Concrete Contractor in Inver Grove Heights, MN

Inver Grove Heights sits at the eastern edge of our service radius in Dakota County, and it has a detailed driveway ordinance. City Code section 10-15-20 covers driveways specifically, and it does not leave much to interpretation. The requirement itself is unambiguous: no driveway may be replaced, constructed or expanded without first obtaining a driveway permit from the city.

Note the word replaced. This is not a permit that only applies to new construction or to expansions. A straight tear out and replacement in the same footprint is covered. The code also puts a clock on it: the work must be completed within one year of permit issuance. That matters for anyone pulling a permit in the fall for a spring pour, because our season runs March to mid October and the one year window needs to still be open when the trucks arrive.

There are three things we could not confirm and will not fill in. We do not know which department issues the driveway permit. We do not know whether a separate right of way or curb cut permit is required in addition to it, and not knowing is not the same as knowing that none is. And the fee is unconfirmed too, because we do not have the city's fee schedule in hand. So on an Inver Grove Heights job we treat the permit path as something to establish by phone with the city before we schedule, and we tell you that rather than pretending the answer is already in hand.

The county fact is the same as the rest of the Dakota County towns we serve. Zone II under Minnesota Rules 1303.1600 sets a minimum footing depth of three and a half feet, forty two inches, for frost protection, and no Inver Grove Heights specific footing depth statement separate from the state rule was found. Frost walls, stoop footings, step landings and foundations all get carried to that depth.

We pour stamped patios, driveways, poured walls and footings here, and we run our own line pump for the lots where a ready mix truck has no useful position. Driveways are typically sold December through March for the following season, which in this city is also a sensible time to be sorting out the permit question rather than doing it in May.

Inver Grove Heights code, in the detail that matters

Width is defined at both ends. The maximum curb opening is thirty two feet for a single driveway and fifty feet combined. There are also minimum widths: a minimum unobstructed width of nine feet where the driveway is not more than one hundred fifty feet long and serves up to two residential units, twelve feet for longer driveways, and twenty feet where more units are served. Those minimums matter on the deeper parcels, where a long private drive back to a house can easily exceed a hundred fifty feet and quietly land in the twelve foot category.

Setback is five feet from side and rear property lines for all driveways, except for approved shared driveway accesses. A rear line setback stated for a driveway is worth noting, because it comes into play on the deeper lots and on properties with detached garages or outbuildings set well back.

Spacing from street intersections runs from twenty to fifty feet depending on street classification. That range is the reason we ask what kind of street you are on before we sketch anything for a corner property. A driveway that works on a local residential street may not clear the requirement on a collector.

The grade rules are the part of this code we find genuinely useful, because they put numbers on something that is usually left to judgment. The access grade may not exceed a boulevard slope of one quarter inch per foot from the top of curb elevation to the property line. From the property line to the building, slope must be between one half of one percent and twenty seven percent. That lower bound is the one homeowners never expect. A driveway that is dead flat is not compliant and, more to the point, is a driveway that holds water and ice all winter. There has to be fall on it.

Materials are specified as bituminous, concrete or paving blocks for the entire width and length, including the portion of the driveway located within the road right of way. That phrase, entire width and length including the right of way portion, is worth reading twice. It rules out a paved driveway that turns to gravel at the boulevard. Crushed rock is allowed on properties zoned A or E under specific conditions, such as access from unimproved streets, which is a real consideration on a property with that zoning.

On housing era we have very little that is solid. A commonly cited median year built for houses and condos in the city is 1990, but that comes from an aggregator rather than a city or census publication, so we treat it as a rough indicator only and would not build a claim on it. On soil and drainage we have nothing at all. No city, county or other credible source stating soil type or drainage characteristics specific to Inver Grove Heights building sites was found. We are not going to invent a subgrade description for a city where nobody published one. We look at what comes out of the hole and price the base off that.

What the code detail does tell us is that this is a city that thinks about driveways as drainage structures, not just as parking surfaces. The boulevard slope limit, the minimum fall from property line to building and the requirement that the right of way portion be paved all point the same direction. On our side that lines up with how we build anyway: the slope conversation happens before the stamp pattern conversation.
