3 Historic Campus (1874) 2,400 Acre Extended Campus One of the Largest Universities (25) (Big 10) 39,200 Students 15,200 Staff and Faculty

4 Historic Teays River Valley

5 Well Head Locations Federal and State Water Quality Federal NPDES Phase II MS4 Permit

6 Why do a Master Plan? No over-arching strategy for managing stormwater comprehensively as a resource, or for protecting their groundwater. Strategic plan ( ) Master plan (2009) Well-head protection program Some constructed BMPs Minor infractions with MS4 permit

7 Process Understand Historic Rainfall & Environmental Data Review of Existing Conditions Analysis of Runoff & Pollutant Loading, Water Balance Model Opportunity & Constraints Mapping Prioritized Recommendations, Case Studies Guidelines for Stormwater Policy

8 Historic Rainfall & Environmental Data Watershed Context- geology, soils, groundwater Precipitation Patterns Historic Hydrology Remaining Natural Resources
