Much has been made of the need for cities to becomemore sustainable, particularly since for the first time in human history over half of the world’s population are urban dwellers. Cities concentrate human activities in an exceptionally powerful manner, and this includes resource use and the generation of pollution. Attention has turned towards cities for their capacity to enhance and use nature’s services – ecological sustainability – to remediate some of their own environmental impacts. Insufficient attention has been paid to the challenges of implementation of this new approach to infrastructure in an era of devolution and skepticism about government. This paper discusses these twin and interwoven questions through the lens of an on-going natural experiment, the implementation of a million tree-planting campaign in Los Angeles, CA.

Funding Water in Times of Financial Uncertainty: The Case for a Public Goods Charge in California

Stanford University | January 15th, 2015

Funding for water-related public purpose projects has become increasingly scarce in California. Utilities are facing new challenges that require additional capital while the state’s legal system has restricted the ability of local governments to raise funds. This fiscal landscape requires the water sector to find new ways to finance water-related public interest projects, including conservation and efficiency programs, monitoring and evaluation, and infrastructure maintenance and modernization. California must also generate supplementary funds for new water technology research, development, and dissemination if the state is to continue to grow despite dwindling water supplies. In recent decades, California has relied heavily on general obligation (GO) bonds to finance a variety of water-related projects. GO bonds, however, are unreliable funding mechanisms as they require voter approval if they survive the legislative process, and they can be costly in the long run as they are repaid with interest. Additionally, GO bonds violate the beneficiary-pays principle as the entire state repays a debt that benefits taxpayers in certain regions more than others. This research paper looks at a supplemental funding mechanism, a Public Goods Charge (PGC), as an additional way for California to provide for water investment in the future. In a PGC scheme, ratepayers are charged a small, usage-related fee, and the funds are subsequently allocated to public interest projects at the local, utility, state, and broader scales. This method was used to fund electricity public purpose programs in California from 1998-2011, resulting in over $5.8 billion collected by the state’s three main Investor Owned Utilities (IOUs), with additional funds collected by local Publicly Owned Utilities (POUs), for energy innovation over 14 years. Utilities and the state as a whole benefitted economically and environmentally from the increased funding for energy efficiency, renewables, and research and development. The electricity PGC helped to transform California’s energy landscape into one that includes more modern and sustainable infrastructure systems. Significant energy savings were also achieved during the PGC era.

Contra Costa County and the City of Richmond, via the San Francisco Municipal Regional Stormwater Permit (MRP), are required to develop and implement a Green Infrastructure (GI) Master Plan to reduce mercury and PCB loads in stormwater runoff from each jurisdiction. This project used GreenPlan-IT, a planning tool developed by the San Francisco Estuary Institute (SFEI) and regional partners, to identify feasible and cost-effective GI locations within the North Richmond Pump Station watershed (an unincorporated community of Contra Costa County and partial jurisdiction of the City of Richmond) to support the development of GI Plans for permit compliance.

The City of Richmond, via the San Francisco Municipal Regional Stormwater Permit (MRP), is required to develop and implement a Green Infrastructure (GI) Master Plan to reduce stormwater mercury and PCB loads. This project used GreenPlan-IT, a planning tool developed by the San Francisco Estuary Institute (SFEI) and regional partners, to identify feasible and cost-effective GI locations within the City boundary to support the development of GI Plans for permit compliance.  GreenPlan-IT comprises four distinct tools: (a) a GIS-based Site Locator Tool that combines the physical properties of different GI types with local and regional GIS information to identify and rank potential GI locations; (b) a Modeling Tool that is built on SWMM5 to establish baseline conditions and quantify anticipated runoff and pollutant load reductions from GI implementation; (c) an Optimization Tool that uses an evolutionary algorithm to identify the best combinations of GI types and numbers of sites within a study area for achieving flow and load reduction goals; and (d) a Tracker Tool that tracks GI implementation and reports the cumulative programmatic outcomes for regulatory compliance and other communication needs. 

Green Plan-IT Application Report for the East Bay Corridors Initiative

Regional planning of Green Infrastructure (GI) is an important aspect of building in or retrofitting GI and other green spaces across municipal jurisdictions. This level of planning allows for GI to be implemented according to natural boundaries and builds important partnerships across municipalities. The East Bay Corridors Initiative is a unique partnership across 13 jurisdictions, county and regional agencies, as well as community groups and businesses to plan new housing, create job opportunities, and improve parks and streets with linkages to essential services (ABAG 2016). The Initiative covers a large swath of the East Bay of San Francisco Bay, CA from Rodeo in the North to Union City in the South and focuses on Priority Development Areas (PDAs) and transportation linkages. In addition to the above focus, the Initiative will also look at opportunities for GI implementation across the Corridor. The Resilience priority within the Initiative focuses on sustainable infrastructure including regional GI implementation, green streets, and stormwater/flooding mitigation (ABAG 2016). The objective of this project was to use GreenPlan-IT, a planning tool developed by the San Francisco Estuary Institute (SFEI), to identify feasible GI locations within the East Bay Corridor footprint. Results from the application of the Site Locator Tool will be used to: 1) identify potential green infrastructure projects for the Corridor’s sustainable infrastructure planning efforts, including the development of information for municipal and regional GI Master Plans and Stormwater Resources Plans; and 2) potentially help comply with municipal Stormwater Permit requirements.  GreenPlan-IT is a planning level tool that was developed over the past five years with strong Bay Area stakeholder consultation and designed to support the cost-effective selection and placement of green infrastructure in urban watersheds through a combination of GIS analysis, watershed modeling, optimization techniques, and data visualization. Structurally, GreenPlan-IT comprises four standalone tools: (a) a GIS-based Site Locator Tool that combines the physical properties of different GI types with local and regional GIS information to identify and rank potential GI locations; (b) a Modeling Tool that is built on EPA’s SWMM5 (Rossman, 2010) to establish baseline conditions and quantify anticipated runoff and pollutant load reductions from GI sites; (c) an Optimization Tool that uses a cost-benefit analysis to identify the best combinations of GI types and number of sites within a study area for achieving flow and/or load reduction goals; and (d) a tracker tool that is used to track GI implementation and report the cumulative programmatic outcomes for regulatory compliance and other communication needs. The Toolkit package, consisting of the software, companion user manuals, and demonstration report, is available on the GreenPlan-IT web site hosted by SFEI.

This technical memo describes the purpose, functions, and structure associated with the newest addition to the GreenPlan-IT Toolset, the GreenPlan-IT Tracker. It also shares the opportunities for further enhancement and how the tool can operate in concert with existing resources. Furthermore, this memo describes a licensing plan that would permit municipalities to use the tool in an ongoing way that scales to their needs. The memo concludes with a provisional roadmap for the development of future features and technical details describing the tool’s platform and data structures. About the GreenPlan-IT Toolkit Municipalities across the state and beyond are carefully planning and implementing green infrastructure in their developed landscape to restore key aspects of the natural water cycle. Green infrastructure helps to achieve stormwater attenuation and contaminant filtration by increasing the pervious surfaces in often sophisticated ways. Additionally, green infrastructure features, as city dwellers have come to realize, demonstrate multiple benefits in addition to improving surface porosity, such as peak, volume, and load reductions, urban heat island mitigation, traffic calming, carbon sequestration, wildlife habitat, natural aesthetics, and others. The benefits are substantial, but so are the potential costs. GreenPlan-IT helps planners to make smart decisions in the types and locations of green infrastructure, minimizing effort and cost while maximizing the effectiveness of the public and private investments. GreenPlan-IT modules are focused on green infrastructure planning and assessment, including the Site Locator Tool, Modeler, and Optimizer tools. Together the modular toolkit can be used to take a city from a position of not knowing where to consider GI placement (a daunting position given the MRP C3 and C11/12 requirements), to a plan that includes a list and map of feasible locations and a map of baseline flow and pollutant load conditions, and a selected optimal set of placement locations for achieving flow and load reductions at minimal cost. Now, with the advent of the GreenPlan-IT Tracker, there is also a web based tracker for quantifying and communicating the locations, types, and treatment areas of GI installations (the outputs of all the planning efforts) and quantifying the peak flows, volumes, and loads reduced (the outcomes of all the implementation and cost expenditure that the community is asking for).

Guide for Developing Onsite Water Systems to Support Regional Water Resilience

Across the United States, urban communities face growing water challenges, from water scarcity to flooding, pollution, aging water infrastructure, and more. These challenges present risks, but also an opportunity to rethink how we manage water, including adopting circular approaches in new buildings that reduce their water footprint and improve urban water resilience. Onsite water systems, for example, collect, treat, and reuse water from onsite sources, including wastewater, rainwater, and stormwater, for non-potable water uses like toilet flushing, outdoor irrigation, and cooling. Onsite water systems have the potential to provide multiple benefits for a site, water and wastewater systems, ecosystems, and communities. They can, for example, help companies mitigate water- related risks, like water shortages that threaten to disrupt business operations, and support corporate water stewardship goals. For communities, onsite water systems can enhance water supply reliability, improve water quality, reduce localized flooding, and increase urban green space. The realization and magnitude of benefits will vary with the type of system, scale of adoption, and other context-specific factors. This guide helps site developers consider how onsite water systems can be planned, designed, and operated to provide multiple benefits, and contribute to planning and designing onsite water systems that advance water resilience, support equity, support the environment, and protect public health at the site, water system, and community scales. For each of these outcomes, the guide provides sample questions to consider, stakeholders to engage, resources to examine, and analyses to perform.
