This Environmental Assessment (EA) 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 Colorado Department of Transportation (CDOT) initiated this US 24 PEL Study to examine existing transportation conditions and anticipated problem areas along the US 24 corridor in El Paso County between Powers Boulevard and the Town of Ramah. The study identified and screened a reasonable range of potential transportation improvements to develop an implementation plan for projects to meet the operational, safety, and capacity needs along the corridor. The study was conducted following Federal Highway Administration (FHWA) PEL guidance regarding the integration of transportation planning and the National Environmental Policy Act (NEPA) process, which encourages the use of planning studies to provide information for incorporation into future NEPA documents.
The purpose of this Manual is to provide guidance on preparing and processing documents that comply with NEPA and other applicable state and federal environmental laws affecting transportation projects in Colorado. This Manual provides references and links to related federal and state laws, executive orders, regulations, and policies. It also provides "best practice" examples for various compliance processes where appropriate. It is intended that CDOT staff, local agency representatives, and consultants use this Manual to implement NEPA in an effective manner, producing more consistent, improved environmental documents that decision-makers may use to make well-informed transportation decisions.
The objective of this project was to integrate the American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide, Interim Edition: A Manual of Practice and its accompanying software into the daily pavement design, evaluation, rehabilitation, management, and forensic analysis practices and operations of the Colorado Department of Transportation (CDOT).
Corrosion resistant alloys and non-metallic coating have been tested by exposure to Glenwood Springs geothermal water in a test loop constructed for the purpose adjacent to the Glenwood Springs geothermal well. Several alloys were tested. None of the materials showed any measurable degradation during the test. However, it is recommended that the results be applied with caution; several factors suggest that the data from these tests might be overly optimistic and that corrosive conditions in practice could be more severe. Based on this study and previous studies on geothermal heating of bridge decks, consideration for geothermal heating of two structures in Glenwood Canyon is underway.
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.
This document is not a regulation nor is it intended as such. It is intended to provide information and direction to applicants and their consultants in an effort to help them meet the requirements of Regulation No. 22. This guidance document is to be used in combination with Regulation No. 22. Parties seeking site location approval should obtain a copy and be familiar with Regulation No. 22.
The 1983 session of the Colorado General Assembly passed House Bill 1102 authorizing the Colorado Water Conservation Board (CWCB) to conduct a geotechnical study of dam sites in the White River Basin. The objective of the White River Geotechnical Study was to carry out surficial and sub surface geotechnical investigations of the designated dam sites and to locate and evaluate potential sources of construction material. The level of topographic data on the reservoir areas was to be upgraded.
