Establishing “zoned” parking on a street in Arlington County is governed by a local ordinance. The County requires that 60 percent of the residents request the program and there must be a “measurable indication of overspill from outside the zone”. Block residents must request permit parking through a petition that includes signatures from at least 60 percent of the affected addresses (one signature per address). Petitions are available at http://www.parkarlington.com or by calling 703-228-3344. The AHCA currently takes no position on the establishment of zoned parking on any street in Alcova Heights.
