Watering 250 Acres of Grass

With limited time to close and demolish over one and half miles of concrete runway, add new utilities, lay asphalt, pour concrete, groove, stripe, and flight test, we had to hydroseed (bonded fiber matrix) as soon as an area was completed. The plan was to have at least 85% grass cover going into fall and winter. Water trucks were fitted with used adjustable fire nozzles purchased on Craigslist; the original nozzles on the trucks were for flushing, not watering grass. We managed to exceed the goal of 85% cover on about 90% of the project. We hydro-seeded the rest of the areas in early winter knowing the grass wouldn’t grow. Fortunately, we had modified the storm system to collect any turbid runoff from the areas not stabilized and treat it with Chitosan-enhanced Sand Filtration systems.

Straw Wattles at Bryce Canyon National Park in Utah

Straw wattles installed on roadside slopes at Bryce Canyon National Park in 2004 still function to hold back erosion and allow vegetation to establish in a harsh, high altitude environment.
