Catalina Boulevard Roadway Elevation

The proposed roadway improvements include the elevation of the roadway profile of Catalina Boulevard from Yorkshire Drive to Jollett Court a minimum of 3 feet above the published Base Flood (100-year) Elevation (27 ft, NAVD). The proposed improvements will also include guardrails, curb and gutter, curb inlets, and storm pipes. Given the limited right-of-way, it is envisioned that water quality treatment will be accomplished by a combined proposed storm sewer / exfiltration system. The storm pipes will capture and convey runoff to the existing 24-inch RCP cross-culvert, which will be removed and replaced with an upgraded RCP equalizer culvert. Lastly, any proposed encroachments caused by this project will be offset by creating a compensating storage area within city-owned property adjacent to the impacted water body
