Pismo Preserve

The Land Conservancy
Pismo Beach, California

Project Summary

In 2014, the Land Conservancy of San Luis Obispo County purchased the 880 acres of land that was slated to be transformed into the Pismo Preserve. Funded through local and state governmental agencies, grants, and generous donations from the community, the Preserve would come to offer locals and visitors the chance to explore a scenic 11-mile multi-access trail system winding through a diverse open space of oak woodlands and chaparral with panoramic views of the Pacific Ocean that had previously been closed to the public.

In addition to the trail system, the project also incorporated construction of a 54-space parking lot with public restroom facilities and an equestrian parking lot, retaining walls featuring native plant species, creation of an ADA accessible trail and bridge, site utility installation, and improvements to Mattie Road.

Geotechnical Services

Prior to construction, Earth Systems prepared a Geotechnical Engineering Report that provided geotechnical recommendations for use in the development of plans and specifications for the ADA accessible trail, parking lot, and construction of the sidewalk, driveway, and parking areas along Mattie Road.

Special Inspections and Materials Testing

Over the course of construction, Earth Systems provided the following:

  • Observation and compaction testing during grading operations
  • Compaction testing during utility trench backfill operations
  • Caisson depth inspection
  • Special inspection of concrete
  • Special inspection of field and shop
  • Special inspection of shear wall nailing
  • Special inspection and structural testing of soldier pile wall construction and structural placement of rebar and concrete
  • Project management and report preparation
