Skye knows her fellow Arrow will be in the area and part of their planning could have easily include a options for meeting points so as she moves between these Asclepius can be located more by virtue of she knows to look out for him. However the water ways fall into two categories, underground for anything old and large enough for a person or sealed yellow and blue pipes above ground made of some hard plastic as for a park well there certainly is not any thing here.
Skye can make a intelligence + composure roll to see if she can recall what Guru said and where she might be getting confused.
Asclspius's spell fizzles, maybe its the worry? maybe its all the moving parts of the plan but he just cant bring his will to bear in this moment. As he heads over towards the building he can see Skye making her way over finally.
If he wants to attempt to the climb its two athletics+ strength-3 each roll needs 2 suxx failure on the second roll will result in him falling! He can of course employ magic, relevant equipment etc to help himself.
