Description
1) Maximization of Added Value for Living Shorelines
In 2017, the DC Department of Energy and Environment conducted a cost-benefit analysis (CBA) to support its proposed living shorelines in Buzzard Point. The CBA compares three living shoreline conceptual designs with different levels of protection: (1) no flood protection, (2) up to a current 100-year flood level, and (3) up to a future 500-year flood level. Through collected data for hydraulic modeling, risk mapping and identification and quantification of added values and co-benefits, the CBA concludes that the 500-year protection would provide a better socioeconomic business case in the long run. The CBA illustrates that the added values to society, which are often overlooked, are a very important factor in the business case. In order to maximize the added values, the proposed engineering designs need to deliver more than just flood protection. The session will highlight that planning and designing must be integrated in early phases in a way that local needs, opportunities and visions are incorporated into the engineering design. The session will explore what we mean, when we talk about livability, and the process of maximizing a multi-purpose green infrastructure flood protection design through livability and design integration

2) Green Infrastructure retrofits in New York City Parks
The New York City Parks Green Infrastructure Unit, in partnership with the New York City Department of Environmental Protection, has initiated a project to construct dozens of green infrastructure retrofits within existing parks by 2020. These parkland sites will each receive at least one of four practices including rain gardens, permeable pavement, permeable pavers, and subsurface infiltration systems. A number of these park practices will also receive storm water captured from adjacent streets. This presentation will highlight the planning and accelerated design progress for this large initiative and the challenges of creating green infrastructure retrofits in existing parkland. It will also discuss the protocol that was developed to identify suitable park sites and the extensive internal and external coordination that was required to design each site.

3) Grey to Green to Smart: The Next Generation of Urban Stormwater Management
In this presentation, we aim to channel the experience of two professionals, each with their own unique industry expertise, to help attendees navigate the 21st century problem of crumbling grey infrastructure and its inability to effectively manage volume stormwater in urban settings throughout the United States. This problem starts with the general limitations of combined sewers and/or grey infrastructure. Upon breaking down the basics of stormwater management in an urban environment, it's simple to see why we have these issues. Massive webs of tunnels and pipes are the main conduit to manage stormwater for large urban areas. Regardless if it is a combined sewer system or an undersized separated system, the issue most often comes down to a simple lack of volume storage capacity. Smart controls, or smart valves, can double or triple the capability that green infrastructure has in detaining stormwater. Learn how the integration of grey and green stormwater management systems with smart valve technologies is creating a stormwater management model that can outperform current urban stormwater management systems. This presentation explores how to best manage urban stormwater for a fraction of the cost of digging new tunnels and adding antiquated grey infrastructure to
