AB-2025-04742 - ITT-25-011-RVC Langdon Bypass Drainage Improvement-Tender Final

The Hamlet of Langdon is located approximately 16 km east of Calgary, on the southeastern side of Rocky View County and just south of Glenmore Trail (Highway 560). The topography of the upstream catchment area and Langdon itself is flat, with the main municipal drainage ditch running generally east through the Hamlet. Due to the flat topography, the existing ditch has low grades and is known to experience standing water regularly. All systems in Langdon eventually release via the ditch into Weed Lake, which is located northeast of the Hamlet. This project supports critical stormwater management within and around the hamlet by diverting stormwater from the upstream catchment before entering the hamlet's main municipal ditch system. The stormwater will be intercepted on the south side of Glenmore Trail and conveyed to Weed Lake through a piped system. The municipal ditch just south of Glenmore Trail will be utilized as an emergency overflow escape route for extreme storm events greater than 1:100 years.
