CAPITAL IMPROVEMENT BUDGET -- Alexandria School Superintendent Paul W. Masem presented a proposed $2 million capital improvement budget for 1988-89 for Alexandria's 15 public schools -- down $119,300 from the current capital budget.

The main reason for the decrease is the postponement of a proposed $450,000 project to build additional classrooms at Cora Kelly Magnet School. Masem said the school administration should first conduct a long-range plan for the magnet school based on demographic changes. He proposed the classroom project be included in the 1989-90 capital budget.

About $1 million of the proposed budget is allocated for the continuing building modernization program, which includes upgrading school mechanical and electrical systems. This year, $675,000 is being spent for modernization.

The budget also proposes $424,000 for the continuing school renovation program, down from $585,000 this school year. Renovation means restoring electrical and other mechanical systems rather than upgrading them with newer systems. City school buildings are an average 36 years old.

The school administration is also proposing to spend $292,000 on improvements to school heating, ventilating and air-conditioning (HVAC) systems, down from $530,000 in this school fiscal year.

Other projects in the proposed budget include $44,000 for handicapped accessibility improvements at Patrick Henry and Jefferson-Houston elementary schools, $100,000 to replace the boiler at Maury Elementary School, $100,000 to replace the roof of Mount Vernon Elementary School, $160,000 to replace windows at George Washington Junior High School, $180,000 for heating and electrical improvements at Hammond Junior High School and $500,000 for improvements at T.C. Williams High School -- including $40,000 for stadium bleacher improvements and $100,000 for new windows.

The School Board will hold a public hearing on the proposed capital budget at 7:30 p.m. Oct. 7 in the board room of the Howard Administration Building, 3801 W. Braddock Rd. The board is scheduled to vote on the budget at its Oct. 22 meeting. The City Council will act on both the school operating and capital improvement budgets when it approves the final city budget next May.
