The document provides guidelines for writing and reviewing proffer agreements between developers and counties. It recommends identifying project impacts and applicable county policies, coordinating review among teams early in the submission process, using clear and enforceable language, and incorporating flexibility. It also outlines new requirements for proffer compliance narratives to be submitted with building plans, bond reductions, and other requests in Fairfax County effective June 2017. Training on the new process will be provided in May 2017.
