Homeowners and mortgage lenders alike often require boundary surveys to protect their investment and avoid legal disputes. That's why it’s important that survey work is completed by a licensed land surveyor. If you’re a property owner selling, buying, subdividing, or refinancing, McMillen Engineering, Inc. can conduct your boundary survey for you.


We also work with banks to ensure that setback and zoning requirements are met for residential or commercial purposes. Land modification projects like adding a fence or a building should also begin with a boundary survey to locate corners and property boundary lines.

Topographic Surveys


McMillen Engineering, Inc. also completes topographic land surveys to identify natural and man-made land attributes and elevations. The results from these topographic surveys are used by our civil engineers to accurately prepare design work. If you’re already working with an engineering firm but require a topographic survey, we could conduct the survey and provide those results to you.


Our surveyors can conduct a floodplain survey to determine whether your property is located within a specified flood zone. These surveys are essential to assess the risk and provide accurate data to insurance companies and stakeholders. A PA Flood Elevation Certificate may be provided to you (if applicable) to assist you with defining your flood insurance policy and cost.
