At alarming rates, America’s growing population, industrialization, and consumerism are depleting its finite land and natural resources, while simultaneously accelerating global warming. [This acceleration is largely due to heightened greenhouse gas emissions, which inefficient and unplanned “sprawl” development has increased. Sprawl is a modern “form of urbanization distinguished by leapfrog patterns of development, widespread commercial strips, low density, separated land uses, automobile dominance, and a minimum of public open space.”
In many states, the land use systems in place not accounted for the nation’s rapid population growth. This results in a pattern of inefficient, sprawling suburban and exurban development. Current uncontrolled growth patterns have resulted in challenges to utilities provision, increased infrastructure costs, degraded environmentally sensitive lands, and caused exponential energy consumption. Additionally, motor vehicle dependency due to longer distances travelled between destinations increases greenhouse gas emissions and traffic pollution that complicates health, as well as other social costs, such as unproductive time spent commuting. Sprawling development has created a national infrastructure gap, with current deficiencies in infrastructure approaching $1.5 trillion.
The growth of unchecked sprawl and its grave consequences call for the adoption of sustainable, planned development in order to mitigate the irreparable threats to the environment, natural resources, and quality of life. One impediment is that local governments are ill-equipped to combat this costly devastation without coordinated partnerships between federal, state, and local agencies to “build on their economic strengths” and “grow in environmentally sustainable ways.” Therefore, states should use the power of the purse to incentivize reforming local land use planning to use modern objectives, policies, and regionally coordinated approaches to effectively implement sustainable development strategies, such as “smart growth” management.
America’s Land Use Laws Breed Sprawl
The pursuit of private property as part of the “American Dream” largely promoted sprawl, but it is permitted, if not encouraged by inefficient local land use laws, such as outdated zoning practices that unnecessarily separate residential and commercial uses and prohibit mixed-use development. In Village of Euclid v. Amber Realty Company, the United States Supreme Court upheld the constitutionality of segregated land uses and granted primary authority to local governments over land use matters so long as the decisions were not arbitrary. As a result, the commonly used and court sanctioned non-arbitrary way to design a zoning code was to segregate uses thought to be incompatible with one another. The consequent fragmented and uncoordinated planning often results in patterns of scattered development on large lots exacerbating sprawl. Despite this, it is continuously advanced by local governments without state or federal oversight through the use of their long-held authority over local development planning and reluctance to participate in coordinated regional planning.
Some residents oppose state intervention to curb sprawl because they might believe that sprawl is a consequence of free market choices. Some oppose state intervention because they believe that spending for growth management initiatives, such as policies promoting transit oriented development, increase the economic burden for those who do not use public transit; additionally, more road construction is preferable for continued car use[. On the other hand, some believe that sprawl is the result of the government’s failure to have the foresight needed plan for efficient communities and that its dangers must be combatted with smart growth management.
Smart Growth’s Call for Intergovernmental Coordination to Combat Sprawl
“Smart Growth” is a term for planned land use practices, policies, and controls that improve efficiency, economic prosperity, and sustainability by creating development patterns that reduce the need to move throughout the city. Smart growth restricts low density development and contains urban growth within designated areas, thus curbing sprawl. Smart growth uses land planning strategies, such as increasing density, by directing development towards existing communities to achieve its goals, which include reducing greenhouse gas emissions, balancing business and development interests with environmental concerns, preserving open spaces, and providing a variety of housing and job opportunities with compact mixed-use development.
To create sustainable land use patterns using smart growth management calls for coordinated efforts between all levels of government and using consensus-building processes. Implementing smart growth development will require reforming current land use policies and practices, such as replacing outdated zoning with mixed-use land development, which is a key component. Reform will require states to confront obstacles presented by the precedent of local governments’ [control in the land use process, and instead allow states to require or incentivize regionally coordinated planning. States can significantly influence intergovernmental collaboration and guide sustainable development through the use of strategic funding incentives, regulatory controls, statutory reforms, and other incentive based intergovernmental cooperation.
California, for example, created a smart growth initiative, the Sustainable Communities Act of 2008 (SB 375), which links land use planning, including regional transportation infrastructure development and regional affordable housing needs, with regional GHG emission reduction targets. SB 375 was enacted after the legislature realized that the Global Warming Solutions Act of 2006 (AB 32)’s goals of reducing statewide greenhouse gas emissions to 1990 levels by 2020 could not be achieved without improved land use and transportation policies. California’s GHG targets could only be met by reducing Vehicle Miles Traveled (VMT), so SB 375 uses regional transportation plans that discourages automobile dependency by incentivizing compact, mixed-used development located along public transit corridors.
SB 375 works to coordinate “disjointed planning activities and provide incentives for local governments and developers to follow new conscientiously-planned growth patterns.” It also afforded the state increased influence over local land use planning and authority to employ numerous regulatory measures, such as regional transportation planning, increased transit investment, and enhanced multi-modal public transportation to reduce the amount of VMTs. Federal law requires regional metropolitan planning organizations (MPOs) to adopt regional transportation plans, but local compliance with SB 375’s regional plans is voluntary, which necessitates incentives for cities to incorporate the region’s development plans. State agencies provide local governments with guidance to implement smart growth principles to develop sustainable communities, as well as infrastructure funding incentives to embrace conscientiously-planned, regional growth patterns. Transportation-oriented development projects are incentivized to be consistent with the regional Sustainable Communities Strategy (SCS) with state funds for coordination, or with relaxed environmental review requirements under the California Environmental Quality Act (CEQA) for developers.
If cities continue to enact sprawl inducing development patterns, the environment and public infrastructure systems will be exponentially burdened, finite environmental and agricultural lands will be consumed, and the devastating impacts will be extremely difficult to reverse. California is taking substantial steps to curb the emissions of GHGs that contribute to global warming. AB 32 and SB 375 are pieces of ambitious legislation that need to be aggressively pursued in order for their targets to be reached. States must act now and should follow California’s lead to push standards that reduce GHG emissions and likewise advance a bottom-up policy change through funding incentives awarded to local programs that integrate regional development plans to curb sprawl’s devastating, costly impacts.
