2-11-1 General Information

Permit applications received by the DNR must contain plans for the proposed activity. In many cases, plans must also show the existing conditions of the area prior to the proposed project. The following example project plans illustrate the key items required for DNR review. Permit applications without the key information may substantially prolong the review process.

2-11-2 Items that should be on every plan

• Streams / other water features
• Roads (including railroads)
• Existing Structures (buildings, parking lots, etc)
• Proposed structures
• Cross Sections if applicable
• Property Limits
• North Arrow
• Scale (numerical / graphical)
• Horizontal / Vertical Benchmarks
• Horizontal / Vertical Datums
• Contours (including date of photography, if applicable)
• Date
• Preparer's Name

Plans should be to scale (Standard scale found on engineering scale).

Use an aerial photograph of the project site for a base if nothing else is available (Photos are available online at Terraserver.com . Another set of aerial maps is maintained by and available at the State land Office).

2-11-3 Minimum Required Information by Project Type
