direct~d to address the location of the low permeability barrier and map its specific location in the Operations Plan Ms. Schulz said there had been a lot of groundwater testimony submitted into the record. She expressed her belief that the conflict could be minimized by the construction of the low permeability barrier. In response to a question from Ms. Colbath regarding whether there had been other instances of similar barriers being used, Ms. Schulz said there had not. She said the applicant had made his casein the record regarding how the barrier would function. . Mr. Dignam clarified that a low p.ermeability barrier had not been seen in Lane County. He said it was his recollection that the technique had been used successfully elsewhere. He stressed that this was a relevant fact and asked staff if there are other places this teclmology is used. There was general consensus to table the item until a future meeting so staff could review the record for specific examples of the technology being used in other areas of the country and address the issues raised by the commission. . Traffic Ms. Schulz said staff had accepted and waived the applicant's requirement to' conduct a traffic impact analysis because the level of change of traffic on the roads would not rise to a level of significance. In response to a question from Mr. Belcher regarding concerns raised by the City Traffic Engineer, Mr. Yeiter said gravel permits had a ,life expectancy and truck traffic was worked in to that expectancy. He . said the streets used were 'scheduled for improvements. He acknowledged that in the future the area would be more developed and there could be an issue in 20-30 years. Ms. Colbath. commented that the City was not sure what the long term plan was going to be for the roads/intersections and there was some movement to the idea of incremental impact and development paying its share for road improvements in the area. Mr. Yeiter said the concern was that there would be more difficulty in the future when traffic levels . increased due to future development if Delta was still operating at that time. Ms. Schulz said the level of change in traffic did not rise to the threshold where the applicant was required to do further analysis. She noted that road improvements would be done in the future to increase traffic capacity in' the area. Mr. Zdzienicki said the projected growth in traffic was 1 percent. He said the current operating permit allowed 2 million tons per year and Delta was currently close to that limit so there would not be significant truck traffic added. Mr. Belcher commented that it would be unfair to penalize Deita for any future growth and development in the area. He remarked that the City concern was not valid. Mr. Duncan said he supported the staff conclusion. MINUTES-Lane County Planning Commission. . July. 25,.2006' . . Page 16.
