CAPITAL BUDGET ADOPTED -- The board adopted a $206.8 million capital improvement program for fiscal years 1988-1993 that includes $20 million to be sought in referendum for a new jail.

Arlington voters will be asked to approve a $20 million bond issue for a new county detention center next fall. If funding is approved, construction could begin during 1989.

Arlington's current jail, located in the Courthouse complex, was designed to hold 164 inmates, but usually holds about 200 inmates at a time, according to county officials. If approved, the new jail would have 396 beds and would be built on the site of the county-owned Holmes building across the street from the Courthouse.

The jail project is part of $56.4 million proposed in the budget for government buildings. The six-year proposal also calls for spending $64.7 million for water and sewers, including upgrading and expanding the waste water treatment plant.

While the board approved the budget in concept on Saturday, it only approved funds for the program's first fiscal year.

The board approved $16.6 million to be spent on capital projects during fiscal 1988, which began this week.

The six-year budget, which anticipates bond referendums in 1988, 1990 and 1992, calls for $105.2 million in pay-as-you-go funds from taxes and utility fees and $101.6 million from bonds.

The budget proposes spending $20.2 million for road improvements, including $7.4 million to widen a three-quarter mile stretch of North Glebe Road from I-66 to North Randolph Street and $6.6 million to extend North Quincy Street from Wilson Boulevard to North Glebe Road.

The fiscal plan also includes $12 million for school buildings, $6.6 million for park and open space acquisition, $2.5 million for park and recreation center improvements and $4.8 million for the county's neighborhood conservation program.
