In recent years the Alderfer / Three Sisters Open Space in Jefferson County has seen an influx ofvisitorship. This increase in popularity has resulted in cars parking on adjacent roads causing safetyconcerns for the surrounding community and park visitors alike. Valerian was contracted to assist inthe design of a new parking lot, trail head and restroom area, and associated trail improvements. Theproject includes the decommissioning of an old dirt parking lot and the preservation of the historicAlderfer barn.
Valerian worked with Jefferson County Open Space (JCOS), the project architect, and engineerto develop the site plan improvements for the Alderfer Trailhead. Valerian worked through the conceptdesign of the site amenities to orient the parking lot and restroom in a way that preserved the existingviewsheds and honored the historic barn. As a part of this process, Valerian created Lumiongraphics of the project site to fully portray the potential impact to the viewshed and the existing naturalfeatures. Once the overall concept design was settled on, Valerian coordinated with the project engineer to develop the parking lot into a permeable paver lot to meet the water quality needs of the site. Valerian has developed the planting plan for the site using native plant material and has detailed site specific trailhead amenities. The project is slated to begin construction in fall of 2023.
