Ike Impacts on Galveston Bay Oyster Reefs

Conservation,

According to Texas authorities, at least 60% of the oyster reefs in Galveston Bay have been destroyed by the effects of Hurricane Ike. Reefs have been covered by debris and sediment churned up by the storm, and grass and other vegetation scoured from Bolivar now blanket reefs in East Bay. Similar impacts have been reported from coastal Louisiana. Combined, Texas and Louisiana produce 60% of the total domestic oyster supply in the U.S.

Certainly we are all optimistic that the oyster population will recover with time. But what if their situation is further compromised by expanded resort development on the west end of the island? For example, the proposed Marquette project proposes thousands of new homes on the west end, each with boats and their accouterments (canals, marinas, boat houses). Each boat in Galveston Bay will churn up additional sediments that are already suffocating these reefs. The USACE is now considering a request for a comprehensive environmental impact study concerning any additional development on Galveston’s west end. To ignore Ike’s impacts, I believe, would be unpardonable. Ike is the third most damaging hurricane in American history, and all involved in west end development, particularly the USACE, must recognize that fact.

See more in the Houston Chronicle. Also, read the testimony from the Galveston Bay Foundation at a recent legislative meeting in Galveston addressing these same issues.

A Burnham Plan for Galveston

Conservation, Sustainability, ,

The Galveston County Daily News (GCDN) published a guest column on December 30 (2008) in which I proposed that an urban park be created along the seawall. I suggested that automobile traffic be restricted along the seawall (such as between 25th and Stewart Beach) to let the park reconnect the city and its residents to the sea.

As expected, the column generated a flurry of comments and counter-proposals. And, not surprisingly, the article stirred up an, at times, emotional opposition (how will I get to Kroger?). When I first wrote the piece, my thoughts were more along the lines of Daniel Burnham and the 1909 City Plan of Chicago. The Burnham Plan, invested in the physical beautification of the city, established a series of parks and open spaces along the Lake Michigan shore. Apparently the example didn’t reach our founding fathers (who, interestingly enough, were faced with rebuilding after the 1900 Storm at approximately the same time). In contrast to Chicago, our “lake shore” has evolved into a highway.

There is another reason for considering such a drastic move beyond the esoteric notion of “beautification.” Presently our state and community (GLO and the Parks Board) are funding a multi-million dollar beach replenishment project along the seawall. Some 400,000 to 500,000 cubic yards of beach sand are being hauled from the east end of the island to the beaches fronting the seawall. Yet while the state and city are spending millions of dollars to rebuild the beaches, Galveston still bathes its beaches in polluted runoff from Seawall Boulevard.

Along the seawall there is no storm water retention. With every rain storm water washes pollutants off the road, onto the beach, and into the Gulf. The seawall extends well north of the paved road, and therefore the area being drained is far more expansive than Seawall Boulevard itself.

Is it possible to remake the seawall, remove the traffic, and build an urban park? Wouldn’t the removal of the pavement threaten to undermine the seawall itself? I suspect that the same technology being used in green roofs could be modified for a project such as this (an impenetrable layer covering the seawall, overlain with manufactured soil and plants). Interestingly, the present system of drains proved to be a weak link in seawall protection during Ike. Most of the damage to the sidewalk atop the seawall came from storm water undermining the pavement as it rushed through, over, and around the drains.

How would this park help our pollution problem? The park would serve as a buffer, and rainwater, percolating through the soil and plants, would either evaporate or slowly wash, without its pollutants, back to the Gulf. In a way the park would function like the wetlands that border much of the island, allowing runoff to be trapped and cleansed before it drains into the Gulf and bays.

2009 is the Burnham Plan centennial. As Chicago celebrates the occasion, perhaps Galveston can find hope in what can be accomplished with vision, inspiration, and commitment. As Chicago arose from the ashes of a great fire, Galveston can be reborn after a great hurricane. The place to begin is the nexus of the Gulf and the community – the seawall.
