The SFPUC Green Infrastructure Maintenance Model is an Excel-based planning tool that is used to plan and budget for future green infrastructure maintenance obligations in terms of both labor and dollar costs. The SFPUC has made the model available for sister municipal stormwater agencies to use for planning-level analyses. A recording of a recent presentation about the model and how to get a copy is available here.
