Seeding New Ground Next to the Refuge
Hydroseeding in Sherwood is mostly about new ground. In 1911 the town had 350 people inside a one-square-mile limit; the Census Bureau now puts the city at 4.31 square miles. Each expansion brought new streets and subdivisions onto former farm and woodland in the Tualatin Valley, and each new lot starts as bare graded soil.
Next door to a wildlife refuge
The Tualatin River National Wildlife Refuge borders Sherwood, and its visitor center sits off Route 99W near town. The refuge started on a former dairy farm of about 400 acres and now covers about 1,856 acres of wetlands, meadows and woods. The idea was first pitched to the Sherwood City Council in 1989 as the Rock Creek National Wildlife Refuge.
What that means for a lot
Lots that drain toward Rock Creek or the refuge wetlands should keep their sediment at home. On construction sites we put silt fence on the downhill edge and inlet protection on nearby catch basins, then hydroseed disturbed areas so they are covered before the rain.
Builder and homeowner lawns
For builders we can spray front and back yards in one visit once final grade is in. For homeowners who moved into a new house with a rough, weedy yard, we regrade, add topsoil where it is thin and seed a new lawn.
A meadow option
The refuge's oak and grassland habitat is a reminder that not every square foot has to be turf. On larger lots, a native grass or wildflower mix on slopes and back corners cuts mowing and holds soil well.

Sherwood Questions
Our new Sherwood yard is clay and weeds. Can hydroseed fix it?
Yes, after prep. We knock down the weeds, regrade, add topsoil where needed, then seed.
Do builders near the refuge need extra sediment control?
Any lot draining to Rock Creek or refuge wetlands should have a barrier on the downhill side and covered soil before winter.
Can you seed several lots on one visit?
Yes. Spraying several finished lots together is efficient for builders.
Is a wildflower area hard to keep up?
It is less work than lawn: some weeding the first year, then about one mowing a year.
