Since the topography of the Parkway is flat, the ditches and pipes of the drainage system will be flat. According to SHPOs Environmental Review Program, projects adjacent to NY State parkland should coordinate with the Environmental Management Bureau for approval. [This year was] a whole different ballgame. Either way, attendance at Playland was way down in 2013 [people didnt know it was open], and it had a damaging effect on our business. When the grass is overgrown and the ground is saturated from heavy rain, the grounds infiltration rate decreases. WebHurricane Sandy was the 18th named tropical cyclone of the 2012 Atlantic hurricane season (June 1 - November 30).
WebThe Hudson Valley/ Westchester County Region has nine NY Rising communities distributed over three counties Orange, Rockland, and Westchester. The magnitude of precipitation events in the Parkway corridor is also likely to increase based on projections developed by the Northeast Regional Climate Center (NRCC) at Cornell University for the Dobbs Ferry, NY location. Intense Rainfall Events: During a storm event, precipitation and storm water runoff increase the volume, as well as peak flows in the Saw Mill River. US 9 (Broadway) is another detour route to the west, although it has significantly less excess capacity. 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. Furthermore, there are 11 block groups in the same vicinity in which between 38 and 58 percent of the population is below the poverty level.

Cumulatively, these floodplain storage locations lead to the reduction of peak discharges significantly in downstream reaches. 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. WebHurricane Sandy (unofficially referred to as Superstorm Sandy) was an extremely destructive and strong Atlantic hurricane, as well as the largest Atlantic hurricane on
For Westchester County, Hurricane Sandys Effects Still Felt. The time of the detour is 5 minutes without traffic; however, due to the storm events and additional traffic on the alternate route, a time penalty of 80 percent was applied to arrive at the estimate detour time of 9 minutes per auto.
Based on the anticipated service life of storm drain systems, it is proposed by the project team that end-of-century precipitation projections be considered in proposed improvements to the existing drainage system at the Saw Mill River Parkway segment. 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. The proposed project must also be submitted to FEMA and upon review, FEMA may issue a Conditional Letter of Map Revision (CLOMR)[24] and/or Letter of Map Revision (LOMR)[25].
Westchester County Disaster Recovery Fund Distributes Hurricane Sandy Relief Grants Co-Communications, Inc. , Neighbor Posted Tue, Jun 18, 2013 at 10:35 am ET There was a client base here before, but, when we reopened eight months after the storm, it was very tough to rebuild those relationships. Hurricane Sandy School Closings Updated 4:45 p.m. Sunday: Based on information received this afternoon from Southern Westchester BOCES, the following schools will be closed on Monday.
Another task to be completed at the beginning of the project is land acquisition. Hundreds remained without power as long as two weeks after the storm. [3] There are likely over a hundred bridges on the river. The Parkway segment experiences flooding due to the inadequate capacity of its drainage system to divert rainwater, and also due to additional floodwater overflows from the adjacent Saw Mill River. [17] The per-minute cost for total traffic impacted for both types of events was then multiplied by the number of minutes per delay to capture to economic cost for all vehicles impacted for the length of the delay. The cost analysis for this strategy is based on a high planning-level design and only includes capital costs.
What you should do: Monitor storm's progress on radio or TV. Figure 11: Historical and Future IDF Curve for 50-Year Return Period. 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. The agreements come on the A bridge with an inadequate opening height above a riverbed can become inundated when the water elevation rises due to a storm event. For a moderate to heavy rainstorm event, AADT was divided by 24 hours to derive an hourly traffic count and was subsequently multiplied by the 3.5-hour closure. 2014. Emergency Alert Sign-Up; Bee-Line Rider Alerts; Severe Weather; 211 For Non-Emergencies; Indian Point Safety This block group is located north of Parkway segment evaluated in this assessment, and commuters in this block group going south towards New York City would be impacted if the segment is closed, assuming they use the Parkway. According to SHPOs Environmental Review Program, projects adjacent to NY State parkland should coordinate with the Environmental Management Bureau for approval. However, they do require periodic crack sealing and must be kept clean of sediment and debris to avoid becoming a vegetated ditch. As a first step in this analysis, the 2012 AADT (55,129[13]) was utilized to calculate the total traffic impacted over the duration of the closure for each event. As a next step after the development of the Master Plan, detailed design/feasibility studies for each proposed strategy including a cost benefit analysis could be conducted. 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. The transportation network that includes the Saw Mill River Parkway exhibits some degree of adaptive capacity. This assessment identified existing and projected vulnerabilities of a 0.2 mile segment of the Saw Mill River Parkway to moderate to heavy rainstorms. 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).
State and Federal permits are required when working within floodplains.
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.
Mapping Hurricane Sandys Deadly Toll. While an expensive option, it would effectively remove roadway infrastructure from the floodplain, specifically downstream of Lawrence Street where the water surface elevations during specific storm events go over the bridge elevations, and flooding concerns are among the most significant along the different segments of the roadway. New Yorks State Historic Preservation Office (SHPO) helps to identify and preserve historic, archaeological, and cultural resources. Hurricane Sandy facts and information.
Other contributing factors are described below.
For example, when there is a blockage in the river, water is not effectively transported and is stored upstream of the blockage, resulting in reduced downstream flows. The cost of updating design guidelines is assumed to be approximately $500,000. The build-up of debris at bridge and culvert openings further constricts the rivers flow.
The majority of the people were working with are up and running again, but theyre not at the level they were., John Cornelius, a business analyst at the, Life Lessons, Learned In Westchester (At Any Age), Think Parenting Isn't Fun? These specifications can be determined once calculations for a conceptual design have been carried out. [9] See Section 5.2 for an analysis of the economic impacts of this detour distance and delay time. Undersized culverts can create a bottleneck, restricting the rivers flow, resulting in flooding when the water cannot pass through the culvert and is diverted. The five new settlements are with three stations in Westchester County and two stations in Suffolk County. An existing curb opening on the Saw Mill River Parkway in need of maintenance is shown in Figure 7. This total cost includes approximately $790,000 of construction costs. The second most flood-prone segment is directly south of Lawrence Street, identified as segment MP201.2 MP201.4[1] (See Figure 2). The project began in April of 2014, and its nearing completion now.. [20] It is likely that some share of vehicles that would normally travel on this segment of the Saw Mill River Parkway would not use the assumed detour route and could have a shorter or longer detour. My partner and I leased it from the original owner and replaced or repaired everything. The five new settlements are with three stations in Westchester County and two stations in Suffolk County. The proposed drainage system would not need stormwater quality treatment devices prior to discharging to the Saw Mill River. It is estimated that construction of the asphalt ditches would take approximately six months; however, the design process and permit application process must take place prior to construction and could take several years depending on the agencys ability to find the funding, and carry out the design process. Inadequate bridge openings for a storm event can be identified where the flood elevation is above the bottom of the bridge, causing floodwaters to pond upstream of the crossing. This strategy could potentially prevent adverse equity-related impacts from disruptions to the Parkway (see Section 5.3), which would otherwise occur. The proposed updates to the drainage design guidelines would most likely increase the number of drainage structures needed at a particular location in comparison with the number of existing structures. 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. The curb openings get blocked with debris and the rainwater ponds, flooding the Parkway. The engineering informed adaptation assessments conducted for the Post-Hurricane Sandy Transportation Resilience Study in NY, NJ, and CT, focus on specific On November 6, 2012, power was restored.
Local EOCs will request state assistance if needed. This assessment examines the drainage system of the selected Parkway segment, but it does not address the contribution of overflows from the Saw Mill River to flooding at the Parkway.
Shawn Dyer, Managing Partner of the Tennis Club of Hastings, saved a flagging business struggling to get back on its feet: After Hurricane Sandy, the Har-Tru on the tennis courts was completely washed away; the air structures were covered in mud from being underwater; the deck overlooking the Hudson River was gone. The time of the detour is 5 minutes without traffic; however, due to the storm events and additional traffic on the alternate route, a time penalty of 80 percent was applied to arrive at the estimate detour time of 9 minutes per auto.
