The issues that follow are based on the conditions of CUP 1476 and may form the basis for discussions with the applicant and conditions of approval. In recognition of the short timeframes involved with the Highway 12& 18 construction project, staff is prepared to meet with the applicant immediately to address these outstanding issues. 1. The applicant will have to submit an erosion control plan approved by the County Land / Conservation Department and receive an erosion control permit from the Zoning Division /of? rr T before earthmoving activities can begin. 2. A determination should be made by the Zoning Division as to whether special exception permits will be required. If required,the applicant will have to seek approval from the Board ?c-jG,. of Adjustments before earthmoving could take place within 300 feet of any navigable streams. • 3. To accommodate the Town's recommendation that the permitted area be reduced from 50 acres to 15 acres,more specific information from the town and a new legal description will be necessary. 4. Where the project is visible from the road or from neighboring residences,berming or landscaping should be considered to reduce the visual impact of the project. 5. Standard restrictions on dust and noise mitigation should be incorporated,particularly given that blasting is contemplated. Information should also be provided about any crushing, washing or screening that will take place on site. Appropriate mitigation efforts include site spraying as necessary,incorporating spray bars on equipment,delineating and graveling all drive aisles, and requiring mufflers on equipment. The applicant should consider paving perhaps 50 feet of the drive atthe entryway,which would be consistent with past CUP approvals. 6. Closure of operations should be linked with completion of the highway project, or to explicit beginning and ending dates. 7. The applicant should consider phasing extraction activities and reclamation so that a — ,11 rT minimum amount of area is open a t a n y one time. In past approvals f o r larger sites,the •' .a P Committee has required that applicants follow a phasing plan such that a maximum of 10 to t 20 acres is open at one time. Phasing may suggest that fencing could be somewhat portable, relocated to different portions of the site as necessary. 8. The applicant should indicate the sources,quantity,and disposition of any water to be used in - '- extraction and processing, including whether pumping will be required. 9. The ZNR Committee should consider requiring that the applicant improve the intersection of CTH N and the proposed driveway access, if in the determination of Highway staff that such improvement is required. The applicant should contact the Highway and Transportation Department regarding the appropriate location of the CTH N access, and scheduling of Transportation Committee action on that opening. 10.A performance bond should be posted to guarantee mitigation and reclamation measures are fully implemented. c �� > ! �ti � � 5
