As the weather is warming up, there’s plenty more to do around the region than soak up the sun at a sidewalk cafe. (Though, you should do that too.) Mark your calendar for great activities around the region this week and beyond.

Affordability with APA: Talk affordable housing for Montgomery County Tuesday 4/7 (tomorrow) at 5:30 pm with Praj Kasbekar of the Montgomery Housing Partnership. The event is part of the American Planning Association’s “Tuesdays at APA” series at 1030 15th St NW.

After the jump: Tactical Urbanism, federal transportation policy, and more.

Tactical Urbanism: Spaces are filling up fast for our free book talk with Tactical Urbanism co-author Mike Lydon at 6:30 pm on April 21 in Brookland. We’re co-sponsoring the talk with Coalition for Smarter Growth, CNU-DC, and Island Press, so be sure to mark your calendar and snag a space before they’re all gone!

Federal transportation reauthorization: Talk about the upcoming reauthorization of the federal MAP-21 transportation program over wine and cheese at the American Public Transportation Association’s Transportation Tuesday series, Tuesday 4/7 (tomorrow) at 5:00 pm. Hear from keynote guest Governor Jim Gilmore, President & CEO of the Free Congress Foundation (FCF). RSVP requested to cowens@apta.com.

Potomac Yard Metro: Alexandrians awaiting the infill Potomac Yard Metro station can rejoice: the next step is here! Last week, officials released the draft environmental impact statement for four alternative locations being considered. Public comment on the alternatives is open through May 18, so why not weigh in Wednesday, April 8 at 6:30 pm at the latest public meeting?

Purple Line in the legislature: At this month’s ACT meeting on April 14, join Maryland Delegate David Moon (District 20) for a briefing on the latest about the Purple Line as this year’s Maryland legislative session comes to an end. ACT meetings are the second Tuesday of the month at the Silver Spring Civic Center, beginning at 7:30 pm.
