Clearwater Memorial Causeway Subaqueous Pipeline

Ardurra delivered surveying and engineering design services for the critical replacement of water infrastructure across Clearwater Harbor and the Intracoastal Waterway, successfully completing the design for 2,500 linear feet of replacement force main and 2,700 linear feet of new 20-inch pipeline. The complex marine infrastructure project required specialized surveying techniques and regulatory compliance across multiple waterway jurisdictions.

The team conducted a detailed topographic survey using conventional ground survey methods and sophisticated bathymetry for water bottom mapping. Comprehensive utility documentation included invert elevations, pipe sizing at manholes, storm drains, and accessible structures, while maintaining strict OSHA compliance throughout field operations.

Key Project Highlights:

• Designed 5,200 LF of marine pipeline infrastructure, including 2,500 LF of force main replacement and 2,700 LF of new 20-inch pipeline

• Conducted specialized bathymetric surveying for accurate water bottom mapping across Clearwater Harbor and Intracoastal Waterway

• Performed comprehensive utility documentation, including invert elevations, pipe sizing, and storm drain system mapping

• Established Mean High Water (MHW) line elevation through precise jurisdictional surveying for regulatory compliance

• Completed cross-sectioning analysis of Intracoastal Waterway bottom at 50-foot intervals for design optimization

• Coordinated wetland/surface water delineation with specific purpose jurisdictional survey requirements

• Provided ROW monumentation along the entire route with sketch and legal documentation for permitting

• Located geotechnical test borings supporting foundation design and construction planning

The project provided Clearwater with enhanced water infrastructure capacity while navigating complex marine construction challenges. Detailed surveying and engineering design services ensured regulatory compliance and construction feasibility across sensitive waterway environments.
