Once you have created a site, you can review a detailed profile with data about your site’s conditions and location. This profile is generated using available data sets and should be supplemented with observations collected from site visits, community engagement, feasibility studies, and other means.
Accessing the site profile
To access the site profile:
Create a site, or click on an existing site
Your site profile will open in the righthand panel
To toggle the site profile between a minimized or expanded state click the icon with two arrows at the top right of the panel.
Understanding the site profile
The site profile consists of three tabs:
Benefits: This tab shows an overview of the benefits of your design once you have added remedies to your site. For more details on benefits and costs, click here.
Conditions: This tab shows the site's current conditions based on available data sets.
Details: This tab shows information about the site's area, land use type, and location.
Within the Conditions tab, you can see:
Opportunities: This section includes a ranked list of opportunities to make improvements on your site. If an opportunity is ranked high, it means there is an opportunity to make improvements on the site relative to the rest of LA County.
Land: This section includes a breakdown of land cover on your site.
Water: This section provides an overview of your site's potential for collecting stormwater, including the rainfall on or near your site, as well as any underlying groundwater basin and the suitability of underlying soils for infiltration.
Most opportunities are calculated by taking an average of all of the values on the site. For example, the Cooling opportunity is evaluated by looking at the average heatwave temperature on the site. One exception is the Water Supply opportunity. In this case, the water supply potential is identified assuming that a site design would find a single nearby location to divert water from to bring onto the site. Based on this assumption, we find the highest runoff value within 200 feet of the site. Locations with a runoff contribution area greater than 10,000 acres are assumed to be fed by major natural streams and are excluded from consideration.
Opportunities are ranked from Very Low to Very High based on how the value for the site compares to the distribution for the rest of LA County. You can pin an opportunity by clicking the star icon. Pinned opportunities will appear at the top of the Benefits tab for quicker reference.
Within the Details tab, you can see:
Site: This section includes information about your site's size, land use type, land ownership, and geographic coordinates.
Policy Details: This section includes information about the locations CalEnviroScreen score, CalEnviroScreen Disadvantaged Community status, and nearby existing infrastructure projects.
Location: This section includes information about the site's jurisdictional, natural, and historical boundaries.
For more information on any of the data points in the profile, hover over the data card and click the guidebook icon.
Visualizing site data on the map
The data underlying every card in the site profile can be visualized on the map. To visualize the data, simply click on the card. When you do so, the underlying layers will appear on the map, including a legend at the bottom left corner of the screen.
When you click on a benefit or opportunity, a layer pack will turn on, including multiple layers that are related to the benefit. In the example above of Cooling, several layers are shown in the legend, including Heatwave Temperature, Cooling Centers, and Tree Canopy. The metric layer shown (in this case, Heatwave Temperature), is used to generate the opportunity metric for the site.
To learn more about any layer, click the guidebook icon in the site profile card or layer legend.
