~ III IIIIIIIIIIIIIIII Road & Bridge Memo Date: 4/15/98 To: Jim Komatinsky, Development Dept. From: Rick Ullorq Road & Bridge Supervisor RE: Special Use Application 98-8, PC Management ~~~ i Our review of the perrrtit expansion request by PC Management has brought forth some concerns. There may be some issues we have not had adequate time to assess as we received this packet for review on Monday, April ~. Generally, we are concerned with the impact to CR 13. The upper section of the road is seasonal usage wi[hout improvements. The applicant estimates 5 truck loads or ] 0 trips per day to the staging azea. This location is not the same as we understand was approved in the original permit. As the applicant notes on page 3 of their General Project Report, "the county road nartows and the toms tighten just beyond the staging area, their lazge trucks had trouble negotiating the road to reach the proposed staging azea". We agree with this assessment and aze concerned that the county may incur an impact to the road causing an expense to the county for additional improvements and/or repair on this section and beyond. This road is not designed for haul trucks. There is low visibility, narrow width, and structural instability to the seasonal section of this road. Appropria[e signage would be necessary. We are confused by their estmates on quantity of rock to be removed based on the mining area proposed of 125.5 acres. they have estimated rock reserves of 243,870 tons in two slide areas of 7.3 acres. What are the reserves in the other 118.2 aces? At two semi-truck loads of rock per week, only during the non-winter months and non-hunting seasons in the fall would require approximately 193 years to remove the rock from the staging area on CR 13. It seems more likely the truck traffic impact would be much higher than two semi-track loads per week and dictated by the market. =' A' app ~ sea ~~ RIO uf1:1,1:0 v0. JE'vrlOPtdCltf C~~ ` ~~ °F- With the short period of time we have to review this proposal, there is not ample time to put a dollaz amount to the improvements that may be needed. With additional clarification from the applicant, we could accurately estimate this within a few weeks.
