The U.S. Department of Energy (DOE) proposes various pedestrian safety improvements at DOE’s South Table Mountain (STM) campus of the National Renewable Energy Laboratory (NREL) in Golden, Colorado.

The proposed project would include three hardscape improvements to address several pedestrian safety issues outside of the Vehicle Technologies Integration Facility (VTIF), the Outdoor Test Facility, and the Solar Energy Research Facility (SERF). The improvements outside of the VTIF would consist of the addition of a 75-foot long 4-foot wide sidewalk along the southwest and west sides of the building to provide safe maintenance access to outdoor equipment pads. At the OTF, a new bus stop is needed to drop off and pickup shuttle riders. Currently passengers must wait by the roadway, which provides an unsafe condition. A 10-foot by 20-foot concrete pad for a bus stop would be built along Denver West Parkway. Additionally, a bus shelter currently in storage at the Joyce Street Facility may be installed at this location. Hardscape improvements outside of the SERF would include a 90-foot long 6-foot wide sidewalk on the southwest side of the building near the pedestrian bridge crossing the middle drainage. This would provide a more direct pedestrian route to SERF from other buildings and prevent employees from walking on vegetation. All three hardscape improvements would occur in previously disturbed areas, and the Project Management Plan and location maps are uploaded to the PMC. These activities would occur in Site Development Zone 3 – West Campus and Zone 4- Central Campus.
