hurricane sandy westchester county

Water surface elevations for the 10-, 50-, 100-, and 500-year floods are also available in FEMA Flood Insurance Studies. WebHurricane Sandy As Hurricane Sandy left a wake of destruction across the Mid-Atlantic States and New England, the U.S. Department of the Interior (DOI) mobilized resources Closure of the Parkway would affect commuter traffic as it serves as a commuter route to Hudson River villages, Yonkers and Manhattan and as a reverse commute route to Tarrytown, White Plains and other destinations in the vicinity. Figure 8: An example paved ditch to convey stormwater to an outfall location.

We only had 64 summer members all of last summer, but this summer we had almost 300. A hydrologic model will simulate the conversion of rainfall into surface runoff.

First, it would be assumed and accepted that the Saw Mill River Parkway would flood periodically.

Bridges would need to be raised to maintain required vertical clearances and culverts would need to be enlarged. The entire Parkway corridor is projected to face an increase in the frequency and magnitude of precipitation events of different return periods in the future. This reduction in discharge is a direct result of flood storage/routing in the floodplain upstream of Ashford Avenue. When the grass is overgrown and the ground is saturated from heavy rain, the grounds infiltration rate decreases. After going through these calculations, the per-event cost of moderate to heavy rainstorms was estimated at $33,016 ($2012) and that of severe storms/hurricanes was estimated at $78,853 ($2012). Drainage Inlets: 6 inlets x $4,000/inlet = $24,000, Roadway Crossing Pipes: 3 pipes x 55/pipe x $110/ft. If the roadways elevation is below a storms flood elevation, it will flood. Looking at the high estimate projections of precipitation events, the annual average number of days with over 1 inch of rainfall is projected to increase from 13 (baseline years 2000-2004) to 17 by 2050 and 18 by 2080[6]. =18,150, Asphalt for paved gutters: 8,008 CF x 0.075 Ton/CF x $200/Ton = $120,120, Asphalt: 195 CF x 0.075 Ton/CF x $200/Ton = $3,000, Bioswale Const.

The Parkway extends for 29 miles through Westchester County, New York, beginning at the border of Westchester County and the Bronx as a continuation of the Henry Hudson Parkway, and terminating at an interchange with Interstate 684 and New York State Route 35. The water level in the basin is set by the low flow orifice, typically part of a metal or concrete structure called a riser. Debris and the shape of the river bed are both primary providers of flow resistance. Asphalt paved ditches have little potential for erosion, thereby reducing maintenance required for surrounding areas as compared to the existing vegetated ditches, which require more frequent maintenance (e.g., mowing and periodic cleaning). We have a brand new boardwalk at Playland, and things are back to normal. WESTCHESTER, N.Y. Hurricane Sandy is expected to bring life-threatening storm surge flooding to coastal areas, according to the National Weather Service. Source: The construction costs were calculated with unit prices based on the New York State Department of Transportation Pay Item Catalog (PIC), which includes regional and statewide average awarded price history as soon as a project has been awarded. WebThe Hudson Valley/ Westchester County Region has nine NY Rising communities distributed over three counties Orange, Rockland, and Westchester.

The agreements come on the heels of 25 previous Sandy formed in the central Caribbean on October 22, 2012 and intensified into a hurricane as it tracked north The most vulnerable river crossings and nearby segments of roadway would be made resilient to overtopping (short of raising the roadway), and embankments and other geotechnical structures in the area of flooding would be made resilient to erosion. P. Astorino.

This proposed adaptation strategy is the same for both 2050 and 2080 scenarios.

This process can be further complicated with impacts to historic and cultural resources. Starting Tuesday, Nov. 27, the multi-purpose Hurricane Sandy disaster recovery center in White Plains will have new hours of operation. Chapter 8 of the NYSDOT Highway Design Manual specifies that highway storm drain systems should have a design life and anticipated service life equal to 70 years. However, they do require periodic crack sealing and must be kept clean of sediment and debris to avoid becoming a vegetated ditch. Watershed Characteristics: The complexity of the Saw Mill Rivers watershed varies by location and plays a role in triggering riverine flooding events. As noted in previous sections, a lifecycle cost comparison of these adaptation alternatives can provide further insight into the overall costs and benefits of each alternative. WHITE PLAINS, NY: Westchester County Clerk Timothy C. Idoni wants to reassure Westchester County residents and business owners not to worry about replacing vital records such as deeds and mortgage Proposed changes within the Saw Mill River floodplain would require a Floodplain Evaluation Report to be prepared and submitted to NYSDOT.

See Figure 1 for a context map of all 10 study areas, with the Saw Mill River Parkway study area highlighted in red. With a detention basin, the orifice level is at the bottom of the basin, and therefore all the water is eventually drained from the basin and it remains dry between storms. Given that this strategy recommends modifying drainage design guidelines, this strategy is only applicable to future drainage systems or existing systems subject to significant modification.

HURRICANE SANDY IMPACT ON WESTCHESTER COUNTY AND REAL ESTATE. Hurricane Sandy caused unprecedented damage to the county when it struck Westchester on October 29, 2012, with hundreds of homes impacted, many businesses damaged, and three deaths. This adaptation strategy is an alternative to the adaptation strategy on asphalt ditches described above. For disadvantaged populations with access to personal vehicle, the impacts of closure to the Parkway may be higher, as closure will result in additional time delays and costs. Truck traffic is not permitted on this portion of the Saw Mill River Parkway; therefore AADTT is not applicable to this analysis. The storm drainage system on the Saw Mill River Parkway uses a design that was commonly used for roadways of the same era, but is not commonly used in the new construction of roadways today. The engineering informed adaptation assessments conducted for the Post-Hurricane Sandy Transportation Resilience Study in NY, NJ, and CT, focus on specific facilities in specific locations, and each of the assessments acknowledges and accounts for the local aspects of the assets.
Hurricane Sandy rolled through Westchester County two years ago this October, leaving a trail of devastation that the governors office estimated cost the county and its residents upwards of half a billion dollars. The segment of the Parkway that experiences the most critical flooding is in Pleasantville, and this segment is currently being reconstructed to address it. DOT, 2009, http://nhts.ornl.gov/tables09/fatcat/2009/avo_TRPTRANS_WHYTRP1S.html. It is assumed that this strategy can prevent the same adverse mobility-related and economic impacts, as the ones that can potentially be prevented by the strategy which proposes improvements to the drainage system via asphalt ditches. The 0.2 mile segment of the Saw Mill River Parkway being analyzed in this assessment is a very small portion of a large corridor, and a riverine analysis needs to be performed at a watershed scale. Public outreach and coordination will need to be performed and all towns will be involved in the decision making process. Practitioners should exercise care in applying the lessons learned directly to these and any other facilities, Figure 1: Context Map for Ten FHWA Study Areas (Saw Mill River Parkway in Red).

The projections are generated from two types of model simulations: the North American Regional Climate Change Assessment Program (NARCCAP) simulation and the Coupled Model Inter-comparison Project Phase 5 (CMIP5) simulation. Another feasible strategy at the watershed level is to construct temporary floodwater storage facilities in the watershed to collect storm water and slowly release it at a controlled rate to prevent flooding and erosion downstream. Watershed-level (discussed in Section 6.1). During Hurricane Sandy, the Middlesex County Utility Authority lost power to its water utility intake pump. The elevation of the orifice in the riser is selected to release small amounts of water as needed to maintain the desired water level. For example, the segment was closed to traffic six times for 2-5 hours in 2011 and 5 times in 2010 due to a few inches flooding. The ground cover/development (e.g., previous grass or impervious pavement), average basin slope, basin response time (time of concentration[2]), and availability of flood storage in the watershed affect the amount of storm water runoff reaching the river. We financed the restoration ourselves and immediately gathered a crew of people to put Humpty Dumpty back together againwe felt an obligation to open on schedule for the following beach season. NEW YORK As part of an ongoing probe of high gasoline prices in the wake of Hurricane Sandy, Attorney General Eric T. Schneiderman today announced that he has.

Consumers who lost telephone, cable, satellite or other services due to Hurricane Sandy may be entitled to credit or a waiver of extra fees from their providers. These specifications can be determined once calculations for a conceptual design have been carried out. On November 6, 2012, power was restored. This strategy recommends that instead of asphalt ditches, bioswales replace the existing unpaved shoulders to move stormwater away from the Parkway.

This system can provide the same flow capacity as an asphalt swale for flood events, while also providing ancillary benefits such as attenuating the peak flow through infiltration and storage in the soil, providing an aesthetic amenity, and improving water quality in downstream receiving waters.

The cost of updating design guidelines is assumed to be approximately $500,000. It was assumed that the additional distance traveled (in miles) due to the detour is 3 miles per vehicle.[20].

The NARCCAP and CMIP5 simulations are based on the A2 and RCP-8.5[7] future global greenhouse gas (GHG) emissions scenarios, respectively. State and Federal permits are required when working within floodplains. For Westchester County, Hurricane Sandys Effects Still Felt.

John Cornelius, a business analyst at the Small Business Development Center in Yonkers, reminds us that even two years later, some people are still struggling: Development centers like ours are the face of the HUDs New York Rising program, which offers small businesses grants of $50,000 and low-interest loans for disaster recovery, and its still very active. These two return periods were selected because the storm drainage system at Saw Mill River Parkway should be designed in accordance with NYSDOT standards, and Chapter 8 of the NYSDOT Highway Design Manual specifies that storm drainage systems on interstates and other freeways be designed for a 10-year storm frequency, with locations at sag vertical curves (curves that connect descending grades forming a bowl or sag) designed for a 50-year storm frequency. There are a number of transit alternatives including Metro-North Railroad and the Bee-Line Westchester Bus System that provide direct service to Yonkers, Scarsdale, the Bronx, and Manhattan. The maintenance requirements would be the same as existing requirements; however, there would be more structures to clean and maintain. The Saw Mill River flows north to south and is immediately adjacent to the Parkway. WHITE PLAINS, N.Y. The White Plains Daily Voice is leading into the new year by counting down, in no particular order, the top 10 stories from 2012. The regions Copies of Deeds and Mortgage Documents can be obtained from Westchester County Clerks Office. New York: People are lifting their houses and taking extra precautions to prevent possible damage. [23] This cost includes the cost of conducting a background study and following other NYSDOT procedures for updating design guidelines. There are 17 block groups in the southern part of the City of Yonkers west of the Parkway in which between 23 and 38 percent of the population is below the poverty level. For this high planning-level design, there was assumed to be no difference in cost for solutions designed for the 2050 or 2080 scenarios. These implications increase the cost associated with this strategy. A New York State Department of Environmental Conservation (NYSDEC)/US Army Corps of Engineers (USACE) Joint Application Form for a wetland permit must be approved. FEMA Flood Insurance Studies and Maps are a public source for flood hazard information and indicate an areas flood risk. [9] Mileage and time estimates are based on Google Maps. This assessment identified existing and projected vulnerabilities of a 0.2 mile segment of the Saw Mill River Parkway to moderate to heavy rainstorms. This strategy could potentially prevent adverse impacts on mobility and the economy from disruptions to the Parkway, which would otherwise occur during moderate to heavy rainstorms. WebHurricane Sandy (unofficially referred to as Superstorm Sandy) was an extremely destructive and strong Atlantic hurricane, as well as the largest Atlantic hurricane on Weve properly insured ourselves, repositioned some equipment.

FHWA partnered with State Departments of Transportation and local transportation agencies to understand the lessons learned from Hurricanes Sandy and Irene, and develop feasible, cost-effective strategies to address the vulnerabilities of transportation assets to the projected impacts of climate change. It cost us about half a million dollars. The increase in drainage area results in no significant increase in peak discharges in the Saw Mill River between Ashford Avenue and its confluence with Hudson River. [21] Westchester County, Bee-Line System Map, http://transportation.westchestergov.com/images/stories/pdfs/2014SysMapEng.pdf.

This strategy could potentially prevent adverse impacts on mobility and the economy from disruptions to the Parkway, which would otherwise occur during moderate to heavy rainstorms. We decided it was time to [protect our property] ourselves.

Next, data collection, including field surveys, are needed to analyze the causes and sources of flooding to be controlled. The flood elevation relative to the top of roadway elevation will indicate if the roadway will be inundated with water. It should be noted that while a detention or retention basin would be appropriate to mitigate the flows of local drainage entering the Saw Mill River, it may not be an adequate solution to mitigating flows during moderate or high intensity storms, which typically require significantly larger storage ponds. The system must meet stormwater quality regulations, and coordination would be required with the New York State Department of Environmental Conservation to obtain the necessary water quality certification.
