On September 28, 2026, the Rockville Mayor and Council adopted a plan to bring the Shady Grove Metro station inside city limits. The plan covers about 66.4 acres on the west side of the station. When the Council introduced the effort in October 2023, it covered 107.9 acres. The east side faces Derwood and the county's Westside at Shady Grove development. It holds the station's two parking garages, and it was taken out of the plan.
Nothing is final yet. The Mayor and Council have scheduled a public hearing and decision for Monday, November 16, 2026, at 6:30 p.m. at Rockville City Hall, under case ANX2023-00147. The city's public record already explains how it chose which half to take. That reasoning matters to anyone weighing a home near the station, because it shows which side is set up for redevelopment and which side is expected to keep doing the transit work.
Where the Line Falls
The adopted boundary includes the Shady Grove Metro station, the Shady Grove Rail Yard, the surface parking lot west of the station, and an 11,200-square-foot building at 15910 Somerville Drive. Montgomery County leases that building from WMATA for a Kinder Care day care center. The plan also includes a strip of CSX railroad right-of-way between the two WMATA parcels. City staff kept it in so the boundary stays connected, which leaves room for Rockville to annex the east side later, "at the right time."
Most of the west-side acreage is rail yard, where Metro services and inspects its cars. Staff describe the developable part as mainly a surface lot of about 16 acres. A new bus rapid transit station, funded by the County, is also planned for the west side.
| West side | East side | |
|---|---|---|
| Proposed jurisdiction | City of Rockville, pending the Nov. 16 vote | Montgomery County |
| What sits there | Station, rail yard, ~16-acre surface lot, Kinder Care, planned BRT station | Two parking garages, a stream crossing the parcel |
| Proposed zoning | Rockville MXTD-235 | No change proposed |
| WMATA's current focus | Joint development study | Could likely accommodate transit and parking needs, per WMATA |
No existing homes are inside the boundary. Because the CSX land is a railroad right-of-way, staff noted there are no residents whose consent would be needed.
Why a City Would Want Land That Pays No Tax
WMATA property is tax-exempt. If Rockville annexes the station, it takes on municipal services there, police most of all, while collecting no property tax until something taxable gets built. In 2025, Rockville hired NewGen Strategies and Solutions to model the tradeoff. With no near-term taxable development, revenue would not fully cover the added police costs, which staff put at an average of nearly $1.3 million a year over the 25-year analysis period.
The May 2025 staff estimates make the gap concrete. Annexing the full site would have meant six more officers and about $1,015,000 in first-year police costs. The west side alone would mean four officers and about $676,700. The Planning Commission supported annexation but raised concerns about the cost of six officers. On May 12, 2025, the Mayor and Council decided not to move forward at that time "because of the high cost of police services."
So the upside has to be in what comes later. The May 2025 report listed what the city would gain: future mixed-use development under Rockville's Comprehensive Plan, more affordable housing, a larger tax base, simpler street ownership around the station, and the distinction of being the only municipality with three Red Line stations inside its limits: Twinbrook, Rockville, and Shady Grove. Councilmember Adam Van Grack, who moved to adopt the plan, wrote the next day that annexation would give Rockville "a stronger role in planning the land immediately surrounding this important transportation hub."
If the city carries costs now so it can control future development, the sensible move is to annex only the land that can be developed soon. That is what it did.
What Kept the East Side Out
When the plan came back in April 2026, staff recommended annexing only the west side. They called it "the best option to manage resources while capturing significant future redevelopment potential." The staff report listed the downsides of including the east side:
WMATA does not have any plans for any near-term development on the east side.
An existing stream bisects the property presenting environmental challenges for development.
There are two existing parking garages on the east side of the property, and the cost of relocating or redeveloping the structures may be significant.
Rockville's Department of Public Works also did a preliminary review of the east-side water mains and found possible limits on development there.
The garage problem has already come up once. In summer 2024, a private group asked WMATA about building a cricket stadium with mixed-use development on the east side. The project would have required tearing down an existing Metro garage and building a new one, and that cost was too high. WMATA is also generally required to bid out land competitively, and the proposal did not meet the exceptions to that rule.
WMATA Has Already Pointed to the Side That Keeps the Parking
Rockville's choice matches WMATA's own analysis. WMATA's 2021 Joint Development Feasibility Study found the Shady Grove site was not feasible to develop because replacing the transit facilities and other infrastructure would cost too much. WMATA reviewed the site again in spring and summer 2025. It said it would start studying the west side, "since there are minimal transit facilities at that location," and found that the east side "could likely accommodate all transit facilities and parking needs."
Here is the main point for Derwood. WMATA's analysis treats the Derwood side, where the two garages already stand, as the side that could take on the station's transit and parking needs, and both WMATA and the city are focusing redevelopment study on the west lot first. Keeping the station's parking on the Derwood side is what could free up the west lot.
WMATA's June 2025 Joint Development Work Plan moved Shady Grove from Group 4 to Group 3. Group 4 means "sites requiring additional long-term planning." Group 3 means "sites prioritized for joint development solicitation by 2032." A solicitation is when WMATA asks developers to bid on a site. That means a request for bids, not a groundbreaking.
Two Sides, Two Clocks
On the west side, the dates run through the annexation vote and then WMATA's process:
- November 16, 2026. Rockville holds its public hearing and decides on the annexation and the zoning map change.
- Five years after annexation. Under Maryland Local Government Article §4-416, the city cannot allow uses substantially different from the county's zoning, or density more than 50 percent above it, without the County's express approval.
- By 2032. WMATA aims to put the west-side property out for developer bids.
- FY 2031 and later. The city's April 2025 fiscal model tested construction starts in FY 2031, FY 2036, and FY 2041.
The proposed MXTD-235 zone allows buildings up to 235 feet by right, plus up to 100 more feet for affordable housing beyond the code minimum. The county's current zone allows 200 feet by right. The fiscal model assumed a full buildout of about 960 apartments and 50 townhomes, with 15 percent of residential space affordable. It was prepared in April 2025, before the boundary shrank, so treat those numbers as the city's earlier estimate rather than a plan. The adopted plan also says there is no current joint development application with WMATA.
On the county side, the work is already underway. The Housing Opportunities Commission and EYA broke ground on The Sage on May 1, 2026. It will have 413 mixed-income apartments next to Shady Grove Metro, 125 of them affordable, plus a new public library, with completion projected for June 2028. Montgomery County lists the library at 7,000 square feet. The last undeveloped parcel at Westside, Block U, is planned for 40 three-bedroom townhomes, five of them workforce units. The Planning Board approved it January 29, 2026, and the county expects closing by the end of 2026.
What "Near Shady Grove Metro" Means When You Are Comparing Homes
A listing that says "near Shady Grove Metro" can mean very different things depending on which side of the CSX tracks the home is on. On the Derwood side, most of what you will see in the next few years is already scheduled: The Sage under construction, Block U's townhomes, and the station's two garages, on the side WMATA says could likely accommodate the station's transit and parking needs. On the King Farm side, the big open question is the 16-acre surface lot. Who would plan it, how tall buildings could go, and when bids might go out all depend on the November vote and a WMATA process aimed at 2032.
Getting off the train is the same from either side. What changes is which government reviews the next project, and how far along that project is.
A Few Questions Buyers Ask
Would a Derwood home become part of Rockville? No. The adopted plan covers only WMATA and CSX land. Its site inventory lists transit, rail, parking, and the day care center, and no homes.
Does annexation change who runs the station or the water? WMATA would keep operating the station and WSSC would stay the water and sewer provider. Rockville would take over public safety and other municipal services, along with planning and zoning.
Could the east side be annexed later? Staff kept the CSX strip in the boundary so the city could pursue the east side once WMATA's development limits are clearer or a developer is identified.
Can I weigh in? Yes. Rockville accepts in-person, virtual, and written testimony for the November 16 hearing. Requests to speak and written comments are due by 10 a.m. that day.
