SAN DIEGO (FOX 5/KUSI) -- On a popular city trail in University City, two large sinkholes have formed. Residents are voicing their concerns and pleading with city leaders to fix the problem before it gets any worse. “It was pure shock to see how big this hole was,” said Amy Nielsen, a homeowner. “I just fear for the rest of my home here,” Jason Nielsen added. Hurricane Milton down to Category 3 but remains ‘a grave threat’ After a period of heavy rain in late March, two large sinkholes opened up in Standley Park, just yards away from Jason and Amy Nielsen’s home. “You could actually hear the ground opening and falling in,” said Jason. The sinkhole was 20 yards from his property line. “I don’t know how much more this ground is going to give way when the next storm comes,” Jason said. Officer in Escondido shooting identified The street sits at the bottom of a hill, where water naturally flows. “The water has nowhere to go. We are the main drainage for this neighborhood and now it’s going out a broken storm pipe into a huge hole,” Amy said. The Nielsens have reached out to District 6 Councilman Kent Lee, the City of San Diego Park and Recreation Department and the city's Storm Water Department. In an email, Lee's office said the site is on a list of sinkhole locations under review. “Due to city funding, or a lack of funding, they don’t think they can do anything, they’ll monitor if another storm arises,” said Jason Nielsen. The situation has left the Nielsens feeling helpless, and as if they are just waiting for a disaster to happen. “I don’t feel like the city is doing anything at this point,” said Amy. Amy is also concerned about the public health risks associated with a sinkhole. “It will just become a cesspool for mosquito larvae and everything that they bring,” said Amy. FOX 5/KUSI has reached out to Councilmember Lee's office and the city's Storm Water Department. The city sent FOX 5/KUSI the following statement: "The sinkholes are the result of deteriorating metal pipes underground that need to be replaced. We have added this site to our list of future repairs and will monitor it closely before and after rain events to assess its condition until it gets fixed. As we do with all stormwater infrastructure issues we are monitoring, we will continually reassess site conditions to ensure that our resources are being used to address the highest priority conditions considering threats to public health and safety."
