BOOK 94 FArUE87 *Specific Reasons for the Appeal At the January 12th Planning and Zoning Commission meeting, attorney O'Haire expressed concerns about the proposed sand mine. Those concerns related to water impacts, traffic, aesthetics and compatibility. All of the issues raised by attorney O'Haire are addressed by the county's LDRs, and staff and the Planning and Zoning Commission considered these issues in their review of the project. Despite requests from staff, as of the writing of this report, Mr. O'Haire has provided no data or specific information to support his appeal generally or to support specific concerns or specific reasons for his appeal. 1. Water impacts. Although no paved surfaces are proposed, stormwater aspects of the site plan have been reviewed by county engineering staff and by the St. Johns River Water Management District (SJRWMD). The SJRWMD has issued a stormwater permit (see attachment #5) and county engineering will issue a county stormwater permit as soon as the applicant documents to county engineering that the submittal to St. John's is the same as the submittal reviewed by the county. Thus, SJRWMD and county stormwater regulations have been satisfied by the proposal. These regulations require that projects provide adequate stormwater treatment and retention/detention as well as avoid or mitigate stormwater impacts on surrounding properties. Section 934.05(5) of the "Excavation and Mining" chapter of the county's LDRs states that mining projects shall have "... no significant adverse off-site impact on groundwater quality or groundwater levels". As stated in staff's report to the Planning and Zoning Commission, county staff do not have the expertise to evaluate groundwater impacts. Therefore, county staff relies on the expertise of the SJRWMD and the St. John's review and permitting process. Since St. John's has reviewed and issued a permit for hydraulic dredging on-site (see attachment #6), staff concludes that a mining operation in accordance with the St. John's permit would have no significant adverse off-site impact on groundwater quality or groundwater levels. Therefore, the proposed project, as permitted, meets the Chapter 934 groundwater requirements. According to the St. John's permit, a monitoring well, monthly sampling, and reporting to St. John's on a bi-annual basis (January and July), are all conditions of the permit. 2. Traffic Impacts. County traffic engineering staff have reviewed the site plan and a traffic impact statement prepared for the applicant. This review focused on project impacts in terms of the volume of trips generated/attracted by the project and the capacity of the existing road system. It is estimated that the project will generate/ attract 108 daily trip ends and 13 peak hour trip ends that will primarily impact 82nd Avenue and Oslo Road. The county's traffic concurrency system indicates that the affected segments of 82nd Avenue and Oslo Road can handle from 370 to 578 additional peak hour trip ends and still function at an acceptable level of service. Therefore, staff anticipates that the project would use up less than 4% of the remaining available capacity on any affected segment of 82nd Avenue or Oslo Road. At the direction of the Planning and Zoning Commission, traffic engineering also evaluated the type of vehicles (sand trucks) that will be using 5th Street S.W. and 82nd Avenue. After review of the application, traffic engineering staff 40 March 14, 1995
