A proposed six-month moratorium on warehouse developments in Harford County could end up driving businesses to locate elsewhere in the region. County officials say the pause would allow for a review of policies that were first set long before an explosion in warehouse developments. On Feb. 1, Harford County Executive Bob Cassilly announced legislation that would impose a temporary six-month moratorium on approvals or permits for warehouse developments. The legislation was introduced on Feb. 14 and a public hearing on the legislation is scheduled for March 14.
