FROM: Paul Maltzer, Environmental Review Officer
SUBJECT: Request for the Final Environmental Impact Report for the Golden Gate Park
Concourse Authority Projects (Case No. 2001.91IE)
This is the Draft ofthe Environmental Impact Report (EIR) for the Golden Gate Park
A
Concourse Authority Projects. public hearing will be held on the adequacy and accuracy of
this document. After the public hearing, we will prepare and publish a document titled
"Summary of Comments and Responses" that will contain a summary of all relevant
comments on this Draft EIR and our responses to those comments. It may also specify changes
to this Draft EIR. Those who testify at the hearing on the Draft EIR will automatically receive
a copy ofthe Comments and Responses document, along with notice ofthe date reserved for
certification; others may receive such copies and notice on request or by visiting our office.
This Draft EIR together with the Summary ofComments and Responses document will be
considered by the City Planning Commission in an advertised public meeting(s) and certified
as a Final EIR ifdeemed adequate.
After certification, we will modify the Draft EIR as specified by the Comments and Responses
document and print both documents in a single publication called the Final EIR. The Final EIR
will add no new information to the combination ofthe two documents except to reproduce the
certification resolution. It will simply provide the information in one, rather than two,
documents. Therefore, ifyou receive a copy ofthe Comments and Responses document in
addition to this copy ofthe Draft EIR, you will technically have a copy of the Final EIR.
We are aware that many people who receive the Draft EIR and Summary of Comments and
Responses have no interest in receiving virtually the same information after the EIR has been
certified. To avoid expending money and paper needlessly, we would like to send copies ofthe
Final EIR to private individuals only ifthey request them. If you would like a copy ofthe
Final EIR, therefore, please fill out and mail the postcard provided inside the back cover to the
San Francisco Planning Department within two weeks after certification ofthe EIR. Any
private party not requesting a Final EIR by that time will not be mailed a copy. Public
agencies on the distribution list will automatically receive a copy of the Final EIR.
Thank you for your interest in this project.
