Yes; it is mown two or three times in the mid and late summer, but allowed to grow in the spring before the grass gets very long; both to allow wildflowers to grow, and also to reduce the disruption to traffic by having a low number of mowings per year (for safety, they have to close off a lane on either side while mowing is in progress) and to reduce costs too.
Here too, the City of Vancouver has set aside areas along boulevards that are treated similarly. I think they go one step further in planting select plant species in those areas. Pollinator meadows | City of Vancouver
