An area of open space located in Westminster is where one of Colorado's largest off-leash dog parks is located, but the city is considering changes to the area that have residents upset. “We are recommending that we return the majority of that area to an on-leash opportunity, which is consistent with our open space,” said open space superintendent Joe Reale. The Westminster Hills Open Space is 420 acres of space available for dogs to run, fetch and play off-leash. A new proposal from the city's Parks, Trails, and Open Space Department would drastically reduce that off-leash area, potentially limiting it to a small corner of the existing space. The city meeting on March 6 from 6:30-8:00 p.m. will present four concepts for community feedback that incorporate many of the ideas that the city received from residents earlier this month.

More than 1 million people visited the park last year. “We are coming to the conclusion that our dog off-leash opportunity is having a negative impact on those natural resources, so we are recommending at this point that we change the designation to an on-leash requirement.” Dog owners who regularly use the off-leash park are disappointed with the potential changes.
