During his tenure, ARCADIS US grew its revenue five times, while improving
bottom line performance ten times. Blake was instrumental in the integration
of a number of large mergers, notably with the environmental firm BBL in 2005
and with water consulting and engineering company Malcolm Pirnie in 2009. Both
additions have contributed significantly to the company’s growth. In addition,
he successfully managed many other acquisitions that enhanced or added service
lines which aided in the ARCADIS expansion. As an Executive Board member he
oversaw the Global Business Line (GBL) Environment; GBL Water; Global Health
and Safety and supported RTKL in their transition to be part of the ARCADIS
family.

Effective June 1, 2013, ARCADIS COO Gary Coates will succeed Blake as CEO for
ARCADIS US while retaining his current position. Zack Smith, chief strategy
officer for ARCADIS US, has been nominated for appointment to assume Blake’s
post on the ARCADIS executive board. Once approved by shareholders, which is
expected, Smith will assume responsibility for Latin America. Smith is
currently member of the board of ARCADIS Logos in Brazil.
