Lor 7813 Weld County Road 6 Brighton,CO 80601 Department of Planning Services 1555 N. 17th Ave Greeley, CO 80631 Attention to: Weld County Department of Planning Services I am writing to you in response to Case Number USR-1261,concerning the permit for a kennel. I am opposing this proposal due to the fad of the noise that will be caused by the kennel. I chose to live out in the country to be away from noise of any kind and would not like to be disturbed from a kennel. I would also not like to live near a kennel. These are the many reasons why I do not want to see the building of this kennel. Thank you. Sincerely, -111 V Ma K. Lor 2000-0960 jr SCOTT, COX & ASSOCIATES, INC. consulting eng neers • surveyors M. Edward Glassgow, IV, P.E. • William H. Mitzelfeld, P.E. March 23, 2000 Ms. Heather Hathaway 7673 Weld County Road 6 Brighton, Colorado 80601 Project: 00303 Dear Ms. Hathaway: At your request, Ed Glassgow of Scott, Cox & Associates, Inc., has completed research to allow us to address the overall geology of the property located in the S 1/z of the SE 1/4 of Section 20, Township 1 North, Ranch 67 West of the 6th P. M., in Weld County, Colorado. We understand that this parcel is proposed for development as a dog kennel. The available geologic mapping shows the site to have a mantle of surficial soils of Quaternary age (relatively recent), which are eolian (wind deposited). These surficial soils (which we anticipate to be 5 to 20 feet thick, from investigations that we have completed in the area) are shown to be underlain by units of the Laramie Formation. The Laramie Formation is of Cretaceous age and is the geologic unit that contains the coal deposits, which were w=dely mined in Boulder and Weld Counties. The Laramie Formation consists of claystone, sandstone, siltstone, carbonaceous shale and coal. While the Laramie Formation is not as infamous in reputation as the Pierre Shale, as the source of the bentonitic, expansive soils problems that have caused tremendous damage to structures along the Front Range, there are some areas of extremely expansive 'laystones that have been identified within this unit. From a pure geologic standpoint, the site is considered to be stable. The geologic mapping does not show any faults on the site. In fact, the closest mapped faults are approximately 1/2 mile from this site (please see the Subsidence Hazard Map, Figure 1, attached). Please note that the dark diagonal line through the study area, on this illustration, represents the boundary of the Boulder - Weld County coal field and not a fault. EXHIBIT I 9-;3 1530 55th Street. • Boulder, Colorado 8031)3 • (3031 444-3051 • Fax: (3031 444-3387 Serving Colorado with offices in•Boulder• Longmont•Loveland Project 00303 Page 2 The geological literature does not relate the potential for any mineral deposits that are currently of economic significance other than gas and oil. The available coal mining studies document that there has not been any coal mining in the area of this property. However, even if there is some coal deposits that might underlie this property, it is doubtful that a combination of circumstances would ever allow mining, with plentiful, shallow and cheap coal nearby in Wyoming. The only significant geologic concern on this site is the potential for building related problems due to the presence of the potentially expansive claystone within the Laramie Formation and possible daughter soils related to weathering of the claystone. Following are the possible building related concerns... 1 . The Laramie Formation bedrock and any clay daughter sails that result from direct weathering of the claystone may have significant expansive potential. There are well known engineering and building techniques that will assure that the structures on this site perform satisfactorily It is possible, even probable, that the structures will have to be founded on drilled piers. It is possible that the residences will require structural floor systems. The necessary precautions may be very location specific and may related directly to the type and thickness of the mantle of soil atop the bedrock, the depth of excavation and the engineering properties of the bedrock units encountered at the location. It is very important that sufficient geotechnical investigation be completed to define the location specific soils conditions. This will allow the appropriate foundation type and slab/structural floor recommendation to be made. 2. We would anticipate that percolation rates on this site may be widely variable, ranging from very good, where the mantle of eoiian soils are present, to very poor, where daughter soils or bedrock units are present. It is unlikely that the site soils and geologic conditions will not allow a septic system to be constructed. There are many septic system design and construction techniques that will allow the satisfactory design, construction and use of a septic system. As previously discussed, the available mapping shows that this property has not been undermined by previous coal mining activities. Attached to this letter is an illustration that details the risk associated with the study area (Subsidence Potential Map, Figure 1). Project 00303 Page 3 This illustration shows the subsidence potential at this site as assigned based on a study conducted by Amuedo and Ivy for the Colorado Geologica. Survey in 1975 ("Ground Subsidence and Land-Use Considerations Over Coal Mines in the Boulder-Weld County Coal Field"). For the purposes of the A sruedo and Ivy study, criterions were developed to classify the subsidence Dotential. The potential was assigned based on the extent of mining, the depth of cover to the mined coal unit and the depth of the mined coal unit. Historically, these classifications have proven to be relatively conservative. This st ady assigns the property as having no subsidence potential, with the closest area of any significant subsidence potential almost a mile away from the study area. In summary, the site geology is relatively simple, consisting of a mantle of wind deposited soil, atop relatively shallow bedrock units. Our resear:h has revealed potential subsidence from coal mining as being of no concern co acern. There is some additional concern related to the potential expansivity and low permeability of some of the bedrock units and the daughter soils from the weathering of these rock units. However, these problems are widespread along the front-range and there are engineering and construction sol ations that can allow the satisfactory construction of buildings and septic systems under these geologic and soils conditions. Thank you for consulting with us. If you have any questions concerning our site inspection, our review of the available geologic information or this report, please do not hesitate to contact us.

When we purchased the property in September 1998 the previous owners had left quite a lot of debris. The debris was piled near the garage, behind the barn and in the field east of the house. Most of the trash was fencing, farm equipment, car parts, pipes, tires, and furniture. We gathered all the trash together and separated it into piles so that we could dispose of it. We have taken over 6000 lbs. of trash to the dump, over 3500 lbs. metal to be recycled, and 40 tires to be recycled. We still have about 20(O lbs. of metal and approximately 15 tires to be removed. We expect to have the remaining debris removed by the end of this summer. I am enclosing pictures showing the property when we moved in, and pictures taken on April 3, 2000. I am also enclosing a receipt showing the metal we have removed for recycling. The appliance that was in the driveway when you visited was removed that same afternoon. It had been placed there for a friend of ours to pick up. You list that there are 2 dogs on the property. Currently we have 3 dogs, an Australian Shepherd, a Border Collie, and a Toy Poodle. I hope that this addresses any concerns. If you have any questions please contact me. Sincerely, „so /� c Heather L. Hathaway EXHIBIT :FY '.a • rig + , b.rr x tiu.
