The report will be utilized by Contra Costa County during preparation of the EIR and to supplement future US Army Corps of Engineers (USACE) permitting requirements. 4. PROPOSED SCOPE OF WORK SummitWest understands that the City of Diamond Bar is requesting professional CEQA consulting services to support environmental review for the proposed 49-Unit Residential Condominium Project at 1400 Montefino Ave. The project entails the demolition of the existing commercial structures and the construction of a 49-unit development includes nine Plan 1 condominium units (4-Bedrooms at 1,929 square feet), ten Plan 2 condominium units (4-Bedrooms at 1,940 square feet), and 30 Plan 3 condominium units (3-Bedrooms at 1,966 square feet), with private drive aisles. The buildings are planned for three stories with concrete slab on grade. CEQA compliance is required due to the need for discretionary approvals, which include a tentative tract map, general plan amendment and zone change, and a conditional use permit. Currently the site is located within the Commercial Office (CO) zoning district, with an underlying General Plan land use designation of General Commercial (C) the applicant needs the land use designation to change to Medium High Density Residential (RMH) and rezone the site to Medium-High Density Residential (RMH) with a Planned Development (PD) Overlay to allow for the proposed residential development. The scope of redevelopment and potential for impacts to air quality, biological resources, cultural resources, noise, transportation, and greenhouse gas emissions necessitates formal CEQA analysis. Technical studies may include biological, air quality, greenhouse gas, cultural, noise, and energy assessments, among others. SummitWest is well-positioned to fulfill these requirements through its multidisciplinary CEQA expertise and demonstrated success managing similar entitlement-phase projects. Our team offers full-service www.SummitWestEnv.com 8 9 CITY OF DIAMOND BAR CEQA SERVICES: 49-UNIT RESIDENTIAL CONDOMINIUM PROJECT support, from biological fieldwork and cultural resource coordination to air quality modeling, ensuring a seamless and fully compliant CEQA process. We also bring strong experience coordinating noticing requirements (including AB 52 tribal consultation) and submittals to the State Clearinghouse. SummitWest’s familiarity with CEQA streamlining, agency communication, and deliverable formatting will support a defensible and efficient environmental review. WORK PLAN FOR PROPOSED SERVICES The SummitWest Team is qualified to perform all aspects of the services required by this Contract. This project will be managed by CEQA Project Manager, Mark Hopkins, ensuring task order deliverables are on time and within budget. Mark will serve as the main point of contact for the City on this Project and will be supported by our qualified biologists, cultural team and additional technical specialists as necessary. The following is a summary of the scope and services we are prepared to provide under this Contact. TASK 1: KICK-OFF MEETING A project is successful when assumptions and expectations are understood at the onset of the Project; therefore, project initiation will begin with a Kick-off Meeting via an online conference call or in-person between the SummitWest Team, City staff and the Applicant. The purpose of the Kick-off Meeting will be to discuss and finalize roles and responsibilities, data sources, data submission details, Project approach, schedule, and Project apprehension. DELIVERABLES: ● Kick off meeting agenda prior to the meeting and follow up meeting minutes ● Regular check-ins and emails TASK 2: PROJECT DESCRIPTION SummitWest is committed to providing the project with a clear and complete project description. This will include meeting with the City to obtain information necessary to provide a comprehensive project description, establish communication, and familiarize with potential issues or concerns prior to performing the CEQA analysis. Ultimately, the project description will need to be approved by the City and the Applicant. Following the approval of the project description, SummitWest will prepare the technical studies and determine the appropriate environmental documentation following adopted CEQA guidelines. DELIVERABLES: ● Clear and Complete Project Description www.SummitWestEnv.com 9 10 CITY OF DIAMOND BAR CEQA SERVICES: 49-UNIT RESIDENTIAL CONDOMINIUM PROJECT TASK 3: NATIVE AMERICAN OUTREACH AND CONSULTATION (AB 52) SummitWest will assist the City of Diamond Bar (City) with Native American consultation under AB 52. This support will begin by requesting a search of the Sacred Lands File (SLF) from the Native American Heritage Commission (NAHC) in Sacramento, California. The NAHC will also be asked to provide a list of Native American contacts for consultation under AB 52. SummitWest will then prepare draft consultation letters to the tribal groups and representatives identified by the City and/or the NAHC. The consultation letters will include a detailed project description, map of the project boundaries, a request for information on known sensitive resources within or near the project area, and an invitation to consult on the project under AB 52. The letters will be provided to the City for review and approval, and for printing on City letterhead. The City-signed letters will be sent to each tribal group. SummitWest will conduct follow-up phone calls to each contacted tribe, as needed. Any responses received will be forwarded to the City. SummitWest will document all correspondence with the NAHC and local tribal groups and representatives in a correspondence log, which will be included in the Cultural Resources Assessment Report an appendix. Upon request, SummitWest will help coordinate and participate in up to two (2) tribal consultation meetings and will prepare meeting minutes for those meetings. TASK 4: TECHNICAL STUDIES SummitWest will begin by thoroughly analyzing all existing data, including conceptual plans, the project description, traffic study, sewer study, geotechnical report, Low Impact Development (LID) report, Stormwater Pollution Prevention Plan (SWPPP) report and hydrology/hydraulic report, which is subject to the City’s peer review process. This initial analysis will establish baseline project information and identify applicable local and regional planning policies and regulations relevant to the Project site. Following this, SummitWest will evaluate whether additional data collection or targeted field surveys are necessary to complete and support environmental documentation. SummitWest has reviewed the Conceptual Plans against the initial study (IS) checklist for any technical studies and/or reports necessary or appropriate for this project. At this juncture we feel the following technical studies do not need further in depth analysis/reporting given that as per the plans, the Project is being constructed in an existing site: ● Aesthetics - The Project should conform with the City’s standards. ● Agriculture and Forestry Resources - The General Plan and Zoning will change due to the Project. However, the Project will not affect agriculture and forestry resources. ● Geology and Soils - There is evidence Project site has been previously disturbed. Furthermore, SummitWest will review the geotechnical report focusing on the discussions, conclusions, and recommendations that may need to be incorporated into the environmental document. ● Hazards and Hazardous Materials - There is evidence Project site has been previously disturbed, however, the age of the current builds may warrant asbestos protocol at time of deconstruction. www.SummitWestEnv.com 10 11 CITY OF DIAMOND BAR CEQA SERVICES: 49-UNIT RESIDENTIAL CONDOMINIUM PROJECT ● Land Use and Planning - The property is located within the Commercial Office (CO) zoning district, with an underlying General Plan land use designation of General Commercial (C). The General Plan and Zoning will change due to the Project. ● Mineral Resources - The Project will not change mineral resources. ● Population and Housing -The property is located within the Commercial Office (CO) zoning district, with an underlying General Plan land use designation of General Commercial (C). The General Plan and Zoning will change due to the Project. ● Public Services - SummitWest assumes the Developer uses Best Management Practices, such as notifying City entities and emergency response services at time of construction. ● Recreation - No existing recreational facilities are within the Project limits. ● Utilities and Service Systems - SummitWest will work with the Developer to ensure there is no conflict with any underground utilities. ● Wildfire - Wildfire risk will not change due to the Project. SummitWest is providing a scope and budget for the following technical studies below as part of the proposal. SummitWests review will include technical studies recently included as part of the General Plan 2040. TASK 4.1: AIR QUALITY AND GREENHOUSE GAS EMISSIONS STUDY The Air Quality & Greenhouse Gas Impact Assessment will include a quantitative assessment of project-generated emissions of the criteria air pollutants of primary concern (e.g., ROG, NOX, CO, PM10, and PM2.5), as well as, quantification of greenhouse gas (GHG) emissions. Operational and construction-generated emissions will be quantified using the California Emissions Estimator Model (CalEEMod). Emissions modeling will be conducted to estimate daily and annual emissions for buildout conditions, in accordance with South Coast Air Quality Management District (SCAQMD)-recommended methodologies and guidance. Emissions modeling will be conducted based on project-specific information to be provided by the project applicant, traffic data to be obtained from the traffic analysis prepared for this project, and default parameters contained in the model. Project-specific features that would help to reduce construction and or operational emissions (e.g., incorporation of solar photovoltaic systems, proximity to transit, prohibited natural gas use, etc.) will be incorporated to the extent possible. Consistency with applicable air quality plans, climate action plans, sustainable community plans, and GHG-reduction plans will be discussed. Consistency with the Diamond Bar Climate Action Plan (CAP) 2040 will be discussed. Localized air quality impacts attributable to the project are anticipated to be minor and will be qualitatively assessed utilizing SCAQMD-recommended screening methodologies. Localized odor impacts associated with the proposed project are anticipated to be minor and, therefore, will be qualitatively discussed. Dispersion modeling and the preparation of health risk assessments are not anticipated to be required and are not included. www.SummitWestEnv.com 11 12 CITY OF DIAMOND BAR CEQA SERVICES: 49-UNIT RESIDENTIAL CONDOMINIUM PROJECT Estimated construction and operational emissions will be compared to SCAQMD-recommended significance thresholds for determination of impact significance. SCAQMD-recommended and CAP-recommended best-management practices and mitigation measures will be identified and included in the report to reduce impacts found to be significant. The effectiveness of proposed mitigation measures will be quantified and included in the report. TASK 4.2: ENERGY USE IMPACT ASSESSMENT AMBIENT Air Quality & Noise Consulting will prepare an energy use impact assessment for the project. Existing energy providers in the project area and applicable regulations will be discussed. Energy use associated with the proposed project, including short-term construction and long-term operational activities will be quantified. This analysis will include fuel use associated with the use of construction-related off-road equipment and on-road vehicles, operational vehicle trips, electricity, and natural-gas use (if applicable). Energy usage associated with short-term construction activities and long-term project operations will be assessed based, in part, on data to be derived from the CalEEMod modeling conducted for this project. To the extent necessary, mitigation measures will be identified and included in the report to reduce impacts found to be significant. The effectiveness of proposed mitigation measures will be discussed. TASK 4.3: NOISE STUDY Noise & Vibration Impact Assessment The existing noise environment on and in the vicinity of the project site will be discussed, based on existing environmental documentation and onsite reconnaissance data. As part of the site reconnaissance, AMBIENT Air Quality & Noise Consulting will conduct up to ten short-term (e.g., 10-30 minute) noise measurements at various locations within the project area to document ambient noise conditions. Nearby existing noise-sensitive receptors and noise sources contributing to the ambient noise environment will be identified and discussed. Relevant background information, including noise fundamentals, descriptors, and applicable state and local regulatory framework, will be described. To assess potential short-term noise impacts, sensitive receptors and their relative exposure (considering topographic barriers and distance) will be identified. Noise levels of specific construction activities and operational equipment will be discussed and resultant noise levels at nearby receptors will be calculated. Long-term changes in operational noise levels, including stationary and mobile-source noise levels, will be quantitatively assessed. Traffic noise levels will be quantified using the FHWA’s Traffic Noise Model. Onsite noise generated by stationary and area sources (e.g., air conditioning units, parking lots, etc.) will be quantitatively assessed based on project-specific information and/or representative noise levels obtained from similar sources. Predicted changes in traffic noise levels attributable to the proposed project will be quantified and summarized in the report. The compatibility of the proposed land use will be assessed in comparison to the City of Diamond Bar’s General Plan noise standards for land use compatibility. www.SummitWestEnv.com 12 13 CITY OF DIAMOND BAR CEQA SERVICES: 49-UNIT RESIDENTIAL CONDOMINIUM PROJECT Groundborne vibration impacts associated with short-term construction activities will be quantitatively assessed. Groundborne vibration levels associated with long-term operation of the project are anticipated to be minor and will be qualitatively assessed. The significance of noise impacts will be determined in comparison to applicable City noise standards. The significance of groundborne vibration impacts will be evaluated in comparison to commonly applied vibration criteria, including criteria recommended by state and federal agencies. Mitigation measures will be developed for significant impacts. The effectiveness of proposed mitigation measures will be quantified and included in the report. TASK 4.4: BIOLOGICAL RESOURCES MEMORANDUM Literature Review and Ground Truthing Survey Prior to conducting fieldwork, SummitWest will perform a desktop analysis of the project areas using A Manual of California Vegetation (Sawyer et al), California Natural Diversity Database (CNDDB), the California Native Plant Society (CNPS) database, and other sources, as needed. The analysis will focus on historical observations of special status species within the vicinity of the project area by conducting a desktop 3-mile search. The analysis will be used to obtain baseline project information and compile lists of special status species and their suitable habitat that occur or potentially occur in the survey area as well as identify local or regional plans, policies, and regulations that may apply to the Project area. Results of this review will direct the scope and details of the field surveys to target certain species and their suitable habitat. If species requiring protocol-level surveys are found to be present during field assessments, follow-up surveys and a cost adjustment may become necessary. TASK 4.5: CULTURAL RESOURCES STUDY AND TRIBAL CONSULTATION SUPPORT The cultural resources study will include a records search and literature review, archaeological field survey, and the methods and findings of the study will be included in a Cultural Resources Assessment Report. SummitWest will also provide Native American consultation support in compliance with Assembly Bill (AB) 52. A summary of the consultation methods and results will also be included in the Cultural Resources Assessment Report. The approach for each task is described below. Cultural Resources Study Records Search and Literature Review SummitWest will conduct a cultural resources records search at the South Central Coastal Information Center (SCCIC) at California State University, Fullerton in Fullerton, California. The SCCIC serves as the repository for cultural resources records for Los Angeles County and is part of the California Historical Resources Information System (CHRIS). The records search will identify the locations of previously www.SummitWestEnv.com 13 14 CITY OF DIAMOND BAR CEQA SERVICES: 49-UNIT RESIDENTIAL CONDOMINIUM PROJECT recorded cultural resources and investigations within the project area and a 0.5-mile radius around the project boundaries. To supplement the SCCIC data, the on-line Built Environment Resources Directory (BERD) will be reviewed to identify any resources listed or determined eligible for listing on the National REgister of HIstoric Places (NRHP) and the California Register of Historical Resources (CRHR) within or near the project area. Historic maps and aerial photographs will be examined to assess the potential for historic-age features to exist within the project area.  Archaeological Field Survey SummitWest will perform an archaeological pedestrian survey of the 1.86-acre project area. All unpaved, undeveloped portions of the project area will be closely inspected for evidence of precontact and historic-age (i.e., 50 years old or older) archaeological materials using transects spaced no more than 15 meters apart. Any identified archaeological sites will be mapped, and recorded in detail. Overview photographs of the project area and all identified resources will be taken from multiple angles, and modern disturbances, such as grading and refuse, will be noted. Cultural Resources Assessment Report The SummitWest Team will prepare a comprehensive Cultural Resources Assessment Report. The report will document the methods and results of the records search and literature review, archaeological field survey, and AB 52 consultation efforts. The report will include a summary of the project description, regulatory requirements, environmental setting, and cultural context of the area, including historic, ethnographic, and precontact background. Any identified resources within the project area will be described in detail. The report will include a buried site sensitivity analysis to assess the potential of the project area to contain unknown buried archaeological resources. Potential impacts to cultural resources will be assessed and the report will provide feasible and appropriate mitigation recommendations to avoid or lessen significant impacts, if necessary. The SummitWest Team will respond to one round of consolidated comments on the report. DELIVERABLES: ● Administrative Draft ● Final/Public Draft of technical studies TASK 5: PREPARATION OF DRAFT AND FINAL CEQA DOCUMENTS The CEQA project will be initiated with a clear and complete project description, which has been approved by the City and Applicant. Following the approval of the project description, SummitWest will prepare sections of the Initial Study (IS) with the goal of a Mitigated Negative Declaration (MND) following the adopted CEQA guidelines by the City. www.SummitWestEnv.com 14 15 CITY OF DIAMOND BAR CEQA SERVICES: 49-UNIT RESIDENTIAL CONDOMINIUM PROJECT ADMINISTRATIVE DRAFT IS/MND AND DRAFT MITIGATION MONITORING AND REPORTING PLAN (MMRP) SummitWest will rely upon the findings from the provided documentation and technical studies paired with the completed IS to determine the appropriate document to comply with all CEQA requirements. Currently, the SummitWest team is anticipating the appropriate documentation to be an IS/MND. The SummitWest team will prepare an administrative draft IS/MND and draft MMRP, which will address all the environmental factors identified in Appendix G of the CEQA Guidelines, identify potentially significant impacts, and propose appropriate measures to mitigate significant impacts as necessary. After comments on the administrative Draft IS/MND and draft MMRP have been received, all comments will be incorporated and track changes will be provided. After receipt of the City comments, SummitWest will incorporate the comments and finalize the IS/MND for public review. PUBLIC NOTICES AND DISTRIBUTION SummitWest will support the City with preparation of applicable notices for distribution of the Draft IS/MND. We have assumed the Draft IS/MND will be submitted to the State Clearinghouse and that SummitWest will prepare and submit the Notice of Intent (NOI) along with the Draft IS/MND to the State Clearinghouse via CEQA Submit to start the 30-day public review period. SummitWest will support the City on document distribution, such as the local area library, the City website, with the County Clerk, if applicable, and in the local newspaper of general circulation, per Section 21092 of the CEQA statutes. This scope assumes SummitWest will work with the City to develop the mailing list and distribute the NOI and/or draft IS/MND as part of the circulation of the public notice. At minimum, the mailing list would include (a) all organizations and individuals that have previously requested notice for this Project and (b) all property owners and occupants of contiguous properties. FINAL IS/MND AND MMRP Once the 30-day comment period is completed SummitWest will revise the Draft IS/MND, as needed, based on comments received. SummitWest assumes no more than ten (10) individual comments will be received during the public review process. SummitWest will prepare the Final MMRP with the Final IS/MND inclusive of all comment letters and corresponding responses, and, if applicable, a discussion of any edits made to the document as a result of public review. After receipt of City comments on the Administrative Final IS/MND, SummitWest will revise and update the Final IS/MND.

We have assumed the habitat assessment survey will strictly cover the project area estimated up to 3.93 acres. If a larger area is required, a scope and budget adjustment will be necessary. No assumptions can be made about the status of natural resources outside of the assigned survey areas. Client will provide all relevant documentation inclusive of the footprint of the official project area. Survey time estimates are based on an assumption that roads are reasonably accessible. If roads become impassable, a cost or scope adjustment will be necessary. SummitWest will anticipate attendance of up to two (2) public hearings, two (2) additional meetings, one (1) kick off meeting, and a minimum of three (3) conference/video calls with the City. We assume that no more than ten (10) individual comments will be received. Additional comments may require a scope and budget adjustment. SummitWest will prepare the Notice of Determination and will pay any necessary filing fees. If requested by the City, one (1) SummitWest staff member from this project will attend up to two (1) public meeting in person. SummitWest will prepare the distribution list and distribute the Notice of Intent (NOI) per the City guidelines. SummitWest can submit the Draft IS/MND to the State Clearinghouse with the City's authorization. SummitWest has assumed up to $300.00 of printing and mailing costs for both the draft and final environmental documents. SummitWest will respond to a maximum of three (3) rounds of review by the City on the Administrative Draft and/or Final IS/MND. Mileage will be charged at the current IRS rate. We have assumed up to 2,637 miles at the $0.70/mi rate. If once prepared, the report/environmental documents dictates that additional technical reports and/or documentation (ie Mitigated Negative Declaration, a Supplemental or Subsequent EIR or a Project EIR) are needed, an additional scope and budget will be required to conduct the subsequent technical reports and/or documentations. We have assumed that there are no jurisdictional waters present within the project area. If the preliminary analysis results show significant findings, a jurisdictional delineation can be conducted with an updated scope and budget. We have assumed the CEQA MND Fees will not exceed $3,018.75. NWIC fees for the cultural resources records search will not exceed $1,500.00. We assume that no archaeological sites will be encountered within the project area. The scope of work includes documentation and evaluation of no more than two (2) historic-age buildings and preparation of no more than two (2) DPR 523 records. We assume that neither historic-age building will be found eligible for the NRHP or CRHR and there will be no impacts to historical resources and no development of mitigation measures. A review of historic aerial imagery indicates the existing building present within the Project Area was constructed between 1985 and 1988 and therefore does meet the age threshold for a historic-age building (45-years old or older). AB 52 consultation will include outreach to no more than eight (8) tribal groups and participation in no more than two (2) virtual meetings. One round of revisions to technical reports and DPR 523 records is assumed, if necessary.
