Parcel Based Stormwater Runoff Calculator for Hamilton County Ohio

Complaints about stream and sewer flooding have been increasing. Many departments need to do accurate stormwater calculations but have lacked affordable and useful software tools. Hydrologists and engineers usually calculate stormwater data for watersheds (i.e., drainage areas); the majority of a local government’s work is based on individual parcels and addresses. Quantifying stormwater in a fair, accurate and economical way was so difficult that these calculations were seldom included in the review of subdivisions or building permits. When such calculations were made, sharing them throughout the enterprise was difficult. CAGIS has developed a runoff calculator that makes the model output useful and accessible for local government.
