February 2001 Banks and Gesso, LLC 4.0 Supporting Documents 4.1 Colorado Mined Land Reclamation Board Submittal (A copy of this separate document can be found in Appendix E of this Application package.) 4.2 Plans for Water and Sewer Domestic water will be supplied to the operation by the Little Thompson Water District. Water demand for operations (i.e., concrete batching, dust control, etc.) will be met by using groundwater exposed by mining. Augmentation water (required by the Colorado Division of Water Resources as part of the Temporary Substitute Supply Plan) will be supplied through a lease that the Applicant has with the Town of Loveland, Colorado (makes 200-acre feet of water available annually, in perpetuity). Proof of this water supply can be found in Appendix F. Sewer service for office and crew personnel will be supplied by an engineered septic system. Portable toilets may also be used for field personnel. Prior to commencement of mining activities, a Septic Permit application will be submitted to the County Department of Public Health and Environment. 4.3 Noise Report Noise sources at the site are the concrete plant, the sand and gravel plant, mining equipment, mixer trucks, and other vehicles/equipment related to the operation of the facility. The operator proposes to meet Colorado noise standards for an industrial property of this nature (i.e., 75 dBA daytime and 70 dBA nighttime). Most of the noise sources are setback from the property line by a significant distance. Residential receptors are few, with the closest being approximately 1000 feet from the nearest noise source. 4.4 Soils Report The Soils, Wetlands, and Floodplain Map contained in this application presents the SCS soils data for the property. Green/CroissantSandAndGravelMineAndReadyMixConcretePlant 20023 Loveland Ready Mix Concrete,Inc. 4 March 2001 Banks and Gesso, LLC 5.0 Operating Policies In addition to the commitments contained in the Application to the Colorado Division of Minerals and Geology, the Applicant commits to the following operating policies: 5.1 Setbacks The mining limit will be setback a minimum of 25 ft. from all property lines and 35 feet from WCR 13 and WCR 54 right-of-way lines, pending agreements with owners of permanent man-made structures, as outlined in the requirements of the Colorado Division of Minerals and Geology. Several structures exist on the property, consisting of gas and oil pipelines, pumps, and storage tanks. Agreements are approved or are being developed between the owners of these facilities and the applicant to allow for their continued use and performance while allowing for the mining to occur. A more detailed description is contained within Exhibit D of the Colorado Mined Land Reclamation Board (CMLRB) Application, found in Appendix E of this Application. There are also various permanent man-made structures within 200 ft. of the property lines along the north and west. These structures are shown on Exhibit C and listed in Exhibit S of the Colorado Mined Land Reclamation Board (CMLRB) Application. The State requires setbacks from these man-made structures of 200 feet unless the applicant obtains an agreement with the owner to mine within this distance. The applicant also has the option of supplying an engineer's report stating that mining closer than 200 feet will not affect the stability of the structure. 5.2 Hours of Operation The following hours are proposed for 6 days per week, Monday through Saturday: 7:00 a.m. to 7:00 p.m. for sand and gravel mining and processing 6:00 a.m. to 5:00 p.m. for concrete batching 7:00 a.m. to 7:00 p.m. for truck hauling to and from the site 6:00 a.m. to 12:00 midnight for maintenance and repairs Green/CroissantSandAndGravelMineAndReadyMixConcretePlant 20023 Loveland Ready Mix Concrete,Inc. 5 March 2001 Banks and Gesso, LLC The operations office may operate 12 hours per day, 7 days per week. An exception to the above hours will be allowed when government contracts are obtained that require extended hours. In this case, 24 hour per day operations will be allowed to meet such contract requirements. 5.3 Weed Control Plan The applicant shall cut or trim unsightly and noxious weeds as necessary to preserve a reasonably neat appearance and to prevent seeding on adjoining properties. 5.4 Existing Trees and Ground Cover There are some existing trees on the project site and the ground cover consists entirely of hay fields and pasture. Some non-cropland ground cover that is within the setbacks may remain undisturbed during the life of the project. Existing hay and grass cover not within the setbacks shall be removed due to mining and will be replaced with a native grass seed-mix around the reclaimed reservoirs as per the reclamation plan. 5.5 Access Access to and from the operation onto Weld County Road 13 will use an entrance at the northwest corner of the property, near the intersection of WCR 13 and WCR 54. 5.6 Paving of Access Road The entrance approach to the property will be paved with a typical asphalt apron from Weld County Road 13. The on-site access road from the apron to the processing plant will be chemically treated to control dust when needed. The designated haul route to the site is Weld County Road 54 with 66% of the traffic routed towards the west and 33% hauling towards the east. Upon county approval of this project, the applicant will initiate an agreement to be made with the Weld County Public Works Dept. for improvements and/or maintenance of this section of County Road 13, based upon impacts to the roadway from truck traffic. Green/CroissantSandAndGravelMineAndReadyMixConcretePlant 20023 Loveland Ready Mix Concrete, Inc. 6 March 2001 Banks and Gesso, LLC 5.7 Fencing There is an existing three-strand barbed-wire fence along the perimeter of the property. This fence will be maintained around the entire perimeter of the property throughout the life of the mine. Entrance to the operation from County Road 13 will be gated and locked during non-operational periods. 5.8 Topsoil Salvage As per the reclamation plan in the CMLRB application, there is more than adequate topsoil on site to reclaim the site upon completion of mining activities. The topsoil that will be salvaged for reclamation will be placed along the property boundaries and at convenient locations at the edges of the mine phases. Adequate seeding will be performed to prevent wind and water erosion of the stockpiles. Two topsoil berms will be created and maintained for the life of the mine to act as a visual and noise barrier for neighboring properties. One berm will be located along the western boundary of the plant site to screen the site from Weld County Road 13. A second berm will be placed within the plant site in order to screen the plant facilities from Weld County Road 54. 5.9 Processing Equipment The final plant site area, where the processing equipment and concrete batching is to be located, will be located at existing grade in the northwest corner of the site for the life of the operation. This location is nearest the access point to the site and will thus minimize fugitive dust emission impacts. 5.10 Proof of Insurance Prior to beginning mining operations, and as required by Section 44.4.10, the Applicant will supply the County with proof of insurance against liability for any negligent act or omission by the Operator resulting from the operation or maintenance of the sand and gravel pit. 5.11 Additional Operating Policies 1.

September 28, 2000 Mr.Tug Martin Banks 8s Gesso, LW 720 Kipling Street, Suite 117 Lakewood, CO 80215 Re: Green Property Gravel Pit Weld County, Colorado (LSC # 000940) Dear Tug: We are pleased to submit our report of the traffic impacts of the proposed Green Property Gravel Pit in Weld County, Colorado. This study first provides a summary of existing traffic conditions in the vicinity of the proposed site. It then provides estimates of the amount and directional distribution of traffic that will be generated by the proposed operation as well as estimates of existing plus project-generated traffic volumes on the surrounding road system. In light of the 15 year life of the operation,estimates of Year 2015 background and total traffic are also provided. Finally, the impacts of the project's generated traffic are evaluated and recommendations are made regarding roadway improvements. Site Location and Proposed Use The project site is proposed to be about 160 acres in size. The site is located about three miles northwest of the Town of Johnstown, Colorado,on the southeast corner of the intersection of Weld County Road(WCR) 54 and WCR 13. All access is planned at a single access point onto WCR 13 about 420 feet south of WCR 54. Proposed uses include gravel mining, aggregate production, and storage of aggregate materials. Existing Roadway Characteristics Figure 1,enclosed,illustrates the site location relative to the nearby roadway system.Figure 2 illustrates the existing lane geometry and traffic control at the intersections of WCR 54 with WCR 13 and WCR 17. WCR 54 is a paved, two-lane, east/west county highway running through both Larimer County(where it is known as Larimer County Road 18) on the west side of WCR ],3 and Weld County on the east side of WCR 13. The speed limit on WCR 54 in the vicinity of'the site is 55 mph. WCR 13 is an unpaved north/south county road between WCR 54 and WCR 52 in the vicinity of the site as well as on the north leg of its intersection with WCR 54. In the vicinity of the site, it forms the border between Weld and Larimer Counties. At its intersection with WCR 54, the north and south legs are stop controlled. Mr.Tug Martin Page 2 September 28,2000 WCR 17 is a paved,two-lane,north/south county road. Its intersection with WCR 54 is Stop controlled on all approaches. Existing and Future Background Traffic Figure 3 illustrates existing peak hour intersection turning movement traffic volumes in the vicinity of the proposed Green Property Gravel Pit at the intersections of WCR 54 with WCR 13 and WCR 17. Truck percentages on WCR 54 and 17 are estimated to be about 12 percent This figure was obtained from the 1996 CDOT Truffle Data for nearby State Highway 257 and assumed to be the same for WCR 54 and 17. Thick percentages on WCR 13 are estimated to be about two percent because it is a gravel road on which truck traffic is not common. Figure 2 also shows the results of a 24-hour road tube traffic count on WCR 13 in the vicinity of the site indicating that the ADT is about 170 vehicles per day(vpd). The traffic counts were conducted in July 2000 by Counter Measures,Inc. Printouts of all count data are contained in Appendix A. According to Larimer County Traffic Engineering,the annual growth rate for Lorimer County Road 18 (which is WCR 54 in Weld County) is about 7.8 percent This corresponds to a 15- year growth factor of 3.09 and was assumed to be the same for nearby roads in Weld County. Year 2005 background traffic volumes were also determined because this is the year in which the Green Property Gravel Pit is expected to be at full operation. The annual growth percentage of 7.8 percent corresponds to a five-year growth factor of 1.46. These growth factors were applied to the existing turning movement volumes to calculate Year 2005 and Year 2015 background volumes as illustrated on Figures 4 and 5, respectively. The back- ground traffic volumes are the future traffic volumes on the area roadways without the expected traffic generated by the site and form the basis for evaluating the impacts that traffic generated by the proposed Green Property Gravel Pit will have on the surrounding roadway system. The background passenger car equivalents (PCE's) are also shown on Figures 4 and 5. According to Section 2.3-4e of the Colorado State Highway Accns Code,"all criteria in the code are based on.automobile operations and performance." Therefore, "To allow for the impact of larger trucks, buses and recreational vehicles, `passenger au equivalents"shall be determined." The Code indicates that for each bus or truck combination 40 feet in length or longer, a passenger car equivalent(PCE)of three is applied while a PCE of two is applied for each vehicle combination between 20 and 40 feet in length. Half of the truck percentage was assumed to have the effect of two passenger cars per truck and the other half was assumed to have the effect of three passenger cars per truck. In a study with a large number of trucks,calculating PCE's is important because, when added to the project-generated PCEs, the need for acceleration and deceleration lanes can be appropriately determined. Estimated Traffic Generation Based on information supplied by the applicant, the following peak daily traffic generation activities are projected: • Cement and Fly Ash Trucks: 6 one-way trips; Mr.Tug Martin Page 3 September 28, 2000 • Concrete Trucks: 120 one-way trips; • Aggregate Trucks: 20 one-way trips; • Light Vehicles: 44 one-way trips. Further breakdown of morning and evening peak-hour trip activity was supplied by the applicant and is shown in Table 1. The breakdown of individual trips by type was estimated based on the total number of expected morning and evening peak hour trips which was supplied by the applicant. As indicated in Table 1, Green Property Gravel Pit is projected to generate a total of 190 vehicle-trips, or 95 vehicles entering and 95 vehicles exiting the site during a work day. Of these, 19 would enter and 14 would exit in the morning peak, while 13 would enter and 19 would exit in the evening peak. Of the morning entering and evening exiting vehicles,about ten are projected to be heavy vehicles while all of the morning exiting and evening entering vehicles are projected to be heavy vehicles.

About 34 percent would be oriented to and from the east on WCR 54 to the east of WCR 13. As the traffic travels east on WCR 54,it is expected to branch off and use some of the north/south roads to travel to various destinations. Further break- down of the traffic distribution to the east of WCR 13 is illustrated on Figure 6. Application Mr.Tug Martin Page 4 September 28, 2000 of t iese percentages to the peak-hour generation estimates of Table 1 yields the intersection traffic assignments shown on Figure 7. Figure 7 also shows the total number of PCE's for the movements affected by the trip distribution and assignment, As with the background traffic, half of the project-generated heavy vehicle percentage was assumed to have the effect of two passenger cars per truck and the other half was assumed to have the effect of three passenger cars per truck. Note that project-generated turning movement volumes are also shown for the intersection of WCR 54 with State Highway 257. 'This was done in order to Illustrate that the project-generated traffic volume added to this intersection is very small and so no capacity analysis was performed for this location. Finally, Figures 8 and 9 illustrate 2005 and 2015 total traffic volumes which are the combination of background(Figures 4 and 5) and project-generated(Figure 7) traffic. Again, PCE's are indicated for affected movements. Capacity Analyses In order to assess the impacts of the proposed Green Property Gravel Pit, related capacity analyses have been performed which compare existing and future background traffic operating conditions (Figures 3, 4, and 5)with those reflecting the addition of project-generated traffic (Figures 9 and 10). The methodology used is that presented in the current edition of the nationally accepted Highwau Capacity Manual published by the Transportation Research Board of the National Academy of Sciences. The concept of Level of Service (LOS) is used as a basis for computing combinations of roadway operating conditions. By definition,six different Levels of Service are used(A,B, C,D,E,and F)with"A"being a relatively free-flow condition and"E" representing the "capacity" of a given intersection or traffic.movement. At the intersection of WCR 54 with WCR 13, under the requirements of the Colorado State Highwau Amass Code, the addition of 2005 project-generated traffic to the 2005 background traffic will require eastbound and westbound right- and left-turn deceleration lanes, respectively. Due to these projections,it is assumed that these lanes will be constructed just before the start of operations for the Green Property Gravel Pit. Therefore, both 2005 back- ground and total traffic have been analyzed with this lane geometry (as well as for the 2015 scenarios). Initial analysis of the WCR 54/WCR 17 intersection under Year 2015 background volumes indicated that some of the approaches would have poor Levels of Service with a four-way Stop. A second analysis was performed using a four-way Stop with a lane configuration in which all approaches would have two through lanes. The results yielded acceptable Levels of Service for all the lanes. However, such a lane configuration (two through lanes on all approaches) used with a four-way Stop is not desirable, therefore, the possibility of using a signal was analyzed: The projected 2015 background traffic volumes at the intersection of WCR 54 with WCR 17 warrant a signal according to the 1988 edition of the Manual on Uniform Traffic Control Devices (MUTCD) and require auxiliary lanes on some of the movements according to the Colorado State Highway Access Code. As volumes increase at this intersection, traffic signal Mr.Tug Martin Page 5 September 28, 2000 wariant analyses should be performed in order to determine the proper time to construct a signal. The background traffic capacity analyses for Year 2015 assume that at the intersection of WCR 54/WCR 17,a signal will be in operation and that auxiliary lanes have been constructed because of the volume requirements in the Colonulo .State Highway Maass Code. The Year 2015 total traffic capacity analysis also uses these same assumptions. - Table 2 summarizes the results of our Level of Service (LOS) analyses. Note also in Table 2 that the various traffic control and lane configuration changes from scenario to scenario are also indicated. Computer printouts containing output from the HCS 3.2 and Synchro 4.0 soft- ware are enclosed. Existing Traffic Levels of Service During the morning and evening peak periods, the four-way Stop controlled intersection of WCR 54 with WCR 17 will operate at LOS"A"and'B",respectively. All approaches operate at LOS"B" or better during both the morning and evening peak periods. At the unsignalized intersection of WCR 54 with WCR 13, all movements operate at LOS`B" or better during both morning and evening peak periods. 2005 Traffic Impacts Year 2005 is when the Green Property Gravel Pit is expected to be at full operation. Under the 2005 background traffic scenario, the four-way Stop controlled intersection of WCR 54 with WCR 17 is expected to operate at LOS "A" and "B" during the morning and evening peak periods, respectively. With the addition of project-generated traffic, the overall intersection LOS is expected to continue to operate at LOS "A" and"B" during the morning and evening peak periods,respectively. All approaches are expected to operate at LOS"B"or better during both the morning and evening peak periods with or without the addition of project-generated traffic. At the unsignalized intersection of WCR 54 with WCR 13, all movements are expected to operate at LOS "B" or better with or without the addition of project-generated during both morning and evening peak periods through Year 2005. 2015 Traffic Impacts As stated previously, initial analysis of the WCR 54/WCR 17 intersection under Year 2015 background volumes indicated that some of the approaches would have poor Levels of Service with a four-way Stop. A second analysis was performed using a four-way Stop with a lane ^ configuration in which all approaches would have two through lanes. The results yielded acceptable Levels of Service for all the lanes. However,such a lane configuration(two through lanes on all approaches) used with a four-way Stop is not desirable. Therefore, the WCR 54/ WCR 17 intersection was analyzed using a traffic signal. r Mr.Tug Martin Page 6 September 28, 2000 Udller the 2015 background traffic scenario, the assumed signalized intersection of WCR 54 with WCR 17 is expected to operate at LOS "B" during both the morning and evening peak periods. With the addition of project-generated traffic,the overall intersection LOS is expected to continue to operate at LOS `B' during the morning and evening peak periods. All move- ments at this intersection are expected to operate at LOS`C'or better during both the morning and evening peak periods with or without the addition of project-generated traffic. At the unsignali..ed intersection of WCR 54 with WCR 13, all movements are expected to operate at LOS `C" or better with or without the addition of project-generated during both morning and evening peak periods through Year 2015. Average Daily Traffic Impacts Figure 10 shows the average daily impacts due to the project-generated traffic including the daily number of heavy vehicles generated by the proposed Green Property Gravel Pit. The average daily impacts are minimal, indicating that by Year 2015, it is estimated that the project-generated traffic will be accountable for less than two percent of the daily traffic on Larimer County Road 18 west of WCR 13 and less than one percent of the daily traffic on WCR 54 east of WCR 13. The project-generated traffic will account for about 26 percent of the traffic on WCR 13. Gravel roads with average daily traffic volumes exceeding 400 vehicles per day are generally considered good candidates for paving. WCR 13, in the vicinity of the site will exceed this threshold. Truck Impacts on Pavement Condition The destructive effect of repeated wheel loads is the major factor which contributes to the deterioration of roadway pavements. Since both the magnitude of the load and the number of repetitions are important,provision is made in pavement design procedures to allow for the effects of the number and weight of all axle loads expected during the design period. CDOT uses pavement design procedures which convert traffic data to 18 Kip equivalent single-axle load applications (18K ESAL). Eighteen Kip or 18,000 lbs is the maximum legal load allowed on a single axle.CDOT uses the following load equivalency factors for flexible pavement design: - passenger vehicle: 0.003 - single-unit trucks: 0.249 - combination trucks: 1.087 The latter category includes most of the concrete trucks, dump trucks, and tractor trailer combinations that would be hauling materials to and from the Green Property Gravel Pit. Eighteen Kip ESAL's have been calculated for the Green Property Gravel Pit on WCR 13, Larimer County Road 18, and WCR 54 using the CDOT load equivalency factors and assumptions regarding the breakdown of traffic into the various vehicle classifications. Based on these assumptions,the Green Property Gravel Pit will generate about 195,800 ESALs over the life of the project. On Larimer County Road 18 immediately west of WCR 13, the total number of ESALS will be about 128,800 while the total number of ESALs on WCR 54 immediately east of WCR 13 will be about 67,000. Over the life of the project, the traffic Mr.Tug Martin Page 7 September 28, 2000 generated by the Green Property Gravel Pit will account for approximately 96 percent of the total number of ESALs on WCR 13 from its intersection with WCR 54 to the entrance to the Green Property Gravel Pit. Additionally the traffic generated by the Green property Gravel Pit will account for approximately five percent of the total number of ESALs on Larimer County Road 18 immediately west of WCR 13 and about ten percent of the total number of ESALs on WCR 54 immediately east of WCR 13. The results of the ESAL analyses are contained in Tables 3, 4, and 5. Recommendations At the intersection of WCR 54 (also Larimer County Road 18) it is recommended that east- bound right-turn and westbound left-turn deceleration lanes be constructed just before the start of operations at the Green Property Gravel Pit. The Colorado State Hwhwau Access Code sets forth the deceleration and taper lengths based on the speed and classification of the high- way while the storage length is based on the number of vehicles using the deceleration lane. Based on these requirements, the following recommendations are made regarding the inter- section of WCR 54 with WCR 13: 1. Based on the 2015 total traffic volumes that will use the eastbound right-and west- bound left-turn deceleration lanes,the lengths required by the Colorado State High- way Access Code standards are calculated to be as follows: Eastbound right-turn taper length- 225 feet; Eastbound right-turn deceleration length- 380 feet; Westbound left-turn taper length- 225 feet; Westbound left-turn deceleration and storage length - 405 feet. 2. WCR 13 should be paved from its intersection with WCR 54 on the north to the site access on the south according to Weld and Larimer County specifications. Conclusions Based upon the foregoing analyses, the following conclusions can be made concerning the traffic impacts of the proposed Green Property Gravel Pit 1. The Green Property Gravel Pit is expected to generate a total of 146 heavy vehicle- trips and 44 passenger vehicle/pickup trips on an average work day. During the morning peak-hour, about 19 entering and 14 exiting vehicles (10 entering and 14 exiting heavy vehicles) will be generated while during the evening peak-hour, 13 entering and 19 exiting vehicles (13 entering and 10 exiting heavy vehicles) will be generated. 2. About 66 percent of the traffic generated by the Green Property Gravel Pit would be onented to and from the west on Larimer County Road 18 to the west of WCR 13. About 34 percent would be oriented to and from the east on WCR 54 to the east of WCR 13. Mr.Tug Martin Page 8 September 28, 2000 *"3. Under the existing and assumed future lane configurations and intersection traffic controls, all movements at the intersections of WCR 54 with WCR 13 and WCR 17 are expected to operate at LOS`C" or better with or without the addition of project- generated traffic during the morning and evening peak periods through Year 2015. 4. Over the life of the project,the traffic generated by the Green Property Gravel Pit will account for approximately 96 percent of the total number of ESALs on WCR 13 from its intersection with WCR 54 to the entrance to the Green Property Gravel Pit. 5. The intersection of WCR 54 and the site access should be improved to include east- bound right-turn and westbound left-turn deceleration lanes. Based on the 2015 total traffic volumes that will use the eastbound right- and westbound left-turn deceleration lanes,the lengths required by the Colorado Sto e Highway Anrwss Code standards are calculated to be as follows: Eastbound right-turn taper length- 225 feet; Eastbound right-turn deceleration length - 380 feet; Westbound left-turn taper length - 225 feet; Westbound left-turn deceleration and storage length - 405 feet. r 6. WCR 13 should be paved from its intersection with WCR 54 on the north to the site 'access on the south according to Weld and Larimer County specifications. 7. The traffic impacts of the Green Property Gravel Pit can be accommodated by the existing roadway system with the improvements recommended herein.
