WHITTIER >> The momentum of 2014's economic development surge is expected to carry over into 2015, according to City Manager Jeff Collier and Conal McNamara, director of economic development. Leading a long list of projects that will continue or start in 2015 is the redevelopment of the former Fred C. Nelles Youth Facility, which will continue through the regulatory process into February, with infrastructure construction work starting possibly by mid-summer, but definitely sometime in 2015, Collier and McNamara said.
