Benefits Toolkit
The Landscape Performance Series Benefits Toolkit is a searchable collection of online tools and calculators to estimate landscape performance.
The tools can be used to estimate specific landscape benefits for completed projects when actual measurements are not available, or they can be used in the design phase to compare projected benefits among various options. Many tools also allow the user to compare life-cycle costs for conventional and sustainable design features.

2009This Excel-based calculator was designed as an awareness tool to give a general idea of what is needed to keep pre- and post-development runoff volume the same. It can be used to compare the increase in runoff volume for development with and without stormwater BMPs. The calculator is designed for California communities, but users from elsewhere can input their own rainfall data to use the calculator. Inputs include: project site area, existing and proposed dominant non-built land use types, and existing and proposed roof and non-roof built area. The user then fills in various worksheets for BMPs used, such as porous pavement, downspout disconnection, and green roofs. Outputs are: pre-project runoff volume, project-related runoff volume increase without BMPs and project-related volume increase with BMPs.
