Request for Proposal Blissful Beach Slope Stability Review - Lacombe County

Located in Central Alberta, Lacombe County is a diverse municipality with a variety of agricultural operations, industrial developments and small businesses, as well as a vibrant petrochemical and oil and gas industry. Lacombe County is also home to three of Central Alberta’s most popular recreational lakes, Sylvan Lake, Gull Lake, and Buffalo Lake. Located along the north shore of Sylvan Lake, the Blissful Beach subdivision includes 25 residential lots, which overlook Sylvan Lake. Topographically, Blissful Beach features a steep southern facing slope which leads to the Sylvan Lake shoreline. Generally, the slope face creates an approximate elevation difference of 35 feet between the shore of the lake and the managed yards of the residential lots. Additionally, several of these residential lots feature lake access structures that extend from homes and yards. These structures traverse the slope, terminating at the lake’s edge. On June 26, 2026, Lacombe County was notified of a slope failure occurring on Lot 24 within Blissful Beach. This slope failure has prompted Lacombe County to conduct a geotechnical risk assessment of the eastern half of the Blissful Beach subdivision. In the time since the June 2026 slope failure, Lacombe County has learned of additional historic slope failures within the subdivision, however, limited information of these historic slope failures exists. Lacombe County requires the expertise of a Geotechnical Engineering Proponent to assess the slope stability risk along the eastern half of the Blissful Beach subdivision. Lacombe County intends to determine subsurface conditions within the area, estimate the historical frequency of slope movement, assess the risk of future slope movement, identify risk factors for existing properties, and receive recommendations for monitoring and slope stabilization efforts.
