• West Box Elder Coordinated Resource Management Plan

    Logan Simpson’s Utah planning staff managed the project design and technical planning roles for this complex countywide planning process to carefully coordinate resource management across all the city, county, state, and federal planning occurring in the western portion of Box Elder County, Utah. The large and sparsely populated part of the county has a ranching-based economy, but lacks water and other amenities that typically enable self-sufficient and sustainable communities. The area’s mosaic of land ownership complicates land and resource management. With imminent decisions on federal actions related to grazing allotments and watershed protection, local residents turned their efforts to a planning process that would collaboratively focus key conservation issues and freshly engage stakeholders and inter-jurisdictional partners. Our Utah environmental planning team’s efforts helped everyone to understand, and for the first time coordinate, the dozen or so key government land-use plans in effect in the area. In these meetings, residents discussed challenges and conflicts, helped articulate desired future conditions, and built the framework for prioritizing goals for resource management across the landscape. As the team’s public involvement and project planning lead, Logan Simpson led extensive community-based scoping that included face-to-face meetings with stakeholders as well as several facilitated community meetings. We also led the land use and socioeconomic planning processes. The plan earned a Public Lands Foundation Landscape Stewardship Award.

  • Great Basin National Park Vegetation Map

    Logan Simpson assigned a team of 12 biologists to determine the different plant community associations (based on the US National Vegetation Classification) that are present at 900 accuracy assessment plots distributed across Great Basin National Park in Nevada. Biological resource specialists navigated to randomly generated locations and recorded precise GPS data, the dominant plant species, vegetal cover by strata, slope and aspect, and photographed the plots. Teams used high-resolution aerial imagery to identify the target associations to sample. Fieldwork was executed efficiently by using ArcGIS-driven modeling, which determined the safest and best cross-country routes through extensive wilderness areas in rugged terrain, which at times reached more than 13,000 feet in elevation. The final report enhanced the vegetation map of the park and predicted vegetation map classes at 84 percent accuracy.

  • US 60 Gonzales Pass

    As a landscape architecture firm, Logan Simpson has a long history of designing highly sustainable, context-sensitive transportation projects. This award-winning project involved widening approximately 10 miles of US 60 near Superior, Arizona to four lanes. Logan Simpson inventoried more than 35,000 native plants and developed revegetation plans incorporating salvaged trees, various cacti, and a native seed mix. Discussions with the Tonto National Forest determined the appropriate density (and number) of replanted materials. The revegetation at Reymert Wash included planting of salvaged trees to satisfy mitigation requirements in the EA and the CWA Section 404 permit cactus ferruginous pygmy-owl habitat connectivity. Logan Simpson’s Arizona landscape architecture design staff also developed extensive contour grading plans for the cut slopes and designed erosion/sediment control BMPs to meet NPDES requirements. The project earned a President’s Award (Best of Show) Valley Forward; an ADOT Partnering Award; and a Top 10 Project Award from Roads and Bridges Magazine.

  • Verrado Heritage Pool and Park Complex

    This three-acre community pool and park is located in the heart of the Verrado Community Heritage District. Landscape architecture firm Logan Simpson led the design of the pool and the amenity areas, including grilling areas, a fire pit, and several gathering spaces around the pool. The pool itself is a resort-style layout with two levels. The lower level is a wading pool with a beach entry and splash pad that is tailored to kids. The larger pool on the upper level has a beach entry and several subareas for relaxing and play. The surrounding landscape architecture design will become enhanced desert garden oasis that help visitors to the Heritage Swim Park feel like they have escaped to a top-end resort. The Heritage Swim Park is full of inventive and stylish amenities that transform the community pool into a resort oasis. Landscape areas and shaded seating areas are close to the pool’s edge to increase visibility of the pool area and offer intimate spaces. The lower level pool is tailored to young children and their parents offers an expansive water play experience with resort-level detail. Even some of the furniture in this space is sized for kids. Beyond the pool, the resort experience continues with garden paths, BBQ grills, ramadas that open to grassy areas, a fire pit seating area, and a community gathering space with one end adjacent to the Heritage Pavilion.

  • Cross Canyon Trail Cultural Landscape Inventories and NRHP Nomination

    Logan Simpson’s Arizona cultural resources specialists completed an NRHP nomination for the Grand Canyon Cross-Canyon Corridor Historic District. The corridor includes the exceptionally diverse landscapes of the Bright Angel, North Kaibab, South Kaibab, and Colorado River trails—which collectively represent approximately 30 miles of maintained trails within the Grand Canyon. The inventory includes all buildings, structures, and objects associated with the facilities and campgrounds along these trails, including Yaki Point, the Bright Angel and Cottonwood Campgrounds, Roaring Springs, and the distinguished Phantom Ranch landscape. The Phantom Ranch landscape includes cabins, a lodge, a recreational center, and a shower house designed by renowned architect Mary Colter, as well as numerous buildings and structures constructed by the CCC during the 1930s. Logan Simpson’s landscape architecture, historic preservation, and archaeology staff collaborated with the park’s cultural resources specialist and the NPS Intermountain Region historical landscape architect to ensure thorough and accurate documentation of the condition and historic integrity of the trails’ character-defining features. The inventory and NRHP nomination provides Grand Canyon National Park staff with the information necessary to make decisions regarding preservation, interpretation, and resource management.

  • APS Cultural Resources Survey

    In a project of extraordinary scale, Logan Simpson’s cultural resources consultants surveyed approximately 5,000 miles of Arizona Public Service (APS) 69kV to 500kV transmission lines in Arizona and New Mexico prior to routine maintenance, emergency maintenance, vegetation clearing, and new construction. We coordinated with numerous land management agencies and Native American tribes. Our cultural resources consultants also provided site avoidance flagging and archaeological monitoring during vegetation-maintenance activities to avoid adverse effects to NRHP-eligible sites. Our cultural resources specialists developed SHPO-compliant field recording methods for efficiently preparing site forms for multiple agencies. We recorded field data using GPS to submeter accuracy for easy integration into APS’s GIS database and followed strict safety procedures. Our work allows APS to efficiently manage environmental issues within its transmission line corridors and provided an unprecedented body of data for conducting archaeological research across much of the Southwest. Logan Simpson was named APS’s Diverse Supplier of the Year in 2014.


  • Red Mountain and Canaan Mountain Wilderness Areas

    Logan Simpson served as the cultural resources consultants for the BLM St. George Field Office as it developed management plans for the Red Mountain and Canaan Mountain Wilderness areas, which are adjacent to Zion National Park in Utah. Our archaeologists conducted archival research and an intensive-level cultural resources inventory on 2,170 acres to identify the frequency and types of cultural resources. The high-elevation inventory areas (above 7,300 feet) were bounded by sheer cliffs on multiple sides. To overcome the logistical difficulties of the working within these remote, rugged areas, Logan Simpson used pack animals to carry equipment and food/water into the Red Mountain area then cached the materials at temporary supply points. Camp sites were moved on an as-needed basis to balance access to supplies and the work area.Logan Simpson recorded 57 archaeological sites within the Red Mountain area, including numerous large prehistoric artifact scatters and one historic irrigation ditch carved into the natural sandstone bedrock. A historic sawmill and a windlass used to lower timber down the sheer 2,000-foot cliff that bordered the inventory area were recorded within the Canaan Mountain area.

  • Tres Rios Environmental Restoration

    Logan Simpson was part of a multidisciplinary design build team responsible for the environmental restoration and rehabilitation for an approximately 1.5-mile reach of the Salt/Gila River between 107th and 119th Avenues  for the US Army Corps of Engineers, as sponsored by the City of Phoenix. The long-term goal was to restore native Sonoran Desert aquatic and riparian habitats along this Salt/Gila River reach. Multiple iterations of hydraulically-modeled, site-sensitive riverbed recontouring (grading) plans were prepared and evaluated for hydraulic efficiency and cost effectiveness.  The plans were developed with the intent to preserve important existing Cottonwood/Gooddings willow groupings that had been inventoried by Logan Simpson and known threatened and endangered species (Yellow-billed Cuckoo and Southwestern willow flycatcher) habitats, to replicate as closely as possible historic braided stream patterns and cross sections, to seamlessly accommodate storm drainage inflow sources into the overall restoration plan, and to create  sustainable, stratified native aquatic and riparian habitats. The project included the restoration of riparian and wetland marsh habitats, open water, and other upper terrace floodplain habitats along the River reach and the removal of exotic, invasive and/or noxious plants (predominantly Salt Cedar). Logan Simpson led the watercourse layout and alignment study, was the lead restoration designer, developed the restoration chapter of the Design Analysis Report, and prepared native plant inventories, landscape and wetland restoration plans, a SWPPP, a spill prevention control plan, and O&M guidance to assure long term success of the project.

    In addition, Logan Simpson was the primary designer for five trailheads that provide gateways to multiuse trails. We coordinated environmental artwork (betterments) that were integrated at various vantage points. Logan Simpson worked closely with the design builder and general contractor, engineers, specialty contractors, USACE, and the City of Phoenix to develop a project that met flood control, habitat and ecosystem restoration, effluent conveyance, and water reuse goals. The project has won numerous awards, including an Award of Excellence from the American Society of Landscape Architects (Arizona Chapter); APWA Public Works Project of the Year; an Honor Award from Missouri Chapter of the American Council of Engineering Companies; a Merit Award AND Design Excellence Award from the Design Build Institute of America; an Arzona Forward Crescordia Award; and a Build Arizona Award from the Association of General Contractors (Arizona Chapter).

  • BLM Jordan Resource Area Visual Resource Inventory

    Logan Simpson completed a visual resource inventory for the Jordan Resource Area encompassing the range of landscapes within southeast Oregon’s Basin and Range and Columbia Plateau Physiographic Provinces. This inventory area covers approximately 3 million acres of varied landscapes, ranging from small agricultural communities and wide-open grasslands, to expanses of black lava flows and the deeply incised Owyhee River Canyon. The inventoried lands are largely undeveloped, resulting in vast views of few cultural modifications. Research and public outreach for this project resulted in few planning documents regarding the protection of scenery and scenic viewsheds, but revealed articles and tourist information for popular destinations throughout the region, including the Owyhee Backcountry Byway, Jordan Craters, Rome Cliffs, and numerous overlooks. This information was taken into consideration during visual sensitivity ratings and resulted in well-informed and accurate delineations of differing sensitivities within the resource area.
