Gophers, those small burrowing rodents often seen as harmless creatures, can surprisingly cause significant damage to the environment. Among their destructive activities, gophers’ tunneling can have far-reaching consequences, leading to a phenomenon known as “slope creep.” This article explores how gopher tunneling affects slopes over time and the subsequent repercussions on hillside adjacent patios, causing settlement and potential damage to patios, swimming pools, and hillsides.

Understanding Gopher Tunneling

Gophers are adept at creating extensive tunnel systems underground as they burrow through the soil in search of food, shelter, and protection. These tunnels consist of both shallow and deep passages, with the deeper tunnels often reaching several feet beneath the surface.

The Impact of Gopher Tunneling on Slopes

Slope creep refers to the gradual movement of hillsides due to various factors, such as gravity, soil composition, and environmental conditions. Gopher tunneling introduces another critical element to this equation. When gophers burrow into slopes, they disturb the soil structure and create cavities, weakening the overall stability of the hillside.

The Role of Water

Water plays a crucial role in exacerbating the effects of gopher tunneling. When rainwater or irrigation seeps into gopher tunnels, it saturates the soil, significantly reducing its strength and increasing its weight. The combination of weakened soil and increased water content creates a perfect recipe for slope movement and settlement.

Damage to Hillside Adjacent Patios

Hillside adjacent patios are particularly vulnerable to the damaging effects of gopher tunneling. As the hillside gradually moves and settles, the patio’s foundation may shift or tilt, leading to cracks and uneven surfaces. Over time, these issues can worsen, compromising the integrity of the patio structure and rendering it unsafe for use.

Implications for Swimming Pools

Swimming pools located near gopher-infested hillsides face similar risks. Slope movement caused by gopher tunneling can exert pressure on the pool’s foundation, resulting in cracks, tilting, or even structural collapse. Additionally, as the ground shifts, underground plumbing lines connected to the pool can be damaged, leading to costly repairs and water leakage.

Erosion and Landslides

Gopher tunneling not only weakens the soil but also increases the likelihood of erosion. As water infiltrates the tunnels and saturates the soil, it erodes the surrounding materials, further destabilizing the slope. In extreme cases, prolonged erosion and the loss of soil strength can trigger landslides, posing significant dangers to nearby properties and inhabitants.

Prevention and Mitigation

To protect hillside adjacent patios, swimming pools, and hillsides from gopher-induced damage, preventative measures are crucial. Homeowners should consider implementing gopher control methods such as trapping, exclusion barriers, and habitat modification. Regular monitoring of the property for gopher activity is also advisable, allowing for timely intervention before extensive damage occurs.


While gophers may seem innocuous at first glance, their tunneling activities can have far-reaching consequences. Slope creep resulting from gopher tunneling poses a significant threat to hillside adjacent patios, swimming pools, and the overall stability of slopes. Awareness, proactive gopher control, and early detection of slope movement are essential for safeguarding properties against these hidden dangers. By understanding the risks associated with gopher tunneling, homeowners can take necessary precautions to preserve the integrity of their patios, pools, and hillsides for years to come.
