Yet integrative approaches to consider multiple ES also require
integration at the administrative level, because competences for
streetscapes are often divided. In Paris, for example, streetscape
responsibilities involve the departments of the public road
network, urban waste management and city planning (Pellegrini,
2012). Alley greening programs in the U.S. show that a range of
collaborating agencies and organizations beyond public administration
can be involved in funding and implementing ES-oriented
concepts in streetscapes (Newell et al., 2013). In Germany, many
planners are aware of the ES concept, but lack support from higher
levels as well as the appropriate resources to be able to implement
related concepts (Albert et al., 2014).
