Stormwater Tools Modules
The Stormwater Tools web application is perfectly suited for multi-jurisdictional collaboration while facilitating inter-operability with other data systems.
The application includes the following modules:
Inventory Module
The Inventory Module is the foundation of the Stormwater Tools platform. It is used to develop and maintain a complete record of structural BMPs, along with their attributes, performance parameters, and related inspection and maintenance logs. System administrators are able to configure and add BMP types, attributes, benchmarks, thresholds, and weighting.
Trash Module
This module is a calculation engine that brings together asset information with other GIS resources to provide real-time quantifications regarding progress. Staff are able to manage jurisdictional land use layers for both priority and alternate land uses, assign attributes to inventoried BMPs, perform On-land Visual Trash Assessments (OVTAs), and view current progress reports all within the system. Progress can be viewed in multiple ways, including area-based (PLU acres), load-based (gallons per year), and OVTAs (acreage of full capture equivalent).
Modeling Module
This module quantifies stormwater capture and pollutant load reduction directly from the BMP inventory and development sites. Calculations occur in the modeling engine which maintains a network of catchments, BMPs, and flow paths to recalculate results in real-time when users update the asset inventory. The calculation approach accounts for the cumulative benefit of nested stormwater treatment facilities. It enables web-based modeling by automatically calculating the subset of the watershed affected by an asset inventory update. Module users can easily view calculated reductions for multiple regulated stormwater pollutants including bacteria, metals, TSS, and nutrients, and they can quantify urban runoff captured during dry and wet weather.
