OSMP Master Plan
Open Space and Mountain Parks has kicked off a long-term effort to establish a community-supported plan that will guide the management of the community’s open space over the next decade and beyond.

South Foothills Trail
March 19, 2018: Trail repairs are under way! Initial trail grading and re-surfacing are occurring on the south end of the project.
March 7, 2018: The project began on Wednesday, March 7. The Foothills South Trail from the Utica Ave. access to Four Mile Canyon Creek is closed 7 am-5 pm Monday-Friday.
Starting March 7, 2018, OSMP will repair 3,400 feet of the Foothills South Trail from the Utica Avenue access north to Four Mile Canyon Creek. This project will repair damage from the 2013 floods, which has resulted in eroded trail conditions and loss of trail surfacing material – creating an uneven trail surface, drainage issues, and seasonal muddy conditions on the trail. This is one of OSMP’s last two flood-related trail projects that is eligible for FEMA reimbursement.
OSMP will institute closures along the Foothills South Trail and the Locust Ave. access trail to help complete this project. Closures will occur from 7 am to 5 pm, Monday through Friday, and the project is estimated to take approximately two months to complete. The trail is expected to be open on evenings and weekends. Paragliding access to Wonderland Hill is available via the Utica Ave. trail access or the Wonderland Lake area. Alternate routes around the closure area are available to the east via multi-use paths and sidewalks for hikers and runners, and via streets and multi-use paths for cyclists.
This project does not include the installation of a new bridge over the Four Mile Canyon Creek crossing. The bridge project is currently going through engineering and design, and will require several permitting and review processes.
Starting as early as Monday, Feb. 12, OSMP will begin work to repair Boulder Falls. During this repair project, OSMP will rebuild gabion walls – which are rock baskets used to catch sediment coming off the hillside – and conduct repairs to stabilize the trail. The project also will improve trail tread. Boulder Falls remains closed. Because of equipment needed to conduct these repairs, there will be no parking available at Boulder Falls pull offs along Boulder Canyon.
