Victor Ballestas is back in Bay Harbor Islands to finish what he started a decade ago.

In the past two years, the Integra Solutions LLC principal acquired a large portfolio of multifamily properties he’s wanted since 2004. He’s now at work on one of the two islands that make up the small town between Aventura and Miami Beach. Ballestas is parceling out the 16 lots to develop a $40 million high-end residential project.
