Open Question: Geography project: a futuristic redevelopment of a neighbourhood with an environmental focus?

It’s supposed to be like Masdar City.
The neighborhood is roughly 2.1 km x 2.2 km.
I have to develop a ‘vision’ for each area of focus:
1. Residential and Commercial (design a physical layout of the neighbourhood’s homes and businesses to be self-sufficient-so, like, build grocery stores close to homes)
2. Transportation and Communication (design the networks that will carry people and information in an efficient manner)
3. Energy Use and Waste Management (design the neighbourhood’s inputs and outputs to be renewable and non-pollutive)
4. Sustainability (design natural resource management strategies that ensure conservation and the 3 R’s)
5. Tourism and Recreation (design cultural attractions and opportunities for tourists to engage in eco-tourism. Offer specific case studies of existing Green urban planning that have put similar environmentally focused strategies into action i.e. carpool lanes, green bins, etc)
I mostly need help with 2. Transportation and Communication (just the communication part. How do you make communication environmentally friendly..?) and 5. Tourism and Recreation (I don’t really understand eco-tourism). Best answer definitely goes to anyone who offers the most help. I need help with it ALL (I have no idea how to go about doing this project), but mostly 2 and 5.
I apologize if this is in the wrong section, but I think it has more to do with conservation than homework help…
Also, I need help with natural resource management (wasn’t part of my question, but it’s in my project). The only natural resource I can think of right now is water (what others are there?): How could I reduce water use other than promoting it? Is there something I could physically do? Like, create whole new water system? What would the water system be like? Thanks in advance…
