“…California is a prime location to study residential parking supply and its implications for ADU development. The state is mired in a major housing supply and affordability crisis that has been exacerbated by decades of planning and building for automobility, including capacious street width standards and off-street parking requirements (Guo et al, 2012;Volker et al, 2019). The state government has recently embraced ADUs as an integral part of solving the housing crisis and changed state law to make it easier than ever before to permit ADUs (California Govern-ment Code Section 65852.2, n.d.; Volker, 2020).…”

Not enough parking, you say? A study of garage use and parking supply for single-family homes in Sacramento and implications for ADUs

Accessory dwelling units (ADUs) are increasingly touted as part of the solution to the intransigent housing shortages facing many metropolitan areas across the United States. But numerous barriers to ADU development persist, including opposition by neighboring households. One persistent question is whether ADU residents would overwhelm on-street parking in the predominately single-family neighborhoods where ADUs are typically built. That question is difficult to answer because there is a surprising dearth of research on the effective parking supply in single-family neighborhoods. We use a survey of homeowners in Sacramento, California, to investigate the supply and sufficiency of residential parking for single-family homes, including how households actually use their garages, and help answer the ADU parking conundrum. After estimating and accounting for actual garage use, we find that more than 75% of households have enough off-street parking available to park all their vehicles. When we combine off-street and on-street parking supplies, we find that households have an average of 1.6 more parking spaces available to them than they have vehicles. That parking surplus is more than enough to accommodate the average ADU tenant and their vehicle, belying claims that ADUs will overwhelm existing parking supplies in single-family neighborhoods.

“…For example, a study of street widening in Los Angeles, a common form traffic mitigation, found that requirements of street widening are often based on overpredicted traffic flows attributed to proposed developments, which may negatively affect housing affordability because it introduces burdensome development costs, and more importantly, land dedicated to street widening means less land for housing (Manville 2017). As a result, the LOS-based TIA tends to disproportionately affect urban developments because it increases the cost of development in dense urban areas where there tends to be more traffic and the cost of mitigation measures is higher (Volker, Lee, and Fitch 2019). Thus, many researchers have been studying ways to improve trip generation analyses by estimating trip generation rates from characteristics of urban form at the neighborhood level and sociodemographics at the household level, based on theories of travel demand and travel behavior (Clifton et al 2012; Clifton, Currans, and Muhs 2013, 2015; Currans 2017; Currans et al 2020; Currans and Clifton 2015; Ewing et al 2017; Howell et al 2018; Tian et al 2020; Tian, Park, and Ewing 2019).…”

Traffic impact analysis (TIA), which estimates the nearby traffic effects of proposed land development, tends to bias against higher density developments in urban areas where traffic is often heavy and travel alternatives plentiful. This has important implications for housing supply and affordability, suburban sprawl, and private vehicle dependence. We examine the understudied implications of TIA on housing by drawing on empirical evidence from distinct bodies of research in the transportation and land use planning literatures to describe the mechanisms through which TIA may affect housing markets. We conclude that TIAs likely have negative effects on both urban housing production and affordability.

“…Other articles use a wider variety of approaches to either explore the future or assess methods for doing so. Volker et al (2019) use a counterfactual approach to examine how California's plan to replace level of service calculations with vehicle miles traveled in development approval processes might help housing production, finding some positive outcomes. Lewis and Marantz (2019) assess how surveys of planners about land use regulations, conducted over previous decades, predicted long-term housing production.…”

COVID-19 is at the front and center of planning discussion. An emergent phenomenon, it is too soon to make definitive conclusions about its longterm effects on the field, cities, and regions. However, in this editorial I reflect on how COVID-19 intersects with the Journal of the American Planning Association's (JAPA's) editorial work, content, and links to the profession. JAPA's editorial workplace already spans a wide geography, and a steady stream of recent articles have examined how planning can engage alternative futures. JAPA already hosts important forward-looking conversations that challenge planning practice. These can play a useful part as the profession addresses the effects of COVID-19 itself, social or physical distancing, and the associated economic downturn.
