STORAGE VAULT FOR STORMWATER AT EPA HEADQUATERS

first generation modular technology and the new systems will
just expand the benefits." These include changes to growing
media formulations to improve water retention, changes to
the design of modules so that they hold more and slow water
movement, and geotextiles that have the capacity to expand
and retain significant amounts of water. Research on the EPA
green roof was submitted to the Urban Drainage and Flood
Control District which then accepted green roofs as an approved Best Management Practice (BMP). Now developers can
utilize green roofs to meet stormwater requirements without
the additional technical analysis required of non-standard
BMPs. Modular green roofs and green roofs in general have
incorporated additional strategies for retaining and slowing
down the flow of stormwater, thereby improving performance.
At the EPA headquarters in Denver, the volume of water
retained is estimated to be the equivalent of four parking
spots worth of space. The retention vault currently takes up
12 parking spots worth of space. Utilizing new green roof

technology with its increased
stormwater capture potential,
it may be possible for savvy
building engineers in Denver
to design green roof systems
that virtually eliminate the
need for large concrete
retention vaults, thus freeing
up valuable parking spaces.
In the case of the EPA headquarters, this would represent
an estimated $30,240 in
additional parking income
potential for the building annually, plus the savings of not
having to build the retention
vault and associated plumbing. The same benefit, in

terms of right sizing cisterns,
or stormwater management
ponds, can confer immediate
and annual economic savings
for developers and building
owners who utilize green
roof technology to manage
stormwater. "In time, the use
of green roofs will become
standard practice for buildings across North America",
said Gregory Davis at the end
of our visit. Given the many
public and private benefits
they bring, green roofs are
thankfully, already at that
point in many jurisdictions.
