I am going to tell you ...a story. It is
a personal story about Tamalpais Valley and its smaller cousin,
These two valleys and the hills which surround
them are watersheds. Once they were my home, and I cared very much for
them. Whether or not you are interested in these small parts of southern
Marin I hope you will listen to what I have to say, because you, because
everyone in Marin, because everyone in the entire world lives within a
watershed, and you may learn something of the responsibility which this
Though I was born in San Francisco, my
life really began in Tam Valley. I was born the wrong person for the city.
As a youngster, I was fascinated with the snails in our tiny back yard
on the slopes of Twin Peaks, but I would get sick from nerves finding my
way through the busy streets to school. When I was 6 my parents located
a house on Shoreline Highway, and they decided to buy it. We moved there
in the spring of 1949 and began right away to fix up the house and establish
a garden. Across the highway was a beautiful grassy hill covered with oaks
and flowers, and through the back yard ran Coyote Creek, a small trickle
of water lined with trees and teeming with life.
I took the bus to Park School in Mill Valley
for the remainder of the first grade. My teacher was one of the best I
have ever had; her name was Edna Maguire. After school and on weekends
I had the whole new world to explore. I became interested in insects and
began collecting them, and I explored the creek which ran beside our vegetable
garden. It was a grand new life, a beginning.
In those days Tam Valley was a sleepy little
community, occupied mostly by old--time residents. I remember that one
of our neighbors had an old photograph of the valley taken around the turn
of the century. You could count the houses on one hand, but the hills were
bare of trees. Even then I could see that the ravages of man had
begun early, for all the trees had been stripped from the hillsides to
heat the booming gold rush town of San Francisco. I thought how
lucky I was to be living in the valley during a more gentle time when the
trees were growing back again. Yes, It is true that there were many more
houses than there had been half a century before, and a new tract called
Kay Park had just been built toward the lower end of the valley,
but these seemed like innocent changes because I was small and the hills
were immense, wild, and endless. As I grew older, I came to know every
nook and cranny.
I loved the big marsh below Kay Park; I
used to follow the creek there, then cut across into the great marshland
at the bottom of Tennessee Valley. From there I would strike out into the
fog--shrouded narrows of Tennessee Valley itself, cut across the cattle
ranch toward the coast, and swing back along the headlands toward the upper
end of Tam Valley. I had a favorite canyon there, steep and wild with great
arching bay trees. It was called Devil's Kitchen, the headwaters of Coyote
Creek, the beginning of the watershed.
I was particularly interested in the creeks
and marshes. Steelhead used to summer in a big pool next door to our house,
and the rocky bottom was filled with mysterious hydras, water mites, and
flatworms. The Tennessee Valley marsh was alive with the calls of redwing
blackbirds and tree frogs, the huge orb webs of shamrock spiders and the
head--spinning aroma of pennyroyal. Little ponds held the magic of dragonfly
nymphs, frog eggs, and polliwog. My parents gave me a copy of ANIMALS WITHOUT
BACKBONES for Christmas along with a small microscope, and I set up an
aquarium on my basement work bench. My knowledge of insects, plants, and
aquatic life grew. With friends or alone, I haunted the wild places, exploring,
learning, playing, hiking, building forts. It was a wonderful place to
be a child.
Not long after we moved, the entire marsh
at the valley's lower end was filled and another tract called Crest Marin
was built upon it. The Tam Valley marsh was a salt marsh. No one apparently
knew then that salt marshes are the richest habitats for life of
any natural community anywhere on earth, and no one seemed to notice that
salt marshes were the flood plains which absorbed the pressure of high
tides and heavy winter runoff. The creek was channeled between earthen
dikes which led the water toward Richardson Bay. One of those first winters
it rained like hell, and in the middle of the night we heard furniture
floating around in our basement.
My father was a jeweler and he worked at
home. He had his shop and all his valuable tools in the basement, and when
we went down there in the darkness of the storm we found water and mud
five feet deep with shop tools floating around everywhere in the midst
of it. The next morning, before the water had completely subsided, I rode
my bike to Kay Park, which lay a few feet lower than the new fill of Crest
Marin, and I helped people who were out knee-deep in water, scraping mud
from their homes.
As the years went by, the valley began
to change. The Mosquito Abatement District sprayed the creek more often,
and I watched sadly as great masses of dead mayfly nymphs piled up like
sand bars in the creek bottom. More houses were built at the upper end
of the watershed. Traffic increased on Highway 1, and we decided not to
get a cat or dog because of the danger of cars. Tamalpais Valley Elementary
School was built on fill placed in the beautiful Tennessee Valley Marsh,
and, as a fifth grader, I attended class there the first year it opened.
And each year we waited with apprehension for the heavy December rains.
Many times the creek flooded, transformed
from a flower-- choked summer trickle to a rampaging, muddy torrent, and
many times we scraped up the mud and dried damaged belongings.
Though all of the Tam Valley marsh and
half of the marsh in Tennessee Valley had been filled, I continued to visit
what remained. Most of the Tam Valley hillsides I used to frequent had
been built upon, so that by the time I was a student at Tam High my outdoor
explorations were confined primarily to the still--wild regions along Tennessee
Valley Road. Friends and I frequently studied and collected there for our
biology assignments, and my family went for picnics by a favorite old oak
at the crest of the road.
While I was away at college, I saw little
of the two valleys, but each time I returned I found that I had lost another
part of my heritage. The bottom corner of the Tennessee Valley marsh was
filled for houses, and the school filled most of what remained for an athletic
field. The great entrance gate for Marincello was built opposite our favorite
oak, and the soil from exposed road-cuts was washed by winter rains into
the choked remnant of marsh at the bottom of the valley. When I returned
after several years to Devil's Kitchen, it was filled with houses. The
wild azaleas, giant horsetails, and fort--like bays were gone.
The rest of the story is recent history,
and most of you will remember it. The residents of Tam Valley -- those
naive, innocent people like my parents who were dumb enough to buy a house
along a creek on a sunny, spring day without asking any questions, those
who bought homes in Kay Park and Crest Marin with no knowledge of floods
or no economic ability to buy anywhere else, and those who built on the
hillsides upstream with no understanding of run-off from exposed cuts,
rooftops, and driveways -- all these people together had to float a bond
issue for flood control. When I returned home from a trip one summer, our
back yard -- where for years we had nurtured flowers and vegetables and
fruit trees, and had relaxed beneath the shade of a mighty pine -- all
of it was gone. Where the creek of my childhood explorations and adventures
had been, there stood a great concrete channel lined with a chain link
fence and "keep out" signs. All around the neighborhood homes had been
sold, torn down, and replaced by huge apartments filled with commuters
who had no idea at all what they and their children were missing and
could never again have as theirs in Tam Valley.
Finally, defeated, my parents moved away
from Marin County, and so, for a time, did I. Now I am back again, and
every time I have to drive Shoreline Highway, past the apartments, the
tracts, the concrete ditch, and past my old home occupied by renter after
temporary renter, where, all the garden plants we tended with loving care
have been torn away, past all the children on their way to Tam Valley School
or Tam High who have so little of what I had, and who probably don't even
know why their lives are partially empty, I get a tough lump in the pit
of my stomach which takes a long time to go away.
What, you ask, does all this have to do
with a catwalk? Well, that is another little story, which is such recent
history you probably haven't even heard about it, but please bear with
me while I tell you.
There is a lady named Janet Walker, a Tam
Valley School mother, who is also a member of the Volunteer Council of
Audubon Canyon Ranch where my wife, Maggie, and I serve as Resident Biologists.
During her training as a docent and her work with children at the Ranch,
she became intrigued by the educational potential of our marshes, which
we have made more usable for study by the construction of catwalks. She
decided to arouse support for a catwalk and study area in the Tam Valley
School marsh, and came to us for advice.
Thank goodness there are visionaries left
in our midst! I didn't have the heart to tell her what a magnificent marsh
that used to be. I couldn't bring myself to express my anger that a school
-- a SCHOOL, mind you -- had filled the marsh in, had destroyed what could
have been, what should have been, the cornerstone for an entire educational
experience, then and forever. I kept silent my anger that, even after the
school was thus built upon its own best resources, no appreciable efforts
were made to utilize what was left, nor to use as a place of outdoor study
the magnificent rocky knoll and gnarled old oaks which stand just outside
the high, chain link fence of the asphalt play area. An athletic field
was built instead.
I didn't tell her about the soapstone incident.
Wouldn't the kids at the school be surprised to know that just back of
that huge craggy rock, on the cut made for the building of the school,
there is a great deposit of soapstone, and that when I was a student there
dozens of us spent every free moment excavating the precious stones, sanding
them and shaping them on the asphalt school yard and polishing them on
the wooden sides of the sandboxes? They would probably not be surprised
to learn, however, that instead of catching on to the merits of this splendid
resource and developing a whole soapstone craft project in the school from
which everyone could have benefitted, the teachers sent us to the Principal's
office for messing up the school grounds.
Nor did I remind Mrs. Walker that the silt
from Marincello had nearly filled in what remains of the marsh, that great
thickets of willows have invaded the resulting higher ground, taking water
from the marsh until none is left for polliwog, newts, and dragonfly nymphs,
that the new Marin View development just completed last year -- built on
steep hills behind the school where no sensible county government would
have allowed disturbance of the fragile soil -- caused so much sliding
and siltation during last winter's heavy rains that the marsh filled even
I said instead to Janet Walker that she
was on to a great idea, and that we would ask the young man who built our
catwalks to help with the design of hers if she would only raise the support
and pick her spot. These things she did.
It was a new and rather startling idea
for the school, but the Principal agreed to the idea. Armed with $100 from
the PTA and some hard-working husbands, Mrs. Walker and other interested
parents succeeded in building a tiny 20 foot long catwalk into a corner
of the marsh surrounded by impenetrable willows where no water will stand
between late spring and the mid--winter rains.
And then along came the Department of Public
Works surveying to improve Tennessee Valley Road. This in itself is a subject
with a lengthy history. Many plans for the development of Tennessee Valley
have been raised and defeated. There was once talk of rerouting Highway
1 along this road and then over the headlands to Muir Beach, bypassing
Tarn Valley entirely. Various Subdivision plans, and finally Marincello
itself, were dismantled. Except for the school, the houses in the lower
marsh, the Marincello roads, and the abominable Marin View, the valley
has somehow escaped major development.
But now the GGNRA has arrived. It is an
inescapable reality, and just as inescapable may be the idea that Tennessee
Valley is the most logical Recreation Area roadhead in this part of Marin.
roadhead would mean more people, and more people would mean more cars and
bicycles. Increased traffic would demand a wider road, and the only place
to put the extra width seems to be in what remains of the flood plain of
Whether a roadhead is behind the plan or
not, the County seems to desire a wider Tennessee Valley Road, to "bring
it up to standard." During preliminary investigations for the project,
someone spotted the catwalk and determined that it was built without a
permit. Fears were aroused that during high water the structure would float
up and out, causing blockage to the flow of water downstream where the
floodplain narrows again into a dredged channel.
Novato Creek Naturalist Don Engler was
called in as a consultant by the District to evaluate the situation, and
together they requested that Mrs. Walker reconstruct the walk so that it
could be removed from about mid--November through April. That would leave
one and a half months at the end of the school year for the kids to use
the structure when there is water and any appreciable biological activity
in the marsh.
That little walkway at the edge of a dying
marsh means a great deal to Mrs. Walker and her fellow parents, and it
could mean more to the kids of Tam Valley School than we will ever know.
I stopped by for a look at the place at 6:30 one recent foggy morning.
It was the first time I had been back to my fifth grade school in many
years. The place looked small and choked. Houses surround the school on
three sides, and enormous PG&E high--voltage towers stand at either
end, the lines passing directly over the athletic field. Where my favorite
pond at the edge of the marsh once stood, filled with the croaking of treefrogs
and the hum of bees at the pennyroyal, now stand the entrance gates for
Marin View. The catwalk seemed small and lonely, surrounded by the strangling
willows and a piece of open marsh the size of a modest back yard.
I had a vision of what the two valleys
might have become. A controlled number of houses built back from the creeks
and marshes but leaving the hills for the most part wild. A school built
at the edge of its own priceless outdoor study area. A viable community
small enough in size so that people could become acquainted, work together,
and share in the exploration of the land. Children with space to run in
and wild things to learn from.
And then I thought about Barbara Schrock,
write--in candidate for the Tam Valley Community Service District, who
wants more recreation facilities. When I was a kid in the valley, we didn't
need "facilities." We had the hills to hike in and the fields to play football
in. Recreation was spontaneous, creative, inventive.
I remembered again Coyote Creek made sterile,
and Corte Madera Creek and Tamalpais Creek, and the creeks of Terra Linda,
Lucas Valley, and Novato following suit. I thought of all the marshes long
since filled, like the ones where Redwood High School and Mill Valley's
new Middle School now stand, and I wondered what the students in these
schools know about the heritage that could have been theirs.
Not much, I guess. They study biology in
text books while the great marshes rot under them, beneath six feet of
I thought again about my Tam Valley childhood,
and I realized that almost everything I know about the natural world
I learned during those years. Most of what I studied in college text books
I have forgotten, but childhood experiences have stayed with me. Those
years cannot be repeated; every wild place of significance which I knew
as a kid is gone, transformed, sanitized, "brought up to standard." I realized,
standing in that desolate asphalt and weed covered school yard, that when
I wrote LIVING WATER, a story about the Sierras and the mighty watershed
of the Sacramento River, I was really writing a eulogy for the little watersheds
of my childhood creeks, and that THIS LIVING EARTH, which traces the learning
process my wife and I experienced in the San Geronimo Valley and West Marin,
is just as much an epitaph for the house--covered Tam Valley grasslands.
Tam Valley School is, as an educational
setting, still one step ahead of a school in the heart of San Francisco,
but just barely. I can tell Janet Walker to fight for her catwalk, and
she can take what heart in that she may. I can tell the Department of Public
Works to keep their hands off the catwalk because it won't have a single
ounce of impact upon their flow of water, and I can hope that they will
listen. But inside, I cry for what this land once was. In my mind, I see
all those children with no place to go. Sure, they will have all of GGNRA,
Audubon Canyon Ranch, Taylor Park, Point Reyes and Tomales Bay. They can
visit those places, and they will have more than many people in the world
have. But visiting a wild place is no substitute for living in the midst
It is time to make the Countywide Plan
more than ink and paper. Make it real! We must stop uncontrolled growth.
If there are no more houses to live in, sooner or later we will have fewer
children because, I am sad to say, man tends to react out of necessity
more often than he does upon the powers of reason. If no growth threatens
present occupations, then we will have to retrain ourselves in new ones
which better fit community needs.
If we want to build, then let us rebuild.
We could have our creeks again, and our marshes. The same bulldozers which
filled them - could dig them out again. If we experienced no further growth,
homes could be relocated and at least some of the integrity of our watersheds
could be restored. It is possible to rebuild our communities so that every
member, young and old alike, has a wild place close to home where the real
roots of our species can be felt and experienced, and we would come to
know each other and to work together better than we ever have before.
Kids would not stand idle in front of the
local drive-in popping pills because they would feel a part of the community
purpose. They wouldn't have time to feel lost and alienated because there
would be work to do, hard work and plenty of it rebuilding the place called
It is possible, but not likely. We have
come that far as a species only in our dream.
