John Shelton is out as executive director of the San Joaquin River Conservancy Board. Board members for the regional public agency voted 11-1 in a closed session vote Wednesday to look for a new leader. … Karbassi represents the Fresno City Council on the board. The conservancy is a state agency that plans and manages the San Joaquin River Parkway, a 22-mile area of the river between Highway 99 and the Friant Dam. Plans to improve the parkway have long been bogged down by bureaucracy and politics.
