Developers who hope to woo a federal agency to the Naylor Road Metro station in Prince George's County are scheduled to go before the county planning commission Thursday in the first of several steps before the project is given the green light.

Proposing 1.6 million square feet of office space on nearly 15 acres, Arlington developer Ironwood Realty Partners is building big in the hopes of snagging a federal tenant for the space. Naylor Road is one of four sites that county officials are highlighting as prime federal office space.

The Green Line station is also one of the 14 Maryland transit stations Gov. Martin O'Malley designated as a transit-oriented development priority last year.

Bob Abt, Ironwood's co-founder, said Naylor Road already has houses and apartments in the area but is lacking as a destination.

"Frankly, more jobs could stand to be located on that site and around the urban center and Naylor Station core area," he said. "That's what the county's core plan [calls for]."

Earlier this year, Prince George's lost out to Montgomery County when the General Services Administration announced it would keep more than 3,000 Department of Health and Human Services workers in Rockville, a decision County Executive Rushern Baker called a "major disappointment."

Other than a few locations such as the Census Bureau in Suitland and some Internal Revenue Service offices in New Carrollton, the county has traditionally been passed over by the feds because of its lack of major office buildings that could hold a government tenant.

Baker said Wednesday that, along with Naylor Road, county agencies are planning to submit proposals for Branch Avenue, New Carrollton and Largo Metro stations to the GSA in August.

"Bringing a major federal tenant will bring many of our residents who work outside the county closer to home," Baker said. "This kind of development will also increase our local commercial tax base, expand our employment base and attract retail to areas around transit stations."

The conceptual site plan also includes roughly 32,000 square feet of retail space and a seven-story parking garage holding up to 368 spaces. The project is proposed as a two-phase development, with the second phase depending on the future tenant's need for expansion.

A final vote by the planning board is expected in June.
