__________
The meeting was called to order at 7:10 p.m. by Mr. Richard Collins, chosen as chair for this
informational meeting.
The meeting began with Mr. Collins introducing Mayor Blake Caravati, Chairman Sally Thomas and
Chairman Randy Parker. He asked these persons to speak.
Ms. Thomas read from a prepared statement. I will bring you up-to-date on the Albemarle Board
A
of Supervisors actions or study sessions. We had a work session on water supplies on September 5, 2001.
=
For background materials, we had papers from citizens and the League of Women Voters regarding some
recurrent issues in water management. We also had a memo from the Countys Engineering Department
=
staff regarding something called integrated resource planning. It may go by different names in different
A@
organizations, but it was described as being a way to integrate water supply needs with other community
values such as environmental resources, economics and land use planning. Our staff suggested that the
current water supply project, which is what brings us together tonight for this important input session, meets
some, but not all of the principles in a system of total resource management. The resource we are talking
about is the life blood of our community. We can all agree that water is important, but disagreements can
start quickly after that initial agreement. Focusing a spotlight on total water resource management provides
an opportunity to deal with longstanding issues and to think pro-actively to prepare for future challenges,
and to think about the sustainability goal of acting today in ways that do not destroy our resources for the
future.
On the other hand, we are close to, if not already in, a situation where the water supply is
vulnerable to severe drought. We need to make some decisions fairly quickly in order to be responsible to
water users. We can also commit to begin tonight a process which goes beyond simply providing additional
water supply capacity. The we in any of these statements is a simple pronoun, but it includes complex
A@
relationships and responsibilities shared by citizens, by advocates for particular bodies of water, by water
users and by the authorities which in turn include the City, the County, the ACSA and most crucially, the
RWSA. It should also include at some stages the communities which are impacted downstream by our
uses of our water.
I think the Albemarle Board feels the RWSA and their consultants, VHB (Vanasse Hangen Brustlin,
Inc.), have creatively put together a package of recommendations to address the communitys water
=
quantity needs and that package has a high probability of being permitted by Federal and State agencies.
Their proposal is complex and each piece of it should be analyzed carefully, but await some decision by us
before each can proceed to get the more stringent analysis it needs. Its a chicken and egg situation,
needing the go-ahead in order to get more information which is needed for a definite decision to go. But,
while we are involved in that discussion, we somehow, somewhere, need to do more. There are really
difficult issues involving adequate stream flow, how to define that, and how to achieve it.
The other major issue involves managing the sedimentation of our relatively small reservoir which
sits in a relatively large watershed full of very erodible soils. We need to link water supply decisions to the
Countys planning for its development areas. We need to work on the demandside of the supply demand
=
equation. We need to consider the environmental and cultural importance of our running rivers. We need
to link surface water and groundwater issues. We need to establish a sense of responsibility for fitting all
these various aspects into one comprehensive management of our water.
The Albemarle Board asked our staff to look deeper into establishing an integrated resource
planning process. The various policy boards have received that staff initial memo on that subject. I hope
that while proceeding expeditiously with the water supply project that is the focus of tonights meeting, we
=
officials can also commit to looking at our water resources in the broadest possible light.
@
Mr. Caravati said City Council has not taken an in-depth look at the water supply for the future.
However, City Council knows this is an important issue. It is particularly important because it is a regional
issue. Council appreciates that it is both downstream and upstream, and we are not protecting just our
September 27, 2001 (Adjourned Meeting)
(Page 2)
resource, but protecting a more super regional resource that all must have. To that end, there has been no
clear definition of how to proceed on the part of Council. Most members have participated in various
meetings throughout this process with the consultants. An integrated look is a necessity because it is what
will allow us to live, and to accommodate the future. There is a keen sense about a small reservoir in a
very large watershed. A couple of the issues surrounding the reservoir, particularly siltation, are most
important. As far as the ultimate end of the capital improvements that will go on, he should mention that
the University of Virginia plays a big part in this. They certainly should be, and will be, at the table. They are
the Citys number one customer and probably the largest customer in the region. The City will proceed with
=
the County and the University, the ACSA and the RWSA, is together. It is an important venture not only to
our pocketbooks, but more importantly, to the environment.
Mr. Parker said the RWSA is a wholesaler and it has two customers, the City, and the County
through the Albemarle County Service Authority, of which he is Chairman of that Board. When RWSA and
the ACSA were set up through the Four-Party Agreement years ago, a voice in these decisions was given to
Albemarle County through the Service Authority, and the Board of Supervisors. That is the reason he is
here. He will be listening to input and taking his lead from the Supervisors.
Mr. Collins then introduced Mr. Gene Potter, member of the Rivanna Water & Sewer Authority staff.
Mr. Potter is to give a report on what the consultants think should be done to meet reasonably foreseeable
water needs.
Mr. Potter introduced Ms. Carolyn Buskar, Ms. Cheryl Snelly and Mr. Stephen Bowler, members of
staff who helped put together the presentation (slides). He said that five years ago VHB was hired by
RWSA to begin a water planning process. The goal of that process was to put into play supplemental raw
water supplies that would meet the needs of the Charlottesville/Albemarle urban water service area. The
intended goal at that time was to obtain both Federal and State permit approval to construct and put into
service the Buck Mountain Reservoir. That goal, which had been the RWSAs long-range plan since 1977
=
was redefined on the advice of the consulting team who said a Federal permit would only be issued for the
most practicable, lease environmentally-impacting alternative or set of alternatives. That then became the
redefined goal to meet future water needs. With that in mind, the process that was started in 1977 started
over again, essentially from scratch. To date, four reports have been generated. The report summaries
were made available for those present tonight, with the exception of the fourth, Recommended Alternatives.
Mr. Potter said he would review the significant conclusions from these reports. He showed a slide
depicting the supply analysis. He said the figures represent the 1997 and year 2050 safe yields of existing
water sources in the urban water supply system. The numbers are based on the 1930's drought stream
flow records. That was the worst drought of record. The amount of water available is defined in terms of
safe yield which is the amount of water which can be withdrawn from a reservoir over the duration of the
drought. It is determined by what is received in terms of stream flow and precipitation, and what goes out,
primarily, evapo-transpiration, seepage, downstream releases, and takeouts for water demand, and the
volume of the reservoir. A significant part of the future need for supplemental water supplies is based on
the fact that the volume of the South Fork Rivanna Reservoir (SFRR) is being reduced due to
sedimentation.
The next slide summarized the demand analysis. Two different approaches were used to come up
with the report demand figures. The first approach was to look at the historic demand from 1973 until 1996,
determine the line of best fit for that data and extend that to the year 2050. That statistical approach yielded
a future 2050 demand of 20.4 mgpd. The demand was broken down into its individual components. Total
demand being the sum of the individual components of demand. One of these techniques was based on
population trends and per capita water consumption, the second was based on build-out under the
comprehensive plans for each of the jurisdictions, and the third was based on historic trends in each of the
components of demand.
Mr. Potter said this study concludes, using all four approaches and the best available data, that
demand can be expected to continue to rise from its current level to the design year 2050. The two reports,
supply analysis, and demand analysis, have been presented to the public, revisions made, and
subsequently both were presented to Federal and State regulatory agencies for review and both have been
accepted.
Mr. Potter said the Analysis of Alternatives identified and evaluated 33 alternatives to meet future
A@
water supply needs. Those alternatives were listed in one of the hand-outs tonight. Finally, the
Recommended Alternatives report, which is to be discussed tonight, ranks the viable alternatives for
A@
implementation. With one exception, he will mention only the alternatives recommended for immediate
implementation. The reason they are recommended for immediate implementation is the concern that if
there were a 1930's drought-type situation, there would not be enough water in the current system to meet
projected demands. He said the report discusses further the other alternatives and it is available on the
Rivannas Web page, or a copy can be obtained at the RWSAs administrative offices.
==
Mr. Potter said the first alternative is a release scenario at the SFRR. With the exception of a 30-
day period in 1999, the RWSA has consistently released a minimum of 8.0 mgpd downstream of the SFRR
dam. This alternative recommends that in the event of a drought RWSA reduce the release to mimic the
nature in-flow until other alternatives have been placed into service. A statistical examination of available
hydraulic stream flow records indicate that flow would be less than 8.0 mgpd one percent of the time.
Mr. Potter said the second two alternatives recommended for immediate implementation are water
September 27, 2001 (Adjourned Meeting)
(Page 3)
conservation and drought management which would help to eliminate future needs, as well as manage the
currently available resources in the event of a drought.
Mr. Potter said the fourth alternative for immediate implementation is to reduce the sediment load
in the SFRR. That will be a long-term undertaking and will not result in immediate improvement. Earlier he
said that reduction in volume is responsible for significant portions of the future need, approximately 50
percent of it. The cause of that reduction is the on-going sedimentation of the SFRR. To whatever extent
sedimentation can be reduced, the useful volume of the reservoir will be extended.
Mr. Potter said the last alternative is for crest controls. The idea is to increase the existing volume
of the SFRR by adding four-foot crest controls to the top of the dam. There are several ways to do this.
One way is to add a five-foot rubber bladder to the crest of the reservoir, such as the one added to the
Sugar Hollow Dam to replace the gated control structure there which was an impediment to the passage of
the big storm in June, 1995. He said there are several technologies available to do this. At the time of the
rehabilitation of the Sugar Hollow Dam, the consultants evaluated four different technologies and the
rubber dam was the recommended alternative.
Mr. Potter said the one exception to the alternatives listed above is dredging. He said the next
speaker, Mr. Bob Pound, will go into that in detail. Before that, he wants people to know the sheer volume
involved in any dredging alternative. When the SFRR was constructed in 1966, it had a recorded volume of
1.76 million gallons. Its current volume, based on a March, 2001 bathymetric survey, is 1.15 million
gallons. This calculates to a total loss over 35 years of just over 3.0 million cubic yards, or 236 cubic yards
per day. He will not talk about how to dredge out that material, or how to de-water it, or even how to
dispose of it. He will not talk about environmental impacts such as noise, odors, traffic or odor problems in
treated water, other than to say that based on his experience, the solids removed as part of the water
treatment process smell worse than almost anything ever smelled at the wastewater treatment plant.
Mr. Potter said that in earlier presentations he spoke of 236 cubic yards per day as being equivalent
to 12, twenty cubic yard dump truck loads every day, 365 days a year just to maintain the status quo. His
statement was wrong. A twenty cubic yard of dirt cannot legally be hauled over the highway because of
weight limitations. Even though the truck volume might be twenty cubic yards, it actually would be hauling
between ten and 12 actual yards of dirt. His revised figure, because of the weight limitations, is 20 to 24
trucks per day, 365 days per year, for however long it takes to maintain reservoir capacity until
sedimentation load is reduced. That can be one truck load per hour 24 hours per day, or it can be one
truck every 20 minutes, eight hours a day. It is a lot of truck loads.
Mr. Potter said in addition to that, to restore the SFRR to its original capacity and its design 12.0
mgpd safe yield, in addition to those dump trucks running every day, something needs to be done to the 35
years of accumulated sedimentation, about 3.0 million cubic yards of material. That is equivalent to almost
19 feet of material stored on 100 acres of land. He is not suggesting that dredging is not doable. It makes
sense to extend the useful life of the reservoir. One must be realistic in grasping the enormity of what
dredging means. If it is cost-effective, or even if it is not cost-effective and the urban water users are willing
to pay for it, dredging will be done. He then introduced Mr. Robert Pound, Vice-President of Aquadredge, a
specialized hydraulic dredging firm. He said Mr. Pound went out with Mr. Thomas Dunn, RWSAs
=
engineering representative from OBrien & Gere Engineers, Inc. They looked at some potential dredge
=
spoil sites.
Mr. Pound said he would speak about the different ramifications and different methodologies which
can be used to dredge a body of water. He said he has been vice-president of Aquadredge since 1975.
They do projects for the Federal government, state, local and private organizations. They have done
Superfund toxic waste sites, marinas, fresh water and salt water bodies of water. He was asked to talk
about the nature of hydraulic dredging which is one of the alternatives proposed as a way to mediate the
SFRR. He said there are three basic parts to dredging when using the hydraulic method. There is the
dredging process itself. There is the mobilization of the plant onto the site. There is the construction and
maintenance of the containment areas that the dredge spoils are placed into. He said dredging sounds
simple at first. Take the material, dig it from Point A, pump it to Point B. However, each job is unusual and
unique. He has looked at the reservoir site, observed the nature of the body of water, the sediments in it,
the debris in the body of water, some of the possible sites looked at as containment sites, and the distances
these sites are from the dredging area. Also, there have been many discussions about how long a period
of time this dredging project would take.
Mr. Pound said the size of the dredge plant itself will be a factor on how fast the project can be
done and its overall cost. Also, the final grades to be obtained to be sure the dredge plant can float in the
designed depths must be determined. They have to look at the amount of materials to be taken out per
dredge event. If a large amount is to be taken out, a larger plant might make more sense because the
higher costs of mobilizing on the site would be offset by the higher production rates. If the amount to be
taken out over a period of time is a smaller amount, smaller machinery is more cost-effective because it is
less expensive to bring it to the site and mobilize. Particularly, if this is to occur over several years only
several months each time.
Mr. Pound said they look at the type of materials in the waterway, grain size, mud, sand, clay,
organic matter, debris, rock, logs, sticks and other organic matter, human debris, etc. These are things
which slow down the dredging process. A certain velocity must be maintained by the water in order to
pump the dredging material through the pipeline to the spoil area. The larger and heavier the material, the
more velocity is required to carry the material through. They look at the distance the dredge material must
be pumped, and the size of materials will decide if boosters are needed to pump the required distance.
September 27, 2001 (Adjourned Meeting)
(Page 4)
Boosters increase the cost of the dredging operation.
Mr. Pound said that in the SFRR there are a lot of different materials, such as sand, mud and
coarse gravel. He feels there are other objects and materials which have not been identified at this time
because significant investigations have not yet been performed. The mobilization he mentioned previously
is simply the cost to bring the plant on the site and the number of events done. The size of the equipment
will affect that cost.
Mr. Pound said the third cost to be looked at is the size of the spoil area, both to construct it and
maintain it. If the area is large enough to do one event and leave the material on site, that will be the
cheapest way. More events are required for the smaller the containment area. Each event requires a down
time to allow the material to dry and settle out. Then, the material would have to be trucked away and the
area reclaimed for the next event. The type of material, how long it takes to dry, how much can be put in a
truck, and the distance to be traveled, all affect cost. There are many parameters which need to be
investigated and presented for alternatives if the dredging method is chosen.
Mr. Potter asked Mr. Pound about the consulting engineers estimate of costs for this project based
=
on his experience. Mr. Pound said based on projects they have done over the past few years, the cost
range is not out of line. He cannot give an exact cost because of all the parameters which have to be
considered. In the last five years, they have not bid a job where the dredging itself was less than $6.00 per
yard for this type of project. In addition, there is the cost of procuring land and the design and construction
of the spoiler. He believes this job would require a booster pump because of the grain analysis and the
distance to the pump.
Mr. Collins said a number of citizens have previously indicated they felt the projected costs for
dredging were too high and the benefits underestimated. Therefore, a person was invited to speak tonight
about that aspect. It has been seen this evening that the original estimates of costs and the associated
issues are in line. He then invited members of the public to speak.
First to speak was Mr. Nick Evans who said he lives in Barboursville. He is Chairman of the
Thomas Jefferson Soil & Water Conservation District (SWCD). He said the water supply project has led to
a sensible mix of near-term solutions. There are modest engineered alternatives which build on existing
infrastructure, and measures such as drought management and water conservation that will require
individuals to take responsibility for living within the natural resources base. He does not think this is the
time to end the discussion. How to interface with water supply planning, water resources protection and
planning for growth and development needs to be reexamined. Water supply planning and planning for
growth are linked. It is the resource protection planning that often gets disconnected from the other
planning processes. Sustainable water supplies need to be in place to meet the needs of homes and
businesses enabled through land use decisions. The cumulative affect of incremental actions should not
degrade the natural resource base.
Mr. Evans said there is a lot of talk these days about integrated resource planning. This concept
reflects an approach to community decision-making where sustainability of the natural resource base gets
equal footing with other interests. In terms of what is practical and immediate, integrated resource planning
might mean firming up the connections between existing entities operating in the realm of water resource
protection, and entities which manage the water supply and make near-term and long-term planning
decisions.
Mr. Evans said the SWCD one existing entity which operates in the realm of water resources
protection. It serves a multi-jurisdictional area which enables it to work with individual localities toward
uniformity of approach across the watershed. He outlined three areas where he feels the District might
partner with RWSA, the City and the County, in the future. 1) Sedimentation: reducing sediment influx into
the reservoir will continue to be part of the water supply management plan. The District and the County
have been working together on sediment reduction for decades, but it continues to settle and accumulate in
the reservoir, so it is hard to tell how effective the methods used have been. More needs to be known about
how the sediment transport system works in order to determine the most cost-effective way to apply
resources.
Mr. Evans said the Thomas Jefferson SWCD Water Resources Advisory Committee looked into
this issue during the past year and developed a draft proposal. The proposal includes data gathering and
monitoring to help better define where the sediment comes from, and testing of alternative mitigation
strategies to find the best approach to working with the problem. This activity is in the realm of soil and
water conservation, and the District is prepared to serve as project umbrella, but resources will be needed
to accomplish this. He would like for the SWCD, the County and the RWSA to get together with a proposal
and seek funding for it. 2) Water Budget: developing a regional water budget means integrating data on
surface water and ground water with meteorological data to give a real time picture of how much water
resides in the various components of the watershed. This tool can be extremely helpful in making water
supply management and planning decisions, particularly, once data has been accumulated over a period of
years, and long-term trends can be established. For example, it is difficult to make an equitable policy on
how much water to release from a given reservoir if there are not good numbers on how much water is
flowing in from the top, how much is being contributed by groundwater and how much is being lost to the
atmosphere through evaporation.
Mr. Evans said it is difficult to monitor the effect of development in different parts of the County on
groundwater supplies if there are no long-term numbers on water table levels. In order to begin developing
a regional water budget, additional surface water gauging stations and groundwater observation wells will
September 27, 2001 (Adjourned Meeting)
(Page 5)
need to be established. Somebody will need to tie it together with meteorological data on a computer. This
is a project which could involve multiple players with long-term monitoring and data base management
tasks. The SWCD stands ready to help put the pieces together. 3) Conservation Easements: (Mr. Collins
interrupted to ask Mr. Evans to complete his presentation.) Easements are a powerful tool. A foundation is
being developed to administer the SWCD program, and they aim for lands which are critical for water
interests.
Mr. Angus Murdoch said he was present with a statement from the Rivanna Conservation Society.
RCS supports the RWSA proposal for a four-foot crest increase at the SFRR as the best, short-term
alternative to increased municipal water supplies. However, before the Authority proceeds with the
permitting process, several important environmental issues related to regional water resources need to be
addressed. 1) Moormans River. The highest priority should be given to restoring a greater proportion of the
natural flow of the Moormans River, especially during low flow periods. The excessive diversion of water
from the Sugar Hollow Dam to municipal use continues to compromise the ecology of the Moormans. The
scenic river status of the Moormans River is one of Albemarle Countys important environmental assets and
=
must be protected by restoring vigorous natural flows in the river. 2) Water Conservation and Drought
Management. They appreciate the current water conservation efforts of the City and County. However,
additional efforts need to be taken. The RWSA should adopt more sophisticated early warning systems for
droughts and implement strong voluntary and/or mandatory water conservation measures well before
reservoirs reach critically low levels. Drought management plans should budget water for run-of-the-river
releases to maintain healthy riparian eco-systems even during low flow conditions. 3) Dredging in the South
Fork. Over the long-term, the SFRR will require periodic dredging to prevent the creation of a serious
environmental and public safety hazard. All parties should recognize that the proposed crest increase is at
best a temporary stop-gap measure. Analysis of various dredging options for the SFRR need to be given a
higher priority. The future costs of dredging should be treated as the costs of maintaining the reservoir and
included in the present water rate structure. 4) Minimum Releases from the SFRR. RCS advocates a
formal, guaranteed minimum release of 8.0 million gallons per day from the SFRR. If RWSA opts for a
variable flow release, this variable release should be equal to the actual in-flow in the South Fork, plus any
diversions from Sugar Hollow to the Ragged Mountain Reservoir. Any efforts to link SFRR releases to the
run of the river will require major improvements and flow monitoring infrastructure, including the
construction and rehabilitation of numerous gauging stations throughout the watershed. 5) Future Water
Supplies. During the 1999 summer drought, water levels in the Rivanna River were dangerously low.
Droughts of similar size have occurred in each decade since the 1930s. Several factors are presently
increasing water demands from the Rivanna River watershed. These include residential, commercial and
industrial demands within the RWSA and the Fluvanna County Aquasource service areas, increasing
groundwater uses in both counties outside these service areas, and increases in impervious surfaces such
as new construction and paved parking lots. Accumulative impacts of increased uses in both surface and
groundwater throughout the Rivanna watershed are significant and need to be carefully monitored. There
are already some indications that groundwater levels are declining in some areas of the County. The
negative impact of excessive groundwater withdrawals on surface water availabilities is well established.
RCS supported the Countys decision to drill observation wells for monitoring groundwater levels. While
=
RWSA exists to produce and distribute potable water, no County agency is presently designed to monitor
ecological conditions of local rivers and streams. RCS advocates the creation of a new multi-jurisdictional
agency focused on these environmental watershed issues.
Mr. John Via said he has had many years to think about what he would say tonight. He will say we
A
told you so. When land was taken at Buck Mountain, everything was supposed to have been solved. We
@
tried to get you all to pick from another watershed area, and you wouldnt do it because you are using the
=
same water from the same impoundment area as now. If you could go elsewhere and use the money put
into the Buck Mountain area, it would be beneficial.
Mr. John Kauffman said he lives in Free Union, and is with the Department of Game and Inland
Fisheries. They support construction of the bladder on the SFRR feeling it is a logical use of the existing
reservoir, and the most inexpensive way to increase the yield in the facility. There are two opportunities in
implementation of the overall project. One would be a more aggressive program for riparian protection to
reduce both sediment and nutrients into the reservoir. Second would be an aggressive demand reduction
program that would put into place aspects such as better seasonal pricing and an educational program to
reduce continuing demand. They also think the public recognizes the value of the river system and work
needs to be done on reestablishing natural flows into the States Scenic Moormans River. He said the
=
proposal for an integrated plan encompassing the whole system would ensure there would be water again
in the Moormans River.
Ms. Lois Rochester was present for the League of Women Voters. She said this is a critical stage
in the communitys determination of how to proceed to provide adequate public water, as well as
=
addressing important water-related issues. Will a patchwork approach be continued, or will a new
paradigm be reached for in managing water resources? Over the course of this water project, the League
has worked to inform itself, other citizens, and elected officials, about water issues important to the whole
community. The Leagues publications, presentations and public statements have looked at water supply
=
planning in the broader context of comprehensive management of water resources. In previous
communications, the League has suggested development of a mechanism for accomplishing
comprehensive water management, possibly in the form of a commission or council. In September, the
Albemarle County Water Resources staff presented their own professional assessment of the communitys
=
water management. They also looked at problems inherent in the current way of dealing with multiple
water issues. To address such problems, staff recommended to the Board of Supervisors an integrated
resource planning approach which has been mentioned many times this evening. Several possibilities were
put forth as to the form such an approach might take.
September 27, 2001 (Adjourned Meeting)
(Page 6)
Ms. Rochester said in keeping with the Leagues longstanding support for comprehensive water
=
management, it wholeheartedly supports the IRP concept, even though the form is not yet set. They urge
the City and the County to work together to set this concept in motion at the same time as, and in concert
with, the on-going planning for public water supply. Help exists for this process, The Virginia Soil and
Water Conservation Division of the Department of Conservation and Recreation provides a model for an
administrative entity to carry out integrated resource planning. In accordance with the Water Quality
Improvement Act, the DCR has created watershed round tables for the nine major watershed regions of
Virginia. Charlottesville/Albemarle sits in the Piedmont Middle James part of the larger James River
watershed. The round table concept seeks to accomplish goals through strategies similar to those of
integrated resource planning. Thus, the DCR and the local SWCD office could provide infrastructure,
expertise and support. In addition to facilitating the development of a local IRP, they could help synchronize
planning efforts with statewide water protection goals.
Ms. Rochester said with regard to the water supply project recommendations themselves, the
League strongly endorses the proposed incremental approach to meeting public water supply needs. This
strategy of matching source management and development to changes in demand in a gradual, interactive
way, will enable efficient, responsible use of water resources. It will also allow for other water needs such
as recreational uses, minimum in-stream flows, and will serve to protect water resources for future
generations. As has been done in the past, the League also supports the recommended drought
management and water conservation alternatives. The League recognizes that they are not, strictly
speaking, alternatives, but rather, a required component of the community plan. Measures to conserve
water and to respond to serious drought are already in place, but the League suggests that they be refined
and expanded, ideally, by means of an integrated planning mechanism. A community-wide commitment to
the implementation of these recommendations could result in important additional benefits, such as
economic savings, improvement of water quality, and maintenance of aquatic eco-systems. Alternatives
that involve improvements to already existing water resources, such as sediment load reduction and SFRR
crest controls, should be pursued. Integrated resource planning would benefit essential efforts underway to
reduce and prevent sedimentation and it would be an important mechanism to address impacts of crest
controls. The League has also suggested a further study of dredging in spite of all its problems, in order to
expand the life of the major reservoir. An IRP could help in the assessment of the need for and potential
impacts of dredging. These recommendations all assume a sufficient public water supply can be assured
by using what we have and using it more efficiently, instead of, by the more costly and likely non-permittable
construction of a new reservoir.
Ms. Rochester said on the whole, the League reviews the recommended alternatives as consistent
with environmental protection and sustainability goals of the community, and of the regulatory agencies
which have guided the project. In a real sense, the water supply planning process represents an
environmental assessment and negotiation between the community and the eco-system it inhabits. This is
an excellent mode to guide the community in present and future decision-making about its water needs and
supplies. Achieving sustainability goals embodying the recommendations presented requires a new
community-wide resolve to protect the watershed. During the course of the water supply planning process,
a new century has begun. It affords an opportunity to take a fresh look at how critical resources are
managed, and to move into that new paradigm. This must be done with increased scientific understanding
of those resources, and with the informed and full participation of citizens and their elected officials.
Mr. Collins said the RWSA Board has benefited immensely from the Leagues work and to have it
=
summarized this evening so succinctly is a compliment to this organization.
Mr. John Schwab said he had served on the Rivanna Roundtable, and he lives on property next to
the SFRR. He said droughts have been mentioned this evening, but he is more concerned about an event
such as (Hurricane) Camille or (Hurricane) Agnes and how a bladder would hold up during such periods.
Also, looking at the current safe yield of 7.2 million gallons, he thinks a second reservoir or second place for
water needs to be reconsidered. If there were another event like Agnes or Camille, and the dam went
A
down what would be used for water? He thinks that should be answered tonight.
@
Mr. Bruce Dotson said he is a resident of Albemarle County. He is concerned about the land use
consequences of water supply. Each year there are about 200 building permits issued for the rural area of
Albemarle County and thats too many. He is concerned that if the problem is not addressed, and there is
=
not an adequate urban water supply, development may be forced for lack of water further into the rural
area. While land use efforts are going forward to try and reduce that impact, the water supply needs to
work in a consistent way to support more in-fill development in the urban community. This is an urban
problem, but it is also a regional problem, and the urban and rural needs have to be balanced at the same
time.
Mr. Blair Hawkins said he lives in the City, and is the editor of a new community resource
newspaper called The Witness Report. He distributed copies of his paper to people in the audience. He
A@
said the worse time to have a drought is in the middle of a flood. That is when there is a shortage of
drinking water. Most dam failures occur during a flood.
Mr. John Hermsmeier said he lives in the County. He said the issues with the water supply study
are not so much about the study itself, but the fact that it is conducted separately from, or is only a piece of
a truly comprehensive water plan. It is based on local comprehensive plans which were made without full
consideration of their impact on water usage, and therefore, supply. The plans on which it is based can be
September 27, 2001 (Adjourned Meeting)
(Page 7)
changed if citizens decide to change them, yet the study confines a discussion of growth management to
the parameters of existing policy. He asked if the community has decided to use 20.0 million gallons of
water in the year 2050. He does not think it has gone through a process to make that decision. Integrated
resource planning could overcome this problem if it were pursued without delay. Otherwise, water supply
decisions will be made and then the roles and policies of a community water plan established. Stop-gap
measures may be acceptable if they buy enough time to create such a plan, and if they address the short-
term yield question. He suggested that water be treated like land in terms of planning. Watersheds are
primarily land. The term land use planning is used, so why not talk about land supply planning. It is a
A@A@
finite resource whether talking about a county boundary or a watershed boundary. When talking about
water, it is called water supply planning. The water supply is simply the amount of precipitation that falls
A@
over a defined area. How much is stored in reservoirs, or gathered underground for use is the question.
He suggested that all think about water use planning and not water supply planning. While there is land
A@A@
for millions of people, and water could possibly be provided for millions of people, development and
associated population will likely stabilize at far less than that because we have chosen directives like DISC
and the protection of open areas instead of turning the entire community into one big growth area. Land
use planning implies the protection of certain uses, so places a limit on other uses. It also implies a
stopping point in the increase in population and associated development. Water use planning needs to do
the same, not necessarily in terms of carrying capacity, but in terms of the choices of the free people. If we
dont want to pave over the landscape, is it possible to stop it? Water policy should not be a covert growth
=
policy. As population grows, it becomes harder to provide a quality of water and a quantity of water. The
per capita access to free flowing, non-dammed rivers drops with population growth and drops even more if
this growth is associated with more dams. Growth is a double whammy. There are more users, and more
watersheds are sealed with the development associated with this growth. There is less infiltration, less
available groundwater and more pollution from the impervious surfaces. To sum up, the community can
decide its water use and its associated implications.
Mr. Dennis Rooker said he is a citizen of Albemarle County. He has three questions to ask the
panel. First, what process will be followed in making the ultimate selection among the options? Second,
what are the mechanisms in place to fund the cost of these options? Has any discussion been given to the
implementation of mechanisms to fund the cost of the options selected? Finally, the report says that this
A
combination of options would meet the needs of the urban area through approximately 2030, allowing
adequate time to monitor and select future longer term measures. He asked what continued effort is
@
planned to study and pursue the longer term measures the community will need beyond 2030 to satisfy its
water needs. Mr. Rooker said he hopes, as part of this process, that a formal mechanism will be put into
place to explore and vigorously pursue the longer term options.
Mr. Collins said he will see that these questions are addressed after all of the speakers have been
heard.
Mr. William Orr said nothing has been said about the Buck Mountain Reservoir, so he wonders if
that project is still on the table and will be built. He said that the flow in the Rivanna River on a day-to-day
basis is lower than what it used to be. Yet, when there is a rain, the level rises promptly and for a couple of
days, it is way up. He suspects that is the result of development and the impervious surfaces created. He
wonders why we are looking at entrapping water before it gets to Charlottesville and not some way to catch
the overflow when there is a crest after a rain.
Mr. Timothy Hulbert said he lives in the City. He works for the Charlottesville Regional Chamber of
Commerce representing 1400 businesses, who employ 45,000 people in the community. He
complimented the Mayor and Chairman Thomas on the excellent work product of the consultants. He was
given a copy of the report earlier and found it to be a well done product. It lays out a number of alternatives
for what should be done with the communitys most precious natural resource. His personal perspective is
=
that the recommended immediate actions are logical, reasonable, environmentally-sensitive and
affordable. All should embrace conservation, no matter how much there is of a resource. He thinks the
other things make sense: alternate release, reduce sedimentation in a reasonably efficient way, and
addition of the four-foot crest controls. That is his perspective, not the Chambers perspective. He is not a
=
big fan of dredging. He understands it has to be done on a regular basis. He comes from the Upper
Hudson Valley which is looking at A nightmare regarding dredging. It is a sloppy, Herculean, atrocious
chore. It is something he does not think should be in the first round of options. He said the Chamber will
engage its public process. They have done some interviewing, some research and some analyses. They
will engage their Government Affairs Committee and ultimately their Board of Directors. Later in the year,
they will share with all what they think in an official and formal way.
Mr. Lindsay Dorrier said that in listening to the remarks, he thinks the governing bodies are lucky to
have so many fine people testifying about water. It appears that everybody takes water for granted. The
question is, how much is spent, and how is the money directed? From his standpoint, he thinks the area is
fortunate because it has an abundance of water, and there are new ways to get more. The plan that has
been developed has new reservoirs proposed, and it is a question of which ones to implement and when.
He thinks that out of the group assembled tonight, the political bodies should mobilize this group,
coordinate it and come up with a recommendation for a plan of action that moves into the next 50 years.
His question is one Mr. Rooker brought up about how much money the community is willing to spend.
Everything cannot be done at once, so it is a question of allocating the funds and moving ahead with the
project on a piecemeal basis. Fixing the SFRR seems to be something all agree needs to be done, so it is
a question of when and how to do it. He thinks that should be the first priority. The new sources of water
would come into the plan later in the 50-year period. He does not see the system as being broken right
now. If you want to prevent future problems, it is a question of how much money will be spent, and nobody
has talked about that.
September 27, 2001 (Adjourned Meeting)
(Page 8)
Ms. Ann Lederer said she lives on the SFRR. She is one of a small minority of people who are
affected. There has not been a lot of discussion about the impact it will have on people who bought land
there with nothing in their deeds about impoundment and nothing on their dock permits about losing their
docks and boat houses. She has heard nothing about the cost of resurveying their land if they lose some of
it. Who will pay for it? It seems unfair. It will affect their real estate taxes. When some of the houses were
built, and in some cases, not by the present owners, the setback provision was 125 feet. She understands it
is greater now, but those who live there were never notified of any change. Should those setback provisions
be grandfathered so if they need to change the footprint of existing houses, they can do it. There are other
costs she has not heard mentioned this evening. There are two bridges which will be affected, one over
Woodland Road which does meet VDOT standards at this time, and the other is a bridge over Earlysville
Road. Will these be hidden in a VDOT budget when the change is needed? She said there will be an
impact on the wildlife in the area. She asked that the concerns of the present landowners not be ignored
even though there are few of them.
Ms. Katherine Jordan said she is a planning student and a resident of Albemarle County. Given the
fact that a large portion of the North Fork Rivanna River watershed lies in Greene County, are there plans to
work with Greene County now or in the future?
Me. Bruce Appleyard said he is the Transportation Land Use Planner for the Southern Environ-
mental Law Center. He said SELC believes that conservation and the enhancement and protection of the
existing water supply should compose the foundation of any plan for the future of the communitys water
=
supply. At the November 18, 1999, forum, SELC spoke to the Board of Supervisors, the City Council and
RWSA, and urged that an effective plan for water conservation be developed. They support the drought
management and conservation alternatives in the report and urge the two governments in conjunction with
the RWSA to develop and adopt a comprehensive water conservation plan. They also urge the Board, City
Council and the RWSA to take A close look at the projected demand for water. The effectiveness of better
land use practices and lowering demand on the water supply need to be taken into account. They urge
these bodies to protect and enhance the existing supplies including the SFRR and Sugar Hollow Reservoirs
before moving ahead with construction of, as it is referred to in a rather simplistic and sanitized fashion,
new water impoundment.

Mr. Kevin Lynch said he is a member of Charlottesville City Council. He wanted to ask a question
of the dredging expert. He wonders if the costs of dredging in the past have tended to go up or down. With
technology getting better, is there a decrease in the costs? He is concerned that even with the crest
controls, only a little time is being bought. Could this time create a less expensive solution later, or is it likely
to be a more expensive solution? A second question, for those communities which have decided not to
dredge, what have they done with their expended reservoirs?
Mr. Collins asked if anyone else from the public wished to speak. Since there was no reply, he
suggested that the list of questions imposed tonight be discussed. There is the question about dredging
costs, a question related to the land impacts on the reservoir if the proposal goes forward, a question about
bridges, a question of setbacks. He suggested that the technical issues be discussed first. He asked if the
impact of the proposed four-foot crest controls on the landowners and those whose properties abut the
SFRR have been taken into account.
Mr. Potter said when the City purchased the land for the SFRR back in the mid-sixties, theoretically
they purchased a take of up to elevation 387 feet. The spillway of the dam is at elevation 382.
Theoretically the City of Charlottesville owns a ring of land around the reservoir that would be defined by
projecting the existing water level five feet higher and extending it out horizontally. He says theoretically
because he knows from the experience of a local surveyor who was involved with that take a number of
years ago, that there are some areas of the reservoir (not in the vicinity of the Earlysville Road bridge)
where the land flattens out enough that the horizontal projection of that five foot vertical ring would go so far
removed from the reservoir that somebody made the decision that enough is enough and said we will
A@A
draw the line here. He does not know where those lines are. It is his opinion that some additional land
@
would have to be acquired.
Mr. Collins asked if there is an estimate for this additional land in number of acres. Mr. Potter said it
has been estimated to be less than 100 acres. That actual determination would not be made until after a
decision to go forward with that particular alternative. The other part of that is, in the event of a flood event,
the advantage of a bladder type crest control is that it would be collapsed so regardless of the storm event,
the reservoir would revert back to its existing spillway elevation of 382 feet. The crest control would not
result in the flooding of any additional land.
Mr. Collins asked Mr. Potter to address the question of whether bridges would need to be replaced
if this option is chosen. Mr. Potter said it is possible that the bridge crossing Ivy Creek would have to be
replaced. They have talked with VDOT about this, and VDOT has requested an engineering study of the
bridge. At this time, no determination has been made.
Mr. Collins asked if the bridges have to be elevated, who would pay that cost? Mr. Potter said he
thinks the determination of who will pay will depend on why the bridge is being raised, its remaining usable
life, and a number of other factors. Given the slowness with which VDOT is perceived to move, if there
were urgency in getting this done, RWSA would probably have to pay for it with some expectation of
reimbursement. In reference to the question of the boat docks, these docks exist on the reservoir at the
pleasure of the City and the RWSA. Permits are issued for each of the existing boat docks with the
September 27, 2001 (Adjourned Meeting)
(Page 9)
understanding that should future plans call for a change in operation that would result in the removal of the
boat docks, that is the homeowners experience. As far as the setbacks are concerned, that is a County
planning matter, and he cannot address that question.
Mr. Collins said there are other possibilities. A speaker mentioned the possibility of conservation
easements. Also, cost-sharing programs or other types of programs could be introduced to move setbacks
and possibly compensate for any additional setbacks. This is all speculative. As to Mr. Lynchs question,
=
on the average and over the long-term, have costs declined or increased for the type of dredging
mentioned?
Mr. Pound said dredging costs have increased over the years, as is the case in almost every aspect
of the economy. There have been significant cost increases over the last 26 years in which he has been in
this business. Technology has improved somewhat, but overall, dredging has not changed much in the last
20+ years. There are several methods of dredging. There is mechanical versus hydraulic. There are
different kinds of mechanical and different kinds of hydraulic. Mechanical dredging would be more
expensive than a hydraulic method in this particular project. He would like to point out that hydraulic is
much cleaner than a mechanical method. The mechanical method would require a barge-mounted
excavator or a cable-arm crane and the bottom is dug out mechanically, the material put on a barge, taken
to shore, off-loaded, de-watered, and then transported somewhere else. Every time the material is handed,
it increases the cost. Also, with mechanical there is a lot of mess, and a lot of turbidity created. That can
cause secondary problems on the water treatment facility downstream. For the hydraulic method, there
are two forms of hydraulic dredgers. One is called a cutter-head dredge, and the other is an auger-type
dredge where the cutter-head looks like a large snow blower. The auger-type dredge can draw the
material mechanically to the center at a much slower rate which causes less turbidity, and then it is sucked
up like a vacuum cleaner. The cutter-head dredger has a basket with teeth which spins around, and the
syntrophical force throws a lot of material out which causes more turbidity, but both methods are cleaner
than mechanical, and usually they are more cost-effective because the material is dug one time at the
dredge site with it being pumped directly to the containment area where it is then de-watered and stored.
As far as methods are concerned, hydraulic is historically cheaper, but prices have increased over time.
Mr. Collins said he saw some hands raised by people who want to discuss this further. He will
exercise his prerogative to leave the dredging issues for the moment because there are bigger issues on
A
the table. He asked Mr. Potter to discuss any technical operation issues he may have. Then, bigger
@
questions about money, what process will follow this meeting and what to do about the term beyond 2030
will be discussed next.
Mr. Potter said he will discuss some of the questions asked. Ms. Jordan questioned the impacts on
the North Fork Rivanna watershed. He said at present there are no plans to do anything in that watershed.
The improvements at the SFRR would not impact the North Fork Rivanna watershed. There was a
question from Mr. Orr about a reservoir in the southern part of the County. He said the Buck Island Creek
reservoir was an alternative looked at. It had a relatively high cost compared to Alternative 1
because the water is not in a place where the current demand is located, so it would require pumping,
transmission lines and a water treatment plant. It was estimated to impact approximately 20 existing
structures, and there were other issues.
Ms. Thomas said there was also a question about where the Buck Mountain
Creek reservoir project stands now. Mr. Potter said reservoirs are out of favor from a permitting standpoint.
In this instance, given that there are less environmentally-impacting practicable alternatives, the chances of
getting a permit for a new reservoir would not be favorable. However, the current implementation of
recommended alternatives only carries the area through the year 2030. Unless demand can be decreased
or the attractiveness of dredging improved, other alternatives will look different in the future. The Buck
Mountain reservoir may be one of those other alternatives.
Mr. Collins said he will respond to the basic question of what will happen now, and what are the
succeeding steps. He said the RWSA is the wholesale distributor of water. It is an independent legal agent,
but it is politically responsible to the City and the County who created it for their joint needs. The
consultants report and the recommendations seen this evening are still under discussion by the Board of
the RWSA. What has been heard this evening, along with other information, will be taken and considered
further. If and when they decide to accept these recommendations, they will then recommend them to the
City and the County for consideration. The City and the County would then undertake their own processes
of deliberations. Both the time and the process are uncertain in the sense that it is not known when a
decision will be made to go forward with these recommendations.
Mr. Caravati asked what kind of a schedule the Supervisors have. Mr. Collins said he believes a
tentative schedule was adopted by RWSA to try and make some sort of a recommendation by next month.
Whether that schedule will be maintained will depend on how what has been said this evening is assessed.
There may be other factors they want to discuss. It could be as soon as one month, or considerably longer
depending on how the RWSA responds to the information provided, and what they hear from the City and
the County as to what they want to see.
Mr. Collins said there is the question of money and financing in general, and perhaps of cost. This
may not have been adequately addressed from the standpoint of members of the audience. The first
question has to do with money. How would the costs have to be paid? How much would it cost? He asked
the estimated cost of just the bladder and four-foot crest controls.
September 27, 2001 (Adjourned Meeting)
(Page 10)
Mr. Potter said he does not have those figures tonight. He will look to Mr. Brent and Ms. Mueller for
an answer, but he is not aware of any funds for any of the alternatives other than the urban water users rate
structure. There may be some grant money somewhere for issues such as sedimentation and dredging,
but as far as the bladder and other capital type improvements, they will have to be paid for by the urban
water users in the form of the operating budget, or by long-term debt. He said this is a project which was
not envisioned when the RWSA was formed, so who pays what as far as the shares by the City customers
or ACSA customers has to be negotiated.
Ms. Collins said the costs are not known for that alternative at this time. However, it is assumed
that those costs would most likely be paid out of the water charges made to those properties connected to
the system. Ms. Mueller just pointed out that the agreement between the City, the County and ACSA does
not set a criteria or a standard for sharing these costs. The respective shares to be paid by the City users or
the County users is something that would be settled through discussion among those two bodies and other
parties.
Mr. Collins said normal costs associated with existing facilities, or negotiated at the creation of the
RWSA, are settled ad hoc by the RWSA Board in consultation with the City and the ACSA. The ACSA is an
independent organizational entity within the County, and the relationship between that Authority and the
Supervisors is one that is managed by those two parties. Mr. Potter said the ACSA Board is appointed by
the Supervisors, so that is the relationship of the entities. Mr. Collins said there is no standard established in
previous agreements that would cover the unusual capital expense of creating a new facility.
Apportionment of that cost would have to be negotiated, and there might be differing views about that
apportionment.
Ms. Thomas referred to a hand-out entitled Appendices which contains a Water Supply
A@A
Alternatives Matrix on which is listed the estimated costs of the various alternatives. She said the way the
@
Buck Mountain watershed land was paid for opens a different possibility. The money all comes from the
water users though rates, but, in this case, a surcharge was added to the fee for an initial hook-up of a new
unit. That puts the burden on every new dwelling unit, so that will be a part of the discussion of how to pay
for it all. In previous years, the Federal government picked up a large portion of the costs of public utilities,
such as the Crozet Interceptor. That money is no longer available. In some communities across the U.S.,
water is one of the most expensive things a homeowner has to pay for.
Mr. Dorrier asked if it would be appropriate for this panel to establish a joint City/County task force
of affected people in the community to deal with the financial aspects of this question. Mr. Collins said that
at some point, that will have to take place.
An unidentified gentlemen asked if the hook-up fee is still being used to pay for the land at Buck
Mountain, or has that debt been retired. If it is not being used for that purpose, is it going to the ACSA or the
RWSA. Mr. Bill Brent said the agreement where the City and the ACSA agreed to acquire the Buck
Mountain property, required a connection fee on new connections in both the City and the County. They
collect that as the collecting agency, and the money is passed to the RWSA. Mr. Collins said the Buck
Mountain property was acquired with the expectation that that would be the next additional water supply
when it was appropriate. The consultants, VHB, were told it was unlikely that Buck Mountain would be
approved in the time period they would like because of Federal and State reviews of new reservoirs and
their effect on wetlands and endangered species. There was some evidence that an endangered species
would be affected by Buck Mountain and also a lot of wetlands acreage. The standard Mr. Potter
mentioned for the planning process (least environmentally-impacted alternative) was one the consultants
looked at. They came up with the option for the bladder instead of proceeding with the Buck Mountain
option. The land that was acquired for Buck Mountain is still in the ownership of the RWSA. Mr. Brent said
it was a 30-year bond issue, with the bonds being issued in 1981.
Mr. Tom Jones said he lives in the County near the SFRR. He said in the original matrix there were
two line items listed for the dredging option. A single event was listed for $71.0 million, and annual
dredging was listed at $7.2 million. He was not sure whether those are two separate alternatives, or if the
single event happens three times between now and 2050. Mr. Potter said there are two alternatives listed
for dredging. First, a one-time event to restore the reservoir to the level that existed in 1996, which would
result in a safe yield of 7.2 million gallons a day. The second approach is for multiple dredges over the 50-
year planning period. The cost of either approach is approximately the same. Mr. Thomas Downing with
OBrien & Gere has said there are a number of different options for the dredging alternative. First, they
=
looked at the option of dredging now, dredging in 2030, and then dredging at the end of the period to
restore the reservoir to its original volume each time. They decided that was not necessary just to find out
the effects of this on the watershed. They can monitor the effects of sedimentation on the reservoir to see if
what has been occurring since 1966 continues to occur. Due to new technology, the 1994 bathymetric
survey and the most recent survey can be compared closely since the cross-sections were taken from the
same locations. That data can be compared on a one-on-one basis to see what the actual sedimentation
rate has been. In short, they looked at a couple of different options. If the reservoir were dredged on a
one-time event, they would know what sediments had accumulated since 1966 to the present time. There
will be a larger volume of sediment in the reservoir when the one-time dredging event occurs in 2030. At
that time, the reservoir will return to its original yield in 1966 of 7.2 mgpd. Another approach was to have
annual dredging where each year an increment of sediment was removed that would yield a safe yield of
7.2 mgpd. There are a couple of different approaches, and at the end, there is a 7.2 mgpd safe yield in
2050. There would be a large, one-time capital investment for the one event, or an annual dredging cost.
September 27, 2001 (Adjourned Meeting)
(Page 11)
Mr. Murdoch asked if there is any commercial potential for what comes at the end of the dredging
process. Mr. Pound said there could be some chemicals in it that would make it unsuitable, or the grain
size is unsuitable. If there were a material which is suitable, the problem is the quantity being discussed.
There is a potential use of the product, but it depends what the product is, and the availability of it at the
time.
Mr. Hermsmeier said when the SFRR was originally constructed, it was known that it would
accumulate silt, so he wonders if there were a contingency plan put into place at that time. Mr. Potter said
there are two, three-foot sediment control gates built into the face of the dam. He thinks the structure was
intended to release sediment as it moved toward the dam face.
Mr. Lynch asked if there will always be a minimal level in the SFRR. Mr. Potter said the engineer
used zero as a 2050 safe yield of the reservoir because that was the most conservative and defensible
number for him to use. There is no way for him to predict now what the volume of the reservoir will be
because of all the variables. As the reservoir fills in, the detention time will be less, therefore the velocities
to move the same amount of water through it will be faster, and some of the sediment settling out will be
scoured out in the future. Where that equilibrium point will occur, he cannot predict. He thinks there will
always be some capacity available in the reservoir, but he does not know what that number will be.
Mr. Collins asked if everyone who wished to speak had done so.
Mr. Jason Hulbert asked the amount of per capita water consumption. Mr. Potter said it is
approximately 120 gallons per capita per day, but that depends on whether looking at the City, the
University, or the County. He does not how this ranks against national figures. He would not try to compare
the local number against other localities because the local number includes all uses.
Mr. Collins said there is a dispute about what number should be used for an average. In looking at
some of the responses from agencies such as the EPA and other organizations which are interested in
water policy and water supply, this locality will not receive the scrutiny that it would if trying to build a new
reservoir. Newport News is trying to build a new reservoir. The analyses demands they have to meet is
quite different from the review that has to be undertaken by the RWSA. Whether that is an advantage or a
disadvantage, he cannot say.
An unidentified gentleman said he appreciates all the work which has been done. He said a lot of
time was used discussing dredging, but little time was spent discussing the bladder. He would like more
information on that. Mr. Potter said he would be happy to provide a copy of all the information he has which
was developed for this report. Mr. Collins said they will contemplate a variety of ways to respond to
individual concerns expressed tonight. He thanked all who attended this meeting tonight.
At 9:10 p.m., the meeting ended.
