Four properties bought with Manteca Redevelopment Agency funds —including a 3.1-acre high-profile commercial parcel at Airport Way and Daniels Street — are destined to go on the auction block in 2014.The four parcels have a current estimated market value of $6.2 million.They are part of eight parcels the RDA owned when it was disbanded along with other redevelopment agencies statewide by the California Legislature. State law requires the city meet certain criteria for transferring the parcels to municipal ownership. Parcels that don’t meet such tests must be sold.
