[47] This was in response to a public outcry of Mansfield losing an affordable housing litigation suit, and the then-committee voting several actively-farmed parcels as "redevelopment" to cover financial issues in the township, which started a warehousing boom in the community.

[48] Janice A. DiGiuseppe resigned in August 2015, citing personal reasons for leaving office after five years.
