Roadway Design

Cornerstone Engineering engineers and technicians have a broad range of public works and private development experience, from the design of state highways to rural access roads and dozens of projects in-between.

Water and Sewer Design

Cornerstone Engineering has planned and designed countless miles of water and sewer pipelines. Most of our site development plans include fire line, water and sewer systems. We have designed high-pressure water transmission mains and performed hydraulic transient analysis for water hammer control. Installation methods have included jack and bore, micro tunneling and other trenchless technology methods.

Storm Water Design

We have designed a number of storm water systems that meet current Best Management Practices, and have prepared many Storm Water Pollution Prevention Plans (SWPPP’s). We are very familiar with the storm water regulations and are aware of recent court decisions regarding interpretation of the regulations (Friends of the Bay vs. Caltrans, Port of San Diego, etc.).
