Developer faces scrutiny over risky landfill pavement plan

In a recent government meeting, significant concerns were raised regarding a proposed development project that involves the use of aggregate surface pavements over an unmitigated landfill site. A report from Terracon, dated August 23, highlighted the prohibitive costs associated with the full removal of landfill debris, leading to a recommendation for a surfacing scheme deemed unstable and fraught with high risks, including unpredictable movement of up to two feet.

The developer's proposal lacks clarity on structural loading, and the applicant has not provided any comparable project examples to support their approach. The Aurora Fire Protection District (AFPD) has mandated that the development include an all-weather asphalt or concrete access road and hydrants throughout the site, emphasizing the critical need for a well-integrated design that considers the inherent risks during both construction and operation.

Concerns were voiced about the applicant's failure to adequately address operational risks and the absence of a comprehensive design concept in their submissions. Questions arose regarding the feasibility of designing drive lanes, parking surfaces, and fire access roads without essential vehicle loading information. The potential for significant movement and instability due to the landfill debris raises alarms about the project's long-term viability.

The geotechnical report indicated that new gravel surfacing is necessary, yet the submitted plans call for recycled asphalt, creating a disconnect that could exacerbate stability issues. The report also warned of the risks associated with deep, long-term movement of the landfill debris, which would necessitate frequent maintenance and replacement to ensure proper drainage and structural integrity.

The anticipated erosion and subsidence could lead to increased methane production, further complicating the project's environmental impact. As the meeting concluded, community member Ann Katzberg echoed these concerns, highlighting the potential loss of aggregate surfacing due to wind erosion, which could compromise the strength and drainage of the proposed pavements. The discussions underscore the need for a thorough reassessment of the project to ensure safety and sustainability.
