Climate adaptation increasingly considers wetland restoration as a nature-based solution to reduce flood risk and provide co-benefits such as species protection, water resource management, and public recreation access. However, barriers must be identified and overcome to increase the pace and scale of wetland restoration for adaptive benefits. We argue existing climate adaptation barriers frameworks insufficiently address physical and ecological barriers that become apparent during on-the-ground implementation of wetland restoration projects. This paper diagnoses barriers to wetland restoration projects in the California Bay-Delta Estuary via semi-structured interviews with 59 project developers and regional restoration policymakers, funders, and managers across nine case study projects. Findings suggest common challenges emerge around conflicts among regulatory authorities and insufficient funding for post-project stewardship. We recommend potential solutions to address key barriers and increase the pace of wetland restoration. Adaptation in developed coastal estuaries worldwide increasingly requires nature-based solutions like wetland restoration; such a framework is imperative to diagnose barriers and identify interventions that can increase investment in these complex social-ecological systems.

Rising water bills across the U.S. underscore the need to understand the factors that contribute to disparities in local system bills. In this paper, we examine residential water bill amounts from 1,720 systems in four states in different regions of the U.S. (Arizona, Georgia, New Hampshire and Wisconsin) to (1) examine how local system bills at a constant consumption level (4,000 gallons per month or 15.14m3) for drinking water vary within and across states, as well as within combined metropolitan statistical areas (MSAs), and (2) study the relationship between local system bills and system-level characteristics. We find a high degree of similarity in median bill amounts between states but substantial variation within them at the MSA and local system scale. Our multivariate analysis suggests that municipally-owned systems are more likely to have lower water bills relative to for-profit systems, while factors such as purchasing water and having neighboring systems with high bills significantly correlate with higher water bills. Though we find that water systems with high levels of poverty tend to have higher water bills, our results also suggest that local systems that serve populations with higher levels of income inequality and higher proportions of non-White population tend to have lower water bills. These findings point to future research and data needs to better inform federal, state and local water affordability policy and underline the importance of examining and addressing water affordability at local scales.

Sea‐level rise is a “nascent subsystem” with policy actors actively developing initial policy preferences through participation across multiple policy forums in a polycentric system. This paper uses item‐response models to empirically analyze how actors, perceived problems, and preferred policy solutions are related in a latent “policy space”. We focus on California's San Francisco Bay region, where in the last decade, sea‐level rise emerged to become one of the most salient climate adaptation issues. We find that actors and policy preferences are arranged in a two‐dimensional space, with highly engaged actors more likely to consider environmental justice and ecological aspects of sea level rise. Our findings have implications for theories of nascent subsystems within the Advocacy Coalition Framework, and for understanding how a local policy subsystem develops to address and prioritize the multi‐faceted impacts of climate change.

The paper examines relationships between stormwater control measure (SCM) priorities and environmental value orientations among stormwater managers in Cleveland, Ohio and Denver, Colorado, metro regions with contrasting environmental conditions and policy contexts. While studies show that governance explains differences in broad SCM priorities, less is known about what motivates individual “street level bureaucrats” who influence decisions at the project level. Drawing from cognitive social science perspectives, this study surveyed stormwater professionals (n = 185) about primary and co‐benefit SCM priorities and environmental value orientation. Results revealed different primary SCM priorities by region: Cleveland and Denver respondents prioritized quantity and quality goals, respectively, reflecting regional context. Co‐benefit priorities correlated to two environmental value orientation clusters — “Traditional Technocrats” with relatively anthropocentric orientations and “Champions” with relatively ecocentric orientations — who were equally abundant in both regions. Findings suggest that environmental value orientation influences co‐benefit priorities, which may have implications for project level articulation of policy.

Stormwater infrastructure substantially impacts water quality and supply. In the U.S., local agency investments rely on public support from taxes or fees. Assessing individuals’ knowledge and willingness to pay helps inform potential pathways to funding and green infrastructure implementation. Using a 2018–2019 survey of 868 University of California students and staff, we analyze stormwater knowledge and willingness to pay or support public fund allocation for green infrastructure, especially natural treatment systems (NTS). Results of three separate regression models, each with a one-campus random sample and an all-campus convenience sample, show the majority of respondents supported allocating personal and campus funds for NTS. Preexisting environmental attitudes (on the New Ecological Paradigm scale) were the most common driver in nearly all models, but with inconsistent results and low explanatory power across models. Harnessing public support to increase stormwater investment may require tailored benefit messaging or other motivational frameworks, particularly in semiarid environments.

Rapidly‐growing concern among scholars and policy makers over residential drinking water affordability in the United States highlights the need to identify and assess the efficacy of potential solutions to address this problem. Accordingly, in this advanced review of the literature, we examine the state of scholarly evidence over the last 30 years on the prevalence and effectiveness of strategies to address household drinking water affordability in the United States. We classify interventions into four categories: rate structure designs, water efficiency programs, recurring bill assistance, and crisis relief. Our findings are twofold. First, the conceptual literature on affordability interventions is fairly robust, but demonstrates both tradeoffs and complementarities across the four approaches. Second, despite employing a PRISMA approach, we identify few empirical studies that demonstrate the effectiveness of affordability interventions in practice, especially the targeted approaches of recurring bill assistance and crisis relief. The literature on affordability interventions thus appears to lag considerably behind scholarship identifying and defining the problem of affordability. Accordingly, we suggest key questions throughout our review that need to be answered, thereby providing an agenda for future research on drinking water affordability solutions.This article is categorized under: Engineering Water > Planning Water Human Water > Value of Water
