A large crowd was expected last night at the last of four City Council hearings on legislation that would allow the city to seize up to 3,300 properties for an East Baltimore biotech park and hundreds of units of new and renovated housing units.

The evening hearing was scheduled at Elmer A. Henderson Elementary School in the heavily blighted Middle East neighborhood just north of the Johns Hopkins medical complex, where the biotech park and two-thirds of the properties to be condemned are to be located. The biotech park is projected to be built over the next 10 years.
