INTRODUCTION The proposed Hammes Subdivision is located adjacent to the Wooden Deer Subdivision's easterly boundary, approximately three miles northeast of the Town of Carbondale as shown on the Vicinity Map (Exhibit A). More specifically, the 44.5 acre parcel of land is a portion of the South Half of the South Half of Section 24, Township 6 South, Range 93 West, of the Sixth Principal Meridian (complete property description is included in Appendix A). The property will be subdivided into four residential lots ranging in size from approximately 7 acres to 17 acres, as shown on the Sketch Plan Drawing (included as Exhibit B). The property is currently zoned A/R/RD, Agricultural/Residential/Rural Density, and no change in zoning is requested. Other than one single family dwelling, the parcel presently sets on a mild ridge in its natural state of mostly pinion trees and sage brush. The pattern of adjacent property ownership is shown on the portion of the county assessor's map which is included in Appendix C. Impacts from the proposed development will be minimal. There are no lakes or perennial streams within the project which could be affected. Site impacts will be minimal with the addition of three new residential dwellings, upgrade of the existing access road to County standards, and a 500 lineal foot extension of the existing access road to the most westerly lot. Fill slopes and cut slopes will be minimal. All disturbed areas will be revegetated with a native grass seed mixture. LAND USE BREAKDOWN 1. Existing zoning is A/R/RD - no required change. 2. Total development area = 44.5 ± acres. 3. Total number of lots = 4. 4. Total number of principal dwelling units = 4. Note: Guest homes will be allowed in accordance with the County's Special Use Permit process. 5. Total area of proposed non-residential floor space = none. 6. Total number of individual dwelling units proposed for each structure = 1. 7. Total number of proposed off street parking spaces - each home must provide a minimum of four off street parking spaces. 8. Total proposed density = 1 dwelling unit/11.2 acres. 7/25 X 6400 „ +6289 - -............... ...-.,.- VICINITY MAP A PORTION OF CARBONDALE QUADRANGLE SCALE: 1" = 2000' EXHIBIT "A" 6700 5700-- 6675 5650 N8914.09 -W .. ... .. 7. .962.58:.' 6584t2' SKETCH PLAN HAMMES -SUBDIVISION A PARCEL OF LAND SITUATED IN THE SOUTH HALF OF SECTION 24, TOWNSHIP 7 SOUTH, RANGE 88 WEST OF THE 6TH PRINCIPAL MERIDIAN • 'EXtSTINC SEPTIC FIELD AREA-. 714 -ACRES +/'- • -'. i,".. .

EXHIBIT B c i n 0 3 0. 84 PROJECT NO. 97046.01 SHEET OF PHASING The project is not proposed to be phased. DRAINAGE No definite drainage channels exist, as this parcel is currently in its native condition. Due to the site's topography of a mild ridge running east west through the middle portion of the site, no off-site storm or snowmelt runoff affects the site. The lack of off-site runoff decreases the amount of grading necessary for the roadway and actual building areas and thus reduces erosion and drainage issues. Detention is not proposed for this development because of the large lot sizes allowing natural diffusion of minor flows generated from proposed site improvements. The added impervious area would be only be a few percent of the sites' total area. The diffuse flows would make routing of flows to detention areas difficult and the construction of channels and ponds would disturb more area and cause more erosion than warranted by any benefit gained. In general, erosion control should consist of disturbing as little existing vegetation as possible and, therefore, minimizing reclamation. It is anticipated that areas that must be disturbed will be seeded with a grass mix recommended by the Soil Conservation Service. WATER SUPPLY SYSTEM The Subdivision's domestic water needs will be served by either an individual well for each dwelling unit, or by a lesser number of wells with appropriate well sharing agreements. Currently, there is one existing well providing an adequate water supply to the existing residence. Quantity testing was performed on this well in 1991 and indicated that the well produced a firm yield of fifteen (15) gallons per minute with acceptable drawdown. The applicant will supply the County with more current well testing data in connection with an application for preliminary plan approval. One or more additional wells will be drilled to provide potable water for the new lots within the proposed subdivision. Representatives of the applicant have conferred with the Basalt Water Conservancy District and have confirmed that the property is within the area approved in the existing Basalt Water Conservancy District's Substitute Supply Plan. The applicant will enter into an appropriate contract with the Basalt Water Conservancy District to provide a legal supply of water to the proposed wells and will operate under the District's established Substitute Supply Plan until completion of any necessary augmentation case. The applicant shall have the appropriate Basalt Water Conservancy District contract in place prior to approval of preliminary plan. WASTEWATER TREATMENT Sewage disposal will be by individual sewage disposal systems (ISDS), typically septic tanks and leach fields for each dwelling. Sizing and design of systems will be in accordance with Garfield County and Colorado State regulations in effect at the time of construction. With one ISDS apparently operating properly and the SCS soils information, there are strong indications that the remaining three sites will have acceptable percolation rates for conventional soil absorption systems. Responsibility for construction, operation and maintenance of individual disposal systems will rest with the individual lot owners, who should maintain the systems in accordance with Garfield County Health Department regulations. GEOLOGIC HAZARDS There are no known geologic or radiation hazards on the site. There is no regulated floodplain on the site. UTILITIES Utilities are already available to the site including electricity from Holy Cross Electric and telephone service from US West Communications. Extensions can easily be made to service each proposed lot. As mentioned above, domestic water will be provided from on-site wells, and sewage treatment will be through individual sewage disposal systems. ACCESS The proposed Hammes Subdivision has existing legal access over an existing roadway to a County Road. Prior to 1975, the Hammes property was part of a larger tract of land owned by Rimledge Uranium and Mining Corporation. On December 24, 1975 Rimledge conveyed a portion of its property lying between the Hammes property and the County Road to one Alan Storey (copy of deed provided in Appendix D). Thereafter, on March 16, 1976 Rimledge conveyed to one Diane Dale the property that is now the Hammes property (copy of deed provided in Appendix D). These documents both refer to a non-exclusive access easement from the County Road to the described property. Thereafter Storey expressly conveyed to Dale a non-exclusive easement for access across the Storey property (copy of deed provided in Appendix D). These access rights are appurtenant to the Hammes property and demonstrate the necessary legal access thereto.

COUNTY OF GARFIELD STATE OF COLORADO APPENDIX B SOIL CONSERVATION SERVICE MAPS AND DESCRIPTIONS 1 Soil Survey kuited to hay and pasture. Grasses and legumes grow well if adequate fertilizer is used. If properly managed, le unit can produce 4 tons of irrigated grass hay per cre annually. This unit is well suited to alfalfa and small grain rps. It is limited mainly by the slope in some areas. iting tillage during seedbed preparation and controlling weeds help to control runoff and erosion. All illage should be on the contour or across the slope. If roperly managed, the unit can produce 75 bushels of arley per acre annually. The potential plant community on this unit is mainly 'uestern wheatgrass, needleandthread, prairie negrass, mountain big sagebrush, and Douglas rabbitbrush. Other plants that characterize this site are uttongrass, Letterman needlegrass, common nowberry, Utah serviceberry, and antelope bitterbrush. he average annual production of air-dry vegetation is about 1,500 pounds per acre. If the range condition eteriorates, mountain big sagebrush, Kentucky luegrass, Douglas rabbitbrush, and annual weeds increase in abundance. These plants are dominant hen the range is in poor condition; therefore, livestock razing should be managed so that the desired balance of the preferred species is maintained. I This unit is suited to homesite development. The ain limitations are the shrink -swell potential and the ope. The shrink -swell potential can be minimized by prewetting foundation areas. The slope is a inanagement concern if septic tank absorption fields are stalled. Absorption lines should be installed on the contour.

Other plants that characterize this site are Letterman needlegrass, elk sedge, mountain snowberry, and big bluegrass. The average annual production of air-dry vegetation is about 2,000 pounds per acre. If the range condition deteriorates, Gambel oak, mountain snowberry, Kentucky bluegrass, and annual weeds increase in abundance. Range seeding may be needed if the range is in poor condition. This unit is poorly suited to homesite development. The main limitations are the shrink -swell potential and the slope. The effects of shrinking and swelling can be reduced by maintaining a constant moisture content around the foundation. Backfilling excavations with material that has a low shrink -swell potential can also reduce the effects of shrinking and swelling. This map unit is in capability subclass VIIe, nonirrigated. It is in the Brushy Loam range site. 54—Grotte gravelly loam, 25 to 65 percent slopes. This deep, well drained soil is on mountainsides. It formed in alluvium and colluvium derived dominantly from sandstone. Elevation is 6,000 to 8,000 feet. The average annual precipitation is 15 to 17 inches, the average annual air temperature is 35 to 38 degrees F, and the average frost -free period is 80 to 105 days. Typically, the surface layer is grayish brown gravelly loam about 4 inches thick. The next layer is gravelly clay loam about 3 inches thick. The substratum to a depth of 60 inches or more is very channery clay loam. The soil is calcareous throughout. Included in this unit are small areas of Dahlquist and Southace soils. Included areas make up about 15 percent of the total acreage. Permeability is moderately slow in the Grotte soil. Available water capacity is moderate. The effective rooting depth is 60 inches or more. Runoff is rapid, and the hazard of water erosion is moderate or severe on the steeper slopes. This unit is used as rangeland or as wildlife habitat. The potential plant community is mainly Indian ricegrass, bluebunch wheatgrass, bottlebrush squirreltail, true mountainmahogany, Wyoming big sagebrush, and Utah serviceberry. Other plants that characterize this site are Douglas rabbitbrush, needleandthread, prairie junegrass, pinyon pine, and Utah juniper. The average annual production of air-dry vegetation is about 600 pounds per acre. If the range condition deteriorates, Douglas rabbitbrush, Wyoming big sagebrush, cheatgrass, and annual weeds increase in abundance. Loss of the surface layer severely reduces the ability of the unit to produce plants suitable for grazing. This unit is poorly suited to homesite development. Soil c The main limitation is the slope.
