Project Summary

Nasland Engineering has been providing civil engineering services to UCSD’s Scripps Institution of Oceanography (SIO) over the past decade. Services included implementation of stormwater infrastructure projects in accordance with their master plan to improve overall campus drainage, reduce erosion, and reduce flooding.

SIO Stormwater Master Plan
Nasland provided civil engineering services for eight stormwater management projects for the UCSD GRANT program. The projects included: Director’s Office Storm Drain and Media Filters; Pier Area Media Filters and Drainage Upgrades; Hubbs Hall Low Flow Diversion; Seaside Forum; Storm Drain and Media Filter; and Wash Racks. The purpose of the GRANT program was to implement Best Management Practices (BMP’s) that included: pollution prevention measures; treatment controls; dry weather flow diversion; site controls to eliminate non-storm water discharges; reduce the loading of pollutants of concern; improve the water quality; and protect valuable ocean resources.

SIO Seawater Separation Return Pipeline
UCSD retained Nasland to provide design and construction support for the SIO Seawater Separation Return Pipeline project. The design for the new dedicated saltwater pipeline system was unusually difficult because of numerous and abrupt changes in grades, an extensive network of existing underground utilities, narrow roadways that could not be shut down due to operational and fire protection requirements, sensitive habitat and other environmental concerns. Due to these constraints, trenchless techniques were specified for most of the pipeline construction. Horizontal Directional Drilling (HDD) was used for new pipes and a Cured-in-Place Pipe Liner was installed in existing pipes that were reutilized in the system.

SIO Hubbs Hall Storm Drain Improvements
Nasland designed a horizontal directional drilled storm drain system to bypass the City of San Diego’s over capacity system. The project also involved changing out the storm water media on four storm water treatment basins.
