Through multi-disciplinary team coordination, RPA’s Natural Resources Services Group provides a full range of science and engineering services - initial site investigation, environmental assessment, design and permitting, construction contract administration, and site monitoring.
A team approach to site investigations and site infrastructure development is a mainstay of our Natural Resources Services. Our project diversity brings significant resourcefulness to the design table. We are well versed in waste disposal technology and design processes, having worked on over 35 projects involving mine reclamation, and solid and hazardous waste remedial design. Hydrogeologic investigations are often conducted in conjunction with other RPA Service Groups.
Our wetland designs involve flood control, highway mitigation, wildlife habitat, municipal treatment and mine drainage treatment. We respond quickly with concise, comprehensive reports, and innovative practical solutions.

Eastern Montana Facility Condition Assessment
Client: U.S. Fish & Wildlife Service
The US Fish & Wildlife Service conducts facility condition assessments (FCA's) as a means to track maintenance needs on government properties. RPA was assigned the larger assessments in Montana, amounting to 38 sites covering six counties. Widely dispersed FCA's were located in four different National Wildlife Refuges and the Charles M. Russell Wetland Management District.
The assessment effort followed both FWS protocol as well as the requirements of ASTM E2018 99. Thorough research prior to on-site investigations was conducted, including water rights, drainage data, groundwater information and water quality. Facility history was compiled from interviews of FWS staff and the largely remote sites were initially located with GPS. Available USGS Quadrangle topographic mapping and air photographs were used as a base for site mapping and field sketches. Maps and sketches were developed in house for inclusion in the report for each site and the condition of each site was documented and photographed. Water samples were taken and analysis results included in the reports. Work included data base management of the investigation information. Both maintenance and replacement costs were compiled for each facility.
Many of the sites were large impoundments for wetland wildlife habitat. The impoundments and related water control structures were thoroughly investigated. Water is a critical item in this arid environment and the valuable wells located in these refuges were also investigated as part of the project. Our team subconsultant, Eclipse Engineering Inc., completed the detailed structural analysis on the large concrete structures (bridge, weirs, etc.).
“The cost info you provided is great. Thanks again for providing an excellent product at a reasonable price for this difficult task. The customer (Facility Management Coordinator) was extremely happy with the detail and quality of the reports you provided to the FWS.”

Montana State Veteran's Cemetery Expansion at Fort Harrison
Client: Department of Veteran's Affairs, Department of Military, State of Montana
RPA is the prime consultant responsible for master planning, design and implementation of all site related infrastructure, site layout, walls, entry monuments and landscape irrigation. Project master planning work began in September 2012 and the first phase of construction is scheduled to be completed in spring of 2014. All design elements have been developed in accordance within the Veteran Administration’s master plan and design standard’s guidelines.
Key Project Elements:
Holter Lake Campground - Boat Ramp and Docks
Lewis & Clark County, Montana
Client: Bureau of Land Management
The Holter Lake Campground is located about halfway between Great Falls and Helena Montana on Holter Lake an impoundment on the Missouri River. Campground visitation is currently about 50,000 visitors per year with projections of up to 350 boat launchings per day. The design includes a 65 foot boarding float between boat access ramp lanes, an 88 foot courtesy dock, and a 235 foot main overnight dock. The layout accommodates 43 overnight moorings and is designed for winter seasonal removal of the floating dock sections.
Trails to the docks were routed to provide ADA accessibility and minimized impact on the existing facility. The paved trails, concrete stairway, dock abutments, shoreline stabilization and anchoring system designs were complicated by fill type soils and shallow groundwater. The existing boat ramp was being undercut at the toe and required deepening and lengthening in addition to adding ramp access lanes. The water depth at the ramp toe required that sheet piling be installed for dewatering during construction. RPA coordinated with a number of structural, geotechnical, dock and ramp specialists to facilitate the design.
Design alternatives were compiled into reporting that also addressed cost estimates. Design complications included significant wave and ice loads on the dock and shoreline stabilization. RPA accommodated multiple design reviews and provided complete plans and specifications provided for bid. The construction cost of the project was about $1.1M. The design work was completed through RPA's IDIQ contract with the BLM Montana and Dakotas region.
