This presentation covers the design of a Recreational Vehicle (RV) park for Yellowstone Airport employees. Yellowstone Airport is located in West Yellowstone, Montana. The site location is on the airport property and the RV park design will be compliant with Federal Aviation Administration (FAA) regulations. The project engineering design will include features such as a new road, RV sites layout, water and wastewater systems, and electrical systems. These features will provide functioning RV sites with running water, electricity, and wastewater outlets. The intent of this project is to provide a design meeting the needs of the Yellowstone Airport and to comply with regulatory requirements for all project parameters.

Littlebrook Creek is a tributary of Thornton Creek, located in North Seattle. Under NE 120th Street, between NE 35th Ave and 36th Ave, there is a culvert that runs perpendicular under the street that is collapsing. This culvert is also a barrier to salmon passage during spawning season because the culvert invert is too high above the creek bottom on the downstream side. A new long-term solution needs to be installed, otherwise the culvert could fail, causing NE 120th Street to collapse which would result in the damming of the stream and pooling of water from the stream potentially overflowing into neighbors’ yards. This project will consist of designing a replacement culvert. It will include removing the asphalt road, excavating soil, and removing the current thirty-inch concrete culvert in order for a sustainable replacement to be installed. The creek will have to continue to flow throughout construction which means that water will have to be dammed upstream of NE 120th Street and the water pumped across the street and released downstream, allowing for a dry construction area. Measures will need to be taken to prevent debris from construction contaminating the stream. Through diverting the water from upstream to downstream it will help with contamination prevention. Construction must also take place in the window of time that will not impede salmon migration.

Canyon Ferry Lake, east of Helena in Broadwater County, Montana was formed in 1954 when Canyon Ferry Dam was constructed across the Missouri River. Lakeshore residents have reported excessive erosion during recent years. In 2012, the Bureau of Reclamation produced a management report with recommendations for erosion mitigation, but no studies have been done on Canyon Ferry to determine relative erosion risk and site-specific factors driving shoreline processes. This study is an analysis of shoreline erosion around Canyon Ferry Lake. The first component of this work included the classification and mapping of shoreline morphotypes lake wide. This allowed for the identification of areas subject to higher erosion risk based upon the driving forces that resulted in differing shoreline morphology. The Steep Cliff and Sloped collectively accounted for 46.9% of shoreline length lake wide, highlighting the need for erosion mitigation. The shoreline morphotypes were then mapped in relation to geology or rock type, and also beach aspect to determine whether these two factors are influencing the presence of given morphotypes, and by extension, whether these factors influence relative erosion risk at Canyon Ferry Lake. The strongest relationship was between Steep Cliff and Tertiary sedimentary rocks. Relationships between morphotype and aspect (wave energy) were inconclusive.

The Livingston Airport (LVM) is located in Livingston, Montana in Park County. The population is roughly 8,000 people, however, due to its location, the airport has a high volume of tourist traffic. The high demand calls for the airport turnarounds to be expanded to accommodate larger aircraft. The expansion designs met all Federal Aviation Administration (FAA) requirements for aircraft loading up to 45,000 lbs for a single wheel and 99,999 lbs for dual wheels. The project meets design criteria while minimizing environmental impacts and providing a sustainable option. Four expansion alternatives were analyzed to ensure the needs of the airport were met. Calculations and designs were based on a current geotechnical report and site survey. The expansions and improvements to the turnarounds will allow for plane maneuvers to be in accordance with regulations while keeping all pilots and passengers safe. The turnaround improvements will help maintain and improve tourist numbers and provide revenue for the Livingston area.

This project is to upgrade and improve an existing unpaved parking lot in front of the Lewis and Clark County (LCC) Public Works Administration Building. The overall design will focus on providing hard-surface paving and implement Americans with Disabilities Act (ADA) provisions in the design. The first stage of design was to complete field work and soil sampling. This involved a site topographic survey and a geotechnical investigation. The geotechnical investigation included digging into the subgrade and collecting soil samples. The samples were tested for various engineering properties to be used in the design. The second phase was preliminary analyses to evaluate several potential design options, determine construction quantities, and calculate preliminary construction costs. These analyses showed us that the most practical final course of action in terms of cost and effectiveness was paving with a 3-inch-thick asphalt surface. The project will include ADA features, and parking spots will be delineated with painted striping. The construction phase of this project will have to consider the safety and health risks of the workers and the surrounding citizens. Moreover, the runoff path of any hazardous spills or water was designed to ensure that nothing potentially environmentally toxic leaves the property, and spill kits will be readily available so there is no groundwater contamination. Due to the deteriorated state of the existing gravel lot, this new asphalt pad will be a welcome upgrade that will increase safety and accessibility for all users.

In this project, our team, Squared A-Way Engineering, is redesigning a residential deck for a house located within the City of Helena near the base of Mt. Helena. The current deck structure has exceeded its design life and is in disrepair. Based on an assessment of the existing deck, it no longer meets current building codes and permitting requirements for the state of Montana. With that said, the owner is no longer comfortable using the deck for outdoor gatherings. Our team has produced a design that replaces the entirety of the structure with new and improved material and adds visual and structural enhancements. This presentation is an illustration of our final design, including cost estimate, analysis, drawings, and calculations.
