OAAC Adapt 2025 – 2026 CIP
Scope of Services
CMG is proposing to provide the following services to the City of Alameda to support ongoing design and engineering associated with OAAC Adapt Sea Level Rise Adaptation Projects.
Geomorphology and Ecological Study
Southshore, Elsie Roemer and Bay Farm Island Northshore
Purpose: Sand movement along Crown Beach, South Shore Beach, Elsie Roemer Bird Sanctuary, and within the San Leandro Bay Estuary is a key uncertainty for the implementation of nature-based strategies.
Summary: South Shore and Crown beaches are manmade features requiring ongoing annual sand management.
Understanding the natural movement of sand between the Bay and the beaches, and along the beach towards the San Leandro Bay Estuary will help inform potential natural-based pilot studies that may improve sand management and help address future sea level rise and coastal erosion. The study will leverage existing resources, including EBRPD sand management records, and include new data collection and modeling to better understand how actions such as mudflat augmentation and eelgrass restoration may reduce sediment loss and enhance sand management activities.
The study will also inform the designs along northern Bay Farm Island (BFI) and will provide sediment transport and hydrodynamic insights that may inform nature-based strategies along the San Leandro Bay shoreline.
Task 1 Project Management and Coordination
x Internal team project management and coordination
x Regular coordination and meeting attendance with the Cities of Oakland and Alameda and EBRDP (up to 5 meetings)
x Presentations to the OAAC Steering committee (up to 3 meetings). x Coordination and meeting attendance with the BFI Near-term Project, and the South Shoreline / Elsie Roemer Committee (to be developed) (up to 5 meetings, may be concurrent with meeting attendance with the Cities of Oakland and Alameda and EBRDP to maximize efficiency and conserve budget.
Assumptions:
x This task is specific to the Geomorphology and Ecology Study and is not intended to supplement or replace the project management needs for Long-term Regional Adaptation Plan (RSAP) development. x Presentations representing project progress to the OAAC Steering Committee, Design Review Team, or other groups will rely on the presentations prepared for the OAAC Project Partners. Presentations are anticipated to represent specific milestones (e,g., findings from wave modeling, hydrodynamic modeling) and results of the project.
x Meeting attendance may be limited to one staff member from either Pathways or ESA to conserve budget for the technical tasks. Additional non-current meetings would require additional scope and budget.
Deliverables:
x Up to 3 presentations to the OAAC Project Partners, OAAC Steering Committee, or a subset of the OAAC Steering Committee focused on these shoreline reaches.
Task 2: Data Gathering
CMG Landscape Architecture 6/11/2025 Page | 2
x Pathways and ESA will gather readily available information to support the modeling and analysis efforts, including bathymetry data, water levels, long-term wind data, and updated near-term topography from the most recent 2021 LiDAR.
x ESA will collect wave data for nearshore waves within the project area to inform and supplement the wave model. Wave monitoring instruments will consist of up to two sonic wave sensors in the intertidal zone to measure nearshore wave heights – likely to consist of one at Southshore / Elsie Roemer and one near the BFI Near-term Project along Bay Farms Island’s Northshore. The wave data will be post processed and made available to inform the modeling and analysis efforts.
Assumptions:
x Publicly available site conditions data has enough accuracy and resolution for the purpose of this study. x Data collected during the Subregional Adaptation Plan (Existing Conditions Memorandum) will inform and supplement the model results.
x ESA will deploy instruments for up to 8 weeks of duration to collect continuous data for comparison of wave conditions at several locations along the site.
x There are risks associated with field data collection, especially in the marine environment. ESA maintains insurance for instruments and therefore takes the risk of damage to the hardware or loss. ESA also applies quality control procedures to reduce the possibility of malfunction. However, ESA cannot guarantee that data collection will be complete. ESA will endeavor to complete the scope of work within the estimated fee and schedule with the data collected. ESA's policy is to notify clients if a problem arises and results in the need for added effort or schedule revision, so that the appropriate remedy can be identified and implemented. ESA reserves the right to not re-deploy instruments if the risk of damage or loss, especially due to theft or vandalism, appears high.
Deliverables:
x Input to summary report (Word and graphic formats anticipated) x Wave data (digital).
Task 3 Wave Modeling
x ESA will conduct wave modeling to characterize the wave climate along the South Shore / Elsie Roemer shoreline and Bay Farm Island Northshore. Results of the modeling will provide baseline data for use in the shoreline change assessment (Task 6) and for refinement of the BFI 30% design funded under a separate project.
x Model set up and simulation runs. We propose using a spectral wave model, the Simulating Waves and Nearshore (SWAN) model, to simulate and hindcast the historical wave climate near the project site. The model grid will be a subset of the grid developed for the larger hydrodynamic model in Task 4. The grid will be refined sufficiently to approximate high-level design concepts for the South Shore / Elsie Roemer shoreline and Bay Farm Island Northshore.
x Wave Hindcast. A lookup table that relates wind conditions to nearshore wave parameters will be developed based on SWAN model results. An historical wave time series will be developed using the lookup table.
x Sea level rise scenarios and design concepts. ESA will simulate existing conditions (baseline) and high- level design concepts for one extreme event and two sea level rise scenarios, consistent with the project sea level rise criteria and Tasks 4 and 5.
x The extreme event will be selected in consultation with Pathways (Task 4) and review of the historical record.
Assumptions:
x Model limitations from a standard spectrum wave model are acceptable.
CMG Landscape Architecture 6/11/2025 Page | 3
x Design concepts will be limited to simple concepts such as large woody debris groins or habitat islands at an approximate level to inform discussion. Up to two design concepts will be modeled (consistent with Task 4).
x The modeling is intended to inform a high-level shoreline change assessment that will inform the feasibility of the design concepts to protect/maintain the shoreline as sea levels rise. The modeling is not intended to replace detailed design analysis.
Deliverables:
x Sections of summary report describing input data, model setup, and model results (Word, Excel, and graphic formats anticipated)
x Draft Presentation of Wave Analysis Results (PowerPoint)
Task 4. Hydrodynamic Modeling
x Pathways will use the San Francisco Bay Delft3D Community Model developed by the USGS/Deltares and assess the natural movement of sand between the Bay and the beaches, and along the beach towards the San Leandro Bay Estuary.
x Pathways will refine the bathymetry data sets used in the Community Model and update the bathymetry used as appropriate. The adjacent nearshore and overland areas not captured in the updated bathymetry data will be updated using the 2021 LiDAR
x Pathways will refine the model grid in the vicinity of the Oakland-Alameda project area, including along Southshore Beach, Elsie Roemer March, the northern Bay Farm Shoreline, and San Leandro Bay including Arrowhead Marsh. The grid will be refined sufficiently to resolve proposed high-level design concepts intended to retain sand and limit the natural drift of sand. The design concepts will be consistent with Task 3 and 5.
x Pathways will model up to 4 multiple periods of interest, representing typical and extreme conditions, such as:
o The significant erosion events that occurred in winter 2024 and winter 2022/2023 o Typical winter conditions associated with recent El Nino winters o Typical seasonal conditions selected based on a review of EBRPD sand management records (from Task 5).
o Pathways and ESA will coordinate on the selection of events for the wave modeling (Task 4) and hydrodynamic modeling.
x Pathways will use particle tracking to inform sediment transport and the concept-level sediment budget (Task 6).
x The Delft3D simulations will inform
o The natural movement of sand between the Bay and the beaches o The potential movements of sand towards the San Leandro Bay Estuary o The shoreline change assessment (Task 5).
o How geomorphic and ecological features, such as mudflat augmentation or eelgrass restoration, may reduce sediment loss and enhance sand management activities. x How the proposed designs along South Shore / Elsie Roemer shoreline and BFI Northshore may alter sand movement and retention, which could impact nature-based solutions and/or Arrowhead Marsh in the San Leandro Bay Estuary.
Assumptions:
x Use of the calibrated and validated Community Model will limit the need for model calibration x Sand movement will be approximated using particle tracking simulations, and a full sediment transport model will not be developed.
x The SWAN modeling (Task 3) will not be coupled with the Delft3D modeling (Task 4) (i.e., wave results will be independent of hydrodynamics), although they can be coupled in a future effort if required.
CMG Landscape Architecture 6/11/2025 Page | 4
x Up to two sea level rise scenarios and up to two high-level design concepts will be modeled (consistent with Task 3 and 5).
Deliverable:
x Sections of summary report describing input data, model setup, and model results. (Word, Excel, and graphic formats anticipated).
x Draft Presentation of Hydrodynamic Modeling Results (PowerPoint)
Task 5. Shoreline Change Assessment
x ESA will provide an assessment of past and potential future shoreline (beach and dune) change at the South Shore / Elsie Roemer shoreline and Bay Farm Island Northshore. x This assessment will be informed by:
o Previous site-based geomorphic observations
o Review of shoreline change using available satellite imagery o Results of the wave data collection (Task 2), wave modeling (Task 3), and hydrodynamic modeling (Task 4)
o Estimated rates of sediment transport using established, empirical coastal engineering equations.
o A concept-level sediment budget of the Southshore and Elsie Roemer shoreline
Assumptions:
x The beach at BFI North Shore is narrow and is not well resolved in satellite imagery. Due to this lack of data, BFI Northshore area is excluded from the historic shoreline change and sediment budget analyses. x EBRPD will provide data on historic and planned sediment placement dates, locations, and volumes at the Southshore and Elsie Roemer areas. EBRPD will also provide sand management records that note when sand management has occurred each year since the last large sand placement effort was completed.
x The results will be used to inform a conceptual model of sediment transport and will be interpreted to infer the potential influence of (up to two) design interventions (e.g. large woody debris groins or habitat islands), but these effects will not be directly modeled. x The assessment will focus on existing conditions and up to two future sea level rise scenarios (consistent with Tasks 3 and 4).
x Pathways will provide current data from the hydrodynamic modeling (Task 4). x Presentation of the Shoreline Change Assessment will be included within the final presentation (Task 6)
Deliverables:
x Section of summary report describing existing and future shoreline change (Word).
Task 6. Final Report
x Pathways and ESA will prepare a final summary report documenting the results of geomorphic and ecological study (Tasks 2 – 5).
x The report will characterize the overall water level, wave climate, and sediment movement in the area, including identifying areas where existing sand placed on the South Shore beach may be lost and/or retained.
x The report will also summarize how the design concepts may impact or interrupt sediment movement in the area, documenting the potential benefits and impacts of these changes.
Assumptions:
x Two rounds of review are anticipated. One round with the Cities of Alameda, Oakland, and EBRPD, and one round with the OAAC Steering Committee (or a subset of this committee focused on these shoreline reaches).
CMG Landscape Architecture 6/11/2025 Page | 5
x Collated comments will be provided to Pathways and ESA. x No outreach materials are anticipated to be developed under this study
Deliverables:
x Draft and Final Geomorphology and Ecology Study (Word and PDF formats) x Draft and Final Presentation of Results (PowerPoint and PDF formats)
Compensation for the above services shall be provided on an hourly basis and shall not exceed the following amounts.
