BOX 62, HEREFORD, CO. 80732 Gentlemen, We have prepared this report to evaluate the septic systems on the "Strunk" property, which lies 1 mile Southeast of Hereford, Colorado. The total pro- perty contains 1550 Acres, more or less, and is located in Section 35, Town- ship 12 North, Range 62 West of the 6th P.M. , Weld County, Colorado. The property contains two houses. The "Ranch House" was built in 1920 and. contains 2 bedrooms. The new home was built in 1950 and contains 3 bedrooms. Each unit has its own septic system. The Strunks propose to use the extra bedrooms as a "Bed & Breakfast" business. This evaluation is to see of the existing septic systems are adequate for this use. The Soil Conservation Service soils map and information for this area is attached. It shows that the underlying soils at the location of the improve- ments is Ascalon, fine sandy loam, 0 to 6% slopes. This soil is shown to have a moderate permeability rate. The Strunks obtained the services of a septic system installer who helped determine the location and size of the septic systems. The inspection also determined that each system was well constructed and in good working order. For analysis, a sewage flow rate of 60 gallons per person per day will be used. 961100 Weld County Health Department June 11 , 1996 Environmental Health Services PROJECT NO. 96144 RE: INDIVIDUAL SEWAGE DISPOSAL SYSTEM USR #1117 SHARON STRUNK (66354 WCR 390) P.O.

Based on the above information and calculations, it is my judgement that the existing Individual Sewage Disposal System for each house will meet the require- ments of the Weld County Health Department and are suitable for the proposed use as a "Bed & Breakfast" facility. The 3-bedroom house will be at 100% of the design. Therefore, care should be taken in the use and maintenance of the system and frequent observations made to determine that the system is workinan mje l• , Respectfully, .t4-...

The main soils on the subject are as follows : #1 Altvan fine sandy loam, 0-6% slopes is a deep well drained soil on smooth to moderately dissected plains. The soil formed in calcareous gravelly alluvium. *4 Ascalon fine sandy loam, 0-6% slopes is a deep, well drained soil on smooth to moderately dissected plains . The soil formed in calcareous loamy alluvium. *11 Badlands soil consists of gently sloping to steep areas dissected by many intermittent channels that are entrenched in calcareous soft silt stone, soft claystone, and fine-grained sandstone. *12 Bankard loamy fine sand, 0-3% slopes is a deep, well drained to somewhat excessively drained soil on flood plains . The soil formed in stratified calcareous sandy alluvium. #27 Epping silt loam, 0-9% slopes is a shallow, well drained soil on slightly dissected to highly dissected plains . The soil formed in calcareous loamy residuum derived from silt stone. #29 Haverson loam, 0-3% slopes 3s deep, well drained on flood plains and adjacent stream terraces . The soil formed in stratified, calcareous, loamy alluvium. #32 Kim-Mitchell complex, 6-9% slopes is deep, well drained and formed in calcareous loamy alluvium and colluvium. #44 deny fine sandy loam, 0-6% slopes is a deep, well drained soil on smooth to moderately dissected plains . The soil formed in calcareous loamy alluvium. #51 Peetz gravelly sandy loam, 5-20% slopes is deep, somewhat excessively drained soil on back slopes and shoulders of moderately to highly dissected uplands ridges and breaks. The soil formed in calcareous gravelly alluvium. The slopes on this soil are convex. #73 Vona sandy loam, 0-3% slopes is deep well drained on smooth to slightly dissected plains . The soil formed in calcareous sandy alluvial and eolian material. The dominant soils are identified above. Generally the soils are deep and well-drained to moderately drained, on 0-10% slopes, nearly level to gently rolling to undulating, that formed from calcareous sandy/loamy alluvium and eolian material, mainly from sedimentary cock. They are usually light brownish-gray or light-brown loams, consisting of fine sandy loams to gravelly sandy loams that can be very sandy on the bottom lands and may consist of finer sands in even lower areas . Permeability is rated moderately rapid to rapid. Effective rooting depth is 10 to 60 inches or more, depending on the depth to bedrock. The available water capacity is high to medium, and natural fertility is low to medium. Wind erosion is raided as moderate to slight, the hazard of soil blowing is slight . Runoff is rated from slow to medium and the hazard of soil erosion is slight to moderate. 961100 The native grasses a ipical for this altitude and . aainly bunch grasses, Prairie Sandreed, Needle and Thread, Blue Grama, Sideoats Grama and Western Wheatgrass, Thread Leaf Sedge, Fringed Sagewort and other annual and perennial grasses, forbs and sedges . Production of forage in the pasture is considered average, as there are no areas of excessively steep hillsides or badlands.4 Because of proper soil management and the good vegetative characteristic of the ranch, it can be rated as not having a severe wind erosion problem, even with the existence of high winds during part of the year.
