Historic preservation problems in Baltimore
The tension between growth and historic preservation came to the fore in Baltimore when the planning director called for an evaluation of the executive director of the Commission on Historical and Architectural Preservation.
While this function is part of the Baltimore City Office of Planning, the executive director is hired/fired by the Commission, independent of the Executive Branch.
See "Preservation panel declines to vote on ouster of top director: Kathleen Kotarba has served for decades as head of the Commission for Historical and Architectural Preservation" and "City preservationists summoned to closed-door meeting" from the Baltimore Sun.
This is a typical problem across the country.
