Compliance with Chapter 23 of the Weld County Code has been met as evidenced by the attached resolution, which was approved by the Board of County Commissioners on November 20, 2002. Although Weld County and the City of Greeley do not have an intergovernmental agreement the Cities growth plan does show a conversion from agricultural to residential uses. 2. The land is designated at both "Prime" and"irrigated land, not prime"by the USDA SCS. As the site is only 23.2 acres in size it is not of a viable size to farm. 3. North Weld County Water District will serve the site. A signed water service agreement has been submitted with the final plat that includes fire district references. 4. Individual Sewage Disposal Systems will provide sewer provisions to the lots. ISDS will be permitted and adhere to Weld County requirements. 5. N/A 6. The subdivision street will adhere to Weld County requirements which are detailed in the road plans submitted with the final plat application. 7. N/A 8. The covenants for Buxman Estates require that the individual landowners are responsible for issues affecting the interior subdivision road. 9. As evidenced by the vicinity map the subdivision is not contiguous with another subdivision or unincorporated townsite. 10. Due to the large lot sizes, parking on the public road should not be an issue. 11. The only access to WCR 29 will be from Sunshine Lane. 12. Subdivision lots will not have direct access to WCR 29 and will only access Sunshine Lane. 13. The final drainage plan submitted with the final plat addresses adequate drainage and stormwater facilities. 14. The maximum number of lots in the subdivision is 8. 15. All public service districts have reviewed the application through the sketch plan phase to the final plat phase and their concerns, if any, have been addressed. 16. As the site is only 23.2 acres in size, there will not be an adverse effect on the outlined entities. In addition various referral agencies have reviewed this application in each phase and have not raised any issues which have not already been addressed. SUMMARY OF CONCERNS IDENTIFIED DURING SKETCH PLAN APPLICATION PROCESS 1. The Office of the State Engineer, Division of Water Resources, in their referral stated that insufficient evidence has been provided to show that the proposed water supply can be provided without causing injury to existing water rights. The Office of the State Engineer indicated that it would need more detailed information regarding the irrigation water distribution system that would transfer water from the existing irrigation holding pond. The proposed irrigation system pumping water to the individual lots has been abandoned. The holding ponds are stormwater and irrigation tail water runoff ponds. The storm water pond for the adjacent property Is an evaporation system. Water is released from the west tail water pond to ditches, which transfer it to the Poudre River. 2. The Weld County Department of Public Health and Environment indicated that due to soil conditions,the applicant should have a site evaluation (percolation test and a logged profile pit/hole to 10 feet) conducted on each of the lots in the approximate location of each septic system. See attached test results. The engineer has suggested that results look favorable for Septic system designs. 3. The Weld County Department of Public Works stated in their referral that Sunshine Lane be indicated as two 12' lanes(paved)with 4'gravel shoulders on the Change of Zone Plat. Indicated as such on Plat. ,.� 4. The Weld County Department of Public Works indicated that Weld County Road 29 is not paved and that traffic counts will exceed 200 with the proposed lots,which is a level at which fugitive dust is a concern. The applicant is required to enter into an agreement with the County to proportionately share the cost of paving WCR 29. The applicant will enter Into an agreement with the County to will escrow, upon sales of each lot, 35% of the costs to pave WCR 29 across the frontage of the subdivision and Lot A of RE 2339 north to Highway 392. The proposed agreement between the County and the applicants will be binding for a period of 10 years. If at that time the County has not paved WCR 29, the escrowed funds will be reimbursed to the applicants. See attached letter of a proposed agreement with Weld County. 5. The Weld County Sheriffs Office indicated a concern that there is no secondary access road into the subdivision. The applicant has been directed by the Weld County Department of Public Works to have only one access to WCR 29. 6. The Weld County Department of Public Works indicated concerns with the proposed relocation of the existing swale and combining irrigation and storm water detention within the existing irrigation ponds that are located off-site. Drainage information addressing the 100-year storm and the limits of inundation showing all structures one foot above the 100-year storm flow elevation should be shown on the final plat. The relocation of the existing swale plans has been abandoned. The drainage swale will remain in it's current location and tall water from surrounding fields will continue to flow through the ditch as it exists. The drainage plan has been modified to show this condition and address the 100-year flood contours. 4 7. The Eaton Fire Protection District indicated that the developer will need to coordinate with the North Weld County Water District in regards to the spotting of the fire hydrants. Fire hydrant locations are indicated on the plat. 8. Future submittals shall include the delineation of utility easements on each lot as required. Indicated as such on plat. 9. The Weld County Department of Public Works has required that all landscaping in the intersection sight distance triangles be less than 3.5 feet high at maturity. Indicated as such on plat. 10. The Weld County Planning Staff has indicated that the applicant address how the impact of eight residential lots would be compatible with existing surrounding land uses including the neighboring use by right Buxman Dairy operation and a cattle feedlot operation for up to 100 head located in the east 14 of the SE 1/4 of Section 21 T6N R66W. The Buxman family owns the dairy and cattle operations. k will be their responsibility to satisfy the complaints from the same homeowners to whom they will be selling lots. The covenants will allow small animal ownership and maintenance on the subdivision lots. The character of the subdivision will be agriculture and FFA,county fair or other animal raising needs. The Plat contains "Weld County's Right to Farm"statements describing the hazards of living in the country. Potential homebuyers will be able to read and understand the liabilities of buying and living in rural agriculture surroundings. it is the intent of the Buxman's to continue the use of Best Management Practices at the Dairy to mitigate potential problems with odors and pests. It is In their best interest to make the surrounding environment compatible with the development that they are proposing. They will continue to participate in the Home Owner's Association and maintenance of the street and access roads keeping them in constant communication with the lot owners. There is a proposed development property less than one mile to the East of this subdivision. The Poudre Ridge development will include Industrial/Commercial, single family residential, multifamily residential,elementary school and neighborhood center sites. The developers have requested that the City of Greeley consider the property location for inclusion in the Mid-range Expected Growth Area. When developed, the City of Greeley municipal services will be extended to with a mile or less of the Buxman property. The Buxman property is currently within the City of Greeley's Municipal Area of Influence. The Buxman's are aware of and sensitive to the encroaching developments and the potential for future environmental conflicts. Developing their own lots will help them to maintain a neighboring relationship compatible with residential estate properties. 11. The intent of"Weld County's Right to Farm"shall be incorporated into the Buxman Estates covenants. Indicated in covenants to be submitted with the Final Plat. 12. The City of Greeley has indicated that the proposal does not comply with the Greeley 2020 Comprehensive Plan. The development is located within the City of Greeley's Municipal Area of Influence and 20+ year, Long Range expected Growth Area. Therefore, policies within the City of Greeley Comprehensive Plan apply. However,the development of urban scale lots is not feasible at this 5 time because of the lack of municipal services. Residential Estate zoning is the appropriate use of the land until municipal boundaries and municipal services are extended. Most of the concerns of the City of Greeley can be addressed at a later date when these services are extended into these areas. The City's referral has suggested that the development is an example of"urban sprawl,"however, the development is on the northern edge of the Long Range expected Growth Area and it would be good planning practice to merge high density lots with county"Agriculture"zoned property by separating them with larger"Residential Estate" development. 13. The applicant shall include a copy of an agreement with the properties mineral owners, stipulating that the oil and gas activities have adequately been incorporated into the design of the site. A copy of the agreement with the mineral owners is included. Access roads to well heads are being protected with easements through the northern two lots of the proposed subdivision (Lot B)and through Amended Lot C. Agreements currently do not include locations of specific easements. 14. The applicant shall indicate building envelopes on proposed Lots that are outside of the 150-foot setback from the existing wellhead and the 200-foot setback for the existing tank battery on the property. Indicated on plat. 15. A completed improvements Agreement addressing road construction and maintenance,landscaping and maintenance,utility extension,signage,and any other applicable elements of the minor subdivision shall be submitted for review and approval prior to the Final Plat. Will be completed prior to Final Plat. 16. The West Greeley Soil Conservation District recommends that the applicant does an on site soils test prior to any construction. Soils tests for Individual lots will be required as per the District's recommendation and written into the covenants. 17. The State of Colorado Department of Natural Resources,Geological Survey recommends that lot-specific geotechnical investigations determine foundation designs, include foundation perimeter drains on each lot, and ISDS design be engineered depending on measured percolation rates. Soils tests will be required and foundation perimeter drains will be installed on each lot. The required tests and drains will be described in the subdivision covenants. 18. After reviewing the Minor Subdivision Sketch Plan proposal, it is the opinion of the Department of Planning Services staff that the Minor Subdivision Sketch Plan proposal fails to comply with the Weld County Code for the reasons identified above. The concerns from each of the referral agencies has been addressed and corrected as requested. The lot drainage problems associated with water rights have been removed from the revised Plat. The concerns of the State Engineer that the applicant did not demonstrate that the proposed water supply can be supplied from the holding ponds will no longer be a factor In the design of the eight lots. The applicants have demonstrated that the proposal will be compatible with the surrounding land uses and they will control through a covenant all of the 6 required design and maintenance needs. The applicants have demonstrated the desire to develop to the strict standards of the County and provide a needed land use of the quality and detail needed. Therefore, we respectfully request that Weld County's Planning Staff, agencies and Boards approve the request for a Change of Zone of the Buxman property. 7 r • BUXMAN ESTATES SUBDIVISION DECLARATION OF COVENANTS, CONDITIONS & RESTRICTIONS THIS DECLARATION made and executed this day of -, by names of parties involved as owners of , located in the Buxman Estates Subdivision, according to the recorded plat thereof, Weld County, Colorado.

The rural areas of Weld County may be open and spacious, but they are intensively used for agriculture. Persons moving into a rural area must recognize and accept there are drawbacks, including conflicts with longstanding agricultural practices and a lower level of services than in town. Along with the drawbacks come the incentives which attract urban dwellers to relocate to rural areas; open views, spaciousness, wildlife, lack of city noise and congestion, and the rural Buxman Estates Covenants 4 atmosphere and way of life. Without neighboring farms, those features which attract urban dwellers to rural Weld County would quickly be gone forever. Agricultural users of the land should not be expected to change their long- established agricultural practices to accommodate the intrusions of urban users into a rural area. Well run agricultural activities will generate off-site impacts, including noise from tractors and equipment' slow-moving farm vehicles on rural roads; dust from animal pens, field work, harvest, and gravel roads; odor from animal confinement, silage, and manure; smoke from ditch burning; flies and mosquitoes; and the use of pesticides and fertilizers in the fields, including the use of aerial spraying. Ditches and reservoirs cannot simply be moved out of the way of residential development without threatening the efficient delivery of irrigation to fields which is essential to farm production. Section 35-3.5-102, C.R.S., provides that an agricultural operation shall not be found to be a public or private nuisance if the agricultural operation alleged to be a nuisance employs methods or practices that are commonly or reasonably associated with agricultural production. Weld County covers a land area of over 4,000 square miles in size (twice the State of Delaware) with more than 3,700 miles of state and county roads outside of municipalities. The sheer magnitude of the area to be served stretches available resources. Law enforcement is based on responses to complaints more than on patrols of the county and the distances which must be traveled may delay all emergency responses, including law enforcement, ambulance, and fire. Fire protection is usually provided by volunteers who must leave their jobs and families to respond to emergencies. County gravel roads, no matter how often they are bladed, will not provide the same kind of surface expected from a paved road. Snow removal priorities mean that roads from subdivisions to arterials may not be cleared for several days after a major snowstorm. Snow removal for roads within subdivisions are of the lowest priority for public works or may be the private responsibility of the homeowners. Services in rural areas, in many cases, will no be equivalent to municipal services. Rural dwellers must, by necessity, be more self-sufficient than urban dwellers. Children are exposed to different hazards in the county than in an urban or suburban setting. Farm equipment and oil field equipment, ponds and irrigation ditches, electrical power for pumps and center pivot operations, high-speed traffic, sand burs, puncture vines, territorial farm dogs, and livestock present real threats to children. Controlling children's activities is important, not only for their safety, but also for the protection of the farmer's livelihood. Parents are responsible for their children.

This letter also acts as an addendum to my previously submitted Storm Drainage Report dated January 27,2003. Most of your comments concern items that need to be included on the Change of Zone Plat. These inclusions have been made. Attached is an updated Drainage Layout drawing showing the location of cross sections utilized for figuring the 100-year flow elevations. Also attached are 100-year flow elevations calculation sheets and the corresponding cross section profiles. These attachments should address your comments concerning the cross sections. r^ While figuring the 100-year flow for Buxman Estates,no intercept amount was utilized for Greeley No.2 Canal. The entire 100-year flow was figured to pass the canal with no interruption,therefore making the flow calculations conservative. It is also my understanding,after a discussion with a former FEMA employee who used to do floodplains determinations,that when calculating the 100- year flood flows the flow is assumed to pass roads,ditches,etc.without interruption. If you have any questions or need further information,please call. Sincerely, o%pp0 RED/ST cam W' o•• ; • 39 : It-r`r/ONAL Eric WfiD . .
