Though this option would require the county to raise what
the Development Office estimates to be between $50,000,000-$114,660,000 to
purchase the development rights of the remaining open space and $137,000,000 to
outright purchase the 10,000,000 recommended in the Rural Preservation Study,
it would not necessarily be the most expensive option to the county. All the
other options will result in a need for more infrastructure: water, sewer,
road, schools, and County services that also have significant upfront costs- a
foot of water main or sewer main costs about $300 and a mile cost about
$1,600,000. There is a large capital cost to expand capacity of the H.L. Mooney Advanced Water Reclamation Facility and Upper Occoquan Service
Authority (UOSA). There is a capital cost to purchase additional
capacity from Fairfax Water and that water is not unlimited.
In the PDR option viewsheds and the current feel of the
rural area would be maintained and truly public land would be increased. The
PDR option would not increase the number of houses, students in our schools nor
the number of transportation daily trips in the coming years. There would be no
additional need for County services or infrastructure. No additional need for
teachers and schools and the capital and carrying costs associated with
increased population. There would be no
impact on sustainability and availability of groundwater to the existing
property owners.
Prince William County Planning Office Alternatives for the
Rural Area:
A-10 : 10-acre lots and rural cluster with existing density and no
sewer. This is the existing policy. In the coming years this will
result in an additional 2,783 houses being built, and additional 1,813 students
in our schools, an additional 28,108 transportation daily trips and no open
space preserved. If we continue on this
path the remaining rural areas will eventually be cut up into 10 acre parcels
with McMansions on each. There will be more traffic and a need for additional
schools and the expansion of and widening of roads.
RC-A: Rural cluster with existing density and sewer. This
alternative provides land owners the “right” to extend sewer to their
property while maintaining existing planned density levels. It would allow
development to be clustered on a corner of a property in order to preserve
greenspace and a conservation easement to be placed on the remainder of the
land. In the coming years this will result in an additional 2,783 houses being
built, and additional 1,813 students in our schools, an additional 28,118
transportation daily trips and 8,145 acres of open space preserved. This limits
the amount of impervious surface constructed which may impact groundwater
recharge less than option A-10.
RC-B Rural Cluster with increased density and sewer. This
alternative provides land owners the “right” to extend sewer to their
property while almost doubling planned density levels. It would allow
development to be clustered on a corner of a property in order to preserve
greenspace and a conservation easement to be placed on the remainder of the
land. In the coming years this will result in an additional 5,067 houses being
built, and additional 3,303 students in our schools, an additional 51,177
transportation daily trips and 8,145 acres of open space preserved. The impact
on sustainability and availability of groundwater for this has not been
studied, but there would be an increased demand on groundwater and a reduction
in recharge. Both of the rural cluster
options will result in a need for more infrastructure: water, sewer, road,
schools, and County services. While there would be a preservation of some of
the open areas, agricultural parcels will continue to be chopped up.
TDR-A: Transfer of development rights using density based on rural
character areas of the rural preservation study. In a TDR program a
landowner sells his or her development rights to a developer. This alternative
identifies “sending areas” where the rights can be purchased and receiving
areas where higher density cluster development will be built. This version of
the TDR will have the density in the receiving areas of one house per 1.5
acres. In the coming years this will result in an additional 2,643 houses being
built, and additional 1,723 students in our schools, an additional 26,694
transportation daily trips and 23,889 acres of open space preserved. The impact
on sustainability and availability of groundwater for this has not been
studied, but this does not increase the impervious surface area in the sending
areas.
TDR-B: Transfer of development rights using density base on long
range land use from the 1981 comprehensive plan. In a TDR program a
landowner sells his or her development rights to a developer. This alternative
identifies “sending areas” where the rights can be purchased and receiving
areas where higher density cluster development will be built. The basis for the number of rights allotted
to land will be based on the number of houses that could have been developed
under the 1981 Comprehensive plan. This version does not treat the
landowners of the Rural Area equally, but makes land in what was called the
“rural residential area” 39 years ago much more valuable. This option would increase the density of impervious surfaces and housing adjacent to current A-1 housing in the northern portion of the Rural Crescent significantly. The impact to groundwater recharge would be significant. This alternative will also have the density in the
receiving areas of one house per 0.4 acres. In the coming years this will
result in an additional 10,390 houses being built, and additional 6,773 students
in our schools predominately in the northern portion of the Rural Crescent; an additional 104,939 transportation daily trips and only 23,176
acres of open space preserved. Though
there would be preservation of open areas this would only be in Nokesville, the incentive
would be to convert all donor lands to farm wineries and breweries. The
receiving areas would become a high density development ribbon that runs from
one end of the “Rural Area” to the other. This would create constant traffic issues
on what are currently in many cases unlit rural roads. Residents would no
longer experience the view sheds as their view would be blocked by the wider
developed road and the super density zone. It would all appear as Fairfax style
subdivision. This option will result in a need for more infrastructure: water,
sewer, road, schools, and County services. The impact on sustainability and
availability of groundwater for this has not been studied, but this creates a
high density area of impervious surfaces around the entire Rural Area which
could significantly impact the wells of existing residents. In addition, this
increases the demand for public water which is also limited.
PDR: PDR with increase of minimum lot size of A-1. In this
alternative, Prince William County would purchase the development rights of
lots larger than 20 acres and place an easement for farming and/or open space
on the land. Though the county would not use eminent domain, the county is
using coercion by increasing the minimum lot size. This option uses public money to purchase the development rights. In
this option, viewsheds and the current feel of the rural area would be
maintained and public land would be increased. The PDR option would not
increase the number of houses, students in our schools nor the number of
transportation daily trips in the coming years. There would be no additional
need for County services or infrastructure. No additional need for teachers and
schools and the capital and carrying costs associated with increased population.
There would be no impact on
sustainability and availability of groundwater.
AAOD: Agritourism and Arts Overlay District. This
alternative can be used to complement other options. The objective would be to
allow more flexibility to establish a rural and agrarian area with agritourism
and art-related businesses. While this
will increase economic vitality, the water demands from breweries and wineries
needs to be carefully considered. Also, the operation of alcohol selling venues
along unlit rural roads must carefully be considered before allowing an
unlimited number of breweries and wineries that require massive amounts of
water.
LUV: Land use valuation. Since 1972 Virginia has allowed the
assessed value of productive agricultural land to be based on its use rather
than market value. This option envisions tweaking the aspects of this program
that the county controls- reducing the minimum acreage for agricultural,
forested and open land. The changes that
could be made would be minor to the overall tax base, but could make farming
slightly more favorable to the farmer.
Changing the character of the Rural Area to include cluster
development houses clustered in “transition areas” or even increasing the current
population could impact water availability to the existing residents and impact
base flow to our rivers. Bringing in public water and sewer connections even if
they are limited to cluster development or along what they called the transition
area, such expansion may exceed the capacity of the current water supply systems
and require water and sewer infrastructure expansion. Clustered properties
cannot rely on well and septic- they are simply too close together, clustered
development will be connected to public water supplied by Prince William
Service Authority.
Currently, public water in the areas adjacent to the Rural
Crescent is supplied by a combination of groundwater wells and surface water
supply that is purchased from Fairfax Water and Lake Manassas. There is a cost
to purchase additional capacity from Fairfax Water and that water is not
unlimited. Based on the PW Service Authority study of the Evergreen water system,
that system cannot provide adequate water to withstand a leak or to have
adequate water to recover from a problem, let alone provide supply to more
homes. In addition, piping and pumps will have to carry water from its source
to any new development. This would force the County to find additional sources
of water at greater incremental cost to all rate payers and such sources may
not even be available. In addition, water mains and sewage piping are costly
not only to build, but also to maintain.
For more than two centuries the waters of the Potomac seemed unlimited. It is
not, Fairfax Water, Loudoun Water, WSSC, and the Washington Aqueduct all share
the waters of the Potomac. The Interstate Commission on the Potomac River
Basin, ICPRB, manages the Potomac River allocation of the regional water supply
during times of low flow and plan for future water supply. The Washington DC
region has reached the point in population density and development that during
times of drought, natural flows on the Potomac are not always sufficient to
allow water withdrawals by the utilities (including power generation which
takes an awesome amount of water) while still maintaining a minimum flow in the
river for sustaining aquatic resources.
In 2018 Virginia Legislature amended the comprehensive planning
process (§§ 15.2-2223 and 15.2-2224 of the Code of Virginia ) to include
planning for the continued availability, quality and sustainability of
groundwater and surface water resources on a County level. State law now
requires that the County plan to have good quality water for all its residents present
and future in the Comprehensive Plan. These proposals do not address this issue.
The right of existing property owners to their water is primary and valuable and should not be compromised or impaired. Because there are natural fluctuations in groundwater levels it is easy to mask or ignore signs of the beginnings of destruction of the water resources that we depend on. Fluctuations in climate or rainfall and imperfect measurements and vantage points mask trends from clear view. It is essential if the Prince William County Planning Office is considering study the impact of these plans on water resources before making decisions that will result in Prince William County having inadequate water for all its residents in the future.
