Land Survey Costs in New London County, CT
New London County occupies the southeastern corner of Connecticut, bounded by Rhode Island to the east, Long Island Sound to the south, and the Thames and Quinebaug river valleys to the north. It is one of Connecticut’s most geographically varied counties, mixing coastal resort communities, inland forested terrain, tribal lands, and the industrial port complex at Groton. In 2026, property owners in New London County can expect to pay between $550 and $1,000 for a standard residential boundary survey, with coastal and waterfront properties typically landing at the higher end.
Geographic Factors That Affect Survey Costs
New London County’s terrain ranges from Long Island Sound barrier beaches and rocky coastal bluffs in Stonington and Old Lyme to the wooded inland hills of Montville and Ledyard. Coastal surveys often require flood zone research and mean high water determinations, adding time. Inland parcels near the Uncas Leap area of the Yantic River or along the forested ridgelines of the eastern uplands may have limited existing monumentation, requiring more fieldwork to recover or establish lot corners.

Community Highlights
New London
The City of New London sits at the mouth of the Thames River where it meets Long Island Sound. It is one of Connecticut’s older port cities, with a downtown grid and residential neighborhoods that carry layered property histories. Surveys in the city often involve older deed descriptions and prior plat records. The waterfront district and harbor-adjacent neighborhoods have flood zone exposure that adds elevation certificate work to the local surveying mix.
Norwich
Norwich sits at the confluence of the Shetucket and Yantic rivers, which merge to form the Thames. The city’s residential neighborhoods span terrain from river-bottom floodplain to upland streets, and the surrounding Thames River valley has active residential and commercial real estate. Survey work in Norwich ranges from straightforward suburban lots to more complex river-adjacent parcels that may require flood zone assessment.
Groton
Groton is home to Naval Submarine Base New London, one of the nation’s premier submarine commands, as well as a substantial civilian residential and commercial base. Properties adjacent to the naval installation create unique surveying requirements: federal boundary constraints mean surveyors must work from established reference points and cannot access base perimeters to set or recover monuments. For civilian homeowners near the base, this can affect fieldwork logistics and cost. Groton also has waterfront residential development along the Thames River and Fisher’s Island Sound that generates elevation certificate demand.
Stonington
Stonington Borough is a tightly packed historic village on a peninsula extending into Fishers Island Sound. Its narrow streets, small lots, and proximity to the water create both historic survey complexity and coastal flood zone exposure. Pawcatuck, the western section of Stonington, has more typical suburban character. Waterfront properties throughout the town consistently require elevation certificates for flood insurance purposes.
Old Lyme and East Lyme
Old Lyme and East Lyme anchor the county’s western coastline along the Connecticut River mouth and Long Island Sound. Old Lyme’s Lieutenant River and Connecticut River shorefront communities are flood-prone, and elevation certificates are common for properties in these areas. East Lyme’s Niantic Bay and Rocky Neck State Park vicinity have similar coastal flood dynamics. Both towns attract seasonal and year-round residents drawn to the shoreline, keeping local survey demand active.
Ledyard and Montville
Ledyard and Montville are largely rural and suburban inland towns with significant tribal land holdings from the Mashantucket Pequot and Mohegan tribes respectively. Survey work here tends to involve larger parcels, more fieldwork time due to wooded terrain, and occasional questions about reservation boundaries and their adjacency to private land. Costs for rural lots in these towns are typically at the lower end of the county range.
Naval Presence and Adjacent Residential Surveys
The Naval Submarine Base in Groton is the largest employer in the county and draws military personnel and civilian workers who purchase homes throughout the Thames River valley. That population creates consistent residential real estate activity, which in turn drives steady demand for boundary surveys and title surveys in Groton, Ledyard, and the Gales Ferry area. Surveyors familiar with the military installation perimeter and its implications for adjacent property work are particularly well-suited for this corridor.
