Land
Use Change and Water Quality
Assessing the Impacts and Planning for the Future
Water
Policy Forum Sponsored by the University of Delaware
The
Delaware Water Resources Center, University of Delaware Institute
for Public Administration
Water Resources Agency, Delaware
Geological Survey, Center
for Inland Bays, and the Delaware Department of
Natural Resources and Environmental Control co-sponsored a public
water quality forum with the University of Delaware on October
2, 2003 at the University's
Clayton Hall in Newark. More than 120 people attended the
event. Lee Ann Walling, Deputy Director of the Delaware
Economic Development
Office and Special Advisor to Governor Minner was the Keynote Speaker.
This
important event brought together residents, state,
county, and local government agencies, non-profit organizations,
industry, commercial interests, students and others with an interest
in
Delaware water resources. Discussion focused on the current
status and future trends
of land use change and consequent water quality impacts. A variety
of speakers discussed a broad range of topics related
to land use and water quality in Delaware.
There
are many perspectives and challenges associated with land
use planning and water quality in our state. Ed Ratledge,
Director of the Center
for Applied Demography and Survey Research at
the University of Delaware was the first speaker of the day and
set the stage for the those who followed.
He discussed the historical perspective
and pointed to future trends of land use change in Delaware. His
presentation included eye-opening information,
including population growth and housing development trends. We
learned that:
- The
number of acres of farmland is decreasing. Delaware
had around 900,000 acres of farmland in 1920. Now we
have about 580,000 acres in the state. Famland acres
are projected to continue to decrease until we reach about
380,000 acres by 2030.

- The
number of housing units in the state is increasing,
but there are fewer people living in each unit today.
- Every
2 person household requires approximately 1.5 acres of land.
This figure includes living space plus work space, rights
of way, shopping, etc.
- Middletown
and the Appoquinimink watershed is currently the area with
the most growth in the state.
- The
average commute in Delaware is 20-24 minutes. Only about
3% of people use transit and most commuters drive
alone rather
than
carpooling.
Following
Ed Ratledge’s opening presentation, Dr. Tom Sims,
Director of the Water Resources
Center, moderated four speakers
on the current status of and major challenges for
Delaware’s
water quality.
Kevin
Donnelly, Director of the Division
of Water Resources for DNREC
presented an overview of the state basin and the multitude of
water quality problems we see in Delaware today. He talked about
the 2002
305(b) Report,
development and land use in the Appoquinimink watershed, public
health protection areas and activities, and the extensive volunteer
water monitoring network in Delaware.
Dr.
John Mackenzie, associate professor in the Food
and Resource Economics Department at the UD
College of Agriculture and Natural Resources, continued the discussion of the status and challenges
for water quality by discussing the trends in agricultural land
use and water quality challenges faced by agriculture. He
talked about the range of environmental benefits provided by land
protection, pointing out that water quality and habitat
quality seem to be secondary, compared to other concerns
people
have, such as the visual quality of land.
Scott
Andres, a senior scientist with the Delaware
Geological Survey,
discussed how
mapping groundwater recharge areas is important
for state and local land use plans that address water quality.
His perspective is that groundwater and surface water contamination
are usually directly related to land-use. he also believes
that “excellent
recharge areas” should be afforded higher protection status
because contamination in such areas can create major impacts
to our groundwater supplies and quality.
Dave
Athey, from URS Corporation, works
with DelDot on
Phase
II of the NPDES Stormwater Program. He talked about
how stormwater management programs in Delaware, along with current
and planned activities by DelDOT, involve efforts to develop
land use plans that protect and improve water quality.
Direct and indirect impacts of roadways included in additional
development and changes to watershed hydrology are important factors
in our future. He mentioned factors that can be controlled,
such as paved areas,
drainage methods, and the traffic amounts. Planning in these
areas help mitigate uncontrollable factors, including precipitation
levels and receiving waterway characteristics.
Connie
Holland, Director of the Office
of State Planning and Coordination, spoke about
the state’s
effort to link land use and water quality. She discussed House
Bill 255, which
states that municipalities must have a comprehensive land use plan
that protects and improves water quality. She also covered
OSPC's role in Livable
Delaware, established
by Executive
Order 14,
and the passing of the PLUS
bill.
Speakers
in the following session,
moderated by Jerry Kauffman, Director of the Water
Resources Agency, discussed local perspectives
about the link between land use and water quality. Speakers
were Charles Baker, New
Castle County Department of Planning;
Hans Metlarz, Kent County
Department of Public Works; and Bruce
Richards, Director of the Center
for Inland Bays. They
covered current and planned county-level efforts to develop comprehensive
land use plans to help improve and protect water quality.
Charles
Baker talked about property rights issues, flood plains, and
the “Environment
First” ordinance implemented by New Castle County. He
suggested that responsibility for water resources should
be
combined in Delaware; currently water resources responsibility
is fragmented amongst state, county and municipal
agencies.
Hans
Medlarz talked about Kent County’s investment
in sanitation services, including $14 million for new transmission
lines and pump stations to improve service.
Bruce
Richards closed the day by with his discussion about property
rights issues, especially those surrounding property values
in Sussex County.
As we
move forward, there are many complex issues surrounding the question
of how to best manage coming changes for Delaware. Your
participation in the process is valuable to your neighbors and
the rest of us, and we look forward to taking part with you now
and in the future.
