From the ordinance
A water quality impact assessment is required for any proposed development with an RPA, including any buffer area modification or encroachment as provided for in Section 22-100 c.2, of this Part, and in any development in the RMA if (i) the proposed development exceeds 50 acres, or (ii) the proposed development results in more than 60 percent impervious cover on the lot or parcel being developed.
