The simple answer is, when time and weather permits or if we have been advised of a special situation or work area conflict that we need to know about. Usually, it’s pretty simple. If you measure you own property and keep in mind the guidelines above of a 7-8 foot work perimeter around the tent it’s usually fine. Remember to look up for tree branches and wires and mention any underground septic field or irrigation systems that we should know about since the utility companies will not mark those two things because they are your responsibility.
