BAS Assisting Municipalities in the Development
GIS Brownfields Inventory Databases
BAS, in partnership with Project Navigator Ltd. (PNL), has been selected by several southern California municipalities to develop GIS-facilitated land portfolio screening tools in support of urban redevelopment programs.
The City of San Bernardino Economic Development Agency selected the BAS/PNL Team to create a GIS-compatible Brownfields Inventory Database and site ranking tool for the 7,600-acre San Bernardino Greater Downtown Revitalization Area (SBGDRA).
The inventory is the first step in the ultimate characterization and remediation of sites within the SBGDRA. The inventory will be utilized by the client to identify those properties whose redevelopment represents the highest potential benefit to the City. As property assessment and remediation efforts progress, the inventory will become a critical decision-making tool in the Agency’s continuing redevelopment efforts throughout the SBDGRA.
In another project, the City of Lynnwood selected the BAS/PNL Team to develop a database of properties in the 140-acre Long Beach Specific Plan Area, and to establish criteria to prioritize sites for further environmental investigation. The goal is to create a tool that the City can use to develop the most logical, cost-effective approach to cleaning up and restoring abandoned and blighted properties in the revitalization area.
BAS has more than 24 years conducting multiple-parcel site assessment, environmental screening, and remediation support for large infrastructure improvement projects.
BAS Supports County of Orange in
Emergency Repair of Freeway Complex Fire Damage
The Freeway Complex fire ravaged portions of Orange, Riverside, and Los Angeles counties, in mid-November 2008. The fire started in the city of Corona and quickly spread west into the hillsides of Yorba Linda and Brea, where it damaged facilities and equipment at OC Waste & Recycling’s Olinda Alpha Landfill.
Significant damage was done to the landfill gas extraction and control system at the Olinda Alpha Landfill, rendering it inoperable. Extraction wells, laterals, isolation and valves on the front face and southeast slopes of the landfill were destroyed or damaged.
OC Waste & Recycling selected BAS to provide emergency repairs to the system in late 2008. BAS currently provides on-call landfill gas services to landfills in OC Waste & Recycling’s North Region, and was able to quickly mobilize resources of its construction contracting subsidiary BAS Construction LP to implement the repairs.
Phase I repairs, completed in early February, restored main header lines and lines to the site gas-to-energy plant and flare station. Phase II involved repairing system components in the south and east portions of Olinda and Olinda Alpha Canyons. This includes trenching, pipe fusing and installation, and installation of wellheads, laterals, and connections to the main header system.
BAS Landfill Redevelopment Planning
Practice Continues to Grow
Redevelopment of historic landfills for commercial, residential, and recreational uses has gained increasing popularity in recent years. BAS has applied its broad experience in landfill closure design and landfill gas management to support three significant projects in Southern California.
BAS is a subconsultant to Tetra Tech on a project to construct a mixed-use commercial and residential development on the former Cal Compact Landfill in Carson, California. The project consists of construction of commercial and residential development over the 157-acre former Class II Landfill. Over 2.4 million square feet of pile-supported structural concrete slabs will support the buildings at the site. BAS is responsible for the design of landfill gas management measures to protect the public from methane gas migration, and for the design and permitting of the final cap system for the site.
In another project, BAS is supporting the Anaheim Redevelopment Agency and a private developer in the construction of a commercial development at the site of three historic municipal landfills. The proposed project will involve construction of 258,000 square feet of retail, commercial, and restaurant buildings. BAS responsibilities include evaluation and design of a landfill cap, landfill gas control measures, and membrane systems for the protection of proposed development features.
In a third project, BAS is providing planning and engineering services to the City of Long Beach for the development of municipal park improvements on portions of the former Davenport Landfill. BAS will be responsible for preparation of waste characterization studies, a Final Post Closure Land Use Proposal and associated plans, construction level plans and specifications for site closure, and record drawings. In addition, BAS will be providing engineering support for park improvements to be constructed at the site.
BAS has been a leader in the development of innovative landfill closure approaches since 1984, when it developed the first U.S EPA-approved closure plan for a Class I Landfill facility in the western United States.
