FROM: Paul Maltzer, Environmental Review Officer
SUBJECT: Request forthe Final Environmental ImpactReport forthe 301 Mission Street Project
(Planning Department File No. 2001.0792E)
This is the Draft ofthe Environmental Impact Report (EIR) forthe 301 Mission Street Project. A
public hearing will be held on the adequacy and accuracy ofthis document. After the pubHc
hearing, our office will prepare and publish a document titled "Summary ofComments and
Responses" that will contain a summary ofall relevant comments on this Draft EIR and our
responses to those comments. It may also specify changes to this Draft EIR. Public agencies,
and members ofthe public 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 togetherwith the Summary ofComments and Responses document will be considered
by the Planning Commission in an advertisedpublic meeting and certified as a Final EIR if
deemed adequate.
After certification, we will modify the Draft EIR as specified by the Comments and Responses
document andprint both documents in a single publication called the Final EIR. The Final EIR
will add no new information to the combination ofthese two documents except to reproduce the
certification resolution. It will simply provide the information in one document rather than two.
Therefore, ifyou receive a copy ofthe Comments and Responses document in addition to this
copy ofthe Draft EIR, you will technically have a copy ofthe Final EIR.
We are aware that many people who receive the Draft EIR andthe Summary ofComments and
Responses have no interest in receiving virtually the same information afterthe EIR has been
certified. To avoid expending money and paper needlessly, wewould like to send copies ofthe
Final EIR to private individuals only ifthey request them. Ifyou would like a copy ofthe Final
EIR, therefore, please fill out and mail the postcard provided inside the back cover to the Major
Environmental Analysis Office ofthe 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 ofthe Final EIR.
Thankyou foryour interest in this project.
