This finding of no significant impact has been prepared for the Federal Boulevard Improvements Project. The stretch of Federal Boulevard in the Project Area is lined by commercial development with residential development behind the businesses. Federal Boulevard serves as a high travel-demand traffic corridor. This is a local-agency project sponsored by the City and County of Denver (CCD) in conjunction with CDOT and the Federal Highway Administration (FHWA) serving as joint lead agencies.
The purpose of this paper is to provide a summary of a Value for Money analysis completed by the Colorado Department of Transportation (CDOT) and its High Performance Transportation Enterprise (HPTE) to evaluate options to construct and finance the first phase of the I-70 East project. A Value for Money analysis compares key quantitative and qualitative factors with a goal of determining the project delivery option that best fulfills CDOTs objectives, including the objective of building an affordable project on I-70 East from I-25 to I-225.
The Front Range Foothills design segment begins the accent to the Rocky Mountains from the eastern plains and the Denver metropolitan area. Significant features comprise of the hogback, scenic views including to the Continental Divide, Clear Creek, access to local and regional recreational opportunities, and communities and residential areas. The Front Range Foothills design segment contains one Area of Special Attention (ASA) at Floyd Hill.
In 2011 CDOT developed guidelines for designing bicycle and pedestrian facilities. These are included as chapter 14 of the CDOT roadway design guide. Training covers key components of the guidelines.
Characterized by rocky hillsides, canyons and montane landscape, the Western Slope Canyons and Valleys design segment is a clear transition from the alpine landscape of the Crest of the Rockies. This design segment connects the towns of Wolcott, Eagle, Dotsero and Glenwood Springs and provides scenic views of the native vegetation, rocky hillsides and Colorado River, and provides direct access to local and regional recreational destinations. The Western Slope Canyons and Valleys design segment contains two Areas of Special Attention (ASA) including the East Entrance to Glenwood Springs and the Wolcott Curves.
The objective of this study is to determine if the development of a standardized subset of bridge plans s feasible and cost effective. The past 30 years of successful Colorado Department of Transportation bridge design can be used as a starting point to create a standardized subset of bridge plans.
Full depth reclamation of asphalt pavements using asphalt emulsions is a process that recycles and rejuvenates the existing asphalt pavement surface, base, and sometimes, the subgrade, providing an improved underlying structure for the new asphalt pavement. This report provides guidance, standardized plans and specifications, construction inspection best practices materials testing procedures and frequencies, a performance evaluation process, and quality assurance and quality control protocols when constructing FDR projects.
Rising to over 10,000 feet in elevation, the Crest of the Rockies design segment provides access to numerous ski resorts and recreational opportunities through Silverthorne, Frisco, Copper Mountain, Vail, Avon and Edwards. The Crest of the Rockies offers dramatic views of peaks and valleys, steep topography, lush alpine vegetation, rocky hillsides, waterways and views of numerous ski resorts. The Crest of the Rockies design segment contains five Areas of Special Attention (ASA) including the Town of Vail, Top of Vail Pass, Dowds Junction, Herman Gulch and Silverthorne.
Colorado Department of Transportation requires revegetation as part of road construction projects. The revegetation of previously disturbed areas from highway construction activities is a critical component to overall site storm water management strategy. Poor revegetation actions during and after construction can lead to difficulty in deactivating storm water construction permits (SCPs). CDOT's specifications for revegetation projects are discussed and practical methods for successful projects are demonstrated.
The advent of solar energy utilization in highway infrastructure around the country has been increasing in recent years. Right of Ways (ROWs) have several advantages for energy development such as the existing electrical infrastructure aligned with the major highways, a secured boundary, and easy maintenance access. To understand the potential impacts on driver safety, environmental resources, and maintenance operations, case studies are presented from national and international projects. Factors associated risk impacts are analyzed qualitatively as well as quantitatively. Mitigation measures are recommended to minimize the undesirable impacts in the planning, design, construction, operation and maintenance of solar array.
