Attached is the presentation given at the April 2008 monthly PUMP meeting.  This was the kick-off of the Trail Building Tips presentation series and was focused on minimizing trail erosion through proper trail water management.  Thank you to the International Institute for Rural Reconstruction, the USDA Forest Service, UCSB, IMBA, and of course the book Trail Solutions: IMBA's Guide to Building Sweet Singletrack.  Check out a PUMP meeting or www.imba.com for more information.
