A Question and Response document will be shared with all recipients of the RFP by July 21, 2025. Blackbrook Creek Stream Restoration The Blackbrook Creek Stream Restoration Project will restore approximately 715 linear feet (0.14 miles) of Blackbrook Creek to a natural stream configuration with floodplain connectivity and 2 acres of riparian and wetland habitat. The restoration site begins at the mouth of the Creek where it empties into Mentor Marsh and extends upstream to a culvert near the remediated Osborne Salt Fill. Key components of the restoration include: Channel Restoration: The channel will be restored using the Self-Forming Channel design method. The length of the existing channel will be filled, creating a wide, flat floodplain. This will provide space for fluvial processes to develop bars, benches, and an inset channel that is stable and sustainable through natural erosional and depositional processes. Floodplain and Wetland Creation: Approximately 1.2 acres of floodplain and 0.8 acres of adjacent wetland will be reconnected and restored. Sand-Seepage Berms: A series of permeable berms will span the valley, forming pools for wetland habitat and temporarily storing floodwater. These berms will filter sediment, nutrients, and invasive species from runoff before it enters the Marsh. Native Vegetation: The floodplain and streambanks will be planted with native riparian and wetland species to improve wildlife habitat and stabilize soils. Construction Materials: Fill material will be sourced on-site by cutting back the western bank, eliminating the need for material import except for the berms, which could use beneficial use dredge material from a local facility. The restoration will enhance habitat for native birds, fish, amphibians, and macroinvertebrates, and improve water quality by increasing the system's capacity to process sediment and nutrients. The restored stream and wetland system is estimated to prevent 508 lbs. of phosphorus, 2,580 lbs. of nitrogen, and 172,600 lbs. of sediment from entering the Mentor Marsh annually. There are no existing utilities, roadways, or structures in the project area, minimizing the need for complex engineering. The area provides a unique opportunity to study and showcase the self-forming channel process as a model for future restoration projects.
