PENCO was selected by Walt Disney Imagineering to provide civil engineering design and survey services for various projects for the California Adventure Resort.

PENCO provided civil engineering and survey services for this new 1,000-room hotel, including on-site grading, drainage, and dry and wet utility design.

This project required very close coordination with the adjacent California Resort project and off-site infrastructure improvements for the widening of West Street.

PENCO upgraded traffic and pedestrian flow between the new and existing hotels and enclosed parking beneath Downtown Disney.

This project included design of a 100-year on-site storm drain detention with underground pumping system.

Detention also included a 30-foot by 60-foot concrete tank, with three submerged pumps. One year after construction was completed, the project experienced a 100-year storm event. All pumps and basin performed, as designed, without any complications. The hotel courtyard area was utilized to relieve the 100-year storm drain.

Utility design challenges included design for pipe cover for heavy truck loads in the loading areas.

All grading plans were designed at a 10-foot scale to clearly eliminate construction conflicts for wet and dry utilities, including special landscape paving systems.

Plans were processed through the City of Anaheim for this fast-track project.
