Summary of VI. New Drainage Systems, Improvements, Laterals and Other Modifications of Drainage System Summary of VI. New Drainage Systems, Improvements, Laterals and Other Modifications of Drainage System

Summary

There are four (4) types of proceedings that constitute a drainage project in Minn. Stat. Chapter 103E: Establishments, Improvements, Improvements of an Outlet, and Laterals. These and other types of drainage activities that require the appointment of an engineer are provided with their respective reference sections:

1. Establishment (Minn. Stat. § 103E.212) (Chapter 3, Section VI. 1);
   
2. Improvement (Minn. Stat. § 103E.215) (Chapter 3, Section VI, 2);
   
3. Improvement of Outlet (Minn. Stat. § 103E.221) (Chapter 3, Section VI, 3);
   
4. Laterals (Minn. Stat. § 103E.225) (Chapter 3, Section VI, 4);
   

Other:

• Impounding, Rerouting and Diverting of Drainage System Waters (Minn. Stat. § 103E.227) (Chapter 3, Section VI 5);
  

In response to a drainage project petition, the project engineer is responsible for recommending a practical drainage project design, to inform the drainage authority in the preliminary report on issues related to feasibility, and present a fully defined and constructible drainage project in the detailed survey report. Additional detailed recommendations related to engineering tasks for specific project types include:

• Hydrologic and hydraulic analysis (Chapter 3, Section VI, B.1);
  
• Ditch/Channel Hydraulic Design (Chapter 3, Section VI, B.2);
  
• Bridge/Culvert Hydraulic Analysis and Design (Chapter 3, Section VI, B.3);
  
• Erosion Control for Drainage Water Entry to a Public Ditch (Chapter 3, Section VI, B.4);
  
• Miscellaneous Structures (Chapter 3, Section VI, B.5);
• Channel Geometry (Chapter 3, Section VI, B.6); and
  
• Vegetated Ditch Buffer Strips (Chapter 3, Section VI, B.7).
