The new development, located in Santa Fe Springs, CA, will consist of a tilt-up industrial warehouse building, on grade, with an approximate building footprint of 150,500 SF. The gas vapor mitigation system shall be designed in accordance with a site specific Phase II Environmental Site Assessment report, and in accordance with the Vapor Intrusion Mitigation Advisory published by the C.A. EPA Department of Toxic Substances Control (DTSC) dated October 2011 (Cal/EPA 2011a, 2011b).
Terra-Petra has been performing continuous inspections in San Diego at the Witt Mission Valley Apartments project since early this year. Terra-Petra observed the installation of a VI-20 geo-membrane and Liquid Boot Vapor Barrier application with smoke and thickness testing most recently.
Terra-Petra is one of the foremost experts on Vapor Intrusion consulting, inspecting, testing, monitoring and mitigation design in Southern California. We are conversant with the many laws, codes and regulations at the city, state, county and national level. We understand the testing, design, monitoring and reporting procedures for many different regulatory agencies.

In early January, Terra-Petra performed a soil gas investigation (SGI) in Los Angeles, CA, in accordance with LADBS guidelines (Information Bulletin Ref. No. 91.7104.1, P/BC 2002-101) under Terra-Petra’s LADBS Methane Testing Lab License #10224, for a major property developer.
We are pleased to continue the partnership to provide mitigation design and consulting services. The project consists of the construction of a new slab on grade warehouse building with a building footprint of approximately 169,253 SF.
There are as many as six (6) oil wells on this property, three of which may fall under the footprint of the new building. The scope of work includes methane mitigation plan design (passive system) and permitting, methane gas detection system design (active system) and permitting, and construction administration support.
Terra-Petra’s VP/General Manager, Justin Conaway, and his wife Robin represented Terra-Petra at artworxLA’s inaugural Virtual Wine Tasting Mixer on March 17, 2021. Despite physical distancing, the attendees were happy to know that we can all still connect by sharing a delicious glass of wine while learning about the wine-making process and show support for the artworxLA’s programming.
artworxLA Board Member Grant and his wife Shaya Kirkpatrick graciously hosted this event by donating wines from their boutique vineyard, William Robert Estate Wines, located in Paso Robles, CA. Justin and Robin are now getting ready for their next road trip to Paso Robles thanks to the recommendations from Shaya and Grant Kirkpatrick!
artworxLA’s next virtual event, Gala 29 will take place May 8th- 14th.
Many thanks to Meghan Beckmann of KAA Design for the invitation.
Terra-Petra is investigating historic water intrusion issues at the site. We are performing an A/E study to include the review of window systems, of roofing parapet cap/roofing materials, and destructive testing of the exterior building envelope.
The AE study includes investigation and design development with recommendations for repairs.
Grace Partnership, Inc has on-boarded Terra-Petra to conduct a City of Los Angeles Methane Soil Gas Investigation (SGI) in Los Angeles. The property falls within a Methane Buffer Zone.
Terra-Petra recently completed the site assessment and sampling in accordance with LADBS guidelines under Terra-Petra’s LADBS Methane Testing Lab License #10224.
We are in the process of drafting the Summary of Methane Soil Gas Investigation report and will be delivering it to the client shortly.
Terra-Petra wrapped up a City of Los Angeles Methane Mitigation and Gas Detection System Design for a Level 5 methane site for Welcome Projects of Los Angeles, CA. Terra-Petra provided design consultation for the new ground up single-family Accessory Dwelling Unit (ADU) as well as the addition to the existing home.
We are open and operating.
Many of you have heard the announcements from the Governor and local LA county officials regarding “safer at home” mandates. Based on a review of the orders and applicable exemptions, Terra-Petra is continuing to operate under the Essential Business category.
As we continue to operate, however, we will comply with all pertinent requirements of the orders.
As an engineering firm that works with contractors and other engineers on critical projects, we also fall into the “Necessary Services” category, along with the various other disciplines of engineering.
The majority of the work that we take on includes municipality, public works, affordable housing, and critical transportation projects.
Our waterproofing division also falls into this category, as our team is in a position to keep properties safe by resolving issues that could ultimately lead to health concerns such as mold and mildew spores, along with other health irritants impacting a person’s well-being.
We will continue to work diligently with our clients to provide safe working conditions on-site for all of our people. We also want to stress the importance of all of our people practicing proper safeguards that have been published, such as washing hands frequently, keep hands away from the face, using hand sanitizer as frequently as possible, and practicing proper “social distancing” while on-site with other people, if required to attend any meetings (on or off-site).
Please be safe, and feel free to report any concerning issues to management with respect to job site conditions, practices, activities, or anything that you feel is not conforming to health guidelines during these challenging times. Contact us if you should have questions or a need at hand.

In 1996, a cross-section of stakeholders came together in Pittsburgh for the very first federally co-sponsored National Brownfields Training Conference. Terra-Petra’s environmental project team took part as an exhibitor at this 18th annual event, December 10-13, 2019, at the Los Angeles Convention Center.
Cosponsored by the U.S. Environmental Protection Agency (EPA) and the International City/County Management Association (ICMA), the National Brownfields Training Conference is the largest gathering of stakeholders focused on cleaning up and reusing formerly utilized commercial and industrial properties.
The heart of Brownfields 2019 is a dynamic educational program of speakers, discussions, mobile workshops, films and other learning formats that are calibrated to provide case study examples, program updates, and useful strategies for meeting brownfield challenges head-on.
Featuring dozens of educational sessions and mobile workshops including many showcasing the City of Angels and the redevelopment in the surrounding region, the exceptional training offered by the conference has something for both beginners and seasoned professionals.
The conference is also a premier stop for the private sector with a vibrant exhibit hall and other transactional activities that are catered towards companies doing the business of brownfields cleanup and redevelopment. The exhibit hall featured federal agencies, engineering firms, and environmental cleanup companies (i.e. Terra-Petra), as well as legal and financial expertise, nonprofits, and other types of organizations.
