Summary: 2018503 Roadway Plans - Part 3 of 4

This document is a detailed set of roadway construction plans prepared by Propel Engineering, LLC for the Palm Beach County Engineering and Public Works Department in Florida. The project involves the Lyons Road improvement from the L-30 Canal to Boynton Beach Boulevard and includes comprehensive drainage structures, box culvert extensions, and cross-sectional details for the roadway construction. The plans were prepared under Project Number 216, with Professional Engineer Majharul Alam serving as the responsible PE, and were digitally signed and sealed on March 9, 2026. The document contains multiple sheets detailing roadway drainage structures, including existing and proposed drainage elements such as RCP (reinforced concrete pipe), PVC piping, curb inlets, yard drains, and utility conflicts involving water mains, force mains, ITS conduits, and service lines from FPL, AT&T, and Comcast.

The construction plans specify horizontal and vertical scales of 1" = 20' and 1" = 10' respectively and include cross-section details at multiple stations throughout the project corridor, identifying existing and proposed utilities, ground elevations, roadway dimensions, and drainage accommodations. The plans document numerous modifications to existing drainage infrastructure, including inlet relocations to avoid utility conflicts, the extension of a 10' x 6' box culvert by 38 linear feet, and adjustments to 6-inch polyethylene gas main pipes to maintain minimum 3-foot cover requirements. Canal cross-sections show typical slopes of 1:1.5 and 1:20 with rip-rap protection, and the document references multiple technical sheets and details for coordination between the various infrastructure systems throughout the approximately 70-station project length.
