The proposed subdivision is located to the south of the West Rifle I-70 interchange, in sections 13, 14 and 24, Township 6 South, Range 94 West, of the Sixth Principal Meridian. The existing zoning of the parcel is Resource Lands. We are proposing changing the zoning to Commercial General. The parcel is 21.777 acres, more or less, being subdivided into five commercial lots. Lot 2 contains the existing building, well and septic field for Johnson Construction. No residential dwelling units are being proposed for this subdivision. The proposed total non-residential floor space is 474,303 square feet, which is a floor area ratio of 0.5/1.0. The off-street parking spaces are not being proposed with this submittal. It is anticipated that off-street parking spaces will be provided at the time of the building permit review for the individual lots. WATER SUPPLY The source of the water supply will be a well located on Lot 2. According to the 4 hour well test performed by Samuelson Pump Co, Inc., the production of the well is 15 gallons per minute. The • test results are included with this submittal. A pressurized distribution system is proposed to supply water to the lots. A reverse osmosis water treatment system will be installed to treat the water (due to the future potential of radioactive particle contamination). The water quality test results are also included in this submittal. • • SEWAGE DISPOSAL All of the lots will be on individual sewage disposal systems (ISDS). Lot 2 has a county approved ISDS. The percolation test results for Lot 2 was 22 minutes per inch. The Department of Health will require a site application only if the sewage flow is 2,000 gallons per day average or 3,000 gallons per day peak flow or greater. SOIL TYPES According to the Soil Conservation Services Soils Map, the predominant soils type is Arvada loam. The applicable portion of the SCS map and tables are included in this submittal. • IMPACTS OF THE SUBDIVISION There are no lakes or streams present within this development. This parcel is separated from the Colorado River by the Union Pacific Railroad right of way. Thus, impacts to major watercourses should by negligible. A minor drainage way is present between Lots 3 & 4. Drainage best management practices should be used to mitigate potential impacts. Due to the gentle to moderate slopes present on the site, the impacts to the existing topography should be reasonable. • • 923 Cooper Avenue • Glenwood Springs, CO 81601 Telephone: (970) 945-8676 • FAX: (970) 945-2555 • • • • • • • • • • • RADIATION HAZARDS According to the "Private Well / Spring Paper, Rifle, Colorado, Sites", prepared by the Department of Energy (DOE) dated May 1995, the contamination flume from the New Rifle Tailings Site does not reach the existing well located on this parcel. However, according to this report, there are high levels of sulfates naturally occurring in this aquifer. DOE claims these high concentrations of minerals are not due to contamination from their site. However, the water quality results from Grand Junction Laboratories indicates gross alpha particles are present above the Colorado Department of Health standards. We are recommending reverse osmosis on the drinking water for all of the proposed lots. The water quality results are included in this submittal. ACCESS TO LOTS The access to the lots will be off of the I-70 frontage road. The lots will have to obtain a CDOT access permit to construct the driveways to the lots. SHALLOW UTILITIES Electricity and natural gas is provided by Public Service, and is present along the northern boundary of the subdivision. Telephone will be provided by US West. It is present approximately one mile from the site. It is in the process of being extended for Johnson Construction. Cable television is not m the vicinity. • Jan. 29 '98 9:55 SANYU • • FAX +303-625-2888 P. 5 SAMUELSON PUMP CO. INC. P.O.

Surface runoff is medium, and the erosion hazard is moderate. • This soil is used mainly for wildlife habitat and limited grazing. The native vegetation on this soil is mainly Gambel oak, serviceberry, elk sedge, and bromes. When range condition deteriorates, forbs and woody shrubs increase. When the range is in poor condition, Kentucky bluegrass, undesirable weeds, and annual plants are abundant. Properly managing grazing main- tains and improves range condition. Mule deer, elk, cottontail rabbit, wild turkey, and blue grouse find habitat on this soil. Community development and sanitary facilities are lim- ited by steep slopes and low strength. • This soil is in capability subclass Vile, nonirrigated. 2—Arle-Ansari-Rock outcrop complex, 12 to 65 percent slopes. This complex consists of strongly slop- ing to steep soils and Rock outcrop on mountainsides and sloping alluvial fans. Elevation ranges from 5,500 to 7,500 feet. The soils formed in alluvium derived from red -bed shale and sandstone. The average annual pre- cipitation is about 16 inches, the average annual air temperature is about 42 degrees F, and the average frost -free period is about 100 days. The Arle soil makes up about 45 percent of the com- plex, the Ansari soil makes up about 35 percent, and • Rock outcrop makes up about 20 percent. The Arle soil is moderately deep and well drained. Typically, the surface layer is reddish brown very stony loam about 10 inches thick. The subsoil and substratum are reddish brown very stony loam about 22 inches thick. Soft reddish brown sandstone and shale are at a depth • of 32 inches. Permeability of the Arle soil is moderate, and available water capacity is low. Effective rooting depth is about 20 to 40 inches. Surface runoff is medium, and the erosion hazard is severe. The Ansari soil is shallow and well drained. Typically, the surface layer is reddish brown loam about 10 inches • thick. The substratum is reddish brown stony loam. Bed- rock is hard, reddish brown sandstone. Permeability of the Ansari soil is moderate, and availa- ble water capacity is low. Effective rooting depth is about 10 to 20 inches. Surface runoff is rapid, and the erosion hazard is severe. • Rock outcrop is mainly red sandstone.

The native vegetation on the Ansari soil is mainly Indian ricegrass, wheatgrass, and sagebrush. When range condition deteriorates, forbs and shrubs increase. When the range is in poor condition, undesira- ble weeds and annual plants are numerous. Properly managing grazing maintains and improves range condi- tion. Mule deer, rabbit, and grouse find habitat on these soils. Use of this complex for community development or as a source of construction material is limited mainly by depth to rock, steep slopes, thin layers of borrow materi- al, and large stones. Special design can overcome these limitations. Drainage and structures to control runoff from snowmelt reduce erosion around construction sites and roads. This complex is in capability subclass Vile, nonirrigat- ed. 3—Arvada loam, 1 to 6 percent slopes. This deep, well drained, sloping soil is on fans and high terraces (fig. 4). Elevation ranges from 5,100 to 6,200 feet. This soil formed in highly saline alluvium derived from sand- stone and shale. The average annual precipitation is about 12 inches, the average annual air temperature is about 48 degrees F, and the average frost -free period is about 120 days. Typically, the surface layer is strongly alkaline or very strongly alkaline, pale brown loam about 3 inches thick. The subsoil is brown silty clay loam about 14 inches thick. The substratum is light brown or brown silty clay loam to a depth of 60 inches. Included with this soil in mapping are small areas of Limon, Kim, Heldt, and Wann soils. Also included are some soils that are high in silt. Permeability is very slow, and available water capacity is moderate. Effective rooting depth is 60 inches or more. Organic matter content of the surface layer is low. Surface runoff is medium, and the erosion hazard is moderate. This soil is used mainly for wildlife habitat, limited grazing, and some irrigated farming. Irrigated crops produce very poorly because the soil takes water in very slowly and is droughty. Leaching is needed to remove excess salts if this soil is to be irrigat- ed. Soil amendments containing sulphur are helpful in leaching the salt. The native vegetation on this soil is mainly saltgrass, alkali sacaton, and greasewood. When range condition deteriorates, forbs and shrubs increase. Properly managing grazing maintains and im- proves range condition. Seeding improves range in poor condition. Western wheatgrass, alkali sacaton, and tall: wheatgrass are suitable for seeding. Preparing seedbed and drilling the seed are good practices. Irrigat- ing new seedings is necessary for successful establish- A • RIFLE AREA, COLORADO 11 • ment. Reducing brush improves the range if the grass understory is adequate. Cottontail rabbit and pheasant find shelter on this soil if they can obtain food in surrounding areas. Use of this soil for sanitary facilities, for community development, and as a source of construction material is limited by the high shrink -swell potential, slow permeabil- ity, clayey textures, and salinity. This soil is in capability subclass Vlls, irrigated and nonirrigated. 4—Arvada loam, 6 to 20 percent slopes. This deep, Dwell drained, sloping soil is on fans and high terraces. Elevation ranges from 5,100 to 6,200 feet. This soil formed in highly saline alluvium derived from sandstone and shale. The average annual precipitation is about 12 inches, average annual air temperature is about 48 de- grees F, and the average frost -free period is about 120 . days. Typically, the surface layer is moderately alkaline, pale brown loam about 3 inches thick. The subsoil is brown silty clay loam about 14 inches thick. The substratum is light brown or brown silty clay loam to a depth of 60 inches. Included with this soil in mapping are small areas of Limon, Kim, and Heldt soils.

Sur- face runoff is moderately rapid, and the erosion hazard is severe. Ali This soil is used mainly for wildlife habitat and limited IF grazing. The native vegetation on this soil is mainly sagebrush, greasewood, and wheatgrass. When range condition deteriorates, grasses decrease and weedy forbs, cheatgrass, big sagebrush, and greasewood increase. Properly managing grazing main- • tains and improves range condition. Seeding improves range in poor condition. Western wheatgrass and tall wheatgrass are suitable for seeding. Preparing a seedbed and drilling the seed are good practices. Irrigat- ing new seedings is necessary for successful establish- ment. Brush should not be reduced because grass pro- duction is low and some desirable native shrubs could i be destroyed. Cottontail and pheasants find shelter on this soil if they can obtain food in surrounding areas. Use of this soil for sanitary facilities and as a source of construction material is limited by the large amounts of clay and salts. This soil is corrosive to steel and con- e crete. Community development is limited by high shrink - swell potential, salinity, and steep slopes. This soil is in capability subclass VIIs, nonirrigated. 5—Ascalon fine sandy loam, 1 to 6 percent slopes. This deep, well drained, nearly level to gently sloping soil • is on mesas, alluvial fans, and terraces. Elevation ranges from 5,000 to 6,500 feet. The soil formed in alluvium derived from sandstone and shale. The average annual precipitation is about 14 inches, the average annual air temperature is about 48 degrees F, and the average frost -free period is about 120 days. Typically, the surface layer is brown fine sandy loam about 5 inches thick. The subsoil is brown and yellowish brown sandy clay loam about 30 inches thick. The sub- stratum is very pale brown sandy clay loam to a depth of 60 inches. Included with this soil in mapping are small areas of Olney and Potts soils that have slopes of 1 to 6 percent. Permeability is moderate, and available water capacity is moderate. Effective rooting depth is 60 inches. Sur- face runoff is slow, and the erosion hazard is moderate. This soil is used mainly for irrigated crops, hay, and pasture. Some areas are used for grazing and wildlife habitat. This soil is irrigated mainly by corrugations. Sprinklers are also suitable. This soil erodes easily. Such practices as minimum tillage, grassed waterways, and tail water control reduce the danger of excessive erosion. Drop structures in irrigation ditches control water and prevent excessive ditch erosion. The native vegetation on this soil is mainly need- leandthread, wheatgrasses, and sagebrush. When range condition deteriorates, forbs and shrubs increase. When the range is in poor condition, undesira- ble weeds and annual plants are numerous. Properly managing grazing maintains and improves range condi- tion. Reducing brush also improves the range. Seeding improves range in poor condition. Pubescent wheat - grass, western wheatgrass, and big bluegrass are suit- able for seeding. Preparing a seedbed and drilling the seed are good practices. This soil has potential as habitat for pheasant, cotton- tail rabbit, mourning dove, and squirrel. These animals mostly obtain food and shelter in areas of crops and hay. This soil has few limitations for community develop- ment. Low strength and frost action affect structures and roads. Community sewage systems will be needed if the population density increases. This soil is in capability subclasses Ille, irrigated, and IVe, nonirrigated. 6—Ascalon fine sandy loam, 6 to 12 percent slopes. This deep, well drained, moderately sloping to rolling soil is on mesas, terraces, sides of valleys, and alluvial fans. Elevation ranges from 5,000 to 6,500 feet.

Typically, the surface layer is brown fine sandy loam about 5 inches thick. The subsoil is brown and yellowish 36 more. Organic matter content is high. Surface runoff is • slow, and the erosion hazard is slight. This soil is occa- sionally flooded for brief periods between April and Sep- tember. This soil is used mainly for grazing, wildlife habitat, and limited irrigated hay. Good management of water and fertilizer maintains or improves the production of native • hay. The native vegetation on this soil is mainly wildrye, wheatgrass, needlegrass, and small amounts of forbs and shrubs. When range condition deteriorates, dandelion, yarrow, rabbitbrush, big sagebrush, and Kentucky bluegrass in- crease. Properly managing grazing maintains and im- • proves range condition. Basin wildrye, slender wheat - grass, and western wheatgrass are suitable for seeding. Preparing a seedbed and drilling the seed are good practices. Fencing protects this more productive soil. This soil is lower than surrounding soils and usually con- tains the water supply for livestock. Reducing brush im- proves the range. Mule deer, snowshoe hare, elk, coyote, and blue grouse find habitat on this soil. Community development is limited by flooding. This soil is a good source of topsoil. This soil is in capability subclass VIe, nonirrigated. • 64—Tanna silty clay loam, 25 to 45 percent slopes. This moderately deep, well drained soil is on mountain- sides. Elevation ranges from 6,500 to 7,600 feet. This soil formed in material weathered from shale. The aver- age annual precipitation is about 17 inches, the average annual air temperature is about 43 degrees F, and the average frost -free period is about 100 days.

The substratum is light gray channery clay loam about 6 inches thick. Weathered shale is at a depth of 30 inches. Included with this soil in mapping are small areas of • Dollard clay and shale outcrop on steep and very steep mountainsides. These areas make up 10 to 15 percent of the map unit. Permeability is slow, and available water capacity is low. Effective rooting depth is 20 to 40 inches. Surface runoff is rapid, and the erosion hazard is severe. This soil is used mainly for wildlife habitat and limited grazing. The native vegetation on this soil is mainly Gambel oak, serviceberry, snowberry, and elk sedge. When range condition deteriorates, forbs and shrubs increase. When the range is in poor condition, Kentucky bluegrass, weeds, and annual plants are numerous. • Properly managing grazing maintains and improves range condition. Mule deer, wild turkey, and cottontail rabbit find habitat on this soil. w S' • SOIL SURVEY Use of this soil for community development, for sani- tary facilities, and as a source of construction material is limited by steep slopes, high clay content, low strength, depth to bedrock and shrink -swell potential. Road con- struction and building foundations can be designed to reduce the effects of shrinking and swelling. A good drainage system reduces soil slumping. This soil is in capability subclass Vile, nonirrigated. 65—Torrifluvents, nearly level. This broadly defined unit consists of deep, well drained to somewhat poorly drained, nearly level soils on flood plains adjacent to the Colorado and Roaring Fork Rivers and their major tribu- taries. Slope is 0 to 6 percent. The soils formed in alluvium. These soils are stratified and vary widely in texture and depth. The surface layer ranges from loamy sand and fine sandy loam to silty loam and clay loam. The underlying layers are generally sandy loam or loam strati- fied with sand, gravel, and cobbles. In some areas gravel and cobbles are on or near the surface. The water table fluctuates between depths of 2 and 4 feet and in some years is near the surface during spring runoff from snowmelt. These soils are subject to brief, occasional flooding late in spring and early in summer. Included in mapping are small isolated areas of Wann soils that have slopes of 1 to 3 percent. Small areas of soils that are moderately to severely affected by alkali are identified by an alkali spot symbol. Small, isolated areas where water stands at or near the surface all year are identified by wet spot and marsh spot symbols. These areas make up 15 percent of the map unit. These soils are used for wildlife habitat, recreation, and some grazing. The native vegetation is mainly cottonwood, willow, tamarisk and water -tolerant grasses, sedges, and rushes. In many areas these soils are suited to production of Fremont cottonwood. The soils are capable of producing 230 board feet of timber per acre from a fully stocked, even -aged stand of 40 -year-old trees. Where these soils are accessible, they provide shelter and forage for livestock. Mule deer, cottontail rabbit, coyote, bobcat, ducks, geese, and other native birds find food and shelter on these soils. Where feasible, planting food plots, trees and shrubs, and nesting cover enhances the habitat for upland wildlife. Where the water table is high, open water for waterfowl and fish can be developed by blast- ing or by excavating. These soils have potential for recreation. Wildlife is abundant, and the nearby rivers can be used for rafting and canoeing. Community development is very limited by flooding, the seasonal high water table, and variable texture. Onsite investigation is necessary. These soils are in capability subclass Vllw, nonirrigat- ed. • 134 SOIL SURVEY TABLE 13. --ENGINEERING INDEX PROPERTIES •(The symbol < means less than; > means more than.

Bauer Lacy Park Sketch Plan 3/11/98 The subject tract is nearly 21.8 acres in size and located on the southwest side of the west rifle interstate 70 interchange. Slope across the tract is quite gentle and the tract is the site o f lacy park construction. Adjacent land uses include commercial, industrial and agricultural. The subdivision sketch plan proposes a total of 5 lots, ranging in size between 3.3 acres and 6.3 acres. No specific development plan is being proposed at this time; however, the application contemplates a future rezoning of the tract to commercial general. No residential uses are being proposed. The only review agency commenting to date has been the rifle fire protection district who has stated the tract is within its response area and states the uniform fire code for commercial occupancies requires 1500 gpm fire flow, which should be provided. Notes additionally that fire hydrants be located within 500 feet of structures. In terms of zoning, the tract is within the resource lands zone district, and within the gentle slopes and lower valley floor sub -classification. All proposed lots are in excess of the 2 acre minimum requirement. The existing construction business has received a special use permit and any similar land use would also require a similar permit. If the applicant intends to rezone the property at a later time, then I would recommend a rezoning application include the entire property so that the application could be considered in a comprehensive manner. The application proposes setbacks of 50 feet in the front, 10 feet on the sides and 25 feet in the rear, which conflict with the setbacks required by the underlying zoning. These setbacks could be amended by rezoning or through special use permit consideration. The water supply would be derived from an existing well that would be shared among the lots. The well has been pump tested and found to produce 15 gallons per minute in a four hour test. The well permit limits the pumping rate and uses which would require amending to become a centralized supply. Additionally, the water supply is required to be designed by a professional engineer and must meet subdivision requirements. The water quality has been tested and found to exceed state limits for gross alpha particles and other analytes. Reverse osmosis is proposed to be utilized for treatment, which apparently is capable of removing the radiation hazards and would likely remove other minerals and compounds. Individual sewage disposal systems are proposed to treat wastewater. The soil conservation service classified the on-site soil as an Arvada loam. When this soil is utilized for building site development and the placement of ISD systems, it is considered to have moderate to severe constraints. The existing structure is served by a conventional ISD system, however. Site specific percolation tests would be required for preliminary plan submittal. I should also note that ISD systems are only allowed to treat human wastes, they are not permitted to treat industrial -type wastes. Access to the subdivision would be from the interstate 70 frontage road, apparently from individual driveways. It appears that the highway right-of-way is sufficiently wide to accommodate additional
