SUBJECT: Request for the Final Supplemental Environmental Impact Report for the
Executive Park Development Plan project
(Planning Department File No. 1999.442E)
This is the Draft of the Supplemental Environmental Impact Report (SEIR) for the Executive
A
Park Development Plan project. public hearing will be held on the adequacy and accuracy
of this document. After the public hearing, our office will prepare and publish a document
titled "Summary of Comments and Responses" that will contain a summary of all relevant
comments on this Draft SEIR and our responses to those comments. It may also specify
changes to this Draft SEIR. Those who testify at the hearing on the Draft SEIR will
automatically receive a copy ofthe Comments and Responses document, along with notice of
the date reserved for certification; others may receive such copies and notice on request or by
visiting our office. This Draft SEIR together with the Summary of Comments and Responses
document will be considered by the City Planning Commission in an advertised public meeting
and certified as a Final SEIR if deemed adequate.
After certification, we will modify the Draft SEIR as specified by the Comments and
Responses document and print both documents in a single publication called the Final SEIR.
The Final SEIR will add no new information to the combination of the 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 SEIR, you will technically have a copy of the
Final SEIR.
We are aware that many people who receive the Draft SEIR and Summary of Comments and
Responses have no interest in receiving virtually the same information after the SEIR has been
certified. To avoid expending money and paper needlessly, we would like to send copies of
the Final SEIR to private individuals only ifthey request them. Ifyou would like a copy of
the Final SEIR, therefore, please fill out and mail the postcard provided inside the back cover
to the Major Environmental Analysis Office ofthe Planning Department witliin two weeks
after certification ofthe SEIR. Any private party not requesting a Final SEIR by that time will
not be mailed a copy. Public agencies on the distribution list will automatically receive a copy
ofthe Final SEIR.
Thank you for your interest in this project.

SUMMARY
I.
BACKGROUND
A.
In 1985, the San Francisco Planning Commission approved a development program for the
Executive Park site, which included 1,644,000 sq. ft. of office space, a 350-room hotel
totaling 234,000 sq. ft., 50,000 sq. ft. ofretail and restaurant space, 600 dwelling units
totaling 425,000 sq. ft., and about 5,270 parking spaces. In 1992, the Planning Commission
modified the authorization to change the composition ofthe 600 residential units from
predominately studios and one-bedroom units to predominantly multi-bedroom units, resulting
in 600 dwelling units totaling 850,000 sq. ft.; and added a health club/restaurant of
35,000 sq. ft. and a day care center of 10,000 sq. ft. The first three office buildings,
comprising about 320,000 sq. ft., and about 800 surface parking spaces occupy the site.
About 287 dwelling units and related parking (532 spaces) are under construction on the east
end ofthe site.
The currently proposed project would extend the termination date for the project authorization
beyond December 1999 and would modify the Conditional Use authorization approved by the
Planning Commission. The modifications would include deletion ofthe requirement for
extension ofExecutive Boulevard West, substitution ofhillside revegetation for a hillside trail,
a change in the amount contributed toward some transportation improvements, and an increase
in permitted nonresidential parking.
The project was analyzed in the Executive ParkDevelopment Plan AmendmentFinal
SubsequentEnvironmental ImpactReport (81.197E, certified October 17, 1985)("1985
FSEIR"), and the San Francisco Planning Commission approved the development program,
with conditions, in October 1985. AnAddendum to the 1985 FSEIR (90.299E, dated
February 13, 1992)("1992 Addendum"), evaluated modifications to the project including

Summary
I.
changes in the composition ofthe residential units and allowance of a health club/restaurant of
35,000 sq. ft. and a day care center of 10,000 sq. ft.
The project as proposed contains differences from the approved project, including dispersion
of retail uses, revegetation of the hillside without hillside trails, delay in implementing the
extension of Executive Park Boulevard West, reduction in the number of residential units, and
a proposed request for an increase in allowable parking. In addition, conditions in the project
area have changed substantially since completion ofthe 1985 FSEIR. For these reasons, the
Planning Department determined that a Supplemental EIR is required.
This SEIR updates the description of existing conditions contained in the 1985 Final
Subsequent EIR, and re-assesses impacts for impact areas with changed methodologies and
baseline conditions, including transportation, air quality, and noise. The other environmental
topics are discussed in the context ofthe previous analyses conducted. These previous
analyses, including the 1985 FSEIR and the 1992 Addendum, are incorporated herein by
reference, and will be made available to decision-makers who must consider whether to extend
and amend the 1992 project authorization. Copies ofthe 1985 FSEIR and 1992 Addendum are
available for review at the San Francisco Planning Department, 1660 Mission Street.
PROJECT DESCRIPTION
B.
The project sponsor, Universal Paragon, is requesting an extension for their previously
approved project beyond December 1999 and modification ofthe Conditional Use
authorization approved by the City Planning Commission. Build-out of the project's
remaining development would occur on about halfofthe 71-acre project area, which includes
portions of Lots 75, 85, 86 and 88/90 ofAssessor's Block 4991, and Lots 24, 61, and 65 of
Assessor's Block 153. Development would occur in four areas: north of Executive Park
