September evenings over the Tualatin Valley go amber and dusty, the light coming in low across the Hillsboro flats and the fields out past Rock Creek. Flores A Construction/Lawn Maintenance LLC keeps mowing straight through that stretch, when lawns are worn down from August and the first cool nights start pulling the color back. The cut is followed by trimming and by edging that squares the turf against walks and drives. As fall sets in, those same yards get their seasonal cleanups — summer's dead growth and the earliest leaf drop taken out before the rain glues everything to the ground. It is plain work done in order, and from the curb you can see it was done.
