How category 3 water damage works in Mira Mesa

Mira Mesa water damage is shaped by the area's 1980s tract-build timing and the dense multi-family stock along the commercial corridor. That local housing mix shapes where we look first for this scenario.
Why category 3 water damage shows up in Mira Mesa
Category 3 work around North Park, La Mesa, Lemon Grove, and National City includes sewage and outdoor water tied to pinhole copper leaks and Cat 2 drain backups.
