146 <br /> <br /> Mr. Toscano suggested that the public hearing and first reading of the ordinance <br />be held on October 1st when Mr. Cox can be present. <br /> <br />PRESENTATION: FUTURE WATER SUPPLY <br /> <br /> Mr. Gene Potter with the Rivanna Water and Sewer Authority, invited Mr. <br />Hawkins, who spoke during matters by the public, to call him as he is not aware of any <br />water quality problems in the area. Mr. Potter said that five alternatives are being <br />recommended for implementation now which they hope will bring supply and demand <br />into balance by 2050: modify release t~om South Fork Rivanna reservoir in the event of <br />a drought; implement a demand management plan in the event of a drought; water <br />conservation; add a 4' crest control to the South Fork Rivanna dam; and siltation control. <br /> <br /> Mr. Lynch praised the report, and asked if there is some way to get an indication <br />of what the siltation is as disposal costs vary depending on this. <br /> <br /> Mr. Potter said corings have been done to classify the type of material to identify <br />where it is coming from, but there is no toxicity data, though he doubts there is a <br />problem. Mr. Potter said that if dredging is favored more work would need to be done. <br /> <br /> Mr. Lynch asked if an attempt has been made to correlate sedimentation increase <br />with development, and Mr. Potter said no. <br /> <br /> Ms. Richards expressed concern that the construction phase of the Route 29 <br />Bypass could increase sediment, but noted that the consultant did not feel this is a <br />probterrr <br /> <br /> Mr. Potter said that it is recommended that VDOT be required to do something <br />beyond their normal control in order to ensure no sedimentation increase. <br /> <br /> Mr. Caravati asked if we are getting better at predicting future demand, and Mr. <br />Potter said that growth predictions were higher in Albemarle County than has occurred, <br />and the newer predictions are based on what has happened in the last thirty years. <br /> <br /> Ms. Richards said that the League of Women Voters is studying the water supply <br />issue, but there seemed to be a lack of information in their newsletter, and she suggested <br />Mr. Potter make a.presentation to them. <br /> <br />REPORT: WATER CONSERVATION UPDATE <br /> <br /> Mr. Brad Humphreys, Water Conservation Program Coordinator, reviewed water <br />conservation accomplishments for FY 00-01, including holding a contest to develop a <br />slogan for water conservation; conducting a leak detection survey; and receiving a grant <br />to retrofit plumbing fixtures in low and moderate owner-occupied residences. Mr. <br />Humphreys said a water audit of City facilities will also be done. <br /> <br />Mr. Lynch applauded the plans for the water audit. <br /> <br /> Mr. Toscano asked if the Albemarle County Service Authority's differential <br />pricing for water is having an impact on their usage, but Mr. Humphreys said he does not <br />know. <br /> <br /> Mr. O'Connell said the Authority's primary target with the differential prices is to <br />discourage summer watering. Mr. O'Connell said staff are looking at general policy <br />recommendations regarding the rate structure. <br /> <br /> Ms. Richards asked if there are any federal or state programs that reward <br />successful water systems, but Mr. Humphreys said he has not found any such programs. <br /> <br /> Mr. Lynch said it is important to keep in mind that saving water might not save <br />money on water bills, but the long-term implications are pretty significant to taxpayers. <br /> <br /> <br />
