Memo To: Amy Nicholson, Senior Planner From: Stantec Consulting Services Inc. City of Santa Rosa File: 3575 Mendocino Avenue Project Date: December 7, 2020 Reference: 3575 Mendocino Avenue Project – Errata Memorandum Stantec Consulting Services Inc. (Stantec) has prepared this Errata Memorandum (memo) to document revisions to the September 28, 2020 Sustainable Communities Environmental Assessment (SCEA) prepared for the proposed 3575 Mendocino Avenue Project (Project) under the California Environmental Quality Act (CEQA). PUBLIC REVIEW PROCESS On September 28, 2020, the City of Santa Rosa (City) circulated a Notice of Availability of the SCEA for a 30- day review and comment period by the public, and the responsible and reviewing agencies. The public review period ended on October 27, 2020. Following the completion of the public comment period, additional and continued outreach to interested parties and resource agencies took place, which resulted in minor editorial revisions to the language in the SCEA to clarify Biological and Cultural Resources mitigation measures. As such, the following memo has been prepared to document and clarify those changes. The SCEA is available for review at the City’s Planning Division, located at 100 Santa Rosa Avenue, Santa Rosa, California 95404, and online at the following URL: https://srcity.org/425/Plans-Studies-EIRs DECISION AND EXPLANATION REGARDING RECIRCULATION OF THE DRAFT CEQA DOCUMENT CEQA Guidelines Section 15088.5 states that new information added to a CEQA document is not significant unless the CEQA document is changed in a way that deprives the public of a meaningful opportunity to comment upon a substantial adverse effect of the project or a feasible way to mitigate or avoid such an effect (including a feasible project alternative) that the project’s proponents have declined to implement. “Significant new information” requiring recirculation includes, for example, a disclosure showing that: 1. A new significant environmental impact would result from the project or from a new mitigation measure proposed to be implemented. 2. A substantial increase in the severity of an environmental impact would result unless mitigation measures are adopted that reduce the impact to a level of insignificance. 3. A feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the significant environmental impacts of the project, but the project proponents decline to adopt it. 4. The CEQA document was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded. A complete summary of changes made to the SCEA subsequent to the public review period has been prepared and is included herein. While an exhaustive list of changes is not included here, the following provides an explanation of relevant changes to the environmental impacts analysis and the mitigation measures provided in the SCEA. December 7, 2020 Amy Nicholson, Senior Planner City of Santa Rosa Page 2 of 4 Reference: 3575 Mendocino Avenue Project – Errata Memorandum ERRATA The following revisions are minor modifications and clarifications to the SCEA and do not change the significance of any of the environmental issue conclusions within the document. The revisions are listed by resource. All additions to the text are shown underlined (underlined) and all deletions from the text are shown in strikethrough (strikethrough). Biological Resources During preparation of the Project’s Conditions of Approval for the November 12, 2020 Planning Commission hearing, it was noted that Mitigation Measure BIO-3: Sensitive Aquatic Habitat could be better worded to provide explicit clarity of temporary versus permanent impacts to Russell Creek. MM BIO-3 Sensitive Aquatic Habitat. Following the completion of construction, temporary and permanent impacts to the perennial stream (Russell Creek) shall be restored to return the impacted area to preconstruction conditions, including grading and revegetation using a local native seed mix. Permanent impacts to the perennial stream and emergent wetland shall be mitigated at a 1:1 (impact:mitigation) ratio through the purchase of wetland mitigation credits at a local mitigation bank approved by North Coast RWQCB. The revisions shown above apply to Impact BIO-2 and Impact BIO-3, discussed on pages 4-43 and 4-44 of the SCEA, respectively. Cultural Resources No comments pertaining to cultural resources were received during the public review period. However, following the Project’s Planning Commission hearing on November 12, 2020, the Federated Indians of Graton Rancheria (Tribe) expressed preference that applicable mitigation measures be modified to reflect the request for increased coordination with the Tribe as part of the CEQA process. The revisions to Mitigation Measure CUL-2: Cultural Resources Monitoring are shown below and apply to Impact CUL-2, discussed on pages 4-50 to 4-52 of the SCEA. Additionally, Mitigation Measure CUL-3: Archeological Resources, Cultural Resources Monitoring, and Tribal Cultural Resources has been added to the analysis discussed in Impact CUL-2 to further reflect the Project’s coordination with the Tribe. MM CUL-2: Cultural Resources Monitoring. Prior to any ground disturbing activities for the proposed project, a qualified archaeologist shall prepare a Cultural Resources Monitoring Plan for review by and in consultation with the affiliated tribe, and approval by the City. The Plan shall identify the type of archaeological material that could potentially be found within the project area and procedures to follow should any material be encountered during ground disturbing activities. The Plan should provide procedures and guidelines for in-field assessment of the significance of any archaeological material identified during monitoring. All ground disturbance taking place during the initial project grubbing and grading phases shall be monitored by an archaeologist or and a tribal monitor from an the appropriately affiliated tribe in order to check for the inadvertent discovery exposure of archaeological materials. The archaeologist must meet the Secretary of Interior’s Professional Qualification Standards for archaeology. The archaeologist or and tribal monitor shall be empowered to halt construction activities at the location of a discovery to review possible archaeological material and to protect the resource while the materials December 7, 2020 Amy Nicholson, Senior Planner City of Santa Rosa Page 3 of 4 Reference: 3575 Mendocino Avenue Project – Errata Memorandum are being assessed. Monitoring shall continue until, in the archaeologist’s judgment, in consultation with the tribal monitor, additional archaeological resources are not likely to be encountered. If no archaeological resources are discovered during construction, the archaeologist shall prepare a report to document negative findings after construction is complete. If an archaeological deposit is encountered during initial project grubbing or grading activities, all work within 25 60 feet of the discovery shall be redirected cease until the archaeologist or and tribal monitor can assess the find, consult with agencies and appropriately affiliated tribe(s) as appropriate, and make recommendations for the treatment of the discovery. Upon completion of the assessment, the archaeologist shall prepare a report to document the methods and results of the assessment. The final report shall be reviewed by and in consultation with the affiliated tribe, and submitted to the project applicant, City, and the Northwest Information Center. MM CUL-3: Archeological Resources, Cultural Resources Monitoring, and Tribal Cultural Resources. The Project applicant and lead agency shall engage in consultation and coordination with interested local California Native American Tribes in implementing Mitigation Measures CUL-1, CUL-2, and TRIB-1. Tribal Cultural Resources No comments were received pertaining to tribal cultural resources during the public review period. However, following the Project’s Planning Commission hearing on November 12, 2020, the Tribe expressed preference that applicable mitigation measures be modified to reflect the request for increased coordination with the Tribe as part of the CEQA process. As discussed in Impact TRIB-1 on pages 4-184 and 4-185 of the SCEA, the Project would implement Mitigation Measure CUL-2: Cultural Resources Monitoring to reduce potential impacts related to the inadvertent discovery of unknown tribal cultural resources to a less than significant level. Therefore, the revisions made to Mitigation Measure CUL-2: Cultural Resources Monitoring, shown above, would apply to the analysis presented in Impact TRIB-1. Mitigation Measure CUL-3: Archeological Resources, Cultural Resources Monitoring, and Tribal Cultural Resources would also apply to the analysis presented in Impact TRIB-1 to further require the Project’s coordination with the Tribe as it pertains to the inadvertent discovery of unknown tribal cultural resources. Minor General Revisions Minor revisions were made to the SCEA. This includes the addition of Mitigation Measure CUL-3 (Archeological Resources, Cultural Resources Monitoring, and Tribal Cultural Resources) to Table 1.13-1, Summary of Impacts and Mitigation Measures, discussed on page 1-15 of the SCEA. Additionally, the analysis presented in Impact MFS-2 on pages 4-203 and 4-204 of the SCEA, was updated to include reference to Mitigation Measure CUL-3 to reflect
