Would you allow higher densities with increased efficient transit service?

Even I don't live in here, exactly, I often shop here, and I just graduated from A.P. Giannini, which is located here. I believe that our responsibillity is to increase sustainable forms of living, and sustainabillity includes efficient transportation. Even though this district that I love has its virtues of quietness and neighborhood cohesion, I belive that it wouldn't hurt to allow 5 to 8 story buildings along Irving, Judah, and Taraval Streets in the Central Sunset, and to elevate the N and L lines. As you know (hopefully), the N line is already overcrowded, and I believe it would help to grade-separate those lines. Also, the taller buildings would allow office space, more retail, and more residents, thus more local jobs and opportunities for improvement. The new units would also help fund the elevation of the metro lines. For those who want the old Sunset, don't worry, large swaths outside of the main corridors will remain untouched.
