s% Septe.mber 10, 1979 29 6-5 710 Lloyd Schnelle City Administrator City of Ramsey 15153 Nowthen Blvd. Anoka, Mn 55303 Dear Mr. Schnelle: The Minnesota Department of Transpor. tation is currently perfor.ming a 2nd-order horizontal control survey along the ~oute of State Trunk Highway 47 from the junction of. U.S. Highway 10 in Anoka to the Town of St. Francis. The survey consists of placing permanent concrete monuments 12 inches in diameter and 4% feet in depth into the ground at approximately 2 mile intervals. From these monuments, precise angles and distances are measured to determine their horizontal position with reference to latitude and longitude and to the Minnesota State Plane Coordinate System. The purpose of this type of sUrvey is to provide permanent horizontal control monuments at 2-3 mile intervals that are accessible to State, County, City, and private surveyors so that all surveys are related to .one.. datum. This is especially important when e.stablishing land boundaries. The Department of Transpor. tation is presently doin'g surveys along Trunk Highway 47 to determine and monument the right of way, and to provide control, for proposed bridge replacements. Three of the proposed monument locations are on property belonging to the City of Ramsey. One is located southeast of the new City Hall, the secOnd one is located at the Trott Brook Cemetery, and the third is at the old City Hall. A portable survey tower will be used to make the measurements from the monument at the cemetery. The survey tower is necessary in order to see over the t~ees to .our monuments located along the highway. The tower consists of a lattice structure resembling a farm windmill that is erected to a height of 64 feet. The tower takes one day to .er. ect and one day to make the required measurements and then take it down. An Equal Opportunity Employer
