2 Severn River Watershed

3 Area = 81 square miles (85% is land) (0.12 % Chesapeake watershed) 110,000 people Rainfall = 40 inches annually (56 billion gallons, about a Billion rain barrels) Forests & trees disappearing fast, no control outside Critical Area, weak Impervious cover increasing fast Water quality & resources in severe decline.

5 Severn River Watershed Trends Deforestation, tree removal, non-native plants Growing population, roads, buildings Growing energy & water use, trash/sewage Declining chemical & bacterial water quality Declining aquatic life (abundance & variety) Degrading shoreline environments Increasing power boat traffic, waves & effluents Balkanized neighborhoods impede walking/biking Most public access to water is gone Public awareness growing (weak commitment).

7 Watershed Needs Bay health depends on tributaries (Severn River) Severn River health depends on watershed land What happens in and near the water is Critical So is what happens far from water’s view Address watershed components holistically –Water & Critical Area practices –Forest, tree & vegetation practices –Development, use of land, impervious cover –Infrastructure: stormwater, sewage & septic –Education, laws, regulations, peer pressure.

8 Kill trees to plant people?

9 Public awareness slow to develop Effective public policies even slower Positive steps: Bay trust fund, restoration & cleanup projects, energetic civic groups like SRA Bay Friendly Neighborhood Program Tensions: watershed goals & property rights Critical Area Law strengthened, but challenges Good stormwater law failed 4/3 (we’ll be back) Weak stormwater tax credit (10% over 5 years) Watershed Progress?

10 Rain Barrels: Perspective, Please Weak tax credit of 10% spread over 5 years 6 applications for rain barrels, 1 granted Annual rainfall = 1 Billion rain barrels Rain barrels, compensate for tree removal But what’s one mature oak tree worth? –Wettable, 1-2 rainbarrels will re-evaporate –Builds soakable soil for prolonged root uptake –Uptake/transpiration 1-2 rainbarrels per day –1 Tree = about 10 well-managed rain barrels Kill one, no penalty. Keep one, no reward. We need better public policy.
