methane mitigation

Methane Mitigation Design has been a specialty of Terra-Petra for over 25 years.  We are a goto resource for methane mitigation and methane soil gas mitigation design in Los Angeles and throughout Southern California. With a Civil Engineer, Registered Environmental Assessor, Registered Geologist and Certified Engineering Geologist on staff, we design these systems all day every day.

We are very conversant with the code requirements for the City of Los Angeles, the County of Los Angeles Environmental Programs Division, the Orange County Fire Authority and the Fire Departments of Los Angeles, Huntington Beach and El Segundo. We routinely design both passive and active systems. Where it is deemed appropriate, Terra-Petra can design mechanical vapor extraction systems and electronic gas detection and alarm systems – employing the latest technologies.

Terra-Petra takes pride in shepherding our plans through the plan check process in order to provide each of our clients with agency approved plans. Since each project has it’s particular uniqueness, it may be prudent to submit a Variance/Modification for an alternate Mitigation Design–one that often affords the developer a cost savings. It is important to note that Terra-Petra has roughly an 85% success rate on our Variance/Modification submittals. Click on Featured Projects for a sample of designs completed by Terra-Petra.
