Sen. Marvin Blyden, chairman of the Housing, Public Works, Waste Management and Planning will have office hours on St. John today. Although the senator will be chairing a Senate Committee hearing on the island of St. Thomas the same day, members of his staff will be in the St. John Legislative office to assist with any issues residents of the St. John community would like to present to him. He will be on St. John every first Wednesday of the month.
