A proposed land deal will allow Rusnak Mercedes-Benz dealership to expand and Rod's Grill will not have to move. The Arcadia Redevelopment Agency has acquired the Dahlgren lot on Santa Clara Street, the last parcel of a 2-acre site it intends to sell to Rusnak. This sale would enable Rusnak to expand from 4 to 6 acres. A public hearing is scheduled for April 19. In addition to the recently acquired Dahlgren property, the current proposed site also includes the former Church of Arcadia on Morlan Place and a commercial strip along Santa Anita Avenue that contains 16 tenants. The proposed deal guarantees the city would receive at least $800,000 in sales tax a year for the next 10 years.
