I'm not going to go into great detail, because I need to pace myself on the subject of parking or else I will pop a vein before Opening Day. But here's the gist: the city and the Nationals want to be able to build temporary surface parking to handle the estimated 3,800 cars that will need parking beyond the 1,225 spaces on the stadium site. These lots will be available as public parking during non-event times (so you DOT workers who want to drive to work should be paying close attention). This zoning request covers certain squares directly around the stadium and at Capper; apparently there will be a subsequent submission requesting similar amendments to the Southeast Federal Center Overlay to allow surface parking there as well.

As to why the Office of Planning is supporting this request, here's a quote from their report to the Zoning Commission (emphasis mine): "Although much of the parking needed to serve the Ballpark's patrons will eventually be accommodated by parking within nearby future buildings, these buildings will not yet be constructed when the Ballpark opens in 2008. While OP strongly encourages the use of mass transit and encourages the Nationals to provide meaningful incentives for the use of mass transit and other alternatives to the private automobile, OP shares their concern that a short term shortage of parking available to patrons could lead to illegal parking on streets and private property in the surrounding area, and could have an impact on the short term success of this important District facility. This proposal would help to address the short term need for an interim parking solution."

And, another OP quote (again, emphasis mine): "Normally, OP is not supportive of surface parking lots. In addition to being a poor use of the District's valuable land base, extensive surface parking lots disrupt neighborhood fabric; can be a source of crime, noise, trash, and light-spill; encourage the use of the private automobile over other less environmentally damaging forms of transportation; and contribute significantly to storm water run-off water pollution problems facing our great river systems. OP would not support surface parking on these squares as a permanent use to address currently perceived parking need."

For more background and explanation of OP's stance, I strongly suggest reading the OP report (specifically the last four pages).

And, against my better judgment, I have created a new Planning for Stadium Transportation and Parking page, pulling together the various documents that have been released recently (mainly from last month's TOPP meeting). I've also thrown together a map that is nowhere near official marking what I understand to be various possible locations for stadium parking. It will change as time goes on, and do not take it as gospel, but it does show which sites come under this zoning request, along with other possible sites. Opening Day is still a year away, and there will be much jawboning on this subject over the coming weeks and months. So, everyone take a deep breath, keep an eye on updates as more information gets released, and try not to panic too far ahead of time.

And remember that every organization in town really wants you to take Metro.

UPDATE: And with fine timing, Near Southeast's councilman Tommy Wells has just announced the creation of a new transportation task force for Near Southeast and Southwest, bringing together representatives of the government, residents, and developers to address the concerns of neighborhoods facing not only baseball, but also the coming influx of thousands of new workers and residents.
