Valley Stream sits low and level on the south shore, sandy underfoot, close enough to the bay that a south wind carries a little salt down the block. Green Valley Landscaping works that flat ground the way it deserves — mowing on a steady weekly turn, running the strip along every sidewalk, trimming tight to fences and stoops where a deck can't reach. The growing season here is long, greening early along the stream corridor and holding well past the first cool nights. Autumn brings the leaf work, then a final tidy cut that leaves each block looking even from one driveway to the next. On a street of close-set homes, one well-kept lawn lifts the whole row.
