Mr. Doug Sears, representing the applicant, presented the cases. John Hall commented _on the concerns of the Health Department regarding the septic system. The applicant and the Board discussed said concerns. Robert Bechtholflt, an adjacent landowner, presented a petition signed by neighbors bordering the Allison Farm Subdivision. Said petition protested the proposed RV parking area in the ₹relief that such a parking area is not in keeping with the standards already set by the surrounding area. Several adjacent landowners were present and voiced their objections to these requests. (Tape change 79-142) Doug Sears responded and answered the objections raised. After _deliberation, Commissioner Steinmark made a notion to accept the recommendation of the Planning Commission and approved the Change of Zone from A to E, based on - the fact that said change would be compatible with the surrounding land uses, that it appears that adequate water and sewer service can be made avail-able, further that the development standards are accepted. Commissioner Dunbar seconded the motion and it carried unanimously. Commissioner Dunbar made a notion to grant the Change of Zone from A to H including the develognent standards.

At such time as the City of Greeley sewer service is available the issuance of septic system permits will cease ; and under #2 include d) She designs for mains and laterals be shown on the final plat and construction costs be included in the improvements agreement.

This matter is scheduled for hearing by your beard at 2:00 P.M. on November 7, 1979. The preliminary plans for this rezoning have been approved by the City Planning Commission and Weld County Planning Commission over certain objections by surrounding residents of Highland Hills and Westridge. In their decision process they also ignored the objections and recommendations made by the Weld County Health Department. Due to the high water level and solid sandstone formations underlying the proposed develop- ment the Health Department dyes not approve the use of septic tanks. The Health Department feels the only safe and sanitary way fnr disposal of the waste water and sewage is through the use of the normal Greeley city sewer disposal system. This centralized sewer system should be available for hookup by this proposed subdivision within the next few months. The Health Department is also against locating the R.V. Storage Area next to the gas pumping station currently located on the property. The Health Department study and recommendations have been made a part of the Allison Farm rezoning package for your review in making your final decision. We have personally contacted a majority of the property owners who presently live in the western portion of Highland Hills and without exception they have expressed their -epnosition to locat- ing an R.V. storage lot (eventually resulting as a sore eye) along the west side of 59th Avenue not only because of the reasons put forth by the Health Department but also due to the depreciating effect this would have on nearby residential property. With the current high-type development (Aims College, Family Sports Center, Skating Rink) in the vicinity of West 20th Street and 59th Avenue along with the increased traffic antics- 7' pated, requiring subsequent upgrading of these traffic routes, we feel any R.V. storage 1st approved for construction should be located en the back side of the development, or at least net along side of a main traffic artery like 59th Avenue. Your sincere review of all the facts available and unbiased spin en 'when making your final decision will be greatly appreciated.

(i- .1 (`-.. , , ,u I' i r:: : My Cornmissik.n expires AuquS1 10, 1°' ALLISON FARM Re-zoning and Subdivision Application Statements It is our feeling that while the policies of the Weld County Com- prehensive Planning do not contemplate the type use proposed in our sub- division, the changing conditions of the area clearly demonstrate both a -demand on the part of the public as well as a need for Allison Farm as herein proposed. Since the time of adoption of both the Greeley Com- prehensive Planning and the Weld County Comprehensive Planning, there has been re-zoning and/or substantial new construction within the im- mediate area of Allison Farm, i .e. , Westridge Subdivision, Bird Sub- division, Knaus Subdivision, Hiland Knolls. Several of these consist of one (1) acre tracts served by septic systems designed for single family residential use. Allison Farm contemplates that each property owner shall construct and maintain his/her own sewage-septic system; however, the layout of utility easements lends itself to these property owners being able to connect with central Greeley sewer services, at such time in the future that such services are available should the pro- perty owners so desire. This is especially true in the requested multi- family zone where it is proposed that a package septic system shall be constructed and maintained to handle the affluent discharged from this Area, said system to be constructed in a logical and accessible location thereby minimizing the expense should it be deemed necessary to tie in to central sewage services. It should be pointed out here that at this time, the City of Greeley does not intend to serve this area with pub- lic sewage services until 1984 at the earliest. It would seem to us that the changing factors of this area would dictate growth and devel - opment before 1984. The aforementioned subdivisions are presently served by the City of Greeley water or Central Weld Water. Allison Farm can and will be served by City of Greeley water services. Also, all said subdivisions do not have or intend to construct curb, gutters and sidewalks. The -economics of the development of 20,000 square foot lots, or greater, does not lend itself to providing these improvements and the size of said lots Allows retention of run-off water to be kept on individual lots. The construction of paved streets in Allison Farm will be in total compliance with County specifications. In view of all the factors mentioned herein, we feel that Allison Farm is both timely and well suited for the location. The fact that there are two (2) subdivisions with the same basic concept as Allison Farm, contiguous to this property, would suggest that the proposed 20,000 square foot lots, or greater, are compatible with the surrounding areas. The proposed multi-family area located on the west portion of Allison Farm has been designed and coordinated to blend in with the larger lots in the subdivision. As Greeley continues to grow to the West, (with the present Greeley City limits being little more than one (1) mile east of this site at the time of this application) more and more multi -family/higher density areas will be requested. Highland Hills presently has approximately fifty multi-family residences within one mile of this site. 0Ur application represents a natural trend and demand toward this type of use. Further, it should be pointed out that the land uses in the immediate area are becoming more varied as our community' s growing population expands to the west. ARIS, Greeley Family Sports Center, Geriatrics, Alms Community College, and the proposed skating rink support this trend of changing land use. In summary, we feel that Allison Farm is an exciting, compatible, and well planned development. ALLISON FARM P.U.D. DEVELOPMENT ST-ANDARDS 1 .

The areas in question are made up of the following soil types: Olney fine sandy loam, 1 to 3 percent slopes (21B-B) : This is a prime farmland soil when under irrigation. This soil makes up approximately ten percent of the area. This soil is not considered high potential if not irrigated. Otero sandy loam, 1 to 3 percent slopes (53-B) and Otero sandy loam, 3 to 5 percent slopes (53-C) : These are prime farmland soils when under irrigation. When not under irrigation, they are not considered high potential cropland. They make up approximately 75 percent of the des- cribed area. Nelson fine sandy loam, 3 to 9 percent slopes (53M-CD) : This is not prime irrigated farmland nor high potential non-irrigated cropland. This soil makes up about ten percent of the described area. It is a moderately deep soil with sandstone within 20 to 40 inches of the surface. Loup-Boel loamy sands, 0 to 3 percent slopes (49-AB) : This is a deep, poorly drained soil found on stream bottoms and along drainageways. They typically are found with water tables ranging from the soil surface to 24 to 36 inches in depth. This soil is not prime irrigated farmland nor is it high potential non-irrigated farmland. This soil, and the Aquolls and Aquents soil, make up approximately five percent of the area. Aquolls and Aquents, flooded (34-U) : These are nearly level soils on smooth plains in depressions and along bottoms of natural drainageways. They are deep, poorly drained soils that are usually subject to excessive runoff and a water table at or near the surface in the spring and during the peak irrigation season. WI; x Page 2 - Zoning Changes - Sears and Company Realtors Soil Interpretation for Building Sites: Slight to no problems: Olney fine sandy loam and Otero sandy loam, 1 through 5 percent slopes. Dwellings without basements: Nelson fine sandy loam has a moderate limitation due to potential shallow depth to sandstone. Dwellings with basements: Nelson fine sandy loam has a severe limitation due to possible depth of sandstone ranging from 20 to 40 inches. Loup-Boel and Aquolls and Aquent soils are severely limited to building site development due to wetness and possible flooding. Septic tank absorption systems can be installed in Olney and Otero soils with slight to no problems. Nelson, Loup-Boel and Aquolls and Aquents soils are severely limited for this purpose due to shallow depth to consolidated rock, or the presence of a water table and flooding, respectively. I feel the zoning change should be considered with the previous comments in mind. The developer should provide information as to how these problems can be resolved or show that the concerns do not exist. Once this is done, I would recommend the rezoning request be granted. ly, onald D.

These applications indicate that sewage disposal will be accomplished 'by individual on-lot systems for both the estate and high density areas. Geologic conditions possibly could influence the suitability of such a disposal method. We feel that various methods of sewage disposal should be evaluated for the development because of the large parcel size and the high density of development. This evaluation should consider "hooking-up" to an established sewage disposal district, construction of a central sewage disposal facility, and the development of an operation and maintenance program. Until alternate methods of sewage disposal have been evaluated and a system for sewage disposal formulated, we recommend that this land not be rezoned. Sincerely, Walter R.
