HILL BOULEVARD (PREVIOUSLY KNOWN AS CENTRAL BOULEVARD), SHOWN ON THAT CERTAIN MAP ENTITLED "E. 14TH ST. HOME SITES", RECORDED IN BOOK 18, AT PAGE 56, ALAMEDA COUNTY RECORDS. THE MONUMENTS FOUND WERE NOT IN THE LOCATIONS
SPECIFIED ON THE MAP, BUT WERE AT THE POT AND PRC LOCATIONS IN FRONT OF LOTS 16/58 AND 22/65 RESPECTIVELY. THE BEARING BETWEEN THESE 2 POINTS IS CALCULATED AS N38°16'47"W.
BASIS OF ELEVATION:
THE PROJECT BENCHMARK IS NGS PT HT0201, PID P 1197
FOUND 1.9 MILES SOUTHEAST ALONG THE SOUTHERN PACIFIC RAILROAD FROM THE STATION AT HAYWARD, 0.3 MILES SOUTHEAST OF THE CROSSING OF HARDER AVENUE, 5 POLES NORTHWEST OF MILE POLE 22, OPPOSITE A WOODEN RAILROAD BRIDGE OVER WARD CREEK, IN THE TOP AND 1.0 FEET NORTHWEST OF THE SOUTHEAST END OF THE NORTHEAST CONCRETE HEAD WALL, 49.0 FEET SOUTHEAST OF THE SOUTHWEST RAIL, AND 39 FEET NORTHEAST OF THE CENTERLINE OF HUNTWOOD AVENUE.
