Once again, measurement to the street, using a 3degree slope

Elevation 429.7 = TSBD at street
Plat élévation for shot at 418.35
Difference = 11.35ft
TSBD window sill= 60.7ft
60.7ft + 11.35ft = 72.05ft
72.05squared x 257.18squared =267.08hypotenuse = plat entries for elevation 418.35

The 3 degree slope = 5.238% grade = 1ft vertical/19.09ft horizontal ratio
Elevation change = 11.35ft
11.35 x 19.09 = 216.67ft

TSBD = Station# 2+50
2+50 + 216.67ft =Station# 4+66.67 = Tom Purvis' info obtained via Robert West.
