Simple and Timeless Field Monitoring Tools

Complicated CR documents often contain very specific language regarding areas where a landowner may and may not exercise certain reserved rights.  For example, a building envelope typically allows an owner to maintain existing structures and build new ones as negotiated in the CR document.  Areas such as these have, ideally, been physically monumented by a professional surveyor and labeled, with metes and bounds (distances and bearings) on the property's survey or plan of land.  For example, a CR might state that, on a certain part of the property, no reserved-right construction activity may occur within a certain distance of a sensitive resource area, such as a wetland. 

Sometimes Trustees' monitoring staff need to check these distances in the field, or determine exactly where a property or building envelope boundary lies.  Below we highlight two simple but indispensable tools for such determinations. 
In the first picture below, staff employ a good old-fashioned tool - a simple tape measure - to determine the distance from a restricted property boundary to new construction on the same landowner's unrestricted parcel.  Here, the measurement point was a professional surveyor's monument on the boundary line of the restricted property, allowing us to be sure that we were measuring from a very exact reference point out to the construction area.

Other times, it is necessary to determine exactly where a property line lies.  In New England, we often, but certainly not always, have the benefit of historic stone wall boundaries to help us.  Modern technology supplies us with GPS units, which are nice approximators, but ours have a margin of error ranging from 5 to 15 feet, depending on satellite reception.  However, with the help of a survey and the timeless and indispensable tool pictured below, we are able to determine that boundary within a much more precise margin of error - a margin which only a professional surveyor could best.  You may have already guessed what tool that is, and here it is -
