Is my slope sliding? Why?
The hilly and wet Pacific Northwest region provides the perfect conditions for landslides. Often these problems are exacerbated by poor site drainage, unchecked removal of vegetation and improperly compacted fill. If you have noticed any signs of an unstable slope on or near your property it is imperative that you remain vigilant in assessing the slope conditions. Conditions can change quickly and pose extreme life-safety issues if not addressed properly by a professional.
LANDSLIDE WARNING SIGNS:
- Cracks or unusual bulges in the ground, street pavements or sidewalks.
- Soil moving away from foundations.
- Structures such as decks and patios tilting and/or moving relative to house.
- Tilting or cracked floors/foundations.
- Broken underground utilities.
- Leaning poles, trees, walls or fences.
- Offset fence lines.
- Sunken or down-dropped road beds.
- Water saturated soil on a slope.
- Sticking doors and windows.
- Unusual sounds, such as rumbling, trees cracking or boulders knocking together, might indicate moving debris.

Our Work
The engineers at CG provided us with city-specific standards to implement into our work so their drawings could obtain approval. Because of their project management and coordination efforts we were able to provide a geotechnical report to suit the site’s specific needs.”
