FFA
officerin 1950 and anAmerican
Farmer, bought the Smith farmsome
30 years ago."When
I firstbought,"herecalls, "Iwas
in the dairy business. I bought this 17 acreswiththehouse,dairybarnandirri-
gated land for$27,000. I eventually got tired of milking cows, bought the pas- tureland and started in beef.
Now
land around here is going for asmuch
as $5 per square foot." Considering 43,560 square feetperacre, that's $217,800 an acre forsuburban and commercial land.MostoftheSmithfarmacreageisbetter suited for
cows
insteadof houses.None-theless,arecent appraisalsetthevalueof theSmithranchat$350,000.
With suchanappreciationrateonthe land, the effect ofurban sprawlon land value
may seem
desirable. Butunless a farmer begins liquidating land, the ap- preciated land value brings expense in- steadofincome."Taxes20yearsagoontheproperty,"
remembersLouie, "were $375 peryear.
Now
it's up to $2,500. It'll keep going up, too,andnothingwe
candowillstopit.If
we
take thecattle off,taxes willbe evenhigher. Icanjustseeuspayingcity taxoncattle."IntheU.S.tax structure,taxes usually rise sharply
when
land values increase.Some
stateshavetakenlegislativeaction toeasetheburdenfeltbythelandowning farmer. InNorth Carolina,theFarmland Taxation Actwas
passed in 1973 after average land value peracre doubled in less than ten years.Under
this legisla- tion, qualifying farmlandmay
be as- sessedandtaxed on thebasis ofcurrent use value rather than market value of potential development.Many
states are moving towarda tax breakforfarmland butmany
farmersremainfaced withris- ing taxes.The
Smithsaren'taloneintheir plight.Accordingtoareportissuedbythe
Urban Land
Institute (ULI), a Washington- based researchandeducational organiza- tion, the fastest growing areas in the UnitedStates since 1970have beensmall cities, towns and open countrycom-

In the distance, the eastern hillside is coveredwith the clutterof
new
buildings, reasonenough
forKevintoponder
hisfamily'sfarming future."When
thecitystartedgrowing,"says Kevin, "more andmore
trespasserscame
to the farm. At night, drivers of all- terraintrucksandmotorcycles
would
cut our fences and drive over the pasture.They
've evenjerked outwooden
fence- postsandbuiltbonfires. I'vefoundbro- ken posts and wire where people have taken close-range target practice with their rifles.And
the law can't catch them."Although the intruders' visits have slacked off
—
Louie says it's because of the fuel shortage—
the Smiths have re-solved to leave the farm. They're cur- rently searching for another place
—
a
place
where
their land will be un- molested, aplace where land expansion won'tmean
financial burden from city taxes."We've
got to find an irrigated farmfurtherout sowe

showing

of land farmed in the United States.The
U.S.Departmentof Agriculture estimates 2.7 million acres of cropland are lost each year
—

shares Kevin.Butchered cattle in the field, constant traffic, trespasserspullingguns on land-
owners
trying to protect their property— problems
occurringmore
regularly as the citygrows.
"It all stems from disrespect," says Louie, a tone of aggravation in his words. "People
come

They
might have three kids, buy ahorse andacouple of dogs.Before long, the kids are on yourprop- erty, the horse has eaten

somewhat
by Louie's hopefulthought: "Eventuallythe sprawl shouldstop.It'sgottoend somewhere."39
