It's not a creek it is a brook (Hunt Brook) that runs through that stretch and it originates basically from a storm drain behind one of the trailer parks (I used to go into the storm drain with friends as a stupid kid growing up). While I applaud maintaining eco corridors, that whole stretch especially with the increased density needs a few more connections. At least one at 80th Ave and possibly 78th could go a long ways to improving general traffic in Newton.
Right now your only east-west routes between 140 and KGB are @ 74th and then 88th (until 84th is pushed through finally) but even with 84th that is 10 Surrey blocks or roughly 20-25 Vancouver blocks.
Could you imagine going anywhere in Vancouver and needing to go North/South 25 blocks before you could go East/West 4 blocks?
