Patty Noll shared the history and details of Kansas City's award-winning Stream Buffer Ordinance. The stream buffer defines three zones along a stream: the streamside zone (25 feet from the stream bank), the riparian zone (from streamside zone to the limit of the 100-year flood), and the outer zone (75 feet from the riparian zone limit). She explained the development within the outer zone allows denser development with fewer required parking spaces, so that developers can use the developable area more effectively since they can't build in the streamside nor riparian zones.
