Low ground and river soils
Hydroseeding in Avondale often starts with a soil question. The city sits at about 974 feet, low ground compared with much of the metro, where the Gila River crosses the southern part of town and the Agua Fria joins it from the north. River-bottom ground can grow a great lawn, but it can also carry salt that burns young seedlings if it is not checked first.
Floodplain soils and salt
USDA describes the Gilman series, typed in Maricopa County, as a stratified stream alluvium found on flood plains and alluvial fans, and notes it can range from nonsaline to strongly saline. We do not assume every Avondale yard is salty, but on low lots near the rivers we look for white crusts and poor growth, and we can recommend a soil test before new lawn installation. Leaching with deep watering and adding organic matter help where salt is present.
Farm heritage
Avondale was a farming town with fields of alfalfa and cotton, plus ranching and the railroad. In the 1880s Coldwater was a stage station near the Agua Fria crossing. Old fields are often well leveled, which suits grass seeding once compaction is broken up.
Survey point of the Valley
Monument Hill, at 115th Avenue and Baseline Road, holds the survey marker for the Gila and Salt River Meridian. It is a reminder that this part of the Valley was surveyed and farmed as flat river land, and that flat ground needs built-in drainage.
Fast growth
Avondale's population grew more than 114 percent in a decade and is projected to pass 100,000 by 2030. Many newer homes have bare backyards waiting for lawns, and builders working near the river channels need silt fence and sediment control during grading.
Monsoon rains
The North American Monsoon brings afternoon and evening storms in July, August and early September. Snow is rare, though winter lows occasionally drop below freezing, so fall overseeding is the usual way to keep color through winter.

Avondale Questions
How can I tell if my Avondale soil is too salty for grass?
White crust on dry soil and stunted growth are clues. A soil test is the reliable answer, and we can help you decide whether one is worth it.
Can salty soil still grow a lawn?
Often, yes. Deep watering to push salt down, organic matter and a salt-tolerant grass like bermuda all help.
Do builders near the river need extra sediment control?
Sites draining toward the river channels should have silt fence and protected inlets during grading.
Will my lawn stay green in an Avondale winter?
Bermuda goes dormant in cool weather. Overseeding with ryegrass in fall keeps it green.
