Please complete the Zoning Permit Application (PDF) for retaining walls under four feet in height. Include a site plan with location of wall in relation to property line, and materials of wall. Include impervious surface calculations as well.
Keep in mind:
A permit is required to install a new retaining wall as well as replacing an existing wall.
If the wall is over four feet in height a building permit is required.
For walls under four feet a zoning permit is required to verify the property lines.
Tips for Locating Corner Irons
Renting a metal detector can give you an indication of an iron location before you start digging
You may not be able to find one or more of your property irons. Sometimes irons are dug up when utility work, street construction or similar activity has taken place near your property corners.
If an adjacent neighbor has recently done construction, they likely had to locate their irons and may be able to show you where they found a shared iron(s).
Utility poles, hedges, a sidewalk edge, or a neighbor's fence are not definite indicators of a property line location.
Before doing any digging, you should call Gopher State at 651-454-0002 to locate any utilities.
