Plan A
Find an unstable sandy coast line . Build a town around but set back from the beach . Create blocks with absolute water front views , Rate them Up the Wazoo for the great view . Quote the owners a huge price to put in a sea wall to protect said unstable sandy coast line block so they louse interest . Wait till the 1 in 100 or 30 year storm , then say its your fault for not coughing up to get the sea wall done .
Plan B
When it turns to SH1T run & hide , quickly .
