Awful article.
1st of all, the stadium proposal cited is NOT the current Chargers proposal. It's a proposal the Union Tribune (SD's newspaper) did. The current site proposal is close to the bay but it's not adjacent.
2nd, the stadium would be a vast improvement over the "port" we have. This is how it looks right now.

Having the stadium will actually improve access to the bay.
For the Midway proposal, the current plan is to put a park "lid" over the pier which is currently home to a parking lot. Again, the park is an improvement over a parking lot. The last part of the proposal includes something iconic at the end of the pier. Currently they're proposing the "Wings of Freedom" statue. Hopefully they can find something else to put on there but it's a perfect place for something iconic.
I also like how the author fails to mention the North Embarcadero Visionary Plan, or the Lane Field development, or the Navy Broadway Complex redevelopment....all which will have a dramatic effect on our waterfront.
