Low Carbon and Resilient Land Use: Part 2
The effects of climate change occur at the local level: storm surges, flooding, wildfires, extreme heat and drought. These all threaten homes, lives and livelihoods, and local governments respond to these threats by adopting policies, plans and regulations to help make safer places for their residents. As described in Choosing to Succeed: Land Use Law & Climate Control, local governments derive their legal authority to control land use from state planning and zoning enabling acts. These laws authorize local regulations that encourage the “most appropriate use of land,” which includes more than just zoning; municipalities also use this authority to adopt floating zones, overlay zoning, special use districts, planned unit developments and a host of other legal tools that help localities shape settlement patterns in a way that most benefits their communities.
Drawing heavily on this land use authority, local leaders have responded and adapted to climate change by adopting low carbon land use strategies that help their residents and businesses reduce energy use and carbon emissions from buildings and vehicles. Choosing to Succeed catalogs a variety of local examples of low carbon land use. A Marin County, California, land use regulation requires new residential development to meet energy efficiency standards that increase with development size. This regulation references California’s 2019 Building Energy Efficiency Standards, which include photovoltaic standards; energy efficiency improvements for attics, walls, water heating, and lighting; and alignment with the ASHRAE 90.1 2017 national standards.
To reduce carbon dioxide emissions associated with transporting energy from generation plants to points of consumption where people live and work, Pittsburgh’s smart city project created a grid of microgrids that interconnect and incorporate existing district energy systems, and zoning for Pittsburgh’s Uptown Public Realm District requires structured parking to include site features such as connection to the “smart/micro-energy grid.” Pittsburgh’s code also requires buildings publicly financed through tax increment financing (TIF) to meet certain sustainable development requirements, which include distributed energy systems, such as micro-grids, that deliver electricity and thermal energy nearer to consumers.
Local governments also can adopt land use regulations that encourage renewable energy systems to further reduce emissions associated with energy consumption. For example, Butte County, California, amended its zoning code to allow alternative energy structures. For both solar and wind energy, the regulation permits four types of systems that differ based on system size. Permitting requirements vary by system type, requiring larger systems to adhere to more requirements, such as decommissioning, warning signage and noise control requirements.
To protect the vegetated environment that sequesters carbon emissions, municipalities can adopt land use regulations that protect green open space. Knox County, Tennessee, amended its zoning code to adopt its Open Space Preservation Zone that protects existing open space, park and recreation lands, wilderness areas, beach and shoreline areas, scenic routes, wild and scenic rivers, historical and archaeological sites, watersheds and water supply areas, and wildlife and their habitats. Development within these areas must adhere to standards outlined in the County’s open space plan.
In addition to promoting energy-efficient development, renewable energy and open space preservation, local governments can help reduce greenhouse gas emissions by adopting land use regulations that create transit-oriented development around train stations to encourage people to reduce their use of personal vehicles in favor of walking. To encourage transit-oriented development, municipalities can amend their zoning around mass transit to allow mixed uses, including a range of residences, retail, offices and personal and civic services, as well as denser development that supports transit. For example, Yonkers, New York, rezoned a former industrial area to facilitate Hudson Park, a multifamily residential development adjacent to the Yonkers Metro-North train station that includes over 750 apartments and over 18,000 square feet of retail and office space. Hudson Park greatly lowered its residents’ consumption of fossil fuels and per capita water use, among other benefits.
Similarly, municipalities without access to mass transit can employ transit-efficient development by strategically amending zoning for certain neighborhoods to increase their development density and allow mixed uses, creating more vibrant spaces for pedestrians and paving the way for future transit opportunities. Choosing to Succeed: Land Use Law & Climate Control describes transit-efficient development and these other low carbon land use strategies in detail, presenting an array of land use tools local governments can employ to help reduce the greenhouse gas emissions that contribute to climate change.
