BOX 1229 BERTHOUD, COLORADO 80513 TOWN HALL (970) 532-2643 February 12, 1997 Shani Eastin, Current Planner Department of Planning Services 1400 N. 17th Avenue Greeley, Colorado 80631 RE: Little Thompson Valley Estates POLICE DEPARTMENT (970) 532-2611 Dear Shani, The Town of Berthoud is writing to you today in regards to the proposed Little Thompson Valley Estates. The Town has submitted two letters to you dated August 6, 1996 and September 24, 1996 to the Planning Department expressing our concerns and questions with the compatibility of this use with the uses on the surrounding properties. The Town Board reviewed this proposal at its February 11th meeting and voted to send a recommendation of denial to Weld County for the following reasons: 1) The type of development in this area does not meet our requirements for "Rural Development Clusters." Rural Development Clusters would have required at least 30% of the site to be dedicated as common open space; located in areas classified as non -prime farmlands; clustering by ofa domestic water system and municipal waste water system, or on site package plant; of the development in order to provide pry iion of space, or other common common open space; ol and contain some common unifying element, such as a park, open s Pa re. 2) The placement of the building envelop on lot 1 is not in keeping with the intent of preserving the agricultural uses of this property. The building envelop on lot 1 should not be located away from the other lots and should be located adjacent to the other building sites in order to preserve as much land as possible for future agricultural uses. 3) The Town Board questions whether the Berthoud Area Fire Protection district will allow a cul-de-sac of this length without some other entrance or access point. Weld Ccunw Planning Dept. FEB 1 41997 F�' 4) The Town has recently annexed to within 1 mile of this site and will be providing waste water service to this area within the next year. If development is to occur we would request that they connect to this system and not use individual septic systems. We would hope that these recommendations could be incorporated into this proposal and allow for the preservation of this site. We would like to thank you for the opportunity to review this proposal and for your time and consideration of our concerns.

Long Dlvlsion Director Vicki Cowart State Geologist and Director Dear Ms. Eastin: In response to your request and in accordance with Senate Bill 35 (1972) I visited this property to review the plat. Landmark Engineering collected three soil samples in April 1996 for pavement design, but none of the raw data was included in their letter report. The site consists of low hills that slope northward toward the Little Thompson River. Water was observed flowing into a north -south trending depression that is present in the southwestern part of the property. 1) Soil. The onsite soils have been identified by the Soil Conservation Service as Weld and Colby. They have a high clay content, but are generally not problematical as a building substrate with the following caveats: Weld soils are described as having a high shrink/swell potential in the 8 -15 -inch interval and are also characterized as having low strength. Therefore, I recommend that a geotechnical sample be collected from the subsurface soils at each building envelope and analyzed for strength and swell/consolidation characteristics. This information will be useful in building design. If necessary, unacceptable native soils can be excavated and replaced with an engineered fill. Numerous angular cobble -sized sandstone fragments were observed during the site inspection, and bedrock is present in the banks of the above -mentioned depression. The bedrock is mapped as the upper transition member of the Pierre Formation. Foundations should be placed on homogeneous material, i.e., not a combination of soil and bedrock, to prevent differential settlement problems. 2) Surface drainage. The final plat should show the flood plain limits of the Little Thompson River. No construction can take place within these limits. The plat should also indicate the depression with a 15-20 foot setback as a no -build zone. Swales should be avoided for siting homes and leach fields because of the potential for flooding or water accumulation. Little Thompson Valley Estates, p.2 3) Subsurface drainage. I visited the site on a warm day when snow was melting and observed the ground surface to be very muddy and drainage to be slow. The shallow bedrock has lower permeability than the soil and will further decrease the rate of water infiltration, and may even cause water to pond on top of the bedrock and in surface depressions. I strongly recommend that foundation drains be considered in building design to help prevent problems associated with groundwater accumulation. The shallow bedrock and clayey soil present special problems for septic systems. Even leach field areas where percolation rates are found to be acceptable may be subject to premature failure because of ponding of water on the bedrock surface. This issue needs to be thoroughly investigated before construction begins. It may be necessary to install engineered systems. In summary, development of the site should proceed only with a better understanding of the subsurface conditions. Potential sites for leach fields should be located, and within these areas, depth to bedrock should be determined and percolation tests performed. If problematical conditions are encountered, suggestions for engineered systems should be proposed. Please contact me if I can be of further assistance.

Greetings: Thank you for allowing the Larimer County Planning Department the opportunity to review the final plan of the Little Thompson Valley Estates PUD. The proposed subdivision is about three miles east of the Larimer/Weld county line, and about four miles east of the trom the Town of Berthoud. Provided that the PUD is developed as planned, it will not result in any significant negative Impacts on Larimer County's facilities, services or environment. If you have any additional questions or concerns, please feel free to contact me at 970.498.7694 or tasmandp@co.larimer.co.us. Sincerely, Dan Tasman Planner II 4 PRINTED ON RECYCLED PAPER 01/15/97 13:51 TX/RX NO.6054 P.001 • January 22, 1996 SUBJECT: Little Thompson Valley Estates In regards to Item 12, none of the White pines will do well in this area. The site is also not conducive to growing Blue spruce. However, Rocky Mountain Juniper, Eastern red cedar, Ponderosa pine, Austrian pine and Scotch pine are all good choices for conifers. One of the maps show that alfalfa will be grown on part of the property. In order to grow alfalfa the amount of water needed is approximately 30" for the growing season. With natural precipitation during a "dry" year a net irrigation requirement of 26" is needed. For a "normal" year a net irrigation requirement of 25" is needed. 25 acres of alfalfa would require approximately 62.5 acre feet of irrigation water. The plan did not state if the property has an irrigation water right. If not, native grasses would be a better choice for planting. Erosion control measures should consider use of surface roughening, mulching, vegetative cover and early application of gravel base on areas to be paved. Sediment control measures are site specific and could include buffer strips, sediment fence, dikes, sediment traps or basins. We hope that these observations are useful to the applicant. Hello
