Received: 7/t0/ O 2: O]PM; 303]BBBOSa ~~ PREEO SILVERMAN GREEN; Pape 4 JUL-IO-2000 02:09PL1 FR04-PLA~ DIVISION-ARAPANOE COUNTY 30379660 T-SiB P.004/015 F-617 special review (USR). It is staffs opinion that the proposed sand and topsoil operations comply with these uses thereby requiring the USR process. The entire property is 320 acres, being the south half of Section 34. The property owner and the Pioneer Sand Company have an agreement that will allow Pioneer to extract sand and fill material from the site in exchange for excavation and leveling services. The operation begins on the western side of the property and proceeds to the east in 50, five (5) to twelve (12) acre increments per year. (See the Site Plan for details) It is estimated that approximately 20,000 to 30,000 bank cubic yards of material will be removed from the site on an annual basis. The operation involves cut and fill to achieve the fnal contours and approximately 5 to 15 feet of material is extracted. The boundaries of the permit area are defined through a metes and bounds description on the Site Plan. The permit area has been reduced to include only the area intended for excavation. The original permit was for 320 acres is being reduced. During the continuation period, an exact acreage with a metes and bounds description will be required and reflected on the plan. Atl associated numerical data wll! be adjusted. The applicant confirmed that six (6) inches of top soil will be replaced on the surface ensuring the productivity of the site. Only limited mobile equipment will be on site during these activities. During the project, a front-end loader, scraper, grader, mobile truck scales, trucks, and light vehicles will be on the property. It is estimated that from 5 to 20, 25 ton trucks will leave and enter the site five days a week, 12 hours a day, from 6 a.m to 6 p.m. The transport activities may be seasonal in nature and may at times be inactive altogether. However, activities are permitted for year round operations. The hours of operation have been reduced to the amount listed above. The adjacent property owners requested the phrase, "6 p.m. or daylight hours, whichever is less." The Zoning Administrator recommends the use of 6 p.m. as the defrned end of day because it is easity enforceable, otherwise, daylight hours are di~cu/t to detrne. A screening operation has been added as part of this proposal and will need to be reviewed further. the screening separates materials as it fitters and piles if far transport. 'The machine is approximately 15 feet square with a conveyor belt and run by a diesel engine. Staff is told most of the water comes from the material itself but some may be added as necessary. The screen is portable with the rest of the operation. As part of the continuation, specifications are required by the applicant, an analysis is required by staff to determine any associated impacts and mitigation measures required. 3
