This June, the San Diego Chapter will be “Slip Slidin’ Away!” Robert J. Reese, PLS, will make a presentation about establishing boundary lines in an area subject to subsidence – not disastrous, immediate earthquake-type subsidence, but a slow shift of the earth.

The account involves LA County’s actions and causality, a city’s attempt to stop Mother Nature, and various surveyors’ attempts at retracement in a shifting environment.

Attendees will be offered an opportunity to comment on the methods and reasons of a survey that has been questioned by the LA County counsel, other surveyors, and some landowners.
