Riverine Adventure! A Surveyor's Guide to River Boundaries & Overview of Laws Regarding the Navigation of Texas Streams

Saturday, December 3, 2016 | Houston, Texas

Presented by Michael Hoover, RPLS, LSLS, CFM and David Klotz, RPLS, LSLS
(6 hours of CEUs)

Surveying boundaries along rivers and streams in the State of Texas can present the surveyor numerous problems. Is it navigable? Should a gradient boundary be performed; and, if so, should the RPLS determine such a boundary? What rights does the public have within, over and across any such stream?  How does the surveyor handle a boundary line along a tidally influenced stream? This course will answer all of those questions and more, covering river characteristic fundamentals and fluvial morphology; the history, development, and basic application of the gradient boundary; navigation and the navigation right; relinquishment acts; and stream uses and obstructions. Case law review and real life case studies will be prominently used to illustrate the presented concepts and encourage discussion. This will be an interactive seminar with plenty of visuals. At the end of this riverine adventure each attendee should be able to stamp his/her return ticket from the “River of No Return”!

  • Survey, grant, and deed retracement
  • Records search
  • Preparation of working sketches
  • Previous surveyors and their methods
  • History of the area at the time of the orginal survey
  • Identify GLO symbols
  • Principle ruling of selected court cases

Participants who attend will:

  • Participate in the determination of the gradient boundary of the Frio River.
  • Capitalize on techniques for determining corner search positions learned over years of experience.
  • Appropriately apply the field evidence to final original survey construction to legally establish missing
    or obliterated corners.
  • Review landmark court cases that were the basis for the current dignity of calls in regard to retracing original survey corners.
