Couldn't find this one. I know in the last several years they had redone much of Main Street - and in the process - this one might be buried. I'm starting to think any mark containing the words "Standard Erie County Survey Disk" is lost to the ages...but it's only a guess at this point based on my track record. Haha.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in January 1999.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
