Stars to shine at City Hall during centennial shindig

This is going to be a blockbuster week for our city.

For starters, we’re playing host to 400-plus mayors from all over the country at the U.S. Conference of Mayors’ annual meeting. They’ll have a photo opportunity with President Obama one day and maybe with Hillary Rodham Clinton the next.

Both of these political superstars are coming to town to raise money. And why not? We seem to have plenty of it these days.

Of course, the real fun comes when we celebrate the 100th anniversary of our beloved City Hall on Friday.

For my money (and, thankfully, your tax money too), it is the most magnificent local government building in the country. It’s eclipsed only by the U.S. Capitol itself in its grand design.

I got a sneak peek at Friday night’s program, and while I can’t go into the details, suffice it to say that the celebration will be incredible.

It’s all free, so everyone can see what event planner Stanlee Gatti does with the place, without shelling out the big bucks that are usually required to get into a Gatti party.

By the way, not one public dime is being spent on the centennial shindig. So come on down to the People’s Palace and partake.

I just saw my first campaign brochure for the November election. It has Mayor Ed Lee on one side and former Mayor Art Agnos on the other, both endorsing the Giants’ proposed high-rise development next to AT&T Park.

This is one waterfront project that needs to go forward. It looks like the trick will be convincing the voters that the amount of housing in the development set aside as below-market rate — 33 percent — is enough. Knowing Giants President Larry Baer, he’ll close the deal.

What a brilliant comeback by Police Chief Greg Suhr.

First, I read in The Chronicle that District Attorney George Gascón is ripping into the chief for refusing to go after a federal grant that would pay for processing backlogged rape-test kits at the city’s crime lab.

Suhr stumbled out of the gate, saying the lab was too messed up to do the job, and besides the cases were too old to prosecute.

After reading his own words, Suhr said OK, we can do this with our own money.

It will all be done by the end of the year.

I have no idea how this little spat got started, but it’s obvious that the D.A. and chief don’t have much of a relationship right now. Can’t wait to see who throws the next punch.

At Marin Country Day School in Corte Madera, Wednesday’s graduation ceremony was held outside. It’s June, so everyone figured the weather would be great. Instead, we got rain.

We were all so grateful for the downpour in the midst of the drought — I was there for my daughter Sydney’s middle-school graduation — that no one popped an umbrella. Just lots of plastic. And interestingly enough, nobody’s hair seemed to be out of place when it ended.

Then it was off to D.C. for a summer trip with Sydney. U.S. Treasurer Rosie Rios paraded us through the entire production process involving dollar bills. Of course, I was more interested in the samples, which never came.

By the way, when it comes to traffic and transportation, Washington is as bad as San Francisco. It is bumperto-bumper everywhere.

The difference is that in D.C., no one is driving a Prius and everyone seems to know where they are going.

Side story: I saw a guy in a Prius in San Francisco last week with a GPS on the dashboard. I asked the guy, “Where do you live?” He says, “San Diego.” “San Diego?” “Yeah. I make my living by being up here three really busy days a week. And then after that, I go back. I do it every week, and I’m making it.”

Movie time: “Spy.” Melissa McCarthy, Jason Statham and Jude Law obviously had a lot of fun making this James Bond spoof. The stunts are good, and so are the jokes. Worth the admission price.

Great line from one of my street people: “Caitlyn is a trans-Jenner.”
