Working Next to Westminster's Open Space
Hydroseeding in Westminster frequently takes place right next to protected land. The city began buying open space in 1985 after voters approved a sales tax for it, and it now owns more than 3,000 acres spread across every part of town, including Standley Lake Regional Park and the Westminster Hills area. When a yard or job site borders that land, the goal is to get grass established without sending soil or weed seed onto the open space.
Standley Lake is drinking water
Standley Lake is a 1,200-acre reservoir that now serves mainly as the municipal water supply for Westminster, Northglenn and Thornton. Projects that drain toward the lake or the canals that feed it deserve careful sediment control: perimeter silt fence, protected inlets, and seed and hydromulch placed on bare ground as soon as grading is done.
Earth dams and slopes
The lake's earth dam had major slides on its downstream face in 1914 and its upstream face in 1916. That history is a good reminder that bare, steep fill does not stay put on its own. Graded banks around Westminster homes and commercial pads get a stapled blanket or a sprayed bonded fiber matrix from us, not loose mulch.
Big Dry Creek and trail corridors
The Big Dry Creek Trail runs about 12 miles from the city's eastern edge to Standley Lake, and other trails follow Walnut Creek, Little Dry Creek and the Farmers' High Line Canal. Lots beside these corridors often look best with a native grass strip at the back that blends with the open space, and a turf lawn closer to the house.
Farm history
Westminster started as a farming community that struggled with Colorado's arid climate, and later developer C.J. Harris divided homesteads into small tracts for fruit farmers. Those small-tract roots mean some older lots are larger than typical suburban yards. For big yards we often suggest a mix of irrigated turf and lower-water native seeding.

Westminster Questions
My backyard opens onto city open space. What should I seed at the edge?
A native grass mix on the back strip usually blends better and uses less water. We can seed turf near the house in the same visit.
Why does sediment control matter so much near Standley Lake?
The lake is a drinking water supply for three cities, so keeping soil out of it and its feeder canals is important. We use silt fence, inlet protection and quick seeding to limit runoff.
Can you stabilize a steep bank behind a Westminster home?
Yes. We usually hydroseed and then pin straw blankets on the slope or spray a bonded fiber matrix so the soil holds while roots grow.
My lot is larger than most. Does all of it need irrigated grass?
No. Many owners keep turf near the house and use native seeding on the rest to cut water use.
