This page provides the key materials to access, utilize and maximize use of the tool, including a downloadable desktop tool, its associated user manual, example scenario inputs and outputs, and additional useful data inputs for the desktop tool.

 

SCENARIO PLANNING TOOL

GIS TOOL: Coming Soon
Download Tool

This GIS tool assists users with developing, analyzing, and evaluating different restoration and land use scenarios in the Delta. The tool runs as a custom toolbox within ArcMap (ESRI ArcGIS). It will be available for download in early 2020.

USER MANUAL: Coming Soon
Download Manual

The User Manual provides detailed instructions on using the tool. It discusses how the tool operates, how to design a scenario, how to import other scenarios, what data inputs are needed, where to acquire these data, and how to interpret and evaluate scenario outputs. It will be available for download with the GIS tool in early 2020.

 

EXAMPLE SCENARIOS

The following scenarios have already been evaluated using the latest version of the tool. The input data for these examples can be downloaded by users and modifed to create their own scenarios. The output tool results for each scenario can also be viewed here without the need to run the tool. More scenarios will be added below as they are developed and evaluated.

Scenarios can be submitted for inclusion in the list below by filling out the online scenario upload form, which will be activated in early 2020.

Ecorestore - DRAFT

The Ecorestore The Ecorestore scenario reflects the existing and planned EcoRestore projects in the Delta (as of 1/11/19). It was developed by SFEI staff from publicly-accessible reports and maps but may not reflect the latest plans for these projects. It is not endorsed by any State agencies or project proponents. The scenario is included here to share an early draft of tool outputs, which are subject to change in the future as the input data are refined and the tool is further developed.

GUIDING DATASETS

These datasets are useful for the design of landscape-restoration scenarios. They are offered for download individually below and will be offered as single downloadable package in early 2020. These layers (plus more) can also be viewed without downloading them on the Webmap tab.

LANDSCAPE RESTORATION OPPORTUNITIES ANALYSIS
Coming Soon

The landscape restoration opportunities analysis is a package of layers that identifies spatially-explicit restoration opportunities in the Delta to support multiple desired ecological functions. These analyses are informed by past and present land cover, elevation, sea-level rise projections, and other data sets. They will be available for download in late 2019.

MODERN HABITATS
Coming Soon

The modern habitats map layer is a compilation of several spatial datasets detailing Delta vegetation and land use, with each vegetation type crosswalked to the historical habitat types. This layer is a version of the Modern Habitat Type map published in the report A Delta Transformed: Ecological Functions, Spatial Metrics, and Landscape Change in the Sacramento-San Joaquin Delta (SFEI 2014).

HISTORICAL HABITATS

The historical habitats map layer shows the habitat types in the Delta circa the year 1800. It was developed from hundreds of historical maps, photographs, and texts by the San Francisco Estuary Institute as part of the “Sacramento-San Joaquin Delta Historical Ecology Investigation.” The dataset classifies the historical Delta into 17 habitat types, the majority of which are based on modern classification systems.

TIDALLY-REFERENCED ELEVATION
Coming Soon

Elevation is a critical driver of what restoration actions might be appropriate in a given area. Particularly important is a site’s elevation relative to the tides: whether an area is situated within, above, or below the tidal zone (and by how much) influences what types of natural communities can be supported and how vulnerable the area is to flooding. The tidally-referenced elevation layer combines current topographic and bathymetric datasets with local tidal datums to quantify surface elevations relative to tidal heights.

ABOUT

The Delta Landscape Scenario Planning Tool webmap offers users a way view a variety of datasets that are useful for developing restoration scenarios. It is available at http://deltaplanningmap.sfei.org/.

Unlike the desktop Delta Landscape Scenario Planning Tool itself, the webmap is only for viewing data. For actual design, analysis, and evaluation of restoration scenarios, download the tool (here). Many of the layers shown on the webmap can be downloaded from the Resources page, or click the “About this data” tab on a dataset in the webmap.

USING THE WEBMAP

To operate the webmap, press the “Add Data” button below the search box, which will open a data catalog of folders in a pop-up window. The layers are broadly organized around different habitat types. Each habitat type folder will contain layers showing the primary opportunities for restoring the habitat type, as well as a variety of related layers. The folder “Supporting Resources” contains additional general reference layers related to habitat, hydrology, elevation and sea level rise, ownership, jurisdiction, agriculture and infrastructure. These layers provide additional information that is relevant to the development of restoration scenarios.

Clicking on a data layer will generate a description of the dataset, its source, a download link, a preview of the layer. To add this dataset to the main webmap, click the blue “Add to map” button in the right-hand corner of the pop-up window. On the left hand side, layers will be populated as they are added. Click the box to the left of a layer title to toggle the layer on and off. The small arrow to the right of the title shows or hides the legend for that layer. Hovering over a layer will allow you to click and drag layers above or below each other to reorder them. The “Zoom to Extent” button directs the user to the location of the dataset on the webmap. The "About This Data" tab reopens that data information. The “Remove” button allows you to clear the layer from the left-hand panel. The opacity slider enables options for transparency. Click the “About” button for discussion of sharing created maps and data rights.

This project is a tool for planning scenarios of landscape-scale restoration of the Delta. The tool is designed to inform ongoing and future restoration planning efforts in the Delta. In particular, this tool will help inform implementation of restoration objectives as described in the Delta Plan, as well as the ongoing Ecosystem Amendment to Chapter 4.


The need for a scenario planning tool has been discussed by many stakeholders in the Delta. Currently, there is no existing tool to create, evaluate or compare across scenarios or evaluate how scenarios interact or cumulatively add up to at a larger scale. Further, there is no standardized tool that allows parties to accurately calculate desired metrics related to support for ecological functions or other ecosystem services, during project planning or as projects develop over time. This tool will help fill some of these gaps.
