Purpose
The destruction wreaked by Hurricane Sandy and global sea level rise shed light on the importance of developing infrastructure that will reduce flooding damage and counter tidal erosion in New York City. This tool is meant to aid city employees in pinpointing the conversion of lots of land into salt marshes, which are an effective means of reducing tidal erosion, while also displaying its associated costs and benefits. It is also meant to inform citizens on the flood risk levels in New York City, which could impact their daily lives.
What is NYC Coastal Flooding Planner
NYC Coastal Flooding Planner is a WebGIS application that provides visualization and analysis functionality for coastal marsh data, which includes SLAMM model results, a Social Vulnerability Index, PLUTO land-use data and census tract-level demorgraphic data.
How to Use
- Supplementary Functions
button will show an address list. Clicking on the address will fly you to the pre-defined area on the map. These areas are selected based on the coastal marsh cluster areas
button will show a gallery of basemaps. If you want to go back, click and select
[Original Basemap]
button control the map showing. It will popup a map layer tool box once you click it
- Layer Selection
To understand how to use this function, you need to understand what data we are using. Click to see the Dataset structure in this project
You might also want to see what is SLAMM, if you don't understand what either [deterministic] and [Uncertainty] mean
Orange text means the button has been selected and is current
Such as [deterministic] means a deterministic layer is shown. Why it does not show anything? Don't worry, to make it show the layer, you have to specify the type and time .
e.g.:[deterministic] + [Low] + [2025] =[deterministic result at low sea level rise rate in 2025]
e.g.:[Uncertainty] + [New Coastal Marsh] + [2040] =[Uncertainty result(New Coastal Marsh) in 2040]
e.g.:[Medium] + [School] + [2085] =[The inundation result of school in NYC at medium SLR rate in 2085]
Use the Animation button see the change of inundation status of infrastructure across time
Confused by the color? click 
to see the Legend of layers you added.
Click [Parking lot] and [SVI & Census Tract] to show those layers as well.
You can use the [PLUTO Opacity slider] to show the underlying PLUTO layer. Click back to to see the opacity change
[Clean Selection] sets everything back to default. Warning: If you want to see this panel again, click [Clean Selection]
- Query & Filter By Drawing
button open a drawing tool box for you to interact with the data with any shape you want. Choose one of 
to draw on the map. Double click to end the drawing. The geometry drawn by you will update this dashboard with relevant statistics in that area.
- Dashboard Visualization
The chart's visualization is based on the data queried by the app according to the [Spatial Relationship you select] Try different choices and the buffer slider to see how it changes
You might notice that some dashboards charts do not show. That is because you are only querying the underlying layer now. [Map PLUTO] and [SVI Census Tract] are two underlying layers you can query at any time
Try to add [deterministic] and [Ucertainty] and draw a geometry on it to see the charts change.
- Troubleshooting
1.Reload the webpage if the app dies
2.Displaying only one layer from (deterministic, uncertainty) each time will give you the best result. Displaying them together will slower down the app
3.Animation is set to have a 4 second interval if you show deterministic results on the map. 1 second if it displays point infrastructures only
4.If you draw a ploygon but some charts do not show up. It might be because you did not choose to display deterministic or uncertainty and it might because there is no data to be queried in the area you selected.
5.Zooming in to a smaller area will make deterministic and uncertainty results show up faster
How the Flooding Planner was built
The layout framwork of the tool is built by using dojo the Map and function inside the map are built by using Arcgis Javascript API. We used ArcGIS online portal to host all of our data, which have already been cleaned. The charts in the dashboard are built by d3.js and chart.js. The tool website is generated using github page.
Who we are
This tool was developed by Andrew Hill, Chang Du, Haoming Yang, Sean Andrew Chen, and Yushi Chen for our NYU-Center for Urban Science and Progress Capstone Project titled “Tidal Wetland Conservation Options for Long-Term Land Use Planning for Sea Level Rise” on behalf of the New York City Department of Parks and Recreation.
