6 ORDINANCE f. : “AN ORDINANCE AMENDING AND REORDAINING ARTICLE I (IN GENERAL) ARTICLE II (EROSION AND SEDIMENT CONTROL) OF CHAPTER 10 (WATER PROTECTION) TO COMPLY WITH STATE nd REQUIREMENTS FOR EROSION AND SEDIMENT CONTROL” (2 reading) ORDINANCE g. : “AN ORDINANCE AMENDING AND REORDAINING SECTIONS 34-61, 34-62, 34-64 and 34-1200 OF CHAPTER 34 (ZONING) OF THE CODE OF THE CITY OF CHARLOTTESVILLE RELATING TO CONDITIONAL nd ZONING” (2reading) PUBLIC HEARING/REPORT : WATER SUPPLY PLAN Mr. Tom Frederick, Executive Director of the Rivanna Water and Sewer Authority, said that this has been a lengthy and complex process. He reviewed the history of the water supply efforts. He said he is certain that the approved project will be permitted. He said the plan balances the ecological needs with the needs for water. He said numerous public meetings have been held. Mr. Lynch asked Mr. Frederick to speak to the cost, how it will be paid for, and how it will be phased in. Mr. Frederick said that a public meeting was held in September regarding phasing. He said the options are: build the Ragged Mountain dam and pipeline all at once (most expensive); build the dam in phases and build the pipeline in the first phase; build the Ragged Mountain dam now and defer and phase in the remainder. He said the $37 million would be financed by debt service. He said the cost share agreement is being negotiated between the City and Albemarle County staff. He said Rivanna is not a direct party in the negotiations. He said the entire 50 year plan is estimated to cost $142 million, but he noted that this looks at all aspects of the water supply and treatment, including aging infrastructure, and is not solely for growth. Mr. Lynch said that a bladder was explored in 2002, and while it would have been cheaper it was not allowed. He noted that RWSA’s budget has increased even with the City water use declining. He asked what infrastructure has been replaced in the last five years. Mr. Frederick said a line at the University has been replaced, and funds have been used for planning and design. Responding to a question from Mr. Taliaferro, Mr. Frederick said that dredging was found to be more expensive and was set aside as an alternative. Mr. Lynch asked what happens to the reservoir if it completely silts up. Mr. Frederick said maintenance is not always the most prudent thing to do when the cost outweighs the initial investment. He said he believes that eventually equilibrium at the reservoir will be achieved, but it will be a smaller body of water. He said sedimentation needs to be prevented. Ms. Hamilton said she has heard that the cost of dredging is prohibitive, but she said she has never seen the numbers. She also asked about the Shadwell Quarry. Mr. Frederick said he has asked for an update from the 2004 numbers, but dredging down to bedrock was estimated to cost between $200 million and $225 million depending on disposal. He said it could be done over a period of years. He said he has no detailed information on the Shadwell Quarry and no study has been done. He said only a cursory look at it has been taken. He said some initial concerns are that the water quality is better in the western part of the county, and it would take significant piping to access the Quarry. He said the Rivanna River is designated scenic in that area and scenic rivers cannot have reservoirs.
