It is a pretty gradual curve. For cross checking purposes using Jim's
suggestion the straight line length (the chord distance for that arc)
calculates to 254.88 feet using two place round off. Ck my math haven't
calculated one of these in years.
/r/ is the radius of the circle
/c/ is the angle subtended <http://www.mathopenref.com/subtend.html>
the center by the chord (9.67 deg by my calculation --- 256.09 divided
by 9532.52 times 360 )
/sin/ is the sine function (c/2 = 4.835 and sine of which is ~.084)
2 x 1517.15 x .084 = 254.88
Must be a pretty recent survey. This calculates to a difference of two
feet difference at the center of the arc. I can't imagine old timers
worrying about 2 feet one way or the other as far as how it affects the
right of way of the road. When curbs and sidewalks; utility placement
are concerned in today's world, I suppose it matters.

I don't believe that Deed Mapper has a way for you to enter an arc. Not only that
but from the information you gave you don't know which side of the arc the property is
on. Being inside would add area while being outside would delete area.
However, I'll bet a straight line won't miss the correct area by much. Your arc
is part of a circle with a circumference of over 9532 feet. Your arc is less than 3% of
the circumference. I suggest you try entering all of the other values and use the
"back to the beginning" option on the last entry.
