Not sure whether you need a boundary survey, topographic survey, ALTA/NSPS survey, construction staking, parcel map, lot line adjustment, or specialty survey? Terwilliger Land Survey Engineers helps property owners, developers, contractors, architects, engineers, title professionals, and real estate teams identify the right survey for the project before delays begin.
You may need a boundary survey, ALTA/NSPS land title survey, or other due diligence survey depending on the property type, lender, title requirements, and transaction timeline.
You may need a topographic survey, boundary survey, or both to support design, permitting, grading, drainage, and site planning.
A boundary survey can help identify property corners, lines, easements, and possible encroachments.
Construction staking translates approved plans into the field so improvements can be built in the correct location.
An ALTA/NSPS land title survey may be required for title review, financing, lender requirements, and due diligence.
The right survey depends on your project goal. A boundary survey helps identify property lines and easements. A topographic survey maps existing site conditions and elevations. An ALTA/NSPS survey supports commercial real estate, title, and lender due diligence. Construction staking helps builders transfer plans into the field. If you are not sure, send us the property address, APN, project type, and timeline.
Please provide the property address, APN if available, type of survey requested, project purpose, timeline, and any deeds, title reports, prior surveys, architectural plans, civil plans, or legal descriptions you have.
Many projects need one or the other, while some need both. A boundary survey focuses on property lines, easements, and corners. A topographic survey focuses on existing site features, elevations, and contours. Projects involving new construction, additions, grading, or design often benefit from both.
It is best to request a survey early, especially when survey information may affect a property purchase, design process, permit application, construction schedule, or title issue.
Yes. Terwilliger provides ALTA/NSPS land title surveys and related survey services for commercial real estate transactions, financing, title review, and development planning.
