Stop Requiring Parking!

—By Josh Katz—

No one likes parking lots. They’re ugly and expensive. They enable driving alone and cause pollution. Yet a large portion of urban land across the country has been dedicated to the storage of cars. Despite the cost and the many negative side effects, the paving over of our communities was no accident. In fact, in most places, it’s the law.

The zoning regulations adopted by most American cities require the construction of a minimum number of parking spaces for each new development. These numbers differ by city and land use (e.g. residential, commercial, retail, etc.), but by many measures, they are high and are driving automobile dependence at the expense of our wallets, our environment, and the vibrancy of our communities.

Minimum parking requirements make housing more expensive. Depending on the price of land, one parking space can cost between $3,000 (surface lot) and $50,000 (underground garage) to build. This adds 15%-20% to the cost of construction, which developers pass along to tenants in the form of higher rents. Tenants who don’t own cars are forced to pay the higher rent, effectively subsidizing their neighbors’ car use. By one estimate, Americans spend $374 billion on off-street parking subsides a year. This number doesn’t include the high costs to maintain roads and infrastructure that is incurred by greater car use and shouldered by taxpayers.

Parking lots are larger than they need to be, because zoning regulations demand it. For example, for each bowling lane in a bowling ally, Burlington requires 3 spaces. Anyone building a laundromat must include one parking space per washing machine. These spaces often sit empty.

Excessive asphalt poses an environmental threat. It absorbs sunlight, contributing to the urban heat island effect, which increases temperatures in cities 1°-5° F above surrounding rural areas, with temperature differences at night as great as 22°F. The impervious surfaces of parking lots increase storm water run-off which pollutes our streams, lakes, and rivers. And an overabundance of parking enables and encourages people to drive rather than walk, bike or take a bus. Trips taken in a single occupancy vehicle produce more carbon emissions and air pollution.

Minimum parking requirements make cities less dense. If developers are forced to build a large parking lot beside every new building, it’s impossible for communities to grow up rather than out. It also makes them less walkable. People like to walk alongside active building fronts, not across parking lots. Every expanse of asphalt discourages pedestrian activity and limits the amount of useful activities—housing, retail, jobs and outdoor recreation—that might occur in that space. Parking kills density and all the other good things that are enabled by it, like transit.

Minimum parking requirements have stifled attempts to revitalize urban neighborhoods for decades. But finally, as city planners and policy makers communicate the detrimental effects, things are beginning to change. A national movement to eliminate minimum parking requirements is taking root. Buffalo, St. Paul, and Milwaukee among others, dropped parking minimums in recent years. Other cities such as Portland and Sao Paulo have implemented parking maximums to prevent developers from overbuilding parking. Even in Vermont there is big change on the horizon. Just a few months ago, South Burlington eliminated minimum parking requirements throughout the city in a 3-2 vote, marking them one of the first in Vermont to do so. Montpelier, Williston, and Burlington are currently considering scaling back their minimum parking requirements as well.

The City of Burlington is considering a proposal to eliminate minimum parking requirements within downtown and along bus routes. Some City Councilors are pushing further. They have proposed adding maximum parking requirements in those same areas and including Transportation Demand Management (TDM) requirements in the policy change. In that case, developers would be asked to manage the demand for parking by implementing measures that reduce single occupancy vehicle use such as offering car share memberships at a discount for residents, or providing free bus passes.

A coalition of planners, community organizers, affordable housing advocates, and climate activists are questioning the need for these outdated and harmful regulations. They need the support of everyday people to successfully eliminate them from zoning law.
