Award Details Contract Award Date: Mar 02, 2022 Contract Award Number: W9123822C0008 Task/Delivery Order Number: Contractor Awarded Unique Entity ID (DUNS): 062237156 Contractor Awarded Unique Entity ID (SAM): VEXGAY93NLB7 Contractor Awarded Name: DIXON MARINE SERVICES, INC. Contractor Awarded Address: Inverness, CA 94937-9706 USA Base and All Options Value (Total Contract Value): $3647576.24 The project consists of constructing a new Wetland area, and enhancing adjacent existing degraded marshland on the Alameda Point Campus site in Alameda County, CA. The 2018 Alameda Basis of Design Report determined that the need for Onsite Wetlands Mitigation was a result of unavoidable fill to the existing wetlands in the Alameda Point area. The new wetland area will consist of both a tidal basin and tidal marsh enhancement area. Construction of the tidal basin includes, but is not limited to, excavating to basin floor, grading of channels, and constructing a riprap and aggregate connection through the seawall. In accordance with DFARS 236.204(i) the estimated magnitude of construction is expected to be between $5M and $10M. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. Completion- of approximately 1248 days. Create acres of tidal marsh that consists of mostly vegetated marsh plain with slough channels that meet USACE criteria for jurisdictional wetlands prior to the impact of the wetlands due to construction. o Use techniques that restore a self-sustainable ecosystem with minimal maintenance over a long term. o Restore a unique mix of native tidal marsh species appropriate for tidal marsh plants. o Restore grasses in the transition zone to provide high tide refuge habitat for the tidal marsh animals and foraging habitat for the birds and insects and increase the native plants. o Design restored habitats to reduce the temporary impacts and avoid permanent impacts on existing wetlands. o Allow natural formation of small marsh pond to promote habitat diversity. o Meet Region Water Quality Control Board (RWQCB) screening guidelines for sediment containment for protection of aquatic life. o Avoid impacts to the California Least Tern colony during and after construction and maintenance. o Ensure that the vegetation height does not reach above 2 feet above the existing ground to maintain the California Least Tern viewshed.
