The Flood-Prone Urban Area (FPUA) was established by Ordinance No. 4467 and contains many problematic drainage areas caused by flat topography and backwater effects from the Laguna de Santa Rosa. Therefore, any fill placed in the FPUA requires a grading permit in accordance with SCC §11.04.010 and a drainage analysis in accordance with SCC §11.16.040.C.8.
