I have thought a lot about this and concluded that I like the idea of moderate densities along select major corridors such as Lomas, Central, San Mateo, University, 4th St., and perhaps a bit more on West Central beyond the Rio Grande. I think most of those Boulevards and Streets are wide enough to support light rail or streetcars and most are lined with strip malls that could easily be converted to 3 to 6-story mixed-use developments. I really think this city has an opportunity to do something unique by United States standards by going with this style of development. Many citizens in our city enjoy the sunny skies and vistas that I think would be washed out by canyons of tall structures. This photo below is of Barcelona. I think this could be a terrific model for the area around Central and SanMateo with slightly lower densities elsewhere.

HOWEVER, I think there should be a line drawn around downtown where the sky's the limit. I don't foresee us ever building anything aboove 50 stories, and I'm not even sure that's a possibility with the soils and aquifer.
And lastly, speaking of possibilities; I think the post office facility at Lomas and Broadway will be the next major development in the downtown area. Hopefully the post office will see the potential for the area and decide to build a new facility sooner than later. I say we aim for 10,000 new residents and 5,000 new jobs downtown by 2015. What say ye?
