Rocky Mountain Greenway
Extension of Rocky Mountain Greenway North and into Boulder County
The final results from the sampling and analysis plan for the FLAP partnership are available here (link 1 - FLAP Sampling Results) and the final results of the USFWS sampling effort are available here (link 2 - USFWS Final Sampling). In brief, detected values of all contaminants of concern were, without exception, lower than historic values. See summary statistics here (link 3 - FLAP Summary Stats).
The purpose of the sampling protocol was to perform independent confirmatory analysis that the crossing sites and Greenway trail within the Refuge were within regulatory thresholds for construction and recreational use. Given that values for all contaminants of concern were lower than historic values, the sampling protocol accomplished its purpose.
The FLAP partner group will be pursuing an intergovernmental agreement to proceed with the grant and extension of the Rocky Mountain Greenway into Boulder County.
In 2016 Jefferson County Open Space joined with five neighboring open space partners (City of Boulder, Boulder County, City and County of Broomfield, City of Westminster and City of Arvada – collectively referred to as the Partner Group) to submit a grant to extend the Rocky Mountain Greenway regional trails project. This extension links the Greenway from where Phase One currently terminates in Broomfield’s Great Western Open Space, through Rocky Flats National Wildlife Refuge, and into Boulder County. The grant specifically sought funding for trail crossings of Indiana Street and Colorado Highway 128.
The Rocky Mountain Greenway is one of three Colorado the Beautiful statewide priority trail projects that intersect Jefferson County and has also been designated by former President Barack Obama as an official project of America’s Great Outdoors. The vision of the project is to ultimately connect the three Front Range National Wildlife Refuges (Rocky Mountain Arsenal, Two Ponds and Rocky Flats) with Rocky Mountain National Park through an interconnected, multi-use, regional trail system.
Phase One, linking the Rocky Mountain Arsenal and Two Ponds National Wildlife Refuges, is already mostly complete. Phase Two (of which this project is part) linking Rocky Flats National Wildlife Refuge and Lyons is in the planning and study phases, and Phase Three - between Lyons and Estes Park/Rocky Mountain National Park - is still in the conceptual phase.
The elected boards and commissions of the Partner Group have requested that additional soil sampling be conducted to address public concerns regarding possible residual contaminants at Rocky Flats National Wildlife Refuge.
The Partner Group agreed to perform an independent confirmatory analysis (which will include site-specific soil sampling for radionuclides in the areas of disturbance) to corroborate findings by state and federal agencies that conditions at the trail crossing locations at the perimeter of the Refuge boundary are consistent with public health standards for recreational activity. Construction of the crossings into the refuge will occur only if the confirmatory testing results are consistent with the standards which show the site is safe for public use.
After a competitive bid process, Jefferson County has retained Engineering Analytics to perform the requested diligence which will include public engagement and outreach.
News, public meetings, documents and opportunities for comment will be announced on this page so please bookmark to stay informed.
It is important to note that this effort is related to, but separate from, the opening of Rocky Flats National Wildlife Refuge. The results of this effort will not affect the planned opening of the Refuge to the public. This is an independent effort solely related to the linkage of the Rocky Mountain Greenway to planned trails at the Refuge.
Project Timeline (Subject to Change)
- Early July, 2019 – Field work completed by Engineering Analytics staff will be conducted in conformance to the SAP. Actual field work is estimated to be completed within two days.
- September, 2019 – Laboratory analysis of the soil samples for multiple radionuclides will be completed by ALS and has an estimated turn-around time of 6-8 weeks for preliminary results.
- October, 2019 – The draft report from Engineering Analytics is estimated be provided within approx. four weeks of Engineering Analytics receiving laboratory data from ALS.
- Spring – Summer 2020 – Final results published, IGA between FLAP partner group is pursued.
- Fall 2020 – Project design.
- Spring 2021 – Construction.
