Chris,

Have you considered Western Red Cedar along the highways. Here in  
Texas I have been planting Eastern Red Cedar and it is really hardy,  
fast growing and exudes a lot of organic debris over the year. That  
should help build soil carbon while making a harvestable product. I  
also plant a lot of clumping bamboos, such as Timber Bamboo. It too  
creates a lot of extra biomass and can be harvested for many  
applications. Planting the understory with grasses such as wheat, oats  
and rye and red and white clover really improves the surrounding soil  
and increases fertility.
