Friends and Citizens of Broomfield: WE NEED YOUR HELP!

Our staff, contractors and sub-contractors are struggling to keep people out of the CONSTRUCTION ZONE at the McKay Lake Regional Park Project.

Please stay out of the work area at all times!

While we appreciate that the tunnels and rock slabs look like a lot of fun, they are STILL UNDER CONSTRUCTION. The damage caused by people trespassing has caused unnecessary time and material repairs.

We appreciate your cooperation and help in this important matter.

The remainder of the park is anticipated to open in summer 2018 after landscaping and site restoration are complete.

January Update:
Three jump lines, a drop zone, skills loop, pump track and a smaller “Discovery”/adaptive zone are substantially complete in the 4-acre bike park. Safety and wayfinding signage and about 75% of the permanent open rail fencing have been installed. As of December 20th, the bike park is intermittently rideable by the public as overall park construction and trail conditions allow.
The “Flatiron climbers” and stone bridges were set in the Foothills play zone at the end of September. In October, “prairie dog play” tunnels, the stone “turtle”, climbing boulders, dry creek bed, pergola and rock stairs for the slides were constructed. The picnic pavilion was installed in mid-November and is open to the public. The “Butte” boulders, log bridge, stump trails, stump climbers, two embankment slides, playground ramps and the public art installation project, titled Land Mark, to screen the Xcel Energy gas facilities were completed in December 2017. A second public art installation titled Land Arch was approved by Council, which will bring the total to $100k of public art at this site. Installation of fencing, structural timbers for the “Raptors Nests” and “Beaver Dam”, nature fitness equipment and irrigation is underway. Crusher fines access paths around the adventure playground and nature fitness loop are about 90% complete. Restoration along trails and seeding in nature play areas are in progress. The number of trail users in the open lands area appears to be steadily increasing. The park is anticipated to open in summer 2018 after landscaping and site restoration are complete.

On June 27, 2017, Council approved the GOCO grant agreement and authorized construction contracts with FlowRide Concepts, LLC, for the bike park and Arrow J Landscape & Design, Inc., for the remaining park improvements. Final design of the bike park is underway.

In April 2017, Perfect Patch Asphalt Company, Inc. completed the Zuni Street sidewalk and pedestrian crossing Improvements adjacent to the park site. Critical Path, Ltd. completed a 52-space parking lot in August 2017.

The balance of park improvements includes trails, native landscaping, adventure play areas, a nature fitness course, bike park trails and features, an environmental education/picnic pavilion, adaptive sports features, shade structures, a habitat enhancement buffer adjacent to McKay Lake and site furnishings.

PLEASE NOTE: Natural materials such as logs, boulders, and soil are being imported from other project sites and stockpiled on the property. This results in a substantial cost savings compared to purchasing the materials and enables funding of other site amenities shown in the plan. A large quantity of dirt will be hauled to the site and stockpiled between February 23 and March 17. Trucks will access the site from West 138th Avenue. The dirt will be used to build nature play features in the park. Construction of these features is anticipated to start in summer 2017.

Project Location:

McKay-Lambertson Phase 1 Plan area

The McKay/Lambertson Open Lands Master Plan area is 43.8 acres of undeveloped open land next to the McKay Lake Open Space (which is in the City of Westminster) and located northeast of West 138th Avenue and Zuni Street.

The highest priority features of the overall master plan concept for the area were incorporated into a 16-acre Phase 1 Plan. It includes a balance of active and passive uses immediately west and south of McKay Lake. The intent of the Phase 1 Plan is to provide public recreational opportunities, park amenities, trails, environmental education facilities, and an open space buffer with habitat enhancements

Background and Current Status:

Broomfield’s Open Space, Parks, Recreation, and Trails Master Plan identified the area for potential park improvements and open space preservation and includes regional trail connections across the property.

In 2013, an overall master plan concept was completed for the entire McKay/Lambertson Open Lands area. The City Council directed staff to work with residents that serve on the Parks and Recreation Advisory Committee (PRAC) and the Open Space and Trails Advisory Committee (OSTAC).to create a stand-alone master plan for Phase 1 improvements (Phase 1 Plan) that can be built with only the McKay Landing development contribution toward a regional park ($1,381,083).

In 2014, a Phase 1 Plan was developed with extensive community input and involvement. City Council heard a presentation on the Phase 1 Plan at its Study Session on March 17, 2015.

On August 25, 2015, City Council unanimously approved a consulting agreement with Root House, LLC, for the Phase 1 design. Design processes began in September 2015. Construction documents will tentatively be completed in July 2016. With approval from City Council, staff will then bid the Phase 1 project for construction.

October 22 and 27, 2015 - Broomfield staff met with Root House, LLC and several subject matter experts in the bike park, adaptive sports, fitness and play industries to discuss schematic and conceptual design of features to be included in the Phase 1 Plan. Members of PRAC, OSTAC, and local community members with expertise in these areas were also invited to share their personal experiences, ideas, and comments.

On November 18, 2015, and on April 28, 2016, the PRAC and OSTAC met to review and discuss the McKay/Lambertson Open Lands Phase 1 park design. See online survey results below. Representatives from Root House Studio, LLC presented the plan vision to create something truly unique to encourage people to be active outdoors. The conceptual park design reflects the four major regional landscapes of Colorado; the plains, riparian zones, foothills, and the Rocky Mountains. Natural materials will be used to create unique spaces conducive to many types of outdoor activity and play. Committee members and the public provided valuable feedback about the proposed plan.

An online survey was available in fall 2015 for citizens to comment on the features proposed in the Phase 1 Plan. View survey results and comments or see the total number of votes per feature.

On June 22, 2016, a public open house was held to present construction plans for the project.

Broomfield receives $350,000 from GOCO to build universally accessible nature play park

DENVER – The Great Outdoors Colorado (GOCO) Board awarded the City and County of Broomfield a $350,000 local parks and outdoor recreation grant to build a 15-acre nature play and education facility accessible by children and adults of all ages and social, physical, and intellectual abilities. 

The park overlooks McKay Lake and will include nature play features constructed of natural materials that can be used by children and families and create a close-to-home space to connect with nature.

GOCO funding will help Broomfield build a bike park, nature fitness course, pavilion for environmental education and picnics, a habitat buffer by McKay Lake, and more than a mile of access paths connecting to the existing McKay Lake Trail. The project will also build a nature-inspired adventure playground with play zones resembling a prairie dog burrow, beaver dam, raptor’s nest, spider web, and other elements of nature.

The new amenities will be at least ADA-accessible, with many parts adhering to broader universal accessibility guidelines to ensure residents of all abilities can enjoy the new park.

The project will engage local high school students and leverage partnerships with Craig Hospital, Butterfly Pavilion, Broomfield Open Space Foundation, Broomfield Community Foundation, and the City of Westminster. Broomfield aims to have the park complete by fall 2018.

To date, GOCO has invested more than $500,000 in the City and County of Broomfield, supporting Northmoor Park and Ruth Roberts Open Space, among other projects.

Great Outdoors Colorado (GOCO) invests a portion of Colorado Lottery proceeds to help preserve and enhance the state’s parks, trails, wildlife, rivers, and open spaces. GOCO’s independent board awards competitive grants to local governments and land trusts, and makes investments through Colorado Parks and Wildlife. Created when voters approved a Constitutional Amendment in 1992, GOCO has since funded more than 4,900 projects in urban and rural areas in all 64 counties without any tax dollar support.
