STATION IS LOCATED ON TOP OF THE HOSE DRYING TOWER IN THE REAR OF THE CITY HALL BUILDING IN SOMERS POINT, N.J. AT THE SW CORNER OF SHORE ROAD AND NEW JERSEY AVENUE. THE STATION MARK IS 52.5 FEET ABOVE THE LEVEL OF THE CONCRETE FLOOR IN THE TOWER. MONUMENT IS ATTACHED TO THE ROOF WITH SPIKES.
STATION MARK IS STANDARD BRONZE DISK SET IN CONCRETE AS DESCRIBED IN NOTE 1A. REFERENCE MARKS ARE STANDARD BRONZE DISKS SET IN CONCRETE AS DESCRIBED IN NOTE 11A EXCEPT CONCRETE MONUMENTS WERE FASTENED TO THE UPPER END OF 2 X 4 PILES DRIVEN INTO THE GROUND.
REFERENCE MARK NO.1 IS LOCATED 1.75 FEET FROM WIRE FENCE TO THE S, 15.15 FEET FROM 2-INCH PIPE POST AT EASTERN END OF FENCE LINE, 18.60 FEET FROM NEAR EDGE OF SIDEWALK, 25.95 FEET FROM COPING ON NEAR EDGE OF SHORE ROAD AND 55.10 FEET FROM FAR SIDE OF SHORE ROAD, 100.5 FEET FROM SE CORNER OF CITY HALL BUILDING.
REFERENCE MARK NO. 2 IS 2.1 FEET FROM WIRE FENCE, 36.1 FEET FROM 2-INCH PIPE POST AT WESTERN END OF FENCE, 64.0 FEET FROM CENTER LINE OF GRAVEL ROAD TO WESTWARD, 101.0 FEET FROM SW CORNER OF CITY HALL BUILDING. ALL DISKS ARE STAMPED SOM 1935. REFERENCE MARKS STAMPED 1 AND 2 RESPECTIVELY.

|RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1950 (HFG)
STATION AND REFERENCE MARKS WERE RECOVERED IN GOOD CONDITION. THE DISTANCE FROM REFERENCE MARK 1 TO REFERENCE MARK 2 WAS MEASURED WITH A STEEL TAPE AND FOUND TO BE CORRECT. THE PUBLISHED DESCRIPTION IS ADEQUATE AND CORRECT.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1999.
- The orthometric height was scaled from a topographic map.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
