The Storm Water Evaluation Tool (SWEET)
RPS led a team to help the City of Houston revolutionize its approach to storm water management, which significantly impacts public safety, infrastructure, and construction in the city where more than 50 inches of rain falls annually. The Storm Water Evaluation Enhancement Tool (SWEET) combines Geographic Information System (GIS) tools, with the City’s information databases, to produce an objectively ranked list and map showing where drainage and flood control measures are most needed. Using databases that are regularly updated, SWEET provides a dynamic and current tool that has since been expanded to include 33 million feet of open drainage systems.

Challenge
RPS was challenged with developing a GIS tool using data from multiple sources that is constantly being updated. The City needed a transparent, defensible process to determine the worst needs in the City.
Solution
RPS developed SWEET that incorporates new data as often as the City would like to update the model. City Staff can legitimately point to specific projects as the most critical as defined by criteria agreed to by numerous stakeholders.
