San Diego As-Needed WIFIA Stormwater Design Projects

Harris is providing as-needed stormwater design services to the City of San Diego using funding through the Water Infrastructure Finance and Innovation Act (WIFIA). Some of our notable projects under this contract include:

Mission Hills NE Storm Drain Replacements Project

This project consists of the repair or replacement of approximately 2,000 linear feet of 18- to 24-inch diameter reinforced concrete pipe (RCP) storm drain, including other design elements such as concrete catch basins with curb inlets, concrete energy dissipators, riprap, and concrete cut-offs walls for steep terrain installations. The scope also includes abandonment of 449 linear feet of 12-, 15-, 18-, and 24-inch corrugated metal pipe (CMP) and corrugated plastic pipe (CPP), pavement restoration improvements, and ADA-compliant curb ramps. The work is spread across seven locations in the Mission Hills and Hillcrest neighborhoods of San Diego.

Harris is preparing plans, specifications and engineer’s opinion of probable costs for the proposed improvements, which includes civil design, hydrology and hydraulics studies, surface and subsurface investigation, structural engineering, geotechnical engineering, California Environmental Quality Act (CEQA) and regulatory permitting compliance, revegetation planning and design, and support during the bid and construction phases. Construction is expected to start in early 2027.

Campus Point Drive Storm Drain Replacements Project

This project consists of the replacement of approximately 350 linear feet of existing 18-inch diameter CMP with 24-inch diameter RCP storm drain, including other design elements such as concrete catch basins with curb inlets, concrete energy dissipators, riprap, and concrete cut-offs walls for steep terrain installations. The work is in the University City neighborhood of San Diego.

Harris is preparing plans, specifications and engineer’s opinion of probable costs for the proposed improvements, which includes civil design, hydrology and hydraulics studies, surface and subsurface investigation, structural engineering, geotechnical engineering, CEQA and regulatory permitting compliance, revegetation planning and design, and support during the bid and construction phases. Construction is expected to start in the fall of 2026.
