EQR is skilled in constructing bioretention
facilities as a water quality control structure.
Given our location in Maryland, we are well
acquainted with the leading work done in this
field by Prince George’s County, Maryland, and
the University of Maryland.
understands how bioretention facilities
function to reduce runoff velocity and capture
pollutants from stormwater before those pollutants
can reach waterways. We have staff with the
expertise to install pipework, filtration stone,
and engineered soil mixes at critical elevations.
What distinguishes our crews is that they understand
how to place materials to minimize compaction
through and around the facility. This increases
infiltration rates so the facilities function
as designed soon after completion. In addition,
our nursery management staff knows which plant
species perform well in these facilities. Our
construction crews are also adept at identifying
impervious subsoils and installing underdrains
to maintain proper infiltration.
EQR is also aware of the conditions under which
a bioretention system may be inappropriate,
such as areas that receive high sediment flows
or excessively sloped terrain.
