71-35u PLANNING STAFF RECOMMENDATIONS for USE PERMIT REQUESTS to be heard by the CHESTERFIELD COUNTY BOARD OF SUPERVISORS Wednesday, 13 Oct. 1971 71-35U Warren Bros. Co. Clover Hill Magisterial District Tax Map Sec. 77, lot 36 This parcel is now zoned Agricultural (A) as are all adjacent parcels. This request is for a Use Permit to carry on a quarrying operation. The applicant has made a request for the rezoning of the subject parcel to the Industrial classification. The Planning Commission has recommended denial of this request and it will come before the Board on the 13th. The applicant has submitted the following plan of operation and extrac- tion as required by Sec.' 17-11(F) of the County Code: "PLAN OF OPERATION FOR EXTRACTION OF MATERIAL AND QUARRYING OPERATIONS As required by Section 17-11 (f) the following plan of operation is respectfully submitted: 1. The operating hours as set forth in Section 17-11 (i), 7:00 a.m. to 9:00 p.m. shall be complied with, although applicant would like to be able to operate two shifts at this location, be- ginning at 6:00 a.m. and running until 12:00 p.m. In the event that this schedule cannot be granted under the current ordinance applicant will comply with such hours of operation as may be deter- mined by the Board to be appropriate. 2. The asphalt plant dust, odor and noise control methods will satisfy all governmental requirements with dust and air pollution units installed and a dry air system which will eliminate the necessity for using settling ponds. Since our plant would be mainly enclosed, there should be no noise factor with this operation. 3. The quarry dust would be controlled by keeping all pit roads damp with a water truck utilizin~ a spray system. 4. All rock crushers would have dust devices installed with water, chemical, fog and/or suction systems with dust collectors. The screens will have water or chemical for dust control. All material transfer points will have water or chemical fog systems and hoods. 5. We contemplate leaving a rather dense screen of natural growth around the perimeter of the operation which would aid in eliminating any noise that may be generated from our operations. In addition, noise can be controlled by using enclosed structures over the main parts of our plant operations. The equipment pro- ducing noise of any consequence would be primarily the Jaw crusher, scalping screen, cone crusher, finishing screens and conveyors. A Jaw crusher covered with a removal house for major repairs would be the most economical and should effectively eliminate noise. A -1- large structure covering the primary feeder and scalping screen can be used. Scalping screens may also be covered with a rubber covered punched or screen cloth. Conveyors themselves produce very little noise, rather it is the transfer of material from one conveyor to another that frequently produces same. All transfer points can be lined with rubber liners to eliminate this noise if a problem occurs therefrom~ 6. Noise and dust from our operation should have no adverse affect on any adjoining property owner, first due to the screening of woods around the perimeter of the operation, the above referenced use of structures, rubber insulation on noise producing transfer points combined with the use of water or chemical fog should produce a plant that will be quiet, clean and safe. The only other item of noise that should result from our operation would be quarry blasting. All blasting would be restricted to the daYtime hours, With all shots to be wired using multi-second delays wired in dequence to minimize shock. Stemming would be a minimum of 5' (five feet) to control rock throwin~, dust and noise. We would propose to notify any ad- Joining property owners that may be in close proximity to our opera- tion at least one hour before a shot is scheduled in order that no-one would be surprised at the blast. 7. Access to our operation will be as marked on the attached plat made by LaPrade Bros., dated July 2, 1971. 8. The nearest property owner to our proposed operation would be Mr. and Mrs. Linwood Belcher who are the owners of the site and from whom we propose to lease the property. Property owners located across Swift Creek will be protected by 100 feet or more of woods along the creek. 9. All overburden or waste material will be used to form a dike or bank along Swift Creek 100 feet behind the creek and between Swift Creek and the operating site thereby forming an additional barrier from our operation. 10. Since we propose moving our entire Richmond area operation onto this site, we would hope that the period of time for our opera- tion would be indefinite as substantial capital improvements will be made to the site and our contract with the present property owner provides for the initial period of the lease to be ten (10)years with two (2) additional ten (10) year renewal options granted. ll. We propose to construct buildings for equipment repair, consisting of repair areas, a welding shop, paint shop, storage, a scale house for asphalt plant and crushing plant use, a powder storage house, a spare parts storage building, an office building to house the general headquarters for the Richmond District operations of Warren Brothers Company. 12. Restoration of the property will be accomolished within two (2) years after the cessation of operations and can be accomplished by either of the following two methods, or such other reasonable re- quirement as the Board deems appropriate: -2- A. Upon the cessation of operations, the site will be cleaned of all machinery and foreign material and graded to provide natural drainage. The previously stripped and stockpiled topsoil would then be spread over the regraded area and seeded. All slopes will have a maximum of a 2:1 slope. The pit will be allowed to fill with water creating a pond with natural surroundings. B. Upon cessation of operations, all machinery and foreign material will be removed. All areas with the exception of the pit will be graded to provide drainage, covered with topsoil and seeded. The pit would then be fenced off and provided with two gates for access. A sanitary land fill operation could then be put into use by the County. The remainder of the overburden and topsoil could be used for cover material in the land fill. Upon completion of the land fill operation the property could be available for any number of uses. 13. The State Mining Commission will require a Reclamation Plan and a bond to be furnished prior to commencement of any operation on this property to insure a reasonable reclamation. We would trust that this bond would be sufficient, however, should any additional reason- able security be required we will be glad to furnish same.

Gutknecht, District President" Staff feels that, though now undeveloped, this area will, in the not too distant future, experience residential growth potential. There- fore, this particular parcel might presently be used for the quarrying operation but it is Felt that such an operation should be limited not only in time but also in scope.
