TEMPLE FOUNDATION Inc., a church-sponsored organization that runs two life-care facilities in northern Virginia, has been released from bankruptcy after the residents of both facilities agreed to changes in their contracts that increase fees they will pay to keep the foundation afloat.

"We've had 100 percent success getting agreement from everybody," said the foundation's president, Preston Caruthers. "We are out of bankruptcy and now in the process of putting both homes on a sound financial basis, which these agreements enable us to do."

Temple, a nonprofit corporation that opened The Washington House in Alexandria 12 years ago and The Virginian in Fairfax four years ago, filed for Chapter 11 bankruptcy last February after inflation and the rising cost of medical care brought the foundation close to insolvency.

As life-care facilities, the two residences combine independent living for elderly people with support facilities and nursing home rooms in case the residents become too old to care for themselves. Most of the residents had paid large endowments upon admittance, and also paid a monthly apartment fee. Residents agreed to substantial rises in infirmary fees and more modest increases in some apartment fees.

JOHNS HOPKINS University will ask the D.C. Zoning Commission to reconsider its rejection of university plans for an addition to the Hopkins School for Advanced International Studies at 1740 Mass. Ave. NW. The commission denied the SAIS application for a planned unit development in August, saying the proposal would not provide substantial amenities to the community, as required by the D.C. zoning code.

The school wanted to build an eight-story addition on the rear of its present structure, which officials say is extremely overcrowded. If the commission agrees to reconsider the application, SAIS will reduce the planned height of the addition from eight stories to seven, a spokesman said.

In rejecting the school's proposal last August, zoning commission members said the planned addition was too big and the amenities offered, including access to the institution's library for scholars from the neighborhood and a public terrace, were not sufficient to meet code requirements.
