Soil Gas Investigation Los Angeles, CA

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.

Landfill Monitoring And Reporting – Penrose Landfill

Terra-Petra has provided ongoing regulatory monitoring and reporting of the Penrose Landfill, in Sun Valley, since 2002. The scope of our activities has included monthly and quarterly monitoring and reporting of perimeter monitoring probes in compliance with South Coast Air Quality Management District Rule 1150.1 and CalRecycle’s Title 27. The regulations require former landfill sites (such as this) to manage fugitive methane gas emissions offsite to levels below 5,000 ppmv.

This work has included routine gathering and evaluation of field data and the preparation and submittal of a report summarizing all monitoring readings as well as laboratory analyses of landfill gas grab samples.

We are also obligated to conduct annual ambient air sampling (weather station and integrated air sampler) and reporting from surface gas emissions into the atmosphere. All monitoring work is carried out under the direction of our Senior Project Scientist and reviewed and stamped by our Registered Civil Engineering crew.

DMBI Methane Barrier Inspection – Downey, CA

Terra-Petra performed DMBI inspections in Downey, CA for an LA County Construction Company. The inspector was on site to visually witness a slab repair (application of spray) on the 1st day and a smoke test (field testing) on the 2nd.

Terra-Petra has the largest staff of Deputy Methane Barrier Inspectors in the industry with thirteen (13) inspectors and is highly qualified to perform this oversight.

Methane Mitigation Services – Harbor City, CA

Terra-Petra is currently working with a Victorville design team to provide  Soil Gas Investigation (SGI), methane mitigation design, inspection, and consulting services for a retail development located in Harbor City, CA. The project will consist of a new 3-story cannabis facility (occupied by a dispensary, cultivation rooms, manufacturing facility and distribution ) constructed out of steel frame, with insulated metal panel exterior and interior walls, and an open air parking garage below the structure. The total building footprint is approximately 4,712 SF and total site square footage is 41,894.20 SF.

Terra-Petra will be consulting on all mitigation matters relative to the site, including methane testing, laboratory testing, methane mitigation system design, construction administration support, and DMBI inspections to be in compliance with City of Los Angeles Department of Building and Safety (LADBS) codes.

Methane Mitigation Design – Hub on Campus LA Figueroa

Terra-Petra is currently working with AMP Development to provide methane mitigation design and consulting services for the proposed new Hub on Campus LA Figueroa, located in Los Angeles, CA.

The project will consist of the construction of a new 7-story commercial residential mixed-use development with 5,128 SF of commercial space and 157 residential dwelling units with a single level subterranean basement. The total building footprint is approximately 41,600 SF.

The scope of work includes methane mitigation design and permitting, and construction administration support (material submittal review, field sketches, Request for Information [RFI’s], and attending any specialized construction coordination conferences).

Methane Soil Gas Investigation – Enlightenment Plaza

Terra-Petra completed a methane soil gas investigation on behalf of Killefer Flammang Architects at Enlightenment Plaza, in Los Angeles, CA. The new multi-phase development will include the construction of 5 new slab on grade apartment buildings.

The overall site is approximately 90,984.2 SF. LADBS required a site investigation as the property falls in a Methane Buffer Zone. Terra-Petra completed the LADBS required MSGI under Terra-Petra’s LADBS Methane Testing Lab License #10224.

Methane Mitigation Design – Torat Hiyam

Level II Methane Mitigation Design

Terra-Petra has just closed  with Torat Hiyam to provide methane mitigation design for their new project in Los Angeles, CA.

The new construction will consist of a 5 story school building, with a basketball court and a library.

The scope of work will include a Level II methane mitigation design plan with permitting to be approved by LADBS Mechanical Department Plan Check.

Methane Soil Gas Investigation In Los Angeles

Terra-Petra has submitted a bid to Data Specialties to conduct a methane soil gas investigation on a LADBS Methane Buffer Zone Property on in Los Angeles, CA.  The proposed project will consist of an electrical upgrade, with no new building construction.
