BWSR works in partnership with local Soil and Water Conservation Districts, Watershed Districts, Watershed Management Organizations, Cities, Counties, other state and federal agencies, conservation organizations, and numerous other boards and organizations to provide engineering support services for a number of conservation related programs and functions.

Our goal is to provide engineering support and training for BWSR programs and functions to enable effective engineering solutions to identified natural resource needs and concerns on both private and public lands, including wetland restoration and protection, wildlife habitat protection and improvement, erosion control, water quality restoration and protection, multipurpose drainage management, flood control, and disaster recovery.

Wetland Restoration

The BWSR Technical Services Section provides engineering support for numerous agency administered wetland conservation and regulatory programs and associated agency partnerships. Restoration experiences ranges from small pothole wetlands to large lakebeds and bogs. Important engineering and ecological issues are addressed through the use of advanced restoration methods and strategies. This includes comprehensive site assessment, including topographic surveys, drainage system investigations, and wetland restoration concept planning; design of wetland restoration infrastructure, including drainage system modifications, and hydrology management and associated outlet structure design; and project construction management.

In support of agency wetland restoration programs, BWSR has developed various technical materials including comprehensive guidance documents, design tools, and standard drawings. Many of these technical materials are included and made available here for resource professionals and others to use in support of statewide wetland restoration efforts.

Minnesota Wetland Restoration Guide

This is a comprehensive multi¬disciplinary document that offers sound engineering and ecological principals for restoring functional and sustainable wetlands in Min¬nesota. The information contained in this Guide is intended to assist professionals and nonprofessionals alike in considering, planning, developing, and implementing high quality wetland projects of all types and sizes.

Standard Engineering Design Drawings:

The following table contains a list of standard engineering design drawings that have been created to aide in developing design and construction plans for a variety of wetland restoration sites. Standard drawings are not applicable to every project site and users need to determine the applicability of using these or other more specific design and construction details/drawings. For example, design sheets have been created for simple culverts and trickle drain outlet structures but not for more complex outlets.

All files are available to view or download by clicking on the icon choices in the table below. The DWG format requires an AutoCAD viewer. PDF files require Acrobat Reader . Regardless of the format selected, the drawings are developed to be layer controlled, allowing users to easily modify and format each desired sheet to accommodate specific design and construction needs.

Non-Point Engineering Assistance Program

Program Purpose

To provide conservation engineering assistance to private landowners through soil and water conservation districts (SWCDs) statewide for a variety of non-point conservation practices on private lands, including feedlot runoff control, erosion control, wetland restoration and other water quantity and water quality management practices.

Program History

This program was established in 1994 in conjunction with the Agricultural Best Management Practices and Clean Water Partnership Loan Programs, which began receiving funding from the State Revolving Fund. Accelerated technical assistance was identified as a critical need for program implementation. SWCDs, BWSR and the USDA Natural Resources Conservation Service (NRCS) identified engineering assistance as the highest priority technical assistance need. Eleven joint powers groups of soil and water conservation districts were created statewide in early 1995 to employ professional engineer and technician teams to provide technical assistance to and through member soil and water conservation districts. The associated joint powers boards are composed of a supervisor from each of the member soil and water conservation districts. One of the member SWCDs serves as the fiscal agent for the joint powers board and the program. One or more member SWCDs serve as a host district and manager for the engineer(s) and technician(s) employed by the joint powers boards. In 2009, the original eleven joint powers areas were consolidated to eight SWCD Technical Service Areas (TSAs) and co-aligned with statewide administrative areas of the Minnesota Association of Soil and Water Conservation Districts. From the beginning, NPEAP staff has utilized current surveying and design technology to help provide effective and efficient engineering assistance. Through other programs and funding sources, some SWCD TSAs have expanded the number of staff and types of expertise they employ to provide shared technical assistance to member SWCDs.

Coordination and Funding:

Non-Point Engineering Assistance staff provide technical assistance to and through member SWCDs, in cooperation with the USDA NRCS, BWSR and other local, state, and federal agencies. BWSR provides annual base grant funding, as well as policy, administrative, and technical consultation to the joint powers boards and their staff. Base grant funding has been level for a number of years, which has required an increasing local share from other sources of funding. SWCD TSAs can receive additional technical assistance funding through fees for service, member SWCD contributions and specific project grants, including the Erosion Control and Water Management Program, applicable BWSR Clean Water Fund Competitive Grant Programs, the EPA Section 319 Grant Program, and other grant funding sources.


Each SWCD TSA provides an annual Accomplishments Report to BWSR that is then collated with the reports from other TSAs. Up until 2015 these reports were intended to capture only TSA accomplishments related to the Non Point Engineering Assistance Program. The CY 2016 report was a transition year where the Accomplishments Report captures all SWCD TSA accomplishments no matter what the funding source. BWSR creates documents that summarize those outcomes. Those summaries are found below. (Please note that the reporting form changed in 2017.)
