Coronado's trees are part of what makes the town, some are designated heritage trees, and nobody's suggesting they go anywhere. But their roots have spread under the Village for decades, and the original clay sewer lines still under many of Coronado's historic homes leak moisture at century old joints, which draws the roots in. When a root gets into one, it grows slowly and out of sight. The first sign is usually a drain that stops draining.
Clearing them helps for a while, but roots tend to grow back through the same opening, and on an island where every service visit crosses a bridge, repeat visits get old fast. The longer term answer starts with the camera helping identify the entry point, the joint, the crack, the seam, and continues with closing it. In Coronado's older lines, that's sometimes one joint and sometimes a section, and the footage shows which it is. Nothing gets proposed that the evidence doesn't support.
Everything lands in plain English, the findings, the options, the tradeoffs, and the decision stays yours, made at your pace. The work is performed by or under a licensed contractor when you're ready.
