The subject property is approximately 301 acres located in the West '/2 and W '/2 of the NE IA of Section 21, as well as the East 1/2 of the Southeast IA of Section 20, Township 3 North, Range 67 West of the 6th P.M., in Weld County, Colorado. (See the Vicinity Map in Section 44.2.1.) The property is approximately halfway between County Road 17 and County Road 19. State Highway 66 marks the southern border of the property. Existing zoning and use of the subject property and surrounding properties is agricultural. The intent is to mine the property to recover a substantial sand and gravel reserve that is of significant commercial quality and quantity. The project will last approximately 20 years, and this time frame is highly dependent upon market conditions. The Applicant also requests that on-site asphalt and concrete batch plants utilize some of the aggregate produced. The end use of the property after reclamation will primarily be for wildlife and some potential residential development. Reclamation will be sequential and run concurrently with mining operations. The Town of Firestone property will be used for truck and equipment access during mining, and included with the reclamation plans thereafter. A temporary bike path system on Kurtz Ranch property will divert public pedestrian traffic out of the zone of mining operations and provide connections to open space trails to the north and south. The remainder of this application package discusses the proposal in detail and addresses all of the requirements of the Zoning Ordinance. 98023..WW D Kurtz Ranch Sand and Gravel Mine WC USR 1 802 1 Aggregate Industries West Central Region April Banks and Gesso, LLC SPECIFIC WELD COUNTY REQUIREMENTS 1 - Requirement 44.1 - Application Form (see following pages) Kurtz Ranch Sand and Gravel Mine WC USR 2 98023.WD Aggregate Industries West Central Region April 2001 Banks and Gesso, LLC 3 — Requirement 44.3 — Supporting Documents 44.3.1 - Colorado Mined Land Reclamation Board Submittal This separate document is enclosed at the end of this application package. 44.3.2 - Plans for Obtaining Water Supplies There is no evidence that obtaining additional water supplies will be required for this project. 44.3.3 — Cross Sections of Drainage Structures There are no drainage structures required by this project. 44.3.4 — Profile and Typical Cross Section of Haul Roads Internal haul roads will be utilized in the early phases of the mining process and will have access through the Town of Firestone property.

Tractor trailers at approximately 85,000 pounds or tandems at approximately 55,000 pounds will be used to haul aggregates and hot-mix asphalt from the site. Ready-mixed concrete trucks (with rotating drums), would haul ready-mixed concrete from the project site. Based upon the use of these trucks, importing some materials, and using a 300-day per year working schedule gives an average of 180 truck round trips - 160 trips per day for haul trucks. Additional traffic will be generated by employees, sales people, and visitors to the site. As an estimate, these trips will account for approximately 56 additional trips per day, which includes automobiles and light trucks (pickup trucks). Aggregate Industries, Inc. proposes to pave the entrance from Colorado State Highway 66 to current CDOT standards, as required by their access permit. The Applicant will utilize chemical dust suppressants and water trucks to control dust on on-site roads. Please see Traffic Impact Study under Attachment 'H'.

INTRODUCTION Project Overview This traffic impact study addresses the capacity, geometric, and control . requirements associated with the proposed operation of the Kurtz Ranch Sand and Gravel Mine located in Weld County, Colorado. Site Location and Study Area Boundaries The site is north of State Highway 66 between Weld County Road 17 and Weld County Road 19. The study area to be examined in this traffic impact analysis encompasses the site access drive to State Highway 66. The site location is shown on Figure 1. Description of Site The land for this development is currently vacant. The proposed project includes a commercial land and gravel mining facility. Access to the site is proposed via one full-movement access drive to State Highway 66. This access is proposed to align with a proposed access to the Varra Property (Sand Land) on the south side of State Highway 66. a I I I I I I 2 I J N Ill Not to Scale ■ I I I L County Road 14 V \ _- . - ,- County Road 1212 N Jl \ - County Road 32 U *SITE* • lillr--- -----------" oo County Road ld IICounty Road[E 0 X X II Figure 1 al SITE LOCATION U I I II. PROPOSED PROJECT TRAFFIC Trip Generation Since standard traffic generation characteristics are not available for this type of facility, the mining operators have prepared an estimate of daily and hourly trips based on projected employment and truck trips. This information is presented in Table 1. I Adjustments to Trip Generation Rates No trip reductions were taken in the traffic study in an effort to provide a conser- vative analysis. I Trip Distribution The overall directional distribution of the site-generated traffic was determined based on the location of the site within Weld County, and the surrounding street system. The overall trip distribution used in the analysis assumes 90 percent of the site-generated trips will be to and from the east (I-25 corridor). Project Trip Assignment Traffic assignment is how the generated and distributed trips are expected to be loaded on the roadway network. The site-generated trip assignments are shown on Figure 2.

PROJECT IMPACTS Peak Hour Intersection Level of Service The Unsignalized Intersection Analysis technique, as published in the Highway Capacity Manual by the Transportation Research Board in 1994, was used to analyze the site access. This technique allows for the determination of the intersection level of service based on congestion and delay of each traffic movement. Traffic analyses were completed for total traffic (with project). The results of these analyses are provided in Table 2. Definitions of level of service are given in Appendix B. The capacity worksheets are provided in Appendix C. The full-movement access point to State Highway 66 is projected to operate acceptably.

At the site location, State Highway 66 is a RA Category Highway with a posted speed of 65 mph. According to Tables 4-5 and 4-6 of the 1998 State Highway Access Code, the site access drive will require construction of a left turn deceleration lane (800 feet in length, including a 25:1 taper). Although the right turns do not warrant a deceleration or acceleration lane, both lanes are recommended due to the heavy truck volume. The right turn deceleration lane should be 800 feet and the acceleration lane should be 1,380 feet. Both lane lengths include a 25:1 taper. I I I 1 I c 1 12 I VI. CONCLUSION This study assessed the traffic impacts of the proposed Kurtz Ranch Sand and Gravel Mine located in Weld County, Colorado. Traffic operations at the site access drive and State Highway 66 will function well as an unsignalized intersection. Auxiliary lanes will need to be constructed with development of this site. Although the right turn ND lanes are not required according to projected traffic volumes they are being recommended due to the high proportion of large trucks using the access.

Washington, D.C., 1985. ihl N LEVEL OF SERVICE CRITERIA FOR SIGNALIZED INTERSECTIONS Level-of-service for signalized intersections is defined in terms of delay. Delay is a measure of driver discomfort, frustration, fuel consumption, and lost travel time. Delay is a complex measure, and is dependent on a number of variables, including the quality of [the signal] progression, the cycle length, the green time ratio, and the v/c ratio for the lane group or approach in question. Level-of-service A describes operations with very low delay, i.e., less than 5.0 seconds per vehicle. This occurs when progression is extremely favorable, and most vehicles arrive during the green phase. Most vehicles do not stop at all. Short cycle lengths may also contribute to low delay. Level-of-service B describes operations with delay in the range of 5.1 to 15.0 seconds per vehicle. This generally occurs with good progression and/or short cycle lengths. More vehicles stop than for LOS A, causing higher levels of average delay. Level-of-service C describes operations with delay in the range of 15.1 to 25 seconds per vehicle. These higher delays may result from fair progression and/or longer cycle lengths. Individual cycle failures may begin to appear at this level. The number of vehicles stopping is significant at this level, although many still pass through the intersection without stopping. Level-of-service D describes operations with delay in the range of 25.1 to 40.0 seconds per vehicle. At level D, the influence of congestion becomes more noticeable. Longer delays may result from some combination of unfavorable progression, long cycle lengths, or high v/c ratios. Many vehicles stop, and the proportion of vehicles not stopping declines. Individual cycle failures are noticeable. Level-of-service E describes operations with delay in the range of 40.1 to 60.0 seconds per vehicle. This is considered to be the limit of acceptable delay. These high delay values generally indicate poor progression, long cycle lengths, and high v/c ratios. Individual cycle failures are frequent occurances. Level-of-service F describes operations with delay in excess of 60.0 seconds per vehicle. This is considered to be unacceptable to most drivers. This condition often occurs with N oversaturation, i.e., when arrival flow rates exceed the capacity of the intersection. It may also occur at high v/c ratios below 1.00 with many individual cycle failures. Poor progression and long cycle lengths may also be major contributing causes to such delay levels. ®1 I t txcerptea trom Hlgnw-y capacity Manual, Special Keport 209, I ransportation Kesearcn soara, national Research Council, Washington D.C., 1985.

The proposed post-mining land uses are compatible with the agricultural uses in the surrounding area. In addition, the post-mining uses are consistent with allowed uses permitted in the Weld County Zoning Ordinance. The property will also provide an interim bike path during the operation of the mining facility. The interim bike path will connect to the existing path located at the south property line, continue along the east property line and reconnect to the Town of Firestone easement at the midpoint of the east property line. The reclamation plan is presented as follows. Reclamation Process Reclamation will take place concurrently with mining with no more than 70 acres being disturbed at any one time before reclamation commences. Since there is effectively no reclamation of the pond bottom, the 70 acres corresponds to the plant site, settling ponds and perimeter slope/pond backfill. Vegetation will be removed, and then available topsoil will be stripped and stockpiled for later use in revegetation. Any surplus topsoil materials, corresponding to the acreage proposed to be inundated, will be designated for upper zones of ponds backfilled to re-create wetlands. Areas that will be inundated with water will not be replanted. Slopes and upland areas will be topsoiled and revegetated. Kurtz Ranch Sand and Gravel Mine OMG 112 Permit 15 98023.WD Aggregate Industries West Central Region April 2001 Banks and Gesso, LLC Topsoil Preservation Soils on the site vary from sandy loam, loam, and aquolls and aquepts, with surface layers varying from 1 to 13 feet thick. The location of the topsoil stockpiles will be within the permit area and in areas close to final placement. As filled areas in ponds and around the perimeter of the proposed mine pit limits are completed, topsoil will immediately be respread in preparation for revegetation. Soil material that is stockpiled for later use in revegetation will be placed on a stable surface within the permit area and will be clearly marked. These topsoil stockpiles will be protected from disturbances associated with the mining operation and from wind and water erosion, compaction, and other disturbances that would reduce its capability to support vegetation. The stockpiles will be seeded with a temporary cover when stockpiles will remain in place for more than one growing season. Soil materials will be subjected to physical and chemical soil analysis to determine possible means of enhancing plant growth. Soil analysis may include pH, texture, specific conductance, sodium absorption ratio, nitrate nitrogen, plant available phosphorous and potassium. It is expected that these soil test results will indicate little enhancement is necessary for successful revegetation. Kurtz Ranch Sand and Gravel Mine DMG 112 Permit 16 98023.WD Aggregate Industries West Central Region April 2001 Banks and Gesso, LLC Regrading and Shaping Backfill on ponds will occur with adequate compaction to ensure slope stability. All pond slopes will be backfilled at a 3:1 slope, except where shallower slopes are used for wetland shorelines at the anticipated final water elevation in each pond. This will create areas of shallow waters favored by fish and waterfowl, adjacent to re-created emergent wetland areas. Topsoil will be placed and seeded from this elevation up the slope to the property line. Excess overburden will be placed over the 3:1 slopes, as indicated on Exhibit F, to create an undulating shore line, with rounded corners, prior to topsoil placement. Approximately 6 to12 inches of topsoil will be placed on all 3:1 slopes, both above and below the expected water line. Contour furrows will be established on the shoreline slopes to reduce erosion and encourage stable plant growth. Topsoil Replacement Topsoil replacement (approximately 6-12 inches) will occur following regrading and scarification of the surface. Placement will primarily occur during late summer and fall. This procedure limits the time that topsoil is exposed prior to revegetation and avoids moving topsoil when it is frozen or too wet. The seeding will typically occur in the fall, to expose the soils to sufficient winter moisture for successful germination in the spring, when the ground is often too wet to seed. Kurtz Ranch Sand and Gravel Mine DMG 112 Permit 17 98023.WD Aggregate Industries West Central Region April 2001 Banks and Gesso, LLC Re-vegetation Re-vegetation of non-wetland areas will utilize predominantly native grasses. The Natural Resources Conservation Service conducted a field visit and range assessment of the site. As indicated in the attached report, the site is classified as a salt meadow, with soil types varying in alkalinity levels. As recommended, the Applicant will obtain topsoil samples in advance of seeding operations and submit the test results to the Conservation Service office for a specific seed mix recommendation. The anticipated grass species are listed in Table E-1, without specific rates. The seed mix for temporary covering of berms and topsoil piles is provided in Table E-2. Re-vegetation of wetland areas will utilize the plant types listed in Table E-3. Prior to mining, shallow groundwater monitoring wells will be installed at various interior locations. These wells will be monitored to determine seasonal groundwater fluctuations of wetland and non-wetland areas prior to disturbance. This data will be utilized in determining finished grade of re-created wetlands, as well as to predict the normal water elevation in ponds. Seeding Method Seeding will be accomplished using either a seed drill properly equipped to meter the native grasses of the mix, or using broadcast followed by harrowing or raking. Seeding will be done in the fall after October 1st to facilitate successful Kurtz Ranch Sand and Gravel Mine DING 112 Permit 18 98023.WD Aggregate Industries West Central Region April 2001 Banks and Gesso, LLC germination. Following seeding, the area will be covered and crimped with certified clean straw at a rate of approximately two tons per acre. Weed Management The development of weeds will be closely monitored to ascertain the need for control. Of greatest concern will be the development of Canada Thistle, Russian Thistle, Mustard, Kosha, Field Bindweed, and possibly Rye. If any of these appear during the first year after seeding, they will be controlled with several mowing operations, at specific times. The presence of annual and biennial weeds during the first few years after seeding is normal and can be expected to diminish thereafter. The use of herbicides for weed control should wait at least one year after seeding, to allow the native grasses to gain stamina. The Applicant assumes responsibility for weed control on all areas of the site affected by mining operations. The Applicant's weed control program will also supplement the owner/lessor's weed control program on undisturbed areas of the site where requested or deemed necessary.

Overall condition of this site varies from Fair to Good. Please refer to the enclosed copy of the Range Site description for more forage details . Dominant vegetative cover includes saltgrass on the majority of open areas, Alkali bluegrass under the cover of the trees, and where the water table is high, the sedges, rushes and cattails are dominant . SEED MIX RECOMMENDATIONS AA AA.......A AAA A AA A A A A A A There is a variety of soil present at this site. Listed in descending order, Soil #3, Aquolls and Aquents with a gravelly substratum, Soil #10, an Altvan Loam, and Soil #1 a Bankard Sandy Loam. Judging on the species present at this site, there are portions that could be very alkaline and/or saline. The extent of the alkali/saline problem will determine which grass species will or will not work at this site. I recommend that a soils test be completed after reclamation and prior to revegetation. I can then make a complete recommendation based on that soils test. To give you an example of a few of the species that could work at this site, Inland saltgrass, Alkali sacaton, NEWHY wheatgrass, Intermediate/Pubescent wheatgrass, Alkali bluegrass are all potential species . Knowing the exact future intended use will also be helpful, as there are species that are more palatable to cattle than others, while some create better wildlife habitat. Stan, please call me if you have any questions or if I have left out any information that you needed. Sincerely, Donna Sue Turbett �" Rangeland Management Specialist Hello
