Stormwater Retention Credit Trading and In-Lieu Fee Analyses

This page contains analyses on the Stormwater Retention Credit (SRC) trading program and in-lieu fee, which provide compliance options for sites that face retention requirements. The first spreadsheet explains DDOE’s calculation of the in-lieu fee and contains estimates of SRC demand and supply, price to recover the costs for installing projects to generate SRCs, and financial returns from participating in the SRC and stormwater fee discount programs. The other spreadsheet contains a calculator that estimates the financial return from installing a green infrastructure practice to participate in DDOE programs. DDOE will post additional analyses as they become available.
