In 2022, Radnor Township made updates to its existing stormwater management ordinance. According to a township notice: “Some big things in the new ordinance include green infrastructure, incentives to reduce impervious surface area, a simplified stormwater management approach, and many others. These changes allow for residents to have more choices when it comes to stormwater management.” A grading permit will not be required for a deck, but a building permit will still be required. Radnor Township has assessed a stormwater management fee on all properties since 2013.
