Northwest San Antonio · ZIP 78230
78230 covers Oak Hills, Colonies North and the neighborhoods around Phil Hardberger Park — established, well-treed north-west San Antonio built out mainly from the 1960s through the 1980s, sitting in the upper Salado Creek drainage.

1960s–1980s single- and two-story homes on slab, on generous lots with heavy mature oak cover. Original plumbing in the earlier sections is now beyond 50 years, and the tree canopy that defines these streets is directly implicated in sewer lateral damage.
Mature oak root systems intruding into clay and cast-iron sewer laterals are the single most common non-storm cause we see here. Salado Creek's upper tributaries cross the ZIP and flood locally in heavy rain. The rocky, shallow soils of this part of the city also concentrate surface runoff rather than absorbing it.
The losses we attend most often in this ZIP:
Water running right now? Shut it off at the main if you can reach it safely, cut power to affected areas at the breaker if water is near outlets (never stand in water to do it), photograph everything before moving anything, then call (844) 476-1017. Our north side branch dispatches to 78230 around the clock.
Water damage frequently leads to mold, and fire losses almost always involve water too. We handle all three from the same branches: mold remediation with containment and independent verification, and fire and smoke damage restoration including emergency board-up.
Yes, and it is one of the most common causes of sewage backups in this part of the city. Roots seek moisture, find hairline cracks or joints in clay and cast-iron laterals, and then expand inside the pipe until it blocks or breaks. It is not a reason to remove mature trees — but if your house is 40-plus years old with large oaks over the line, a camera survey is worth doing before it backs up into the house.
That usually means surface water is collecting against the foundation rather than draining away — a grading, gutter or downspout issue, and common on the rocky shallow soils here where water sheets rather than soaks in. We dry and treat what has entered and identify the entry path; correcting the fall and extending the downspouts is what stops it recurring.
The park area sits within the upper Salado drainage, and the tributaries running through this part of the ZIP do produce localized flooding in significant rain events. Whether your address is exposed is worth confirming on the county flood maps, particularly for properties backing onto a drainage easement or creek channel.
