Members,Hams Sherman and John Stulp T 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. Sincerely, dVi' 6'tiad 1VOrC/0�'bt.

BriaWla,P.E., Public Works Depat fluentnt D COLORADO SUBJECT: SPR-409 Zeek Partnership 2 Weld County Public Works Department has reviewed this Site Plan Review request. Comments made during this phase of the process may not be all-inclusive, as other concerns or issues may arise during the remaining application process. Comments This memorandum is a follow up to comments from the Weld County Public Works Department dated January 15, 2007. The applicant resubmitted a revised set of construction plans titled Lot 7, Block 2, Commercial/Industrial/Retail/Office Facility sheets 1-9. REQUIREMENTS: General: Please note that all reports and construction plans completed by a Colorado Registered Professional Engineer must be signed and wet stamped for Final acceptance by Weld County. Please provide a full set of construction drawings showing grading, drainage, site improvements, utilities and details associated with the project. Further review of this application will not continue until these drawings are submitted. Access: The applicant is proposing three access points to the site. Two accesses will be from Kings Court and the third from Camelot Circle. It is noted that the south access on Kings Court is aligned with the access of Lot 10, Block 2. The grades, widths and radii of the accesses meet code requirements. It is also noted that the north access on Kings Court is designed to straddle the property line. As such, this access can also serve Lot 8. Please provide and show on the plans a joint access easement across the northern access beneficial to both Lots 7 and 8 on the final plat. The access flairs to the site are shown to have a typical radius of 30'. All access points to the site shall be amended to have a 40 foot radius per County Code 23-2-160 R 6. Parking: The construction plans have been updated to show an appropriate cross section for the pavement detail. All site grading and paving shall be done according to the approved grading plan. The internal parking and circulation comments have been addressed and are acceptable to Public Works. Utilities: The applicant shall show all utility and drainage easements on the Final Plat. Sanitary Sewer Service: Section 27-2-176 of the Weld County Code specifies that Subdivisions provide sanitary sewer service. The Rademacher Business Park and this parcel appear to be served by sanitary sewer (St. Vrain Sanitation District). Construction drawings show sewer lines in both Kings Court and Camelot Circle. The applicant is requested to explain why this application proposes to use a septic leach field when this parcel is served by sanitary sewer. Storm Water Drainage: Please add the following note to the text of the Final Drainage Report, Construction Drawings and Final Plat: "Weld County will not be responsible for the maintenance of drainage related structures and areas." A legible project vicinity map shall be included as a figure in the drainage report clearly identifying the borders of the SPR-409 Zeck Partnership 2.doc Page 1 of 2 April 20,2007 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 OS3 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. Recommendation ❑ The Public Works Department will continue the review process for this site plan once we receive the requested submittal materials and revised report and drawings.

Mr. Drysdale is proposing minor change to the drainage swale at Cold Storage (SPR-397) to improve safety in the business park. These changes are based on Public Works recommendations, and will not change the drainage patterns or total detention volumes at Cold Storage. They will provide safe conveyance of onsite flows at SPR-408 and 409 to areas inside the business park. This will reduce overall impacts to onsite transportation corridors, and offsite roadways (specifically WCR 9'/Z, and adjacent private properties). We believe Mr. Drysdale's new drainage plan will perform better than his previous plans, with minor revisions to the Cold Storage site. If you have questions, please let me know. Otherwise, have a good day.

Rademacher Business Park Final P.U.D i 5/20/2007 Lots 7to10ofBlock2 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. Lots 7 through 10 are 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 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 llof 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 BusMess 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 '/ 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'A . 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 34, it is unclear where the excess flow will spill from the ditch. The flows could spill to the west barrow ditch of WCR 9 %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 wider WCR 9 'h . 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 I 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 afoot 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 cfs/ac) as dictated in the LMMDP for the areas tributary to the Baugh Lateral DBch. 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 ultirmtely to WCR 32. From WCR 32, emergency flows will make their way to the male 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. April out of the spreadsheet and graph of the mass balance is provided in the Appends( 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 vokane and found to provide sufficient storage vokane 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 toot higher than the maximum 100-year water surface. The crest of the emergency spillway wil be set at 4957.00 and the crest of the bemi 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. Pond 5 will provide a the required 40-noun 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 volumed 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 P.U.D 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 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. ei 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 be in compliance with requirements of this Master Drainage Plan and Weld County Criteria. 1 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 runoff 1-1 from a 2-Year storm, and/or nuisance flows, through the development with a minimum disruption to the urban environment. I Findings, Conclusions and Recommendations I — 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. I_ 1) Offsite Drainage and Existing Drainage Patterns. I Offsite drainage tributary to the project site consists of storm runoff from the K&C 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 Iof 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, tins establishes an Allowable Release Rate of 0.283 CFS/acre. 1 iL 1-2 1 — 2) Baugh Lateral Ditch 1 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 SO 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 t 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 — 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 CFS or 0.233 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. I 1-3 L 4) 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 flews 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 — 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. ( 1-4 L _ 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 tw 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., 1 in Weld County. Access to the site is from the existing frontage road along the East side of Interstate 25. 5 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.

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- - 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. P�. Design Storms Based on information in the Precipitation-Frequency Atlas of the Western United States, L.1 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 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 _�r P ra 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. ISwale Capacity 1 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: 4o-- Q = (1.49/N)ARv3Svz q Where Q = Discharge in CFS �.- N - Roughness Coefficiency (.035 for grass) A = Area in Square Feet r R = Hydraulic Radius (A/P) P- = Wetted Perimeter S = Slope of Energy Grade Line .h 1- if— 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 7 maintained where practical. L 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 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 be required to control the storm water release rate to not more than the values shown on the Master Drainage plan. 3-3 L 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. ,r rte ?9 `•1 3�7 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. 1 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 mollies. 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 1 ONSITE DRAINAGE CALCULATIONS 3 I 4_ 1_ 1_ I i I I APPENDIX I f I- I _ I - I - I- I - 5-2 pjZOSFcT tco Y—`EET--61a3c1- 3c Pp- f-,712-* IS, 191 ��Zt� \rvt GE C \LcuLR\\orvs Foti 7.11\ mr\c`1E2 *us\rvESS N\Vf-- I .
