Bad LOMA?

Discuss it with my local FEMA Floodplain Administrator.

First order of business is check your work. Being wrong sucks more after you publish it.
If i knew who did the work i would call them and talk. An insurance company will come after them if they pay a claim. An owner will come after them if they dropped flood insurance due to a misleading LOMA. At the end of the day the LOMA wont cause or stop a flood but it will change who pays for a loss.

[SARCASM]Wow, shoulda thought of that myself[/SARCASM]

Sorry, couldn't resist.

No idea who did the work; really don't want to spend the time to track it down, though I strongly suspect a local RTK wizard. What's got me PO'd is having to explain to my guy why he's still in the SFHA, & the neighbor, with a nearly identical LAG (per my DOUBLE-checked-and-verified-against-recent LIDAR-data measurements) is out.

Also, imagine how popular I'll be if I cause an existing LOMA to be rescinded.

Sometimes it's just best to leave sleeping dogs alone. 😉

Quick Q:
What are the abbreviations?

LOMA: Letter of Map Amendment
BFE: Base Flood Elevation
LAG: Lowest Adjacent Grade

just 'suck it up'. We had to do same more than once where adjacent parcels were removed and were lower than my Client. Check your data but also check into other data. RTK could be/should be tied to a high accuracy reference point. Who checked the LIDAR elevations relative to local benchmarks and to HARN? Your elevations could both be correct, just tied to different datum or reference points.
