• Environmental Planning Spotlight: Tres Rios Environmental Restoration Wins Crescordia Award

    Environmental organization Valley Forward recently recognized the Tres Rios Environmental Restoration project for environmental planning excellence. Construction, mining, and engineering firm Kiewit Western Co. and LSD worked together on the habitat restoration project for the U.S. Army Corps of Engineers and City of Phoenix. Phase III work included a native plant inventory; removal and control of invasive species (primarily Salt Cedar); grading and excavation of the historic river channel; and restoration of riparian and wetland marsh habitats within the active stream area.

    Completed in May 2012, the environmental planning project created 44 acres of new open-water reaches, 10 acres of marsh habitat, and 46 acres of riparian habitat. The Salt, Gila, and Agua Fria river corridors were revegetated with new aquatic plants and cottonwood and willow trees.

    LSD is also the primary designer for five separate trailheads that will provide gateways to multi-use trails leading to the Overbank Wetlands and Flow Control Wetlands at the 91st Avenue Treatment Plant and the Tres Rios Environmental Restoration project.

    Kiewit Western Co. submitted the project for Valley Forward’s review.

  • Logan Simpson Environmental Consultants are Developing Pima County Community Wildfire Protection Plan

    Logan Simpson environmental consultants are developing a community wildfire protection plan that will assess the risk of wildland fire risk to 32 Pima County communities. Nearly 6 million acres are being analyzed for wildland fuel hazards, risk of ignition and wildfire occurrence, local preparedness, and community protection capabilities. The plan will comply with the Healthy Forests Restoration Act of 2003, which is the most effective way for a community to acquire federal funding for fire preparedness and environmental planning.  To date, Logan Simpson has completed 13 HFRA-compliant community wildfire protection plans analyzing more than 15.7 million acres in 160 communities, 118 fire departments and 15 counties within Arizona and New Mexico to determine wildland fire risk.

    A primary objective of the CWPP is to help local governments, fire departments and districts, and residents identify at-risk public and private lands to better protect those lands from severe wildfire threat. Additional functions of the plan are to improve fire prevention and suppression activities, as well as identify funding needs and opportunities to reduce the risk of wildland fire, and to enhance public and firefighter safety. Pima County’s CWPP will meet these objectives at a local level, while integrating with overall federal- and state-level fire planning.

    The environmental consultants at LSD are working with the Pima County Office of Emergency Management to develop the plan, which will also address all risk factors identified by the Arizona State Forester.

  • Logan Simpson Wins IDIQ to Provide Cultural Resources Services to BLM

    Spokane and Vale BLM Districts MapLogan Simpson has been awarded a five-year IDIQ with the Vale and Spokane districts of the BLM to provide cultural resources inventory and evaluation in eastern Oregon and eastern Washington.

    Historic archaeology sites in the Vale and Spokane districts include rockshelters, quarries, campsites, village sites, and rock art sites. Historic sites and structures on public lands in both states include ranches and railroad logging camps, Civilian Conservation Corps sites, and roads and trails.

    Cultural resources tasks covered under this contract include inventories, subsurface testing, archaeological data recovery, and evaluating historic buildings and structures. The cultural resources studies Logan Simpson completes will help the BLM manage cultural resources throughout the Vale and Spokane districts. The BLM manages cultural resources in order to conserve their significant cultural, scientific, educational, traditional, and recreational values for present and future generations.

    The Vale District manages 5.1 million acres of public land in eastern Oregon. The district boundary runs along the Snake River between Oregon and Idaho and includes small sections of Washington and Nevada. The majority of BLM public lands in Washington are east of the Cascade crest in the central Columbia Basin and in the highlands of northeastern Washington along the Canadian border.

    The Vale District includes the Main, West Little and North Fork Owyhee rivers, which fall within a Wild and Scenic River corridor; and segments of the Burnt, Powder, Snake and Grande Ronde rivers. Sections of the Powder and Grande Ronde rivers are also designated as Wild and Scenic Rivers. There are numerous Wilderness Study Areas and Areas of Critical Environmental Concern as well as Research Natural Areas. The Spokane District includes land throughout eastern and central Washington. The Spokane District includes numerous tributaries of the Columbia River: Wilderness Study Areas, and Areas of Critical Environmental Concern.

    According to the BLM, more than 1.2 million acres of public lands in Oregon and Washington have been inventoried for cultural resources.

  • Logan Simpson Landscape Architecture Firm to Assess Freeway Landscape Irrigation Use and Design

    Logan Simpson landscape architecture firm staff and irrigation designers are conducting an assessment to establish irrigation water budgets and irrigation design guidelines for Phoenix-area freeways. We will be studying the water usage of existing freeway segments to determine usage for the representative landscape styles used in the Valley. Our assessment of appropriate water use and design improvements will be the basis of in-progress and future landscape-freeway intergovernmental agreements with local communities. Logan Simpson’s research will then be used to develop a water training manual to improve future watering practices and provide an update the irrigation chapter (released in 1988) of ADOT’s Design Guidelines for Urban Freeways.

    As a landscape architecture firm, Logan Simpson is committed to the sustainable use of limited resources. Logan Simpson and ADOT have a decades-long history of conducting research that promotes sustainable practices and contributes to the long term viability of the desert ecosystem. For more than three decades, freeway landscapes in the Phoenix Metropolitan Area have been watered by drip irrigation. Logan Simpson will help ADOT understand and improve its landscape water use with this baseline study to determine the amount of irrigation water used on ADOT freeway landscapes. By looking at the strengths and weaknesses of existing irrigation systems, our landscape and irrigation designers will then review, evaluate, and provide recommendations to ADOT on potential new systems or upgrades to existing systems. Part of the project will involve researching recent information regarding water needs for desert-adapted plants in order to develop new watering criteria to be used by maintenance personnel and irrigation designers. The results of this research will standardize the amount of water plants receive, improving irrigation efficiency of a precious and valuable resource.

  • Logan Simpson’s Cultural Resources Team Wins Contract for Casa Grande Ruins National Monument

    Logan Simpson’s cultural resources team is assisting the National Park Service revise an existing National Register nomination for the Visitor and Operations Complex Historic District located within Casa Grande Ruins National Monument. 

    The District covers approximately 160 acres and consists of three clusters of building complexes (the visitor compound, maintenance compound, and residential compound), all of which were built by the park service and Civilian Conservation Corps between 1928 and 1963.  Located 50 miles southeast of Phoenix, the ruins themselves are much, much older. Eusebio Francisco Kino, S.J., who founded Arizona’s first Jesuit mission, recorded his visit to the ruins in 1694.

    Logan Simpson’s cultural resources team is working with State Historic Preservation Office staff to develop an appropriate strategy for obtaining concurrence on the document. Our historical archaeologist is revising the draft National Register nomination to address SHPO’s comments and concerns. SHPO will then use the completed nomination to obtain concurrence on the District’s Cultural Landscape Inventory. These documents will assist National Park Service staff in the management of the park’s built and cultural landscape resources.
