City of Pleasanton |Stormwater System Management Plan |PWD 25.601 |PAGE 8 Wood Rodgers proposes a prioritization approach for the CIP development in Task 5. Development of a Capital Improvement Plan. The approach ranks projects based on the flood risk, improvement costs, equity benefits, and traffic interruption. This strategy aims to maximize flood control benefits within the constraints of limited public agency resources. Wood Rodgers will identify, optimize, and rank improvement projects for cost‐effectiveness using flood risks developed with the FEMA Hazus program, and perform cost‐benefit analysis. In addition to cost‐effectiveness, Wood Rodgers proposes incorporating equity benefits into improvement project prioritization. Prioritizing projects with equity considerations promotes fair resource allocation, enhances social cohesion, garners public support, ensures legal compliance, and fosters long‐term economic benefits. This approach also positions the City for successful FEMA grant funding applications that offer a 90% federal fund contribution for capital project implementation within disadvantaged communities. Traffic interruption represents another form of economic impact that will be used to rank improvement projects. The metric commonly used and accepted by FEMA in grant applications to quantify traffic interruption is Average Daily Traffic (ADT) counts. Wood Rodgers will also consider environmental permitting requirements, rights‐of‐way, encroachment permits, and utility conflicts when evaluating the already prioritized projects. The ranking and implementation requirements for each project will then be used to develop a CIP implementation schedule. Water quality regulatory compliance has stretched the City’s financial and maintenance resources. Trash capture devices, hydromodification systems, and other green infrastructure have been planned and constructed to be in compliance with the NPDES MS4 Permit. However, there is still synergy to integrate the water quality enrichment green infrastructure with storm drainage facilities to assess the flood reduction benefits and combine both the water quality and flood mitigation funding opportunities. In Task 3.3. Regional GI Modeling (Optional), Wood Rodgers proposes to integrate regional stormwater capture facilities to storm drainage facilities to combine and reduce improvement extents. Without a reliable and sufficient funding mechanism, the City’s much‐needed maintenance, rehabilitation, and improvements could be delayed, and the City could be forced to adopt a reactive approach. The Wood Rodgers Team’s experience in identifying needs, developing a funding mechanism, and applying for grant applications will be instrumental in implementing a healthy and sustainable funding program for the City. Wood Rodgers’ recent success in applying for grant funding, totaling more than $70M, will provide much‐needed relief to the financial burden of the City. Wood Rodgers proposes to leverage our experience to identify and develop technical information as the basis for future grant applications in Task 10.7. Grant Funding Opportunity. The Alameda County Flood Control and Water Conservation District (ACFCD), also known as Western Alameda County, has been maintaining Alameda Creek to provide flood protection for the densely populated areas in the cities of Union City and Fremont. One of their objectives is to limit the flow discharged from upstream drainage facilities to the design capacity of Alameda Creek. The upstream regional drainage facilities are owned and maintained by Zone 7, which serves Eastern Alameda County. One of Zone 7’s primary goals is to prevent flooding along its regional facilities, which are mostly designed to accommodate a 100‐year storm event. While local municipalities benefit from the flood protection offered by these regional facilities, they also prioritize the maintenance and flood resiliency of their local drainage systems, typically designed for a 10‐year storm event. The key to the success of this project is aligning stakeholder priorities and objectives. Wood Rodgers’ knowledge and experience—developed during the development of the Alameda County Hydrology and Hydraulics Manual—and our extensive work reviewing and calibrating Zone 7’s HEC‐HMS and HEC‐ RAS models through our on‐call contract, give us the local knowledge necessary to meet the objectives of multiple agencies. To achieve these objectives, Wood Rodgers will integrate all existing models to create a master model for use by ACFCD, Zone 7, and the City; calibrate the master model using both small and large historical storm events for accurate assessment of maintenance and flood control needs; and append detailed drainage facilities and street networks to enable local flood risk assessment and improvement analysis. With the understanding of the City’s issues, the Wood Rodgers Team has formulated the following tasks to address the issues as discussed above.
