What Makes Signal Hill Different
Signal Hill is its own city inside Long Beach, and it rises well above the flats around it. On a slope, water runs off before it soaks in, so short watering cycles and drip work better than big spray heads. Terraces and low retaining walls can turn a tilted front yard into space you can use.
The Ground In Signal Hill
USDA maps this as Typic Xerorthents, a type marked as moved by people, over Typic Haploxeralfs. Both run about 6 to 10 percent clay and drain well.
- Graded soil changes from one spot to the next, so dig a few test holes before you design.
- Look for buried rock or old debris before you price a trench.
- Some of this ground slopes, and water on slopes needs to move slowly. Drip works better than spray.
