Chalking messages and postings on walking surfaces with outdoor exposure are legal postings on University property.  All other forms of chalking (i.e. walls, unexposed areas) are forms of graffiti and will be treated as an act of vandalism.  Students caught chalking on surfaces other than outdoor exposed areas may be ticketed.  Spray chalk must easily dissipate in the rain; some products require power washing to remove.  Use of a product that requires power washing will be regarded as vandalism – read the product label carefully.  (This suspends a portion of UWS Chapter 18.12[updated August 2009] for registered student organizations, approved 11-6-00)
