Description
Background
This RFQ seeks a design consultant for the Chambers Creek Dam Removal and Estuary Bank and Channel Protection Project, issued by Pierce County. The project aims to remove the Chambers Creek Dam and implement restoration measures for the estuary, focusing on improving salmon habitats and addressing environmental pollution. The dam, built in 1933, has been deemed a barrier to fish passage and detrimental to local ecosystems. Its removal is crucial for salmon recovery in Water Resource Inventory Area (WRIA) 12, as it will restore natural flow regimes and enhance habitat complexity.
Work Details
The consultant will be responsible for designing 30% to 100% design plans that include:
1. **Dam Removal Design**: Staging and construction sequencing plans, hydraulic analysis during demolition phases, right-of-way agreements for necessary building demolitions, and overall project management.
2. **Habitat Restoration**: Grading, bank protection, and large wood design within the dam footprint to improve habitat function.
3. **Coordination with Chambers Bay Tech Team**: Confirming fish passage approaches, water quality monitoring during construction, and construction methods for dam removal.
4. **Data Collection**: Bathymetric data collection to support hydraulic modeling and sediment transport analysis.
5. **Modeling Updates**: Hydrodynamic modeling to inform design refinements regarding flooding and sediment transport.
6. **Design Refinements**: Adjustments based on updated modeling results for habitat design including large wood placement locations.
7. **Pedestrian Enhancements**: Improvements for pedestrian crossings and roadway illumination to enhance access to the Chambers Creek Canyon trail system.
8. **Environmental Permitting**: Development of necessary environmental permitting application materials.
Period of Performance
The initial contract period is anticipated to be 24 months from the date of contract execution, with an option for renewal for an additional three years.
Place of Performance
The project will take place in Pierce County, Washington, specifically around the Chambers Creek area.
Bidder Requirements
Bidders must demonstrate experience in similar projects involving dam removal, habitat restoration, and environmental permitting processes. They are encouraged to utilize qualified local businesses including Minority/Women-owned Business Enterprises (MWBE).
