PROJECT BACKGROUND

The current interchange at I-70 and Kipling was constructed in 1967 and is located in the city limits of Wheat Ridge in Jefferson County. The interchange is currently a diamond interchange with two bridge structures (E-16-GX and E-16-GY) on I-70 over Kipling Street (State Highway 391).

SECTION 7 ENVIRONMENTAL ANALYSIS WORK TASK DESCRIPTIONS

This list establishes the consultant’s individual task responsibility. The consultant shall maintain the ability to perform all work tasks which are indicated below by an ‘X’ in the consultant column, in accordance with the forms and conditions contained herein, and the applicable CDOT standards. Selected work tasks shall be assigned only after coordination and consultation with CDOT. The Consultant is also responsible for coordinating the required work schedule for those tasks accomplished by CDOT and other agencies. The Consultant should review this entire section to identify applicable material. Contact the Colorado Department of Transportation/Project Manager (CDOT/PM) if clarification is required (see Section 2.1, CDOT Contact). The following activities of communication, consensus building, project team reviews, conceptual design, data gathering, documentation, and formal public notice should be planned by the Consultant and coordinated with the CDOT/PM. The time of their accomplishment will overlap and parallel paths of activity should be planned to finish the development phase in accordance with the shortest possible schedule. The type and number of meetings, documents, etc., will depend on the category and characteristics of the project work. A project plan shall be developed by the Consultant which satisfies the requirements of the project development. This plan must be approved by the Contract Administrator (see Section 2.1, CDOT Contact) before starting the work. The goal of the environmental analysis of this project is to definitively and comprehensively examine the transportation needs of the project area, to subject the transportation alternatives to a NEPA analysis, and to generate the appropriate NEPA documents following the requirements of CFR 23 Part 771 and the FHWA Technical Advisory T6640.8A. All environmental documentation, reports and technical memos shall be submitted to CDOT Region 1, and may be supplied to FHWA, RTD, CDOT Environmental Programs Branch (EPB) and the City of Wheat Ridge for early review as appropriate and necessary. The Consultant shall develop a range of reasonable alternatives that will satisfy the Purpose and Need requirements of the project, including, but not limited to, those identified in earlier and ongoing studies of the area. Whenever required and appropriate, CDOT will assist the Consultant in the development of conceptual layouts and preliminary design, which will satisfy the requirements for each alternative. In the process of developing alternatives, the Consultant should consider, among other factors, alternative routes, alternatives that avoid or minimize environmental impacts, accident history, congestion effects of the proposed improvements on the existing roadway system, and right-of-way impacts. The alternatives must take into account the projected opening day and design year traffic volumes as developed for this Scope, or as modified through later studies and calculations by CDOT. The Consultant shall evaluate the impacts of these alternatives according to NEPA guidelines and shall examine the degree to which these alternatives satisfy the Purpose and Need requirements of the project. The Consultant shall set out these evaluations both schematically and in narrative form for review. The process of developing alternatives could potentially be streamlined if analysis shows that an alternative from the Planning and Environmental Linkages (PEL) study that was conducted for this interchange can be carried forward into NEPA as the Preferred Alternative. In the Alternatives Chapter of the EA, the Consultant shall include a full definition of the preferred alternative for the projected opening day and 20 years into the future from the projected opening day. In addition, each of the analyzed alternatives shall be fully defined and described.

I. Major Structural Design Major structures are bridges and culverts with a total length greater than twenty feet or retaining walls with a total length greater than one hundred feet and a maximum exposed height at any section of over five feet. This length is measured along centerline of roadway for bridges and culverts, and along the top of wall for retaining walls. Overhead sign structures (sign bridges, cantilevers, and butterflies extending over traffic) are also major structures, but are exempt from the structure preliminary design activity defined here. The CDOT Structure Reviewer will participate in coordinating this activity.

the structure size, layout, type, and rehabilitation alternatives. On a continuing basis, provide support data and recommendations as necessary to finalize the structure site data.

ii Determine the structure layout alternatives. For bridges, determine the structure length, width, and span configurations that satisfy all horizontal and vertical clearance criteria. For walls, determine the necessary top and bottom of wall profiles.

iii Determine the structure type alternatives. For bridges, consider precast and cast-in-place concrete and steel superstructures and determine the spans and depths for each. For walls, determine the feasible wall types.

iv Determine the foundation alternatives. Consider piles, drilled caissons, spread footings, and mechanically stabilized earth foundations based on geology information from existing structures and early estimates from the project geologist. To obtain supporting information, initiate the foundation investigation as early as possible during the preliminary design phase.

v Determine the rehabilitation alternatives. Continued use of all or parts of existing structures shall be considered as applicable. The condition of existing structures shall be investigated and reported. Determine the modifications and rehabilitation necessary to use all or parts of existing structures and the associated costs.
