"The recipients of the 12 pending zones have all received letters explaining the moratorium and that their zones will not be installed until further notice," Martin O'Rourke, the Parking Authority's spokesman, said in an email. The moratorium was prompted by mounting residents' complaints to Council members over a 2007 law allowing owners of electric vehicles to apply for special reserved parking spaces, where they could install curbside charging stations. The law was sponsored by then-Councilman James F. Kenney.
