Separate irrigation leakage from wet-ground complaints.
In a San Marcos yard, wet soil does not by itself identify a broken sprinkler line. Record whether the wet area develops during irrigation, after rainfall or continuously. Compare the timing with the controller program before authorizing excavation, particularly where the City’s drainage resources identify a broader site concern.
Provide the controller location and any valve map, and identify zones that no longer match the planting layout. A repair estimate should distinguish fault finding, component replacement and surface restoration. For a commercial property, agree who can authorize additional work if hidden damage is discovered, and schedule testing so overspray does not interfere with entrances or customers.
