Brownfield’s and Site Redevelopment
Brownfield’s, environmental assessments, cleanup and stigmatized collateral are a business challenge on: “How to allow for a sustainable redevelopment to occur on contaminated property”. NOA’s knowledge and proven experience combines reconstruction with a viable environmental remedy. Through consulting “beyond the chemistry,” NOA provides redevelopment clients with property-specific solutions at the pace required of business, not environmental regulation. Local agency governments or private sector clients desiring to capitalize on Brownfield’s programs as part of their redevelopment strategy can benefit from NOA’s private and public site redevelopment experience, including:

  • Grant Writing, Management, and Reporting
  • Brownfield’s Program Management and Support
  • Community Involvement Plans, Outreach, and Engagement
  • Brownfield’s Inventories/Property Prioritization and Ranking
  • EPA Brownfield’s Property Eligibility Analyses
  • All Appropriate Inquiries and Continuing Obligations Support
  • Quality Assurance Project Plans

Natural Resources, NEPA / CEQA and Wetlands Delineation
A number of industrial, corporate and public agency clients need to close and transfer properties, or update existing resource management plans for those properties. NOA’s geologists and environmental scientists have the expertise and experience to prepare resource management plans to guide clients through the associated regulatory processes. NEPA/CEQA – The requirements established under the National Environmental Policy Act (NEPA), or California Environmental Policy Act (CEQA) can present a formidable obstacle to development projects. Our experience has shown that a carefully considered review of environmental concerns can provide an effective framework for both development and conservation of natural resources. We have assisted clients with natural resource management through the performance of multi-disciplined analyses, planning and design projects.

Wetlands Delineation
NOA also offers a full range of wetland services, ranging from the initial wetland determination to developing a wetland mitigation plan and submitting a permit application to the U.S. Army Corps of Engineers (USACE). In order to achieve project goals, we work closely with our clients and the USACE to determine optimal use of the property, while taking into consideration existing wetlands and proposed mitigation areas.

Regulatory Compliance
NOA has positioned ourselves to be a most cost-effective resource for the preparation of compliance documents such as permit applications, Spill Prevention Control and Countermeasure (SPCC) plans, wastewater discharges, as well as plans for storm water pollution prevention, chemical accident prevention, emergency response and waste management unit closures. Our professional staff of environmental and geotechnical engineers and geologists can assist, evaluate and resolve the regulation and management of hazardous materials required to allow for project development.

Solid Waste Planning and Design
It is inevitable that communities will continue to produce and dispose of unlimited amounts of solid waste. Based on historical records and accumulated knowledge more stringent regulations and increased public scrutiny have increased the difficulty in locating and also in designing new solid waste facilities. NOA offers a full array of consulting services to public agencies and private sector clients involved in solid waste management. Our local expertise and knowledge provides our clients with innovative and cost-effective solutions to meet waste management needs. We can assist clients through all phases of landfill development and landfill design. Additionally, NOA is able to provide geotechnical engineering, geologic, construction quality assurance and construction materials testing services.

Effluent Waste Disposal Design
Our firm has designed and overseen the installation of many septic disposal systems ranging in size from small home units to larger community systems.  Our engineers and geologists are experienced in field investigation and classification for the properly engineered disposal systems for our clients’ needs.  Often developments may occur in areas that may not yet utilize main stream community waste water treatment systems.  In such cases it is important that an experienced and qualified team design a site specific system that will be able to handle the needs of the project at hand. NOA is able to provide such services in a timely and affordable manner.
