MOHAVE COUNTY RECORDEf 04/10/97 08:59A PAGE 1 OF 4 MOHAVE COUNTY BOARD OF SUPERVISORS RECORDING FEE 0.00 RESOLUTION NO. 97-124 A RESOLUTION SETTING FORTH A REPORT OF WATER SUPPLY INADEOUACY FOR THE PRELIMINARY SUBDIVISION PLAN FOR SILVERADO ACRE ESTATES, UNIT 1, TRACT 3805, BEING A SUBDIVISION OF PARCELS 1 THROUGH 7 AND PARCEL 9 THROUGH 13 OF SILVERADO ESTATES, AS SHOWN ON PARCEL PLAT, BOOK 2, PAGE 93, IN A PORTION OF SECTION 17, TOWNSHIP 20 NORTH, RANGE 13 WEST, IN THE MOHAVE COUNTY GENERAL AREA, MOHA VE COUNTY, ARIZONA. WHEREAS, at the regular meeting of the Mohave County Board of Supervisors held on April 7, 1997, a public hearing was conducted to determine whether a Report of Water Supply Inadequacy from the Arizona Department of Water Resources for the above described subdivision should be accepted by Mohave County as requested by Leo Homer, Silver Ranch Corporation, of Phoenix, Arizona. The engineering firm of record is Consulting Land Surveyors and Engineers of Scottsdale, Arizona, and WHEREAS, the property is located approximately 20 miles southeast of the City of Kingman. The land is accessed via eastbound Interstate 40, then south 4.5 miles on u.S. Highway 93, then northwest one mile along Old Highway 93 to the site, and WHEREAS, the Preliminary Plan was approved on February 18, 1997, via BOS Resolution No. 97- 50. Condition number 3 of the resolution requires the developer to provide a report on the adequacy of the water supply from the Arizona Department of Water Resources (ADWR). Silverado Acre Estates requested and has received a report of water supply inadequacy, and WHEREAS, Article 4.6-1 of the Mohave County Subdivision Regulations states: "The developer shall submit plans for the subdivision water supply, regardless oflot size, to the Arizona Water Commission (ADWR) in accordance with the provisions of ARS 45-513." A report from ADWR on the adequacy of the water supply for the subdivision will be required prior to the approval of the final plat. In the event the Preliminary Plan for the subdivision has been approved conditionally to the receipt of a report from the ADWR and such report states that the developer has not demonstrated that the water supply is adequate to meet the future needs of the subdivision, the matter shall be referred back to the Planning Commission and Board of Supervisors for further evaluation. The developer may submit additional information in the form of reports prepared by qualified hydrologists, geologists, or engineers regarding the adequacy for the water supply for consideration during this re-evaluation, and . . RESOLUTION NO. 97-124 PAGE 2 OF 4 BK 2882 PG 948 FEE~9718216 Page 2 WHEREAS, water adequacy determinations consider the quantitative availability of the water supply and the economic feasibility of reaching and maintaining that supply. The department considers wells deeper than those depths specified prohibitively expensive and impractical, and WHEREAS, subdivisions relying on domestic wells are considered "dry lot". ADWR will not issue a statement of water adequacy if the depth to water is more than 400 feet. Further, a statement of inadequacy is issued if depth to water cannot be sustained at 400 feet or less for a period of 100 years, and WHEREAS, when reviewing subdivisions relying on domestic wells, ADWR considers the total number of lots proposed. It is not usually feasible for a well to be drilled on each lot in a subdivision containing hundreds. Since water adequacy must be demonstrated for each and every lot, a statement of inadequacy can be expected for such proposals, and WHEREAS, subdivisions relying on community water, or water companies, are considered to have adequate water supplies if the water supply is 1000 feet or less and that water supply can be sustained at 1000 feet or less for 100 years, and WHEREAS, the Board of Supervisors, after receiving a recommendation from the Planning and Zoning Commission, has accepted two statements of water inadequacy in the past year. Both of the subdivisions were categorized as Rural Development Area in the General Plan. The first was for Sawmill Creek, a subdivision of 13 one-acre and five-acre lots. The developer drilled domestic wells to water on each of the one-acre lots and provided a quality analysis for each lot, and WHEREAS, the second statement of inadequacy was accepted for Greenwood Village, a subdivision consisting of213 five-acre lots. The Planning Commission and Board accepted a statement of water inadequacy because the lot size was five acres or greater and the subdivision was in the Rural Development Area. Residents living in the area could expect a more rural lifestyle, and WHEREAS, the developer's engineer has provided this department with information on one well in the same section as the subdivision but not within it. The well was 422 feet deep and provided flows between 70 gpm and 95 gpm. A second well in an adjacent section reached water at 220 feet and provided 15 gpm. Information has been provided on other wells in the same Township and Range by the developer; this information is attached as Exhibit A, and WHEREAS, Silverado Acre Estates is a subdivision of 339 one-acre lots and it is categorized as Suburban Development Area. The developer has provided information on 15 wells drilled within the same Township and Range as the subdivision. The wells range in depth from 35 feet to 550 feet and provide flow rates ranging from 15 gpm to 1100 gpm, and WHEREAS, the well data indicates that there is water at varying depths and that the wells are capable of providing sufficient water for a single-family dwelling. The well data is not sufficient to indicate the stability of the water table or the effect of hundreds of domestic wells on that water table, and , . . PAGE 3 OF 4 6 BK 2882 PG 949 FEE~971821 RESOLUTION NO. 97-124 Page 3 WHEREAS, the following described Findings of Fact are for the above captioned item: 1. The Arizona Department of Water Resources has issued a report of water supply inadequacy for Silverado Acre Estates Subdivision. 2. To obtain a statement of water adequacy, the developer has to provide a central water supply or demonstrate water adequacy on each and every lot being created. 3. The well information provided is insufficient to determine sufficient water supply. The information indicates that the water table within the same section as the subdivision is approximately 400-450 feet deep. The flow rates indicate enough flow to support some single family dwellings. 4. The well information provided is insufficient to determine the long-term effect of pumping 100 or more wells. WHEREAS, at the public hearing before the Mohave County Planning and Zoning Commission on March 12, 1997, the Commission recommended that the Board of Supervisors ACCEPT the statement of water inadequacy as submitted, and WHEREAS, the notice of hearing was published in The Standard, a newspaper of general circulation in Kingman, Mohave County, Arizona, March 22, 1997, and posted on March 21, 1997, as required by Arizona Revised Statutes and the Mohave County Zoning Regulations. NOW THEREFORE BE IT RESOLVED, that the Board of Supervisors, at their regular meeting on Monday, April 7, 1997, ACCEPTED the statement of water inadequacy as recommended by the Mohave County Planning and Zoning Commission and outlined herein.
