In November 2013 the Draft EIR (SCH No. 2013032079) for the proposed project was made available for public comment for a 45‐day review period. The City of Pittsburg (City) received nine comment letters during this period. Some of the comments received on the Draft EIR provided new information with regard to biological resources on the project site. After reviewing this new information, the City, which is the lead agency for the environmental review of the proposed project, determined that it was necessary to add this new information to the Draft EIR, and in order to comply with the requirements of the California Environmental Quality Act (CEQA) and State CEQA Guidelines, those portions of the Draft EIR that are affected by the new information should be recirculated. The characteristics of the Montreux Residential Subdivision project have not changed since the publication of the November 2013 Draft EIR. The proposed Montreux Residential Subdivision project consists of: 1. a request for rezoning of the main project site from its current pre‐zoning designation of HPD (Hillside Planned Development) District to RS‐6 (Single‐Family Residential) District, which would be consistent with the existing General Plan designation of Low Density Residential; 2. a request for approval of a Vesting Tentative Map (Subdivision No. 8279) and preliminary grading plan for 356 single‐family homes with lots averaging approximately 7,668 sq. ft. in size; 3. annexation of the main project site into the City of Pittsburg, Contra Costa Water District (CCWD) Service Area (including inclusion into the Central Valley Project), and the Delta Diablo Sanitation District (DDSD) Service Area; and 4. approval of a Development Agreement vesting the entitlements for an extended term of project approval. Overall, approximately 77 acres of the main project site would be devoted to residential uses, and the remaining 71 acres would be set aside for open space. The average density on the main project site would be 2.4 units per acre. This Recirculated Draft EIR will be used, in conjunction with the November 2013 Draft EIR, to inform city decision makers, responsible and trustee agencies, other public agencies, and members of the public of the potential environmental effects associated with the implementation of the Montreux Residential Subdivision project. Impact Sciences, Inc. 1.0‐1 Montreux Residential Subdivision Recirculated Draft EIR 0884.005 December 2014 1.0 Introduction PURPOSE OF THIS RECIRCULATED DRAFT EIR This Recirculated Draft EIR has been prepared pursuant to Section 15088.5 of the State CEQA Guidelines. A lead agency is required to recirculate an EIR when significant new information is added to the EIR after public notice is given of the availability of the Draft EIR but prior to certification. The term “information” can include changes in the project or environmental setting as well as additional data or other information. New information is not “significant” unless the EIR is changed in a way that deprives the public of a meaningful opportunity to comment on a substantial adverse impact of the project or a feasible way to mitigate or avoid such an effect. The City has added information with regard to the project’s biological setting, direct impacts to sensitive plant and wildlife species, and indirect impacts to special‐status wildlife and determined that the revised analysis represents significant new information and therefore portions of the Draft EIR must be recirculated to provide the public an opportunity to comment on the project’s potential impacts on biological resources. SCOPE OF THIS RECIRCULATED DRAFT EIR According to Section 15088.5 (c) of the State CEQA Guidelines, if the revisions to the previously circulated Draft EIR are limited to a few chapters of the EIR, the lead agency is required to recirculate only those portions of the EIR that have been modified by the changes in the project or the project’s environmental setting. The City has decided to prepare a Recirculated Draft EIR and recirculate only those sections of the previously circulated Draft EIR that have been affected by the additional information related to biological resources. Therefore, this Recirculated Draft EIR includes the following: Executive Summary (replacing Chapter 2.0 of the November 2013 Draft EIR) Biological Resources (replacing Chapter 5.0, Section 5.3 of the November 2013 Draft EIR) Alternatives (replacing Chapter 6.0 of the November 2013 Draft EIR) Document Preparation (replacing Chapter 8.0 of the November 2013 Draft EIR) Pursuant to Section 15088.5(f)(2), the City is requesting that reviewers of this document submit new comments related to the revised information on biological resources presented in the Recirculated Draft EIR chapters only. The comments on the November 2013 Draft EIR have become part of the administrative record and those comments regarding issues not addressed in this Recirculated Draft EIR will be responded to in the Final EIR. Comments on the previous analysis pertaining to biological resources have been addressed in the revised Biological Resources section of this Recirculated Draft EIR. Any new comments on this Impact Sciences, Inc. 1.0‐2 Montreux Residential Subdivision Recirculated Draft EIR 0884.005 December 2014 1.0 Introduction Recirculated Draft EIR must be submitted during the public comment period for this Recirculated Draft EIR if the commenter wishes to receive a written response in the Final EIR. REPORT ORGANIZATION This Recirculated Draft EIR is organized into the following sections with the revised sections numbered to correspond to the same sections in the previously circulated Draft EIR: Chapter 1.0, Introduction, summarizes the purpose and organization of the Recirculated Draft EIR. Chapter 2.0, Executive Summary, summarizes environmental consequences that would result from the implementation of the proposed Montreux Residential Subdivision project, provides a summary table that identifies significant environmental impacts, describes mitigation measures, and indicates the level of significance of impacts before and after mitigation. The summary table is unchanged from the November 2013 Draft EIR, except as to biological resources

College Avenue Claremont, Calif. 91711 ABSTRACT The Liebre Mountains form a discrete unit of the Transverse Ranges of southern California. Geo­ graphically, the range is transitional to the San Gabriel Mountains, Inner Coast Ranges, Tehachapi Mountains, and Mojave Desert. A total of 1010 vascular plant taxa was recorded from the range, representing 104 families and 400 genera. The ratio of native vs. nonnative elements of the flora is 4:1, similar to that documented in other areas of cismontane southern California. The range is note­ worthy for the diversity of Quercus and oak-dominated vegetation. A total of 32 sensitive plant taxa (rare, threatened or endangered) was recorded from the range.

I have desired to complement this body of information with studies on the anatomy of the subtribe so that a more adequate picture of variation and evolution in this remarkable group could be obtained. The anatomical diversity of the Madinae is, in fact, no less interesting than the variation patterns in cytological, genetical, and morphological characters. The latter features lend themselves well to studies of speci­ ation, whereas the anatomical characters evidence trends in the development of genera or criteria for defining the group as a whole. In a number of instances, species dif­ ferences are also revealed by anatomical studies. The primary focus of this study is the definition of the subtribe and its genera, and the exposition of phyletic tendencies within the Madinae by combination of anatomical data with that of other disciplines.

HARMON-THREATT† and C L A I R E KREMEN Department of Environmental Science, Policy and Management, University of California, Berkeley, California, U.S.A. Abstract. 1. Changes to plant community composition after invasion are well docu- mented but how these shifts directly affect higher trophic levels is still poorly understood. One potentially important factor is the change in nutritional availability after an inva- sion. Shifts in nutrient availability could affect the nutrient intake of organisms that live in invaded habitats, causing reduced fecundity and survival. 2. The effects of the interaction among nutrient availability, selection, and diet on nutrient intake of a native bumble bee were examined. No nutritional differences were found between exotic and native pollen or collected and non-collected pollen in protein or amino acid content, suggesting that differences in nutrient intake from random are based on selection. 3. Nutrient intake was simulated when pollen was selected randomly across all available plant species and when selection was restricted to native plants only or exotic plants only using a permutation model and compared with observed collection.
