Jon personally visits a client's home and talks with each client to learn what end result the client is seeking with their landscape project. He explains what you need to know in order to accomplish that goal within budget. Then he blocks time off in his schedule where he and his team are going to work on your project specifically.

Land Surveying questions, answered by experts

This is fairly rare, but sometimes the local government or a group like a historical society will label a tree as a landmark, or historical item. These designations almost always come with a small, on-site plaque for identification, but you should also be able to look up protected trees in your area on a city website or similar list. If the tree in question is a landmark, call your local government and ask how to proceed before making any plans.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

To prepare for a land survey, you must thoroughly check your land surveyor’s qualifications, reviews, and fees to align with your expectations. When it is time for the survey to be conducted, ensure that you have all your documents organized and available, know and mark your property lines, and inform your neighbors that the survey is happening.

Surveys completed by licensed surveyors can be recorded with a local surveying records office, and in most cases, they will be. Filing survey reports categorize them as legal documents, and they can be used whenever legal documentation of your property’s boundaries is needed. While you’re not required to file survey documents, it’s a good idea to do so. 

It is almost always necessary to hire a land surveyor near you to ensure your fence sits on the right side of the property line. Mistaking the shape of your property can lead to fines and costly changes if you have to move or adjust the privacy fence—not to mention some surly looks from your neighbor. We recommend jumpstarting your fence planning in the spring to ensure there is plenty of time to map out your plan before construction season.
