1977-06-16June 16, 1977 (Adjourned from June 15, 1977) An adjourned meeting of the Board of Supervisors of Albemarle County, Virginia was held on June 16, 1977, beginning at 4:00 P.M. in the Board Room of the County Office Building, Charlottesville, Virginia; said meeting being adjourned from June 15, 1977. Present: Mrs. Opal D. David and Messrs. Lindsay G. Dorrier, Jr., Gerald E. Fisher, J. T. Henley, Jr. and F. Anthony Iachetta. Absent: Mr. W. S. Roudabush. Agenda Item No. 1. The meeting was called to order at 4:05~.P.M. by the Chairman who said that Mr. Agnor, the County Executive, was not present at this time since he was working with the consultants on the ordinance for protection of the South Rivanna River Reservoir. Agenda Item No. 2. Discussion: New Physical Education Facilities-Albemarle High Schoo Mr. Fisher said he did not believe the Board of Supervisors would be able to take any action on this request today since they had only received a report from the committee late last night. Mr. Clarence McClure, Superintendent of Schools, said Albemarle High School was built in the 1950's for 1,000 students. The gym is still in use today for twice as many students. The other support facilities of the school have been upgraded over the years. With the exception of locker room space, which was. added in 1970, there have been no additions to the physical education facilities. There are now more students taking physical education and more interest in girl's sports. Until this present year, all tenth graders were our of physical education and health classes for ~a5 days a year taking driver education classes. This gave some relief in the use of the gym. A change in driver education requirements has now changed this pr©cedure. The School Board studied school needs in general and a new physical education facility is their number one priority. Seven architectural firms were interviewed; Robert Vickery and Associates were chosen. A committee made up of administrative staff, students, parents, teachers and School Board members met five times to consider the type of physical eduoation facility that Would meet the needs. That report is before the Board today~. The present facilities are completely inadequate. The facilities also eliminate elective courses for eleventh and twelfth grade students for the present and the near future. Locker space is lacking. The bleachers will only acc0modate about 500 students and these bleachers infringe on the basketball court. The limited number of bleachers discourages attendance at games. University Hall has been used, but, when that is done, the profits from the game are reduced by the cost of the rent for that facility. There is a need for health classes in the section of the building where health and physical education are taught. The committee and the school also feels additional classroom space over the locker r.oom should be considered. Because the facility is overcrowded by students, there is no possibility of extending any use to the community. The facilities being proposed, will offer an opportunity for physical education, intramurals, interscholastics and community use. Ms. Brenda Langdon, Activities Director of Albemarle ~igh School, was next to speak. She presented the following facts to the Board. 1. ~bemarle High School is one of the largest schools in the state of Virginia. In student body size, it ranks in the top ten out of 285 high schools. 2. Albemarle High School will house approximately 2100 students in grades 9-12 nexv year. (2400 projeoted for future years) 3. Albemarle High School will have approximately 1100'- 1150 students in grades nine and ten who are required to take health and physical education. 4. The State Department of Education requires health and physical education to be taught in grades eight, nine, ten and recommends that it be taught in grades eleven and twelve. 5. To offer a comprehensive pro,ram that is necessary for the youth and adults in Albemarle County a facility large enough to accomodate the following is needed: A. Health and physical education for 1150 ninth and~tenth ~grade students and at least 150 of th~ eleventh and twelfth grade students. (Hours of use would be from 9 A.M. Until 3:30 P.M.) B. Intramurals for unknown number of students, grades nine through twelve, who are not able to compete on interscholastic teams. (Hours of use would be from 3:30 'P.M. until 6:00 P.M.) C. Interscholastic sports for approximately 500 students in grades nine through twelve in 19 different sports offered at Albemarle High ~School. (Hours of use would be grom 3:30 P.M. to 6:00 P.M. and some nights from 6:00 P.M. until 10:00 P.M,) D. Community activities for our physically fit minded adults. (Hours of use would be from 6:30 P.M. until 10:00 P.M. at least three nights a week.) An indoor facility for approximately 130 days of the 180 day school year is needed. Next year there will be five classes, three periods each day, and six classes, three periods eacy day, with 35 students in each class. Half of these classes will be in health for approximately 50 days and all these classes will be in physical education for approximately 130 days. If physical education classes for junior and seniors are offered as an elective, this would require more teaching stations. If health and physical education are separated (or the state requires this) this would necessiate more teaching stations. The State Department of Education recommends separation of health and physical education, but they have not yet made it mandatory. June 16, 1977 (Adjourned from June 15, 1977) Mr. Willie Raines, Coordinator of Health and Physical Education, said this year the Stat~ mandated lowering class sizes from 40 to 35 students. This necessitated more teaching statio~ There is a possibility that health and physical education classes will be separated in the future. Title 9 has been cited by the state. This has to do with unequal facilities for boys and girls in interscholastic sports. The girl's locker room is barely adequate for physical education, but is also being used for sport teams. In September, PS-94-142 will go into effect which states that each handicapped child must be offered a program in accordance with his needs. Boys presently have no place to keep their gym equipment, they have a poor shower room and most have to carry their wet clothes and put them in their regular locker. This discourages many from participating. Mr. Raines said he would like to offer a program that is attuned to different situations, different abilities and different needs. This canno~ be done with the present space, at present mostly team sports are offered. Mr. Robert Vickery, the architect, spoke next. He said his firm made a five-week study in conjunction with a 13 person committee. The Committee did not opt for an elaborate progra~ The square footage programs were drawn by his office using State guidelines, the BOCA code, planning manuals and their own professional structural and mechanical consultants. They held the requested space to a minimum. At the first meeting of the committee, two goals were established. 1) This would be a learning and teaching facility, and 2) insofar as possible, it would also be for community athletics. The Committee investigated four areas of concern: 1) Arriving at the correct square footage to satisfy the teaching requirements, 2) the invest~ gation of construction and materials to find the best building system, in other words upkeep, maintenance and energy conservation, 3) to prepare a realistic construction cost estimate, and 4) to conceptually arrive at a diagrammatic building solution which satisfied the two goal In arriving at the square footage, two areas were examined; the playing areas and the teaching stations. It is felt that four new teaching stations will be needed next year becaus Jack Jouett students will move to Albemarle High School. This will cause a 40 percent increase in the number of students required to take physical education. If the state separate physical education and health classes, then health will not be an allowed substitute for physi education. This will increase the need for teaching stations and classrooms. A four teaching station gym can be programmed so that in the late afternoon and through most of the evening, it can be used by the community. It would have separate entrances and could be opened and used without opening the school proper. It could also be maintained for less. This is the reason the committee chose a four teaching station facility. There is also needed a 100 percent increase in locker space. In studying the design of this building, it was found that classrooms could be added on the second floor at this time at a lower cost and without using a.ny additional lanH. The corridor between the two buildings would also serve as a gallery for an overflow area from the gym and where additional physical education and other classes might take place. The Architects did a thorough study of two systems; a pre-engineered building and a concrete block structure with flat trusses and a standard roof. Plain wall surfaces, that could be used bath indoors and outdoors by students and the community were considered, and energy conservation. The advantage of a pre-engineered structure is that is can be built rapidly, but in considering the locker room areas, whi6h are as critical as the playing areas, ~his space will take twelve months to construct. After consideration, the Committee chose a concrete building. The proposed budget shows a 20,000 square foot gymnasium with four teaching stations, fully equipped, at 5450,000; locker room area, $304,000; site work, 516,000; and the addition of classroom teaching gallery at $130,000; making a total cost estimate of $900,000. Mr. Ben Hurt, Principal of Albemarle High School, said in 1953 there were 850 students in the school in grades eight through twelve. In the school year beginning in September 1977, there will be 1,100 students in just the ninth and tenth grades, and they are all required to take physical education. This past year there were~ twenty-four classes, six periods a day, four classes each peiord; two for physical education and two for health. With this anticipate. increase in enrollment, there wilt be a need for six classes each period. This will cause an increase of two additional teaching stations just for health and physical education. To accommodate this increase this past year, classes used for teaching math and study hall were taken for health classrooms. This is being worked out by adding two additional trailers next year. One dressing room, previously used for dramatics, has been taken as a classroom all during the day. Since driver education has been expanded and separated from physical educatio~ agricultural classrooms had to be used for driver education. Also, one teacher's work room was taken and is now used all day for a teaching station. At the present, there are also massed study halls in the auditorium and the cafeteria. Mr. Fisher asked if the projection that health and physical education classes will be separated, has an impact on space and dollars. Mr. McClure said this is just one argument being used for the project. No additional space or dollars has been included for this separation. Mr. Fisher asked if the $900,000 estimate is a bottom line figure, or if there ar other costs not included. Mr. Vickery said this is the construction cost; it does not include architectural fees. The only other cost anticipated is approximately 510,000 to institute a loop road to help bus traffic, but this cost might be included in the 516,000 for site development. Dr. Iachetta said the Board's Committee had questions about what changes might bc needed on the outside of the building and asked what these costs might be. Mr. McClure said only one field would be usurped by this construction. Since Jouett is no longer a high school~ their facilities can be available to the high school for softball or baseball. He did not anticipate constructing an additional field. Mr. Dorrier asked if the proposal called for the construction of the teaching gallery at the same time as the construction of the gym or if it could be added at a later date. Mr. Vickery said it would not be practical to add it above the finished roof at a later date. If classrooms are to be constructed in this location it will need to be done with the other construction. Mrs. David asked if any of the committee members had talked to the Parks Committee, since they are hoping to develop community facilities around Jouett rather than Albemarle. At times there have been discussions about the reconstruction of the tennis courts. Mr. McClure said al June 16, 1977 (Adjourned fr'om June 15, 1977) during the planning stages, the Parks Committee was not involved in the meetings, but they have indicated that Jouett might be one of the places they want to construct recreational facilities. Mrs. Elizabeth Rosenblum, member of the School Board, said the main concern of the Parks Committee was to get the t.ennis courts separated off so they could be reconstructed. The School Board has not considered doing anything to the tennis courts in this program. Dr. Ronald Bauerle said even if it is not mandated by the State, he thinks it is a good idea to separate health facilities for teaching since health classes include sex education classes. He did not feel community use of the facility is a responsibility of the government Mr. Fisher said the gallery space is very expensive, ~32.50 a square foot as opposed to $9.15 a square foot for a concrete building. He asked that the Board's Committee, Mrs. David, Dr. Iachetta, and Mr. Roudabush work with members of the School Board's Committee and the staff on this report and make a recommendation to the Board as soon as possible. Mr. VanFossen, Chairman of the School Board, noted that Dr. Bauerle, Mrs. Rosenblum, and Mrs. Haden were the School Board's Committee and suggested that Dr. Bauerle be the pro tem Chairman to call the next meeting. Not Docketed: Mayor Nancy O'Brien was present and noted resolution adopted by the City Council on May 23, 1977, in re~erence to the South Rivanna River Reservoir. She said that City Council tried to come up with a way the City could share some of the responsibility in the development of standards within the watershed. City Council proposes that the Rivanna Water and Sewer ~uthority b~ requested to hire a person who would be called an Environmental Officer. That person would help develop the regulations needed to protect the reservoir. Those regulations would then be jointly approved by the Board of Supervisors and the City Council. County ordinances should also be amended to require approval by that person so that requirements to protect the reservoir against adverse conditions are checked by a person who has this kind of expertise. City Council recommends that there be a monitoring program establish'ed by the Rivanna Authority which this same person would oversee. The City Attorney has checked this proposal and although the final authority rests with the Board of Supervisors, he does not see any legal problems. City Council also supports a continuation of the present ordinance until such time as permanent regulations are adopted. In addition until the adequacy of these new regulations are proven, City Council suggests some sort of development budget be adopted for the reservoir so that anything gai'ned by use of the ordinance will not be lost through a lot of land changes in the watershed basin. Dr. Iache.tta said he did not think there was time for the Rivanna Water and Sewer Authority to hire such a person relative to drawing the regulations. That is the reason the Board of Supervisors is trying to hire an expert to work on the ordinance and standards. The Board will be creating regulations that have never been put in place before and do not have engineering technology behind them. Mr. Dorrier asked if the Board could not appoint a three-part.y committee to come up with a recommendation on this proposal simultaneously with the Betz study and the permanenv standards. Mr. Fisher said the County Executive and City Manager and George Williams, Executive Director of the Rivanna Authority, are already involved in this question. He said the Board will discuss it further at tonight's meeting. Ak 5:40 P.M. the Board recessed for supper and reconvened at ~:30 P.M. in the Albemarle Courthouse. Agenda Item No. ~. Discussion of an Ordinance for Protection of Public Water Drinking Supply Impound.ments. Mr. Fisher called the meeting to order and said the discussion tonight will be on what type of ordinances can be implemented for protectiOn of the South Fork Rivanna River Reservoir ~nd possibly all reservoirs in Albemarle County. At the meeting held on June 8, the Board received staff reports on the proposed ordinance, and at an earlier meeting had received a draft of the ordinance itself. These documents were submitted to Dr. Thomas Grizzard, who is present tonight to give his reactions. Mr. Agnor said the Board had asked that he contact Dr. Grizzard, who is a member of the faculty at V.P.I., a licensed professional engineer in Virginia, and who also holds bachelor, masters and doctorate degrees in Civil Engineering. He is currently serving as the Director Of the Monitoring Laboratory of the Occoquon Watershed Monitoring Authority. Dr. Grizzard was contacted to see if he had any interest in, and would be available, to assist Albemarle County with the preparation of the ordinance and standards. He replied in the affirmative and a~reed to meet with the Board and discuss his reactions to the Betz Report and the severa items which the staff has prepared. Mr. Agnor then turned the meeting over to Dr. Grizzard. Dr. Grizzard said he had looked over the Betz Report. There are several things that need further clarification. Information on those item's will be included in the data transmittal which Betz is mailing to him. Principally, the thrust of assessing nonpoint sources of pollution depends upon the method of assessment. There are several ways to do this and the quality of the estimate needs to be reviewed in terms of the way the used data was collected by Betz. This would have an effect on the required reduction to render a beneficial effect on the reservoir. One reason why the curre.nt assessment on nonpoint sources might be less than adequate, is that in 1975 there was not much precipitation. His own work in the Occoquon Watershed has been to establish stations in selected drainage areas and then to sample these for a long period of time and during different types of storm densities. He is then able to assess the nonp~int reduction over an entire annual cycle. Dr. Grizzard said there is one other point about the report. It should be pointed out that the Dillon Model used by Betz to arrive at a required reductiOn for nonpoint loading is empirical relationship that has been developed from observations of a number of impounded Waters around the world. Phosphorus loadings have been computed and their eutrophic status has been assessed by sampling in the reservoir. A relationship has been developed that a~!ows comparison of the bodies of water ~eing studied to the loading relationship that has June 16, 1977 (Adjourned from June 15, 1977) been developed from studying a number of other lakes. Dr. Grizzard said he met with staff members this afternoon and they discussed management alternatives ranging from so-called nonstructural types of approaches up to and including structural and physical chemical operations for storm water runoff. At the present time, from an engineering standpoint, physical chemical treatment is the only thing that will provide a certain level of performanc( because pre-construction testing can be~done on runoff water. Such things as street cleaning~ grass waterways and p~rous pavements, are essentially in the experimental stage and are being given trials in this country, Europe and Canada. To be able to design a nonpoint sourc( control program at this time would be difficult. However, structural alternatives are the most expensive, the most extreme and probably more than is required in some instances. Dr. Iachetta asked if Dr. Grizzard had any rough estimated cost for structural control. Dr. Grizzard said no, but it does require land acquisition, capital investments in equipment and operational costs. In the case of chemical treatment, it would require periodic assessme~ of the effectiveness to be sure that the dosages were getting the proper results. Mrs. David said treatment of the water is speaking to the quality of the water. The Board is also concerned about what is happening to the reservoir. Dr. Grizzard said he was speaking in terms of treatment of runoff water before it gets to the reservoir. His point is that this is the only method in which he would have a lot of confidence in the design process. Ail other things he has mentioned are in an experimental stage. Mr. Fisher asked if this kind of treatment for storm water runoff would be a manned operation such as an advanced wastewater treatment plant. Dr. Grizzard said since operation would be intermittent in nature, only operating during periods of runoff, and most likely operating only in the urban area, it is conceivable that it' would be unmanned for a good portion of time having periodic maintenance checks, routine equipment maintenance and routine assessment of the effectiveness with periodic maintenance for removal of collected solids. Mrs. David said this may be feasible in developed areas but she understands that a good bit of storm water runoff is from undeveloped areas; land that is just setting there and eroding. Dr. ~Grizzard said in his operation they have done some base~line monitoring on exclusively forest lands. It does not seem that just forested lands have an excessively high loading factor. They rely on a monitoring approach that involves sampling every storm event during the year and being able to produce a very precise estimate of the pollutant load from a storm event. Mr. Fisher said estimating the load is one thing but trying to reduce it is different. That is what the Board is faced with at this time. Dr. Grizzard Said the Betz report speaks to eliminating a six percent increase over the current nonpoint load from developed or partia] developed areas. Those are types of applications where the so-called nonstructural types of devices are probably going to be the most effective. Yt may be possible to set ration~al goals for quality of drainage water from developed lands. Mr. Fisher said the whole question is one of setting performance standards for runoff and whether to set a base line for a particular watershed or piece of property versus having a universal standard. The use of a base line figure on a particular piece of property that already has a lot of erosion problems might not be a very good base line to use. Dr. Grizzard said the general approach in assessing undeveloped conditions has been to look at site characteristics such as soil, slopes and pre-existing land uses, then to assign a pollutant yield that has been observed from similar soil types and land uses in the same area. This is a justifiable approach to addressing the problem. This question has been addressed in the Betz Report. The technology at this point would require a sampling of every tributary in the watershed or a sampling of specific land use types and then extending those to similar drainage basins in the watershed. Dr. Iachetta said the County is faced with reducing the phosphorus loading to the reservoir by 60 to 80 percent of what is currently entering the reservoir. There is an additional problem in that converting land from a low density use to a high density use multiplies the amount of phosphorus that comes off of that property by a factor of seven. You also get additional things, such as heavy metals, which is a new problem for watersheds. At this time, it seems a structure to catch s~me quantity of the runoff and treat it is the only recognized alternative. Dr. Grizzard said a structural alternative currently provides t? only management plan that can quantify performance. The other less expensive alternatives may have beneficial effects but they are unproven. Mrs. David said there is a comment in the ordinance which says that new developments should be designed so that the post-development storm water runoff does not exceed pre- development conditions. She felt that if the runo.ff from a certain piece of property is already very bad, that would be a poor standard and asked if it were not possible to set a higher standard of performance as a condition of development. Dr. Grizzard said in reading this statement he assumed that "pre-development" could be read as "undeveloped". He said that lake fertilization is a Wholly natural process. It occurs in all lakes and produces a very nutrient poor lake. Mr. Henley asked how long phosphorus remains in a reservoir if it is brought ~n by a flood. Dr. Grizzard said storm flows have varying impacts on an impoundment, depending on how much the reservoir happens to be drawn down when the storm flow enters. If it is drawn way down and there is a lot of available storage, then the nutrient laden waters tend to stay there. A good portion of this material, if it is not flushed out when there is a full reservoir, ends up in the sediment. Under c~rtain conditions it can become available to come back in the water colony an~ stimulate alga~e growth at a later date. One of the'~management alternatives suggested in the Betz Report is aeration in the vicinity of the dam to try and keep oxygen mixed into the bottom waters at that location, thus keeping phosphorus from being released from the bottom waters. This is a proven scheme and has been effective in numerous applications. However that does not address the possibility of phosphorus release in deposite sediments in the upper end of the reservoir. When considering structural control alternatives a storm design for the facility must be made that involves assessment of any damage that will result from being unable to control a Storm with a certain magnitude. A logical approach to t question is to maintain a flexible valuation process to storm water control and to apply relatively inexpensive remedies that ca~ be applied to existing developments, things that give home owners some incentive not to use more fertilizer than ~eeded. Sedimentation ponds have Y is June 16, 1977 (Adjourned from June 15, 1977) becomes a more effective control measure since the pollutants that come from a highly impervious s~te tend to be associated more with suspended loads rather than being soluble. In lower density urban development (single-family) not as much of the pollutant loading is' associated with the suspended load since it is soluble, sedimentation alone does not tend to be an effective control measure in terms of phosphorus control. Dr. Iachetta asked the trade-offs on this sort of comparison other than phosphorus. Dr. Grizzard said it works the same way with nitrogen but appears to work opposite with heavy metals. In lower density applications most of the toxic metals, primarily lead and zinc, are associated with the suspended load, but tend to be more soluble in higher density development That is the problem that in the tong-termis important to the health of the reservoir because high concentrations of lead and zinc have been seen arising from urban storm drainage. Heavy metals eventually accumulate in the reservoir and tend to disrupt its healthy state. Mr. Henley asked the type of processing and how expensive it would be to remove the pollutants. Dr. Grizzard said removal is enhanced by the same type of chemical treatment that would be used for phosphorus removal. Promoting drainage into the soil has been shown to be effective in heavy metal removal. Mrs. David said what Dr. Grizzard had mentioned so far indicates the desirability of continuing monitoring because the problem will change and will need to be identified. Mr. Fisher said he has a problem with monitoring for its own saka. The Board's concern is the implementation of measures that will have a positive effect on the reservoir over a number of years. Monitoring will only tell how well the regulations are working. Dr. Grizzard said that was right. Monitoring should be tied to a control program with assessment of the affectiveness of that program being carriad on at the same time. Mr. Fisher said most of the conversation so far has related to the Betz report. He asked Dr. Grizzard's reaction to the ordinance and performance standards drafted by the staff. Dr. Grizzard said with the information developed by the staff, and using the Betz ~report, it should be possible to establish phosphorus export rates that would adhere to generally undeveloped conditions. The export rates established would be dependent on factors generated from data collection for one year. The estimates could be enhanced by looking at similar types of work, in fact, Betz made reference in their report to using data from the Occoquan program. Dr. Grizzard Said he feels the information exists on which to have export rates for control of sediment and phosphorus. Mr. Fisher said this would leave the work of developing a structure, or ~echnique, or combination of these, to the ingenuity of whoever is doing the work. Dr. Grizzard said he felt that is the best approach. If the Board goes to the most effective method of removing pollutants from storm drainage, it may be more effective than is necessary and more expensive than anything else that can be undertaken. Mr. Fisher asked if Dr. Grizzard was suggesting that in some cases a grassy stretch can accomplish a significant reduction in runoff pollutants and that this is an alternative that could be used in low density residential neighborhoods as a d. rainage cmnv~yer rather than curb and gutter. It would have more effectiveness where the velocity of runoff is lower. Dr Iachetta said this suggests that curb and gutter should be minimized. Dr. Grizzard said yes in certain cases. Dr. Iachetta asked the cutoff point between low and high density. Dr. Grizzard said medium density might be a better definition; lot sizes from four-tenths of an acre to six-tenths of an acre. Mr. Dorrier asked if any thought had been given to developing two diffe'rent sets of standards depending on the closeness of the development to the reservoir. Dr. GrizzarH said it is known that pollutants generated in a subdivision near the ridge line as-far back in a watershed as you can get will decrease significantly before they get to the impoundment. There will be removal in the natural stream bed. He is not in a position at this time to dra~ a line to see where that point of decreasing effect would lie. Mrs. David said it seems as though it becomes a matter of how close development is to the water. Dr. Grizzard said if you have storm drainage flowing over land before it gets into the perennial stream, then a buffer zone has a beneficial effect, but the actual distance in stream m~les from the headwaters of the impoundment effects a reduction also. Mr. Fisher said in the ordinance which Mr. Bailey had helped write, Mr. Bailey questions whether or not anything should be done for new development. He says that if all the property that is proposed for development over the next twenty years is developed, the increase above existing non-point sour.ces will be 6.6 percent. That is true only if it is assumed that no improvements will be m~de to existing non-point sources, but the Betz report specifically says non-point sources must be reduced by a significant amount in order to accomplish any reversal of conditions in the reservoir. Dr. Grizzard said the phosphorus loading on the reservoir is at such a level now that there is essenvially no hope of achieving a reversal unless a significant reduction in existing non-point sources is realized Zf the non-point source pollution problem is approached, it has to be a comprehensive approach, including elements of education for the agricultural community, elements that address the existing non-point problem, and a look at ~uture development. Dr. Zachetta asked if there is any way to construct a set of standards applicable within some distance of the impoundment so there would be more ground for the water to run over before it enters the reservoir. Dr. Grizzard said establishing a buffer would be a positive step as long as the buffer has its integrity retained and a point discharge is not produced by collecting storm drainage upstream. With an analysis of soil types and soil adjacent to a body of water, a reasonable distance can be recommended. Mr. Dorrier asked if there is any way to formulate controls to reduce phosphorus by six percent without having these controls apply to the whole watershed. He is concerned the Boa~ may come up with something too restrictive for the results they will accomplish. Dr. Grizzard said a high level of pollutant removal can be obtained on some sites and not others; technically this can be arranged. Mr. Dorrier said he does not feel there is enough knowledg to know where the cutoffs are. Dr. Grizzard said there is~sufficient knowledge to be able to estimate the loading permissible within the context of maintaining good water quality. The problem then becomes one of distributing those loads upstream in some equitable manner. The trick is to come up with the most cost-effective distribution of management alternatives. Mr. Dorrier asked if upstream means within a certain distance of all tributaries. Dr. Grizzard said he means upstream of the impounded body of water and not just any upstream area. A lot of the alternatives are not well defined and are the ones which are not so June 16, 1977 (Adjourned from June 152 1977) Mr. Fisher said the Betz report indicates that something should be done. At this point, the Board does not have anyone with the technical expertise, or time, to spend develo ing the standards for an ordinance. Mr. Fisher asked Dr. Grizzard if he had considered undertaking this task for the County. Dro Grizzard said he would be interested in working on the problem. There are studies and data which could be used in developing a comprehensiw management plan. Dr. Grizzard said he did not think that setting methods of achieving poltutan~ reduction in an ordinance is the way to accomplish this. He thinks there is a whole gambit of approaches to take. At the same time, an effort is needed to encourage the use of some of the more innovative and less costly aplpr~.aoHe-~ to storm pollution control. These should be integrated into a management plan. Dr. Grizzard said he feels confident to work in this area but his consideration of undertaking the job would be the amount of time required. Dr. Iachetta asked how long this work would take. Dr. Grizzard said he would like to have time to read through the appendices of tha Betz study before giving an estimate. However, the Board should understand that the bottom line may be a need to have more on-site evaluations. He was not sure he could come up with a developed management plan in a short period of time. Mr. Fisher said the Board has no time left in which to consider more field analysis. The question now is one of developing a monitoring program to go into operation with an ordinance and the comprehensive management plan. The Board needs to resolve this question and cannot do it until they see a standard that is technically adequate. Mr. Agnor said when he had discussed this work with Dr. Grizzard, they were talking about technical help on drafting an ordinance; now the watershed management .plan is included Dr. Grizzard said the time needed would depend on whether he would be providing assistance to the County Staff or bringing in a fininshed ~roduct. Mr. Dorrier said the Board had discussed earlier this afternoon setting up a committee between the County, City and Rivanna Water and Sewer Authority. He fe. lt that if such a committee were set up it would be possible for Dr. Grizzard to wo~rk with that committee an~ the Betz report and with these three groups working together report bac~k to the Board at the end of August. Mr. Fisher asked Mr. Agnor's recommendation. Mr. Agnor said the staff is "plowing new ground" in this ordinance. In the interest of time, the lass work the staff is expected to-do, and the more work the consultant can do, the faster the ordinance will be completed. Dr. Grizzard said by the end of next week he could give an estimate of the time frame. Mr. Agnor suggested that Dr. Grizzard give two proposals to the Board, 1) time and cost for he and his colleague being the principals with the staff assisting; and 2) the time and cost for a reversed rola. Dr. Iachetta asked Mr. George Williams, Executive Director of the Rivanna Water and Sewer Authority, if his staff would work with Dr. Grizzard. Mr. Williams said yes. Mr. Dorrier said he felt the City would like to have a formal committee appointed consisting of people from the Board of Supervisors, City Council and the Rivanna Water and Sewer Authority to work on the situation. Mrs. David said at this time, the Board needs a task force at the working level to come up with what can be done, then a committee should be appointed on the policy-making level. Mr. Dorrier said he felt these people should be working simultaneously. Mr. Agnor said there is an existing technical committee for the Rivanna Water and Sewer Authority's operation which is comprised of, the Executive Director, the Director of Operations, the County Engineer and Director of Public Works for the City. They are a functioning technical committee. Added to that committee to work with Dr. Grizzard would have to be a person from the legal staff. Mr. Dcrrier said there are no et~cted officials on that committee. He felt if this problem could be ironed out with elected officials it would make the ordinance more pswerful. Mr. Fisher said he would prefer to wait before appointing such a committee and said he felt the Board had done what they came to discuss tonight. At 9:10 P.M., motion was offered by Dr. Iachetta, seconded by Mr. Dorrier, to adjourn tl meeting until June 29, 1977, at 7:30 P.M. in the Albemarle County Courthouse. The motion carried by the following recorded vote: AYES: Mrs. David and Messrs. Dorrier, Fisher, Henley and Iachetta. NAYS: None. ABSENT: Mr. Roudabush. S
