I. Introduction and Overview
This report describes the results of an analysis conducted by PreVision Design to
identify the shadow effects that would be caused by the proposed construction of
a four-story residential project at 875 California Street (“the proposed project” or
“875 California Street”) on St. Mary's Square, Willie “Woo Woo” Wong Playground,
and Portsmouth Square Plaza, public parks protected under Section 295 of the San
Francisco Planning Code as well as publicly accessible open spaces at 555, 600 &
650 California Street. The project sponsor is Reuben Junius & Rose, and the project
architect is Robert A.M. Stern Architects (RAMSA).
The analysis was conducted according to criteria described in (1) the February 3,
1989 memorandum titled “Proposition K – The Sunlight Ordinance” prepared by
the San Francisco Recreation and Park Department (RPD) and the San Francisco
Planning Department (“the 1989 Proposition K memorandum”), and (2) the July 2014
memorandum titled “Shadow Analysis Procedures and Scope Requirements” prepared
by the Planning Department.
PreVision Design has concluded that the project as proposed will not result in any
new shadows falling on St. Mary's Square, Willie “Woo Woo” Wong Playground,
Portsmouth Square Plaza, protected under Section 295 of the Planning Code, nor
the nearby public open spaces at 555, 600, and 650 California Street. Accordingly,
this report consists of a description of the proposed project, the parks or open spaces
in question, and a graphical analysis showing the extents of new shadow relative to
St. Mary's Square, Willie “Woo Woo” Wong Playground, Portsmouth Square Plaza and
other publicly accessible open spaces. n

II. Proposed Project
The proposed project would be located on two lots totaling 15,548-square-foot (sf) in
the Chinatown neighborhood of San Francisco on Assessor’s Block 0256/ Lots 016-017.
Figure 1 shows the location of the proposed project. The project site is located at the
southeast corner of California and Powell Streets and currently has a 2-story parking
structure at 875 California Street and a 20 space parking lot at 770 Powell Street. The
project is within Nob Hill Special Use District, Residential-Mixed, High Density (RM-
4) Zoning District and 65-A Height and Bulk District.
The project proposes to construct an 8-story, 65-foot-tall residential building containing
2 studios, 7 one-bedroom, 30 2-bedroom and 5 3-bedroom units, and below-grade
parking including 48 vehicle and 46 bicycle spaces accessible from Powell Street and
extending to California Street on the northwest corner. In total, the proposed project
would provide approximately 63,673 gsf of residential uses. Figure 2 shows a rendering
of the proposed project, Figure 3 shows the proposed project site plan, and Figures 4-8
show proposed building elevations. n

IV. Section 295 METHODOLOGY and findings
Proposed buildings that would be more than 40 feet tall and that could cause new
shadow in parks under the control of the RPD are subject to review under Section 295
of the San Francisco Planning Code. Section 295 requires the Planning Commission
to deny building permits for projects that would have adverse shadow impacts on these
parks, unless the impacts are found to be insignificant.
Following the direction provided by Section 295, an adverse impact is defined as
the addition of new shadow from any development over 40 feet in height at any time
throughout the year at times between one hour after sunrise through one hour before
sunset, unless the Planning Commission, with input from the general manager of the
RPD and the Recreation and Park Commission, determines that the impact would be
insignificant. (In this report, the term “Section 295 cutoff times” refers to one hour after
sunrise and one hour before sunset, and “Section 295 start time” refers to one hour after
sunrise.)
The shadow analysis completed by PreVision Design for 875 California Street used
an accurately Geo-located 3D computer model of the proposed project, the park, and
the surrounding urban environment to simulate and calculate both existing amounts
of shading and levels of new shading (if any) that would be present with the addition
of the proposed project starting one hour after sunrise through one hour before sunset.
Between these Section 295 cutoff times, the model performed snapshot analyses at
15-minute intervals and repeated this process for every seven days between the Summer
Solstice and Winter Solstice. This half-year is referred to as a “solar year” for purposes
of this report, and the data taken from these 27 sample dates throughout the course of
the solar year are then mirrored with interim times and dates extrapolated to arrive at
P r evI S I o N D e S I G N | 87 5 C A L I F o r N I A S T r e e T S H A D o W A N A LY S I S r e P o r T | F I N A L | N o v e m b e r 1 3 , 2 01 5 PAGe 13
the full-year shading calculation. The difference between the current levels of shading
and the levels of shading that would be present with the addition of the proposed project
yields the total annual increase, measured in square-foot-hours (sfh) of shadow. This
increase is taken as a percentage of TAAS of sun in the park (the amount of sun that
would fall on the park throughout the year if there were no shading present at any time)
to determine whether the new shadows created by the proposed project would fall
within or outside the potentially permissible limits of increased shading.
The results of this analysis indicated that at no time throughout the year would
875 California Street cast new shadows on St. Mary's Square, Willie “Woo Woo” Wong
Playground or Portsmouth Square, nor the publicly accessible open spaces at 555, 600 &
650 California Street.
To document and substantiate this finding of no shading impact, PreVision Design has
prepared a full-year shading diagram to show the full range on locations where new
shading would occur, included as Exhibit A. As shown, at no time throughout the year
would new shadows be cast on any of the open spaces discussed in this report. n
