From the press release:
"The pilot project means sidewalks for residents and businesses in areas that have never had sidewalks; new sidewalks in others; ornamental streetlights; and planter strips featuring 100 trees, 200-plus shrubs and 4000 perennial grasses planted over a new storm drainage system, instead of a traditional curb and gutter. Also, instead of a typical mow strip, several planter strips double as detention basins for storm water runoff to collect and percolate through the soil before it flows into nearby streams and rivers. Fences were repaired or added to complement the new walkways."
