Conserving
Corpus Christi Bay:
Stewardship Built by Consensus
by Pamela Casteel
from Texas Sea Grant Texas Shores, Spring 1994
Strip away the stunning miles of mansions built on the bluffs of Ocean
Drive. Subtract the thriving deepwater port, the strong military presence, the city
skyscrapers that mirror the azure of the atmosphere and crescent-shaped bay below.
Move some 500,000 regional residents and millions of visitors out of the
picture and visualize Corpus Christi when Mexicans labeled the area El Desierto de los
Muertos, or Desert of the Dead.
Stretch imagination far enough to see extinct bands of coastal Indians
fishing the bays and lagoons in boats carved from hard to come by trees. For hundreds of
years these were virtually the only people willing or able to inhabit this desolate
country of wind-whipped sand dunes, scrubby thornbushes, prickly pear, drought-parched
earth and sparse watering holes.
Passing through such uncompromising terrain in the mid-1800s to battle
Maximillian's armies prompted Gen. Philip Sheridan's legendary quote, "If I owned
Texas and hell, I'd lease Texas and live in hell."
To Col. Henry Lawrence Kinney, Corpus Christi founder, imposing bluffs
overlooking an expansive bay with a single navigable entrance looked more like a trader's
paradise.
Not a novel idea given that long before Kinney's arrival, bands of pirates
were making their fortunes smuggling contraband into and out of the refuge of Corpus
Christi Bay.
A century and a half later, Corpus Christi is the seventh
largest city in Texas centered on a 12-county Bay area population nearing
the half-million mark. The frontier port, now the deepest on the Gulf
coast, ranks as the sixth busiest in the United States.
The Desert of the Dead has blossomed into Col. Kinney's vision of building
a "Naples of the Gulf." Desolation has been paved over by development and the
vast Corpus Christi Bay system suffers from all the human interest in it.
To survive, it demands the federal, state and local attention it has
gained since its acceptance into the Environmental Protection Agency National Estuary
Program in October 1992.
"Our bays and estuaries are the life-blood of the Gulf Coast
community, providing billions of dollars in economic activity and countless hours of
recreational opportunity," says Gov. Ann Richards, who formally nominated the bay for
inclusion in the federal program in April 1992.
"The Corpus Christi National Estuary program is a wonderful opportunity to bring
the Coastal Bend community together in an effort to protect the viability of the region's
bays. It is my hope that diverse groups of individuals serving on the National Estuary
Program's various committees will be able to forge a consensus on the bay's protection
that will serve future generations well into the next century."
Congress established the National Estuary Program (NEP) through the federal Water
Quality Act of 1987 to identify and protect nationally significant estuaries. There are 21
estuaries now funded and administered by the U.S. Environmental Protection Agency (EPA),
including Galveston Bay, home of the nation's largest petrochemical complex and the
country's second most productive estuary for seafood.
The NEP requires convening a management conference charged with developing a
Comprehensive Conservation and Management Plan (CCMP) within a four- to five-year period.
The management conference assembled for the Corpus Christi Bay National Estuary Program
(CCBNEP) is comprised of anyone and everyone with an interest in the health of the marine
environment. Members include government agents, scientists, industry and business leaders,
commercial and recreational fishermen, windsurfers, environmentalists and citizens who
simply want to walk on clean beaches washed by uncontaminated water.
Hammering out an agreement among five CCBNEP committees of 220 people representing 35
different user groups is a blatant challenge that must be met to combat freshwater inflow
problems, habitat degradation, seagrass destruction, shellfish contamination, point and
nonpoint source pollution, persistent brown tide and mysterious marine mammal and sea
turtle die-offs.
Richard Volk, CCBNEP director, is well-prepared for the fireworks of opposing opinions
as to what's wrong with the bay complex, who did it and how to fix it. His experience
includes a dozen years in the South Pacific as an environmental planner in coastal
management programs for American Samoa, Tonga and the Solomon Islands. Most recently, he
was involved in developing management strategies for coastal areas of the U.S. Virgin
Islands.
"We're trying to diminish some fears about this program. One misconception is that
it's a regulatory and research program and it is really neither. It's a management program
designed to coordinate the activities of all the regulatory authorities along with input
from the non-governmental sector. We're trying to offer incentives to the citizens,
businessmen and corporate owners to get ahead of the curve, before a heavy-handed
regulatory approach is required.
"It's no different here in South Texas than in American Samoa or the U.S. Virgin
Islands or wherever people feel their land is sovereign and it's up to them to determine
how to use it. The whole concept of growth management and coastal planning is generally
new to most people. But, a quarter-century of intensive shoreline development has shown
guidelines are needed for future residential, commercial, industrial and municipal growth
to avoid further habitat alteration, pollution and reductions in fish and wildlife
populations. This isn't an attempt to take property or limit it's use, but manage it to
ensure that the infrastructure is adequately designed and constructed before new growth
actually takes place."
Volk definitely has his work cut out convincing the Republic of South Texans that
managing use and limiting use of private property are two different things. This is
war-torn country carved out of bloody battles with Indians, Mexicans and Union soldiers.
Here is the genesis of the "Wild West" complete with gunslinging cowboys on
dusty cattle drives up the Chisolm Trail. Here are the celebrated King and Kenedy ranch
empires-
This is where land owners rule.
It's also a melting-pot of people apparently capable of consensus building given the
lasting peace with Mexico and the United States.
Six months into the start-up year, the CCBNEP committees "are up and running, but
that's not to say we all have a common vision of where we're heading. We're working on
that now," says Volk. By September 1, when EPA and the Texas Natural Resource
Conservation Commission (TNRCC) begin funding development of a CCMP, the management
conference will have "at least a road map of where we're going, then we'll fill in
the street names later on."
It
will be an enormous map considering the size of the area encompassing
the CCBNEP - 75 miles of south-central Texas coastline and 12 member counties
of the Coastal Bend Council of Governments. The 550 square miles of water
includes all the bays and saltwater bayous in the Aransas, Corpus Christi,
Baffin and upper Laguna Madre systems.
Within this unique estuarine environment are the luxuriant seagrass beds of the Laguna
Madre, a rare hypersaline lagoon, and Padre Island, the longest barrier island in the
world. The bay system boundary lies between low salinity bays to the north where
endangered whooping cranes make their home and high salinity bays to the south.
Locals started worrying about the health of the marine environment a few years ago when
shrimp harvests began declining, possibly from a combination of reduced freshwater inflows
and intensive harvesting. Then came red tides and brown tides, the latter being a chronic
problem for the past four years. While fish and shellfish populations decline, the number
of fishing boats increase. Barge collisions, oil spills, ruptured pipelines pouring toxins
into coastal marshes and, on the horizon, the possibility of spills from supertankers
moving in and out of a proposed "Safe Harbor."
It all adds up to trouble in sub-tropical paradise. Water quantity, alongside quality,
is a driving issue in this drought prone area. While average rainfall is 24 to 36 inches
per year, the annual surface evaporation rate is about 60 inches. From 1931 to 1985, 96
seasons out of 216 had less than normal rainfall and 28 of those 96 represented severe
drought potential.
Freshwater inflows into the estuarine system are largely from the San Antonio, Mission,
Aransas and Nueces rivers. Freshwater from surface runoff comes from three river basins
located in a semi-arid region. Choke Canyon Dam and Lake Corpus Christi serve as the
watershed's collector points.
Compared to other Texas estuarine ecosystems, the Corpus Christi Bay complex has very
limited inflow of freshwater in proportion to the volume of the receiving basin. A
statistical trend analysis suggests that inflows declined from 1968 to 1987. The Nueces
Bay estuary particularly suffers from inadequate inflows primarily because of a lack of
natural rainfall in the watershed and increasing demand for water from domestic,
industrial and agricultural users. The shortage of freshwater into Nueces Bay became
serious enough to prompt a lawsuit by the Texas Shrimp Association that resulted in the
Texas Water Commission (now TNRCC) establishing a freshwater release advisory committee.
Whether to take precious water away from humans to support the bay's fisheries is a hot
debate that borders on the absurd, according to Corpus Christi Mayor Mary Rhodes, a CCBNEP
policy committee member.
"I speak several times a week to various groups and I'm always asked the question,
'why go out and purchase more water when we are wasting this water being released into the
estuaries?' I patiently explain that there is never going to be a time when we do not
release any water because, in order to build the Choke Canyon Dam, we were required not to
ruin the estuaries and the way to do that was by agreeing to release freshwater. We can't
turn around at this point and say never mind, we're not going to do it.
"There's still some room for movement on how much and when to release freshwater
into the estuaries, but there is just no question that we have to and should. It's a bone
of contention with some who make it into the ridiculous fight of people versus fish.
There's a real crusade group here that tries to make it seem as if we're not giving babies
freshwater to drink in order to feed fishlings."
The mayor notes estuaries are not well understood by the general public, which
sometimes thinks of them as "swamplands that are a nuisance to development. The NEP
is a good educational tool."
Rhodes says in addition to public debates over freshwater, some Corpus
Christi council members were not entirely sold on the idea of applying
for the NEP. "There was some reluctance because they were afraid
it was going to lead to a price tag at the end. I encouraged them to participate
actively in this program because it is so important. Estuaries affect
so much of our economy - not just from the standpoint that they are the
bottom of the food chain and if we ruin them we're going to become extinct
- but because they contribute so much to the recreational aspect of our
community. I basically convinced council that we're going to be regulated
anyway so it makes a lot of sense for us to have input in the process."

Keeping an environmental balance in Corpus Christi is "very difficult because we
have the industrial district smack up against the tourist industry," says Rhodes.
"We used to be an oil and gas city and that was it. Then oil and gas fell and so did
we. Our economy has become so diversified that it really has become a balancing act. We
have eight, nine equal legs holding up our economic table. I don't ever want to see us get
heavy weighted on one leg again. That's why we have to trade a little of this for a little
of that. The environmental community frowns at me and the industrial community calls me a
bleeding-heart environmentalist."
Recreational and commercial fisheries represent a solid leg of that table by having a
$364 million annual impact on the area economy. Maintaining salinity levels to ensure
productive nursery grounds is critical, but there could be better monitoring practices,
according to Wilma Anderson, executive director of the Texas Shrimp Association and member
of the CCBNEP management committee.
"We shouldn't have to release freshwater just because it's mandatory. We need to
watch the salinity levels and only take freshwater when we need it. In 1992, a lot of bays
were nearly all freshwater because of the El Nino rains. I couldn't see any sense in
dumping any more freshwater into freshwater."
Anderson adds shrimpers strongly oppose any new dredging that would disturb or destroy
nursery areas and seagrass beds. "That's mainly what we're watching. I don't think
the bay can take much more stress before it's in jeopardy. You cannot suppress it to the
point that you lose tourism or commercial fisheries that provide tremendous amounts of
jobs. Without healthy ecosystems, the shrimp industry is in trouble. If we overstress it,
then everybody is going to lose, not just one, but all."
Protecting and improving the ecology and environmental health of the bay system for
everyone directly or indirectly involved is the mission of the estuary program, says EPA's
Myron Knudson, CCBNEP management committee co-chairman.
"That may sound euphoric, but it obviously says a lot in that it recognizes there
are many users of the system from farmers to fishermen. Our goal is to integrate all those
uses so that it maximizes the benefit to all users. This is different than what has
occurred before. We're talking about how to manage the bay, which is different than the
perspective of researchers or independent groups wanting to use it for specific
activities.
"The emphasis is on how we work together as a partnership among federal, state and
local governments and the users of the bay so that everyone is aware of what's going on.
It may not be a significant cost to some users to change a practice slightly that would be
of major benefit to the bay, if they were aware," says Knudson.
He adds that the Corpus Christi Bay system was designated an estuary of national
significance "because it is a major natural resource to the economic well being of
the United States of America."
Galveston Bay, the state's first NEP beneficiary, posed a dissimilar set of management
problems, Knudson points out. "The difference is the magnitude of the number of
industrial facilities and the number of people. There are more than four million people
around Galveston Bay and fifty percent of the petrochemical capacity of the United States
is there. Galveston Bay has been insulted a lot environmentally, while Corpus Christi Bay
has been insulted some. We have the ability to see to it that it doesn't degrade anymore
and hopefully, to enhance it."
Another difference between the two programs is that the Galveston Bay management
conference had five years to draft its recently completed CCMP, while the Corpus group is
taking a more streamline approach by doing it in four. Knudson explains that EPA has
learned in the NEP process that "we were collecting too much data and should rely
more on what is existing. When Texas submitted its proposal that Corpus Christi Bay be
included as a NEP, it said most data were available. That's another reason it was chosen;
the data just need to be organized, evaluated and put in a usable system so that
government agencies and bay users can understand it and make management decisions."
What both bays have in common are highly productive ecosystems on the upside and, on
the down, a large number of endangered or threatened wildlife and loss of fertile
habitats.
"These are two of the most important public projects this agency has
undertaken," says TNRCC Chairman John Hall, who chairs the CCBNEP policy committee.
"They are about improving our economy by protecting our ecological resources. We can
have both, but not without more self-discipline and respect for these tremendous
resources."
Management decisions for Corpus Christi Bay must have a scientific basis before any
initiatives can be taken, according to Terry Whitledge, CCBNEP chairman of the
scientific-technical advisory committee and acting director of The University of Texas
Marine Science Institute at Port Aransas. While some problem areas have been well
researched, such as freshwater inflows into the Laguna Madre and Aransas Bay, others,
including changes in area wetlands, have not.
"There's a whole range of priority problems that we will try to address and these
priorities are not just defined by scientists, but by citizens, the management conference
and other inputs. The problems are checked to see if they are real or perceived. When we
finish with this management conference, we will have a plan on paper. Some easy problems,
we can start on right away, but some of the tougher problems may take as long as 20 years
to find solutions."
One mystery that may take time solving is the prolonged occurrence of an unidentified
organism called brown tide made up of single-cell algae so microscopic "you could
easily have a billion of them in a quart-size jar." While there have been reports of
brown-colored water dating back to the 1950s, it was to such a small extent that it gained
little attention. The brown tide that originated in Baffin Bay. then spread to the Laguna
Madre, has also been found along the Brownsville border at one end of the Texas coast and
Galveston Bay at the other.
"The thing that is really fantastic about this is that we believe it occurred
right after a freeze at the end of December 1989 and it has continued blooming through the
present time. We know it's a national record for a continuous bloom and may be an
international record as far as we know," says Whitledge.
After living with brown tide for four years, he says that the initial alarm has
diminished because there haven't been fish kills directly linked to it as is often the
case with the occurrence of toxic red tides. "However, there are some disturbing
things about this brown tide that we are concerned about. One is that small zooplankton
and fish larvae do not eat this organism as they would a normal plankton diet, so we're
concerned about how well they will survive without a typical food base. Another aspect is
that this brown tide reduces light intervals, which could have a negative impact on the
lush seagrass beds of the Laguna. It's not something that kills the plant right away, it's
more like taking a tomato plant out of a garden and putting it in a dim room. Some plants
just don't do well in the shade."
The appearance of brown tide may be linked to water quality, says Whitledge, and
occurrences of unusual algae blooms are becoming more prominent throughout the world.
"There's a great deal of thought as to whether we are doing something to our coastal
areas that is clearly degrading water quality."
As for the condition of the Corpus Christi Bay complex, Whitledge hedges, "On the
surface there's the perception of it being rather clean. Some measurements taken show it
to be fairly healthy. I'm not willing to put forth any comment other than to say we
haven't looked sufficiently to be very comfortable in saying we have good water and
sediment quality. We know there are trace metals in Corpus Christi Bay, such as cadmium,
selenium and zinc, that probably originated from industrial inputs. It's difficult to
explain, but I think the highest content of silver in sediments in the United States is
found in this area."
He addresses the issue of freshwater inflow by saying "We are walking a thin line
here. We want to release enough water to maintain productivity in the bays and estuaries,
but we don't want to release so much water that we're wasting it. We've got a half-million
people trying to survive off a small river that you could easily throw a silver dollar
across. When it flowed freely, it put a fair amount of water into Corpus Christi and
Nueces Bays. At the turn of the century, 100,000 oysters were harvested from Nueces Bay at
one time, now you would be lucky to find a hundred pounds.
"The urban and industrial use is fully capable of taking all the water captured in
two reservoirs without releasing any to the bays and estuaries. When the last dam was
built, there was a period of several years when there were really no water releases. A
tropical storm finally filled the reservoirs to overflowing. The tricky part of the
concept of freshwater inflow is that if you had a natural river there, with none of the
urban development around it, the river would still not release a constant value of water
because of natural cycles of floods and drought. What we have to talk about is the
percentage, the formula necessary to maintain present productivity. It would be nice to
live in a dream world and restore the bay the way it was 150 years ago, but no one in his
right mind is going to propose that.
"Let's accept what we've got and try not to let it degrade anymore,"
continues Whitledge. "I'm not just speaking of saving speckled trout and redfish -
we've got to worry about a whole lot of other things besides recreational fish. If their
food disappears, they're going to die real quick. We've got to worry about the whole food
base and we aren't currently doing that at all adequately. There is a temptation to forget
the lower parts of the food chain. In our recent studies on freshwater inflow, we're
focusing on those food items. What the scientific community is doing for the local
community in terms of the freshwater question is fairly intensive."
The Center for Coastal Studies at Texas A&M University-Corpus Christi has been
researching Coastal Bend ecosystems for the past decade. Wes Tunnell, Jr., director of the
state-supported institute and vice-chairman of the CCBNEP scientific-technical advisory
committee, says the importance of maintaining salinity levels in bays and estuaries is
poorly understood.

"So many people around here don't agree with scientists who say you have to put
freshwater in the bay if you want it to function as a natural system. They think we're
throwing water away that should be saved for people.
"We need to let people know that water is a limited resource and a certain amount
needs to go into the bay. Many people on the NEP committees are on the political and
sociological side of things and say 'oh no, we can't talk about population problems
because people won't want to come here.' I feel we need to tell the truth that somewhere
down the road we're going to have a severe water shortage problem. We may keep stealing it
from another water basin, but it's more appropriate to say up front that there's a limited
amount of water and we need to work on water conservation."
Scientists have a "pretty good handle" on the right mix of salt and
freshwater for estuary productivity, according to Tunnell, but the problem is in
"trying to convince everybody that we're not wasting water on the bays."
Tunnell, who grew up in a small San Patricio County farming community and has lived in
Corpus Christi for 20 years, is "astounded" by the increase in population.
"In the early days, there was one little causeway and now we have multilane highways
here. The city's population has jumped from 60,000 or 70,000 to 300,000. We need to have
development if we want to keep the lifestyle we have now, but we need to use common sense
with the environment. It will cost us more to develop with an environmental conscience,
but we've learned from superfund sites that it's a lot cheaper to do it up front than at
the end."
He adds that the NEP allows researchers to look at the whole picture rather than
fragmented pieces. Although many scientists are "very excited about the program,
there are some who are skeptical as to what good will come of it. It's not going to be all
fun sitting around a table having heated discussions, but in the long run, we'll shake out
what the real issues are."
Joe Moseley, a private sector environmental engineer, is a veteran of coastal planning
wars. A member of the CCBNEP management committee, Moseley has contributed to significant
legislation involving coastal Texas over the last quarter century, including the state's
first attempt at developing a federally approved coastal management program.
"Long-term freshwater supply is the single most controversial environmental issue
facing south Texas. It will be the battleground. There are those who say we're going to be
out of water by around 2015 and others who say, that's 20 some years down the road, so who
gives a damn. There is dissension even among the research community as to the appropriate
action to take regarding freshwater inflows."
Constructing a rational management plan "by its very nature means refereeing
between competing uses," Moseley adds. "The four-year NEP, hopefully, will go a
long way in coming up with more coherent and balanced uses of Corpus Christi Bay. There's
a non-frantic urgency, a need to move forward to develop better decision making
information on the bay from environmental and socio-economic perspectives.
"The program's goal is to reach a semi-consensus among a wide array of interests.
It's not going to live up to the expectations of the advocates, but it's not going to be
nearly as bad as the opponents say."
The Coastal Bend Bays Foundation, a conglomerate represented by industry, business,
academia and conservationists, is widely credited with initiating the NEP proposal. Ray
Allen, who has a master's degree in marine biology, is Foundation chairman, an
environmental consultant for Corpus Christi Central Power & Light, and a member of the
CCBNEP policy committee. He says much of the impetus for nominating the bay came from
"the impressive accomplishments achieved in the Galveston Bay NEP. We recognized that
our bays were in need of further understanding and better management."
Allen describes the Coastal Bend Bays Foundation as a non-profit, non-employee
organization "meant to bring people together who normally don't talk
to each other, frankly. The idea is for folks to discuss a common interest
in protecting and preserving our bays and estuaries. Whether they're used
for shipping, tourism or fishing, we all have an interest in healthy,
productive bays."
While the NEP also utilizes the idea of disparate groups striving for general
agreement, Allen adds, "I'll be the first to tell you that consensus building is nice
where you can achieve it, but there will be times when not everyone will be happy. We may
not agree on how much freshwater ought to be released, or how best to protect our
threatened wetlands, but we are all committed to doing that. It's just a matter of working
out the approach rather than working out the goals."
The CCBNEP, he says, provides an opportunity for locals to decide how they want the
estuary to look a couple of decades from now. "We can implement our own best
management practices to achieve our goals to the extent there may not be a need for the
hand of Washington to require something if we can take care of it ourselves."
Allen comments on the reluctance of some to involve EPA in solving local problems.
"It's a bit of a stretch to imagine that government agencies are sending us money to
develop our own management schemes without rules and regulations attached. The regulations
only occur if people don't act responsibly in finding their own solutions. There hasn't
been a single environmental rule ever written that wasn't in response to some abuse
somewhere."
Patricia
Suter, president of the Coastal Bend Sierra Club, member of the Coastal
Bend Bays Foundation and CCBNEP management committee, proudly describes
herself as a resident "eco-terrorist." The retired university
chemistry professor has lived in Corpus Christi since 1954 and says she
objects freely to whatever she wants to because "I don't have a job
where I could get fired for speaking out. A lot of individuals and some
agencies ask me if I will present an issue at a public meeting because
I can do so and no one can touch me, unless they plant a bomb in my house.
I end up saying a lot of things that I may or may not be an expert in."
Suter says the bay system "is under tremendous stress from people pressure, just
like everywhere else. We were ecstatic when we got the national estuary designation
because it meant we would have federal money to study the situation here extensively. Our
area is extremely large and all the bays are interconnected. Pollute one and it travels.
Every day we have minor oil spills each time they unload a tanker, or flush a ship's bilge
or whatever. Most of it is confined within the harbor channel, but occasionally we have
oil sheens in various places in the bay."
Waterfront development all along the path of migratory birds has led to many species
becoming endangered as their nesting sites are destroyed or fragmented, Suter notes,
adding that "people pressure is very subtle. I'm a firm believer in the fact that
we've got to react, do something very quickly or we're going to lose our ecosystem. The
balance of economics versus ecology is something we have to come to grips with. In my
lifetime the U. S. population has doubled and it's going to double again around 2060. We
have five percent of the world's population, yet we use 35 percent of its resources to
maintain our lifestyles. Corpus Christi is the second most important Texas bay for fish
and shrimp production. We have to take extraordinary measures to preserve it."
The Texas Parks and Wildlife Department has been conducting a routine freshwater
monitoring program since 1975 and the recreational fish populations "appear to be
doing very well," according to Larry McEachron, TPWD science director for coastal
fisheries. "We're concerned about the shrimp fishery and are watching that very
closely. We're seeing signs of over-fishing and if we have an increase in effort in
landings, we could have a major problem with the shrimp population."
McEachron, who serves on the CCBNEP scientific-technical committee, says the state is
working toward a limited-entry program that would reduce the number of shrimp boats
fishing the Gulf and bays.
Also high on TPWD's problem-solving list is reducing bycatch of untargeted species.
Based on recent studies in the bay complex, it was found that there are from three to five
pounds of bycatch to a pound of shrimp. On the up side, McEachron says that "some of
the ratios we've seen in some of these bays are not as high as what has been reported in
the past. That may be because of the way shrimpers are fishing or it could be they are
using fish excluder devices. Right now, we're just trying to characterize what the bycatch
is."
Mike Hightower, Texas Sea Grant deputy director and CCBNEP management committee member,
has repeatedly voiced his concern that shrimpers are taking the brunt of the bycatch
beating, while others responsible for killing unwanted fish are virtually ignored.
"If the estuary program is designed to manage and balance the use of our natural
resources, then reducing the mortality of non-targeted species must address all sources
and causes. Don't just single out the commercial shrimping industry. Characterization
studies have proven that, in addition to shrimping activities, oil and gas exploration,
toxic spills, power plants, coastal development, dredging, recreational fishing - all add
to the non-targeted taking and killing of fish, shrimp and crabs. While the average person
does not see the sources of these mortalities, with the exception of shrimpers kicking
unwanted fish off the boat, such do exist and are equal if not greater contributors to the
bycatch issue." says Hightower.
Commercially and recreationally important species found in incidental catches include
Atlantic croaker, sand and sea trout, blue crabs, flounder, and black drum.
McEachron has gained considerable experience working with the Galveston Bay estuary
program and says that although the CCBNEP encompasses a greater area, the number of
municipalities and industrial complexes is greatly reduced. "This will help the
consensus process in that we're dealing with fewer entities having to agree on where we
want to go."
Industries, "you have to understand, are nothing but people," points out
Bernard Paulson who represents the Board of Trade on the CCBNEP policy committee. The
Board of Trade, an association of 16 port-using companies, supported efforts to gain NEP
status.
"We reside here. We like to fish and spend time on the bay. Most industry is
permitted to discharge into the bay that we use for shipping or water supplies. We have a
very definite interest in a healthy bay."
Paulson says after oil and gas production bottomed-out in the 1980's, employment on the
processing side of the oil industry and chemical refining plants surged upward.
"We're a big player in the economy of Corpus Christi, affecting about half the
employment in the area. Tourism is very important, but it doesn't come anywhere near the
economic impact of industry.
"I don't know if you've been to many ports in the world, but Corpus Christi is
probably the cleanest port you'll find. Industry has been very responsible here in helping
keep the bay clean. Corpus Christi also meets all the air quality standards. A couple of
years ago, a group from Venezuela came here to see how industry and tourism prosper side
by side."
Paulson is chairman of the Safe Harbor committee studying the feasibility of developing
a deep draft port for Texas that could deliver "a couple million barrels of oil per
day" to the refineries through nearby barrier islands. "I thought this was a
very good project because incoming ships would be in an enclosed berthing and if there
were a spill you could contain it right there. The environmental community has always said
that they thought an offshore mono-buoy, where you tie up a ship and pump the oil through
a pipeline to shore, would be better. A few meetings ago, although I'm a firm believer in
the way Safe Harbor was conceived, I recommended that the primary project should be the
offshore mono-buoy."
His recommendation was based on a lack of product support from Houston refineries and
those in the mid-continent, plus the offshore mono-buoy could be constructed for about
half the $300 million price tag attached to Safe Harbor. The mono-buoy would be a smaller
operation that "could handle our local refineries with not too much capacity left to
go north. If industry does go to the offshore mono-buoy it will make the environmental
community feel better because we're not bringing oil into the bay system."
Two other area industries that have historically kept the economy strong are ranching
in the southern counties and agriculture to the north. The Corpus Christi Bay Estuary
ranks fourth out of 92 U.S. estuaries for the amount of agricultural acreage in the
watershed, which means there's significant potential for nonpoint source pollution from
fertilizers, pesticides and sediments.
J.F. Welder Heirs, is one of the oldest family-owned farming and ranching companies in
the area. Nonpoint source pollution from agricultural runoff is a key issue that "the
agricultural community is interested in doing what it can afford to do to correct any
problems there might be," says Roger Welder. "However, our most important
concern is that the data on which recommendations are based are accurate, that good
science is applied in determining what problems exist, if any. That on the front end is
going to be the most important role that agriculture wants to see played out. If we locate
some problem areas, let's find workable solutions that are affordable and meaningful. My
first hope is that farmers and ranchers can come up with solutions of their own and are
not regulated into a corner."
Welder, like anyone in private industry, has "a healthy fear of governmental
bureaucracy. This estuary program is very well represented by government agencies - I'm
the only voice on the management committee that agriculture has and we have the potential
of being impacted pretty heavily. There is some concern that we're not being represented
locally or nationally. As the large metropolitan areas grow, people congregate in those
areas where all the issues are formed and voted on. The rural communities that control
most of the agricultural resources have very little representation at the state and
federal level. Some regulations are politically motivated and are intended to get votes
and press more than actually correct a problem. This agricultural runoff is a real popular
issue right now. Municipal wastewater discharge, which can sometimes have a much greater
impact, gets some press.
"News travels around in farm publications that agricultural runoff is sometimes
measured inaccurately, so there's a fear of poor information more than anything else. If
the farming and ranching community is satisfied that the science is correct, they won't
have any choice but to look for solutions to the problems."
Farm and ranch practices have been forced to change over the years primarily because
these industries are hard-pressed to survive, says Welder. "Ranchers have had to
improve grazing management to enhance the environmental quality of the land. Farmers have
certainly had to learn to do more with less dollars and economics is the driving force
behind a farming decision. A farmer's not going to invest in a pesticide or fertilizer
that's not absolutely required for him to make a profitable crop. The Food and Drug
Administration pulled a lot of chemicals off the market that have a negative impact on the
environment and those that are available are extremely expensive and used at a bare
minimum."
Reversing environmental damage by changing the way we do things is at the heart of
another burning issue facing NEP committee members - the raising of the John F. Kennedy
Causeway held responsible for choking off water circulation in the Laguna Madre.
The 4.4 mile stretch of causeway, formerly known as the Padre Island Causeway, links
Corpus Christi with Padre Island. It opened in 1950 to replace a wooden bridge erected in
1927 and is mostly fill that limits water exchange into the Laguna Madre and compounds
hypersaline conditions. It is blamed for the lingering brown tide in the Laguna Madre that
threatens shallow seagrass beds and for the drastic reduction of marine life in the
waterway.
The causeway also presents a human health threat in that low elevations of five or six
feet are prone to flooding and pose serious threats to hurricane evacuation for Padre
Island, Mustang Island and Port Aransas residents.
In response to these concerns, the Texas Department of Transportation has funded a
$300,000 study to explore options to resolve safety and environmental issues. A premature
estimate for elevating the causeway and expanding the number of traffic lanes from four to
six is around $75 million.
Bob Wallace, attorney, board of trustees member of the Coastal Bend Bays Foundation,
and CCBNEP management committee member, says "There is no doubt that we are going to
raise the causeway. The community won't pay for it, the federal and state government that
built the highway in the first place will pay for it. They just love to hear me say that,
but I think they understand where I'm coming from.
"The Texas Department of Transportation proposed to build a new highway to the
island that would elevate one side, but would basically leave the dam in place and the
environmental community went ballistic. The Bays Foundation volunteered to be the point
organization to create a better plan."
Wallace explains that even at low tide, Kennedy Causeway may not be more than a few
feet above sea level at its lowest point. "Even without a storm event, water can
literally cover the whole causeway. That happened a couple of years ago and people were
stuck on the island. My opinion is that if we move the problems we've created, nature will
fix itself. That's what's ironic about the Kennedy Causeway, Hurricane Carla removed the
whole thing for us, then we were smart enough to rebuild it."
The NEP will prove invaluable, Wallace notes, because "it's going to create a
whole different level of communication that hasn't existed in this part of the world
before. People in this community are trying to find solutions - and I don't mean solutions
where we tell businesses they can't operate - but where business flourishes in a fashion
that is not detrimental to our environment. If we use that as our focal point, we're going
to have a plan for our system that will be beneficial to all concerned.
Four years from now, the committees of the CCBNEP will have grappled with management
solutions for a list of serious environmental problems unique to the area. Alongside
freshwater issues, industrial and agricultural practices, brown tide and water circulation
troubles, wetlands are disappearing at an alarming rate.
The Texas Parks and Wildlife Department estimates that 35 percent of the state's
coastal marshlands were lost between the mid-1950s and 1979. The wetlands of the Corpus
Christi area are some of the most varied in the state with more than 20,800 acres of
emergent wetlands and 46,720 acres of grass flats. Wetlands and submerged seagrasses are
home to a wide variety of wildlife and several endangered species of migratory waterfowl.
Ninety-five percent of the commercial and recreational fish-species caught in the Gulf of
Mexico are spawned in estuarine ecosystems.
Coastal wetlands purify water by trapping or transforming pollutants, sediments and
nutrients. Their cleansing function is critical in urban and agricultural areas where
runoff is heavily loaded with sediments. Marsh plants serve as filtering systems by
removing nitrates and phosphates from waters that receive treated sewage.
Wetland loss can be attributed to natural causes, including increased sea level,
saltwater intrusion and storm erosion. Humans inflict abuse through pollutants, dredging,
waterfront development, dam and levee construction, and extraction of groundwater, oil,
gas and minerals that can accelerate subsidence.
There is a clear and present need to correct environmental abuses of every sort to
protect a bay system of obvious ecological, recreational and economic importance to Texas.
Corpus Christi, the largest city in the Coastal Bend area, attracts 2.8 million visitors
annually. In 1990, tourism generated $480 million in local spending, a whopping 37.1
percent over 1989's $350 million. By 1991, that number leaped to $530 million, resulting
in an average annual economic impact of $1.3 billion and 10,600 tourism-related jobs.
Smaller towns in the area are often overwhelmed by beachgoers, campers, bird watchers,
windsurfers and recreational fishermen, who in 1989 spent 1.6 million hours harvesting
more than 650,000 saltwater fish.
Given the burgeoning popularity of the Coastal Bend, a "new era of
stewardship" is in order, according to Corpus Christi State Sen. Carlos Truan, known
locally as the educational and environmental senator.
"The recognition that Corpus Christi Bay and its sister estuaries are important to
the entire nation has been long in coming. It began on June 26, 1990, when a group of
concerned citizens met with representatives of the Galveston Bay Foundation, the Texas
Nature Conservancy, U.S. Fish and Wildlife Service, Department of the Interior and the
Texas Parks and Wildlife Department to plan establishing the Coastal Bend Bays Foundation.
The first job the Foundation set for itself was to seek national recognition for the
Corpus Christi Bay system."
Truan, a CCBNEP policy committee member, wants it understood that the NEP will not
replace grassroots efforts to protect the marine environment. "It will make use of
them, coordinate them and help bring these dedicated, involved people together so they can
help and reinforce all their good work."
The result will be a burst of talent and energy. People who thought they were working
alone on one small piece of the big picture will find that there are other committed
people to share their experience. The strength of this program will be based on continuing
and enhancing the fine volunteer efforts that have already made such a difference. They
are not alone, but part of a great movement to clean, restore and protect this jewel that
is the centerpiece of our lives here in the Coastal Bend."
His words of encouragement will hopefully be recalled when disparate interests gather
at the meeting table. CCBNEP Director Richard Volk is aware that some user groups are
"very suspicious, very defensive that we are going to be picking on them. However,
there is no single group, no one factor to blame. It's a cumulative impact of many factors
coming together in a synergistic way. Our goal is to identify our priority resource
management problems and to encourage people to come to the table early to help us
formulate solutions.
"Someone
recently pointed out that there isn't anyone who doesn't believe the combustion
engine is one of the biosphere's nemeses right now, yet we all drive cars.
We don't need to be defensive about that fact, it's just the reality of
where we are today. We haven't made the transition to electronic cars
and there's no regulation that says we have to. We could voluntarily purchase
one for more money and probably some inconvenience, but widespread change
isn't likely until a certain threshold in public understanding of exhaust
impacts is achieved."
Volk adds that "it takes a while for these messages to sink in, for people to say
'okay, I'm resisting change, but I still find value in it.' Eventually, there's a critical
mass of people, understanding and dialogue about the situation and it becomes part of our
value system.
"People want to make improvements in bays and estuaries and most are very happy to
have this program primarily because it is a home-grown, self-authored process. The
community will decide for itself what actions to take and how to implement them. Of
course, it will be within an overall framework of NEP guidelines."
Volk acknowledges some anxiety that the program will end up stealing from the tax base.
"That's another big challenge for us. We will work to identify a broad base of
financial support for implementation strategies. We don't want to burden any one source of
funding. We want to be creative, to get user groups to start to pay their fair share and
explore a lot of other financial mechanisms. When the federal portion of our budget phases
out, local money or money from other sources phases in.
Federal funding, he says, will go essentially toward assessment and interpretation of
existing data, then placing it in a format that can be easily understood.
"This program is about the development of a comprehensive management plan that
will be community supported and ready for implementation. Our citizens and local
government advisory committees have perhaps the most challenging and important roles to
play. Genuine opportunity for citizen participation and consensus building are the
cornerstones of the NEP process."
Within four years, users of the Corpus Christi Bay system must answer the enduring
question of how they want the bay to look in 25, 50 or 100 years.
Harder still, how will they transform that vision into reality? |
