* DECLARATION DECLARING: A press release from Grosvenor says that Declaration will be opening at F1rst, in mid-March, as the building's first full-service dining option. "This new location will be double the size of its counterpart in [Shaw] and will offer pizza and Philadelphia-oriented menu items, including some ballpark staples." The release also says that Barre3 will open in spring late summer or fall [error in press release, I'm told]. With these openings, only one retail space at F1rst remains unleased.

* BARRACKS DECIDING: The Record of Decision and Final EIS for the new Bachelor Enlisted Quarters have been published, ending a study phase that feels like it began in 1936. The chosen site plan is to build the new BEQ immediately to the north of the barracks at 7th and L, SE (Building 25), which will spell doom for either some or all of the athletic field (it's been so long, I don't remember anymore). Read the MBEIS web site for actual details that aren't from memory.

* SOUTH CAPITOL PROJECTING: DDOT announced some temporary lane closures this week in multiple locations "for pre-construction work associated with the South Capitol Street Corridor Project and the new Frederick Douglass Memorial Bridge project." I believe this is the first mention of "pre-construction work" for these projects--or at least they are since the design-build contract was awarded.

* PEPCO DISRUPTING: ANC 6D07 Commissioner Fascett reports that PEPCO will be digging up portions M Street SE between 1st and 6th and 1st south of M to install underground pipes and then cables during February and March. Watch for daytime traffic disruptions weekdays and Saturdays.

* WILLOW VALENTINING: If you are in a red-heart mood on Saturday (Feb. 10), retail boutique Willow is having a Valentine's Day party, from 11 am to 7 pm. There will be valentine-making, cupcakes, a photo booth, and more. (Strangely, the valentines give out all look like this.) Willow is in the ground floor of Arris, on Water Street across from District Winery, just north of the Yards Park.

In other tidbits I've been meaning to pass along:

* ZAC BROWN: Normally Nats Park hosts a big concert during the All-Star break, but the stadium will be otherwise occupied during that stretch, and so this summer's big show, the Zac Brown Band, will be on July 27. Tickets are on sale now. UPDATE: And I've been reminded in the comments that this is actually the second of the big summer shows, with the Eagles and James Taylor playing the night before.

* CHLOE: The Post's Tom Sietsema liked what he saw at Chloe, calling himself "bewitched" with the debut menu, and that "right out of the gate, Chloe feels like a keeper."

* TUNNEL: The next "Coffee with Chuck" status meeting on the Virginia Avenue Tunnel is on Wednesday, Jan. 24, from 8 to 9 am at the CSX office at 861 New Jersey Ave., SE. There is lots of work in the 300 block of Virginia Avenue these days to turn it back into an actual street, with the beginnings of curbs and sidewalks and preparations for drains and streetlights, as well as working toward returning the entrance to the Capitol Quarter driveway to its original path from Virginia.

* PSA 106: This month's PSA-106 meeting is Tuesday, Jan. 23, at 7 pm at the Capper Community Center at 5th and K, SE. MPD holds these meetings to discuss residents' concerns and questions about public safety issues.

I took a bunch of pictures this weekend, but will write about that when I recover.

This will be the fifth DC location for the chain, which "mixes athleticism, grace, and the latest innovations designed to balance the body," according to its web site.

The studio is expected to open early fall-ish 2018, and joins Taylor Gourmet, Chop't, Chipotle, Roti, Rasa Indian Grill, the aforementioned Solidcore, and the still-to-come Declaration.

{And no, it's not your eyes, the photo is blurry. Sigh.}

I don't know a timetable, I know nothing more than this sign, but at least this should settle people's worries a bit.

We now return to our holiday weekend, already in progress.

Not only will there be treats and drinks and lots of stuff to buy, but "every guest will receive a complimentary Willow-designed Navy Yard shot glass."

The party will run from 5 to 8 pm.

The official web site for this location allows reservations for upcoming classes, and also has some grand opening deals available ($4 for your first class, plus 10-pack and 1-year membership specials).

Regrettably, I did not get a chance to swing by for an updated photo before posting this, so here's my most recent shot of the Solidcore location, located next to soon-to-be-Rasa on 1st Street SE between M and N. (Official street address is 1245 1st St. SE.)

And now to a way-too-long pile of tidbits:

* PLAYOFFS: I doubt anyone at this point needs to tell me that the first of what will hopefully be numerous playoff games this October at Nats Park is tonight (Friday), when Game 1 vs the Cubs starts at 7:31 pm. They'll play again tomorrow at 5:38pm, and would return on Thursday Oct. 12 for the fifth game of the series, if necessary. Here's a rundown from the BID of playoff-related festivities and deals that might be of interest.

* WILLOW: I have been remiss in not passing along that DC-based clothing and gift shop Willow is going to be opening a second location in the ground floor of Arris, at 4th and Tingey in the Yards. As described in the BID newsletter, "The store brand adds a distinctive local twist with DC neighborhood-inspired gifts and clothes designed in-house by members of the Willow team."

* DOCKSIDE?: I have not confirmed this personally, but a reader reports being told by workers putting out tables on Thursday that the new Yards Park boardwalk kiosk outlet of Osteria Morini is expected to open this evening. UPDATE: Reader now says that no, it's Due South Dockside. But that's what I get for not reporting it out myself. {hangs head in shame}

* BYE BYE 37 L: Photographic evidence on Twitter of the demolition of the Empire/DC Flyer Cab company building, which is making way for a new residential building. It becomes the 175th entry in my Demolished Buildings Gallery (up a spot from its brief designation as #174, after a reader pointed out that I had neglected to add, of all things, the McDonald's, though I will give myself a break on that one, given the maelstrom in my life at the time).

* THIRD STREET CLOSURE UPDATE: Flashing signage north of 3rd and Virginia says that the four-month-ish-southbound closure is now scheduled to begin Oct. 11. (After the first two games of the playoffs, I might add.) I saw from the freeway yesterday that the huge reinforcing beams (more like tubes) that were installed across the footprint of the two tunnels are being removed between 2nd and 3rd Streets, and there's even now some small square footage where both tunnels are covered with dirt. (UPDATE: The sign was changed this morning to read "On or About Oct. 10," and now the latest VAT newsletter says "as soon as Oct. 9.")

* GARRETT TEA LEAVES: The building permits have been approved, and construction trailers arrived within the past few days at the staging lot on the former trash transfer site at 2nd and K, and so signs are pointing to work getting underway on The Garrett, the last of WC Smith's "Collective" troika. Joining siblings Park Chelsea and not-yet-open-but-newly-landscaped Agora, the Garrett will have about 375 rental units, and ground-floor retail. (No, I don't know when Whole Foods is opening.)

* PARC RIVERSIDE PHASE II: A reader who lives at Velocity says that management informed residents that work is expected to resume Any Second Now (or maybe already has) on the excavation for what will be the second phase of the Parc Riverside residential project, at Half and K.

* BOWER FLOOR PLANS: If you have been desperately awaiting the condo project known as the Bower to start selling, well, that hasn't happened yet, but floor plans are finally available on their web site. (h/t RMP)

* DACHA: Way back in March it was learned that Shaw's popular beer garden Dacha will be coming to Dock 79, and signage now confirms that. It will occupy the space along the riverwalk on the building's southwest corner--closest to Bardo, for some hot beer garden-on-beer garden action.

* PUNCH BOWL SOCIAL: Less way back, in May, it was announced that "eatertainment" venue Punch Bowl Social will occupy 24,000 square feet on two floors at 1250 Half Street, aka the residential building that will soon fill the Half Street Hole directly north of Nats Park. To quote from the press release, Punch Bowl "has made a name for itself with its remarkably balanced execution of the eat, drink, play concept, pairing a Chef Hugh Acheson designed, southern inspired scratch-made menu and craft beverage program with social activities including pinball, skee-ball, karaoke, vintage video games, bocce, bowling, and more."

* STEADFAST SUPPLY: The "unique marketplace that connects brands with consumers" has opened anew, now at the Boilermaker Shops on Tingey Street in the space formerly occupied by Hugh & Crye. Hours are 12-6 pm Tuesdays-Sundays. (Alas, I got my photo about 24 hours too soon, so it's out of date already, but "progress, not perfection" is the current JDLand motto.)

* OTHER COMING SOONS: While wandering a week ago, I procured photographic evidence of the work going on at Roti at F1rst on 1st Street, as well as some of the recent Coming Soon window signage that I don't think I have posted, for Cava Grill next door to Shake Shack at the Homewood Suites at 50 M, and both the Juice Laundry and Cosmopolitan Nail Salon at Arris. (I didn't get Eighteen Eight Salon because I know I posted that at some point. Not sure if I missed window signage for Shilling Canning Company and/or Chloe, though?)

There. Now I feel a little better.

It will offer full-service nail and waxing treatments, with free WiFi, refreshments, and "individual guest tables to listen to music or watch a movie during appointments."

The new nail salon will join Arris's already-open Philz Coffee and previously-announced-as-coming-in-2017 tenants Conte's Bike Shop and the Juice Laundry.

This would be the second DC opening for the company, joining its 14th St. NW location (along with one in Bethesda and two others in Maryland).

In addition to haircuts, 18|8 offers face, scalp, and nail treatments, shaves, waxing, and coloring; there are also grooming party packages for when you guys want to get with your buddies and get all gussied up.

It's Tingey Street's second grooming outlet, joining the Bang Salon one block to the east. (Too bad Unleashed doesn't offer grooming, otherwise there'd be a Tingey trifecta.)

No official word on when it will open, so don't let your hair get too long while waiting.

Meanwhile, one block to the south, the new District Winery building is getting its face on.

(h/t to reader RMP for the 18|8 sighting)
