Superintendent Patrick Murphy

Superintendent Patrick Murphy makes apresentation on secondary-school capacity to School Board members in 2014, as John Chadwick, who oversees planning and construction for Arlington Public Schools, looks on.

Arlington School Board members on Aug. 17 will consider a staff proposal to purchase a single-family home adjacent to Glebe Elementary School, which would be torn down and the lot used for emergency-vehicle access to the elementary school.

School-system staff has proposed purchasing the home at 1721 North Culpeper St. for $525,000, while setting aside an additional $50,000 for closing and demolition costs.

Currently, the only vehicular access to the school is via an easement from Capital Life Church, which funnels traffic to and from North Glebe Road.

If the home is purchased, the land would be used only for access by emergency vehicles, school officials said.

The prospective purchase drew some pushback during a public-comment session, in part because the school system plans on spending nearly $125,000 more for the property than it sold for this past January, when a Falls Church-based investment firm purchased it for $403,655, according to county-government records.

John Chadwick, the school system’s assistant superintendent for facilities, said the purchase made sense, since the school system has no vehicular access outside the church easement.

“It would not work as a main entrance . . . but it does allow us that emergency access, and pedestrian access, as well,” Chadwick said of the proposal.

Funding would come from the school system’s capital-reserve fund.
