The early version of the LPC initially held little power over enforcement, and failed to avert Pennsylvania Station's demolition. As a result, in April 1964, LPC member Geoffrey Platt drafted a New York City Landmarks Law. Outcry over the proposed destruction of the Brokaw Mansion on Manhattan's Upper East Side, identified by the LPC as a possible landmark, inspired Wagner to send the legislation to the New York City Council in mid-1964. The law, introduced in the City Council that October, would significantly increase the LPC's powers. The City Council cited concerns that "the City has been and is undergoing the loss and destruction of its architectural heritage at an alarming rate, especially so in the last 8-10 years". Several changes to the Landmarks Law were made by the City Council committee that was reviewing the legislation; for example, the committee removed a clause mandating a protective zone around proposed landmarks. The bill passed the City Council on April 7, 1965, and was signed into law by Wagner on April 20.
