Contesting Flood Zones
Homeowners typically need an Elevation Certificate when a lender requires flood insurance or when applying for a Letter of Map Amendment (LOMA) to remove that requirement. We pull the effective FIRM panel and conduct flood-map research to confirm your actual zone and base flood elevation. If the map misclassifies your property, we prepare the official documentation to support your amendment.
Fieldwork and Documentation
We measure your structure's elevation and compare it against the effective FIRM panel. The current FEMA Elevation Certificate form requires specific documentation, including photographing the building front and back exactly as the form requires. We ensure these photos show the necessary foundation details without obstruction. Melrose sits in a cool climate with cold winters (climate zone 5A), so we often have to clear snow or work around winter weather to get the clear grade shots FEMA demands.

Pricing for LOMA Support Packages
We charge $500 to $1200 per Letter of Map Amendment support package. This includes the site visit, photographing the building front and back, flood-map research to confirm the zone and base flood elevation, and finalizing the required forms. The final price depends on the complexity of the property and the time required to verify the effective FIRM panel data.

Questions Melrose Customers Ask
The property address and, if you have them, a copy of your deed, any prior survey, and your title commitment. Access to walk the property helps, and if there's a specific reason for the survey — a fence, a sale, a building permit — telling us up front lets us scope it right the first time.
Price tracks the work, not the lot size alone. A clean platted lot with good corners is quick; a parcel with missing monuments, conflicting deeds, heavy tree cover, or a metes-and-bounds description takes far more research and field time. We quote after we see the deed and the record, so the number is real.
Usually yes, and often the permit requires it. Building to an assumed line is how encroachment problems start — a fence a foot over the line can cloud a future sale. A current boundary survey shows exactly where you can build and keeps the improvement on your own ground.
It's marking the site so the contractor builds in the right place — offset stakes for the foundation, grade stakes for elevations, and layout for utilities, all set from the engineered plans. It's done in stages as the job progresses, which is why it's usually quoted per visit rather than as one flat fee.
A boundary survey with improvements locates visible features and the easements shown in the record — utility lines, drainage, access, and any structures near the lines. A full ALTA goes further. If a recorded easement doesn't show on your deed, the title research is where it turns up, which is one reason the record work matters.
Land survey costs vary based on property type and complexity. A residential boundary survey on a platted lot typically ranges from $500 to $1,200, while surveys for acreage or unplatted parcels can cost $1,200 to $4,000. Commercial ALTA/NSPS surveys range from $2,000 to $8,000. Factors like terrain, property size, and required details (e.g., easements, encroachments) influence pricing.
Surveying property yourself is not recommended. Land surveying requires specialized equipment, knowledge of legal boundaries, and adherence to state regulations. Only licensed surveyors can produce legally binding surveys. Attempting DIY surveys may lead to inaccuracies, legal disputes, or issues with property transactions.
A Few More Questions
It's a form a licensed surveyor completes documenting your building's elevation relative to the base flood elevation. You'll need one to buy or reduce flood insurance in a mapped flood zone, or to support a Letter of Map Amendment if you believe your structure was mapped into a floodplain by mistake.
Yes. Where corners are missing we set stamped iron rods or caps carrying the surveyor's license number, and we flag them so you can find them. The markers are part of the record — moving or destroying them is both a practical problem and, in most states, against the law.
No. A phone's GPS is accurate to several feet at best and isn't tied to your deed or the corner monuments, so the lines those apps draw are approximate and carry no legal weight. Survey-grade GNSS fixes a point to the centimeter against a reference network — a different instrument for a different job.
