The developer of the massive $1 billion Metropica project envisioned for Sunrise faces a lawsuit in a dispute over a shared strip of land.

City commissioners gave Metropica Holdings LLC final approval Tuesday evening to build its mixed-used development off Sunrise Boulevard in the heart of the city’s retail sector. The 65-acre project has entitlements for nearly 2,400 residential units, 650,000 square feet of office space and 485,000 square feet of commercial development.
