EXECUTIVE SUMMARY 2.1 INTRODUCTION The Executive Summary chapter of the EIR provides an overview of the proposed project (see Chapter 3, Project Description, for further details) and provides a table summary of the conclusions of the environmental analysis provided in Chapters 4.1 through 4.4. This chapter also summarizes the alternatives to the proposed project that are described in Chapter 6, Alternatives Analysis, and identifies the Environmentally Superior Alternative. Table 2-1 contains the environmental impacts associated with the proposed project, the significance of the impacts, the proposed mitigation measures for the impacts, and the significance of the impacts after implementation of the mitigation measures. Environmental issues dismissed in the Initial Study are discussed in Chapter 4.0, Introduction to the Analysis, of this EIR. 2.2 SUMMARY DESCRIPTION OF THE PROPOSED PROJECT The project site consists of two parcels totaling approximately 5.2 acres that abut the eastern boundary of Casa Grande Road in the City of Petaluma. The 280 Casa Grande Road parcel contains an existing residence and undeveloped land covered in non-native grasses. The 270 Casa Grande Road parcel contains an existing residence, several associated outbuildings, a landscaped backyard, and a small orchard in the northeast corner of the project site, within a depressed area, near Adobe Creek (Creek). The Creek and its associated riparian corridor forms the eastern boundary of the project site (Assessor's Parcel Number [APN] 017-410-042). The remaining portions of the 270 Casa Grande Road parcel are generally characterized by grasses that are routinely mowed or grazed to reduce fire hazards. According to the City's General Plan, the project site is designated Medium Density Residential. The project site is zoned Residential (R4). The project site is bound to the west by Casa Grande Road and to the east by the Creek and its associated riparian corridor. The project site's northern boundary abuts the Casa Grande Senior Apartments. A single-family residence is located further to the north. A single-family residential neighborhood is located to the east, across the Creek, with access from Spyglass Road. Further east from the single-family residences is a multifamily neighborhood, to which Lakeville Circle provides access. The project site's southern boundary abuts the recently completed Casa Grande Subdivision. An existing single-family residential neighborhood is located further to the south and abuts the southern property line of the Casa Grande Subdivision site. Casa Grande High School and Crinella Park are located to the west, across Casa Grande Road, from the project site. It should be noted that Sonoma Mountain High School, an alternative high school in the City, is also located on the Casa Grande High School campus. Project Description The proposed project would include demolition of the on-site residence at 280 Casa Grande Road, retention of the existing residence at 270 Casa Grande Road, and development of 59 dwelling units. The proposed dwelling units would be constructed across three blocks. Block 1 units would be arranged in tri-plex configurations. Units within Blocks 2 and 3 would primarily be arranged in duet unit configurations. Each dwelling unit would include Usable Open Space (UOS) in the form of semi-private or private yard areas. In addition,the project would include construction Chapter 2 - Executive Summary Ai Page 2-1 Docusign Envelope ID:492CF6C7-3C9A-449F-8AOB-FF7C50575E8E Draft EIR 270 and 280 Casa Grande Road Creekwood Housing Development Project July 2024 of various on-site road and utility improvements, landscaping, and a new off-site public multi-use pathway, with a pedestrian bridge connection over the Creek. The project would require City approval of a Vesting Tentative Parcel Map, Site Plan and Architectural Review, and a Tree Removal Permit. In addition, the project would require other approvals from responsible and trustee agencies, including, but not necessarily limited to, CDFW approval of a 1600 Lake and Streambed Alteration Agreement and Regional Water Quality Control Board (RWQCB) approval of a Section 401 Water Quality Certification, a National Pollutant Discharge Elimination System (NPDES) Construction and MS4 General Permit. Project Approvals The proposed project would require City of Petaluma approval of the following entitlements: • Vesting Tentative Parcel Map; • Site Plan and Architectural Review; and • Tree Removal Permit. In addition to the above City approvals, the proposed project could require the following approvals/permits from other responsible and trustee agencies: • Section 401 Water Quality Certification (RWQCB- San Francisco Bay Region); • Section 1600 Lake and Streambed Alteration Agreement (CDFW-Region 3); • NPDES Construction General Permit (RWQCB -San Francisco Bay Region); and • NPDES Phase II MS4 General Permit (RWQCB- San Francisco Bay Region). While not a State Responsible Agency, the proposed project could require issuance of a Clean Water Act Section 404 permit by the U.S. Army Corps of Engineers, if the project would result in discharges of fill below the Ordinary High-Water Mark of the Creek. Please refer to Chapter 3, Project Description, of this EIR for a detailed description of the proposed project and entitlements, as well as a full list of the project objectives. 2.3 ENVIRONMENTAL IMPACTS AND PROPOSED AND RECOMMENDED MITIGATION Under CEQA, a significant effect on the environment is defined as a substantial, or potentially substantial, adverse change in any of the physical conditions within the area affected by the project, including land, air, water, mineral, flora, fauna, ambient noise, and objects of historic or aesthetic significance. Mitigation measures must be implemented as part of the proposed project to reduce potential adverse impacts to a less-than-significant level. Such mitigation measures are noted in this EIR and are found in the following technical chapters: Biological Resources; Greenhouse Gas (GHG) Emissions; Hydrology and Water Quality; and Transportation. Additionally, the Initial Study prepared for the proposed project (see Appendix A) includes mitigation measures that must be implemented as part of the proposed project associated with the following resource areas: Cultural Resources; Geology and Soils; Hazards and Hazardous Materials; Noise; and Tribal Cultural Resources. The mitigation measures required for the proposed project, as presented in this EIR and the Initial Study, will form the basis of the Mitigation Monitoring and Reporting Program. Any impact that remains significant after implementation of mitigation measures is considered a significant and unavoidable impact. Environmental issues Chapter 2 - Executive Summary 11 Page 2-2 Docusign Envelope ID:492CF6C7-3C9A-449F-8AOB-FF7C50575E8E Draft EIR 270 and 280 Casa Grande Road Creekwood Housing Development Project July 2024 dismissed in the Initial Study are further discussed in Chapter 4.0, Introduction to the Analysis, of this EIR. A summary of the impacts identified in each technical chapter (Chapters 4.1 through 4.4) of the EIR, as well as the Initial Study (see Appendix A) is presented in Table 2-1 included at the end of this chapter. In addition, Table 2-1 includes the level of significance of each impact, any mitigation measures required for each impact, and the resulting level of significance after implementation of mitigation measures for each impact. 2.4 SUMMARY OF PROJECT ALTERNATIVES_ The following section presents a summary of the alternatives evaluated in this EIR for the proposed project, which include the following: • No Project (No Build)Alternative; • No Bridge Alternative; and • Affordable Housing Alternative. For a more thorough discussion of project alternatives that were evaluated in this EIR, including alternatives considered but dismissed, please refer to Chapter 6, Alternatives Analysis. No Project (No Build) Alternative The No Project (No Build) Alternative assumes that the project site would remain in its current condition and would not be developed. As described in this EIR, the 280 Casa Grande Road (Assessor's Parcel Number [APN] 017-040-016) parcel contains an existing residence and undeveloped land covered in grasses. The 270 Casa Grande Road (APN 017-040-051) parcel contains an existing residence, several associated outbuildings, a landscaped backyard, and a small orchard in the northeast corner of the project site, within a depressed area, near the Creek, which forms the eastern boundary of the project site. The remaining portions of the 270 Casa Grande Road parcel are generally characterized by grasses that are routinely mowed or grazed to reduce fire hazards. Grazing of both parcels is conducted by several sheep owned and cared for by the current 270 Casa Grande Road property owner. Although none of the impacts identified for the proposed project would occur under the No Project (No Build) Alternative, the No Project (No Build) Alternative would not meet any of the project objectives. No Bridge Alternative The No Bridge Alternative would include demolition of the on-site residence at 280 Casa Grande Road, retention of the existing residence at 270 Casa Grande Road, development of 59 dwelling units, construction of various on-site road and utility improvements, landscaping, and a new off- site public multi-use pathway. However, the bridge connection over the Creek for the public multi- use pathway would not be developed under the No Bridge Alternative. Given that the majority of on- and off-site improvements required under the No Bridge Alternative would still be developed, the Alternative would still require a Vesting Tentative Parcel Map, Site Plan and Architectural Review, and a Tree Removal Permit. In addition, because the No Bridge Alternative would generally result in similar development of the proposed project, Objectives#1 through #3, #6, and #7 would be fully met. However, because the bridge connection would not be developed Objective #4 would only be partially met, and Objective #5 would not be met. / Chapter 2 - Executive Summary Page 2-3 Docusign Envelope ID:492CF6C7-3C9A-449F-8AOB-FF7C50575E8E Draft EIR 270 and 280 Casa Grande Road Creekwood Housing Development Project July 2024 Relative to the proposed project, the No Bridge Alternative would result in fewer impacts related to biological resources and hydrology and water quality and greater impacts related to GHG emissions and transportation. The significant and unavoidable impacts to GHG emissions and transportation that were identified for the proposed project would remain under the No Bridge Alternative. Given that development of the No Bridge Alternative would involve a similar disturbance footprint and development of the same land uses as compared to the proposed project, impacts associated with the other CEQA topics in which the proposed project could have significant impacts, as identified in the Initial Study (cultural resources, geology, hazards, noise, and tribal cultural resources), would be anticipated to be similar in scale under the No Bridge Alternative. Affordable Housing Alternative Under the Affordable Housing Alternative, the 59 residential units proposed to be developed on- site would be offered as affordable housing. All other on- and off-site improvements proposed as part of the project, including demolition of the on-site residence at 280 Casa Grande Road, retention of the existing residence at 270 Casa Grande Road, construction of various on-site road and utility improvements, landscaping, and a new off-site public multi-use pathway, with a bridge connection over the Creek, would remain the same. Given that all on- and off-site improvements required under the Affordable Housing Alternative would be the same as the proposed project, the Alternative would still require a Vesting Tentative Parcel Map, Site Plan and Architectural Review, and a Tree Removal Permit. In addition, because the Affordable Housing Alternative would generally result in similar development of the proposed project, all project objectives would be met. The Affordable Housing Alternative would result in fewer impacts related to GHG emissions and transportation, and similar impacts related to biological resources and hydrology and water quality. Given that development of the Affordable Housing Alternative would involve the same disturbance footprint and development of the similar land uses as compared to the proposed project, impacts associated with the other CEQA topics in which the proposed project could have significant impacts, as identified in the Initial Study (cultural resources, geology, hazards, noise, and tribal cultural resources), are anticipated to be similar in scale under the Affordable Housing Alternative. Environmentally Superior Alternative An EIR is required to identify the environmentally superior alternative from among the range of reasonable alternatives that are evaluated. Section 15126(e)(2) of the CEQA Guidelines requires that an environmentally superior alternative be designated and states, "If the environmentally superior alternative is the `no project' alternative, the EIR shall also identify an environmentally superior alternative among the other alternatives." In this case, the No Project (No Build) Alternative would be considered the environmentally superior alternative, because the project site is assumed to remain in its current condition under the alternative. Consequently, impacts resulting from the proposed project would not occur under the Alternative. The No Project (No Build) Alternative would not meet any of the project objectives. Both the No Bridge Alternative and the Affordable Housing Alternative would meet most project objectives. As previously noted, the No Bridge Alternative would fully meet Objectives #1 through #3, #6, and #7. However, because the bridge connection would not be developed, Objective #4 would only be partially met, and Objective #5 would not be met. The Affordable Housing Alternative would meet all objectives. Chapter 2 - Executive Summary 11 Page 2-4 Docusign Envelope ID:492CF6C7-3C9A-449F-8AOB-FF7C50575E8E Draft EIR 270 and 280 Casa Grande Road Creekwood Housing Development Project July 2024 The No Bridge Alternative could result in greater impacts than the proposed project related to GHG emissions and transportation; fewer impacts related to biological resources and hydrology and water quality, and similar impacts to the proposed project for cultural resources, geology and soil, hazards and hazardous materials, noise, and tribal cultural resources. The Affordable Housing Alternative would result in fewer impacts related to GHG emissions and transportation, and similar impacts to the proposed project for biological resources, cultural resources, geology and soil, hazards and hazardous material, hydrology and water quality, noise, and tribal cultural resources. Based on the above, the Affordable Housing Alternative would be considered the environmentally superior alternative to the proposed project. 2.5 AREAS OF KNOWN CONTROVERSY Areas of controversy that were identified in NOP comment letters, and are otherwise known for the project area, include the following: • Concerns related to special-status wildlife species, such as California coast steelhead, Pacific salmon, and migratory birds protected under the federal Migratory Bird Treaty Act; special-status plant species; and designated critical habitat; • Potential impacts to Adobe Creek and associated riparian habitat; • Increased potential for flooding due to increases in impervious surface area; • Concerns related to increases in traffic and vehicle miles traveled; • Insufficient quality of Ely Boulevard in the project vicinity; • Potential impacts to emergency evacuation routes; • Safety concerns related to the lack of sidewalks in the vicinity of the proposed project; • Concerns related to access to transit connections, types of transit connections, and the connection between the project site and nearby activity centers; • Aesthetic impacts of building the proposed bridge across the Creek; • Increased traffic noise, as well as increases in pedestrian noise along the proposed bridge across the Creek; • Inadvertent discovery of Native American resources and/or human remains; and • Inconsistency with City goals to develop housing in central Petaluma.

A meandering pedestrian survey shall be conducted throughout the area proposed for impact in order to identify patches of suitable floral resources. Suitable floral resources for western bumble bee include species in the following families: Asteraceae, Fabaceae, Rhamnaceae, and Rosaceae, as well as plants in the genera Eriogonum and Penstemon. At a minimum, preconstruction survey methods shall include the following: • Search areas with floral resources for foraging western bumble bees. Observed foraging activity may indicate a nest is nearby, and therefore, the survey duration shall be increased when foraging western bumble bees are present,- If western bumble bees are observed, watch any special-status western bumble bees present and observe their flight patterns.
