Well, radiant heat increase can be a big deal, I suppose-particularly in hot areas. In addition, wonder if there is chemical off-gassing that can occur. Hmm, native plants, sand, rocks sound like better options then.According to some info I read, artificial turf can increase the radiant heat as much as 6X compared to real grass. This leads to a heat island effect in areas where artificial turf is used. How much artificial turf actually increases the heat was not discussed, so when you read things like 6X, you have to ask yourself how much the temp is affected. Also, it ignores the benefits of artificial turf such as never needing to be watered, which I think should be a major consideration if the town is on water restrictions.
