"Beginning on Apr. 12, 2012 gates at the east and west end of the waterfront promenade (Riverwalk) at the Washington Navy Yard (WNY), will open for unlimited public access.

"The gates at both ends of the WNY Riverwalk will remain open for public access from dusk to dawn and will be open as a thoroughfare to facilitate access to the WNY and neighboring areas after sunset. There will be no loitering allowed between the hours of sunset and sunrise and the Riverwalk may close, without notice, to support WNY operations. [...]

"The Display Ship Barry, located along the WNY Riverwalk, will be open to the public with access directly from the Riverwalk during normal operating hours from 9 a.m. to 4 p.m. Monday through Friday and 10 a.m. to 5 p.m. on Saturday."

The release also quotes Naval Support Activity Washington commanding officer Cmdr. David Varner as saying that this is "supporting the community's desire to have a walkable riverfront."

The Navy Yard's portion of the Anacostia Riverwalk Trail runs from just next to the 11th Street Bridges down to the Yards Park.

(Note that April 12 is also the day of the Nats' home opener.)

UPDATE: For those who haven't been following along, I should note that it was last year that the Navy Yard first opened their promenade to limited public access, first just from 8 am to 5 pm Monday-Friday, then starting at 5:30 am, then to seven days a week until "official sunset."

First, a few new entries in the What's New Around the Ballpark? lineup:

* On Tap Magazine surveys the neighborhood with "The Hidden Gem That is the Capitol Riverfront." (Another jewelry metaphor to go with the Post's "Diamond in the Rough" piece from Sunday.)

* WJLA wandered around looking at the ballpark environs.

* The Post's Going Out Gurus blog checked out the Fairgrounds' sneak peek on Tuesday. (Though what's the deal with the photos that look like they were taken through a veil? Will this Instagram obsession never ebb?)

* WTOP runs down the options for arriving at the ballpark by water taxi. (American River Taxi, by the way, says that they are almost sold out for the April 12 home opener.)

Some other items:

* Two reports from MLB.com on the Wounded Warrior Amputee charity softball classic, played Tuesday after the Nats-Red Sox exhibition. The Warriors pounded their celebrity challengers 17-4.

* "DC Modern Luxury" magazine's Men's issue picks the Foundry Lofts as one of the city's "Best Bachelor Buildings." Go here, then click on the Best Bachelor Buildings subhed to get to page 62, then look at the bottom of the page. (As an aside, the write-up sounds even better if you imagine it being spoken by Stefon.)

* Or, if you like your tidbits a bit less glossy, Multihousing News has "Foundry Lofts Blazes Trail on DC Riverfront."

* Bluejacket gets a big write-up and cover photo in Beer Advocate magazine, though we don't get to read it online. You'll just have to make do with the Sept. 2011 batch of photos from inside the Boilermaker Shops the brewery has put up on their Facebook page.

* Nineteen "experts" have picked the Nationals to make the playoffs this year. No pressure!

* The 11th Street Recreation Bridge meeting happened while I was out of town, but here's Greater Greater Washington's write-up of it. But, before the meeting, WCP's Alex Baca posted four thoughts about the concept, with some items of concern worth noting (though "it is a cool idea!" is the first bullet point).

Since I've had a little bit of experience with census digging (I did a lot of my family's geneaology back in the early 2000s, before I began some other project that soon sucked up all my free time), I took a few minutes and found the links to the five enumeration districts that cover Near Southeast, along with the map that shows their locations.

So, if you live in Capitol Quarter, ED 204 covers you (from 2nd to 5th and Virginia to M). ED 203 goes east from 5th to 11th, while ED 205 includes all the blocks between 2nd and South Capitol north of M, for you Velocity/Onyx/CHT/Capitol Yards folks. ED 206 goes from M to the Waterfront and over to what's now the WASA site, while ED 207 covers the Navy Yard, which at that time ran from New Jersey Avenue to 11th. (It's actually funny how those boundaries from 72 years ago do a pretty good job of reflecting how the neighborhood's various sub-areas are still seen today.)

This was more than 10 years before the Cappers were built, but the neighborhood wasn't exactly a rich enclave. Plus, not many houses that were standing in 1940 remain in existence today, so only a few people will get the fun of seeing who actually lived in their house back then. But I thought one or two people might enjoy wandering through the many pages to get a feel for the people who lived in Near Southeast as World War II was looming. (You'll probably want to use the Questions Asked page to guide you across the columns. Note that the street name is written vertically in the first column, with the house number next. And the pages don't always perfectly follow the grid, so you may need to page through much of the ED to find the spot you're looking for. Plus, the image display is really cruddy right now, so using the option to download an entire ED and then browsing with the image viewer on your own computer might be preferable.)

Please post in the comments anything interesting you find--you'll make an old lady historian very happy.

(And I guess I might have to dig up the same information for earlier censuses. Not tonight.)

PS: If you don't live in one of these EDs, you can wander through the city map to find yours.

The "official" opening is planned for April 12, the day of the Nats home opener. I'm guessing that's when the market will actually open.

UPDATE: I visited the site about an hour ago, and they were still working hard, and the food trucks weren't on site yet. It looks like they'll open up the interior up at the Das Bullpen end of the street, but as I predicted, this is really just a chance to sell some food and drinks. The market portion of the project isn't anywhere in evidence yet.

But at least I took a bunch of photos of the perimeter for you to peek at!

Tickets for the Nats game also are good for the softball game, and a portion of the proceeds from tickets purchased here will go to the Wounded Warrior Amputee Softball Team. Celebrity participants include Mayor Gray, Jack Evans, Mike Isabella, Bryan Voltaggio, David Gregory, Darrell Green, Johnny Holliday, Luke Russert, and all other manner of local TV and radio personalitiies.

(Plus, the first 20,000 fans get a 2012 Schedule Magnet!)

If you're coming to the ballpark area for the first time since last season (or longer), be sure to check out my Visiting Nats Park page for information not only on getting to the ballpark, but on the various changes taking place nearby, as well as guides to some places that you need to check out, like the Yards Park and the Anacostia Riverwalk (easily accessible right across from the 1st Base Gate). The weather looks like it's going to be lovely.

If you're a resident, watch for some crowds and additional traffic, and of course beware of roving bands of marauders with Massachusetts accents.

The Nats' 2012 season officially begins on Thursday in Chicago versus the Cubs--they'll arrive back in Washington for their home opener on April 12, against the Cincinnati Reds. (If you're wanting to know when the team will be at the ballpark throughout the next six months, see my Events Calendar, where only the home games are entered.)

LATE UPDATE: A tweet says that the Fairgrounds is going to open tomorrow. I know nothing beyond that. (Though the market management site says "Opening April 12." Maybe they're both right.)

The Washington Post has a big A1 piece today by Marc Fisher looking at the area around Nationals Park, as well as the performance of the team and ballpark from an economic standpoint, in the four years since the ballpark opened.

For people who follow the neighborhood closely (i.e., JDLand readers), there's probably no new nuggets of information, but it's good as a "reset" piece if perhaps you haven't followed every twist and turn since the Nationals first came to DC in 2004.

There's also some additional detail and points of view from across the South Capitol DMZ, which of course I don't generally write about here. [Though, ugh, "Capitol Street"?]

Nats blogger William Yurasko does a good job breaking out the article's bullet points, if you want the Cliffs Notes version of the piece (since I'm not providing one!). But this part of the article probably stood out the most to me:

"The worries that [council member Jim] Graham, former mayor Adrian Fenty and other opponents shared about the ballpark becoming a financial dead weight seem to have been for naught.

"In the past three years, the ballpark fee, a tax levied on the city's 1,800 largest businesses, has brought in $85 million, double what the city had projected. Sales taxes at the stadium have lagged behind estimates because of lower attendance, but the city's overall take has been so strong that millions in excess collections have been used to balance the D.C. budget. The gusher of tax dollars will allow the District to pay off the 30-year stadium bonds as much as 12 years early, which will let the city scrap the business tax sooner than planned[.]"

If you want to know more about what's changed just within the past few months around the stadium, my new Visiting Nats Park page has a "What's New" rundown, along with much more information and photos from the stadium's construction and big events. Or you can click on the map at above right on the home page (or visit my full project map) to dig in more deeply to what's happened not only since the ballpark opened but going back to 2003.

[Full disclosure: while I worked on the big map graphic that accompanies the article, I had zero to do with the article itself--though I think my web site helped out!]

It's a real milestone in the redevelopment of Near Southeast to report that the entire stock of townhouses for sale at Capitol Quarter has now sold out.

The first reservations for units were taken in October 2006 (remember the people camping out?), construction began in summer 2008, Phase 1 finished construction and Phase 2 reservations began in 2010, and now, with construction underway on the last group of houses on L between 3rd and 4th, the finish line for the project is not far away.

The development has been the third phase of the Hope VI redevelopment of the old Capper/Carrollsburg public housing project, replacing the old housing with nearly seven blocks of brightly painted rowhouses, containing not only 130ish market-rate townhouses (a few of which have broken the $1 million barrier) but also 90ish special workforce-rate houses for smaller incomes, in addition to nearly 90 subsidized rental units.

Those units, combined with the 300 built at Capper Seniors #1 and 400 M Street, mean that more than half of the 700 units in the old Capper have now been replaced. The rest are slated to come in five mixed-income apartment buildings, located on the west side of 3rd Street, on L Street south of the Marine Bachelor Enlisted Quarters, and on the DPW/trash transfer station site at New Jersey and K. No timelines have been announced for any of the remaining buildings, but you can see on my main Capper page a map with estimated unit counts for each.

I've taken a lot (a LOT) of photos of the Capper footprint since 2003: my Capitol Quarter Phase 2 and Phase 1 pages give a good overview, or you can just pick a spot along 3rd, 4th, or 5th Streets in my Photo Archive and take a look.

I had an opportunity on Monday to make a trip to Viera for my first-ever Spring Training game, to see the Nationals beat the Houston Astros, 7-4. While sitting in the warm Florida sun for a few hours watching baseball was the top priority, I did arrive with camera in hand, and so couldn't pass up the opportunity to take a bunch of pictures of the Nats' other stadium.

So, here are two photo galleries that might be of interest: looking around Space Coast Stadium, and action photos from the Nats-Astros game.

The Nats will be back at their real ballpark one week from today, for an exhibition game on April 3 against the Boston Red Sox. The home opener is now just a smidge over two weeks away, on April 12 against the Cincinnati Reds.

* Don't forget that the public meeting about the possible recreational re-use of the old outbound 11th Street Bridge span is on Wednesday, March 28, at 6:30 pm.

* Justin's Cafe has now posted the information on its April 14 block party, both on Facebook and its new JustinsCafeEvents.com web site. It will run from 11 am to 9 pm, offering a line-up of local craft brews (including "beer trucks" from Port City Brewery and DC Brau), and 106.7 The Fan FM will be broadcasting from there. "All ages welcomed, 21 and over to drink." Money is also being raised for free youth baseball and softball programs through the DC Grays and S.M.A.R.T. Camps and Clinics. (The Nats play the Reds at 4:05 pm that day.)

* On April 1 (well, April 2, technically), the Union Station-Navy Yard Circulator bus starts its summer hours, running from 6 am to 9 pm weekdays and 7 am to 9 pm Saturdays, with extended service on Nationals game days.

* The Southwester reports that there's a Neighborhood Night at Nationals Park on Thursday, April 19. "The team will honor the vibrant spirit of the neighborhood by featuring local residents in various pregame activities, including throwing out the first pitch, delivering the lineup card and greeting the players as they take their positions on the field." Near Southeast and Southwest residents can also get discounted tickets to games throughout the season, but I'll make you follow the link to find out about that!

* The Earth Conservations Corps will be leading volunteers in a cleanup of the wetlands at Diamond Teague Park on April 21, from 9 am to noon, as part of the Anacostia Watershed Society's Earth Day events. (They do want volunteers to register/RSVP in order to participate.)

* A bit farther down the pike, the Kennedy Center is presenting "Look Both Ways: Street Arts Across America," a week-long festival showcasing all manner of free performances and events from May 6-12. One of the May 6 kick-off events will be from 11:30 am to 1:30 pm at Nationals Park and the Fairgrounds (old Bullpen) on Half Street, and the closing event on May 12 from noon to 6 pm will be at the Yards Park.

* Shipping containers have been arriving at the Fairgrounds (Bullpen) site. (They say there's going to be a "preview" event on March 30--looks like a lot of work to do in eight days. But the real opening is supposed to be in time for the Nats' season opener on April 12.)

* Greenery is arriving at 200 I/225 Virginia, and the sidewalks are done. Apparently the fences will be moved back sometime next week to keep the building perimeter secure but to allow the sidewalks to be used. (In other words, the "street sidewalk" will finally disappear.) There should also be repaving and crosswalk striping around the site coming in early April.

Without Pictures:

* Framing is racing along on the stretch of Capitol Quarter townhomes on 3rd south of L.

* Curbs are going in on 2nd Place next to Canal Park and the pavilion.

* The cherry trees in the Center Field Plaza at Nats Park are budding, but don't look on the verge of popping yet. Perhaps they can hold on until April 3.

Elsewhere:

* Mark Batterson says the demolition of the Miles Glass building and the garage next door on Virginia Avenue will happen next week.

* Yesterday we were talking about the possibility of a little BOOM, but here's what might happen 'round these parts if there's a really BIG BOOM.

* The Post writes about the neighborhood as part of the big Mega RealEstate focus on walkable communities, and keys in on the fact that the area has a number of different names. (For the record, it's not like I made up "Near Southeast"--I was just following the city's lead.) Within a few hours, though, Greater Greater Washington may have solved the problem by pointing us to the area's late-19th-century moniker: "Bloodfield." Wouldn't that work great for ballpark headlines? ("Phillies Dismembered at Bloodfield.")

Anything else folks are seeing?

One reader sent me both videos and a series of iPhone photos showing the activity, but it was DCIst that got the money shot: a photo clearly showing a big ole' UXO (oh, heck, let's have fun and call it a bomb). This site is of course part of the old Navy Yard footprint, where all manner of exploding items were manufactured for many years.

Since no one's reported any big BOOMs in the intervening time, the clean-up must have proceeded according to plan. The question is, will there be any more surprises once digging resumes?

UPDATE: Here's WJLA's report on the day's festivities, and then DCist unearthed these two videos of the gun factory from 1952.

UPDATE II: While we're all enjoying being a bit flip about all of this, it is of course a serious business to be doing this excavation with such items laying around. Forest City tells me that the work is being done in accordance with guidelines from the Army's Explosive Ordnance Division, and that indeed over the past several weeks sitework has needed to be stopped temporarily because of the unearthing of "munitions debris." Each time, the police department's bomb squad is called in, who then determine whether the EOD folks from Ft. Belvoir should be called in, as they were today.

Forest City also says that it's anticipated that most buried artifacts and debris are found within the first 10 to 15 feet of soil when excavation, so once they get past that level, they expect the finds will trail off. And, it's not just munitions being found--foundations of several homes that were on site prior to the lot being used by the Navy have been found, as well as a Civil War-era cannon.

But the company does want to emphasize that "public safety and the safety of the site workers are paramount for Forest City, so we will continue to strictly abide by the established practices and involve the qualified technicians whenever and as soon as necessary." This includes having a former Navy munitions expert on site at all times as a "spotter," and using a two-part method when excavating, scooping the dirt from the hole in small quantities and spreading it out to be looked at and cleared before it's then scooped into a truck for removal from the site.

Whether this will impact the timeline for 1212 4th's construction depends on how many stoppages there end up being.

This means a lot of people will be returning to the Near Capitol Ballpark River Yards neighborhood for the first time since last summer, or might even be venturing in for the first time ever thanks to the buzz around the team's potential. So I've created a new page: Visiting Nationals Park, which brings together links and information both about the ballpark itself and what's available and interesting outside the stadium.

It includes a What's New and Notable Since Last Season page, as well as a Google Map showing the nearby food and drink options (both currently open and the ones announced to be on the way). And there's links to my new Anacostia Riverwalk page and Yards Park and Navy Yard pages for people looking for things to do (that don't involve food!) before or after the games.

As for the ballpark itself, there's my map of official and "cash" parking lots, a "Getting There" guide, and of course all of my photos of the stadium's construction and milestones.

I'm sure it'll be updated with more items as Opening Day approaches, but I figured I'd go ahead and get it out there now (especially to help everyone in the media getting ready to write their annual What Is/Isn't Happening Near Nats Park pieces!).

If you missed the hullabaloo, the city is looking at the notion of reusing the structure of the soon-to-be-abandoned downstream/outbound 11th Street Bridge as a recreation destination, linking both sides of the Anacostia River "in a unique and dramatic way."

And there's also now a page on the OP web site about the project, noting that no decisions have been made or even committted to on the project. The page also makes sure to mention that "actually seeing this project realized will be very ambitious and challenging." A design competition will be held later this year, and apparently the process will "involve local youth in generating ideas." And, as Lydia DePillis noted, there will have to be a "significant level of partnership with the private and non-profit sectors" in order for this to work.

The meeting will be held in the DCRA office space at 1100 4th St., SW. Bring your ideas!

* More Demolitions Coming: Raze permits have now been approved for the Miles Glass building at 8th and Virginia and its next-door neighbor, the closed auto repair shop at 7th and K. National Community Church, which owns the lots and others on the same block, said back in January that a temporary parking lot and "community green space" will be coming to the site while the church continues to work on its final plans for the site, which in the past have been described as being a combination of coffee house, performance space, and church offices.

* Yup, Navy Yard-Ballpark. The new Metro subway map is out, and confirms that Navy Yard-Ballpark is official.

* Bike to Work: May 18 is DC's Bike to Work Day. One of the pit stops is the Yards Park, from 7 to 9 am, and you get a t-shirt if you register and then stop at your designated pit stop.

* Bridge Recreation: If the notion of the "11th Street Recreation Bridge" captured your fancy, you can see some additional stories on the idea by Lydia DePillis, BeyondDC, and WJLA. DePillis notes that the city isn't intending on paying for this entire thing itself, and a decision needs to be made by May whether or not the new 11th Street Local bridge will have the bulb-out viewpoints built (they'd be unnecessary if the current downstream bridge was being kept). WJLA, on the other hand, mentions that "some" are concerned it "could become a hotbed for crime"--which led to a fun Twitter back-and-forth that devolved into using the new bridge for a Jason Bourne/James Bond-type chase sequence.

* Mobile 'Hood: The Capitol Riverfront BID has launched a mobile version of its web site, which uses your phone's GPS to give you information on food, developments, and events near your location.

And, of course, if you want to know what your current location looked like before all the changes started happening, you can go to my mobile site (m.jdland.com) or jdland.com/here on your phone and you'll get my oldest photos looking in each direction from the corner nearest to where you're standing. (Read more about how that works.)

* Fairgrounds: DCMud looks at the plans for the Half Street Fairgrounds (which I broke the news of back in February), with a few neat new renderings. And then the piece drops a mention at the very end that "DCRE Real Estate" is handling the retail leasing for the project--that's DCMud's company, and the writer of the blog post is also the agent handling the leasing. (Just in case you like to be aware of those sorts of things when getting your news.) In the meantime, a few shipping containers were spotted on the site last week.

* Across the Way: A 5,000-seat concert hall is being designed for the Southwest Waterfront. (If you haven't been keeping up with the plans for The Wharf, SWill can help.) And the de-skinning of the old EPA buildings, visible from parts of Near Southeast, is part of their rehabilitation into the Sky House apartments.

To help get to know the candidates, the Ward 6 Democrats are hosting an At-Large Candidates Forum tomorrow, Tuesday, March 20, from 7 to 8:30 pm at Brent Elementary School at 301 North Carolina Ave, SE. The forum will be moderated by WTOP's Mark Segraves, and the event is free and open to the public.

Running are Vincent Orange (the current seat holder), E. Gail Anderson Holness, Peter Shapiro, and Sekou Biddle (all Democrats), Mary Brooks Beatty (Republican), and G. Lee Aikin and Ann C. Wilcox (Green Party).

Early voting for all races starts today (March 19) at One Judiciary Square. From March 24 to March 31, early voting expands to seven additional locations, including the King Greenleaf Rec Center at 201 N St., SW. For more information about the election, go to the Board of Elections web site.

The brewery also now has a web site, a Twitter feed, and a Facebook page. And an "Established 2013" tagline, so that's another confirmation that they don't look to be opened before the end of this year.

The brewery will be located on the eastern end of the Boilermaker Shops building, fronting 4th Street SE.

"Exercise SOLID CURTAIN-CITADEL SHIELD 2012 will be conducted on naval bases and installations throughout the National Capital Region from March 19-24, 2012.

"This annual exercise is designed to enhance the training and readiness of Navy Security Forces to respond to threats to installations and units. Exercise SOLID CURTAIN-CITADEL SHIELD 2012 is not in response to any specific threat, but is a regularly-scheduled exercise.

"Measures have been taken to minimize disruptions to normal base and station operations, but there may be times when the exercise causes increased traffic around bases or delays in base access. Area residents may also see increased security activity associated with the exercise."

[And yes, I'm making a point with that headline.]

* Justin's Cafe is looking to have a block party on Saturday, April 14 (when the Nats and the Reds play at 4:05 pm), and ANC 6D has supported the request to close 1st Street between K and L. (Thanks to SWill for, once again, picking up my slack.) Still probably some bureaucratic hoops to jump through before all is confirmed. This was moved from Opening Day so it would be on a weekend, Will says,

* Looks like DPW's trucks have departed a couple weeks earlier than expected from the agency's longtime home at New Jersey and K, although all the lights may not be turned out just yet. Demolition is in the cards, though some environmental abatement has to happen first.

* New striping and bike lanes were installed Monday on I Street SE between South Capitol and New Jersey.

* Start starving yourself now to prepare for the Red Porch's eight-pound "StrasBurger."

* Photographic evidence of fences down at the old Bullpen, clearing the way for Fairgrounds.

* Only four houses left for sale at Capitol Quarter.

* Bank of America is now building out its new space in the ground floor of 55 M south of the Metro entrance, informed sources say. (They're closing their Southwest location in June.)

* Could DC United be setting up shop just a few blocks up Potomac Avenue from Nationals Park?

* Near Southeast gets off relatively easy in this Sunday's National Marathon Street Closure Sweepstakes (just South Capitol south of L, and the Douglass Bridge).

Anything else going on these days? Besides that sandwich shop opening?

UPDATE: Let's add the elephant parade! Starting tonight at 8 pm, on the southern edge of Garfield Park at the train tracks where Virginia crosses under New Jersey, says WTOP.

UPDATE II: And, from the Hill is Home, a Q&A with ANC commissioner David Garber.

UPDATE III: I sent a lackey down to Potbelly to get a few opening-day shots. Hope he's not expecting to get reimbursed for his lunch.

It will be open from 10 am to 7 pm seven days a week, and, if you're unfamilar with Potbelly's menu, you still have a little time left to bone up.

It's in the ground floor of the Foundry Lofts building, about two blocks east of Nationals Park, and one block south of M Street behind the US Department of Transportation headquarters. It's also the first "chain" food establishment to open in Near Southeast since Starbucks opened at USDOT in fall 2007. (Five Guys opened on 2nd Street waaaaaay back in May 2005.)
