Site Investigation and Remediation of Commercial/Industrial Property in Albany, Georgia

2026-04-02T15:50:27-06:00October 20th, 2009|Tags: |

Due diligence performed by Geosyntec for a former lease on behalf of the property owner indicated several potential Recognized Environmental Conditions (RECs) on site that warranted further evaluation. Geosyntec completed due diligence activities with the goal of managing the site assessment and subsequent remediation of chlorinated pesticides within the guidance of the Georgia Hazardous Sites Response Act (HSRA) and Georgia Hazardous Site Inventory (HSI). Once a site is listed on the HSI, significant costs can be incurred for regulation-required delineation of contaminants of concern to background concentrations (non-detect in the case of pesticides). Geosyntec successfully managed the project to avoid a HSI listing.

Vegetated Roof Assessment Using Satellite Imagery for City of Chicago

2026-04-02T15:50:52-06:00October 20th, 2009|

The City of Chicago has been a leader in implementing green practices in an urban environment and encouraging both the public and private sector to apply such practices through the development of various City programs and policies. An example of this leadership is the implementation of the City's Department of Housing and Economic Development's (DHED) Sustainable Development Policy which requires buildings that receive financial assistance or are part of a planned development to install a vegetated roof. DHED retained Geosyntec to assist the Department, through the use of satellite imagery, in identifying the number, size and relative health of the vegetated roofs within the City of Chicago boundary and to link the identified roofs back to specific City programs and policies, where known.

Stormwater Low Impact Development Design for Schmul Park on Staten Island

2026-04-02T15:50:52-06:00October 20th, 2009|Tags: |

The New York City Department of Parks and Recreation (DPR) identified the 2.5-acre Schmul Park on Staten Island for redevelopment into a state-of- the-art neighborhood recreational park, part of the overall redevelopment of the Fresh Kills Landfill as a 21st Century recreational resource for the citizens of New York. DPR, through their lead Master Planning firm, Field Operations, Inc., retained Geosyntec to design Schmul Park with an eye towards innovative, forward-thinking low impact development (LID) designs to minimize stormwater impacts to the surrounding environment. The plan is to convert the current aging asphalt-dominated park into a new playground including a spray park, porous handball and basketball courts, porous walkways, a rain garden, and new open green spaces.

Stabilization of Active Landslide

2026-04-02T15:50:53-06:00October 20th, 2009|Tags: , , |

A large landslide occurred at a site under development by a third party in Western Pennsylvania, impacting an adjacent state highway and rail line. After emergency actions were implemented to reopen the highway and rail line, stabilization of the site was to occur under consent order between the state and the third party. With the goal of stabilizing the site as quickly and efficiently as possible, the prospective purchaser assumed the responsibility of responding to the consent order and retained Geosyntec to develop and evaluate options for stabilizing the site.

Geotechnical and Seismic Engineering Services for Phased Commercial Development Adjacent to San Francisco Bay

2026-06-16T14:30:27-06:00October 20th, 2009|Tags: |

The site is an approximately 23-acre, undeveloped parcel in an area of office buildings, hotels, and the Brisbane Marina. Subsurface conditions include fill and refuse material, thick compressible clay deposits, and underlying alluvium and bedrock. The overall site development plan consists of the construction of five, three- to four-story buildings, a multilevel above-ground parking garage, surface parking, and miscellaneous site improvements, including pavements, landscaping, and utilities.

VA Medical Center Campus New Construction Geotechnical Investigation and Seismic Hazard Analysis

2026-06-16T14:30:14-06:00October 20th, 2009|Tags: |

The Department of Veterans Affairs (VA) is proposing to construct three new buildings and perform chiller system upgrades at the existing medical center campus in Long Beach, California. As part of the pre-design process, Geosyntec was selected to perform a geotechnical investigation and seismic study. The geotechnical investigation was performed to characterize the subsurface at the site, perform engineering analyses, and provide geotechnical engineering recommendations related to design and construction of the proposed facilities. The investigation included a seismic study performed to evaluate the seismic hazard at the site and develop site-specific ground motion parameters in accordance with the VA Seismic Design Requirements, H-18-8.

Proposed Substation Geotechnical Investigation

2026-06-16T14:30:26-06:00October 20th, 2009|Tags: |

The San Diego Gas & Electric Company (SDG&E) is proposing to construct a new 138-kV substation adjacent to an existing 138-kV substation and replace the existing 138-kV substation with a new 230-kV substation in San Juan Capistrano, California. Geosyntec was contacted by SDG&E to perform a geotechnical investigation as part of the as-needed geotechnical contract between Geosyntec and SDG&E. The geotechnical investigation was performed to characterize the subsurface at the site, perform engineering analyses, and provide geotechnical engineering recommendations related to earthwork, grading, retaining wall, and foundation design for the proposed substation. The project site is underlain by the landslide-prone Capistrano Formation and the potential for landslides was evaluated as part of the geotechnical and geologic hazards investigation. The proposed new graded pad for the new 138kV substation involved cuts and fills on the order of 25 feet with a new retaining wall planned along the new access road on the site and within the proposed new substations.

Field-Scale Verification of Engineering Properties for Sluiced Fly Ash

2026-04-06T13:04:26-06:00October 20th, 2009|Tags: |

American Electrical Power (AEP) is developing a 348-acre residual waste landfill (RWL) located over portions of an inactive fly ash reservoir (FAR) and an area of historic mine spoil deposits near Brilliant, Ohio. Geosyntec's design required the sequential development of the RWL with a preloading period. To develop a better understanding of the required preloading period, Geosyntec designed and implemented a monitored preload fill (MPF) test program to evaluate the specific in-place compression and drainage characteristics of the fly ash in the FAR.

Air Quality Permit Consulting and Development of a Compliance Tracking Tool

2026-04-06T09:21:22-06:00October 19th, 2009|Tags: |

Geosyntec was retained by a confidential University client in the Philadelphia area to provide air quality consulting assistance to modify the University's air quality permit and develop a compliance tracking tool for the facility.

Air Permitting for Landfill Gas Beneficial Reuse Projects

2026-04-06T13:21:34-06:00October 19th, 2009|Tags: |

DeKalb County (DeKalb) wanted to expand its ability to use excess landfill gas (LFG) at its Seminole Road Municipal Solid Waste Landfill for beneficial use. DeKalb desired to: (i) construct a facility that would convert LFG to renewable natural gas (RNG); (ii) add a third engine to an existing Green Energy Facility (GEF) producing electric power through landfill gas-fired reciprocating internal combustion engines; and (iii) install a second flare to increase the capacity to burn LFG when both the GEF and the LFG to RNG were down. Because this facility is located in Atlanta's Nonattainment Area (NA) for ozone emissions, it is considered a New Source Review (NSR) NA major source. Therefore, it may only increase its nitrogen oxides (NOx) and volatile organic compounds (VOCs) emissions by 25 tons every five calendar years. Otherwise, costly and time consuming NSR NA permitting would be required. The site also is a Prevention of Significant Deterioration (PSD) major source for carbon monoxide (CO), and NSR PSD permitting would be required if CO emissions increased by more than 100 tons per year.
