These new laws expand state agencies’ supervisory responsibilities to ensure that local governments comply with state mandates. Effective administration of these laws will require state agencies to accurately estimate the amount of new housing that might be created and to target review to the jurisdictions that are failing to meet the relevant requirements. Here we present quantitative tools both for prioritizing review of local plans and zoning ordinances and for estimating future housing development. We applied the tools to the implementation of California laws requiring local governments to amend their zoning ordinances to allow accessory dwelling units on parcels zoned for detached single-family housing development. We provide computer code, written in the open-source statistical computing language R, that implements these tools. Although we present off-the-shelf tools, our proposed tools should supplement other regulatory techniques rather than serving as a substitute.Takeaway for practice Requirements for local governments to allow infill development should be accompanied by mandates for data collection. With good data, state agencies can use open-source statistical software to create quantitative measures that can help estimate future housing production and set priorities for reviewing local plans and zoning ordinances.Keywords: housinginfill developmentland use planningregulationzoning Supplemental MaterialSupplemental data for this article can be found on the publisher’s website. Replication code is available at https://doi.org/10.7910/DVN/LNJ5X3Notes1 This follows from two provisions of state law. First, regional housing need is subdivided into different levels of affordability, with “housing for lower income households” defined as housing that is affordable to households earning up to 80% of the area median income (California Government Code, sec. 65584(f), Citation2023; California Health and Safety Code, sec. 50079.5, Citation2023). Such households typically comprise about 40% of the total (see, e.g., California HCD, Citation2020a, Attachment 1; Citation2020b, Attachment 1). Second, the sites through which cities accommodate their “lower income” housing target must be zoned at densities that allow for multifamily housing (California Government Code, sec. 65583.2, Citation2023).2 In 2023, Montana also adopted laws enhancing planning requirements and requiring certain jurisdictions to allow duplexes in areas zoned for single-family development, but these laws do not require state administrative review of local ordinances (State of Montana, Citation2023a, Citation2023b).3 If an Oregon city fails to adopt a compliant, state-certified missing-middle zoning ordinance, it eventually becomes subject to a default state-promulgated missing-middle code (Oregon House Bill 2001, Citation201","PeriodicalId":48248,"journal":{"name":"Journal of the American Planning Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135092671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this Viewpoint, I present a systemwide approach to financing and fulfilling the transportation needs of those who do not drive while at the same time providing a congestion-free travel choice for those who do. It combines congestion pricing with cash rewards for those who choose to share rides on a network of congestion-free lanes converted from general-use lanes to priced lanes. Net revenues support multimodal travel options including transit, carpooling, and mobility hubs with transportation services to and from trip origins and final destinations, also known as first- and last-mile services. The strategy would allow existing metropolitan freeway networks to be transformed into financially viable, sustainable, and equitable multimodal systems providing high-quality travel choices that could lead to more sustainable urban development patterns.Keywords: cash rewardscongestion pricinghigh-occupancy toll lanessustainable developmenttransportation financing Notes1 The economic rationale for roadway congestion pricing is that drivers impose significant external costs that they do not pay for, such as travel delays imposed on other travelers, as well as environmental costs imposed on society at large. This distorts their choice of travel mode in favor of driving, increasing traffic demand and reducing use of alternatives such as shared travel modes.2 Cash payments would be funded using revenue from tolls paid by those who run out of toll credits.3 Alternatively, the program could give discounted toll rates to low-income drivers.4 New tolls have successfully been imposed on all lanes of existing free bridges, such as the SR 520 bridge in Seattle (USDOT, Citation2015).5 For example, see Atlanta’s existing and planned express lanes network (Georgia Department of Transportation, Citation2021).6 Converting two lanes was found to provide less net operating revenue due to the increase in rewards that would need to be paid out because a larger share of solo drivers would have to be attracted to transit or carpooling to ensure that congestion gets no worse on the free lanes; both the reward per person and the number of persons to be rewarded would increase significantly.7 With less congestion, toll rates would be lower, reducing revenue. However, with lower traffic demand, a smaller share of commuters would need to be attracted to shared travel modes to achieve targeted traffic volumes, reducing the number of commuters to be rewarded as well as the magnitude of the required cash reward per commuter.Additional informationNotes on contributorsPatrick DeCorla-SouzaPATRICK DECORLA-SOUZA (pdecorla","PeriodicalId":48248,"journal":{"name":"Journal of the American Planning Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135590466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this interest, there has been little cross-country comparative research regarding the adoption of technology within the planning profession and even less that addresses planners’ expectations and desires for future digital tools. We undertook a multinational online survey of planners in the United States, Canada, the United Kingdom, Australia, and New Zealand to gain a comprehensive understanding of current and expected future use of data and software in planning practice. Although the current use of data-intensive digital tools was limited, we found widespread expectations of change across the planning profession. Remarkable similarities were observed across the countries surveyed. The biggest differences in tech use were among planners undertaking strategic, specialist, and regulatory roles.Takeaway for practice Planning organizations around the world should prepare for a new wave of digital change as many technical obstacles that previously hindered the rapid exchange and analysis of vast amounts of data have now been overcome. Continued development of digital skills among planners is important but should be paired with career pathways for digital specialists within the profession. Planners should not complacently assume that adopting digital technologies will automatically lead to more effective and equitable planning outcomes.

Affordable housing in TODs, however, remains scarce despite state-level policies, interest group advocacy, and developer enthusiasm. We used a multiple case study method and focused on TOD areas in communities with disadvantaged populations in Southern California to examine barriers to and opportunities for affordable housing. We examined the contents of specific plans adopted by local governments to facilitate TODs around 10 selected transit stations in Los Angeles and Orange counties and conducted interviews with planners, policymakers, and developers involved in achieving affordable housing. Our findings indicated that although TOD specific plans permitted higher-density developments, they neither prioritized affordable housing nor presented a coherent vision for an inclusive transit community that would address the needs of different types of households. Moreover, onerous requirements for securing subsidies, patchwork financing, uncertainties in the approval process, and competition from market-rate housing inhibited affordable housing development. Although we did not analyze community opposition to TODs, it was hinted at by our interviewees.Takeaway for practice Targeting affordable housing in TODs, providing incentives, and strengthening the institutional framework are critical to achieving inclusive transit communities. The development of TODs in a politically fragmented region like Southern California necessitates a lead organization to procure affordable housing investments and strengthen the housing–transportation nexus.

As a result, many American cities have begun to reduce or remove parking minimums in some or all areas. However, existing research on the effects of these policy changes has focused only on the analysis of parking supply. We investigated the broader results of parking reform at a small university city in the Midwest that removed MPRs for downtown and university districts. Our quasi-experimental research found that onsite parking construction in the deregulated zones decreased dramatically, from 108% of the earlier requirement to only 46%, clearly indicating that MPRs had enforced oversupply of parking. Of the 43 new major developments built in the 7 years following the parking reform, 84% provided less parking than previous requirements, including eight developments with zero parking. The reduction in onsite parking led to more efficient use of existing parking stock, both public and private. Furthermore, the removal of MPRs, combined with other policies, helped improve urban form by increasing housing density, promoting active building frontages, and guiding a growing share of new developments to transit-rich and walkable districts.Takeaway for practice American cities stand to benefit greatly by relaxing or repealing parking requirements. Cities that expect resistance to parking reforms can take a targeted and incremental approach, first removing MPRs in denser areas such as downtowns, transit corridors, and other prime districts where an oversupply of parking is typically being reinforced by uniform MPRs. The case of Champaign (IL) demonstrates that a targeted district-scale reform is likely to encounter minimal opposition.Keywords: minimum parking requirementsparkingparking reformquasi-experimental researchurban development ACKNOWLEDGMENTSWe are thankful to Colton Johnson and Jonah Farran, undergraduate students in the Department of Urban and Regional Planning at the University of Illinois, for their support in data collection and surveys.
