Residents in western Marin and Novato will soon gain access to broadband internet service through fiber-optic cable thanks to $11.28 million in state and federal grants. Marin County was awarded $11 million to fund the construction of a broadband network to about 700 homes and businesses in Muir Beach, Tomales and Dillon Beach. Comcast received a grant of $280,643 to cover half of the cost of installing fiber-optic connections at 152 unserved residences at the Los Robles Mobile Home Park in Novato.
