How long does a reclamation project take?

Reclamation timelines vary enormously depending on site size, contamination type and extent, regulatory requirements, and end-use goals. Small-scale reclamation projects may be completed within a single season, while large or complex sites — particularly those involving contaminated soil, superfund designation, or extensive hydrological restoration — can span years or decades. Riparia establishes realistic timelines at project outset and maintains consistent engagement for the full duration.

What regulatory requirements apply to reclamation work?

Reclamation is regulated at the federal, state, and local level. Depending on the site, applicable requirements may include Section 404/401 permits, Hydraulic Project Approvals, ESA consultation, NEPA or SEPA review, stormwater permits, and state-specific reclamation or mining closure requirements. Riparia manages the full permitting process on your behalf — identifying what’s required, preparing applications, and coordinating agency reviews.

What does the reclamation process look like from start to finish?

The process moves through six phases: baseline assessment, planning and design, permitting and regulatory review, site preparation, construction, and long-term maintenance and monitoring. Each phase builds on the last — and Riparia manages all of them, ensuring continuity and accountability from the first site visit through project closeout.

Why is Riparia qualified to perform reclamation work?

With the support of MacKay, Riparia has the resources to address not only the technical dimensions of a reclamation project, but also the business, economic, regulatory, political, and legal dynamics that shape how these projects achieve successful execution completion.

What is a superfund site?

Superfund is a U.S. federal environmental remediation program established in 1980 to clean up uncontrolled hazardous waste sites under a “polluter pays” framework that requires responsible parties to fund cleanups. The superfund designation is reserved for the most contaminated and complicated sites in the country. Riparia’s team has worked through the CERCLA process on several large-scale superfund sites.

How is a superfund site identified?

Superfund sites are identified through a structured federal process under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)—which establishes the criteria, assessment process, and National Priorities List that determines which sites receive federal remediation resources.

What is a brownfield?

A brownfield is a contaminated or potentially contaminated property that requires environmental investigation and cleanup before redevelopment can occur. In the Pacific Northwest, much of our former riverfront industrial land falls into this category—including former mills, wood treatment facilities, and manufacturing sites.

How are brownfields identified?

Brownfields are typically identified through property transactions, lender due diligence requirements, and developer environmental site assessments. Conducting a proper Environmental Site Assessment before acquiring or developing a property is the standard practice for identifying brownfield conditions and understanding the scope of investigation or cleanup required.

Environmental Reclamation

Reclamation is the restoration of severely disturbed land including mines, quarries, landfills, industrial sites, and large construction scars where natural ecology has been significantly altered and human intervention is required.

Solutions for Agriculture, Recreation & Development

Before site reclamation, native soils are gone or contaminated, hydrology is disrupted, seed banks are destroyed, and topography has been artificially reshaped. Riparia, integrated with the full civil, geotechnical, stormwater, and ecological resources of MacKay, delivers environmental reclamation services that are buildable, compliant, and designed to make degraded land functional and stable again.

Who This Is For

Private hydroelectric companies facing dam retrofit requirements who find it more practical to pursue dam removal and full site reclamation than bring aging infrastructure into compliance with modern regulations.
Tribal governments who have received grant funding to reclaim former industrial or mill sites on tribal land and need a full-service consulting partner to guide the process.
Local jurisdictions who have secured grant funding to reclaim brownfield or disturbed sites for reuse as open space, recreational areas, or community development opportunities.
Private mining and aggregate firms who need reliable environmental reclamation that meets regulatory requirements, mitigates disturbances, stabilizes soil, and restores sites into safe and productive assets.

What To Expect

Reclamation projects are complex, long-horizon efforts that require coordination across engineering, ecology, regulatory compliance and construction—often simultaneously. Riparia integrates all of those disciplines into a single, managed process so clients have one accountable team from baseline assessment through project closeout. Deliverables across a reclamation engagement typically include:

Topographic, hydrological, geological, and ecological baseline surveys documenting existing conditions and regulatory jurisdiction
Approved construction plans and drawings such as grading plans, layout, planting plans, and erosion control plans
Permit compliance documentation: Section 401/404, USACE compliance, HPA, and ESA consultation
Construction management plans including safety plans, erosion control, and spill prevention
Habitat feature planning: large woody debris placement, snag retention, floodplain reconnection, and native planting palette development
Environmental monitoring protocols and reports submitted to applicable agencies through project closeout

How We Work

1. Establish Baseline Conditions

Riparia and its partners complete the topographic, hydrological, geological, and ecological surveys needed to fully understand current site conditions and identify applicable regulatory jurisdictions.
2. Planning & Design

We develop grading plans and soil amendment strategies, plan habitat features such as large woody debris placement and snag retention, assign a native planting palette and installation schedule, and reconnect the threads of ecological function through comprehensive environmental planning and design.
3. Permitting & Regulatory Review

Riparia prepares and submits all required permits and supporting documentation for federal, state, and local review—including reclamation plans, planting plans, erosion and sediment control plans, and monitoring plans.
4. Site Preparation

Installation of erosion controls, completed demolition, performance of rough grading, invasive species control, and decompaction of soils to create the conditions necessary for successful ecological recovery.
5. Construction

Streambanks are stabilized, wetlands are graded, topsoil is installed, floodplains and hydrology are reconnected, and native species are planted.
6. Maintenance & Monitoring

Riparia develops site-specific monitoring protocols and conducts all required environmental monitoring through project closeout—submitting concise, timely reports to applicable agencies and managing ongoing site conditions.

Why Environmental Reclamation Matters

Reclamation is critical for reversing environmental degradation and restoring contaminated soil and water to safe, functional ecosystems. This process protects both humans and wildlife by removing hazardous substances, protecting communities from pollution, repurposing unused land for productive use, and restoring natural habitats.

Restoring Ecological Function

Reclamation sites like superfund facilities, mines, and heavily contaminated brownfields may never return to ecological function without direct intervention. Reclamation work improves air, water, and soil quality—restoring and making land livable for both people and wildlife.

Public Safety

Unreclaimed disturbed sites present real public safety risks such as landslides, flooding, groundwater contamination, and unstable slopes that threaten adjacent communities and infrastructure. Reclamation reduces risk by directly addressing these hazards.

Enabling Sustainable Development

Reclamation opens the door to new development and community investment—transforming contaminated industrial land into parks, housing, natural areas, and economic centers.

Regulatory Compliance

Reclamation is regulated and often legally required under federal and state law. Working with a team experienced in navigating these requirements protects landowners from costly fines, enforcement actions, and the compounding liability of unaddressed contamination.

Heidelberg Canby Pit Mine Vegetative Reclamation

Riparia provided vegetative reclamation services across this active mining complex—working in coordination with adjacent landowners and ongoing mining operations. Field staff hydroseeded approximately four acres of land across the site, including three artificial berms and a historic floodplain area. We accessed work zones from within the mine, from adjacent properties, and from Highway 99 with appropriate safety measures in place. Successful completion of this project took two weeks, and prevented potential environmental degradation and erosion onsite while also returning a portion of the Mine to native conditions. Execution of this project prevented potentially costly environmental oversight and lawsuits from regulatory bodies and adjacent land owners.
