Data Centers to Replace Office Buildings on Sunrise Valley Drive

Data centers with a fenced perimeter are inching closer to approval at Sunrise Technology Park, a 21-acre office park with four existing buildings slated for redevelopment. The Fairfax County Planning Commission approved the project by CoreSite Realty Corp. on June 28.

The proposal is part of a move by CoreSite to expand its footprint in Reston. The company selected the location on the south side of Sunrise Valley Drive in order to ensure the operation was near enterprises in Reston. The property was purchased for $60 million from Brookfield Office Properties in 2016.

“They had a choice of where they wanted to be,” said David Gill of McGuireWoods and the developer’s representative, adding that CoreSite was willing to “roll up their sleeves and a pay a premium to adaptively reuse [the] office park.”

The development is divided into four phases, one of which is currently in progress. When the first phase is complete, two existing buildings on the southern half of the property will be reconstructed and expanded with about 291,000 square feet of development. Two buildings will be demolished on the southeastern edge of the property to make way for a three-story building with 240,000 square feet in the second phase.

During phase three, one building and associated parking in the center of the property will give way to a three-story data center and another building. The fourth and final phase on the northern edge of the project will involve the demolition of existing buildings to make way for a three-story data center with 172,000 square feet. The number of stories on the buildings may vary, but will not exceed three stories.

Gill noted that the development will reduce traffic by 60 percent both during peak traffic hours and an overall reduction in trips. The data centers are expected to house a maximum of 45 employees. The development will also remove 700 parking spaces on the largely vacant site, Gill said.

However, planning officials said they were concerned buildings in phase two do not sufficiently meet environmental efficiency standards, namely LEED certification.

Gill noted CoreSite is using technologies like a cistern that uses rainwater to cool servers. CoreSite plans to address the county’s concerns about LEED certification and energy efficiency before the Fairfax County Board of Supervisor’s vote on the project, Gill said.

During the commission’s public hearing, Brian Carpenter, a resident from a nearby residential zone, said he wanted to ensure security cameras on the property would not compromise the privacy of nearby homes. The issue will be discussed with the developer.

CoreSite Will Spend $60 Million for Reston Data Center Space

12369 Sunrise Technology ParkData center provider CoreSite has entered into a deal to purchase four office buildings on Sunrise Valley Drive near the Fairfax County Parkway.

CoreSite announced last week it will spend $60 million to acquire the 22-acre Sunrise Technology Park in the 12300 block of Sunrise Valley Drive, the Washington Business Journal reported.

Sunrise Technology Park, currently owned by Brookfield Office Properties, is a complex of four low-rise office buildings, totaling 315,000 square feet.

CoreSite says it could build more than 660,000 square feet of new data center capacity across the parcel. It currently has about 400,000 square feet of space in Reston.

CoreSite said in a release it expects to spend $90 million more on the first phase of the new development. Initial work will include the conversion of one 48,000-square-foot building into a data center, and the construction of two, 92,000-square-foot buildings — one data center shell, and one structure to house “centralized infrastructure.”

After the deal closes in December, CoreSite expects to start construction during summer 2017. It estimates it may spend as much as $500 million building out the site over many years and multiple phases.

“This planned expansion to our Reston campus is designed to meaningfully scale our colocation offering in the important Northern Virginia market, leveraging off of the installed network-and-cloud capabilities already deployed at the campus,” CoreSite president and CEO Tom Ray said in a statement.
