The school's football and soccer competition fields, plus some practice fields, were severely damaged in March when someone drove a Jeep through them.
FVL posted a video on its Instagram account Friday showing sod being laid down on the soccer field.
FVL spokesperson David Payne says the extensive reconstruction project began in late summer. The soccer field is being sodded in hopes that it can be ready for girls soccer competition in the spring. Grass seed will be planted on the remaining fields.
The total damage was estimated at more than $250,000.
The school is offering a $10,000 reward for information leading to the arrest and prosecution of the vandal or vdanals.
Anyone with information is asked to call Appleton police at (920) 832-5500 or use the Report feature on the police department's smartphone app, which is available for both iPhone/iPad and Android devices.
