Yards Erode Into Infill Excavations

Claire Spicer said an infill excavation beside her Glenwood home in west Edmonton swallowed part of her yard after a July 18 storm hit before shoring was fully in place. Global News reported on August 4 that Spicer said landscaping, grading and part of a retaining wall fell into the pit next door after weeks of near-constant summer rain in the city. Developer Aadesh Projects told the broadcaster it had been working for weeks to reduce risks and prevent more soil collapse. Edmonton’s broader rain pattern has added pressure to construction sites and drainage systems. EPCOR said on July 21 that nearly two months of repeated rainfall had left ground saturated and stormwater facilities struggling to recover between storms, contributing to flooding and sinkholes elsewhere in the city. ### How did one backyard end up sliding into a construction pit? (globalnews.ca) Claire Spicer told Global News that a storm three weeks before the August 4 report caused “the edges of the excavation site” to fall in and pull landscaping from the side of her property into the adjacent hole. She said her husband’s rock work, grading and part of a retaining wall were damaged as the soil gave way. (globalnews.ca) A Glenwood infill site next door was being prepared for an eightplex, and excavation began on Friday, July 17, according to the report. Spicer said shoring work was underway the next day, but severe weather struck on the night of July 18 before the supports were fully in place. ### What did residents say made the site dangerous? Spicer said the excavation remained easily accessible after the collapse and called it “a serious safety concern.” She told Global News that even a child or a dog could get into the pit, which she said held about two feet of water after the July 18 rain. (globalnews.ca) The water stayed in the excavation for four days before it was pumped out, Spicer said. (globalnews.ca) Global News described the unshored site after the storm as looking like “a swimming pool.” ### Who is responsible when infill construction affects neighbouring properties? Aadesh Projects, identified by Global News as the developer of the infill property, said it had been working over the previous weeks to mitigate risk and prevent further collapse. (globalnews.ca) The report did not quote a longer statement from the company in the lines available, but it attributed the response to the developer. The City of Edmonton says residents with concerns should contact the builder first using details posted on the development permit notice, then file a construction-site concern through 311 online, by app or by phone. The city also says immediate danger should be reported to a dedicated phone line, and unsafe working conditions can be reported to Alberta Occupational Health and Safety. (globalnews.ca) ### Has Edmonton already been trying to crack down on infill builders? Mayor Andrew Knack said in April that the city wanted stronger enforcement against what he called a small share of builders who do not follow the rules. An urban planning committee backed a trial that can place repeat offenders under “high oversight,” require training or detailed safety plans, and potentially raise permit fees, according to reporting from April 26. (edmonton.ca) Jan Hardstaff of the Residential Infill Working Group told committee members that some sites had shown improper excavation and damage to neighbouring buildings and yards, according to that earlier report. Knack said administration would report back on the trial within a year. ### Where does this fit in Edmonton’s larger infill fight? Edmonton has been revising its infill rules while trying to add housing in established neighbourhoods. (ca.news.yahoo.com) The city says infill is intended to help meet population growth and housing demand, and it notes that approved zoning amendments from an April 27 public hearing included a lower 9.5-metre maximum building height in the Small Scale Residential zone for permits approved on or after August 1, 2026. City guidance also tells neighbours to document existing property conditions, review the Project Implementation Plan for builder responsibilities, and use 311 so complaints are tracked. The next formal city milestone already on the books is the promised report back on the construction-accountability trial within a year of the April 21 committee decision. (edmonton.ca) (edmonton.ca)
