The first Saturday in October that you can stand outside at nine in the morning without sweating, half the town has the same idea, and a good part of it ends up at the Nature Center. You pay the few dollars at the gate. You leave the dog in the truck, because the rule is no pets past the gate unless they are working, and the rule is for the birds. And you walk out onto the peninsula, past the ponds, along the trails, with the bay on three sides of you and the plant across the water, and the air is finally the kind of air you can walk in, and the birds are coming through. This is the week the migration starts to show. Warblers in the brush, small and quick and gone. Ducks on the ponds that were not there last week. Somewhere overhead, too high to see, birds that left Canada a few nights ago, working down the coast toward the place where they will jump off across the Gulf.
It is a good place. It is one of the best places in the county to see a bird, and people drive from Houston to do it. And the whole time you are walking there, you are walking on streets.
Not on top of them. On them. Here and there, if you know to look, the trail crosses a strip of old pavement, or a curb comes up out of the grass at a right angle for no reason a marsh could have. Those are what is left of Brownwood. This was a neighborhood. It had streets with names and houses on the streets and people in the houses, and by every account it was a nice place to live, on a point of land with water on three sides, the kind of lot people wait years for. And then the ground went down, and the water came up, and after the hurricane the town stopped rebuilding, and the neighborhood became this.
I think it is the most Baytown story there is, and I want to tell it straight, because the straight version is better than any version with a lesson in it.
Start with what the ground is. Under this whole coast, for thousands of feet down, there is no rock. There is sand, and there is clay, in layers, laid down by rivers over a very long time. The sand holds water in the open spaces between its grains. The clay holds water too, but it holds it the way a sponge does, in a fine soft mass rather than in open pores. Together they make the aquifers, two of them stacked under us with names most people here have never needed to know, and for most of the last century those aquifers are where the town, the plants, and everybody else on this side of the county got their water. You drilled a well and you pumped.
Pumping changes what the ground is made of. Water down there is not just sitting; it is under pressure, and that pressure is part of what holds the ground up. It carries some of the weight of everything above it. Pump the water out faster than the rain puts it back and the pressure drops. Now the sand and the clay have to carry the weight themselves. Sand does not mind much; its grains are already touching, and it gives a little and springs back. But the clay squeezes. Water is pressed out of it, slowly, and the fine flat particles settle closer together, and a layer of clay that was a certain thickness becomes a little thinner. It does not spring back when the water returns; the particles have found a new arrangement and they keep it. Add up a few dozen clay layers, each giving up a little, and the surface of the ground, with the houses on it, comes down. Not fast. Inches a year, in the worst years. But it does not stop while the pumping does not stop, and along this stretch of the bay the ground came down several feet across the middle of the century, and close to ten in the worst places.
The town had seen this before, in a way. The Goose Creek oil field, the reason there is a town here at all, sank as the oil was pumped out from under it. Some of the derricks that had been on land ended up standing in the water of the creek and the bay. It was one of the first places anywhere that people worked out that taking a fluid out of the ground makes the ground come down. Two geologists wrote it up in a journal in the 1920s, with maps of the creek and the sunken derricks, and it is still cited. And then the town, which is not different from any other town in this respect, went on drawing water from the same kind of ground for another fifty years, because the water was there and the town needed it and the connection between a well on one side of town and a curb on the other is not the kind of thing you can see.
Brownwood was on a low point of land to begin with. When the ground under it came down, the bay, which had been a view, became a neighbor, and then a tenant. High tides came up the streets. A stiff south wind put water in the yards. Every tropical storm put it in the houses. People rebuilt, and raised, and rebuilt again, and for a while the town and the neighborhood held on, because it was home and because that is what people do. Then Alicia came in August of 1983, and the surge went through, and afterward the decision that had been getting made slowly for years got made all at once. The neighborhood was not rebuilt. The houses came down, or were taken down. The land was left.
And the land, left, did what land on the edge of a bay does when nobody is mowing it. The water made channels. The marsh grass came in behind the water. The ponds that had been low spots in somebody's yard became ponds. The brush came up, and the birds found the brush, and the fish found the shallow water, and the pelicans, which had nearly vanished from this coast in the years the neighborhood was filling up and were coming back by the time it was abandoned, found the fish. Somewhere in there the town looked at what it had and decided to keep it. It put in the trails and the gate and the small fee and the rule about the dogs, and it named it the Nature Center, and every November it holds a week for the birders. The streets are still under the grass. You are not walking around them. You are walking on them.
This town takes things out of the ground. That is what it is for. It took oil out and the ground came down and a creek full of derricks stood in the bay. It took water out and the ground came down and a neighborhood stood in the bay. It takes crude oil off the ships, now, from ground that is somewhere else, and takes it apart and sends it out as everything, and the town is careful about it in ways it was not careful before. It has a district now, made by the state, whose only job is to watch the ground and say how much water can come out of it, and most of what comes out of the tap here is river water piped in from a long way off, because the ground has given all it can. The town learned. It learned the way towns learn, which is by losing something and then not losing the next thing. And the place where it learned is now the place where it goes, on the first cool Saturday in October, to watch the birds come in.
I do not think that is irony. I think it is closer to what the rest of this series is about. Nothing is destroyed. The houses are gone, and the people who lived in them carried what they could to other streets, and that loss was real and I do not want to talk around it. But the ground did not go anywhere. It just went down. And the water that came up over it did not ruin it; it changed what it was for. A marsh is not a failed neighborhood. It is a working thing. It filters the bay. It is where the shrimp and the small fish start out before they go to the Gulf and come back as somebody's dinner. It is where a bird that is about to burn a good part of its body weight crossing the Gulf can land and eat for a few days and put that weight on. The land that could not hold a house is holding all of that, and it is doing it on the same acres, with the curbs still in the grass.
I have been saying in these essays that the town is a place where the world watches itself, on an industrial scale, in the operator on the tower reading the gauges. It also happens here, slower, with no gauges and no shift change. A town that pulled the ground out from under a neighborhood now walks out onto that neighborhood, on purpose, to look. It looks at the water it let in. It looks at the birds that came because of the water. It pays a few dollars for the privilege and it leaves the dog in the truck. That is the town looking at what it did, and at what came back, and not looking away from either.
By ten the parking area is full and there are kids on the trail with binoculars too big for their faces, and somebody's grandmother is sitting on a bench that faces the bay with the plant behind her across the water, its stacks small and pale in the dry October light. Out on the flat where the tide has drawn back, a great blue heron is standing on a square of gray concrete that used to be the corner of somebody's driveway. It has been standing there a long time. It is looking at the water, and the water is full of what it needs, and it does not know what the concrete was, and it does not have to.
