I thought we were pretty much done with this round of changes, except for the railroad area. I wouldn't know what else could be done.
My take is that, as Folsom has grown and developed more and more competing areas, Sutter St. will never be more than it is now: a place that some people choose to frequent by day, and others by night, but which will never again be a shopping mecca. I personally go there for four reasons: (1) to have a leisurely Farmer's Market visit on random Saturday mornings, followed by a stroll along Sutter (but no shopping except the produce); (2) to go to Hop Sing's two or three times a year on a weeknight; (3) to very rarely check out one of the other eateries (I would say Snooks, too, but I'm on a diet); (4) to attend rare events (not Folsom Live), such as the Christmas tree lighting. All in all, I seem to find myself strolling along Sutter once a month or so, but I don't buy anything from the shops. Yet I wouldn't know what else to do with Sutter St., unless it became a full-on Wild West re-creation (like Columbia), for two blocks, which I sincerely doubt would ever be done.
All of the reasons you visit are great ones. There is something for everyone. There's the history museum and pioneer village, a fair amount of restaurants and bars, clothing shops, home decor, art, and specialty foods.
I go there probably once per week or more, whether it's coffee at the Black Rooster, a drink at Scarlet's (6-8pm $5 martinis), getting candy from Snook's (heading there shortly to pick up some Habanero Salted Caramel to take to my sister), pizza, breakfast at Sutter Grill, or a play, I truly enjoy hanging out down there.
Geesh, I guess nature isn't pretty enough unless we manicure it.
If the idea is getting families to Sutter St., I think a nice fountain with benches would have been one way to entice them to visit. Last time I was in Savannah the riverfront looked kind of depressed, lots of bars and restaurants. In contrast, Ellis Square was buzzing with activity and a lot of families out enjoying an evening. I'm not entirely sure little ones and a cold, fast-moving river are the best mix. Plus, there is the traffic noise up above from Lake Natoma Crossing.
The problem with access to the lake is one can't do it without a lengthy walk or getting dirty. I think the plaza on the railroad block will become more of an attraction as it is built out.
