Place stake (A) at the corner of the planting block and on the ref-
erence line. Fasten the end of a 200-foot-long tape measure and the
120-foot mark of the tape to stake (A), forming a loop. Place stake (B) on
the reference line and 30 feet from (A). Bring the tape to the outside of
stake (B) and walk in the direction of (C) holding onto the 80-foot mark on
the tape. When both legs of the tape from stakes (A) and (B) are tight, you
have reached (C) and formed a 90-degree angle. Place stake (C) on your
new reference line.
Place one stake (A) on the reference line where you want the corner and
slip the end grommet of the measuring tape over the metal stake (see
figure
tape in place so that it cannot slip. Stake (A) forms the first corner of the tri-
angle. Measure 30 feet along the reference line that you laid out earlier and
place a second stake (B) at this point. Run the measuring tape on the out-
side of the stake. This is the second corner of the triangle. Holding onto the
80-foot mark on the measuring tape, walk at approximately right angles to
your reference line from stake (A), stretching the tape until both segments
from stakes (A) and (B) are tight. Place a stake at (C) to mark the line. You
have now formed a triangle at a right angle to your reference line. The stakes
serve as the corners and the measuring tape shows the sides of the triangle.
For greater accuracy, use a 300-foot-long tape and make the sides of the
triangle 60, 80, and 100 feet long. With a 300-foot tape, place the end grom-
met and the 240-foot mark on the measuring tape at stake (A). Place stake
(B) 60 feet along the reference line and run the measuring tape on the out-
side of the stake. Holding onto the 160-foot mark on the measuring tape,
walk in the general direction of (C), as described above. When both segments
of the tape from stakes (A) and (B) are tight, place stake (C).
Extend your right angle line for the width of the block by stretching your
measuring tape or twine from the corner stake (A) and just touching the
right angle corner stake (C). Repeat the procedure until all of the planting
blocks and roads are marked.
