On the off chance you haven’t had enough of my opinions from reading Greater Greater Washington, tune into WAMU now listen to today’s Politics Hour, or a Smithsonian seminar tomorrow morning. There are also many great events coming up around security at federal buildings, Maryland transportation, bicycling, DC historic preservation and more.

The Politics Hour (now): From 12:30 to 1 pm, I’ll be a guest on WAMU’s The Politics Hour. You can listen live here, and the archived audio will be posted this afternoon has been posted; jump to the 35 minute mark for my segment.

Greening Greater Washington (Saturday): Tomorrow, the Smithsonian is running a seminar called “Greening Greater Washington,” and perhaps in recognition of the name’s similarity to a certain blog, I’m giving the morning keynote.

The whole day will be streamed live, and we’ll have a post up Saturday morning with the video. My talk starts at 9:55 am.

Other panels will follow, with many great people including Stewart Schwartz of the Coalition for Smarter Growth, Arlington County Board Chairman Chris Zimmerman, DC and Montgomery County planning directors Harriet Tregoning and Rollin Stanley, Councilmember Tommy Wells, and Brookings scholar and author Christopher Leinberger.

Hack Day: Saturday is also the Mobility Lab’s Hack Day for coders interested in working on projects that help people better understand their transportation choices or otherwise using open transit data and open geo data to make better tools.

Next week are several interesting forums that explore key issues in our region.

Redefining security (Monday): NCPC is conducting a forum on September 12 about redefining security a decade after 9/11. How can the federal government balance its security needs with the responsibility of creating useful and accessible public spaces?

The forum is 6:30-8 pm at the US Department of Commerce Auditorium, 1401 Constitution Avenue NW (enter through the main doors on 14th Street). RSVP here. And in advance of the forum, NCPC has a page where you can submit examples of great or examplary or abhorrent security facilities in the region.

Maryland transportation funding (Tuesday): This month’s Action Committee for Transit meeting, on September 13, will focus on Maryland’s transportation funding challenges.

WABA regional stakeholder meetings (Tuesday): WABA also kicks off a series of regional discussions with stakeholders, to set its priorities and lead up to a big November 3 summit. The first one, on September 13, is in Greenbelt, followed in successive weeks by Kensington, Shirlington, Alexandria, DC Ward 7 and Vienna.

Historic preservation plan (Tuesday): DC’s historic preservation office is updating their 5-year historic preservation plan, and wants public input. You can read draft goals created by HPO and bring your input.

Park(ing) Day (Friday): Park(ing) Day started as a guerrilla street project to temporarily turn a street parking space into a little park. Efforts to legally bring it to DC encountered ridiculous bureaucracy, but this year Casey Trees is organizing their own little park at New Hampshire and Q, NW from 8 am to 5 pm on September 16.

Go car-free, try transit: The following Friday is Car-Free Day, where people pledge to go car free for the day of September 22. You can sign the pledge even if you already won’t use a car that day.

In case you read this blog but haven’t tried transit, the entire week is Try Transit Week with its own pledge; a lucky pledger could win a year of free transit or free trips on Amtrak.

And…: Other events next week include book talk on Brooklyn gentrification (Tuesday, $18), and a public meeting on the Virginia Avenue tunnel (Thursday).
