MEMORANDUM
TO: Wooi See, GH PacVest FROM:

Bernhard Warzecha, WRA, Senior
Environmental Permitting Specialist
CC: Jason Laub, Bay West
Development
Leslie Lazarotti, WRA, Principal-in-Charge
DATE: February 22, 2024
SUBJECT:

Dublin 580 Fallon East: CEQA Bio Mitigation Measures Status and Implementation Plan
Project Overview
GH PacVest (Applicant) is proposing the Dublin Fallon 580 Project (project), a mixed-use development located on a 192-acre site in the City of Dublin, Alameda County, California. The proposed project involves conversion of an undeveloped property into commercial, residential, and recreational land uses intermixed with open space.

The project is located immediately northeast of the Fallon Road/Interstate 580 (I-580) Interchange within Planning Subareas D (Fallon Gateway) and E (Fallon Village Center) of the 1994 Eastern Dublin Specific Plan (EDSP) and within the Fallon Village Stage 1 Planned Development (PD) study area. The property is zoned General Commercial/Campus Office (GC/CO), Open Space (OS), Community Park (CP), Public/Semi-Public (P/SP), and Medium High Density Residential (MH) as delineated in the 1985 City of Dublin General Plan, the EDSP, and the approved Stage 1 PD. The project will develop the property consistent with these plans, but deed restrictions proposed within portions of GC/CO, and all Nature Park land will increase aquatic resource protection and prohibit development over 50.08 acres. The project will also initiate the construction of the Dublin Boulevard extension, a regional transportation improvement, and will widen the portion of Fallon Road abutting the project site to the west in association with the Dublin Boulevard extension.

Purpose of the Memorandum
This memorandum provides information requested by the City of Dublin (City) related to compliance with Biological Resources Mitigation Measures (MMs) needed for California Environmental Quality Act (CEQA) review for the Dublin Fallon 580 Project (Project). Specifically, this memorandum focuses on MMs flagged by the City for Project compliance review based on the following CEQA documents:
x Environmental Impact Report [for the] Eastern Dublin General Plan Amendment and Specific Plan (Eastern Dublin EIR; Wallace Roberts & Todd 1992) 1420
WRA, Inc. | 2169 G East Francisco Blvd., San Rafael, CA 94901 www.wra-ca.com · ph: 415.454.8868
2 x East Dublin Properties Stage 1 Development Plan and Annexation Revised Draft Supplemental Environmental Impact Report (2002 SEIR; City of Dublin 2002) x Fallon Village Draft Supplemental Environmental Impact Report (Fallon Village SEIR; Haag, 2005)
Additionally, this memorandum is also intended to satisfy the 2002 SEIR MM SM-BIO-1 requiring a “Resource Management Plan”. The Resource Management Plan for East Dublin Properties (RMP) was prepared in 2004, and includes the Project site. The Applicant’s planned implementation of the MMs as presented in this memo will be consistent with the applicable measures of the RMP, however implementation will be updated as appropriate to the more recent and specific MMs developed since publication of the RMP, listed below.

As required in SM-BI-1, this memo addresses applicable mitigation measures for the development of the proposed Project on the project site. This memorandum includes information regarding specific off-site mitigation lands and the status and implementation of specific Mitigation Measures identified below. We understand that the City’s CEQA consultant may use the information contained in this memorandum, and information provided by the Applicant team, as part of its evaluation of the Project’s compliance with applicable Eastern Dublin General Plan Amendment and Specific Plan biological resources policies.

The City-flagged MMs are addressed as follows:

SM0F
1 -BIO-4: If a special-status plant species cannot be avoided, then the area containing the plant species must be measured and one of the following steps must be taken to ensure replacement on a 1:1 ratio (by acreage):
a) Permanently preserve, through use of a conservation easement or other similar method, an equal amount of acreage either within the Project area or off-site that contains the plant; or
b) Harvest seeds from the plants to be lost or use seeds from another source within the Trivalley area and seed an equal amount of area suitable for growing the plant either within the Project area or off-site. Such area shall be preserved and protected in perpetuity. If the plants fail to establish after a five-year period, then step “a” above must be implemented.

Prior to submittal of a Stage 2 development plan or tentative map, the developer shall submit a written report to the City for its review and approval demonstrating how the developer will comply with this mitigation measure, including the steps it will take to ensure that transplanting or seeding will be successful.

AND
SSM1F
2 -BIO-1 (revised). If special-status plants cannot be avoided, then the area containing the plant that is to be impacted, and the approximate number of plants to be impacted, must be determined, and the following steps must be taken:
1 SM refers to mitigation measures from the 2002 SEIR
2 SSM refers to mitigation measures from the Fallon Village SEIR. 1421
WRA, Inc. | 2169 G East Francisco Blvd., San Rafael, CA 94901 www.wra-ca.com · ph: 415.454.8868
3 a) Harvest seeds from the plants to be lost, or use seeds from another source within the Livermore and Amador valleys, and their surrounding watersheds, and seed an area suitable for supporting the plant, either within the Project area or off-site, at a level sufficient to replace the impacted individuals at a 1:1 ratio on an individual plant and basis, and at a ratio no less than 0.5:1 on an occupied habitat basis. The mitigation site shall be preserved and protected in perpetuity. If the mitigation site fails to support at least as many plants as were impacted within a five-year period, then step "b" below must be implemented.
b) Permanently preserve, through use of a conservation easement or other similar method, an equal amount of acreage either within the Project area or off-site that contains the plant.

Prior to submission of a Stage 2 development plan or tentative map, the developer shall submit a written report to the City for its review and approval demonstrating how the developer will comply with this mitigation measure, including the steps it will take to ensure that transplanting or seeding will be successful.

Implementation Status and Plan: The Applicant has completed several special-status plant surveys2F
3 and identified and mapped sensitive plant populations on the Project site required to be addressed under CEQA.3F
4 Most of these populations occur within the proposed Project grading footprint and cannot be avoided. Consistent with the Eastern Alameda County Conservation Strategy (EACCS) the Applicant will prepare and implement a Mitigation Plan consistent with the requirements of SM-BIO-4 and SSM-BIO-1. Mitigation will consist of a combination of the following: preservation of on-site and/or off-site mitigation in perpetuity, and/or seed harvest (ideally from the populations on site), with subsequent establishment of an equal area for each population at a 1:1 ratio on an individual plant and basis, and at a ratio no less than 0.5:1 on an occupied habitat basis within 5 years, preserved in perpetuity.

On-site mitigation opportunities may include deed-restricted and preserved creek, wetland and upland habitat potentially suitable to establish populations of the rare plants impacted by the Project.

Potential off-site mitigation would include compensatory mitigation on parcels within the same regional watershed owned by the City of Livermore, and the purchase of mitigation credits from the N3 Ranch mitigation bank or other agency-approved alternative mitigation bank or turnkey mitigation site. The N3 Ranch is an approximately 50,000-ac private property located south of the City of Livermore in Alameda, San Joaquin, Santa Clara, and Stanislaus counties. It is a suitable mitigation site for mitigating the Project’s impacts to jurisdictional waters of the U.S and State, as well as a location for species-specific mitigation.

A Mitigation Plan is being prepared as part of the Resource Agency permit applications, and the East Alameda County Conservation Strategy (EACCS) performance standards will be 3 Olberding Environmental, Inc.

4 implemented, including those specific to impacts to special-status plants as outlined in Chapter 3 of the EACCS:
- Avoidance of direct and indirect impacts to the extent feasible - Minimization of unavoidable impacts through appropriate design and construction measures - Mitigation of residual impacts through on-site or off-site preservation, enhancement, restoration, or creation of suitable habitat
- Monitoring and adaptive management of mitigation sites to ensure long-term viability and functionality
The Mitigation Plan, once approved by the regulatory agencies will be submitted to the City for informational and record-keeping purposes.

SM-BIO-5: To the extent feasible, implementation of the Project through subsequent preparation of Stage 2 development proposals on a property-by-property basis shall be designed to avoid and minimize adverse effects to waters of the United States (which include seasonal wetlands and intermittent streams) within the Project area. Examples of avoidance and minimization include (1) reducing the size of future individual development projects within the Project area, (2) design future development projects within the Project area so as to avoid and/or minimize impacts to waters of the United States, and (3) establish and maintain wetland or upland vegetated buffers to protect open water such as streams. In order to protect the particularly sensitive Arroyo willow riparian woodland and red-legged frog habitat found in the Fallon Road drainage from Fallon Road upstream to its terminus, future development projects within the Project area either shall completely avoid this drainage or limit impacts to bridge crossings (as opposed to fill) or other such minimally impacting features.

Implementation Status and Plan: The Project has been designed to avoid and minimize adverse effects to waters of the United States to the extent feasible. Specifically, the size of the Project grading footprint has been reduced to allow for deed-restricted preservation of 10.4± acres (1,840± linear feet) of waters and wetlands, including streams, and associated riparian habitat and upland buffers. These avoidance areas include avoidance of the riparian woodland lining the drainage in the northwest corner of the property, along Fallon Road. The Project includes preservation of on-site willow riparian woodland occurring on the northwest corner of the property and widening and daylighting of portions of the downstream reaches of the perennial stream along Fallon Road, a portion of which currently flow through closed culvert pipes. A creek enhancement and mitigation design plan has been prepared by ENGEO (Attachment A).

Additionally, the Project will obtain authorization from the USACE, RWQCB, CDFW, and USFWS as applicable. The permitting programs administered by these agencies (including compliance with CFGC 1602 and 2081, the Clean Water Act, Porter Cologne Water Quality Control Act, and State and Federal Endangered Species Acts) will require the Project to avoid, minimize and compensate for potential impacts to all aquatic resources and special-status species and their habitats, including California red-legged frog. With implementation of the agency-required avoidance, minimization and compensatory mitigation measures for this project, the requirements of SM-BIO-5 will be achieved concurrently. Additionally, project and mitigation implementation will be consistent with the requirements developed for the EACCS to protect streams, riparian and CRLF habitat.

SM-BIO-6: To the extent that avoidance and minimization are not feasible and wetlands, intermittent streams or other waters will be filled, such impacts shall be mitigated at a 2:1 ratio 1423
WRA, Inc. | 2169 G East Francisco Blvd., San Rafael, CA 94901 www.wra-ca.com · ph: 415.454.8868
5 (measured by acreage) within the Project area if feasible, through the creation, restoration or enhancement of wetlands, intermittent streams or other waters. Such mitigation area shall be preserved and protected in perpetuity. Prior to submittal of a Stage 2 development plan or tentative map for any property within the Project area, the property owner shall submit a written report to the City for its review and approval demonstrating how the owner will comply with this mitigation measure.

AND
SM-BIO-7: If mitigation within the Project area is not feasible, then the developer shall mitigate the fill of wetlands or other waters at a 2:1 ratio (measured by acreage) at an off-site location acceptable to the City. Such mitigation area shall be preserved and protected in perpetuity. Prior to submittal of a Stage 2 development plan or tentative map, the property owner shall submit a written report to the City for its review and approval demonstrating how the owner will comply with this mitigation measure.

Implementation Status and Plan: The Applicant proposes to mitigate unavoidable impacts to creeks and wetlands at a minimum ratio of 2:1 (measures by acre). This will be achieved by a combination of on-site creation/preservation, in combination with compensatory mitigation on parcels within the same regional watershed owned by the City of Livermore, and obtaining credits from N3 Ranch mitigation or other agency-approved alternative mitigation bank or turnkey mitigation site.

Additionally, project and mitigation implementation will be consistent with the requirements developed for the EACCS to protect and mitigate impacts to wetlands, intermittent streams and other waters. EACCS mitigation measures related to wetlands, intermittent streams and other waters are designed to protect and enhance the ecological functions and values of these aquatic resources. The EACCS provides a framework for identifying, implementing, and monitoring mitigation projects that compensate for the unavoidable impacts of development activities on wetlands, intermittent streams and other waters within the EACCS planning area.

Consistent with the EACCS, the Project’s mitigation will establish performance standards and success criteria:
- Mitigation projects will be located within the same regional watershed - Mitigation projects will be compatible with the existing and planned land uses, and avoid or minimize conflicts with agricultural operations, public utilities, flood control, fire management and other public services.

The Mitigation Plan, once approved by the regulatory agencies will be submitted to the City for informational and record-keeping purposes.

Additionally, the Project will obtain authorization from the USACE, RWQCB, CDFW, and USFWS.

The permitting programs administered by these agencies (including compliance with CFGC 1602 and 2081, the Clean Water Act, Porter Cologne Water Quality Control Act, state and federal Endangered Species Acts) will require the Project compensate for potential impacts to all aquatic resources in-kind, and are expected to require compensatory mitigation for loss of aquatic resources at a ratio of 2:1 or higher. Therefore, with implementation of the agency1424 WRA, Inc. | 2169 G East Francisco Blvd., San Rafael, CA 94901 www.wra-ca.com · ph: 415.454.8868
6 required compensatory mitigation measures for this project, the requirements of this SM-BIO-6 and 7 will be achieved concurrently.

SM-BIO-14: If avoidance is infeasible, then mitigation lands providing similar or better habitat for CRLF at a 3:1 replacement ratio or suitable ratio determined by the USFWS, shall be preserved and protected in perpetuity. This mitigation, to be proposed in a mitigation and monitoring plan submitted to the City, shall be required prior to submittal of the Stage 2 Development Plans and tentative maps for any specific property within the Project area. In selecting off-site mitigation lands, preference shall be given to preserving large blocks of habitat rather than many small parcels, linking preserved areas to existing open space and other high-quality habitat, and excluding or limiting public use within preserved areas. If the identified mitigation lands have been approved by the City, the following guidelines [outlined in SM-BIO-15] implemented prior to and during construction would reduce impacts to individual CRLF and preserved CRLF habitat.

Implementation Status and Plan: The Applicant will mitigate unavoidable impacts to CRLF habitat at a 3:1 replacement ratio or suitable ratio determined by the USFWS through the Section 7 consultation process. The Applicant has submitted a CWA Section 404 permit application, which requires consultation with USFWS defining the adequate compensatory mitigation ratio, acceptable mitigation lands and/or mitigation credits, as well as avoidance and minimization measures to minimize incidental take of this species. This process will include preparation of a mitigation and monitoring plan element, which will also be provided to the City for informational and record-keeping purposes once approved by the regulatory agencies.

Specifically, restoration of Jordan Creek (Attachment A) and adjacent wetland avoidance will increase quality and quantity of CRLF habitat on-site. Both on-site and off-site mitigation for CRLF will be consistent with the EACCS, including, but not limited to:
- Minimizing indirect impacts to CRLF and its habitat by implementing all required Avoidance and Minimization Measures (AMMs), best management practices such as erosion control, fencing, lighting, noise reduction, and invasive species management. - Compensating for unavoidable impacts to CRLF and its habitat by providing habitat restoration, enhancement, creation, or preservation following the EACCS Impact/Mitigation Scoring for California red-legged frog in the EACCS Study Area (Appendix E, Table E-5.).
- Monitoring and reporting on the effectiveness of the mitigation measures and the status of the CRLF population and habitat.

With implementation of all measures required by the USFWS/Corps through ESA Section 7 consultation for CRLF, and consistency with the EACCS, the requirements of SM-BIO-14 will be achieved concurrently.

SM-BIO-19: If avoidance is infeasible, mitigation lands, providing similar or better aquatic and upland habitat for California tiger salamander (CTS) at a 1:1 ratio shall be set aside in perpetuity.

Upland habitat shall be mitigated by preserving upland on-site, or if necessary, by preserving currently occupied upland tiger salamander habitat off-site. Aquatic habitat shall be mitigated by creating an equal number (or acreage) of new aquatic California tiger salamander breeding areas within the preserved upland habitat. This mitigation, included in a mitigation and monitoring plan, shall be submitted to the City prior to submittal of Stage 2 development plans and tentative maps. In selecting off-site mitigation lands, preference shall be given to preserving large blocks of 1425
WRA, Inc. | 2169 G East Francisco Blvd., San Rafael, CA 94901 www.wra-ca.com · ph: 415.454.8868
7 habitat rather than many small parcels, linking preserved areas to existing open space and other high-quality habitat, and excluding or limiting public use within preserved areas.

Implementation Status and Plan: The Applicant will mitigate unavoidable impacts to CTS habitat at a 1:1 replacement ratio by preserving upland on-site, or if necessary, by preserving currently occupied upland tiger salamander habitat off-site. Aquatic habitat will be mitigated by creating an equal number (or acreage) of new aquatic California tiger salamander breeding areas within the preserved upland habitat, if feasible. Mitigation will be consistent with the EACCS, specifically as stated in Table E-4. Impact/Mitigation Scoring for California tiger salamander in the EACCS study area.

Additionally, the Applicant has submitted a CWA Section 404 permit application, which requires consultation with USFWS defining the adequate compensatory habitat mitigation ratio, acceptable mitigation lands and/or mitigation credits, as well as avoidance and minimization measures to minimize incidental take of this species. Additionally, the Applicant will obtain an Incidental Take Permit from CDFW, which furthermore will define adequate compensatory mitigation. This process will include preparation of a mitigation and monitoring plan element, which will also be provided to the City for informational and record-keeping purposes once approved by the regulatory agencies.

With implementation of all measures required by the USFWS/Corps through ESA Section 7 consultation, and California Fish and Game Code Section 2081 et seq., the requirements of MM SM-BIO-19 will be achieved concurrently.

SSM-BIO-2 (revised) (burrowing owl). During the breeding season (February 1-August 31) prior to submittal of Stage 2 development proposals for a particular parcel, or during a subsequent breeding season but prior to the initiation of construction, a survey shall be conducted according to CDFG protocols to determine whether Burrowing Owls are present, and if present, the number of nesting pairs of Burrowing Owls present on the parcel.

Implementation Status and Plan: Available documentation, including CDFW’s CNDDB, the Biological Resources Analysis Report for the Dublin Fallon East Property (Olberding Environmental 2022) and unpublished results from site visits by other biologists over the past years (including Johnson Marigot Consulting), indicates that the site has not been occupied since 2002.

Additionally, the Applicant has retained WRA to assessing the site for burrowing owl presence or absence by Conducting burrowing owl surveys in 2024 according to the latest CDFW survey protocol defined in the 2012 CDFW Staff Report on Burrowing Owl Mitigation. The results will be submitted to the City for review. If a burrowing owl is found to occupy the Project site, the Applicant will coordinate with CDFW to develop an adequate Burrowing Owl Mitigation Plan, and/or implement related MMs SSM-BIO-3 through SSM-BIO-5. Additionally, burrowing owl is a focal species of the EACCS. Therefore, the Project will implement applicable mitigation measures related to this species.

Dublin Fallon 580 Trip Generation Comparison Memorandum 1521
Kittelson & Associates, Inc.

Technical Memorandum
This technical memorandum presents the vehicle trip generation for the proposed development of the Dublin Fallon 580 project located north of I-580 in Dublin, California. Development of this property and its impact on the transportation system have been studied in previous Environmental Impact Reports (EIRs) in 1992, 2002, and 2005 – this technical memorandum is intended to provide a comparison between the trip generation assumed in the 2005 SEIR1 document with the 2023 proposed development plan.

Dublin Fallon 580 Property
The property is located on an approximately 192-acre site designated as Medium High Density Residential (13.5 acres), General Commercial/Campus Office ([GC/CO], 126.3 acres), Community Park (35.8 acres), Open Space (44.9 acres) and Public/SemiǦPublic (2.5 acres). The project site is located in the eastern portion of Dublin (Assessor’s Parcel Numbers [APN]: 905-0001-006-03; 985-0027-002; 985-0027-005; 985-0027- 004). The project is located east of Fallon Road and north of Interstate 580 (I-580). Croak Road divides the project site from north to south and the future Dublin Boulevard Extension Project bisects the project site from west to east.
2005 SEIR Assumptions
Based on the existing approved stage 1 PD and Eastern Dublin Specific Plan, the project would develop

13.5 acres as 200 residential units and about 126 acres would become 1,446,000 square feet of general commercial/campus office. Since general commercial and campus office have different trip generating rates, the 1,446,000 square feet was divided into the component land uses.

Determination of the component land uses was based on the traffic study2 completed for the 2005 SEIR.

This traffic study assumed two types of land uses for the non-residential components of the project including retail and office. To split the 1,446,000 square feet into retail and service components, Kittelson used the same ratio as the overall Fallon Village Supplemental EIR trip generation table (Table 4.2.6 2005 SEIR) which shows 980,000 square feet of service and 1,522,000 square feet of retail. Therefore, the resulting square footage once the 1,446,000 square feet was proportioned was 879,621 square feet of retail and 566,379 square feet of service space.

Dublin Fallon 580 Trip Generation Comparison
Kittelson & Associates, Inc.
2023 Proposed Project
The 2023 proposed project is proposing to change the land use to the following:
x 238 multi-family dwelling units
x 2,888,400 square feet of advance manufacturing
x Hotel of approximately 314 rooms
x 100,000 square feet of retail
x 100,000 square feet of office
This is larger than the 1,446,000 square feet from the 2005 SEIR but advanced manufacturing uses are a less intensive trip generator than office and retail land uses. The residential component of the project would increase slightly by eight (8) units compared to the SEIR to a total of 238 units.

Trip Generation
Trip generation is a key factor in transportation analyses whether a level of service analysis or a vehicle miles traveled (VMT) analysis is being performed. This section compares the estimated daily trip generation for the Dublin Fallon 580 project parcels in the 2005 SEIR with what the trip generation is estimated to be with the 2023 proposed project. A 2023 proposed project trip generation that is less than the 2005 SEIR trip generation would mean the 2023 proposed project fits within the trip generation envelope of what was studied in the 2005 SEIR and no additional impacts that were not previously disclosed would be anticipated. A trip generation in 2023 higher than what was studied in the 2005 SEIR could potentially result in new impacts and would need to be studied in more detail. 2005 SEIR Trip Generation
The traffic study for the 2005 SEIR used the Institute of Transportation Engineers’ (ITE) Trip Generation Manual 7th Edition to estimate trip generation for Fallon Village. The four land use categories used and the associated daily trip generation rate from the ITE Trip Generation Manual 7th Edition include:
x Single Family Residential (ITE Code 210 with a daily rate of 9.57 trips per dwelling unit) x Multifamily Residential (ITE Code 220 with a daily rate of 6.72 trips per dwelling unit) x Retail (ITE Code 820 with a daily rate of 42.94 trips per thousand square feet) x Office/Service (ITE Code 710 with a daily rate of 11.01 trips per thousand square feet) Based on these land uses and the square footage and dwelling units assumed for the proposed project site in the 2005 SEIR, the estimated daily trip generation for the Dublin Fallon 580 project parcels is shown in Table 1. As shown, the Dublin Fallon 580 project is estimated3 to have produced 45,550 daily vehicle trips in the 2005 SEIR.
3 The exact trip generation used is unknown since these documents analyzed overall trip generation of Fallon Village 1523

2023 Proposed Project
The current 2023 proposal is more specific than the 2005 SEIR with residential units, advanced manufacturing, hotel, retail, and office land uses. To estimate the trip generation of these land uses, Kittelson used the latest version of the ITE Trip Generation Manual which is the 11th Edition. The five land use categories used and the associated daily trip generation rate from the ITE Trip Generation Manual 11th Edition include:
x Multifamily Residential (ITE Code 220 with a daily rate of 6.74 trips per dwelling unit) x Advanced Manufacturing (ITE Code 140 with a daily rate of 4.75 per thousand square feet) x Hotel (ITE Code 310 with a daily rate of 7.99 trips per room) x Retail (ITE Code 820 with a daily rate of 37.01 per thousand square feet) x Office (ITE Code 710 with a daily rate of 10.84 per thousand square feet) Table 2 shows the resulting daily trip generation which is projected to be 22,618 trips per day.

Conclusion
This technical memorandum documented the trip generation for the Dublin Fallon 580 property studied as part of the 2005 SEIR for Fallon Village and the estimated trip generation for the same property based on the 2023 development plan. As shown in Table 1 and Table 2, the 2023 development plan generates 22,932 fewer daily vehicle trips compared to the assumptions from the 2005 SEIR. This results in the 2023 development plan fitting within the envelope of what was previously studied and no new transportation impacts not previously disclosed would be anticipated based on daily trip generation of the Dublin Fallon 580 property.
