Thanks, Kent. I believe we already have Icon's original topo. We need to supplement that further upstream because we are looking at hydraulic impacts. That's why we need access. Also, the grading has changed next to the bridge so we need some shots on the current conditions so we know what we're tying into. I will send you an aerial photo of where we need access and to what extent. Please still forward me whatever you get from Joel in case for some reason we don't have it. We appreciate your help.

I understand that you have requested property access upstream of the bridge to perform some topo work. I reviewed a drawing last week from ICON which showed some contours upstream of the Bella Bridge which indicated to me that some survey work had been performed in this area. I have requested from Joel any survey information upstream which he may have from the park project. I will keep you informed of my findings. I am also beginning our contact with the adjacent property owners you requested should the information ICON has is inadequate for your needs. Could you please explain where exactly you need permission and access. A pdf showing the area would assist us in explaining to the owners your needs. Let me know if you have any questions. THANKS !
