CLEARWATER - Volunteers helped raise the trusses on the Hubbard-Lapos family's soon-to-be new Habitat for Humanity home.Habitat for Humanity of Pinellas County kicked off its annual "Blitz Build" event on Valentine's Day. Starting at 7 a.m. volunteers began working on two houses, for Freda Dixon and her daughter and the Hubbard-Lapos family.Over 300 volunteers will turn out to help the nonprofit build the homes for low income families in Habitat's Stevens Creek subdivision at 1884 N. Betty Lane, in Clearwater. Depending on the day, 30 to 80 volunteers each day will help Habitat Pinellas transform two concrete slabs and block walls into homes. During the seven-day build period, volunteers will work one of two shifts daily: 7 a.m. until noon and noon to 6 p.m.One home will be dedicated to the Dixons at 1 p.m. Sunday, Feb. 23 and volunteers will also complete 75 percent of work on the second home, which is being partially built during the event for the Hubbard-Lapos family. Due to medical circumstances, that home's family members cannot participate in the Blitz Build, so a portion of the work on that home will be saved for the family to help complete later in the spring, per Habitat requirements.
