Even if you don't have any other hardship, if you can show that your proposal will reduce some existing nonconformity, such as ground coverage percentage, setbacks, or make a use more conforming, you may be entitle to a variance. A frequent way to do this is by reducing the amount of impervious coverage (i.e. asphalt, concrete, cement) on a lot by substituting pervious materials (i.e. gravel, crushed stone or pervious pavers).
If you have questions, Land Use Staff can assist you in filing an application for a Variance.
