Compute the elevation of TP1 after correcting for “curvature and refraction” given:

“BM A” elevation = 595.00’ (NAVD 88)

BS (plus sight) rod reading on “BM A” = 7.00’ at a horizontal distance of 1,900'

FS (minus sight) rod reading on “TP1” = 1.00’ at a horizontal distance of 1,950'

Please put the final answer in feet.
