Notes de l'éditeur
- The Problem! Homes built in what used to be the historical stream channels. Capacity limitations in the system so the system can’t handle strong, flashy storm events. DWM prepared a integrated model that simulates the surface conditions based on what the combined system capacity.
- * Projects total. This is the first 6
- Good morning, I’m Andrew Schock from the Conservation Fund. Thank you all for inviting me to talk about collaboration in Green Infrastructure development – we are off to a good start by having all of you in the room at once! First let me tell you a little bit about The Conservation Fund.
- We facilitate real estate transaction for the Cities, States and Federal governments – In Atlanta we have helped to protect over 50% of the non-beltline greenspace since 2005 – with more on the way
- But this is only successful because of the collaborative partnerships
