The Ferber Co. is considering redevelopment of a former Wells Fargo bank site in Mandarin for a Whataburger restaurant, according to an application with the city. The city received a mobility fee calcuation certificate application for a 3,751-square-foot Whataburger on the 1.42-acre site at 10600 San Jose Blvd. The fee is calculated at $113,606 to support the traffic impact. The 3,473-square-foot bank, built in 1980, had five teller/ATM lanes. Ferber paid $1.4 million on April 5 for the property, which is at southwest San Jose Boulevard and Hartley Road, north of Interstate 295. Tom Mundy, Ferber vice president of development services, said April 7 the highest and best use of the site is as a restaurant with a drive-thru.
