Tear up unused parking lots, plant trees
Cities are grappling with how to repurpose vast areas of asphalt—especially underused parking lots—into something more valuable, whether that means trees and urban forests, housing, or mixed-use development. Commenters weigh the environmental benefits of reducing heat islands and stormwater runoff against practical issues like private land ownership, parking demand, and the need for better transit and zoning reform. Many argue that curbing mandatory parking minimums and car-centric planning is key to creating denser, more walkable, and more sustainable urban environments.
Parking lots, trees, and alternative land uses
- Many agree that surplus surface parking is wasteful and unpleasant; proposals include urban forests, native meadows, community gardens, housing, retail, or solar canopies with EV charging.
- Debate over what green: some prefer trees for shade and heat-island mitigation; others emphasize low-maintenance native meadows and biodiversity, warning against tree monocultures.
- Some suggest greening within lots (medians, planters) as an incremental step, especially where lots are still economically useful.
- Others argue housing and mixed-use buildings are a higher priority than parks in cities with shortages and high rents.
Parking minimums, markets, and regulation
- Strong criticism of mandatory parking minimums: seen as arbitrary, copied between cities, inflating housing costs, reducing supply, worsening pollution, and locking in car dependence.
- Counterargument: without minimums, “underparked” buildings can offload parking conflicts onto surrounding neighborhoods; some residents report real-world frustration finding spaces.
- Suggested alternatives: priced street parking, resident permits with guest passes, letting developers decide parking based on demand, or requiring proof of a parking space to own a car (with Japan cited).
- Concern that completely laissez-faire development can yield buildings with far too little parking, leading to conflict and vandalism.
Urbanization, walkability, and transit
- Many want less car-centric design: more walkable, bikeable, “third places,” smaller distributed shops instead of giant malls, and denser “missing middle” housing.
- Others prefer suburban/car-centric lifestyles and object to being “forced” into dense environments; critics reply that today’s zoning often forces everyone into car dependence.
- US vs European/Japanese cities are compared: European examples show cities without parking minimums plus good transit and bike networks; some US attempts at bike lanes and lane reductions are seen as poorly executed.
Highways, sprawl, and reconfiguration
- Strong support in several comments for tearing down or capping urban freeways (Twin Cities I‑94, Syracuse I‑81, Detroit I‑375, Houston, etc.) to repair neighborhoods and free land for people-focused uses.
- Others fear worse traffic, citing Vancouver and Seattle, and propose tunneling or accepting highways as necessary for long-distance commuters and freight.
- A recurring theme: densifying core cities is framed as key to protecting genuinely rural areas from suburban sprawl.
Environmental & carbon considerations
- Trees and meadows are credited with cooling cities, improving stormwater management, supporting pollinators, and enhancing livability.
- Some ask about carbon payback from tearing up asphalt; answers note asphalt can be recycled and trees sequester significant CO₂ over decades, but others argue abandoned lots can simply be left to “rewild” without removal.
- EVs are debated: switching from ICE to EV helps climate but doesn’t solve land use, congestion, tire microplastics, or habitat fragmentation.
Equity, safety, and quality-of-life concerns
- Urban parks/forests are described as both valuable and, in some cities, de facto homeless encampments associated with trash, fires, and crime; critics stress homelessness is a housing/social policy failure, not a reason to avoid green space.
- Some note US urban areas often feel unsafe compared to cities in East Asia; others highlight that car crashes make rural/suburban areas dangerous in different ways.
- Noise is debated: many blame cars; others cite construction, nightlife, and urban density more broadly.
Skepticism, cost, and property rights
- Several point out that most parking lots are privately owned; without changing zoning and economics, owners will prefer future development or continued parking revenue.
- Some argue if activists want green space, they should purchase land or work through incentives (e.g., taxing impervious surface), not rely on eminent domain.
- A few see the tree-planting push as emotional, lacking cost–benefit analysis and ignoring the nontrivial work of species selection, soil, and maintenance.
