Green Stormwater Infrastructure Fundamentals and Design Discover novel stormwater control measures to make for a greener tomorrow! The protection of our aquatic resources is growing in importance as the effects of climate change and continued urbanization are felt throughout the world. While most rain that falls onto vegetated spaces infiltrates the soil, rain that falls onto impervious surfaces will not, increasing downstream flooding and erosion and causing impaired water quality. Impervious surfaces such as road infrastructure, rooftops, and parking areas all increase runoff and mobilize many pollutants that have deposited on these surfaces that are then carried into our waterways. Proper management of this stormwater through green infrastructure is essential to address these challenges and reduce the environmental and ecological impacts brought about by this runoff. This book brings into focus resilient stormwater control measures (SCMs) for the reduction of stormwater flows and associated pollutants that can detrimentally impact our local environmental and ecological systems. These interventions are green infrastructure based, utilizing natural hydrologic and environmental features using soil and vegetation to manage stormwater. These technologies include water harvesting, bioretention and bioinfiltration, vegetated swales and filter strips, permeable pavements, sand filters, green roofs, and stormwater wetlands, among others. The basic science and engineering of these technologies is discussed, including performance information and best maintenance practices. Green Stormwater Infrastructure readers will also find: Research-informed resilient SCM design fundamentals Diagrams developed by the authors to enhance understanding Case studies to illustrate the points elucidated in the book End-of-chapter problems with a separate solutions manual Green Stormwater Infrastructure is an ideal resource for environmental, civil, and biological engineers and environmental scientists in the consulting field.

This book is also a resource for practitioners and professionals developing their work in architecture studios, engineering companies, local and regional authorities, water and environmental industries, infrastructure maintenance, regulators, planners, developers and legislators.

The Urban Street Stormwater Guide begins from the principle that street design can support--or degrade--the urban area's overall environmental health. By incorporating Green Stormwater Infrastructure (GSI) into the right-of-way, cities can manage stormwater and reap the public health, environmental, and aesthetic benefits of street trees, planters, and greenery in the public realm. Building on the successful NACTO urban street guides, the Urban Street Stormwater Guide provides the best practices for the design of GSI along transportation corridors. The state-of-the-art solutions in this guide will assist urban planners and designers, transportation engineers, city officials, ecologists, public works officials, and others interested in the role of the built urban landscape in protecting the climate, water quality, and natural environment.

Stormwater Design for Sustainable Development presents an integrated approach to controlling stormwater runoff quantity and quality. With a focus on low-impact development, the book describes how to incorporate existing topography and drainage channels, curvilinear street layout, building locations, utilities, and proven best management practices, blending them all into a pleasing whole.

TRB's Airport Cooperative Research Program (ACRP) Research Report 174 defines and discusses green stormwater infrastructure (GSI) management strategies, a relatively new approach to regulation compliance. As more airports are proactively incorporating sustainable practices in all aspects of their operations, federal and state regulatory agencies are also promoting GSI strategies to comply with water regulations and requirements. Volume 1: Primer is written for the airport manager, planner, and engineer seeking to understand stormwater management and how GSI can comply with regulatory standards and requirements along with other benefits. Volume 2: Guidebook assists airport staff with evaluating the applicability of a GSI strategy and how to select an appropriate GSI strategy.

Urbanization has led to increased impervious surface area in watersheds globally, contributing to increased stormwater discharge and nutrient loading to aquatic ecosystems. Freshwater ecosystems like Lake Champlain have been negatively impacted by harmful algal blooms driven by excess phosphorus (P) loading. Additionally, salinization from chloride (Cl-) in road salts used in developed areas is a growing concern for freshwater ecosystems in cold climates. Green stormwater infrastructure (GSI) is a best management practice (BMP) intended to mitigate increased runoff and nutrient loading. Many states require the incorporation of GSI in new development plans, but better guidance is needed for the materials used in GSI to achieve desired water quality goals. Two popular GSI types are subsurface gravel wetlands and bioretention cells; however, measured performance of these GSI types has been variable for P. In my first thesis chapter, I examine the effects of different materials on P and Cl- dynamics in subsurface gravel wetlands and the effects of Cl- on two wetland plant species. My results demonstrate that some materials being used in subsurface gravel wetlands may lead to increased soluble reactive P leaching, compromising water quality goals. Chloride data suggest no significant retention by gravel wetland substrates, and that plant sensitivity to field Cl- concentrations differs by species. In a second study, I tested several drinking water treatment residuals from EPA Region 1 for their P removal capacities in the context of bioretention cells. Results illustrate variable, but largely high P removal capacities, with arsenic leaching below the threshold of concern, providing additional evidence that these materials could broadly support enhanced P removal by bioretention systems.

The impervious surfaces of built landscapes create stormwater runoff that causes water quantity and quality problems downstream, upsetting natural hydrology and harming aquatic ecosystems. Green stormwater infrastructure (GSI) includes practices that reduce the amount of stormwater runoff and the pollutants it carries utilizing plants, soils, and other materials to capture, store, reuse, infiltrate, evapotranspire, and filter stormwater. GSI helps to restore developed landscapes, mimicking natural hydrologic processes and providing important water treatment functions as well as beneficial green spaces in urban areas. However, there are many challenges associated with the implementation and maintenance of GSI in our communities and cultures. This research explores the human side of implementing GSI, investigating current maintenance capacities in rural and urban settings, and exploring multifunctional benefits of GSI to provide both biophysical and cultural ecosystem services (CES). Research goals include characterizing the current state of GSI implementation and maintenance in municipalities in the State of Vermont (USA) and eliciting lessons that can inform GSI design practices and policies. Multifunctional GSI design objectives that provide and enhance CES are described, revealing opportunities to instill values and a sense of stewardship for the health wellbeing of people and ecosystems. The first chapter provides relevant topical background to set the stage for the latter two chapters. The second chapter analyzes results from a survey of municipal officials in Vermont that occurred as part of NSF-EPSCoR-funded Basin Resilience to Extreme Events project research on stormwater management. The survey included questions about GSI and maintenance practices in place and perceptions of visual appeal and ability to maintain bioretention systems shown in landscape visualizations. Results show that visual appeal and perceived maintainability of vegetated bioretention practices do not appear to be significant barriers to adoption and operation, but stormwater policy and funding are shown to be both significant barriers and solutions to implementing and maintaining GSI in Vermont municipalities. Additionally, urban and rural towns provide very different contexts for implementing and maintaining GSI in Vermont and characteristics of development patterns and maintenance capacity should be considered in policy, regulations, outreach, and education. The third chapter offers a literature review, guided by a CES framework, of design elements that can be included in GSI to create multifunctional urban green spaces. CES categories of aesthetic, recreation, education, sense of place, social capital, and stewardship benefits framed a set of design elements, principles, practices, and documented benefits to guide multifunctional design of GSI. Findings include the importance of participatory processes to elicit diverse landscape values, visible water pathways, biodiversity, spaces for creative use, accessibility, interaction with water, interpretive signage, and artful and biophilic design features to enhance feelings of preference, pleasure, relaxation, learning, connection, and inclusion. The health and wellbeing of water and people must be integrated into the design of GSI for cities to be ecologically functional and culturally meaningful to their populations.
