2 NYC Infrastructure reconstruction challenges It is widely recognized that a significant percentage of the country's infrastructure has reached its useful life and must be replaced. This infrastructure renewal is first and foremost a serious challenge for the nation's urban areas where people, financial and cultural centers are concentrated. This presentation is an overview of some of New York City's approaches that go beyond just infrastructure reconstruction.

3 New York City Department of Design + Construction (DDC) DDC was created in 1995 to provide design and construction expertise to 23 City agencies. This centralization enables our client agencies to focus on delivering their quality services to the public. It also allows DDC to focus on our core mission which is to strive for the highest degree of engineering, architectural design and construction quality while improving the urban environment. We manage the design and construction for publicly funded city buildings and the basic infrastructure that New Yorkers routinely rely on every day. Sewers, water main and roads projects are designed and managed by DDC Infrastructure Division. Building projects are managed by DDC Public Buildings Division.

4 New York City Department of Design + Construction (DDC) created in October 1995 oversees capital projects of 23 City agencies performs design and construction services Infrastructure Division streets sewers water mains retaining walls plazas bio-retention - BMPs Public Buildings Division correctional and court facilities cultural institutions libraries firehouses police stations uses in-house resources and private consultants and contractors

11 The new Police Academy will provide training space for up to 4,000 recruits per year while satisfying the ongoing requirements of the NYPD's uniformed officers and civilian corps. The campus will consolidate the Department s academic and training facilities currently scattered across the City. The overall complex will include instructional spaces for providing immersive, scenario-based training for police personnel, indoor firing ranges, a sophisticated tactical training building, classroom and administrative space and a driver training course. The new Academy will be one of the largest environmentally sustainable complexes in New York City. College Point, Queens Est. $ 737 million

12 The Public Safety Answering Center II (PSAC II) will be a second emergency communications 911 call intake and dispatch center for the City; The new building will act as a parallel operation to the existing PSAC I in downtown Brooklyn and will augment and provide redundancy to the current emergency 911 response service; It will serve as a streamlined emergency call and dispatch center for all of the City s first responders, including the NYPD, FDNY and the Emergency Medical Services, and; will house command control centers for the FDNY and the NYPD in order to coordinate emergency response throughout the entire city at a centralized location. Hutchinson Center, Bronx Est. $583 million

15 Water Main Break Floods Flatiron District A massive water main break in Flatiron sent water cascading into a subway station at Broadway and 23rd St. late Friday morning, leading portions of the N and Q lines to be closed all afternoon. The main a 36-inch pipe dating to 1915 ruptured at 24th St. and Broadway about 10:45 a.m. Friday, February 1, 2013, flooding area streets and sending water rushing down into the subway system. The MTA says N/Q service is suspended between De Kalb and 57th and 7th or R service between Queens Plaza and Whitehall as the power has been turned off at the flooded station. Also? Expect a lot of traffic around Madison Square Park today. Massive water main break drenches a subway station in Flatiron, knocking out service on the N and Q lines for hours The break was at 24th St. and Broadway, and sent water flooding down into the subway station at 23rd St. and Broadway. Normal service has been restored normal service was restored on the N, Q, B and D lines. The R train is running on alternate lines.

20 NYC water supply system 1.2 billion gallons drinking water per day daily Serving 8 million residents of New York City plus approximately one million people living in Westchester, Putnam, Ulster, and Orange counties. This water originates as far as 125 miles north and west of the City in three watersheds, comprising 19 reservoirs and three controlled lakes, and covers a total area of almost 2,000 square miles. The water flows through aqueducts to balancing reservoirs; then into the City s approximately 7,000 miles of distribution water mains system. Up to now this water is conveyed in to the City by two tunnels, No. 1 and No. 2. Both tunnels are constructed deep within the bedrock of the City.

21 City Tunnel #3 - Summary Construction started 1970, expected completion in 2013 Total cost $6 billion Tunnel has 4 Stages with tunnel size ranging in width from 10 to 24 feet in diameter, and depth of 400 to 800 feet. Stage 1) 13 miles long, runs from Hillview Reservoir in Yonkers, through the Bronx, into Manhattan to Central Park, and under the East River to Queens. Activated in 1998 at a cost of about $1 billion. Stage 2) Consist of two sections Section 1. The Brooklyn /Queens has two distinct legs. The Brooklyn leg runs 5.5 miles from Red Hook, Brooklyn to Maspeth Queens. It will also connect with Richmond Tunnel which delivers drinking water to Staten Island. The Queens leg runs 5 miles trough Woodside and Astoria. Both legs were connected at the end of 1997 and concrete lining of both legs was completed in May Section 2. The Manhattan Section starts from Central Park south along west side and also a segment from west to east and then north across Manhattan. Tunneling, lining & shafts for this section completed in Stage 3) From Kensico reservoir to valve chamber in Van Cortlandt Park (16 miles long) Stage 4) From valve chamber in Van Cortlandt Park to Queens (14 miles long) City Tunnel #3 will allow for shutdown, repair & renovation of tunnels #1 (1917) & #2 (1936) Insure safe drinking water to NYC for the foreseeable future Filtration Plant in Croton to improve water quality

32 The lack of resiliency of our infrastructure assets was evident in October 2012 during hurricane Sandy. 2008, New York City Panel on Climate Change (NPCC) The New York City Panel on Climate Change which was convened by Mayor Bloomberg issued a report in 2009 that predicted among other climate change risks, that by 2080, due to sea level rise to nearly 2 feet as a result of global warming that the 1 in 500 year extreme weather event would occur once every 120 to 250 years and would cause coastal storm surges of 11 to 12 feet with disastrous consequences for coastal communities

33 Alert issued 10/28/12 at 11:45 AM. New York City has ordered a MANDATORY EVACUATION of Zone A the Rockaways, Hamilton Beach, and City Island.

34 Climate Change (PLANYC 2030) SANDY IMPACT AREAS Cities are at the forefront of both the causes and effects of climate change. Urban areas located on a coast like New York City face increased climate risks. GHG mitigation efforts can reduce severity of climate change but cannot completely prevent it from happening No single action can achieve GHG reduction. City s climate resilience ability to withstand and recover from extreme events and environmental changes Queens 49 Staten Island 28 Bronx 27 Brooklyn 27 Manhattan 24 ================= Total # Projects = 155

35 LOOKING AHEAD: SUSTAINABLE URBAN SITES mitigations measures of particular relevance to NYC Minimize Site Disturbance Soil, vegetation, reducing run-off; implications of laws such as SPDES, SWPPP, etc. Maximizing Vegetation: Tree planting details, green walls, low-maintenance native planting, turf alternatives Incorporate Recycled content: Pavements, site furnishings, etc. Mitigate Urban Heat Island Effect: High albedo pavements, shading techniques Water Management: Stormwater management and cleansing; Water efficient landscape techniques.

36 Climate adaptation measures* Green Infrastructure Capacity increases to drainage systems Detention systems Sea walls Tide barriers Pumping systems Street pavements Raising roadway grades Raising platform levels at entrance of critical facilities Elevating critical components of vulnerable assets Zoning and building code modifications *Parsons

37 Special Initiative for Rebuilding & Resiliency SIRR is tasked with two major challenges put forward by the Mayor in the wake of Sandy that look long-term: 1) how to rebuild locally 2) how to improve citywide infrastructure and building resilience factoring in risk due to climate change. We will be formulating community plans for East/South Shore SI, South Queens, Southern Brooklyn, Lower Manhattan and Brooklyn/Queens Waterfront, in addition to a citywide plan (May 2013).
