The city of Haverhill, MA debated pay parking plans for over 35 years to address parking issues in its downtown area, which consists of two distinct sections - an eastern retail section and a western section with restaurants and nightlife. A plan approved in 2012 introduced pay parking in lots but kept streets free in the east, while charging for on-street parking in the west. Data showed the plan pushed cars from lots onto free streets, reducing lot utilization. While it freed up spaces, it also led to overcrowded streets and underutilized lots. Lessons included gaining consultant and public support, compromising where possible but holding the line on pricing, and continually tweaking the plan.
