Integrated ESA, Geotechnical, and Hydrogeological Solutions for Habitat Build

Habitat for Humanity – Northumberland hired Cambium to conduct a multi-service project for the design and construction of seven townhomes at Habitat for Humanity’s 0.74ha property in Baltimore, ON.

Habitat for Humanity’s build would include seven two-storey townhomes without basements, a driveway and parking area. The site is irregularly shaped and generally flat.

Specific Cambium tasks included:

A Phase I Environmental Site Assessment (ESA), enabling the client to file a Record of Site Condition (RSC) and meeting Ontario Regulation (O.Reg.) 153/04 requirements. The ESA included a review of available current and historical information on the Site and surrounding properties. The Phase I ESA identified four potentially contaminating activities (PCAs), two on-site and two off-site, contributing to areas of potential environmental concern on-site. Given the findings, a Phase II ESA was necessary to support RSC filing.

Cambium conducted a geotechnical investigation, leveraging a borehole investigation and laboratory tests, for the planned seven townhome units. The investigation assessed existing subsurface conditions, such as soil and groundwater, and provided design recommendations, ensuring structural stability.

Cambium’s Hydrogeology and Wastewater Team conducted a hydrogeological investigation, examining groundwater conditions and adjacent private supply wells. This enabled the team to design a Four-Tank Sewage System for the client, ranging from 9,000L (Tank 2) to 22,000L (Tank 1,3).
