Drawings of the Westview Elementary School addition were shown off at the Sept. 14 Platteville School Board meeting.

The Westview addition — a gymnasium on the west side and a two-story addition on the east side — and improved entrances will accommodate first grade, moving from Neal Wilkins Early Learning Center, and fourth grade, moving from Platteville Middle School.

Platteville Public Schools received an AA-minus bond rating from Standard & Poors Thursday. School district business manager Art Beaulieu said the bond rating means that interest rates should be as projected.

The school district plans to sell $10 million in general obligation bonds Monday at 10 a.m., and the second set of $5 million in general obligation bonds around Feb. 1. The $10 million bonds will have an effective interest rate of 3.1 percent, and the $5 million bonds will have an effective interest rate of 1.9 percent.

The interest rates means that the school district’s annual debt service will decrease by almost $23,400, and the project will be paid off in 18 years instead of 20 years, Beaulieu said.
