Drainage problems usually reveal themselves gradually. Standing water that lingers a day after rain might seem like a minor annoyance. But repeated saturation cycles damage turf, erode soil, attract pests, and can eventually threaten the foundation. Knowing what to watch for — and when to take it seriously — can save significant money and headaches.

Garland sits just northeast of Dallas, one of the larger and older suburbs in the Metroplex, with most of its rapid growth occurring from the 1950s through the 1980s — well before the more recent booms in Collin County suburbs like Frisco or McKinney. That means Garland's housing and drainage infrastructure spans a genuinely wide range of eras, from older postwar construction with drainage systems well past their intended service life to more recent development on the city's remaining edges. Dallas County's blackland prairie clay is among the most expansive and moisture-reactive soil types in North Texas, and Garland's status as a dense, largely built-out inner-Metroplex city means less undeveloped land is available to absorb stormwater runoff during North Texas's periodic intense rain events than in the newer, more spread-out outer suburbs. The city's older 1950s-60s core, built well before Collin County's newer suburbs existed at all, still carries the drainage infrastructure standards of that earlier era.

Common Drainage Warning Signs

These are the signs we hear about most often from Garland homeowners:

Standing water in the yard more than 24-48 hours after rain

Water that doesn't drain within a day or two usually points to a grading or subsurface drainage issue rather than just a heavy storm.

Water pooling against the foundation or in a crawlspace after rain

This is one of the more urgent drainage signs, since prolonged moisture against a foundation can contribute to other structural issues over time.

A consistently soggy low spot in the yard, even during normal weather

A chronically wet spot (as opposed to a spot only wet right after heavy rain) is often solved with a French drain or rain garden rather than regrading alone.

What Causes These Problems

Most drainage problems in Garland and Dallas County come down to one or more of three conditions: soil that drains slowly (clay is the primary culprit in this region), low spots in the grading where water naturally concentrates, or runoff from neighboring lots, driveways, or roof drainage that overwhelms the yard's capacity to absorb. Identifying which condition applies determines the right solution — and a proper assessment before any work begins is the only way to get that right.
