Full-Service Land Surveying for Every Project
From small residential lots to complex development sites, we offer a wide range of surveying services to meet the needs of homeowners, contractors, developers, and municipalities.
Certified Survey Maps (CSMs)
Required for dividing land or combining parcels, Certified Survey Maps provide clear documentation and legal definitions of property lines. We work closely with clients and municipalities to ensure maps meet local requirements and help streamline the approval process.
Plat of Surveys
If you're purchasing or selling a property, a Plat of Survey shows the existing boundaries, structures, and improvements — giving you and your title company the documentation needed for a smooth closing.
ALTA/NSPS Land Title Surveys
For commercial real estate transactions, we offer ALTA surveys that meet the standards of the American Land Title Association and the National Society of Professional Surveyors. These detailed surveys are often required by lenders and investors and include boundary, title, and encumbrance information.
Site Plans and Subdivisions
Whether you’re building a new home or designing a multi-lot development, we provide site planning and subdivision surveys that help lay the groundwork for engineering, zoning, and permitting processes.
Easements and Legal Descriptions
Need to define or record an access easement or utility corridor? We create precise easement surveys and legal descriptions for filing with local governments, ensuring your documents are accurate and enforceable.
Topographic Surveys and GPS Grade Control Models
Our team delivers topographic mapping and GPS models for contractors, engineers, and developers who need accurate elevation data and site modeling. These are essential for grading, drainage, and large-scale construction planning.
Boundary and Fence Line Surveys
Buying a new home? Planning to install a fence? Dealing with a neighbor dispute? A boundary survey gives you peace of mind and legal clarity by marking property lines accurately and permanently.
Airport Lease Surveys
We offer specialized airport lease surveys for aviation clients needing certified measurements for hangar placement, lease boundaries, or FAA documentation.
