Looking for a seed to serve as a good baseline to minimize terraforming work

Hey everyone,

I'm starting a large military build project in Minecraft Bedrock and I'm trying to find a good seed to start with.

The main focus right now is building:

• Naval Air Station on an offshore island

• Large Naval Station / harbor on the mainland

I'm looking for a seed with terrain that fits a Southern California–style coastline.

Ideal terrain features:

Large ocean coastline

A wide bay or harbor area

Flat plains near the coast (for the naval base)

Enough ocean space nearby to build an artificial island for the NAS

Optional but nice: hills or mountains inland

The rest of the world will eventually include other bases (Marine, Air Force, test ranges), but those are future expansions.

I'm playing on Bedrock Edition (PC) and will be using WorldEdit, so minor terrain edits are fine.

If anyone knows seeds with:

large bays

good coastlines

flat coastal plains

please share them!

Thanks!
