Looking for a specific map need a seed please

[dragonsphotoworks]

Im trying to play a speecif type of map. I like open large maps so i can build huge colonys. but i have to keep retrying maps as they keep putting in tomuch water or mountains. What im looking for is:
largest map
Flat land as in no mountains. Or atleast only mountains on one side, not going deep into map.
Water limited to one side like a beach.

When i try find this i always end up with mountains all over. Or swamps/lakes all over. Id love a map thats 325x325 with mountain on west side. And ocean on east side. North and south can be open. I want to be able to plant lot of crops and trees. Kinda want to pretend washed up on a beach and a cliff is keeping me from going inland. can only go up or down beach. Dont need roads or rivers in it either.

Any one have some suggestions for a seed? Tried to google and all i can find our mountain maps :-(

Why not use Map Reroll mod? I got the map I want with that.

Havve only seen one mod like that and it just has settings. Doesnt reroll anything. Not sure which you mean.

Map reroll works well for this. Just keep rerolling till you get the one you want
