Policy overview of “Strategies for discouraging surface parking lots downtown” by Todd Litman of the Victoria Transport Policy Institute, noting that some cities implement parking maximums (also called “lids”) which limit the total number of parking spaces in an area, or place a limit on temporary commercial parking lots.
Parking Maximums – http://www.vtpi.org/park_man_comp.pdf – refers to a situation in which an upper limit is placed on parking supply, either at individual sites or in an area. Area-wide limits are called Parking Caps. These can be in addition to or instead of minimum parking requirements (Manville and Shoup, 2005).
Excessive parking supply can also be discouraged by reducing public parking supplies, imposing a special parking tax, and by enforcing regulations that limit temporary parking facilities.
Maximums often apply only to certain types of parking, such as long-term, single-use, free, or surface parking, depending on planning objectives. These strategies are usually implemented in large commercial centers as part of integrated programs to reduce excessive parking supply, encourage use of alternative modes, create more compact development patterns, create more attractive streetscapes, and preserve historic buildings.
It could be argued that maximums are as unnecessary as minimum parking requirements. Parking regulations could simply be eliminated, allowing property owners to determine how much parking to supply at their sites. However, parking minimums have been applied for decades, resulting in well-established transport and land use market distortions. As a result, left to itself the market may be slow to reach an optimal level, so parking maximums may be necessary to achieve quicker benefits.
Since businesses may consider abundant, free, on-site parking to convey a competitive advantage, individual firms often find it difficult to reduce supply. Parking maximums that apply equally to all businesses may be an acceptable and effective way to reduce supply in an area. A study comparing various cities found that (Martens, 2006):
• Many European cities restrict commercial building parking supply, ranging from 270 to 500 square meters of office floor area per parking space (approximately 0.2 to 0.37 parking spaces per 1,000 square feet).
• Management of on-street and off-street public parking spaces is a natural complement of restrictive norms with regard to private parking places.
• Restrictive parking policies and public transport improvements support each other, but major transit service improvements need not precede adoption of parking restrictions.
• Restrictive city center parking policies have been introduced without strict regulations preventing unwanted suburbanization of economic activities.
• Case studies suggest that parking restrictions will not have negative economic impacts if implemented in cities with a strong and vibrant economic structure.
The City of Seattle requires that major institutions which propose to provide more than 135% of minimum required parking supply develop a transportation management plan to help reduce trip generation and parking demand (SMC 23.54.016). San Francisco places a two year limit on the use of vacant downtown parcels for parking lots, to encourage redevelopment (Manville and Shoup, 2005).
