← Back to Oceano Drainage Improvement

Overview

The intersections of 13th Street/Hwy 1 and 17th-19th Street/Hwy 1 in Oceano experienced flooding during significant rain events.   Cannon is currently working with the County to design new storm drain improvements to alleviate these drainage issues. Improvements include new inlet structures, culvert pipes, junction structures, LID detention basins, and outlet facilities.

Major considerations include hydrology and hydraulics (i.e. upstream/downstream drainage impacts), topography, property access/acquisition, railroad crossings, utility conflicts, environmental permitting, construction and O&M costs, and implementation schedule.
