Confluence has recently been retained by the Montana Department of Transportation (MDT) to carry out a three year term contract for performing wetlands monitoring on MDT’s wetland mitigation sites throughout Montana. Confluence’s Brian Sandefur, based in Bozeman, Montana, will be leading a team of 11 professionals to carry out annual wetland monitoring and reporting on MDT’s 23 wetland mitigation sites across the state. All wetland work tasks will be completed to fulfill U.S. Army Corps of Engineers requirements for documenting success of wetland construction at each site. Annual monitoring reports will be submitted to MDT and posted on their website. Sandefur has delineated and monitored thousands of acres of wetlands and has executed numerous successful mitigation plans. He is an effective team leader and works well with local, state, and federal agencies.
Confluence has been retained to quantify sediment loads from upland sources using GIS and Universal Soil Loss Equation (USLE) modeling strategies in the Boulder-Elkhorn TMDL Planning Area. Confluence has significant experience modeling sediment using GIS based USLE sediment models. We have successfully developed and implemented six watershed scale USLE models to characterize stream sediment: Upper Big Hole, Middle/Lower Big Hole, Jefferson River, Tobacco River, Lower Clark Fork, and Shields River. The models are used to characterize sediment loads and to establish potential load reductions in DEQ’s watershed planning process. DEQ will utilize the model to summarize the extent and effectiveness of existing and/or potential riparian buffer conditions as they relate to various sediment sources unique to land uses within the watershed. Various land use best management practices and other appropriate soil and water conservation practices will be developed.
Confluence has made ongoing progress towards designing rehabilitation plans for Goose Creek, located in the Upper West Branch of Priest River in the Idaho Panhandle. The Kalispell Tribe of Nations retained Confluence earlier this year to develop a conceptual design for restoring 4 miles of Goose Creek. Historic land uses along Goose Creek included channelizing several thousand feet of the creek. The conceptual restoration plan will include restoring the creek to its historic elevation in order to provide improved in-stream habitat and a functional floodplain with dense riparian vegetation. The conceptual plan for this large stream restoration project is expected to be completed in the spring of 2010.
Confluence Consulting offers many natural resource planning, design, and consulting services. These include stream, lake, and wetland habitat restoration, floodplain studies, environmental permitting and compliance, GIS mapping, complex database management, ecological assessment and monitoring, and bioengineering. We are capable of providing design-build services for a wide variety of projects, and have worked closely with local, state, and federal agencies, Native American Tribes, watershed groups, private landowners, and many architecture and engineering firms.
