spindletop bayou mitigation bank
chamber & liberty counties, texas
WLS is currently working with Ecosystem Renewal, LLC on a wetland and stream ecosystem mitigation bank in Liberty County, Texas. WLS partnered with EcoGenesis to provide technical design services for the development of the Spindletop Bayou Mitigation Bank (SBMB). The proposed 460-acre bank will provide over 400 acres of restored wetlands and 10,000 linear feet of headwater stream in the Western Gulf Coastal Plain Ecoregion of the USACE Galveston District. The full restoration of this self-sustaining ecosystem will provide significant habitat and water quality improvements to Spindletop Bayou watershed. WLS has facilitated coordination efforts with the Galveston IRT, assisted in the overall credit generation, and provided a stream design for the proposed mitigation site. After completion, this project will be one of the largest and most complex mitigation banks in southeast Texas that involves the restoration of a headwater stream and wetland system.
cedar bayou mitigation bank
liberty county, texas
WLS is currently working with Ecosystem Renewal, LLC on a large wetland and stream mitigation bank located northeast of Houston, Texas. WLS partnered with EcoGenesis to provide site assessments and lead design services for the development of the Cedar Bayou Mitigation Bank (CBMB). The project streams are located in headwaters of the Cedar Bayou watershed, which is a major tributary that flows to Galveston Bay. An extensive ditch network was constructed and maintained over the last century that has altered the natural drainage patterns throughout the upper watershed. The dredging and maintenance activities have led to a loss of aquatic resource function and degraded conditions.
The project will restore and enhance over 22,000 linear feet of impaired stream channel and over 1,000 acres of diverse wetland habitats in the Western Gulf Coastal Plain Ecoregion. The restoration design will provide diverse habitats and wetland types integrated to the headwater stream system. Due to a century of agricultural practices on hard pan clay soils, this region experiences high flood frequency during large precipitation events. WLS will utilize a combination of Priority I and Priority II approaches to maximize ecological uplift while creating additional flood storage capacity in what is predicted to be a growth area for the Houston region. The restoration design has been completed and construction is anticipated in Fall 2018.
