Rye Brook really does roll — Pine Ridge Park tips away from the street, and half the lawns in the village lie on a gentle pitch. Rolling Hills Landscaping cuts them for what they are: mowing across the grade so the turf lies even, trimming around walls and plantings, edging the drive lines, refreshing mulch, cleaning a property down in spring and again once the leaves are finished falling. On a July evening with the mowers off and the hoses running, a graded lawn that reads smooth from top to bottom is a quiet accomplishment. That is the standard they hold to, yard after yard, up and down this side of Blind Brook.
