R/W Appraisal & Acquisition
College and 11th Street Roundabout
Client: City of Bozeman, Montana
Robert Peccia and Associates (RPA) provided design, right-of-way acquisition assistance, and full-time construction administration services on this project. The previous intersection of West College Street and South 11th Avenue consistently experienced failing level of service during periods of peak hour traffic demand.
The new modern single-lane roundabout significantly improved vehicular traffic flow while incorporating a widened shared-use pathway around its perimeter. The project required design and development coordination with Montana State University facilities planning staff and the Montana Department of Transportation District and Systems Impacts Departments as the project is located on the State’s urban routes.
RPA provided full design and development including bid plans and specifications and construction management. The electrical lighting plan and layout included installations to allow the city to install future Rectangular Rapid Flashing Beacons (RRFB’s) at each crosswalk should they desire to heighten driver awareness of pedestrians in the crosswalk landings.
Four Corners - North
Gallatin County, Montana
Client: Montana Department of Transportation
RPA provided engineering and environmental services for this reconstruction and widening project east of Bozeman, Montana. The purpose of the project was to increase the roadway capacity, improve safety and provide pedestrian and bicycle amenities. Turning to and from the existing narrow and congested 2-lane roadway had become difficult and dangerous, conditions resolved by the new modern 5-lane facility. The heavily-used intersection of Jackrabbit Lane and Huffine Lane was reconfigured and expanded, adding additional turn lanes, a new traffic signal and ADA access.
Project activities completed by RPA included: survey, environmental investigation and document, geotechnical evaluation, right-of-way design, hydraulics and irrigation analyses, traffic analysis and planning, traffic signal design, and bicycle and pedestrian path and underpass development. Late in the design process, the client requested the analysis of three multi-lane roundabouts. Ultimately, through the public information process, the roundabouts alternative was withdrawn, and RPA designed traffic signals for the three intersections.
Whitefish Downtown Infrastructure Improvements Project
Client: City of Whitefish, Montana
RPA's professionals performed civil engineering design, surveying and construction administration on the complex five-year project. The construction – five phases completed over three years in the shoulders seasons of spring and fall – began in September of 2009. Challenges facing construction were that it could not take place during winter because of the cold and snow nor in the summer because of potential impacts on local downtown business during the tourism season.
This lengthy and sometimes controversial project involved the complete reconstruction of Central Avenue from Railway Street to Third Street, Third Street from Baker Avenue to Spokane Avenue and First Street from Baker Avenue to Spokane Avenue. Although construction activities caused some temporary street and sidewalk closures, the contractor provided traffic control and an accessible route to each business at all times. Residents received periodic progress newsletters throughout the construction, outlining upcoming construction activities and summarizing the overall project.
The finished urban project now has new sidewalks, a new roadway, trees and landscaping with an irrigation system, street lights, benches, bicycle racks, sanitary sewer, and updated water and storm drainage utilities. RPA (prime consultant) provided the civil engineering and construction administration for the civil work for this project. Bruce Boody Landscape Architect, Inc. (subcontractor) completed all the landscape design and Kingdom Builders Engineering, Inc. (subcontractor) completed the street lighting electrical design.
Beartooth Scenic Highway Reconstruction Project
Park County, Montana
Client: Federal Highways Administration - Western Federal Lands Highway Division
Phase I of the five mile $11.2 million dollar reconstruction project began in May 2004 for the Western Federal Lands Highway Division (WFLHD) of the Federal Highway Administration (FHWA). The northeast entrance to Yellowstone National Park on US Highway 212 between Cooke City, Montana and the Montana/Wyoming State line two-lane rural highway was being upgraded to meet current AASHTO and FHWA design standards and to improve safety and driveability. The project improved the horizontal and vertical alignments and increased the width to accommodate recreational vehicles. Other improvements include turnouts and interpretive locations, improved access roads, campground improvements, roadway relief pipes, a concrete cantilever retaining wall, and new signs, pavement markings, and guardrail to improve safety.
The proximity of the project to Yellowstone National Park, coupled with the sensitive pristine environment, made environmental considerations a key element in project’s success. Design features such as a fish passage culvert, stream relocations, revegetation measures, roadway obliteration, and elaborate temporary and permanent erosion control measures were incorporated to assure an environmentally sound project.
Robert Peccia and Associates’ (RPA’s) responsibilities in this project included all aspects of the roadway design and preparation of the Plans, Specification, and Estimate package. Other services included permit applications, preparation of right-of-way plans, utility coordination, agency and public involvement, and the right-of-way acquisition.
Coffman Cove Road CERCLA Remediation
Prince of Wales Island, Alaska
Client: Federal Highways Administration - Western Federal Lands Highway Division
Forest Service Road 3030, also known as the Coffman Cove Road, is a portion of Alaska Forest Highway (FH) 44 located on Prince of Wales Island in southeast Alaska. The 19.6-mile road is the main route linking the city of Coffman Cove to North Prince of Wales Road, and is located within the Tongass National Forest. This remediation project included multi-disciplinary site characterization studies and cleanup action work plans as part of Time-Critical Removal Actions under CERCLA authority with the United States Forest Service on Coffman Cove Road on Prince of Wales Island, Alaska. A five-mile segment of the southern end of Coffman Cove Road was impacted by acid rock drainage (ARD) resulting from pyritic rock used as road fill during road reconstruction in 2006.
Key elements of this project included the removal of or treatment of contaminated material from the road prism at 7 identified sites along the corridor as well as treatment at one waste area used in the previous reconstruction project. The extent of the removal actions and treatment along the roadway evolved with continued water quality testing through the two year life of this project. In conjunction with removal of roadway material, a material source and waste are was developed to both contain the contaminated material removed from the roadway and to provide suitable material for reconstruction of the affected portions of the roadway. As suitable material was removed from the material source, the available space was lined and filled with contaminated material. At completion, the waste area was capped with an impermeable membrane and covered. Other key elements of this project included replacement of affected culverts and repaving of the affected portions of the project corridor.
RPA’s responsibilities included the Plans, Specifications, and Estimate package for all aspects of the removal actions, waste area and road design. In addition to the site studies and remediation design plans, RPA's team will conduct long-term monitoring of the sites to assess the efficiency of the cleanup measures through 2014.
Trout Creek Road Overlay - York, Montana
Lewis & Clark County, Montana
Client: Lewis and Clark County, Montana
The Trout Creek Road project included constructing an asphalt concrete pavement overlay, and installing signing and pavement markings on a deteriorated 3.2 miles of forest road from York, MT easterly towards Vigilante Campground. This surface preservation and safety project, under Lewis and Clark County's maintenance jurisdiction, was made possible by a forest highway funding agreement with the Western Federal Lands Highway Division (WFLHD).
RPA was responsible for overall project design, bid documents, construction bid letting, administration and construction inspection. RPA prepared the environmental document authorized by WFLHD as well as completing and recording a right of way retracement certificate of survey. The overall project came in under budget by approximately $44,000, including a $3,500 change order for additional signage and miscellaneous other.
MicroStation and Geopak design softwares were used in the design and plans preparation of
