Certificate Sketches and Delivery
We use CAD for any supporting sketch the certificate needs. We deliver the sealed certificate for your insurer or floodplain administrator.
Should You Pursue a Letter of Map Amendment?
We advise whether a Letter of Map Amendment is worth pursuing for your property. Ask us about that decision before committing to a filing. We do not promise a map amendment or an insurance savings amount.

Re-certification After a Change
We charge $250–$500 per re-certification after a change. If your property has changed since the certificate was completed, tell us what changed when you ask about re-certification.
Soil Conditions and Site Work
The Melrose soil series is deep and well drained, with loamy outwash over clayey deposits. Soil conditions can change across a lot, so we do not assume one corner represents the whole site.
That soil series is classified as hydrologic group C and potentially highly erodible. During site work, we pay attention to runoff and disturbed ground rather than treating “well drained” as a reason to ignore them.
Hard winter freezes drive freeze-thaw cycles that stress foundations, slabs, and buried pipes. If you are planning work around those parts of the property, keep that seasonal stress in mind.

FAQs
A survey establishes where the line legally sits based on the deeds and the monuments of record, and the sealed plat is the professional opinion a court relies on. It won't force your neighbor to agree, but it replaces guesswork with a defensible, licensed determination, which is usually what resolves the dispute or supports it if it goes further.
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.
More Questions We Hear
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.
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.
