Yard Flooding

Cause: Drainage has been blocked
Solution: Remove blockage.

Drainage problems can develop over time from debris, sedimentation or obstructions like sand boxes, firewood and shrubbery. Removal of these obstructions can restore proper drainage.

If a blockage occurs in a public right-of-way such as an inlet or catch basin, the Village's Public Works Department should be contacted for maintenance work. Residents can assist in this effort by removing leaves, grass and trash from these structures. If a blockage is on private property, that property owner should be approached to determine whether the blockage can be voluntarily removed.  If there is a dispute over removing a blockage on private property, state drainage law may provide recourse for its removal. The Village's Community Development Department can offer guidance in this circumstance.

Note that debris removal from a culvert during heavy runoff can be hazardous. Therefore, preventative maintenance is best to ensure adequate drainage.

Cause: Yard is flat with minor ponding (< 3 days)
Solution: Install a drain tile, swale or dry well.

Drain tiles and swales provide a pathway for water to flow through to higher land.  Drain tiles should slope at least two percent (two feet fall for every 100 feet of length). Drain tiles may be perforated (water seeps into tile) or non-perforated (water enters through inlets). Drain tiles discharge either to a front yard or into a storm sewer inlet, as allowed by the Village.  Connection to a combined sewer (sanitary and storm) is not permitted.

Swales should slope at least one percent (one foot of fall for every 100 feet of length).  Gutter downspouts should extend to swales via non-perforated tiles. The ground surface around the house should slope away from the foundation toward the swales.

Dry wells are underground retention areas. They absorb frequent rainfalls that pose problems for grass growth. Dry wells will occasionally overflow after successive rainfalls or especially heavy rainfalls. Dry wells are generally installed when drain tiles and swales are unfeasible.

This work requires a building permit from the Village. The Village reviews such projects to ensure that there will be no adverse impact on other property owners.

The Village has created a Backyard Drainage Program to reimburse two or more qualifying property owners for half of the cost of reducing yard ponding. Contact the Community Development Department at (630) 620-5749 for more information.

Cause: Yard is in a floodplain
Solution: Regrade yard but maintain floodplain storage.

It may be possible to regrade a yard that is in a floodplain. By lowering some areas through excavation, other areas may be raised by filling. However, the post-construction floodplain should store and pass water in about the same manner as the pre-construction floodplain.  This work requires the assistance of a registered professional engineer. Permits are required from the Village and DuPage County.
