Boynton Beach, FL Green Infrastructure Toolkit Results

Basins: This layer shows the three largest runoff basins that flow into the core of parcels within a neighborhood block (contiguous parcels bounded by streets). As such, it is a "flood forensics" tool that seeks to identify how stormwater runoff flowing to a neighborhood may contribute to flooding (i.e. if storm drains are over-loaded, under-sized, and/or clogged). The Basins layer is created only after parcels or neighborhoods with a history of flooding are identified.

City Parcels: This layer shows all the parcels that are owned by the city of Boynton Beach. The City Parcels layer is designed to be searchable through the web map's search bar using either address or place name (e.g. Sara Sims Park). The search function currently works only for the preliminary target neighborhood extent.

Sinks: The Sinks layer shows where water is likely to pool during heavy rainfall events. Sinks represent particularly low-labor and low-cost opportunities for reducing runoff through planting deep-rooted vegetation (incl. trees), mowing less, and/or depaving.

Tree Canopy: The Tree Canopy layer identifies where tree canopy is present within an area of interest. The layer can be used for direct visualization or as an input for various other studies, such as comparing canopy coverage from one neighborhood to another. The Tree Canopy layer can be compared to the Land Surface Temperature (Surface Temp) layer to mitigate heat islands. Or, tree canopy (or lack thereof) can be integrated into green stormwater infrastructure design.

Runoff Channels: This layer shows where runoff is most likely to flow and channelize during heavy rainfall events. Smaller tributaries are shown in very light blue and the channels they flow into are shown in darker blue. Arrows indicating flow direction are also included. Green infrastructure can be most effective when installed in these channels, especially just before channels flow onto paved/impervious surfaces (i.e. "veg the edge"). Only the higher flow channels are shown when the map is zoomed out. In this way the channels are not excessively crowded and still provide usable information at low zoom levels.

Surface Temp: This layer displays remotely estimated land surface temperature. Red areas indicate hotter temperatures whereas blue areas indicate cooler. Any red area can be considered a heat island. This layer is from June 25, 2025 and has a temperature range from 81 to 103 F.
