Creating Resilient Cities: Strategies and Solutions Robert Bailey, P. E. Executive Vice President, CH2M City Solutions Brian Gackstatter, P. E. Vice President, CH2M New York

What does resilience mean? Long-Term Water Scarcity Sea-Level Rise Extreme Weather Integrated Stormwater Long-Term Water Scarcity – [follow on from intro] Sea-Level Rise: Hybrid infrastructure solutions across a diverse range of applications to address the effects of sea-level rise: coastal protection, flood mitigation, land use and transportation planning, etc. Extreme Weather: City area and capital planning to develop hybrid infrastructure solutions, adaptive measures and tactical response plans in light of extreme weather events: drought and / or flooding Integrated Stormwater: Comprehensive management of stormwater system design and integration of stormwater infrastructure within broader city water network, transportation structures, and development initiatives Mayors Can and Should be Resilience Thought Leaders!

A challenge to think differently… Take an integrated, solutions- based approach Embrace decision and risk management tools and processes Creatively aggregate funding sources Challenge audience to think about resilience differently (not just reuse): Take a leadership role in creating more comprehensive solutions Embrace new and rigorous tools and processes Consider aggregate funding models Turn resilience into competitive advantage …to turn resilience into competitive advantage

Los Angeles Integrated Solutions to Improve Resiliency City of Los Angeles and their water journey Of course, Southern California’s drought response has captured media attention lately, but we started working with Los Angeles proactively on an Integrated Resources Plan almost 20 years ago. The many-year process featured significant community engagement, and included workshops, tours, education and technical review.  It also included concepts originated by stakeholders, who represented more than 4 million people. The outreach program was presented in easy to understand concepts, and delivered results that citizens and ratepayers could identify with.  For example, Los Angeles was able to defer some construction costs due in part to successful water conservation; and maintained reasonable sewer rates through prioritizing capital improvements and debt restructuring.  In addition, the program reduced sewer spills and odors by 83%.  Building that kind of community capital is especially important before a crisis hits.   For the past 5 years, CH2M has been supporting the City to assess vulnerability to extreme climate events. Our work involved a system-wide assessment of all of the City’s wastewater, stormwater and solid waste infrastructure. The climate risk and resiliency assessment addressed impacts to critical infrastructure and operations from drought, sea-level rise, flooding due to extreme rainfall, blackouts due to increased energy demand with temperature increases, wildfires, high winds and earthquakes (with subsequent landslides and liquefaction or flooding from tsunamis). As a result of the system-wide assessment, specific facilities were identified and prioritized for detailed, site-specific analysis. To date, a total of 12 facilities have been investigated with specific recommendations to improve extreme climate resiliency to be incorporated into the City’s capital improvement planning (CIP) process.

Miami Beach/Dade County Climate Change Resilience Planning and Facility Hardening Options Miami Ocean Outfall Legislation Program – Climate Change Resilience CH2M is providing program management for the Miami-Dade County Water and Sewer Department’s (WASD) $3.3 billion Ocean Outfall Legislation Program. The 11-year program (with 28 capital projects) is the culmination of a regulatory mandate by the Florida Legislature to stop all wastewater discharge to the ocean by 2025. This task included assessment of projected climate change for key climate variables (sea level rise, precipitation, and wind); modeling the extent of inundation due to sea level rise, storm surge, and extreme rainfall for a range of scenarios based on the service life of wastewater facilities; evaluation of risk to those facilities from the different climate change scenarios; and the associated costs of protecting facilities. Based on those analyses of costs versus risk, CH2M facilitated a series of workshops with WASD staff and design consultants to select design criteria that specified flood control elevations and facility hardening options, which were documented in a “Design Guide for Hardening Wastewater Facilities against Flooding from Surge, Sea Level Rise, and Extreme Rainfall.” These measures are now being used by all of WASD’s consultants and are undergoing revision and enhancements as lessons are learned from each design effort.

New York City New York City - Super Storm Sandy In the aftermath of Superstorm Sandy, we worked with New York City DEP and New Jersey and contributed to a comprehensive recovery plan, which resulted in the award-winning NYC Wastewater Resiliency Plan. We see this as a strong blueprint for other coastal areas, because the Plan is, in our opinion, among the most detailed and comprehensive assessments in the world of the risk climate change poses to infrastructure. Based on quantified impacts of climate change and population growth on the city’s sewer, drainage, and wastewater systems, the study evaluated each asset to see how storm surge under future sea level rise scenarios would be impacted. The study was the first of its kind to assess coastal flooding risks under future sea level conditions, and while it is hugely beneficial to New York City, it will also serve as a national model for other cities to consider as they plan for future storms.
