It is not recommended, and may require approval from your homeowners association and/or affected adjacent properties. The rear yard
drainage easement, typically located between properties, is usually the low point which will fill with storm runoff once the capacity
of the storm sewer in that area is reached. By filling in this low area, there is potential for higher water levels to be forced onto
adjacent properties which did not exist before filling in the easement. By altering the drainage patterns from the original design,
owners may open themselves up to liability for damages to adjacent properties.
