Dismissed Alternatives

RTD was required to rigorously explore and objectively evaluate a
reasonable range of alternatives during the Gold Line Environmental
Impact Statement (EIS). As the range of alternatives was narrowed, they
underwent multiple levels of increasingly detailed and quantitative
analysis. The goal was to eliminate flawed or unsupported alternatives
from consideration. At each level of technical analysis, the support of
the public, local municipalities and regulatory agencies was also taken
into account. This process allowed RTD to identify the Preferred
Alternative that was included in the Final Environmental Impact
Statement. Summarized below are the various alternatives that were
eliminated at each level of EIS screening.

Alternative Dismissed in Level 4 Screening

During the fourth level of screening, the team optimized both remaining alternatives to improve their performance and conducted even more detailed evaluations. The team established the number of stations for both of the two remaining alternatives and determined station-specific parking demand.  Various footprints for station platforms and parking were also evaluated.

Alternatives Dismissed in Level 3 Screening

The third level of evaluation provided more detailed answers to many questions including ridership, environmental consequences, ways to avoid property impacts, feasibility of the implementation of the alternatives, and more detailed cost estimates.  It also provided the first glimpse at other key evaluation criteria such as parking demand at preliminary station locations.

Alternatives Dismissed in Level 2 Screening


Level 2 Screening analyzed alternatives based on a number of preliminary quantitative criteria, including environmental impacts/benefits, community impacts/benefits, projected ridership and travel time. For a full list of criteria and the results for each alternative evaluated, click here. The following alternatives were eliminated at this phase:

Alternatives Dismissed in Level 1 Screening


Level 1 Screening, commonly called Fatal Flaw Screening was a primarily qualitative analysis of alternatives to determine if there are significant issues (e.g. cost, environmental impacts, not constructable).

during Level 1, including the one selected for further evaluation.

 ALTERNATIVE DESCRIPTION REASON DISMISSED 
Alternative 3A  Electric commuter rail paralleling the BN/UP corridor to the South Cannot
meet legal requirements; may exceed FasTracks budget due to property
acquisitions, environmental impacts and grade separations.
Alternative 3B  Electric commuter rail paralleling the BN/UP corridor to the North Cannot
meet legal requirements; may exceed FasTracks budget due to property
acquisitions, environmental impacts and grade separations.
Alternative 3C  Electric commuter rail on a new arterial street Cannot meet turning radius or legal requirements for operating on street alignments.

ALTERNATIVE DESCRIPTION REASON DISMISSED
Alternative 4A Diesel commuter rail paralleling the BN/UP corridor to the South  Cannot
meet legal requirements; may exceed FasTracks budget due to property
acquisitions, environmental impacts and grade separations.
Alternative 4B Diesel commuter rail paralleling the BN/UP corridor to the North  Cannot
meet legal requirements; may exceed FasTracks budget due to property
acquisitions, environmental impacts and grade separations.
Alternative 4C Diesel commuter rail on a new arterial street alignment  Cannot meet turning radius or legal requirements for operating on street alignments.

ALTERNATIVE DESCRIPTION REASON DISMISSED
Alternative   5   Light rail on the BN/UP right-of-way  Union Pacific Railroad will not allow light rail trains to operate in its right-of-way.
Alternative   5A Light rail paralleling the BN/UP corridor to the South  May exceed FasTracks budget due to property acquisitions.
Alternative      5B Light rail paralleling the BN/UP corridor to the North May exceed FasTracks budget due to property acquisitions.

ALTERNATIVE DESCRIPTION REASON DISMISSED
Alternative 6A  Light rail north on Pecos to the BN/UP corridor  Narrow right-of-way for long stretches on Pecos and major property acquisitions.
Alternative 6C  Light rail north on Federal to 52nd  Federal is a congested state/US highway.
Alternative 6E  Light rail north on Sheridan to 44th Wadsworth is a congested state highway.
