HomeMy WebLinkAboutSurvey 20992PURPOSE:
THE PURPOSE OF THIS SURVEY IS TO REPLACE ONE MONUMENT THAT WAS DESTROYED DURING LA PINE ADA RAMP IMPROVEMENT PROJECT PURSUANT TO
ORS 209.150(1).
RESEARCH:
WE RESEARCHED ALL OF THE SURVEYS OF RECORD WITHIN THE LIMITS OF THIS PROJECT TO DETERMINE WHERE RECORD MONUMENTS FELL. A SEARCH WAS
CONDUCTED FOR THESE MONUMENTS AND WE FOUND ONE MONUMENT (30000) THAT WOULD BE DESTROYED. WE TIED, REFERENCED AND RESET THE
MONUMENT AFTER RAMP CONSTRUCTION WAS COMPLETED.
REFERENCING PROCEDURES:
THE FOUND MONUMENT WAS INITIALLY TIED BY MAKING AT LEAST THREE FIVE MINUTE GPS REAL TIME KINEMATIC (RTK) OBSERVATIONS. IF THE MEAN OF THE
THREE RTK OBSERVATIONS RESULTED IN A HORIZONTAL POSITION DIFFERENCE EXCEEDING 0.05', ADDITIONAL OBSERVATIONS WERE MADE UNTIL THE
PROJECT HORIZONTAL TOLERANCE OF LESS THAN 0.09 WAS MET.
REMONUMENTING PROCEDURES:
AFTER THE RAMP CONSTRUCTION, A NEW MONUMENT WAS SET BACK IN THE ORIGINAL POSITION BY TOTAL STATION RESECTION, AND CHECKED AGAINST
MEASURED DISTANCES FROM THE NEARBY PROPERTY MONUMENTS.
QUALITY CHECKS:
A CHECK SHOT WAS TAKEN ON THE NEW MONUMENT BY MAKING ONE RTK OBSERVATION ON THE NEW MONUMENT OF ONE MINUTE OR LESS. THE RESULT OF
THE CHECK SHOT WAS WITHIN EXPECTED TOLERANCES. THE QUALITY CHECK OBSERVATION IS TO ENSURE THAT NO ERRORS WERE MADE DURING THE
RESETTING PROCESS.
PUBLISHED COORDINATES:
THE COORDINATES IN THE MONUMENT TABLE ARE THE WEIGHTED AVERAGE FROM THE INITIAL OBSERVATIONS (THREE OBSERVATIONS OF FIVE MINUTES
EACH).
MEASURED AND RECORD DATA -
FOR THE MONUMENTS WHICH WERE ORIGINALLY SET PER CS20318, THIS MAP SHOWS OUR MEASURED VALUES BETWEEN FOUND MONUMENTS COMPARED TO
THE RECORD DATA
DISCLAIMER:
NO CERTIFICATION IS BEING MADE AS TO THE POSITION OF FOUND MONUMENTS RELATIVE TO ANY RECORD PROPERTY LINE OR SECTION LINE OTHER THAN
THE LOCATION AT WHICH IT WAS FOUND AND TIED BY DESCHUTES COUNTY IN JUNE OF 2022.
