23 standard for City Streets (DTPP p. 59, "Public Frontage Regulations Chart"). According to project component plans, the project component proposes to install new single head street lighting fixtures as follows: three along the Broadway frontage, three along Marshall Street, and four along Walnut Street; in addition, four new twin acorn style lighting fixtures along Main Street (Plan Sheet LT1, 11/9/23). These fixtures would be in compliance with Lighting Zone 3 and Title 24 standards and would thereby minimize the impact of new sources of light pollution and not create a new source of substantial light or glare which would adversely affect day or nighttime views in the area. For these reasons, the 1900 Broadway project component would have a less than significant impact, and is consistent with the analysis in the EIR/SEIR because it would not create new impacts or increase impacts, and there is no new information of substantial importance for CEQA purposes. e. For the Downtown Precise Plan program EIR (pp. 6-13 and 6-14), the City determined that any new structure within the DTPP area that would cause identified shadow-sensitive uses and spaces to be more than 50 percent in shadow at 12:00 PM (noon) on the Spring Equinox (March 20) would impair the livability and beneficial uses of those shadow- sensitive uses and spaces, in which case a significant environmental impact would result. The City conducted extensive and detailed studies regarding the potential shadow impacts that might result from the Downtown’s expected increases in building heights (DTPP program EIR Appendix 21.3 - Supplemental Shadow Analysis Information). As a result, the DTPP development standards were developed with the specific intent to avoid significant shadow impacts (EIR p. 6-29). Full buildout of the DTPP to the maximum building envelopes allowed by the Plan’s standards would not cause any shadow-sensitive uses and spaces to be more than 50 percent in shadow at noon on the Spring Equinox. The impact of the DTPP was considered to be less than significant, and no mitigations were needed. The DTPP Plan-Wide Amendments program SEIR (pp. 6-13 through 6-14) generally concurred with the DTPP EIR conclusion but determined that because development under the amended DTPP would be expected to increase, exceptions to height stepdown requirements or side setback requirements could be granted that might result in potentially significant impacts. Therefore, the DTPP Plan-Wide Amendments program SEIR (p. 6-14) included Mitigation Measure AE-5 (“Shadow Study for Exceptions to Building Placement and/or Building Height and Disposition Regulations”), which would require projects seeking exceptions to DTPP regulations pertaining to building placement and/or building height and disposition to demonstrate to City Staff that the exceptions would be consistent with the DTPP (section 2.7.5) and would not result in shadow exceeding 50 percent on the shadow-sensitive uses and spaces at noon on the Spring Equinox. The SEIR concluded that this mitigation measure would reduce the potential impacts related to shadow to a less-than-significant level. To address the DTPP shadow standard, the project component applicant provided a shadow study (“solar study”) that simulated project-generated shadows throughout the day for the Spring Equinox, Summer Solstice, Fall Equinox, and Winter Solstice (see Plan Sheet A13, 11/9/23). As discussed in the project description (item #8 above), maximum project component building heights would not exceed 92’ at the parapet (seven stories) plus an additional allowed 10’ for the rooftop mechanical/penthouse screening, totaling a maximum building height of 102’ with the following step- down heights consistent with the DTPP : (1) along the Main Street frontage, consistent with the DTPP-required 35’ setback along Main Street, building heights would be 34’ (three stories, consistent with the DTPP-required stepdown zone) along the approximately 145’-building portion from Marshall Street south to the public common area; and (2) along the Broadway frontage, and extending approximately 46’ consistent with the DTPP-required 35’ setback along Broadway, buildings would be 34’ tall (three stories, consistent with the DTPP-required stepdown zone) along the approximately 150’-building portion from Walnut Street west to the public common area. As also indicated in the project component plans, these maximum building heights would allow for variations in building articulation to allow for building elements such as rooftop terraces and balconies (Plan Sheets A4, A8, A9, A10.1, A10.2, A11.1, and E9, 11/9/23). The study showed that shadows would not cause any shadow-sensitive uses to be more than 50 percent in shadow at noon on the Spring Equinox. Shadows would generally extend northward (with eastern and western parts depending on time of day, but would not extend beyond Marshall Street and some parts of Main Street or Walnut Street depending on time of day, except for the winter period (October through January). Then, shadow would extend across Marshall Street and some parts of Main Street or Walnut Street depending on time of day. Also, no shadows would be cast on any portion of the Main Street Historic District, which is south of the project component site. Because the shadow study showed that shadows from the proposed project component would not cause any shadow-sensitive uses to be more than 50 percent in shadow at noon on the Spring Equinox, and the proposed project components would be in compliance with all applicable DTPP standards regarding shadows, no additional shadow impacts would be anticipated. The 1900 Broadway project component would have a less than significant impact for the reasons noted. Therefore, the 1900 Broadway project component would be consistent with the analysis in the EIR/SEIR and would not create new impacts or increase impacts, and there is no new information of substantial importance for CEQA purposes.
