woodlands healthy, and the historic trees were dying. To remedy this stormwater
problem and restore moisture to the woodlands, Cahill Associates and Andro-
pogon Associates designed a series of infiltration trenches, beds, and systems
designed to return the water to the soil and prevent erosion (Figure B-34). An
infiltration trench adjacent to the sidewalk on the top of the hill was constructed
to retain stormwater volume. The eroded “ravines” were restored with check
dams. This eco-engineering approach is now endorsed by the cathedral, which
holds tours for watershed groups and officials.
The cathedral continued this philosophy of “stormwater for the natural system”
when the Amphitheater Restoration Project was undertaken in the summer and
fall of 2006. Working together with Michael Vergason Landscape Architects,
Cahill Associates designed a site with minimal grading and a design to return
water to the soils and vegetation. Shallow infiltration trenches at the base of
each new seat wall infiltrate stormwater into the soils above the historic Olmsted
Woods. The amphitheater's stormwater management system effectively recharges
the groundwater, helps maintain healthy woodlands, and reduces erosion and
degradation in a rare spiritual and natural sanctuary in the busy DC area.
