1. When do I need a grading permit?

If you are doing any earth movement greater than 10 c.y. (one truckload of soil) or any quantity of grading that will alter the existing drainage patterns, you will probably need a grading permit.

2. Why do I need a grading permit?

The city regulates filling and excavation work through a permitting process to protect the interest of both the property owner and the community. Grading and filling operations can cause a number of problems related to drainage, erosion and protection of the wetlands, easements and utilities.

The biggest concern is related to drainage and how it may affect neighboring properties.

We suggest talking to your neighbors regarding your grade/fill project before starting it.

3. I want to have a truckload of black dirt delivered to add to my flower beds--do I need a grading permit?

Probably not. If you have any concerns that your landscaping work may be altering existing drainage patterns, please call Maplewood Public Works. We would rather visit you before there is a problem.

4. Someone can give me a few loads of dirt to level off my yard--do I need a grading permit?

Yes. In fact, you will probably need a grading plan, though it may not have to be very detailed. Often the Engineering Division can provide a contour map of your property and discuss the work with you to verify that there will not be any impacts to you or adjacent properties.

You will likely be required to post a refundable cash escrow to ensure establishment of vegetation in the disturbed areas.

5. My neighbor and I want about 500 cubic yards of fill placed on both our properties--do we need a grading permit?

Yes, both of you will probably be required to submit a grading plan prepared by a qualified person. This plan must be reviewed and approved by the Engineering Division. You will be required to submit a written agreement between you and your neighbor.

An erosion control plan and cash escrow for surety will also be required.

6. How long does it take to get a grading permit?

Simple permits can often be issued within a day or two. More complex permits may require a week or more to review.

Note: Sites that disturb over one acre of land also require permits from the watershed district and the MPCA.
