Williston City Landfill Expansion

Williams County, North Dakota: 

 The City of Williston commissioned a 30-acre expansion of its existing solid waste landfill. Alliance Consulting completed state permitting and designed sediment basins, leachate ponds, drainage and traffic plans, and performed geotechnical analysis. The design included grading, liner, protective covers, and site restoration. It also provided construction management and submitted final drawings of record.

Located by the Sand Hollow Reservoir, the project has been called a “mini-Lake Powell.” The Sand Hollow project required a unique approach to planning to provide recreational opportunities and support residential quality. Restaurants, retail commercial and a wide variety of housing densities are nestled into the natural land forms, leaving clear site lines to the massive ridges and promontories.

The Land Use Master Plan for Sand Hollow was the result of extensive site investigation and analysis, it is the primary tool for formulating both immediate and long-range goals and is the vase of future planning and design strategy. It will be used to generate and evaluate available alternatives and implement hose which are most attractive. The major components of the Land use master Plan are vicinity studies, land ownership, topography, geological features, slope analysis, drainage, soils, BLM analysis, land exchange, views and vistas, and existing facilities and programs. These elements interconnect and correlate to form the backbone of an open space system and environmental planning.


Sienna Hills, 715 acres

Washington, Utah

The Park Masterplan for Sienna Hills Development is a 5 to 6-acre park that will serve as the trail head for the Hell Hole Trail in Washington, Utah. At a major transportation intersection of Washington Parkway and Telegraph Street, the project is planned as a fitness park and fitness challenge course.

Washington City experienced rapid and sudden growth, causing increasing pressure on city infrastructure and planning to accommodate new development while maintain high quality service for all its citizens. Alliance consulting created a GPS interactive program encompassing all City systems and maintenance. It created and permitted with the Utah Department of Environmental Quality a storm water management program for City-wide compliance with NPDES EPA regulations. The program includes development of the City’s ordinances for construction and post construction run-off. Services included extensive analysis, hydrologic engineering, cost estimating, capital facilities prioritization, public comment, ordinance writing, and coordination with FEMA regulators. It also completed a new Grading and Drainage Manual, revisions of the City’s grading policies.

Managed by the Utah State Trust Lands Administration, South Block refers to an area around Exit 2 off I-15 along the Southern Corridor. A major transportation expressway, the Southern Corridor connect eh St George Municipal Airport to the regional communities it serves as well as opening up property to new development.

Alliance Consulting acted as lead civil engineering consultant to coordinate all civil engineering activities on the project. Participate in agencies included Federal Highways, UDOT, Army Corp of Engineers, Federal Fish and Game, and FEMA. Programming, pre-planning, master plan, utility evaluations, studies concept and preliminary design, final design, construction documents, permitting, right of way/easement acquisition, bidding assistance, and construction administration were completed for the master grading and utility design. Utility Master Plans, including sewer water, drainage, grading, and development phasing were completed for the development.

The deign process focused on creating a sustainable community that harmonized with the natural environment and created a sense of belonging for its community members. A land use master plan was developed and the firm completed drainage, transportation, culinary water, irrigation water, wastewater, natural gas, power, telephone and cable television mater plans. The development included all types of housing, from single family homes to town homes and luxury apartments. Commercial development consisted of retail shops, stores, services restaurants, offices and commerce parks. Coral Canyon also has 54 acres of school and church sites. In addition to the residential, commercial and community improvements, there is also a championship 18-hole golf course and resort site and an internal bike and pedestrian trail system connected to local area trails. The gold course and parks in the community feature award-winning water management systems. The development has been recognized for its planning that protects natural views and ridge lines that creates a sustainable aesthetic for the entire community.

Razor Ridge Park is a fully landscaped four-acre community urban fishery. The Lake is approximately 4.8 million gallons and 28 feet deep. The design promotes a system where multiple fish species can survive year round. The lake functions as storage for the Coral Canyon golf course and headwater pressurization for future irrigation in the Coral Canyon community. Backwash water from the Washington City Water Treatment Facility that was previously wasted is now pumped into the lake. The reclaimed water is blended in the lake and utilized as irrigation water for the Coral Canyon golf course.

The Sullivan Soccer Park is designed to showcase the best aspects of Washington City community. A space to gather, it uses the natural aesthetic of the area and accommodates city growth and planning. Its design is an innovative blend of planning that accommodates and uses natural flood water and detention areas to support city infrastructure.

The park is entirely located within the flood plain and designed to collect and contain significant rainfall events. The grass filters hydrocarbons and pollutants from the water as it recedes to the river and the rough rock barriers around the pond serve as a channel. The storage pond is a first class urban fishery that also serves to protect the City’s irrigation usage. The Park also features a picnic pavilion, playground, splash pad and a waterfall/wading feature. The innovative planning of the park helps use flood and recycled water to maintain it.

The Sullivan Soccer Park is a product of vision that integrates people with the environment. Historically, the property had been a dumping ground and fire risk with overgrown tamarisk and grasses. It is now an attractive and vital center for Washington City.

The property is now an example of best use for the community. It stores, cleans and protects city water, preserves the rugged and unique beauty of the community, and provides a central place for the neighborhood to enjoy their local area with a fishing pond, picnic areas, soccer fields with operational score boards, bleachers, and concessions stands, and serves as the trail head for the premier Virgin River Trail System.

The Virgin River Boardwalk Trail is a 2-mile trail section that creates a vital connection between the southern trail system of St. George and Washington and the northern trails of Sienna Hills and Coral Canyon. Ultimately, it will be a crucial part of the complete trail system to Zion National Park.

Some significant design challenges included permitting from multiple state and federal agencies including city planners, the Bureau of Land Management, the Virgin River Program, U.S. Fish and Wildlife, the Army Corp of Engineers, Federal Emergency Management Agency, and permissions and easements from private ownerships.

Due to slopes in excess of 1:1 and the river’s proximity to the slopes, the trail planning called for a section through weeping wetlands and sensitive river environments. It features a portion of wood boardwalk that spans protected wetland areas set against the steep bank and cliffs that seep water year-round.

The project was a 3-year coordinated effort to build cooperation between all partners to answer environmental challenges and complete the trail construction.
The Boardwalk Trail opens up over 2-miles of beautiful and unique southern Utah landscape to allow visitors and community members to enjoy the beauty of their natural setting.
