Projects of Special Interest

  Spirit Mountain Casino

Mater Engineering has performed a variety of engineering services for the Spirit Mountain Development Corporation, an economic development branch of the Confederated Tribes of The Grand Ronde Community of Oregon. The projects to date have included:

  Phase I

Preparation of a complete site development plan for the Spirit Mountain Casino, a 50 acre gaming resort complex, including water and sewer systems, highway under-crossing, road access, parking, wetland delineation and utilities. This project included a separate on-site sewage treatment and disposal system as well as additional storage and distribution facilities for the community water system.

  Subsequent Phases of Development

As an integral member of the design team, Mater Engineering was responsible for engineering design of all aspects of site development on two subsequent phases of the casino expansion, a fine dining restaurant, and a 100 room hotel. In addition, Mater has coordinated wetland mitigation projects and construction of a 7,000 square foot warehouse and satellite parking facilities.

  USDA, Forest Service, Siuslaw National Forest (Indefinite Service Contract)

Mater Engineering has provided, for the past seven years, under an indefinite contract, professional engineering services to the Siuslaw National Forest in a variety of areas at various facilities for which the Forest Service is responsible.

The scope of these projects has included site planning, roadway improvements, sanitary sewer collection treatment and disposal systems, water distribution and grading plans. Site improvements often include wetlands preservation and mitigation, and specialized drainage and stormwater retention features. Mater Engineering has also coordinated the design of numerous structures such as restroom facilities, dormitory living and athletic facilities. Many of these projects have included the design of electrical, mechanical and structural components as well as space planning, lighting, communications, energy conservation.

  Drift Creek Suspension Bridge

Design of a 240 foot span, suspended pedestrian bridge crossing a 100 feet deep canyon, overlooking a spectacular cascading waterfall in a Coast Range old growth reserve. The scope of work included coordination of survey and development of a terrain profile, detailed engineering design and preparation of technical specifications.

  Dunes National Recreation Area

Provided engineering design of utility and site improvements at nine (9) campgrounds within the Dunes NRA. The scope of work included site planning, surveying, abandonment of an existing well and installation of a new well and 20,000 gallon reservoir and associated piping, sanitary collection, holding, and subsurface wastewater disposal facilities for individual campgrounds, power and water utilities and roadway improvements.

  Angell Job Corps Wastewater Treatment Improvements

This project consisted of complete engineering design and preparation of technical specifications for expansion of on-site wastewater treatment plant facilities, development of a reclamation and reuse plan, and construction of a sprayfield wastewater disposal system, including coordination of WPCF permitting process with ODEQ.

  Angell Job Corps Underground Utilities Project

This project consisted of complete engineering design and preparation of technical specification for construction of underground water, power, and communication utilities for the Angell Job Corps Center.

  Crystal Lake Sports Fields

Mater Engineering recently completed the Willamette Park/Kendall Farms Addition Project for the Corvallis Parks and Recreation Department. This project included preparation of plans and specifications for the construction of roadway access and parking for a 125 acre recreational complex including; roadway and parking improvements, stormwater collection and bio-filtration, irrigation plans, multi-use Bike/Pedestrian paths, preparation of Sediment and Erosion Control Plan and ODEQ1200-C permit application.

  Fort Hoskins Historic Park

Mater Engineering recently completed the 125-acre Fort Hoskins Historic Park Project for Benton County Parks and Recreation Department. This project included comprehensive civil design services leading to preparation of plans and specifications for the construction of roadways, parking lots, ADA trail systems, site utilities, restroom and drainage improvements.

As part of the project, Mater Engineering developed a comprehensive base map consisting of a 2' contour interval map produced from stereo aerial photography. The master plan integrated the photographic image with planned interpretive elements, proposed infrastructure improvements, i.e. roadways, pedestrian trails, water distribution facilities, and field survey information. Mater Engineering also prepared a Sediment and Erosion Control Plan and completed the ODEQ1200-C permit application for the project. The project was completed on time and within budget.

  Honeyman State Park Sewer Master Plan

  Honeyman State Park Sewer Collection System

Design of a new 31,000 GPD sewer collection system to serve the main campground at Honeyman State Park. Submittals included bid documentation, plans and specifications, and construction cost estimates. Construction is slated for spring of 1999. Improvements include approximately 9,700 LF of sewer collection mains; small diameter force mains, testing, rehabilitation and/or replacement of septic tanks, and installation of numerous service laterals.

  Grand Ronde Water Systems improvement Project

This project included development of engineering design contract documents. This project was also commissioned by the Tribe to enhance the water system in order to accommodate the future expansion plans of the Tribe and the Grand Ronde community. The project included construction of a 500,000-gallon potable water reservoir and approximately 5 miles of water distribution pipeline as well as spring improvements. The Grand Ronde Water Systems Improvement Project included funding acquisition assistance, development of comprehensive plans and technical specifications, complete bid documents, construction monitoring and contract administration services. This project was partially funded by EDA and FmHA.
