Temperatures can be below freezing when concrete is being poured nearly half the year, and a lot of time it's not feasible to wait for warmer temperatures, so that leaves 2 options. 1 use a specific mix or 2 use hoarding and heat the area. If you are doing a sidewalk, then it's not feasible to hoard and heat it so you have to use a special mix.
That being said, there is no excuse for the concrete in a high profile area like Memorial park to be cracking and spalling already, so there was something wrong with either how it was mixed or poured and whoever screwed up is probably eating the cost.
